In order to which technical solutions in the embodiments of the present application is more clearly and completely described, below in conjunction with this Shen
Attached drawing that please be in embodiment, technical solutions in the embodiments of the present application are introduced.Obviously, described embodiment is only
Some embodiments of the present application, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art
The every other embodiment obtained without making creative work, shall fall in the protection scope of this application.
Referring to Fig. 1, Fig. 1 is the structure of the high pressure circuit on side of overhead contact line of power car in a kind of EMU provided herein
Figure；Including it is a plurality of it is in parallel by electric branch 1, that the side for being electrically connected with other power cars in EMU connects branch 2, pattern is defeated
Enter detection circuit 3 and controller 4；
Wherein, included main circuit breaker and the first end mounted on main circuit breaker and high-voltage fence contact line by electric branch 1
Between pantograph；The second end of each main circuit breaker homogeneously connects, as the output end by electric branch 1 of each item parallel connection,
Primary side winding for the tractive transformer with power car is connect；
It includes the high voltage isolator that first end is connected with by the output end of electric branch 1, high voltage isolator that side, which connects branch 2,
Second end as other contact, for being connect with the other contact of other power cars in EMU；
Pattern input detecting circuit 3 is for detecting mode selection command input by user；
Controller 4 is connected with pattern input detecting circuit 3, and respectively with main circuit breaker, pantograph and high voltage isolator
It couples (as shown in phantom in Figure 1)；For being to be opened to high_voltage isolation when double power vehicle traction mode instructs in mode selection command
It closes and sends close command, be to send shutdown to high voltage isolator when single-power vehicle traction mode instructs to refer in mode selection command
It enables；And it controls and is arbitrarily connected by electric branch 1 to export power supply.
Specifically, for EMU, the effect of the high pressure circuit on side of overhead contact line of power car is to obtain from high-voltage electricity net side
Electric energy powers to the primary side of tractive transformer, to export electric energy from the secondary side of tractive transformer, powers for EMU.Often
Rule, the device in high pressure circuit on side of overhead contact line generally comprises pantograph, main circuit breaker and earthing or grounding means.When pantograph rising bow and master is disconnected
When road device is closed, high pressure net side is channel status, and electric energy can backward be exported by tractive transformer；When bow or master drop in pantograph
When breaker disconnects, high pressure net side is then off state.Also, in order to realize that arc extinguishing, main circuit breaker are usually required in pantograph
It is just closed after rising bow, and is first disconnected before pantograph drop bow.
In order to carry out redundancy protecting to high pressure circuit on side of overhead contact line, high pressure circuit on side of overhead contact line provided herein is specifically provided with simultaneously
Connection it is a plurality of by pantograph and main circuit breaker constitute by electric branch 1 (in Fig. 1 only symbolically show two).Due to every by
Electric branch be all be connected in parallel between High-Voltage Network side contacts line and tractive transformer primary side winding input terminal, if therefore wherein one
It is connected by electric branch 1, the electric energy of high pressure net side can pass through tractive transformer output.By the setting of redundancy protecting,
After wherein one pantograph or main circuit breaker in by electric branch 1 breaks down, controller can enable other normal
By electric branch 1 be connected, the normal operation of Train electrical system is maintained with this.
For each by electric branch 1, pantograph is mounted on the first end of high-voltage fence contact line and main circuit breaker, when its liter
When bow, high-voltage fence contact line is just connected with the first end of main circuit breaker.The second end of every main circuit breaker in by electric branch 1
Mutual short circuit connects as each item by the output end of electric branch 1 so as to the input terminal of the tractive transformer primary side winding with power car
It connects and exports electric energy.
Certainly, routinely, in order to be monitored, calculate to circuit state and control, those skilled in the art generally may be used also
The devices such as some detections or protection to be arranged in circuit.For example, high voltage potential transformer is arranged in by electric branch 1, so as to
Monitor the input voltage of high pressure net side；It is being set between by the output end of electric branch 1 and the input terminal of tractive transformer primary side winding
High-tension current inductor is set, to monitor the input current of high pressure net side；The output end of tractive transformer primary side winding with connect
Earth current mutual inductor is set between ground device, to monitor the earth current of high pressure net side；By electric branch 1 output end with
Arrester is set between ground terminal, to protect circuit components.These contents can be by those skilled in the art according to conventional skill
Art means are voluntarily arranged, and the application is not limited thereto.

The side that tractive transformer is electrically connected connects branch 2.Specifically, connect by this branch 2 mainly include high voltage isolator, high pressure every
The first end for leaving pass is connect with this power car by 1 output end of electric branch, and the other end is then as the other contact of this power car,
It is connect for the other contact with other power cars.
As a result, when the other contact of two power cars is connected with each other and the high voltage isolator of two power cars is in conducting
When state, the tractive transformer primary side winding of two power cars is just connected in parallel, meanwhile, each item of two power cars is propped up by electricity
Road 1 is also parallel with one another, then, can be simultaneously two by electric branch 1 by any normally in two power cars and moved
Power vehicle is powered, that is, realizes double power vehicle traction mode.And when only needing single-power vehicle traction mode, can by high pressure every
Shutdown is left to open and cancel the connecting line between the other contact of two power cars.It as a result, should by provided herein
High pressure circuit on side of overhead contact line can easily realize the circuit structure switching under two kinds of grouping formulations.
And in order to realize the switching under two kinds of grouping formulations, high pressure circuit on side of overhead contact line provided herein according to user intention
Further include pattern input detecting circuit 3, for receiving mode selection command input by user.When user selects the traction of single-power vehicle
When mode instruction, controller 4 just controls high voltage isolator shutdown, then controls any one and is connected so as to defeated by electric branch 1
Go out power supply；And when user is in the connection completed by two power cars between contact and when having input the instruction of double power vehicle traction mode, control
Device 4 processed just controls high voltage isolator conducting, then controls any one and is connected by electric branch 1 to export power supply.As for tool
Which kind of pattern input detecting circuit 3 body uses, and those skilled in the art can voluntarily select to be arranged, for example, key press detecting circuit or
Switch detection circuit etc., the application is not limited thereto.
As it can be seen that in EMU provided herein power car high pressure circuit on side of overhead contact line, passing through be arranged it is multigroup in parallel
It, can also be by controlling the other break-make of branch 2 that connects come flexibly suitable while by electric branch 1 effectively to realize to circuit redundancy protecting
For single-power vehicle traction mode and double power vehicle traction mode, therefore the application can effectively improve the flexible of circuit and be applicable in simultaneously
