Description
Technical field
The present invention relates to railway vehicle device test field, more particularly to a kind of test of track traffic automatic neutral-section passing device
System and test method.
Background technology
Track traffic automatic neutral-section passing device is the key equipment of electric railway, the control on equipment locomotive/EMUs
Control equipment, locomotive/motor-car power-off is automatically controlled when by non-Electric region, electricity is closed, to avoid locomotive/motor-car powered by non-Electric region
And cause electrical equipment to damage.
The pattern of the existing track traffic automatic passing over of neutral section of China：Ground magnetic strength device is buried on track near non-Electric region,
Track traffic automatic neutral-section passing device and induction coil are equipped on locomotive/motor-car, can be felt by induction coil during the magnetic strength device of ground
Electric impulse signal should be gone out, device is received and produce after electric pulse response wave shape, control locomotive/motor-car power-off, conjunction electricity.Such as Fig. 1 institutes
Show, when train travel direction is for forward.During the close non-Electric region of locomotive/motor-car, first T2 induction coils skim over advance notice ground magnetic strength
Device, induces electric impulse signal, and device produces an advance notice response wave shape after receiving, after locomotive/motor-car control system is received, first
Current of electric unloading order is sent, after current of electric is reduced to 0, then disjunction main circuit breaker order is sent out, cuts off what contact net was brought
25kV high-tension electricities.Then T1 induction coils are skimmed over and force ground magnetic strength device, induce electric impulse signal, and device produces one after receiving
It is individual to force disconnected response wave shape, direct disjunction main circuit breaker after locomotive/motor-car control system reception.When anticipating signal fails, by force
Compel disconnected response wave shape just to play a role.Behind non-Electric region, T2 induction coils skim over recovery ground magnetic strength device, induce electric arteries and veins
Signal is rushed, device produces a recovery response wave shape after receiving, after locomotive/motor-car control system is received, send out closure main circuit breaker
Order, then dynamo current loading instruction, current of electric will then revert to previous level.Then T1 induction coils skim over recovery ground
Magnetic strength device（It is standby）, electric impulse signal is induced, device produces a recovery response wave shape, recovers as locomotive/motor-car after receiving

The 10V dc sources of individual belt switch, manually close switch-dividing and produce a pulse signal.Two is to skim over ground using magnet
Magnetic strength device is tested：Hand magnet skims over ground magnetic strength device, produces a magnetic strength induction signal and carrys out detection means response wave shape data.
But two methods can not detect advance notice, force disconnected, recovery response wave shape three's temporal and logic relation；Can not simulate
Actual magnetic strength induction signal, actual magnetic strength induction signal be a set of pulses row, its amplitude, pulse width, cycle with velocity correlation；
Can not intactly detection means response wave shape data, both test methods differ farther out with actual, and result of the test can not be just
Really the quality of judgment means is fine or not.

S.A.5. the normal then judgment means open fault detection of step S.A.2 and step S.A.4 is normal.
The 13. track traffic automatic neutral-section passing device test methods according to any one of claim 7 to 11, its feature exists
In：Also detect including device short trouble, concrete steps include：
S.B.1. the T1 is switched into one in switch, T2 switching switches, T3 switching switches, T4 switching switches to beat in centre
Position, and by two contact short circuits of bit positions, remaining is beaten in the 3rd position；
S.B.2. turn-on power switch is electricity on the track traffic automatic neutral-section passing device, detects that the track traffic is automatic
Whether the short trouble lamp of passing phase insulator device is lighted, and it be then normal to light；
S.B.3. the open circuit between the centre position Liang Ge contacts of the switching switch in centre position is played in recovering step S.B.1, and
Beat to the 3rd position；
S.B.4. again turn-on power switch is re-powered for the track traffic automatic neutral-section passing device, detects the track
Whether the short trouble lamp of traffic automatic neutral-section passing device extinguishes, and extinguishing is then normal；
S.B.5. the normal then judgment means short trouble detection of step S.B.2 and step S.B.4 is normal.
