Abstract
The utility model relates to the technical field of switchgears in electric power systems, in particular to a three-station isolating switch. The isolating switch is provided with an epoxy resin housing with a cavity, wherein an upper outlet seat is mounted at the front end of the cavity of the epoxy resin housing; a lower outlet seat is mounted at the bottom of the cavity of the epoxy resin housing; a movable contact, an intermediate fixed contact and an insulating screw rod are arranged in the epoxy resin housing; the intermediate fixed contact is connected with the lower outlet seat; the insulating screw rod drives the movable contact to move; one end of the movable contact is connected with the upper outlet seat; a seal plate is further arranged on the epoxy resin housing; the cavity capable of being charged with clean and dry air serving as an insulating medium is formed in the epoxy resin housing; and a grounding layer for touching is sprayed on the epoxy resin housing, so as to prevent safety accidents caused by accidental touching. The three-station isolating switch has improved insulation reliability and security reliability, and is environmental-friendly.
Description
Technical field
The utility model relates to the technical field of electric power system switchgear, especially a kind of tri-station isolating switch.
Background technology
A kind of tri-station isolating switch in the market is to use high pressure SF6 gas as dielectric with ambient air or in airtight metal cabinet, its dielectric strength is subjected to the pressure influence of the quality of ambient air and SF6 gas bigger, under the situation that if the humidity of ambient air and filth are big and the SF6 gas pressure is less, might electricly puncture, cause power grid accident and cause great economic loss, SF6 gas is the main cause that increases air themperature simultaneously, so SF6 gas is forbidden by the whole world as insulating gas.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of reliability height, a kind of tri-station isolating switch that fail safe is good are provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of tri-station isolating switch, has the epoxy package that has cavity, the front end of the cavity of epoxy package is equipped with the outlet seat, its bottom is equipped with down the outlet seat, in epoxy package, be provided with moving contact, middle fixed contact and insulation screw mandrel, middle fixed contact is connected with following outlet seat, the insulation screw mandrel drives the moving contact motion, one end of moving contact is connected with last outlet seat, also be provided with sealing plate on its described epoxy package, in epoxy package, form the cavity to be filled with as the air of the clean dried of dielectric.
On the described sealing plate grounding contact is installed, epoxy package is coated with the ground plane of touch.
The beneficial effects of the utility model are: insulating reliability of the present utility model, security reliability all are improved, and do not use environmentally harmful gas, the protection environment.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. epoxy package, 2. go up the outlet seat, 3. descend the outlet seat, 4. moving contact, 5. in the middle of fixed contact, 6. insulation screw mandrel, 7. sealing plate, 8. cavity, 9. grounding contact.
Embodiment.
In conjunction with the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of tri-station isolating switch as shown in Figure 1, has the epoxy package 1 that has cavity, the front end of the cavity of epoxy package 1 is equipped with outlet seat 2, its bottom is equipped with down outlet seat 3, in epoxy package 1, be provided with moving contact 4, middle fixed contact 5 and insulation screw mandrel 6, middle fixed contact 5 is connected with following outlet seat 3, insulation screw mandrel 6 drives moving contact 4 motions, one end of moving contact 4 is connected with last outlet seat 3, also be provided with sealing plate 7 on the epoxy package 1, formation can be filled with the cavity 8 as the air of the clean dried of dielectric in epoxy package 1, grounding contact 9 is installed on the sealing plate 7, and epoxy package is coated with the ground plane of touch.
The utility model is sealed in electric conductor in the loop in the epoxy package 1,, keeps apart with external environment condition as dielectric with the air of clean dried; The joint of last outlet seat 2, following outlet seat 3 adopts the design of compound inslation and radome, is connected with other vigour parts; Electric conductor reaches connection, isolation and the earthing position in loop in straight-line mode; The outer surface reliable ground of epoxy package 1.
Above-mentioned execution mode only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present utility model and is implemented; can not limit protection range of the present utility model with this; all equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection range of the present utility model.
