Abstract
The utility model relates to an outdoor high voltage vacuum breaker which is of three-phase open discrete type. Each phase of the breaker is fixed over a box and formed by an upper insulation cylinder and a lower insulation cylinder, and an upper patch board is arranged over each phase. An vacuum interrupter, a conductive clip, a flexible connection, a flange and an insulation pull rod are arranged inside the upper insulation cylinder, and a current transformer and a lower patch board are arranged between the upper insulation cylinder and the lower insulation cylinder; a bracket, a permanent magnet mechanism and a driving pull rod are arranged inside the box, and the driving pull rod is connected with the insulation pull rod through the bracket and a short connection board and connected with the permanent magnet mechanism through a long connection board. The insulation part of breaker is made from poured outdoor epoxy resin, and the vacuum interrupter adopts the structure of umbrella-skirt large creep distance. No filler is needed between the upper insulation cylinder and the vacuum interrupter, and the operation part of the breaker adopts a permanent magnet mechanism. The breaker has the advantages of large output power, good output force performance, simple structure, convenient operation, reliability and free maintenance.
Description
The utility model relates to the high pressure or the high-current switch technical field of band arc extinguishing or flash guard, especially relates to a kind of vacuum circuit-breaking switch.
At present; China has the outdoor high-voltage vacuum breaker of making to divide, close the protection grid equipment of load current, overload current and short circuit current in power distribution network; but in the prior art; deciliter operating mechanism of circuit breaker all adopts spring link mechanism; the making precision prescribed height of this spring operating mechanism; complex structure, and spring easily generation fatigue in long-term operation make the reliable in action reduction of circuit breaker.
The purpose of this utility model is for overcoming the deficiency of prior art, provides a kind of operating mechanism of novelty to substitute the outdoor high-voltage vacuum breaker of spring operating mechanism.
The purpose of this utility model is achieved in that a kind of outdoor high-voltage vacuum breaker, be that three-phase opens wide discrete, the insulating cylinder of every case is made by epoxy resin, be individually fixed on the casing, be fixed with terminal block up and down on the insulating cylinder, current transformer, be provided with vacuum interrupter in the insulating cylinder, the vacuum interrupter below is connected with insulated tension pole, the insulated tension pole of three-phase links to each other with the drive stay of linkage in the casing respectively by support, be installed in the permanent magnet mechanism in the casing, its output shaft is connected with the long connecting plate of linkage, in the casing auxiliary switch is installed also simultaneously, it links to each other with the drive stay of linkage, drive stay one end also be installed on casing in proximity transducer be connected, the manual brake separating handle is housed on the casing lateral surface.
The operation principle of this circuit breaker is such: after permanent magnet mechanism obtains reclosing command, the long connecting plate of drivening rod mechanism moves to the proximity transducer direction, long connecting plate drives drive stay, thereby driving insulated tension pole moves upward, the moving bar that promotes vacuum interrupter makes its combined floodgate, and line conduction, otherwise then be the separating brake process, can carry out urgent manual brake separating with the manual brake separating handle.
The utility model is owing to adopted the permanent magnet mechanism operation of technique scheme, its output work is big, and rated short circuit drop-out current can reach 25kA, simultaneously, parts are greatly reduced, it is simple in structure, in light weight, operation is reliable, can be non-maintaining, and insulating cylinder body adopts epoxy resin to make, adopt umbrella skirt construction, creepage distance is increased, and stain resistance is strong, uses applicable to the filthy district of IV level and in height above sea level 2000～3000m area.
