Centralized control device of pressure regulating can carry out

The utility model provides a centralized control device of pressure regulating can carry out, this centralized control device include input voltage terminal, transformer, pressure regulating contactor, circuit breaker, circuit breaker warning contact, rectifier bridge, protection device, the control power supply terminal that connects gradually through the cable. The utility model discloses an effect adopts this voltage regulation control apparatus, and it providing different magnitude of voltages to the mechanism of same distance not to realize, has avoided having avoided burning of motor or refusing of isolator because the power supply voltage deviation makes the operating condition who owes the electricity that is in far away long -term again of mechanism. And the pressure regulating control of adopting not the same distance to provide different voltages can guarantee that the power supply voltage deviation is rated voltage's - 9 percent~3.7 percent, has improved 11 percent according to the far and near adjustment power supply voltage of distance for power supply voltage is stable, and is less with the rated operational voltage deviation, can work in the higher environment of security performance.
