Abstract

The invention provides a circuit breaker, and relates to the technical field of electrical equipment. The circuit breaker comprises a circuit breaker body and a voltage sampling structure, wherein the voltage sampling structure comprises a controller, a switching circuit board, a mutual inductor and at least one conductor; the conductors are respectively arranged in the shell of the mutual inductor in a penetrating manner, one end of each conductor extends out of the first side of the shell of the mutual inductor and is in contact and electrical connection with the switching circuit board, and the other end of each conductor extends out of the second side of the shell of the mutual inductor and is in contact and electrical connection with a power wiring end in the circuit breaker body; and the switching circuit board is in contact and electric connection with the controller, so that the controller samples and analyzes the voltage transmitted by the electric conductor and the switching circuit board. The electric conductor is arranged in the shell of the mutual inductor in a penetrating mode, the electric conductor is electrically connected with the switching circuit board and the electric power wiring end in a contact mode, the switching circuit board is electrically connected with the controller in a contact mode, arrangement of voltage sampling lines is reduced, the wiring structure is simplified, and the circuit breaker is more convenient to install and detach.

Description

technical field [0001] The present invention relates to the technical field of electrical equipment, in particular to a circuit breaker. Background technique [0002] Circuit breakers can be used to distribute electrical energy and protect power lines and motors. With the development of science and technology, circuit breakers have more and more functions, and circuit breakers with voltage acquisition functions are also widely welcomed. [0003] In the related technology, the voltage sampling line drawn from the controller of the circuit breaker is connected to the circuit board of the circuit breaker, and then the voltage sampling line drawn from the circuit board of the circuit breaker is connected to the power outlet terminal or the power input terminal, so as to realize the control of the circuit breaker controller. Voltage sampling analysis. [0004] However, in the related art, the wiring structure of the voltage sampling line is complicated, which makes it inconveni...
