Abstract

The utility model belongs to the field of high-voltage electrical apparatuses, and discloses a three-phase electromagnetic voltage transformer with a disconnecting switch for a geographic information system (GIS). The three-phase electromagnetic voltage transformer with the disconnecting switch for the GIS mainly comprises a shell body, a high-voltage insulator, a direct-operated disconnecting switch mechanism, high-voltage windings, low-voltage windings for measurement, a low-voltage winding for protection, an iron core and an insulating medium. The direct-operated disconnecting switch mechanism comprises an electric conduction connecting mechanism and an operating mechanism, wherein the electric conduction connecting mechanism and the operating mechanism are connected through an insulating pull rod.

Description

A kind of GIS three-phase electricity magnetic-type voltage transformer of band isolating switch
Technical field
The utility model relates to a kind of three-phase electricity magnetic-type voltage transformer; relate in particular to a kind of GIS three-phase electricity magnetic-type voltage transformer of being with isolating switch; belonging to the High-Voltage Electrical Appliances field, is a kind of electromagnetic potential transformer that has voltage measurement and relaying protection function in the electric power system.
Background technology
At present in electric power system, if be connected with isolating switch between the three-phase electricity magnetic-type voltage transformer of GIS and the bus, when before power frequency withstand test, doing seasoned test isolating switch is closed, add the no-load voltage ratio that rated voltage checks electromagnetic potential transformer; When doing the power frequency withstand voltage test, disconnect isolating switch.Isolating switch is what to separate with three-phase electricity magnetic-type voltage transformer, causes waste at human and material resources, and the production cycle is long, influences test efficiency, and the small product size of producing is bigger, brings inconvenience when transportation and use.
Summary of the invention
Technical problem to be solved in the utility model is: at the problem that prior art exists, provide a kind of GIS three-phase electricity magnetic-type voltage transformer with the band isolating switch, save cost, enhance productivity.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of GIS three-phase electricity magnetic-type voltage transformer of band isolating switch; mainly by housing, high-tension insulator, directly moving isolating switch mechanism, high pressure winding, measure with the low pressure winding, protect and form with low pressure winding, iron core and dielectric; described three high pressure windings are evenly distributed on the base plate, are mutually 120 degree angles.
Described straight moving isolating switch mechanism comprises conduction bindiny mechanism and operating mechanism, and described conduction bindiny mechanism is between insulator and the high-tension coil, and described operating mechanism is in the center of base plate.
Described conduction bindiny mechanism and operating mechanism adopt insulated tension pole to connect, and described operating mechanism design has disconnection and two stations that close, and adopts the lip-type seal circle as the translation seal structure.
The beneficial effects of the utility model are: the utility model originally independently isolating switch be designed in the three-phase electricity magnetic-type voltage transformer, effectively improve the test efficiency of GIS, reduce the input of human and material resources, save cost, shorten the production cycle, and having effectively reduced the volume of GIS product, convenient transportation is saved and is used the soil.
