Abstract

An electromagnetic residual current action protector mechanism. The parts are layered and distributed between the base and the pressure plate in a tree shape. The parts are covered by the pressure plate and fixed by tightening the screws. The base and the pressure plate are connected by a main shaft, and the mechanism parts surround the main shaft. turn. The turntable is placed on the two steps of the base, and the jumper and the turntable can only act when they are under the force of the spring. At the same time, the turntable will not cause the entire mechanism to tilt due to the force of the spring, which will affect the assembly. The mechanism guarantees the reliability of its action through force transmission and amplification during the tripping and closing process. The reset part and the turntable adopt the form of overlapping grooves to ensure that the mechanical life of the mechanism is not affected. The output force of the mechanism directly comes from the turntable , does not need to be transmitted, preventing the loss of force and ensuring the reliability of linkage.

Description

technical field [0001] The invention relates to an electrical protection mechanism, in particular to a residual current action protection mechanism with high reliability and high operability. Background technique [0002] In the mechanism of residual current operated protector, in addition to high reliability, high operability is also required. Most of the current residual current-operated protector mechanisms are integrated, and the parts are widely scattered. The production process requires more technological equipment, poor operability, repairability, and low utilization rate. Contents of the invention [0003] The purpose of the present invention is to provide an electromagnetic residual current operating protection mechanism which not only overcomes many shortcomings of the existing residual current operating protection mechanism, but also has high reliability and high operability. [0004] According to the technical solution provided by the present invention, a cyli...
