Protective cover additionally arranged on outdoor box body of transformer substation

Abstract

The invention provides a protective cover additionally arranged on an outdoor box body of a transformer substation. The protective cover comprises a protective cover box body and a protective cover top cover. A cavity for accommodating the transformer substation outdoor box body is formed in the protective cover box body; a first opening communicated with the cavity is formed in the outer top endof the protective cover box body; a through hole communicated with the cavity is formed in the outer bottom end of the protective cover box body; and a second opening communicated with the cavity is formed in the outer side wall of the protective cover box body. The through hole is in sealed connection with a line entering and exiting the outdoor box body of the transformer substation through a first sealing piece; a cabinet door capable of covering or exposing the second opening is rotationally mounted on the edge of one side of the second opening; the cabinet door is in sealed connection with the second opening through a second sealing piece when covering the second opening; and the protective cover top cover covers the first opening and is connected with the protective cover box body ina sealed mode through a third sealing piece. The protective cover can realize moistureproof and waterproof effects of the outdoor box body, so that the problems of untight sealing and the like causedby rusting and deformation of the box body are fundamentally solved; and modification can be carried out without power failure.

Description

technical field [0001] The invention relates to the technical field of substation outdoor box body protection, in particular to a protective cover installed on the substation outdoor box body. Background technique [0002] Based on construction difficulty and cost considerations, most of the primary high-voltage equipment in the substation is installed outdoors, and the terminal boxes and on-site control cabinets matching the primary high-voltage equipment are installed in the nearby high-voltage site. Due to long-term exposure to harsh environments such as wind, sun and sun, the cabinet will be deformed and rusted after a certain period of operation. If the cabinet is not tightly sealed, external moisture will enter the cabinet, or even water will leak. There are a large number of secondary circuits for controlling and monitoring primary equipment in the cabinet. Each circuit will generate a certain amount of heat when it is powered on for a long time. The space in the cabi...
