TECHNICAL FIELD

[0001] The utility model belongs to the technical field of intelligent circuit breaker, especially relates to a safe intelligent circuit breaker. BACKGROUND

[0002] The intelligent circuit breaker is an electrical element for distributing electric energy and controlling the circuit, and belongs to the intelligent low-voltage electrical apparatus. The intelligent circuit breaker is mainly composed of an intelligent control module and a circuit breaker. The intelligent circuit breaker has multiple protection functions, such as overcurrent, overload, overvoltage, undervoltage, short circuit, and leakage protection. The intelligent circuit breaker can monitor the circuit state in real time, quickly respond to abnormal conditions, and effectively prevent electrical fires and other safety accidents.

[0003] The Chinese patent with the publication number CN220290730U discloses a secure intelligent circuit breaker, which comprises an intelligent circuit breaker body, a plurality of lower connection grooves are formed in the lower end of the intelligent circuit breaker body, a plurality of upper connection grooves are formed in the upper end of the intelligent circuit breaker body, a dustproof device is movably connected to the upper end of the intelligent circuit breaker body, and an encryption device is fixedly connected to the front end of the intelligent circuit breaker body.

[0004] In the actual use and operation of the above-mentioned prior art intelligent circuit breaker, we find that there are still some deficiencies, such as the structure of the intelligent control module of the intelligent circuit breaker. Currently, the structure mainly includes two types. One type is that the intelligent control module and the circuit breaker are integrated. This type cannot be maintained subsequently. The other type is that the intelligent control module is installed on the circuit breaker through a shell cover combined with screws. However, when disassembling, a special disassembling tool is needed to open the shell cover to maintain the internal intelligent control module. In addition, the traditional circuit breaker generally does not have a function of dissipating heat for the intelligent module. However, the intelligent circuit breaker works continuously, and the internal circuit elements are prone to aging and failure. UTILITY MODEL CONTENTS
