Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to an intelligent safety reclosing circuit breaker. Background technique [0002] Circuit breakers are commonly used devices in the field of electrical engineering, and their main function is to close and break circuits. The circuit breaker can cut off the circuit under abnormal conditions such as short circuit or severe overload, so as to effectively protect the devices in the path. [0003] At present, the traditional low-voltage circuit breaker mainly relies on manually pulling the handle for opening and closing operations, but this method has a low degree of mechanization. In order to solve the problem of low mechanization of the manual pulling handle, an electric transmission mechanism with auxiliary functions has appeared. However, this kind of electric transmission structure can only be loaded on the outside of the low-voltage circuit breaker, and the opening and cl...

Problems solved by technology

[0003] At present, the traditional low-voltage circuit breaker mainly relies on manually pulling the handle for opening and closing operations, but this method has a low degree of mechanization. In order to solve the problem of low mechanization of the manual pulling handle, an electric transmission mechanism with auxiliary functions has appeared. However, this kind of electric transmission structure can only be loaded on the outside of the low-voltage circuit breaker, and the opening and closing operation is realized by controlling the manual operation push rod. The installation is cumbersome and the operation stability is poor; function, but there are problems such as single protection function, inability to dynamically detect various circuit parameters of the corresponding electrical equipment, and inability to set the detection parameters of the electrical equipment according to the usage situation, and the low degree of intelligence
