It is connected with high voltage bus, the output end of the first subordinate inverter is connected with the first end of the first breaker, the second subordinate inverter
Output end be connected with the first end of the second breaker, the second end of the second breaker and the second end of the first breaker, the 3rd
Second end of breaker and the second end connection of the 4th breaker, first end and the 3rd subordinate inverter of the 3rd breaker
Output end is connected, and the first end of the 4th breaker is connected with the output end of the 4th subordinate inverter.
As shown in figure 1, the TC cars on the left side, MP cars and M form the first module of train, the TC cars in the unit are equipped with first
Subordinate inverter, MP cars match somebody with somebody the second subordinate inverter, while configure the first breaker KM1 in the TC cars of the unit, match somebody with somebody in MP cars
Put the second breaker KM2；The TC cars on the right, MP cars and M form the second unit of train, and it is auxiliary that the TC cars in the unit are equipped with the 4th
Inverter is helped, MP cars match somebody with somebody the 3rd subordinate inverter, while configure the 4th breaker KM4 in the TC cars of the unit, are configured in MP cars
3rd breaker KM3.
Under normal circumstances, 4 subordinate inverters in railcar auxiliary power supply system are female to middle pressure bussed supply, middle pressure
Middle pressure load supplying of the line through permutation car to permutation car, KM1, KM2, KM3 and KM4 are in closure state.When 4 auxiliary are inverse
(subordinate inverter breaks down including subordinate inverter faults itself and connect when the subordinate inverter become in device breaks down
Earth fault), it is only necessary to the breaker that the output end for the subordinate inverter for making to break down with this is connected disconnects, you can event will occur
The subordinate inverter excision of barrier, namely the connection line of the subordinate inverter to break down and middle pressure bus has been cut off, make generation
The subordinate inverter of failure can not be to middle pressure bussed supply, and the subordinate inverter of other three normal works can undertake entirely
The operation of car load.Because subordinate inverter uses Redundancy Design, i.e., the power of every subordinate inverter is 200 kilovolt-amperes, four
The general power of platform subordinate inverter is 800 kilovolt-amperes, and it is 600 that the middle pressure on permutation car, which loads power required when all working,
Kilovolt-ampere, so even if after break down subordinate inverter is cut off, remaining three subordinate inverters still can be with
Meet the operation demand of the middle pressure load on train, without cutting off the load of half compressor of air conditioner, therefore can ensure in compartment
The comfort level of passenger.
For example, if the first subordinate inverter in first unit breaks down, it is only necessary to disconnect the first open circuit
Device can cut off the first subordinate inverter, and the subordinate inverter of other three normal works can undertake the fortune of full car load
OK, without cutting off the load of half compressor of air conditioner, therefore the comfort level of passenger in compartment can be ensured.
Because the middle all middle pressure loads pressed on bus have independent breaker protection, when pressure load event in any one
During barrier, breaker then disconnects the middle pressure load broken down and the connection of middle pressure bus, to ensure that middle pressure bus is unaffected.
The present embodiment provide railcar auxiliary power supply system, by the first subordinate inverter, the second subordinate inverter,
The input of 3rd subordinate inverter and the 4th subordinate inverter is connected with high voltage bus, the output end of the first subordinate inverter with
The first end connection of first breaker, the output end of the second subordinate inverter are connected with the first end of the second breaker, and second is disconnected
Second end at the second end of road device and the second end of the first breaker, the second end of the 3rd breaker and the 4th breaker connects
Connect, the first end of the 3rd breaker is connected with the output end of the 3rd subordinate inverter, the first end of the 4th breaker and the 4th auxiliary
Help the output end of inverter to connect, when a certain subordinate inverter ON TRAINS breaks down, not off-load operation can be realized,
Ensure the comfort level of passenger in compartment.
It should be noted that in the prior art, if two subordinate inverters being in different units on train
Break down, then need to make four wholly off work of subordinate inverter, can not more ensure comfortable temperature in compartment, and this hair
If two subordinate inverters being in different units on train break down in bright, also only need what excision was broken down
Subordinate inverter, remaining two subordinate inverters still can be with normal work.
Further, the first breaker is first contactor, and the second breaker is second contactor, and the 3rd breaker is the
Three contactors, the 4th breaker are the 4th contactor.
Further, the first breaker is the first relay, and the second breaker is the second relay, and the 3rd breaker is the
Three relays, the 4th breaker are the 4th relay.
Further, as shown in Fig. 2 another railcar auxiliary power supply system that Fig. 2 is provided by the embodiment of the present invention
The structural representation of system.Also include：
First isolating device, the second end of the second breaker are connected by the second end of the first isolating device and the first breaker
Connect.
Second isolating device, the second end of the second breaker are connected by the second end of the second isolating device and the 3rd breaker
Connect.
3rd isolating device, the second end of the second breaker pass through the second isolating device and the first end of the 3rd isolating device
Connection, the second end of the 3rd isolating device is connected with the second end of the 4th breaker.
As shown in Fig. 2 TC cars in first module are equipped with the first isolating device, the M cars in second unit be equipped with second every
From device, the TC cars in second unit are equipped with the 3rd isolating device, permutation car totally three isolating devices.
Under normal circumstances, 4 subordinate inverters in railcar auxiliary power supply system are female to middle pressure bussed supply, middle pressure
Middle pressure load supplying of the line through permutation car to permutation car, KM1, KM2, KM3 and KM4 are in closure state.In fruit part
Press busbar grounding, it is only necessary in the part of ground connection bus can will be pressed to isolate by the isolating device installed ON TRAINS, will
Isolating device at left and right sides of earth point disconnects, and without whole piece bus is all isolated, now train only needs to reduce
25% middle pressure load.
