Towers, high voltage switch

Modern industrial production common electrical equipment, is a wide range of large strong electric switch, its working principle is to use alternating current flowing through the coil generates a magnetic field, electromagnetic suction contacts the contactor closes,  mcb circuit breaker  current loads (such as electrical motors, etc.) to power work. According to the working  power transformers  of AC contactor, when the AC  Voltage stabilizer  in the state retention, the AC current through the coil of the contactor will consume about tens of watts of energy consumption. Since China put into operation in large and medium-capacity AC contactor huge number, so the total annual energy consumption up amazing energy-saving technologies such contacts is to make contacts in the DC mode operation.
