Up to now, Xichi Electric has developed the following products to improve power quality. The voltage level of the product covers 0.38/0.48/0.69/1.14kV, including active and passive, and has comprehensive power pollution control functions such as harmonic control, reactive power compensation, unbalance compensation, voltage compensation, and combination compensation of various functions.

1. First, confirm whether the motor is a squirrel-cage asynchronous motor.Asynchronous motors (also known as induction motors) are divided into squirrel-cage type and wound type according to the rotor structure. Soft starters are mostly suitable for asynchronous squirrel-cage motors. 2. Understand the parameters on the motor nameplate. For example, the model of the motor, rated current, rated power, etc. Generally, the capacity of the soft starter is slightly larger than the working current of the motor.

The digital intelligent motor soft starter has a variety of starting and stopping methods. Users can choose the appropriate mode according to the load and specific use conditions.Starting methods: current limit start, voltage ramp start, current ramp start; Stopping methods: free stop, soft stop, brake stop, soft stop + brake stop. Xichi CMC-HX motor soft starter has a variety of starting and stopping methods.

l It can realize any combination of three functions of harmonic control, reactive power compensation and three-phase unbalanced current adjustment.l The priority of each function can be set according to the load environment and demand to achieve multi-compensation for power quality problems. l The s

l Divided by the way of transmission:：a. Radiation interference b. Conducted interference l Anti-interference measures: n For the interference signal transmitted by radiation, it is mainly weakened by wiring and shielding the radiation source and the line to be interfered. n For the interference sig

Overload protection function: The soft starter introduces a current control loop, so it can track and detect the change of motor current at any time. By increasing the setting of overload current and the inverse time limit control mode, the overload protection function is realized. When the motor is

Complete sets of electrical appliances are widely used in power plants, substations, industrial and mining enterprises, high-rise buildings and other places where electricity is used. 1. In the low-voltage power distribution system, low-voltage power distribution devices in substations use low-volta

Note: Before maintenance and inspection, all power sources on the incoming side of the power controller must be cut off.1. If the power indicator light is off, please check whether the control power is connected normally. 2. The main circuit has no output (1) Check whether the input voltage of the m
