Abstract

The invention relates to a mutual inductor for a rectifier type low-voltage circuit breaker. The mutual inductor comprises an equipment box, wherein a box cover is arranged on the equipment box, and a plug-in type circuit board is arranged in the equipment box. The mutual inductor is characterized in that data interfaces are arranged on the plug-in type circuit board, data wires are arranged between the data interfaces, a processing device and a storage device are connected to the data interfaces, a tripping gear is connected to a control port of the processing device, a display device is connected to a data output port of the processing device, and an external mutual inductance device is connected to the outside of the equipment box through a main connecting component. In this way, functional circuits such as the rectifying circuit of the mutual inductor can be effectively moved outwards, and the structure is made more reasonable; furthermore, favorable conditions are created for intelligent controller function integration and structure miniaturization, protective reliability of the circuit breaker is better, and power grid accidents are avoided. Moreover, the mutual inductor is simple in structure and easy to manufacture and assemble.

Description

technical field [0001] The invention relates to a mutual induction device, in particular to a mutual induction device for a rectifying low-voltage circuit breaker. Background technique [0002] The circuit breaker is mainly used in the AC power grid, and the voltage generated by the secondary induction of the transformer is also AC, so there is a need to rectify the secondary induced voltage before it can be provided to the intelligent controller for various DC working power supplies required for voltage stabilization. With the development of functional integration and miniaturization of circuit breakers and intelligent controllers, the space for intelligent controllers used in circuit breakers has become increasingly narrow. [0003] However, the existing transformers cannot realize the effective rectification function, and the output voltage of the transformer needs to be rectified and stabilized by measuring instruments, protective equipment, etc. before it can be used, w...
