Thyristor solid medium voltage soft starter

I. Overview In our country's coal mine, petroleum, chemical industry, steel, power generation, water supply, cement building materials and other fields, there are a large number of 3KV, 6KV, 10KV and other voltage levels of medium and high voltage AC asynchronous motors. A large part of them do not require speed regulation, but need to solve the starting problem of these high-voltage large motors.
