Abstract

The invention discloses a circuit breaker. The circuit breaker comprises a shell; wherein a wire inlet mechanism and a wire outlet mechanism are arranged in the shell and are located at the two ends in the shell respectively; a tripping device is arranged in the shell and is positioned between the wire inlet mechanism and the wire outlet mechanism; a switching-off and switching-on execution mechanism is arranged in the shell, works in cooperation with the tripping device and is used for realizing switching-off and switching-on operation; the switching-on system is arranged in the shell, is positioned on the left side of the wire inlet mechanism and is used for driving the switching-on and switching-off execution mechanism to execute switching-on operation; and the arc extinguishing systemis arranged in the shell and is positioned below the tripping device. The circuit breaker provided by the invention is simple to assemble, compact in structure, high in integration level, small in size and highly integrated in function.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a circuit breaker. Background technique [0002] Circuit breakers are common circuit protection devices. The internal layout of the existing general circuit breaker is as follows: the magnetic trip part, the thermal trip part, the operating mechanism part, and the arc extinguishing part are arranged in a fixed space. If other intelligent functions are added, such as active control of opening and closing, For functions such as leakage protection, metering, overvoltage, undervoltage, and overtemperature detection, it is often necessary to increase the volume of at least two modules, resulting in a larger overall volume of the circuit breaker and complicated assembly processes. However, due to the relatively large overall volume of the existing circuit breaker, it occupies a large space in the limited space of the distribution box, and cannot effectively utilize the intern...
