High -voltage dry starting electric antibody
When starting the AC asynchronous motor under the rated voltage, the initial starting current is very big and usually several times of the rated current (5-7 times in normal cases). To reduce the starting current and not affect the grid, the AC asynchronous motor is usually started by reducing the voltage. Voltage is usually reduced by using the reactor or the auto-transformer. The start process of the AC motor is very short (from several seconds to two minutes in normal cases). After it is started, the reactor or auto-transformer used for reducing the voltage will be removed. This product is designed according to the start characteristics of high voltage asynchronous motor.

The discharge coil is used to connect with high-voltage parallel capacitors in the power system, allowing the remaining charge of the capacitor bank to be quickly discharged after being cut off from the power system. Therefore, installing discharge coils is a necessary technical safety measure for parallel capacitors in substations, which can effectively prevent overvoltage and overcurrent that endanger equipment safety when the capacitor bank is closed again due to the fact that the capacitor still carries charge, and ensure the safety of maintenance personnel. It can be equipped with secondary windings for line monitoring, monitoring, and secondary protection.
