Technical Field
[0001] The utility model relates to the technical field of circuit breakers, and particularly relates to a universal circuit breaker with a peripheral protection component. Background Technique
[0002] In terms of structure, a universal circuit breaker usually consists of electromagnetic triggers, thermal triggers, thermal-magnetic triggers, electronic triggers, etc. These triggers detect abnormal conditions in the circuit through different mechanisms, such as overload, short circuit or ground fault, etc. When an abnormal condition is detected, the universal circuit breaker can quickly cut off the circuit to protect electrical equipment from damage;
[0003] In a protection device of a universal circuit breaker with the publication number of CN218633056U, it includes a protection frame. The inner bottom wall of the protection frame is fixedly installed with a circuit breaker. A plurality of strip-shaped chutes are opened on the opposite inner walls of the protection frame. Installation blocks are arranged on the opposite outer walls of the circuit breaker. Through holes are opened on the opposite side walls of the protection frame. A positioning pin penetrates through the through hole. The end of the positioning pin located outside the protection frame is fixedly connected with a pull plate. A return spring is arranged between the pull plate and the protection frame. The return spring is wound around the outer wall of the positioning pin. In the utility model, the circuit breaker is protected by the arranged protection frame. And to facilitate the disassembly and assembly between the circuit breaker and the protection frame, through the cooperation among the strip-shaped chute, the installation block, the positioning pin, the return spring and the pull plate, the circuit breaker is detachably and fixedly installed in the protection frame, and the outer wall of the circuit breaker does not contact the side wall of the protection frame, thereby improving the heat dissipation effect of the circuit breaker;
[0004] When the above-mentioned existing circuit breaker is in use, it can only protect the circuit breaker. However, when the circuit breaker is in use, the switch of the circuit breaker is generally manually rotated to open and close. However, the switch lacks a good external locking design, which may cause the switch to be accidentally touched by non-operators, possibly leading to safety accidents. And due to misoperation, the stability of the electrical system is poor, affecting power use. Therefore, improvements are needed. Content of the Utility Model
