The various troubles that can avoid because of high voltage isolator causes are arranged to the net side cabinet of the two line vacuum circuit breaker of installation of cancellation high voltage isolator and adoption and two high voltage potential transformer schemes, improve electric locomotive line vacuum circuit breaker's redundant reliability, the reliability of increase net side cabinet simultaneously.
Description
Technical field
The present invention relates to electric locomotive control system technical field.
Background technology
AC transmission electric power locomotive domestic at present is respectively provided with high voltage isolator, as shown in figure 1, being used for motorcycle pantograph
High-voltage electrical apparatus isolation.And major part high voltage isolator mainly adopts microcomputer to control, after operator send instruction, by micro-
Machine automatically controls high voltage isolator.When crew member's maloperation, Control Program for Microcomputers [Digital Research] is disorderly and high voltage isolator controls electricity
When road goes wrong, there is misoperation phenomenon in high voltage isolator, causes 25KV contact net scaling loss when serious, threatens vehicle and people
Body safety.Meanwhile, domestic AC transmission electric power locomotive major part does not have line vacuum circuit breaker Redundancy Design, when locomotive operation
Once line vacuum circuit breaker breaks down, then locomotive can be caused to be not normally functioning or even stop transport.
Content of the invention
Technical problem solved by the invention is to provide a kind of high use for electric locomotive of reliability double line vacuum circuit breaker net
Sidecar.
The technical solution used in the present invention is the double line vacuum circuit breaker net side cabinet of one group of use for electric locomotive, including net side cabinet cabinet
Body, rear cross beam above cabinet is provided with two supports insulative, and pantograph side 25KV high-tension electricity is delivered to very by supports insulative
The high voltage input terminal of empty main circuit breaker, side wall about cabinet is installed two high voltage potential transformers altogether, respectively with two vacuum
The high voltage input terminal of main circuit breaker is in parallel, underframe in net side cabinet is provided with two line vacuum circuit breakers, a high-voltage earthing is opened
Spark gap in pass, a cabinet.
Two identical line vacuum circuit breakers rotate against 90 ° of installations, in upper end and the middle part of line vacuum circuit breaker,
Grounding contact is installed.
In cabinet, spark gap is installed in the middle of two line vacuum circuit breakers, is connected with line vacuum circuit breaker high-voltage output end.High
Pressure earthed switch is double pivoted arm structure, is operated by same handle, when rotating clockwise handle, two pivoted arms will be simultaneously to cabinet
Central rotational.
The invention has the beneficial effects as follows by using double line vacuum circuit breaker, double high voltage potential transformers, cancel high pressure every
Leave the net side cabinet design closing mounting arrangements, the various accidents causing because of high voltage isolator misoperation can be avoided, solve simultaneously
Single line vacuum circuit breaker net side cabinet of having determined causes the problem that locomotive is stopped transport because line vacuum circuit breaker breaks down, and improves electric power machine
The redundant reliability of car line vacuum circuit breaker, the reliability of increase net side cabinet.There is provided efficient, safe, efficient railway for people
Electric propulsion transporting equipment, one of net side cabinet net side high voltage component before tractive transformer as electric locomotive integrated, can
High by property, the risk having an accident is little.
Brief description
Fig. 1 is prior art construction schematic diagram.
Fig. 2 is this utility model structural representation.
In figure labelling：1- cabinet, 2- line vacuum circuit breaker 3- high voltage ground switch, 4- high voltage potential transformer, 5- supports
Insulator, 6- adapter, 7- interlocking key case, spark gap in 8- cabinet.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Fig. 2 two cabinet inner support insulators 1 are installed on rear cross beam above net side cabinet, for by pantograph side
25KV high-tension electricity delivers to line vacuum circuit breaker 2 high voltage input terminal.Two high tension voltage mutual inductances are installed altogether on side wall about net side cabinet
Device 4, in parallel with the high voltage input terminal of two line vacuum circuit breakers 2 respectively, for line vacuum circuit breaker 2 front end 25KV high input voltage
Electric network voltage detects.It is provided with underframe in net side cabinet in two line vacuum circuit breakers, 3, cabinet of 2, high voltage ground switch and keep away
Thunder device 8；Two identical line vacuum circuit breakers 2 rotate against 90 ° of installations, and now, the gas circuit of two main circuit breakers and circuit connect
Mouthful position rotates against 90 °, in upper end and the middle part of line vacuum circuit breaker 2, is provided with grounding contact, for by vacuum master
The input/output terminal ground connection of chopper；High voltage ground switch 3 is double pivoted arm structure, is operated by same handle, rotates clockwise
During handle, two pivoted arms will be simultaneously to cabinet central rotational it is ensured that be grounded two groups of vacuum circuit breakers 2 simultaneously；Spark gap 8 in cabinet
It is installed in the middle of two line vacuum circuit breakers 2, be connected with line vacuum circuit breaker high-voltage output end.
The technical solution of the utility model cancels high voltage isolator, mutual using double line vacuum circuit breakers and double high tension voltage
Sensor, it can be avoided that the various accidents that high voltage isolator misoperation causes, solves single line vacuum circuit breaker net side simultaneously
Cabinet causes the problem that locomotive is stopped transport because line vacuum circuit breaker breaks down.Improve the reliability in the design of net side cabinet, reduce and send out
Make trouble thus risk, for people provide efficient, safe, efficient railway electric traction transporting equipment ensure.
