[0037] In this embodiment, a guide rail 9 is provided at the left portion of the lower end of the base 1, a relay body 10 is installed at the middle portion of the rear seat wall of the base 1, an outgoing wire body 13 is installed at the middle portion of the right end of the relay body 10, a current transformer 11 is sleeved and installed in the middle portion of the outgoing wire body 13, and the current transformer 11 is installed on the rear seat wall of the base 1, an outgoing wire conductive sheet 12 is installed at the right end of the outgoing wire body 13, a relay lower contact 101 and a relay upper contact 102 are installed at the upper portion of the right end of the relay body 10, and the relay lower contact 101 is located below the relay upper contact 102; the right portion of the outer surface of the outgoing wire body 13 is set as the outgoing wire lower end 131, and the left portion of the outer surface of the outgoing wire body 13 is set as the outgoing wire upper end 132; the right end of the outgoing wire lower end 131 is welded to the left end of the outgoing wire conductive sheet 12, the top of the outgoing wire upper end 132 is welded to the lower end of the relay lower contact 101, and the outgoing wire conductive sheet 12 is set as an L-shaped structure.
[0038] Through the above scheme: the circuit breaker is divided into an input port and an output port, and the line can be input from the input terminal block 8 and then output from the output terminal block 7, and fixed by the output terminal screws 5 and the input terminal screws 6. The whole structure is controlled by taking the relay body 10 as the main circuit of the main breaking circuit. The right side is the control communication circuit, and the current, voltage detection and temperature detection are added. It can measure and detect the electrical parameters of the terminal user, and can also be used for temperature detection, communication of electrical parameters and data transmission. Since the performance indicators of electrical parameters and power safety are collected, communication and data upload can be carried out through RS485, which is more intelligent, thereby integrating control, over-voltage and under-voltage, current detection, voltage detection, voltage feedback, electrical parameter data analysis and transmission, which can give the circuit breaker a more intelligent use and improve the comprehensiveness of the circuit breaker function.
