Description
Technical field
The utility model relates to a kind of breaker apparatus, particularly relates to the special-purpose single-phase bipolar circuit breaker cart of a kind of railway.
Background technology
In power control switch equipment and electric power system acceptance and electrical power distribution, use circuit breaker usually, existing circuit breaker cart comprises vehicle frame, be arranged on the mechanism case on the vehicle frame, be arranged on the vehicle frame breaker body that is connected with mechanism case and forms by insulator, outlet seat, contact, vacuum interrupter and insulated tension pole and be arranged on propulsive mechanism and rolling mechanism on the vehicle frame.One group of breaker body only is set on the vehicle frame, can not adapts to the power supply control requirement of Heavy-Haul Railway, express locomotive; Wherein, contact is the flat contact of duck-beak type, easily misplaces during contact, causes loose contact, and heating is serious, and it is inhomogeneous to dispel the heat; Propulsion plant adopts the reaping hook structure, advances dumb; Rolling mechanism only is installed in wheel on the vehicle frame, no guiding mechanism, and it is inaccurate that handcart is located in cabinet, skew about easily taking place.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of simple to operate, advances laborsavingly, and through-current capability is big.Short circuit interruption value height, reliability height, the special-purpose single-phase bipolar circuit breaker cart of the railway that floor space is little.
The special-purpose single-phase bipolar circuit breaker cart of the utility model railway comprises vehicle frame, be arranged on the mechanism case on the vehicle frame, be arranged on two groups of breaker bodies that are connected with mechanism case on the vehicle frame and be arranged on the propulsive mechanism on the vehicle frame, interlock detent mechanism, rolling mechanism and earthing device.Wherein, breaker body comprises that an end is fixed on the vehicle frame, two insulators that the other end is connected with last outlet seat and following outlet seat respectively, the insulation strut that the outlet seat was connected and fixed under its two ends reached with last outlet seat respectively, be positioned at the vacuum interrupter between upper and lower outlet seat, with the contact that upper and lower outlet seat leading-out terminal is connected, its two ends respectively with mechanism case in connecting lever and the connecting lever of vacuum interrupter lower end be rotationally connected have an insulated tension pole that compresses spring.Contact is the cluster rounded contact, by moving bar, is arranged on the moving bar and by grid and separates and be made up of the fixing contact of binding spring; Propulsive mechanism is the worm and gear propulsive mechanism, comprise the mounting panel that is fixed on the vehicle frame, be installed in the worm and gear on the mounting panel, the rocking handle that is connected with worm screw, the cardan shaft that is connected with worm gear, cardan shaft two ends and vehicle frame are rotatably assorted, its end be provided with switch cubicle in both sides trough roller propelling connecting lever movingly; The interlocking detent mechanism is connected with mechanism case, can slide up and down, and is used for the location of handcart in switch cubicle and the reciprocal interlocking of progradation and switch cubicle; Rolling mechanism is made up of wheel and directive wheel.Roll on the guided way of directive wheel in switch cubicle, be used for handcart and in switch cubicle, move.Wheel is used for handcart and moves outside switch cubicle;
The operation principle of the special-purpose single-phase bipolar circuit breaker cart of the utility model railway is, when being in gate-dividing state, shake rocking handle, drive cardan shaft by worm and gear and rotate, advance connecting lever to slide along the groove of switch cubicle both sides, directive wheel rotates thereupon, when handcart pushed in the switch cubicle to run location, the interlocking detent mechanism inserted the location hole in the switch cubicle, and handcart is locked, at this moment, by mechanism case breaker body is implemented to close a floodgate; When needs were released handcart, mechanism case made breaker open operation, and interlocking device unlocks simultaneously, and handcart just can be released from switch cubicle.
The special-purpose single-phase bipolar circuit breaker cart of the utility model railway advantage is simple to operate, advances laborsavingly, and through-current capability reaches 3150A, and the short circuit interruption value reaches 40kA, the reliability height, and floor space is little.Be mainly used at a high speed, heavy railway electrical locomotive power control switch equipment, also can be used for the usefulness that electric energy was accepted and distributed to electric railway traction electric substation, switching station, subregion booth etc. as the railway dragging electric power system.
