DESC:TECHNICAL FIELD

The present subject matter described herein, in general relates to a circuit breaker or switchgears, and more particularly, to a distant detection of a status of the circuit breaker and control of the circuit breaker using a communication device

BACKGROUND

Electrical distribution boards or panels generally consist of a number of devices like incomers, outgoing etc. One of the most significant devices placed in an electrical distribution board is a circuit breaker. A circuit breaker is a switching device used for protection of electrical devices for problematic conditions like electrical fires and electrocution. Under fault conditions, like short circuit, overload etc, the circuit breakers provide a method to break open the electrical circuit, thus protecting the devices in the Loop from facing damage.

Switchgears include simple one-time usable protection devices like Fuses to devices like Molded Case Circuit Breakers (MCCB), Miniature Circuit Breakers, and Air Circuit Breakers. To carry out the function of protection, these circuit breakers consist of a pair of separable contacts, which sense the fault condition and thus disengage or trip. This tripping mechanism is reset into position once the fault is cleared out, either by manual reset or by a remote operator that can remotely reset the circuit breaker.

Miniature circuit breakers consist of two separate pairs of potential free contacts. The first pair of contacts is an auxiliary contacts that have ‘Normally open’ or ‘Normally Closed’ contacts. These contacts are linked with the ON- OFF mechanism of the Miniature circuit Breaker. For Example, when the miniature circuit breaker is in ‘ON’ condition, the ‘Normally Open’ terminals of the auxiliary contact would close, thus indicating the circuit breaker in ON condition.

Another pair of potential free contact is that of the trip alarm contact. The trip alarm contact changes it state only upon the indication of a trip. These mechanical contacts are intricately linked with the Circuit breaker to give an indication of the trip or ON-OFF status of the circuit breaker.

Typically, the miniature circuit breaker, along with the Auxiliary contact and the trip alarm contact are all mounted on a DIN RAIL and enclosed within a distribution board, along with other electrical devices like energy meters etc. The only indication of trip or of the ON- OFF status that are available are from the front panel of the circuit breaker or the operating handle, which most likely tends to get hidden when the distribution board is covered with a front protective hinged door. This situation may get problematic especially when the user and the distribution board are located at distances quite away from each other. For Example, residents of a building may not directly be able to identify that a circuit breaker has tripped. Moreover, the situation may worsen in applications where temperature is a critical parameter like cold storage, where the user may not notice that an MCB has tripped due to a fault, the only indication would be the smell of rotten food after several days. Thus a system is required to monitor the status of the MCB from a distant location using a communication device that would submit an immediate indication of either trip of an MCB or any status change take place on the MCB.

Under vivid situations, it is also likely that the circuit breaker maybe placed at a location where physically operation of turning ON or OFF of the circuit breaker may not be feasible. In such a situation, remote operation of a circuit breaker is also necessary to control the ON-OFF status of the circuit breaker. Thus, there is a need for a protocol for isolated detection of the status of a circuit breaker and control the circuit breaker using a wired or wireless communication Device.
In spite of various available techniques in the prior-art for calibration of circuit breakers and controlling the working of circuit breakers, there still exists a need to provide a standalone device, which is compact in nature and does not require any other communication module for detecting the status of the circuit breaker and also to control the working of the same.

In one implementation, the present invention relates to an apparatus and method thereof for status detection and control of circuit breakers.

In one implementation, the present invention relates generally to the field of circuit breakers, more specifically to the distant detection of the status of the circuit breaker and control of the circuit breaker using a communication device, interfaced with the circuit breaker. This invention also includes a feature to communicate the Status of the circuit breaker to a host device located at a distance using wireless or wired Protocol.

Referring now to figure 1, a system (100) for detecting status of at least one circuit breaker (102, 201) and to control operations of said at least one circuit breaker (102, 201) is disclosed. The system comprises of a communication device (103, 205) configured to detect said status of said at least one circuit breaker (102, 201), and at least one computing device (106, 207) configured to control operations of said at least one circuit breaker (102, 201), wherein said communication device (103, 205) is communicably coupled with said at least one computing device (106, 207) using a network (105, 206).

In one implementation, said at least one circuit breaker (102, 201) comprises at least two pairs of potential free contacts communicable coupled to provided an indication of a status of said at least one circuit breaker (102, 201), wherein at least one pair of said potential free contacts are an auxiliary contacts coupled to ON-OFF mechanism of said at least one circuit breaker and provides ON-OFF status indication; and at least one other pair of said potential free contacts are coupled to a trip alarm contact and provides a trip command status indication, wherein said trip alarm contact changes its state only upon an indication of said trip command.

In one implementation, an output of said at least two pairs of potential free contacts are provided as input to said communication device (103, 205), wherein said output is ‘Normally Closed’ (NC) or ‘Normally Open’ (NO).

In one implementation, the system further comprises a converter communicable coupled with said communication device (103, 205), and configured to communicate with said at least one computing device (106, 207).

In one implementation, the system further comprises an AUX supply means configured to supply an auxiliary voltage to said communication device (103, 205) and said converter for their working.

In one implementation, said at least one computing device (106, 207) communicates with said at least one circuit breaker (102, 201) using said communication device (103, 205); thereby controlling the operations of said at least one circuit breaker (102, 21).

Referring now to figure 2, a pictorial view of the entire system, which includes the circuit breaker, communication device and other accessories connected with the host system are shown. As shown in figure 1, a circuit breaker (102) consists of two separate pairs of potential free contacts. The first pair of contacts is an auxiliary contacts that have ‘Normally open’ or ‘Normally Closed’ contacts. These contacts are linked with the ON- OFF mechanism of the Miniature circuit Breaker. For Example, when the Miniature Circuit Breaker is in ‘ON’ condition, the ‘Normally Open’ terminals of the auxiliary contact would close, thus indicating the circuit breaker in ON condition.

Another pair of potential free contact is that of the trip alarm contact. The trip alarm contact changes it state only upon the indication of a trip. These mechanical contacts are intricately linked with the circuit breaker to give an indication of the trip or ON-OFF status of the circuit breaker. The contact outputs, either ‘Normally Closed’ (NC) or ‘Normally Open’ (NO) are given to the input terminals of the communication device (103). An auxiliary supply voltage (101) is used to power up the communication device (103), and the RS 485 to an Ethernet converter (104). The Ethernet output is connected to the router (105), through a LAN cable, for wireless connection. Appropriate settings in the host computer (106) are made in order to communicate with the router (105) and thus in turn communicate with the circuit breaker (102). The output of the communication device (103) is connected to the circuit breaker to control the operation of the circuit Breaker.

Referring now to figure 3, a simplified functional block diagram of the communication device required for the isolated detection of status and control of circuit breaker of the invention is shown. The figure 2 provides a detailed explanation of the working of the isolated detection system. A circuit breaker with an auxiliary and trip alarm contacts (201) connected to the communication device (205). The NO or NC contacts of the circuit breaker are given to the status sensor circuit (202). The status sensor circuit (202) corresponds to two major functions. Firstly, on sensing a status on its input terminals from the circuit breaker, it transfers a corresponding High or Low status at the input of the microcontroller circuit (203)(203). It sends a High signal level at the input of the microcontroller circuit (203), when an NO contact closes or an NC contact opens. The Status sensor circuit (202), otherwise sends a Low signal Level when an NO contact remains open or an NC contact remains closed. The Second function performed by the status sensor circuit (202) is local display of the status of the circuit breaker. When an NO contact closes, the communication device (205) reads it as the circuit breaker (201) has been turned ‘ON’. As such, the communication device (205) gives an LED display, indicating this status change. Correspondingly, when an NC contact opens, the communication device (205), reads it as a circuit breaker (201) has tripped. As such, the communication device (205) gives an LED display, indicating this specific change. This local display of status change is performed by the status sensor circuit (202).

Once the status level High or Low is communicated to the microcontroller circuit (203) (203), the microcontroller circuit (203) (203), decodes the signal in a form compatible with RS485 protocol. Hence, the microcontroller circuit (203) (203) sends a series of signals, through the transmission pin of the microcontroller to the RS 485 Driver circuit, which converts the response of the microcontroller into differential voltage signals in the form of D+ and D- lines. Hence, the Microcontroller, which is already communicating with the host computer (207) through the RS485 to Ethernet converter (206), sends a status change command to the host computer (207), which is displayed on the human machine interface on the host computer (207).

In one implementation, a communication device (103, 205) for detecting status of at least one circuit breaker (102, 201) and to control operations of said at least one circuit breaker (102, 201) is disclosed. The communication device (103, 205) comprises a status sensor circuit (202) configured to sense, from at least one circuit breaker (102, 201), a status signal on at least one input terminal, transmit said sensed status signal to a microcontroller circuit (203), and display, on a display, said status of said at least one circuit breaker. The said microcontroller circuit (203) configured to receive, from said status sensor circuit (202), said status signal as input, decode said status signal in a compatible format to generate at least one decoded signal, transmit a series of signals, using at least one transmission pin to a convertor thereby communicate with at least one computing device (106, 207) using a network (105, 206), receive, from said at least one computing device (106, 207) using said network (105, 206), at least one command signal to control operations of said at least one circuit breaker (102, 201) and initiate a control circuit (204) by sending a initiate signal. The said control circuit (204) configured to receive, from said microcontroller circuit (203), said initiate signal, thereby control operations of said at least one circuit breaker (102, 201).

In one implementation, at least two pairs of potential free contacts of said at least one circuit breaker (102, 201) providing said status signal in the form of Normally Closed’ (NC) or ‘Normally Open’ (NO) as output are coupled with status sensor circuit (202).

In one implementation, the communication device is characterized in that said status sensor circuit (202) transmits a high signal level to said input of said microcontroller circuit (203), when said NO contact closes or said NC contact opens; and a low signal level to said input of said microcontroller circuit (203), when said NO contact open or said NC contact closed.

In one implementation, the display is configured to display status of said at least one circuit breaker (102, 201) comprises turned ‘ON’ when said NO contact closes; and tripped when said NC contact opens.

In one implementation, said decoded status signals are converted to a RS 232 compatible format or an Ethernet compatible format.

In one implementation, said microcontroller circuit (203) transmit said series of signals a circuit configured to convert said series of signals into differential voltage signals.

In one implementation, said communication device communicates with said at least one computing device (106, 207) using said network (105, 206) by sending status change commands and receiving at least one command signal to control operations of said at least one circuit breaker (102, 201).

In one implementation, the sequence in which the communication device interacts with the host computer is explained in figure 4.However, if the user wishes to change the status of the circuit breaker, that is, to turn an already ON circuit breaker (201), OFF or turn an OFF circuit breaker ON, the user can do so using the human machine interface on his host computer (207). By giving an appropriate command, the user can send a signal through the host computer (207). The host computer (207) then passes the command to the RS485 to Ethernet converter (206), which converts the Ethernet signal to a signal compatible to RS-485 protocol, which can then be read by the microcontroller circuit (203) in the communication device (204). Once the microcontroller circuit (203) receives the control signal from the host computer (207), it initiates the control circuit (204), which consists of a relay network, to carry out the function of changing the state of the circuit breaker (201). Thus, the functionality of isolated detection of the state of the circuit breaker (201) and the control of changing the state of the circuit breaker (201) is carried out efficiently.

Referring now to figure 4, a detailed flowchart of the steps involved in the initial setup of communication of the host computer (207) with the communication device (205) is shown.

In one implementation, the communication device (205) is communicating with the host computer (207) through wireless fidelity (Wi-Fi) Technology. The hardware setup for the same would comprise of routing the RS-485 lines, D+ and D- lines to the RS-485 to Ethernet converter (206). The output of the Converter (206) is then sent to a router through a LAN cable. The Internet Protocol Address of the router is set in correspondence with the communication device (205) and the host computer (207) and thus the communication device (205), the router and the host computer (207) are configured on the same platform.

Once the communication is set up, we can begin with the configuration of the communication device (205),(which acts as a slave device) with respect to the host computer (207) (which acts as the master device). Since we are following the master- slave configuration, a particular baud rate, slave address, parity bit, stop bit (301), for the communication device (205) and give a similar input at the host Computer (207) end is set. Only once the master detects the particular slave it has to communicate with (according to the slave address set), will the communication be completely established.

Once the configuration setup has been made by entering the baud rate, slave address (301), the user turns on the communication portal to check if it is communicating (302). If the communication is successfully established, the Host computer (207) (master), begins to continuously poll the slave at a predefined polling rate. However if the communication is not successfully established, then the user may have to check the hardware or the configuration parameters involved in the communication to establish.

Once the communication is successfully established, the host computer (207)(master), begins to continuously poll the slave at a predefined polling rate (304). If any status change is noticed (306) by the communication device (205), through the circuit breaker (201), the same is communicated to the host computer (207) in the consecutive polling sequence. If no status change is noticed, then the polling is continued as before. As mentioned earlier, this invention is not limited to Wireless communication technology of Wi-Fi, but can be extended to other wireless technologies like Bluetooth and Zigbee. For Robust wired technologies like RS-(232) or 4 wired RS-485, the adaptation would be required at the converter (206) end however the output of the communication device (205), remains the same. The scope of this invention is not limited to a particular method or communication technology but on the contrary, the intention is to cover all the modifications, equivalents and alternatives to the invention disclosed here within.

In one implementation, a communication module is purely outside the breaker.

In one implementation, the invention specifically talks about the communication with an electro-mechanical breaker, which does not make use of an electronic trip unit. Since no electronic trip unit is involved in the circuit breaker, the question of calibrating it etc., does not arise. The communication device mentioned in the invention senses the status of the Miniature Circuit Breaker with the help of an auxiliary and trip alarm contacts and with the help of the Graphic User interface, is capable of controlling the ON- OFF command of the Circuit Breaker or any other Load involved.

Referring now to figure 5, a method (500) for detecting status of at least one circuit breaker (102, 201) and to control operations of said at least one circuit breaker (102, 201) using a communication device (103, 205) is disclosed. The method comprises the steps of:

At step 502, a status signal on at least one input terminal of a communication device (103, 205) is sensed from at least one circuit breaker (102, 201).

At step 504, said sensed status signal are transmitted to a microcontroller circuit (203).

At step 510, a status of said at least one circuit breaker, is displayed on a display of said communication device (103, 205) and a display of said at least one computing device (106, 207).

At step 512, at least one command signal is received from said at least one computing device (106, 207) using said network (105, 206), to control operations of said at least one circuit breaker (102, 201).
