Abstract
The utility model belongs to the manufacturing field of the integral parallel capacitor, in particular provides a sealing structure of the integral parallel capacitor. The sealing structure comprises a box body with a box edge (1), a box lid and a sealing washer. The sealing structure is characterized in that a sealing groove (2) is arranged on the surface of the box edge (1), the sealing washer is arranged in the sealing groove (2), and the box lid is fixedly connected with the box edge (1) via the sealing washer. The sealing structure can be widely used in the capacitor products with assembled structure and higher requirement of sealing performance.
Description
Technical field
The utility model belongs to assembling shunt capacitor and makes the field, and a kind of assembling shunt capacitor hermetically-sealed construction particularly is provided.
Technical background
Assembling shunt capacitor is a convenient for maintaining, its case lid all adopts fabricated construction, sealing relies on the seal washer that exposes folded between case lid and the case edge to finish, seal washer is exposed in the air, and the peripheral end face on case lid and case edge is concordant, and rainwater is easy to infiltrate interplanar slit, move a period of time like this after, ageing failure appears in seal washer easily, and causes the capacitor leakage of oil.
The content of invention
The object of the present invention is to provide and a kind ofly can prevent rainwater, delay the aging assembling shunt capacitor hermetically-sealed construction of seal washer, solve the leakage of oil problem that occurs because of the seal washer accelerated ageing.
For solving the problems of the technologies described above, the technical solution of the utility model is: this assembling shunt capacitor hermetically-sealed construction, the casing, case lid and the seal washer that comprise band case edge, it is characterized in that, described case offers seal groove along the surface, seal washer is arranged in the sealing groove, and case lid is fastenedly connected by seal washer and case edge.
The periphery of described case lid is stretched out the periphery on case edge.
The upper surface on described case edge exceeds cabinet wall.
Because along having designed a hiding seal groove, seal washer is contained in the hiding seal groove, from not seeing seal washer in appearance, prevents that seal washer is aging because of exposing to the weather at case; Make the periphery of case lid stretch out the periphery on case edge, the upper surface on case edge exceeds cabinet wall, prevents that rainwater from infiltrating the slit between case lid and the case edge; Casing along being fastenedly connected with case lid, has solved the problem of case lid distortion ponding by case.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described
Fig. 1 is that case of the present utility model is along structure chart
Embodiment
The case of assembling shunt capacitor welds with tank wall along 1, and case exceeds cabinet wall 3mm along 1 upper surface.With reference to accompanying drawing 1, along Zhou Kaishe seal groove 2 in the surface, the width of seal groove 2 and the degree of depth and seal washer adapt, and decide according to the decrement and the compressed coefficient of used seal washer near case.The periphery of case lid is stretched out the periphery 20mm of case along 1, has avoided rainwater to infiltrate case lid and the case slit between 1.During assembling, seal washer is installed in case along in 1 the seal groove 2, again with bolt with case lid and case along 1 fastening, till case lid and case are combined closely along 1.
The utility model can be widely used in the capacitor product with fabricated construction that sealing property has relatively high expectations.For example be applied in the assembling shunt capacitor of 10kV and 35kV, fundamentally solved the assembling shunt capacitor product because of the aging leakage of oil problem that occurs of seal washer, and its appearance property is improved greatly.
Claims (3)
1, a kind of assembling shunt capacitor hermetically-sealed construction, comprise casing, case lid and the seal washer of band case, it is characterized in that described case offers seal groove (2) along (1) surface along (1), seal washer is arranged in the sealing groove (2), and case lid is fastenedly connected along (1) by seal washer and case.
2, assembling shunt capacitor hermetically-sealed construction according to claim 1 is characterized in that, the periphery of described case lid is stretched out the periphery of case along (1).
As assembling shunt capacitor hermetically-sealed construction as described in the claim 2, it is characterized in that 3, described case exceeds cabinet wall along the upper surface of (1).
