YDQ series low voltage squirrel cage motor electro-hydraulic starter

Overview
_
_
Series of low-voltage squirrel-cage motors and synchronous motors liquid resistance soft-start device
is developed for the starting and operation of low-voltage squirrel-cage motors and synchronous motors developing. Solve the problem of smooth soft starting of AC, rated working voltage and rated power ~ AC squirrel cage asynchronous and synchronous motors.
Main performance features
The device has small starting current, smooth starting process, no impact on the motor, load and power grid, and no harmonic pollution to the power grid.
The device can add an automatic water replenishing function, that is, before the motor is soft-started, the system will automatically detect the liquid level of the electrolytic tank. The water replenishing device will automatically maintain the liquid level of the liquid resistor at the set height, avoiding the need for users to No need to worry about regularly checking the liquid level and manually adding water (this function is an additional function and needs to be listed separately when ordering).
Scope of application
Suitable for three-phase AC asynchronous motors with rated working voltage and rated power in metallurgy, petroleum, chemical industry, building materials, municipal engineering, light industry, mining and other industrial fields. Soft starting and main loop control of synchronous motors.
Environmental conditions for use
The maximum ambient temperature is +℃, the minimum temperature is ℃
The daily average relative humidity does not exceed, and the monthly average does not exceed (+℃)
The altitude does not exceed
/> The inclination of the ground does not exceed
The installation location is free of fire, explosion hazard, chemical corrosion and severe vibration
Note If there are special conditions of use, please declare and negotiate with our company when ordering.
