Large high-voltage motor starting device

The invention discloses a large high-voltage motor starting device which comprises a dry type electric reactor, a plurality of integrated capacitors, a circuit breaker and a PLC controller, where thecircuit breaker is used for connecting a high-voltage motor with a power circuit breaker of a power supply and switched integrated capacitors, the PLC controller has a logic programming function, thedry type electric reactor can reduce machine end voltage of the high-voltage motor, the integrated capacitors are used for compensating reactive power required by starting the high-voltage large motor, and the integrated capacitors are controlled by the PLC; the dry type electric reactor is divided into a plurality of dry taps, and the dry taps can be adjusted according to power grid capacitance change; the integrated capacitors can be divided into a plurality of groups and further can be switched at will. The large high-voltage motor starting device has the characteristics of simple structure, convenience in maintenan
