Medium Voltage Soft Starter is a high voltage motor soft starter designed with up-to date concept, mainly applicable to the control of and protection for the starting and stopping of squirrel-cage type asynchronous and synchronous motors. The starter is composed of several thyristors in series-parallel, and it can meet different current and voltage requirements.
The product is widely used in electric industry with rated voltage 3000 to 10000V, building materials chemical industry,
metallurgy, steel and paper-making industries etc., and can perform well if used together with various kinds of
electromechanical devices including water pumps, fans, compressors, crashers, agitators and conveyer belt etc., It is the
ideal device for starting and protecting high voltage motors.
1. Free of maintenance: Thyristor is an electric device without contacts. Different from other kinds of products that need
frequent maintenance on liquid and parts etc., it turns the mechanical lift into the service life of electronic components, so it needs no maintenance after running for many years.
2. Easy installation and operation: A complete system for controlling and protecting the starting of motor. It can put into
operation only with the power line and motor line connected. The whole system can be tested electrically under low voltage before operating with high voltage.
3. Backup: The starter comes equipped with a vacuum contactor which can be used to start the motor directly in the inside.If fails, the vacuum contactor can be used to start the motor directly to ensure the continuity of the production.
4. High voltage thyristor is a component of major loop, equipped with voltage balancing protection system and over-voltage protection system.
5. Comes equipped with an electromagnetic blocking device for fear of entering the high voltage device in the electrified
state.
6. Advanced optical fiber transmission technique realizes the triggering detection of high voltage thyristor and the isolation between ontrol loops.
7. DSP microcontroller is used to perform central control which is real-time and high efficient with high reliability and excellent stability.
8. LCD/touch screen display system in both Chinese and English with human-friendly operation interface.
9. RS-485 communication port can be used to communicate with the upper computer or centralized control center.
10. Aging experiments are made on all circuit boards.
