NRRQV series high-voltage solid-state soft starter device

Product overview

The NRRQV series high-voltage solid-state soft start device (hereinafter referred to as the soft start device) is a soft start device of the high-voltage motor designed with the latest concept, which is mainly suitable for the start-stop control and protection of the rat cage asynchronous motor and the synchronous motor.The device uses a polythyristor in series and can meet different current and voltage requirements.three-phase 50Hz.Rated voltage is 0.4kV, 3KV, and 6KV.10 kV.Rat cage asynchronous (synchronous) motor, rated at 100 to 30,000 k W, is suitable for various loads.

The products are widely used in power, building materials, chemical, gold steel and paper industries with rated voltage of 3000-15000V.It can be used with water pump, fan, compressor, grinder, mixer, belt machine and other mechanical and electrical equipment.It is the ideal starting and protection equipment for high voltage motor.

The soft start device configuration: divided into two structures: superior motor outlet cabinet, motor start cabinet cable to soft start cabinet, soft start cabinet cable to motor.Integrated high-voltage solid-state soft start cabinet, switch cabinet and soft start integrated in a switch cabinet, small volume, convenient installation, can be installed together with other switchgear.
