Technical field
The utility model relates to a kind of switch controlling device, particularly a kind of remote control device of contact line high voltage isolator.
Background technology
High voltage isolator is device for switching important in power plant, transformer station, railway contact line electrical system, and its major function ensures High-Voltage Electrical Appliances and the safety of device when service work, plays isolation voltage.The rotating that isolator operating mechanism mostly adopts the electric component such as contactor, relay to realize motor switches the order of Long-distance Control divide-shut brake and triggers motor-operating mechanism with burst pulse, motor-operating mechanism is provided with self-holding circuit, action completes automatically, so realize isolating switch deciliter.Remote control command adopts Optical Fiber Transmission mode, and conventional optical fiber control mode malfunction, tripping, by mistake display fault happen occasionally, and make railway contact line power supply-distribution system there is potential safety hazard.The motor-operating mechanism of isolating switch disclosed in prior art adopts a road power supply and Long-distance Control circuit composition.Control circuit only gives signal a--burst pulse of divide-shut brake, and rotating and the functions such as stopping that putting in place of motor-operating mechanism all complete in motor-operating mechanism inside.Control circuit that is very large due to high-speed railway high order harmonic component, motor-operating mechanism is very long, control impuls is very narrow, the malfunction therefore often having clutter to sense in control circuit to cause motor-operating mechanism, tripping, by mistake display.In order to overcome the defect that existing motor-operating mechanism exists, be badly in need of a kind of electric operating means.
Summary of the invention
The purpose of this utility model is to provide a kind of electric controller of isolating switch, solves the malfunction of existing electric controller, tripping, by mistake display problem.Achieve position-detection sensor and directly control heavy current, decrease controlling unit, improve the reliability of control.
The utility model is the improvement on the electric controller basis of existing isolating switch.Concrete, the electric controller of a kind of isolating switch that the utility model provides is made up of motor, decelerator and two groups of action actuating mechanisms.Motor drives axis of rotation by decelerator, rotating shaft is located at the centre of two groups of action actuating mechanisms, rotating shaft one end is provided with connector, for being connected with high voltage isolator, action actuating mechanism comprises fixing miniature air circuit breaker on the supporting plate, the supporter be fixedly connected with supporting bracket is provided with guide pillar, guide rod is provided with in the middle of the slide block be slidably matched with guide pillar, lower end of the guide rod is equiped with back-moving spring, slide block one side is provided with the plate for driving the micro-disconnected shift fork of miniature air circuit breaker to turn off, vertically with supporter to fix, and the top of the limited screw be connected with skid is provided with spacing head, the spindle nose of rotating shaft is provided with the shifting block being fastenedly connected with rotating shaft and protruding from axle side, shifting block presses with the guide rod in the middle of slide block and coordinates.
The course of work of electric controller of the present utility model is such.Motor drives axis of rotation by decelerator, shifting block in rotating shaft together rotates with rotating shaft, when the shifting block in rotating shaft rotates to the slider waveguide rod on the action actuating mechanism of contact side, under the effect of shifting block pressure, guide rod band movable slider moves down along guide pillar, and the plate of slide block side dials the micro-disconnected shift fork on lower miniature air circuit breaker in folding process simultaneously, make it disconnect, cut off motor power, electric controller stall, rotating shaft one end connector controls high voltage isolator and closes.To motor with reverse rotation instruction, the plate on slide block moves up along guide pillar under the elastic force of back-moving spring with slide block, and the micro-disconnected shift fork that plate is stirred on miniature air circuit breaker closes.Shifting block in rotating shaft continues to rotate, until the miniature circuit breaker on the action actuating mechanism of opposite side disconnects, cut off motor power, mechanism has reversed, thus realizes the object controlling electric controller.
Electric controller of the present utility model is the control realizing mechanism by controlling motor circuit, and therefore antijamming capability is strong; Adopt the limit switch with disjunction load-bearing capacity, can be easy to realize control logic.This electric controller divides duplex feeding, a road drive motors main story, a road drive motors reversion.Two-way electricity is by two miniature air circuit breaker parallel connection access motors.After isolating switch folding puts in place, electric controller disconnects micro-disconnected shift fork by plate and makes motor stalling, reaches the object that electric controller drives the accurate start and stop of isolating switch.The remote control unit of isolating switch electric controller and control and protection unit all adopt indoor layout, do not arrange electric protective device separately in mechanism case.In order to avoid motor rotation blockage causes miniature circuit breaker to trip, circuit breaker tripping electric current is much larger than the rated current of motor, and indoor control and protection unit preferentially starts, to reduce field maintenance workload.Effectively can solve isolating switch malfunction, tripping, by mistake display problem like this.
The electric controller of isolating switch of the present utility model is particularly useful for the control of applied to high-speed railway touching net electric isolating switch, achieves applied to high-speed railway touching net high-voltage electric isolating switch telemechanical and directly controls.Solve the fault such as isolating switch malfunction, tripping, by mistake display, reduce the failure rate of railway power supply-distribution system, for high-tension line action stability provides safeguard.
The beneficial effect that the utility model obtains is as follows: this electric controller can easily realize high voltage isolator telemechanical direct control scheme.Solve the fault such as isolating switch malfunction, tripping, by mistake display, be particularly useful for the control of applied to high-speed railway touching net electric isolating switch, reduce the failure rate of railway power supply-distribution system, for high-tension line action stability provides a favorable security.
