智能电机控制器在消防水系统上应用的电路设计

Intelligent Motor Controller in the Fire Water System Application of the Circuit Design

为了减小电机在启动时对电网产生的压降,同时对电动机实施过载、失速、堵转、欠压、过压、电压不平衡保护,采用智能电机控制器控制电动机,设计了一块可以设定高低压值的电接点压力表控制智能电机控制器。

In order to reduce the voltage drop generated by the motor during start-up and apply overload,stall,locked-rotor,undervoltage, overvoltage,and voltage unbalance protections to the motor,an intelligent motor controller is used to control the motor. An electric contact pressure gauge that can set high and low voltage values is designed to control the in lligent motor controller.
