Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1-2, this utility model provides a kind of technical scheme: a kind of device in one-way on state, including main body 101,
Motor-operating mechanism 102, off-state travel switch 103, closure state travel switch 104, the first disconnecting switch 105, rectification
Diode 106, device in one-way on state controller 107, IGCT 108, the second disconnecting switch 201, motor-operating mechanism 202, OK
Journey switch closed position auxiliary contact 203, travel switch open position auxiliary contact 204, controller 205 and long distance control system
206, motor-operating mechanism 102 is the first disconnecting switch 105 sets up a travel switch open position auxiliary contact 204,
Travel switch open position auxiliary contact 204 access controller 205, controller 205 is by travel switch make position auxiliary contact
203, travel switch open position auxiliary contact 204 state is sent to long distance control system 206, monitors the first disconnecting switch 105
State.After staff remotely sends shutoff or close command, cannot know what whether the first disconnecting switch 105 responded
In the case of, staff can pass through travel switch make position auxiliary contact 203, travel switch open position auxiliary contact 204
State learn the switching state that the first disconnecting switch 105 determines, once break down, as neither in logical state the most not disconnected
State, staff can rush towards scene in time and is operated manually or keeps in repair, eliminate safe hidden trouble, and what raising ran can
By property, at the scene in practical operation situation, diode generation reverse breakdown in device in one-way on state or flow through electric current and exceed and be
When system rated current makes fastp-acting fuse fuse, after controller 205 detects fault, controller 205 is to long distance control system 206
Send alarm signal, in order to disconnecting switch of closing in time 201 makes insulation knot two ends rail short circuit, does not affect the normal fortune of locomotive
OK, and overhaul.Long distance control system 206 by controller 205 after motor-operating mechanism 202 sends close command, electricity
Pneumatic operating mechanism 202 action, makes disconnecting switch 201 close, and travel switch make position auxiliary contact 203 closes, disconnecting switch
201 closure signal are uploaded to long distance control system 206 by controller 205；After locomotive passes through, disconnecting switch 201 needs to disconnect,
Long distance control system 206 sends open command by controller 205 to motor-operating mechanism 202, and motor-operating mechanism 202 moves
Making, make disconnecting switch 201 disconnect, travel switch open position auxiliary contact 204 closes, and disconnecting switch 201 cut-off signal passes through
Controller 205 is uploaded to long distance control system 206.By remotely operation, long distance control system 206 can accurate measurements disconnecting switch
The switching state of 201.When motor-operating mechanism 202 breaks down, long distance control system 206 sends point, after order of closing a floodgate,
Not monitoring the status signal of disconnecting switch 201, staff isolates according to travel switch auxiliary contact 203,204 condition adjudgement
Switch 201 operation failures, corresponding measure can be taked to solve problem, eliminate safe hidden trouble, it is ensured that the normal fortune of device in one-way on state
OK.
