Abstract

The utility model relates to a driving device of a 252kV GIS (Gas Insulated Sub-Station) breaker, comprising an operating mechanism, a connecting rod assembly, a mechanism chamber, a bracket, an outer turn arm, an inner turn arm, a mechanism case assembly, a heavy plug connector, a heater and a ventilation device. The driving device is characterized in that the operating mechanism is connected by the bracket and is arranged above the mechanism chamber, an output turn arm of the operating mechanism is connected with the outer turn arm by the connecting rod assembly, the heavy plug connector is arranged under a case body, the heater is arranged on a bottom plate of the case body, the ventilation device is arranged on a side plate of the case body, and an inner cavity of the mechanism chamber is communicated with an inner cavity of an arc extinguish chamber and is sealed with the outer turn arm by a double-channel seal ring. The utility model has the advantages of small volume and compact structure, is stable and reliable, is convenient to install and check, and the like.

Description

252kVGIS circuit breaker transmission device

Technical field

The utility model relates to high-voltage switch gear transmission facility technical field, particularly a kind of 252kVDis circuit breaker transmission device.

Background technology

Development along with the high-voltage switch gear technology, requirement to the reliability of equipment and stability is more and more higher, the urban power consumption is anxious to be increased, made 252kV even 550kVGIS power station enter the urban district or near outskirts of a town, the spatial volume that an urgent demand GIS switch power station reduces floor space as far as possible or goes into the hole down, it is big that present switchette power station exists volume, poor stability and the inconvenient shortcoming of installation maintenance.

Summary of the invention

It is little that the purpose of this utility model provides a kind of spatial volume, and compact conformation is reliable and stable, is convenient to install the 252kVGIS circuit breaker transmission device of maintenance.

The utility model is to realize like this, it comprises operating mechanism, the connecting rod assembling, support, the mechanism chamber, outer connecting lever, interior connecting lever, the mechanism case assembling, the heavy duty plug connector, heater and ventilation unit, it is characterized in that operating mechanism connects and be arranged on the top of mechanism chamber by support, the output toggle arm of operating mechanism is connected with outer connecting lever by the connecting rod assembling, the heavy duty plug connector is arranged on the casing below, heater is arranged on the box bottom, ventilation unit is arranged on the box side, the indoor chamber of mechanism communicate with the arc control device inner chamber and and outer connecting lever between seal by the double sealing circle.

It is little to the utlity model has volume, and compact conformation is reliable and stable and be convenient to install the advantage of maintenance.
