Power is strong；Using the limit switch with disjunction load-bearing capacity, control logic can be easily achieved.The electric controller is divided to two
Road powers, all the way motor main story, all the way motor reversion.Two-way electricity passes through the access in parallel of two miniature air breakers
Motor.When disconnecting switch folding in place after electric controller micro- disconnected shift fork disconnected by plate stall motor, reach electronic
Control device drives the purpose of the accurate start and stop of disconnecting switch.The remote control unit of disconnecting switch electric controller and control are protected
Shield unit uses indoor arrangement, and electric protective device is not separately provided in mechanism case.In order to avoid motor rotation blockage cause it is miniature
Circuit breaker trip, circuit breaker tripping electric current are much larger than the rated current of motor, and indoor control and protection unit preferentially starts, to reduce
Field maintenance workload.So can effectively solve solve disconnecting switch malfunction, by mistake tripping, display problem.
Control of the electric controller of the disconnecting switch of the present invention particularly for high-speed railway touching net electric isolating switch
System, realizes high-speed railway touching net high-voltage electric isolating switch telemechanical and directly controls.Solve disconnecting switch malfunction, tripping,
The failure such as display by mistake, the fault rate of railway power supply-distribution system is reduced, provided safeguard for high-tension line action stability.
What the present invention obtained has the beneficial effect that：The electric controller can easily realize that high voltage isolator telemechanical is straight
Connect control program.Solve disconnecting switch malfunction, tripping, by mistake display etc. failure, particularly for high-speed railway touching net it is electronic every
The control of pass is left, reduces the fault rate of railway power supply-distribution system, is provided a favorable security for high-tension line action stability.
