Description
Technical field
The present invention relates to a kind of high voltage isolator, particularly relate to a kind of vehicle high-voltage isolation control circuit.
Background technology
Electric locomotive is to obtain electric energy from contact net, the locomotive driven with traction motor.Its electric energy by stream approach be
From contact net come 25kV single phase industrial frequence alternating current, through pantograph, high voltage isolator, main circuit breaker and main transformer A-X around
Group (winding X end receives the dead earth point on car body), flows into six moving axis by six ground connection refluxes, finally the most again
By Wheel Rail Contact to rail, rail return electric substation, finally realize the acquisition of electric locomotive electric energy.Every electric locomotive dress
Have two pantographs of before and after and two high voltage isolators, and high voltage isolator be just connected on pantograph and main circuit breaker it
Between, can realize corresponding pantograph branch road and main circuit breaker is switched on or switched off control.If a certain bow failure or connected
Roof high-pressure section when breaking down, can be by disconnecting the high voltage isolator of series connection with it, disengagement failure pantograph is propped up
Road, continues to locomotive operation by another pantograph, and therefore high voltage isolator is constitute electric locomotive circuit on side of overhead contact line one
Individual vitals.
The most harmonious series electric locomotive high voltage isolator uses ecp mode, compressed air end and high_voltage isolation
The gas circuit of switch connects, and locomotive control diagnostic system TCMS controls combined floodgate and separating brake, the high voltage isolator of high voltage isolator
Pantograph connect position (A) and be connected with pantograph, the main circuit breaker of high voltage isolator connects position (B) and main circuit breaker of railway engine company
Connect, disconnect position (C) and be connected with locomotive car body.For locomotives such as HXD3B, HXD3C and HXD3D, owing to net side High-Voltage Electrical Appliances are as main
In the High-Voltage Electrical Appliances cabinet that chopper, high voltage isolator, high voltage potential transformer etc. are installed between locomotive equipment, therefore high pressure
When disconnecting switch is in disconnection position, should ensure that coupled cut pantograph branch road is in ground state, it is to avoid should be by electricity
Bow branch road is under vacant state, and high-voltage fence sensing produces suspended voltage, brings harm to the personnel on car and equipment.
When combined floodgate electric pneumatic valve obtains electric, high voltage isolator is in operation position, and the pantograph that is i.e. connected connects with main circuit breaker；
When separating brake electric pneumatic valve obtains electric, high voltage isolator is in disconnection position, and the pantograph that is connected is connected with car body ground, it is to avoid produce the electricity that suspends
Pressure.
The sub-gate signal that TCMS sends finally to arrive high_voltage isolation open through the switching of the terminal such as terminal cabinet, high-voltage board
Close.Locomotive is under rising bow state, and once corresponding high voltage isolator separating brake electric pneumatic valve is owing to altering electricity or interference etc. by false triggering
Obtaining electric, and now pantograph cannot fall (the pantograph fall bow time was less than 5.5 seconds) in time, high voltage isolator will be arciform at liter
Being gone to disconnect position by operation position under state, cause contact net shorted to earth, the lighter's electrical network trip protection, severe one directly results in suspension,
The all running trains causing this section are late, have a strong impact on the normal utilization of railway.And control the rigid line of high voltage isolator
Being attached to control the outfan of device, this electricity of altering cannot be avoided with interference from software.
Summary of the invention
The present invention be directed to the deficiency of existing high voltage isolator, propose a kind of novel vehicle high-voltage isolation and control electricity
Road, is prevented effectively from locomotive under rising bow state, the electrical network tripping operation that causes due to high voltage isolator misoperation or blow electrical network etc.
Major accident, it is ensured that locomotive trunk railway properly functioning.
This vehicle high-voltage isolation control circuit, compressed air end is connected with the gas circuit of high voltage isolator, high_voltage isolation
The pantograph of switch connects position and is connected with pantograph, and the main circuit breaker of high voltage isolator connects position with main circuit breaker of railway engine even
Connect, disconnect position and be connected with locomotive car body, the sub-gate signal outfan of locomotive control diagnostic system and the inside of high voltage isolator
Time relay coil connect, external power supply is connected with separating brake electric pneumatic valve by time relay normally opened contact, locomotive control
It is provided with junction point between sub-gate signal outfan and the fall bow signal input part of diagnostic system, when locomotive control diagnostic system is sent out
When going out sub-gate signal, this signal is recycled to locomotive control diagnostic system input simultaneously as fall bow signal.
The invention has the advantages that: high voltage isolator sub-gate signal is controlling what high voltage isolator time delay disconnected for 5.5 seconds
Meanwhile, directly carry out fall bow and control (the normal locomotive fall bow time was less than 5.5 seconds), it is ensured that as long as locomotive carries out high voltage isolator
Disconnect conversion, be necessary for first separating main circuit breaker, falling pantograph, from hardware-in-the-loop, ensure that locomotive will not be in rising bow state
Under carry out the disconnection conversion of high voltage isolator, it is to avoid the electrical network tripping operation caused due to high voltage isolator misoperation or suspension
Catastrophe failure；This circuit ensure that locomotive under rising bow state, once the separating brake electric pneumatic valve of corresponding high voltage isolator due to
Altering electricity or interference etc. when being obtained electric by false triggering, locomotive also can first separate main circuit breaker, fall pantograph, then carries out high_voltage isolation and open
Close and disconnect conversion, it is to avoid the conversion of high voltage isolator bringing onto load causes electric arc and damages equipment on car.
