Abstract

The invention relates to a bi-stable three phases AC relay that belongs to basic electric component especially relay. The technology problem is to supply a bi-stable three phases AC relay that is small volume and contact credibility. It is made up of control circuit, coil assembly, magnetic steel assembly, contact system and basic crust. Its feature is that the control circuit adopts striking transformer, silicon controlled rectifier, thick film integration module constituted by resistances that is embedded in the one end of the base crust next to coil assembly and the two ends of the relay coil is separately connected to the neutral line and phase conductor of AC power supply, driving rod that is set in the middle of the three couple main contacts and connected to the keyway of the containing body of magnetic steel assembly. The invention is suited for bi-stable three phases AC relay.

Description

Technical field:

[0001] The invention relates to basic electrical components, especially relays. Background technique

[0002] The existing relay is composed of a coil combination, a magnetic steel combination, a contact system and a base shell. The coil assembly is composed of coils, double yokes, and double short-circuit rings; the magnetic steel assembly is composed of a cylindrical shaft, magnetic steel, and an armature that are packaged in compression plastic; Three pairs of main contacts realize linkage. This kind of relay is driven by DC and equipped with an external transformer and electronic circuit. The overall volume is large, the efficacy is limited by the volume, and the reliability of the contact system is poor. When the relay is in a steady state, the transformer itself has static power consumption. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a bistable three-phase AC relay with small volume ...
