, Description:TECHNICAL FIELD
[0001] The present disclosure generally relates to the field of circuit breakers. In particular, the present disclosure relates to a system and method for measuring over travel of a molded case circuit breaker (MCCB) automatically by using optical ranging and sensing.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Typically, a circuit breaker is a switching device that can close, carry and break current under normal circuit conditions, and can close and carry current under abnormal loop conditions within a specified time. The abnormal loop conditions can also include short-circuit conditions as well. The circuit breaker can be used to distribute electric energy, start motor or any other electrical device frequently, and protect the power line and the motor. When an electrical circuit is severely overloaded, short-circuited, or provided with under-voltage faults, the circuit can be automatically cut off by using circuit breaker that is attached to the circuit, and its function is equivalent to the fuse switch. In combination with an over-current thermal relay, etc., it is generally not necessary to change parts after breaking the fault current. Circuit breakers are usually reset after they have been tripped. This is the advantage of using circuit breakers instead of using traditional fuses in the circuit. The fuses cannot be reset again for use in the circuits.
[0004] Molded or moulded case circuit breaker (MCCB) is a kind of circuit breaker. As mentioned above, MCCB is an electro-mechanical device to protect the electrical circuit from short circuit current and overload current. The MCCB can protect a circuit that has a range from 63 Amps to 3000 Amps, and can be used for a wide range of voltages and frequencies of both 50 Hz and 60 Hz. The primary functions of MCCB are to manually open the circuit, and automatically open the circuit under short circuit or overload conditions. In an electrical circuit, the over current may result in faulty design of the circuit. The trip setting of MCCBs can be adjustable.
[0005] Conventionally, the MCCB can include one or more poles. Each pole includes one moveable upper contact and fixed or static lower contact. The opening distance is the shortest distance between the static or fixed (i.e. lower) contact and the moving (i.e. upper) contact when the circuit breaker is in the open state. After removing the static contact, the distance moved by the moving contact is measured and is termed as a second distance. The difference between the second distance and the opening distance is the over travel value of the corresponding contact pair (i.e. upper contact and lower contact) of the MCCB. The values of open distance, second distance and over travel are critical in order to maintain the quality of the MCCB. MCCB can include one or more poles with corresponding one or more contact pairs.
[0006] Efforts have been made in the related art to measure over travel values of the circuit breakers. Various traditional systems and methods are implemented for measuring over travel of the MCCBs. Most of the traditional systems are manually operated, and they implement a contact based over travel measurements by using vernier callipers and/or by using any other distance reading instruments. All these instruments are in contact with the MCCB physically.
[0007] European Patent documentEP1466336 describes a method for determining wear of contacts of poles in a switch unit that includes power poles provided with contacts that are actuated by a control electromagnet whose movement between an open position and a closed position is controlled by an excitation coil. The contact wear is determined from a travel time of the contact wear race. Further, the method measures travel time by measuring electrical signal representative of the conductive state of pole of power by measuring an excitation current circulating in the electromagnet coil, and by calculating the time difference between the contact closing time that is determined from the electric signal, and the instant of end of the movement of closing of the electromagnet that is determined from the excitation current. However, the cited reference does not disclose any non-contact means to determine over travel parameter of moving contacts automatically by simulating a wear off condition on the contacts junction.
[0008] German Patent documentDE4326640 discloses a measuring device for a moveable switching contact of an electrical switching device. The measuring device includes sensors and each sensor has an opto-transmitter, an opto-electric opto-receiver and a disc. The disc is coupled to the moving switching contact and on which tracks of an incremental grating scale are arranged. The light transmitted between the opto-transmitter and opto-receiver is influenced in a manner typical of the end position i.e. total travelled position of the moving switching contact by a track only in one end position of the contact, and by a further track only in the other end position of the contact. However, the cited reference does not disclose any non-contact means to determine over travel parameter of moving contacts automatically without using any physical restraints and/or links with the moving contacts.
[0009] As can be seen, most of the prior art references use manual and/or contact-based techniques to measure over travel of the circuit breakers. There are various drawbacks with these techniques. The drawbacks can be calculation of wrong readings with many human errors due to wrong combination of contacts during distance readings of the contacts, and during difference calculation. This may lead to customer complaints on working of the MCCBs. The data recording and calculation of over travel distance may consume a lot of time, involve a lot of paperwork, require additional measuring devices etc., and it is a tiring process. Further, these techniques depend on the operator who carries the measurement of over travel readings, and this may lead to the occurrence of parallax errors. During over travel measurement, forces exerted by the vernier callipers probes may give misleading results of over travel. These contact-based techniques may cause damage to the MCCBs while measuring over travel of the MCCBs respectively.
[00010] Whereas there is certainly nothing wrong with traditional systems or methods, nonetheless, there still exists a need in the art to provide a simple, easy, cost-effective and reliable system and a method to measure over travel of the circuit breaker with enhanced accuracy, and without causing any damage to the circuit breaker while measuring the over travel distance of the moveable contacts.

The consecutive readings of over travel are calculated and are compared with first readings in order to remove shroud interferences. These readings of initial distance are corresponding to first pole i.e. pole A. Each pole can include at least one contact pair. Each of the at least one contact pair can include one upper contact and one lower contact respectively.
[000120] In an embodiment, the method then measures the final distance travelled by the upper contacts after removing the lower contact of the pole A, and readings are displayed on the screen. The consecutive readings corresponding to the final distance are calculated, and are compared with first readings in order to remove shroud interferences. These readings of final distance are corresponding to the pole A. The difference between readings corresponding to the initial and final distances (i.e. with and without lower contacts) are measured as over travel for the corresponding upper contact of the pole and the measured over travel data is displayed on the screen. If the measured over travel is beyond the predetermined range, then the pole or upper contact or finger head of the pole can be considered as fail. If the measured over travel is within the predetermined range, then the pole or upper contact or finger head of the pole can be considered as pass. The method is repeated for all the poles such as poles R, Y, B & N present in the circuit breaker (i.e. MCCB). If any pole or contact pair is failed, then the MCCB is considered as fail. If all the poles or contact pairs are passed, then the MCCB is considered as pass.
[000121] In an embodiment, the method can update readings on the server, update current barcode to previous barcode. After measuring over travel of the circuit breaker i.e. MCCB, the laser sensor can be moved to home position and the breaker test count can be incremented.
