Background technology
PASS equipment (Plug And Switch System, plug-in type device for switching) is a kind of novel outdoor gas insulated metal enclosed swit chgear between conventional air insulation switchgear (AIS) and gas-insulated switchgear (GIS).It is based on the GIS technology, all necessary function of switch gap such as circuit breaker, isolating switch, earthed switch, current transformer etc. all are integrated in closed metal (cast aluminium) case of the same SF6 of being full of gas as a module, and, realize single female wiring or two female wiring according to the wiring requirement of electric substation.Be connected with the turnover line with substation busbars by insulating sleeve, every is independent rack mutually.3 phase PASS modular assemblies promptly are equivalent to a complete high-tension cell, and other charging equipment all seals assembling except that bus.PASS adopts the design of isolating/grounding switch three stations, a shared electric operating mechanism.Because be by non-maintaining switch designs, reliability at GIS improves day by day, on the basis that maintenance significantly reduces, it structurally has compactness, miniaturization, few stube cable and takes up an area of few characteristics, has reliability height, intelligent degree height, characteristics that maintenance is few on performance.The PASS switch that uses in the electrical network is mainly assembled by imported equipments and parts at present, and wherein the transmission of one of most important parts three-station also is to rely on import, complex structure, cost height.
Summary of the invention
In order to overcome above-mentioned defective, it is a kind of simple in structure that the utility model provides, and cost is low, little, the stable performance of driving error, the three three good station isolation earthing switch transmission devices of synchronism that link.
The technical solution adopted in the utility model is: a kind of three station isolation earthing switch transmission devices, comprise transmission case, body output shaft, driving gear, driven gear, mechanism's output shaft, connecting lever, mate gear and organization gear, described transmission case is positioned at the rear side of mechanism and is connected with the three-station body, body output shaft and mechanism's output shaft all are arranged in the transmission case, and wherein mechanism's output shaft runs through transmission case and links to each other with mechanism.In transmission case, mechanism's output shaft is provided with driving gear, the body output shaft is provided with driven gear, driving gear is meshed with driven gear, and on mechanism's output shaft, a side of driving gear is provided with connecting lever, connecting lever is arranged in the transmission case, transmission case is stretched out in its upper end, connecting lever is connected by joint with connecting rod, and on mechanism's output shaft, the arranged outside that is positioned at transmission case has mate gear, mate gear is meshed with organization gear.
The utility model adopts gear drive to combine with the transmission of connecting lever connecting rod, is applied in PASS three-station body and inter-agency, makes and carries out effective transmission between body and the mechanism, to reach accurate deciliter function of isolation, ground connection; Structure of the present utility model can realize the mutual conversion of in-house rotating shaft and isolation knife movement angle, also can effectively regulate, promptly not only can regulate the position of isolation knife by connecting rod, also can regulate by the no-load voltage ratio that changes gear, increase the approach of regulating, improved transmission efficiency, reduced driving error, break the drawback that relies on external import, reduced cost.
