Abstract
The utility model relates to a GIS voltage transformer control device, comprising a hand wheel, an insulating rod, an eccentric gear, a driven member, an isolation device, and a connecting piece. In a housing of a GIS voltage transformer, the insulating rod is fixedly installed through a fixing base. The isolation device is disposed in a cavity of the GIS voltage transformer housing thorugh the insulating rod. The isolation device is provided with the eccentric gear. The eccentric gear is connected with the insulating rod. The eccentric gear is connected with the driven member through the connecting piece, and drives a conducting rod to move up and down under the action of the driven member. Since the isolation device is an arc housing in a U-shaped structure, high-pressure sulfur hexafluoride top-blowing gas generated in operation is collected in the arc housing in the U-shaped structure. The gas forms blowback through gradually narrow side plates, and momentary contact arc is eliminated, so that operation is safer and more reliable. Since the isolation device is designed in an arc structural style, so that internal electric field distributes uniformly.
Description
Technical field
The utility model relates to power industry and is used for the voltage transformer conducting rod is disconnected device with closure, specifically a kind of GIS voltage transformer operating device.
Background technology
Relevant patent documentation does not retrieve the GIS voltage transformer operating device identical with the utility model structure at present as yet by retrieval.Existing GIS voltage transformer mainly realizes that by bar linkage structure the disconnection of conducting rod is with closed, the parts that this class formation relates to are more, the installation and maintenance difficulty, and in use occur easily former thereby make conducting rod be difficult in time disconnect or closed phenomenon because of mechanism structure, and in the process that maintenance is installed, waste time and energy, increased cost.In order to adapt to the needs that current electric equipment develops to miniaturization, lightness direction, thus be necessary the operating device of existing GIS voltage transformer is improved, to satisfy actual needs.
Summary of the invention
The purpose of this utility model is that a kind of improvement on existing GIS voltage transformer basis will be provided, and has a kind of GIS voltage transformer operating device simple in structure, easy to install.
Technical characterictic of the present utility model is: considering that compact conformation, basis easy to use are designed to a kind of GIS voltage transformer operating device of being made up of handwheel, insulating bar, eccentric wheel, driven member, spacer assembly, connector, are fixed with insulating bar by holder in the housing of GIS voltage transformer; Spacer assembly is arranged in the cavity of GIS voltage transformer housing by insulating bar; Be provided with eccentric wheel in spacer assembly, described eccentric wheel links to each other with insulating bar; Eccentric wheel is connected with driven member by connector, and the drive conducting rod moves up and down under the effect of driven member; Handwheel is arranged on the outside of GIS voltage transformer housing, and links to each other with insulating bar; Described spacer assembly is the arc shell of " U " shape structure.
Described handwheel is a disk body that high-strength insulating material is cast.
Described insulating bar is an insulation body of rod that adopts epoxy resin composition to make.
Described eccentric diameter and eccentric throw are that the stroke according to driven member designs.
Described spacer assembly is that the arc shell of " U " shape structure is to say that integral body is made of last capping, side plate, base plate, and last capping is that circular arc is connected with side plate; Described side plate is the arc plate body of " U " shape; Side plate is that circular arc is connected with base plate.
During use, rotate handwheel, insulating bar drives eccentric wheel and rotates under the rotation of handwheel, and connector drives the driven member motion under eccentric rotation, and drives conducting rod and move up and down, thereby carries out the disconnection and closure of voltage transformer.
The utility model has the advantages that: owing to be provided with insulating part, thus high electric field and the external world in the instrument transformer separated, make handling safety reliable; Realize moving up and down owing to adopt eccentric wheel to be combined with driven member, thereby make operating device simple in structure; Because spacer assembly is the arc shell of " U " shape structure, thereby the high pressure sulfur hexafluoride top-blown gas that will produce in the time of will operating is collected in the arc shell of " U " shape structure, and by the side plate that progressively dwindles gas is formed blowback, eliminated the moment contact arc, avoided the damage of components and parts, made the operation safety and reliability; Because spacer assembly is designed to the version of arc shape, thereby internal electric field is evenly distributed; Since rational in infrastructure, easy to use, so very big practical and popularizing value is arranged.
