Abstract
A rain cover for a gas relay belongs to the rain cover for the gas relay of a substation. The rain cover is enclosed and formed by a left side vertical plate, a top plate, a right side vertical plate and a rear vertical plate. Holes used for bolt fastening are provided in the rear vertical plate. The rain cover is characterized by simple structure and convenient disassembly and assembly, can effectively prevent rainwater from entering, and can solve a problem of the false operation of gas protection.
Description
Technical field
The utility model relates to rain cover, is the rain cover that is used for transformer station's Buchholz relay specifically.
Background technology
Main transformer body and on-load voltage regulating switch Buchholz relay often cause the relay inner inlet to make moist because of raining and cause the Secondary Part DC earthing, cause light gas false alarm, even cause heavily protection misoperation tripping operation.
The utility model content
The purpose of the utility model provides a kind of Buchholz relay rain cover of easy disassembly.
This novel purpose is achieved in that a kind of Buchholz relay rain cover, is surrounded by left side vertical plate, top board, right side riser and rear side riser and forms, and have bolt on the rear side riser and connect and use the hole.
It is two that bolt on the above-mentioned rear side riser connects the use hole.
The utlity model has following characteristics:
1, simple in structure: as to make things convenient for field fabrication, can adopt sheet iron to bend and be welded, preferably adopt insulating material making such as plastic plate.
2, easy accessibility: hole on the rear side riser, adopt the M8 bolt.
3, can effectively solve rainwater gets into: according to the Buchholz relay of different structure and size; And in the rain cover bottom hole; Fix with the M8 screw, the secondary cable head is hidden in the rain cover, make the different size rain cover; Prevent that rainwater from getting into, and thoroughly solves the problem that DC loop ground connection is caused the protection malfunction.
Description of drawings
Fig. 1, Fig. 2 are respectively the stereograms of this novel different visual angles direction.
Embodiment
Fig. 1, Fig. 2 illustrate, and this novel being surrounded by left side vertical plate 1, top board 3, right side riser 2 and rear side riser 4 is formed, and have the bolt connection on the rear side riser 4 with hole 5.It is two that bolt on the rear side riser 4 connects the use hole.On-the-spot according to relay difformity size, make the different size rain cover.
