HSV high voltage solid state soft starter

1. Product Overview
Our company produces a series of solid-state soft starting devices for medium and high voltage motors (hereinafter referred to as soft starting devices)
which are mainly suitable for squirrel-cage asynchronous and synchronous motors. Start and stop control and protection. It uses high-quality series-parallel thyristors to steplessly control the output voltage and enable the motor to start and stop smoothly. It has fault protection functions such as overload, phase loss, and operating overcurrent. It can effectively avoid harmful impacts on the power grid caused by excessive motor starting current, and can normally use high-power motors under limited power grid capacity and extend their service life. service life.
Series soft starting devices are suitable for soft starting of large and medium-sized AC motors with rated voltage
. The products are widely used in large-scale steel, petroleum, chemical industry, aluminum industry, fire protection, mining, sewage treatment, electric power and other industrial fields, and can be used well with electric motor driving equipment. Such as water pumps, fans, compressors, pulverizers, mixers, belt conveyors and other electromechanical equipment.

3. Working principle
The thyristor high-voltage soft starting device is actually connected in series between the three-phase AC phase voltage and the three-phase AC asynchronous ( and synchronization) between the motor input terminals. By simultaneously adjusting the delayed conduction angles of three independent anti-parallel thyristor valve assemblies, the AC input voltage amplitude of the three-phase asynchronous motor (and synchronous motor) is changed, thereby changing the effective value of the three-phase input AC current. Achieve the purpose of constant current starting or starting or stopping according to a certain slope change curve. When starting is completed, the three-phase bypass contactor automatically closes and the motor is put into grid operation.
