Having breaker to occupy, volume is big, and heavier mass, volume is big, big by external environment influence, problem inconvenient for use；Improve production simultaneously
The safety of product.
To solve the above-mentioned problems, the technical scheme is that：Electric locomotive high-voltage circuitbreaker, including circuit breakers pole
Column, operating mechanism, cable shoes, circuit breaker polar are mounted on behind mounting plate, and operating mechanism is fixed on before mounting plate, feature
It is：It is ground connections socket to have set pipe insert seat, upper back at the rear portion of breaker, is arrester socket on the right of rear portion.It is disconnected
The right is PT connection sockets in the middle part of the device of road, and the middle part left side is busbar connection plug；Vacuum interrupter is sealed in circuit breaker polar,
Vacuum interrupter static side is connect with ground connections socket, arrester socket and set pipe insert seat, movable end of vacuum arc extinguishing chamber and busbar
Connection plug connects socket connection with PT, and movable end of vacuum arc extinguishing chamber is connect by insulated tension pole with operating mechanism, vacuum interrupter
There is pressure sensor on the metal-back of moved end；The set pipe insert seat of cable shoes and casing connection, casing and circuit breaker polar connects.
Spring operating mechanism may be used in operating mechanism, can also use permanent magnet mechanism, can also use compressed air for
The pneumatic operating mechanism of power.
Electric locomotive high-voltage circuitbreaker is using vacuum interrupter as cut-offfing and breakover element, vacuum extinction outdoor are adopted
With insulating materials by pressure injection mode, or by by insulator injection moulding being first after insulating element again by vacuum extinction
Chamber pressure enters the mode at reserved mounting hole and effectively cut-offs unit to be formed.Pressure sensor is for monitoring vacuum extinction
The vacuum degree of room changes, and when vacuum degree deficiency, the pressure on the metal shell of moved end reduces.Pass through vacuum extinction chamber internal pressure
Monitoring, predict the state of breaker, reduce the generation of operation troubles, improve the safety of operation.
Each plug is designed as pyramidal structure with socket insulating contact surface, is realized and is connected by spring touch finger between conduct piece.Bullet
Spring fingertip also provides 1-2 millimeters of activity space for abutting joint.Watchband type structure may be used in spring touch finger, can also use
Cyclic structure.
Breaker surface is coated with and partly leads bonding layer, and surface induction charge is grounded, while reducing to environment
Electromagnetic radiation.
In above-mentioned technical proposal, being applied in combination for a variety of components may be implemented, effectively reduce floor space, have compared with
High integrated level can preferably solve the roof area of electric locomotive shared by breaker.
As a result of above-mentioned design, compared with the prior art, the invention has the advantages that：Volume of switch is reduced, is collected
It is high at degree, it is safe.

Below in conjunction with attached drawing embodiment, present invention is further described in detail.
Embodiment 1
As shown in Figure 1 and Figure 2, electric locomotive high-voltage circuitbreaker, including circuit breaker polar 4, operating mechanism 7, cable shoes 1,
Circuit breaker polar 4 is mounted on behind mounting plate 6, and operating mechanism 7 is fixed on 6 front of mounting plate, it is characterised in that：In breaker
It is ground connections socket 3 that, which there are set pipe insert seat 14, upper back in rear portion, is arrester socket 2, breaker middle part the right on the right of rear portion
It is PT connections socket 5, the middle part left side is busbar connection plug 11.As shown in figure 3, being sealed with vacuum extinction in circuit breaker polar 4
Room 10, vacuum interrupter static side are connect with the copper piece of ground connections socket 3, arrester socket 2 and set pipe insert seat 14, and vacuum is gone out
Arc chamber moved end connect 13 connections that are flexible coupling of socket 5 with busbar connection plug 11 and PT, and movable end of vacuum arc extinguishing chamber is drawn by insulating
The driving axis connection of bar 12 and operating mechanism 7 also has pressure sensor 10.1 on movable end of vacuum arc extinguishing chamber metal-back；Cable shoes 1
