AI Technical Summary

Technical Problem

When existing single-pole contactors are superimposed for multi-loop control, there are problems such as high cost, large space occupation and poor sealing performance. In addition, when one pole fails, the other pole cannot conduct, which poses a safety hazard.

Method used

By improving the structure of the single-pole single-throw contactor and using a circuit board to control the dual coils, the rotation and direct motion of the moving iron core are realized, which in turn drives the rotation and direct motion of the contacts. Combined with the magnetic holding system and the transmission system embedded in the arc-extinguishing chamber, only the excitation source and the magnetic conductive parts are external, thus realizing the 'single-pole double-throw' function and improving the sealing performance.

Benefits of technology

It reduces the space occupied by multi-pole contactors, solves the safety hazards caused by single-pole failure, and improves the sealing performance of contactors.

Abstract

A kind of control switch, the contact of movable contact piece (101) of movable contact system (1) and the contact and separation of corresponding static contact group (2) realize the on and off of contactor, it is characterized in that: the movable contact system (1) is connected with direct-acting drive magnetic system (3), rotary drive magnetic system (4) is connected with the movable contact system (1) by transmission system (5), the rotary drive magnetic system (4) can drive the movable contact system (1) rotation by transmission system (5), the direct-acting drive magnetic system (3) can drive the movable contact system (1) direct-acting.The existing single-blade single-throw contactor structure is improved, to realize the "single-blade double-throw" function of single moving iron core and single moving contact, reduce the space occupied by multi-pole contactor, single moving contact also solves single-pole failure, while effectively improve the sealing performance of contactor.
