1. Basic Principle

The TCQY Series Medium and High Voltage Switchgear Magnetron Soft Starter Integrated Cabinet is mainly used for the control and protection of starting and stopping squirrel-cage asynchronous motors and synchronous motors. It utilizes a new generation of autotransformer excitation soft start patent technology to successfully develop a new type of solid-state soft starting device, suitable for starting large, medium-sized, and particularly large squirrel-cage or synchronous motors.

By inserting a self-excited controllable reactor with a smoothly variable impedance into the stator circuit of the squirrel-cage or synchronous motor, the closed-loop control system automatically adjusts the size of the DC current in the self-excited controlled winding (without the need for an external high-current power source). The impedance of the self-coupling excited controllable reactor automatically decreases steplessly from high to low within a predetermined time, gradually increasing the motor terminal voltage to full voltage, thereby achieving a soft start for the motor.

2. Performance Features

◆ Different starting current curves such as constant current, ramp-up, and jump-start can be selected according to the requirements of different working conditions.

◆ Use internationally leading computer simulation technology, making the entire starting process predictable, controllable, and adjustable.

◆ User-friendly interface, convenient for setting, adjusting, and querying starting parameters.

◆ High safety and stability, long service life.

◆ Good reusability, starting performance unaffected by ambient temperature.

◆ High degree of automation, easy operation, capable of soft stopping.
