Product Description

Introduction

The soft starting device is used to control the starting of high-voltage AC motor. Its main composition is the three-phase anti parallel thyristor assembly and its electronic control device connected between the power supply and the  controlled motor. SHVSF series high-voltage solid-state soft starting device is composed of multiple thyristors in series and parallel. The output voltage is   controlled by controlling the trigger angle of thyristors, which can meet the   requirements of different voltages and currents during motor starting. In the   process of motor starting, SHVSF series high-voltage solid-state soft starting  device increases the terminal voltage of the motor according to the preset  starting curve to make the motor accelerate smoothly, so as to reduce the electrical and mechanical impact of motor starting on power grid, motor and connected equipment. When the motor starts up to the normal speed, the bypass  vacuum contactor or circuit breaker is connected, and the motor starts up. During the operation of the motor, the soft starting device continues to monitor the motor, measure the motor current and voltage in real time, and provide various relay protection functions.
