Abstract
The utility model provides the detachable static sealing structure of a gas-insulated switchgear, which comprises a welding stud, a detachable sealing groove sidewall, a rubber sealing ring, a sealing groove sidewall and a sealing cover. The welding stud is fixedly welded on the wall of an air chamber to form a rectangular frame. The detachable sealing groove sidewall is provided with a hole corresponding to the welding stud and is connected with the welding stud through the hole. The sealing groove sidewall is welded on the sealing cover. The sealing groove sidewall is matched with the detachable sealing groove sidewall. The sealing cover is provided with a hole corresponding to the welding stud and is connected with the welding stud through the hole. The rubber sealing ring is arranged between the sealing groove sidewall and the detachable sealing groove sidewall. According to the technical scheme of the utility model, the rubber sealing ring is arranged in the two sidewalls of the sealing groove, formed by the sealing groove sidewall together with the detachable sealing groove sidewall. In this way, the displacement of the rubber sealing ring, caused by the overlarge pressure inside the air chamber, can be avoided. Therefore, the detachable static sealing structure has the advantages of reliable sealing, convenient assembly, low machining and manufacturing cost, convenient disassembly and maintenance and the like.
Description
Technical field
The utility model relates to a kind of hermetically-sealed construction, a kind of gas-filling cabinet sealing for tri-station isolating switch air chamber and breaker chamber with detachable static seal structure specifically.
Background technology
In the sealing of tri-station isolating switch air chamber and breaker chamber, need SF
6air seal, and keep certain stable gas pressure, also require the simple and convenient maintenance of assembling simultaneously, but the ubiquitous problem of current hermetically-sealed construction is, it is not only reliable but also be convenient to the effect of safeguarding that the sealing of welding class can not reach, and the hermetically-sealed construction sealing effectiveness of detachable class is poor, and leak rate is higher, check that finding is between seal and sealing ring, can produce the displacement of small distance during due to air pressure change, thereby affected reliable sealing effectiveness.
Utility model content
The purpose of this utility model be to provide a kind of seal reliable, easy to assembly, processing and manufacturing is with low cost, be convenient to the detachable static seal structure of gas-filling cabinet of demolition and maintenance.
For reaching above-mentioned technique effect, the utility model adopts following technical scheme: the detachable static seal structure of a kind of gas-filling cabinet, comprise welding screw, removable seal groove sidewall, rubber seal, groove side wall and seal cover, described welding screw is fixedly welded on and on air chamber wall, forms a rectangle frame, removable seal groove sidewall is provided with the hole corresponding with welding screw, is connected with welding screw by hole; Groove side wall is welded on seal cover, groove side wall and removable seal groove sidewall match, seal cover is provided with the hole corresponding with welding screw, is connected with welding screw by hole, between groove side wall and removable seal groove sidewall, is provided with rubber seal.
Preferably, described removable seal groove sidewall and groove side wall is contour or groove side wall height is less than removable seal groove sidewall.
The beneficial effects of the utility model:
The utility model sealing is reliable, easy to assembly, processing and manufacturing is with low cost, be convenient to demolition and maintenance, while guaranteeing that gas chamber of aeration cabinet inside is full of the pressure of sulfur hexafluoride gas and external atmospheric pressure and changes, rubber seal can not be subjected to displacement because air chamber internal pressure is excessive in welded seal groove sidewall and removable seal groove sidewall together form two sidewalls of seal groove.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is dismounting perspective view of the present utility model.
Wherein: 1, air chamber wall; 2, welding screw; 3, removable seal groove sidewall; 4, rubber seal; 5, groove side wall; 6, seal cover.
Embodiment
As shown in Figure 1, the detachable static seal structure of a kind of gas-filling cabinet, comprise welding screw 2, removable seal groove sidewall 3, rubber seal 4, groove side wall 5 and seal cover 6, welding screw 2 is fixedly welded on and on air chamber wall 1, forms a rectangle frame, removable seal groove sidewall 3 is provided with the hole corresponding with welding screw 2, is connected with welding screw 2 by hole; Groove side wall 5 is welded on seal cover 6, groove side wall 5 matches with removable seal groove sidewall 3, seal cover 6 is provided with the hole corresponding with welding screw 2, be connected with welding screw 2 by hole, between groove side wall 5 and removable seal groove sidewall 3, be provided with rubber seal 4, rubber seal 4 is pushed by air chamber wall 1 and seal cover 6, last for outer end the securing member such as plain washer, spring washer, nut fix.
In Fig. 1, left side is for being full of the air chamber inside of sulfur hexafluoride gas, right side is the air ambient of cabinet outside, rubber seal 4 is installed between air chamber wall 1 and seal cover 6, and rubber seal can not be subjected to displacement because air chamber internal pressure is excessive in welded seal groove sidewall and removable seal groove sidewall together form two sidewalls of seal groove.Thereby have sealing reliable, easy to assembly, processing and manufacturing is with low cost, be convenient to the advantages such as demolition and maintenance, generally groove side wall height is less than removable seal groove sidewall, more optimizedly removable seal groove sidewall and groove side wall are contour.
Above-described is only preferred embodiment of the present utility model.Should be understood that for the person of ordinary skill of the art, under technology enlightenment provided by the utility model, as the common practise of this area, can also make other equivalent modifications and improvement, also should be considered as protection range of the present utility model.
