Abstract
The utility model discloses a dynamic sealing part for a high-voltage solid insulated switch. The dynamic sealing part adopts an integral thin-walled silicon rubber part with an inner hole, wherein an annular outer junction surface part is arranged on the outer edge of the inner hole, an annular inner junction surface part is arranged on the inner edge of the inner hole, and a transition part connected with the outer junction surface part and the inner junction surface part respectively is annularly corrugated by taking the inner junction surface as the center. Compared with the prior art, the dynamic sealing part has the advantages of good insulating property, good flexibility, good moisture resistance, good dustproof property, long service life and the like.
Description
Technical field
The utility model relates to electric power system equipment for power transmission and distribution technical field, in especially a kind of mesohigh switchgear as the part of movable sealing.
Background technology
The high pressure solid insulated switching installation requires solid insulation, and volume is little, not influenced by the dust, steam, air pressure etc. of external environment.Yet have also at the solid insulation pull bar place of circuit breaker polar that the dust that is subjected to external environment, steam, air pressure etc. influence may, need to solve the movable sealing of insulated tension pole chamber, design a kind of suitable dynamic seal.At present, in the high pressure switchgear, at fixed sealing type pole insulated tension pole place for preventing pollutions such as dust steam, adopt rubber ring to be added on fixed sealing type pole and the institutional framework, this frame mode can prevent to infiltrate steam, dust from fixed sealing type pole bottom to the insulated tension pole chamber, this scheme is not very desirable to the sealing effectiveness at pull bar place, and rubber ring is flexible not enough, and the life-span is limited.In gas-insulated switchgear, adopted the corrugated stainless steel tubing Sealing Technology in the insulated tension pole chamber, this scheme good sealing effect needs the space bigger, because of having adopted the sylphon seal technology identical with vacuum interrupter, cost height.
Summary of the invention
It is little that problem to be solved in the utility model provides a kind of volume, sealing, good insulation preformance, and the life-span is long, the high pressure solid insulated switch dynamic seal of low cost of manufacture.
In order to address the above problem, the technical solution adopted in the utility model is: this high pressure solid insulated switch dynamic seal, it is book wall bulk silicon rubber parts with endoporus, its outward flange is the outer joint face part of annular, inward flange is the interior joint face part of annular, links described outer joint face partly and described outer joint face transition portion partly to have with interior joint face be the annular corrugated shape at center.
Above-mentioned high pressure solid insulated switch dynamic seal, its described outer joint face part can stagger respectively with described interior joint face part and be arranged on two planes; Outside described, generally be evenly equipped with a plurality of installation through holes on the joint face part; Described thin-walled thickness be generally 4～6 millimeters; The minimum profile curvature radius R value of the ripple of described transition portion is: 5 millimeters≤R≤10 millimeters.
Owing to adopted technique scheme, the utility model beneficial effect compared with prior art is:
1, the structural design by corrugated portion, and adopt flexible good, silicon rubber manufacturing that insulation effect is good, sport life span can be improved and low-cost the manufacturing can be realized.
2, by the design of inside and outside circle bulge loop, effectively improved sealing effectiveness.
3, with corrugated stainless steel tubing sealing, compare, low cost of manufacture not only, and also volume is littler.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the vertical view of the utility model embodiment.
Embodiment
Fig. 1, this high pressure solid insulated switch dynamic seal shown in Figure 2 are to be the book wall bulk silicon rubber parts of 5 millimeters (this thickness is desirable 4～6 millimeters in other embodiments) by the wall thickness that silicon rubber is made, there is an endoporus 4 in its central authorities, the edge of endoporus 4 is interior joint face parts 3 of annular, endoporus 4 is used for being connected with the circuit breaker polar pull bar, its outward flange is the outer joint face part 1 of annular, and joint face part 1 is provided with 6 through hole 5 is installed outside; Joint face part 1 is to stagger respectively to be arranged on two planes with interior joint face part 3, figure China and foreign countries joint face part 1 is last, interior joint face part 3 is following, it is the annular corrugated shape at center that the transition portion 2 that links outer joint face part 1 and interior joint face part 3 has with interior joint face, the minimum profile curvature radius R value of the ripple of this part is 5 millimeters, in other embodiments, this value should not be greater than 10 millimeters.
Claims (3)
1. high pressure solid insulated switch dynamic seal, it is book wall bulk silicon rubber parts with endoporus, it is characterized in that: outward flange is the outer joint face part of annular, inward flange is the interior joint face part of annular, links described outer joint face partly and described outer joint face transition portion partly to have with interior joint face be the annular corrugated shape at center.
2. high pressure solid insulated switch dynamic seal according to claim 1 is characterized in that: described outer joint face part staggers respectively with described interior joint face part and is arranged on two planes.
3. high pressure solid insulated switch dynamic seal according to claim 1 and 2 is characterized in that: be evenly equipped with a plurality of installation through holes on the described outer joint face part; Described thin-walled thickness be 4～6 millimeters; The minimum profile curvature radius R value of the ripple of described transition portion is: 5 millimeters≤R≤10 millimeters.
