, Description:TECHNICAL FIELD
[0001] The present disclosure relates to the field of protection device such as circuit breaker, and more specifically relates to, a circuit breaker having a magnetic tripping unit for short circuit protection.

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] Electrical switching apparatus, such as circuit breakers, provide protection for electrical systems from electrical fault conditions such as, for example, current overloads, short circuits, abnormal voltage and other fault conditions. Typically, circuit breakers include an operating mechanism which opens electrical contact assemblies to interrupt the flow of current trough the conductors of an electrical system in response to such fault conditions. A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overcurrent, typically resulting from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation.
[0004] Circuit breaker is a switching device designed to make, carry and break the circuit. A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overcurrent, typically resulting from an overload or short circuit. Circuit breakers are generally installed to protect equipment from overcurrent (than its rated current) situations, for example, when a short circuit or ground fault occurs in an electrical supply conductor. Upon the occurrence of any such overcurrent condition, electrical contacts inside circuit breaker get opened, and stop supply of electrical current to equipment. Designs for circuit breakers generally include accommodations for both high quiescent currents and high withstand currents. To maintain a high withstand current rating, the contacts must be locked closed at the current withstand rating and be able to withstand the large electrodynamic repulsion forces generated by the current flow. With the increase of industry size and automation, the requirement of protection devices has also increased.
[0005] Switching devices like, circuit breaker provides protection against very high current produced during short circuit. This type of protection is provided in many circuit breakers through magnetic trip-unit. Circuit breaker typically have at least one solid stationary Electrical contacts coupled/uncoupled to a solid moving Electrical contact, which provides a path to carry or interrupt the electrical current in the network. Shaft enables holding of electrical moving contact in single/ double break arrangement that helps in make & break of Electrical contacts (Stationary and Fixed) under normal and abnormal conditions(High current). The shaft of the circuit breaker has to be rotated by operating mechanism for switching MCCB ON/OFF. In abnormal condition in the system to be detected by thermal magnetic release, which gives signal to the mechanism for tripping by rotating the Trip-plate, on which the operating mechanism latches. The Switching device should interrupt the high current arising due to abnormal conditions in the network, as rapidly as possible to minimize damage caused by thermal and mechanical stresses to the equipment installed downstream.
[0006] Efforts have been made in related art to address above stated problem by using a circuit breaker. An example of such of the circuit breaker is recited in a United States Patent 942501, entitled “Magnetic tripping device and overcurrent tripping device of an electrical switch and electrical switch and method for calibrating the magnetic tripping of a magnetic tripping device”. The patent talks about the arrangement of components in magnetic system. Armature is hinged to non-magnetic current carrying conductor, to avoid distortion of magnetic flux density between armature & Yoke. Extension spring is used for holding armature against electrodynamic pull and the extension hook position can be varied for making various rating. The patent discloses an overcurrent tripping device of an electrical switch for interrupting a current flow in an electrical circuit in the event of the occurrence of an overload or a short circuit is disclosed. In an embodiment, the overcurrent tripping device includes a thermal tripping device and a magnetic tripping device. A magnetic tripping device is disclosed which, in an embodiment, includes at least one yoke element for generating a magnetic field, an armature element responding to the magnetic field, and a spring element. The armature element is arranged on an armature carrier element, separated from the yoke element, by way of a first armature element end and is mounted pivotably about an armature element rotation axis. In addition, an electrical switch including an overcurrent tripping device, and a method for calibrating magnetic tripping of a magnetic tripping device of an electrical switch, are disclosed.
[0007] However, in the conventional circuit breaker, less magnetic flux density is generated which further leads to generation of less electrodynamic force. Further, in the existing circuit breaker, variation in air gap between the Fixed and moving core between different samples leading to variation in performance. Furthermore, in the conventional circuit breaker, Variation in spring opposition force on moving magnetic core on different samples.
[0008] Whereas there is certainly nothing wrong with existing circuit breaker, nonetheless, there still exist a need to provide an efficient, effective, reliable, and improved magnetic system with minimal variation in performance from sample to sample. Further, there is a need of a circuit breaker with a magnetic tripping module that senses high abnormal current flowing in the system and actuates accordingly to give signal to the operating mechanism. Furthermore, there is a need of a circuit breaker with moving magnetic core has higher cross section along the flux path with less material thickness leading to generation of high flux density and high electrodynamic force.

[00063] FIG. 1 illustrates a magnetic system in unactuated condition, in accordance with an exemplary embodiment of the present disclosure.
[00064] As shown in FIG. 1, the view of Magnetic system module in unactuated condition. The current is being carried through the rear terminal 10 to bimetal 11 and then to the conductors through braid. Fixed magnetic core 12 of the magnetic system can be fixed to the rear terminal 10. Moving magnetic core assembly can include U shaped moving magnetic core 14 with both side walls with different mating rectangular surfaces, which is fixed on the non-magnetic actuator 13. Moving magnetic assembly can be axially hinged on the fixed core and its position at unactuated condition is defined by Stopper 16 which is fixed on the magnetic fixed core.
[00065] Current passing through the rear terminal 10 and bimetal 11 can produce magnetic flux. Produced flux can pass through magnetic fixed core 12 to the magnetic moving core 14, and thus electromagnetic force is generated on the magnetic moving core 14. Moving magnetic assembly rest on the stopper 16 in unactuated condition FIG. 1. With compression spring 17 opposing the movement of moving magnetic assembly towards the fixed magnetic core 12. Position of Stopper 16 for holding moving magnetic assembly is on the extreme end of the moving magnetic assembly away from the hinge axis 13.1. Stopper 16 reduces the variation of air-gap between fixed magnetic core 12 and moving magnetic core 14 in assembly.
[00066] High current leads to generation of high electrodynamic force on moving magnetic core 14, which is attracted towards the fixed magnetic core 12 overcoming the opposing spring force. Moving magnetic core 14 which is attached to the non-magnetic actuator 13 moves towards the fixed magnetic core 12 thus the actuating leg 13.2 of the moving magnetic core pushes the trip-plate of mechanism. Mechanism operates the contact system by separating the moving contact from the fixed contact.
[00067] In an embodiment, spring end rest on the moving magnetic core 14 and other end on stopper 16. Same stopper 16 can be used for holding moving magnetic core 14 so any variation in position of magnetic core can be compensated by same variation opposing spring force.
