Description

Technical Field

[0001] The utility model relates to the technical field of power transmission and distribution, in particular to a top cover structure of a box-type transformer substation. Background Art

[0002] The box-type substation is a factory-prefabricated indoor and outdoor compact distribution equipment that integrates high-voltage switchgear, distribution transformers and low-voltage distribution devices according to a certain wiring scheme. It organically combines the functions of high-voltage power receiving, transformer step-down, and low-voltage distribution. It is installed in a moisture-proof, rust-proof, rodent-proof, fire-proof, anti-theft, heat-insulating, fully enclosed, movable steel structure box. It operates in a fully enclosed manner and is particularly suitable for urban network construction and renovation. It is a new type of substation that has emerged after the civil substation.

[0003] The steel structure box of the box-type substation mainly includes the box body and the top cover. At present, most of the top cover structural materials of outdoor box-type substations are made of foam composite boards, which have good structural strength but poor flame retardancy. Rock wool composite boards have good flame retardancy, but low structural strength. At the same time, rock wool has strong water absorption. When used as the top cover of a box-type substation, if the top cover strength is not enough and the joint position of the rock wool composite board is not properly handled, it is easy to cause water seepage and water absorption, resulting in the expansion of the leakage surface and aggravating the leakage. Utility Model Content

[0006] Preferably, a drooping water retaining plate is provided around the top of the rock wool composite layer.

[0007] Preferably, a herringbone pressure plate is provided in the middle of the top of the rock wool composite layer.

[0008] Preferably, a fan mounting plate is also provided on the top cover frame.

[0009] Preferably, continuous sealant is applied on the upper and lower parts of the connection between the rock wool composite board and the large cap rivet.

[0010] Preferably, a waterproof shock-absorbing pad is provided under the large-cap rivet.

[0011] The beneficial effects of the utility model are:

[0012] This solution optimizes the top cover structure of a box-type substation, specifically: a rock wool composite layer is provided on the top of the top cover frame, and the rock wool composite layer is formed by splicing a plurality of rock wool composite panels. The rock wool composite panels are spliced ​​in an upward pressing manner, which is conducive to the smooth drainage of rainwater.
