Description
Technical field
The invention belongs to technical field of electric equipment, specifically, particularly relate to a kind of novel energy-conserving high breaking type control and protective switch.
Background technology
Control and protective switch is a kind of intelligent device for switching functions such as short-circuiting device, contactor, thermal relay rolled into one; be mainly used in the occasion needing to protect motor, major function has: short-circuit protection, open phase protection, rotation-clogging protection, overcurrent protection, overvoltage/undervoltage protection and earth leakage protective.The structure of this kind of switch on existing market mainly comprises following parts: major loop contact terminal system, electromagnetism adhesive system, fault trip system, signal acquiring and processing system.Switch on and off has been come with release by the adhesive of alternating electromagnet, when having there is short circuit current in running, instantaneous coil produces enough large magnetic field and pulls iron core to make mechanism be transformed into trip positions, driving lever in mechanism makes the contact of electromagnetism pull-in winding disconnect and makes its power-off, electromagnet discharges, and major loop contact terminal is disconnected.There is following defect in the switch of this structure of tradition:
1. occur to major loop from short circuit current to disconnect, middle link is many, and the time is long.Because short circuit current very large, longer break-time will produce very large damage to contact, even causes the adhesion of contact;
2. drive the instantaneous coil of short circuit instantaneous trip mechanism, add the length of switch internal current-carrying part, become a main pyrotoxin of switch internal, reduce the electrical efficiency of switch, and the extinguishing of the inductive load characteristic of coil electric arc when being unfavorable for switch disjunction, add the loss of contact;
