Abstract
The invention relates to the technical field of switch equipment of a power system, in particular to a three-station isolating switch. The three-station isolating switch is provided with an epoxy resin shell with a cavity; the front end of the cavity of the epoxy resin shell is provided with an upper wire-out seat, and the bottom of the epoxy resin shell is provided with a lower wire-out seat; a movable contact, a middle static contact and an insulating screw rod are arranged in the epoxy resin shell; the middle static contact is connected with the lower wire-out seat; the insulating screw rod drives the movable contact to move; one end of the movable contact is connected with the upper wire-out seat; the epoxy resin shell is also provided with a sealing plate; a cavity in which clean and dry air serving as an insulating medium can be filled is formed in the epoxy resin shell; and a touch ground layer is sprayed on the epoxy resin shell. The three-station isolating switch has a function of preventing safety accident caused by unexpected touch, ensures that the insulating reliability and safety reliability are improved, and is environment-friendly.
Description
Technical field
The present invention relates to the technical field of electric power system switchgear, especially a kind of tri-station isolating switch.
Background technology
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 problem to be solved in the present invention is: overcome the deficiency in the prior art, a kind of reliability height, tri-station isolating switch that fail safe is good are provided.
The technical solution adopted for the present invention to solve the technical problems 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 invention has the beneficial effects as follows: insulating reliability of the present invention, security reliability all are improved, and do not use environmentally harmful gas, the protection environment.
Description of drawings
The present invention is further described below in conjunction with drawings and embodiments.
Fig. 1 is structural representation of the present invention.
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.
The present invention is further illustrated by reference to the accompanying drawings now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present invention in a schematic way, so it only shows the formation relevant with the present invention.
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 2, 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 present invention 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 invention and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that spirit essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
