浅谈电力拖动控制中的Δ形与Y形连接

Discussion on the Δ and Y of Electric Drive Control

在电力拖动控制中常常遇到Δ形连接与Y形连接。本文从Δ形与Y形连接的关系、在降压起动控制中的运用、可能出现的故障进行了分析,以便在实际应用的过程中加以利用,防止意外发生。

Δ and Y connection is widely used in the power supply system.It often encounter in the electric driving control.This article analyzed the possible fault from the Δ and Y shape connection relationship,the reduced voltage starting control,so that it can use in the practical application,and prevent the accident.
