Abstract

The invention particularly relates to an electromagnetic switch capable of switching delta-shaped and Y-shaped connection modes. The electromagnetic switch can change wiring methods for a motor. The electromagnetic switch comprises a shell, wherein one end of the shell is provided with three terminal blocks. The electromagnetic switch is characterized in that: two tripolar electromagnetic switch mechanisms are arranged in the shell; and the three input ends of each tripolar electromagnetic switch mechanism are connected with three input terminals respectively. The electromagnetic switch overcomes the shortcomings of troubles in mounting and wiring and high cost of the prior art in which the delta-shaped and Y-shaped connection modes of the motor are switched by an AC contactor, and has the advantages of low cost, mounting and wiring simplicity, and stable and reliable performance.

Description

technical field [0001] The invention specifically relates to an electromagnetic switch for changing the connection mode of a delta-shape and a Y-shape for changing the wiring method of a motor. Background technique [0002] Motor power saving usually adopts the method of mutual conversion between △-shaped connection and Y-shaped connection. The realization method is to use two AC contactors to switch each other, which is troublesome and costly to install and connect. It is easy to burn out when the voltage is high, and the contactor works unstable when the peak voltage of power consumption is low, which affects the reliability of the motor. Contents of the invention [0003] The purpose of the present invention is to solve the defects of cumbersome installation and wiring and high cost in the prior art of using an AC contactor to convert the △-shaped and Y-shaped connection mode of the motor, and to provide a △-shaped motor with simple installation and wiring, low cost and...
