Abstract

This invention relates to one switch multi-electrode circuit device, which comprises one switch parts and is characterized by the following: matching the switch host circuit switch parts with triggerprobe changed into two different circuits through two positions to realize motor reverse, double direction, star angle, double power conversion or double speed operation control; conversion probe andcontrol electromagnetic iron and its control circuit distributed along the switch device and its matched switch to reduce switch device size. The switch device comprises conversion probe and its conductive loop, print circuit board and cable system.

Description

Technical field: [0001] The invention relates to a switch device for switching a multi-pole circuit, more precisely relates to a switch device used for a multi-pole switching device, and belongs to the field of electric technology. Background technique: [0002] At present, the reversible, two-way, star-delta or two-speed control of motors at home and abroad often adopts at least two control and protection switchgears, two contactors or two other switchgears with electrical interlock and mechanical interlock. achieve, see Figure 1a shown. [0003] This type is also often used for dual-power conversion switching appliances composed of separate devices, that is, two control and protection switching appliances, two contactors or two circuit breakers are implemented by adding electrical interlocks and mechanical interlocks, see Figure 1b shown. [0004] For example, patent ZL 01238478.X discloses a switching device for controlling and protecting a motor, which can realize re...
