As being assessed in real time, and main control unit is notified to execute necessary hedging movement.
The principle of the present invention is:
(1) monitoring and protecting function
By the monitoring to height pressure side Current Voltage, the influence of over-voltage and over-current lacuna and impact is guarded against, while monitoring high-low pressure
Hold operating status.The variation that can be occurred with dynamic monitoring step down side voltage, electric current, when necessary cutting system.Low-pressure side
The monitoring of monitoring device low-pressure side can also judge high-pressure side operating status, when any phase of high voltage side of transformer or two-phase fuse, energy
Low-voltage circuit breaker cutting load is controlled, no-load transformer is run.This method controls the superior height of service performance in high-pressure side
Vacuum contactor is pressed, the on-off by controlling voltage switch, which is realized, controls transformer.Low-pressure side installs controllable breaker.This
Simultaneously in view of protecting and using safely to high-pressure vacuum contactor in method.
(2) bilateral combines on-off
Take the measure to low pressure side and high pressure side while control.High-pressure side delays time to control is first opened in system control process to open again
Low-pressure side first closes low-pressure side delays time to control and closes high-pressure side again.During switching on and off, protection low-pressure side high pressure connect and
It disconnects the high voltage surge that moment generates and impact is generated to low-pressure side, meanwhile, guarantee that high-voltage switch gear is impacted without high current in high-pressure side.
(3) Energy Saving Control
Energy Saving Control mainly prevents transformer waste of energy due to zero load.Such as street lamp and the isallobaric device correlation control of urban landscape
System.Street lamp and urban landscape can be automatically closed daytime, and at this time transformer is just unloaded, and accumulating over a long period, it is big to be lost.Same farmland water
It works when sharp summer or arid, other times do not work, and the relevant no-load transformer time is long, and no-load loss is big.This method is logical
Cross acquisition photosignal, time signal and electric current, voltage signal judges and control transformer on-off, reduce no-load transformer,
Energy conservation.
