Problems solved by technology

[0002] The existing circuit breakers have a single function, most of which can only realize overload and circuit breaker protection, and cannot be used for intelligent applications in the field of automatic control. Only through the combination of various external functional modules can the components of the combination be compatible The reliability is not high, the assembly is not easy, and it takes up a lot of space, which cannot meet the needs of the current smart grid construction

Abstract

The invention relates to an intelligent molded case circuit breaker comprising a bottom box, a middle cover, an upper cover, a handle, an electric operating mechanism for controlling the opening and closing of the circuit breaker and an opening and closing state indicating device for displaying the state of the circuit breaker. The middle cover covers the upper part of the bottom box. The upper cover covers upper part of the middle cover. The electric operating mechanism and the opening and closing state indicating device are arranged on the middle cover. The handle is connected in the bottombox and penetrates through the middle cover. The handle stretches out of the upper cover. The opening and closing state indicating device is arranged on the left side of the electric operating mechanism. A circuit board for controlling the circuit breaker is jointly connected on the upper parts of the electric operating mechanism and the opening and closing state indicating device. The circuit board is arranged on the bottom of the upper cover. The intelligent molded case circuit breaker has the advantages of small space occupation and various functions and can switch between the manual stateand the automatic state and has the function of indicating the opening and closing state of the circuit breaker.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to an intelligent plastic case circuit breaker. Background technique [0002] The existing circuit breakers have a single function, most of which can only realize overload and circuit breaker protection, and cannot be used for intelligent applications in the field of automatic control. Only through the combination of various external functional modules can the components of the combination be compatible The reliability is not high, the assembly is not easy, and it takes up a lot of space, which cannot meet the needs of the current smart grid construction. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an intelligent molded case circuit breaker, an electric operating mechanism for controlling the opening and closing of the circuit breaker and an indicating device for indicating the opening and closing state of t...
