High-voltage and low-voltage prefabricated substation anti-ice drop top cover structure

Abstract

The invention discloses a high-voltage low-voltage preassembling type transformer substation ice-block-falling-resistant top cover structure. The high-voltage low-voltage preassembling type transformer substation ice-block-falling-resistant top cover structure comprises a frame, a cover plate and top covers, the cover plate is arranged on the frame, the top covers are arranged above the cover plate, a plurality of inversed-U-type plates are arranged on the cover plate, the upper end faces of the inversed-U-type plates and the top covers are respectively provided with mutually-corresponding connecting holes to enable the top covers to be capable of being installed and fixed on the inversed-U-type plates in a threaded connection mode, when ice blocks fall off, the top covers on the outer layer are smashed firstly, therefore, the cover plate on the lower layer is protected, the situation that the top covers are damaged by the ice blocks so that equipment is directly exposed in the outdoor environment is avoided, and the design protection requirement is met. The cover plate is of an eave type structure, the two sets of top covers cover two slopes of the cover plate respectively, the cover plate of the eave-type structure and the top covers are reasonable in structural layout, the structural strength is high, when the top covers are damaged, the top covers can be directly disassembled and replaced through threaded connection, and the top covers are rapid and convenient to maintain. Furthermore, a plurality of strengthening plates are arranged at the bottoms of the top covers, and the structural strength of the top covers is further strengthened.

Description

technical field [0001] The invention relates to a top cover structure, in particular to a high-voltage and low-voltage prefabricated substation anti-ice block drop-off top cover structure. Background technique [0002] As the saturation of the wind power industry is gradually balanced, many wind farms are gradually shifting to areas with harsher environments. In some areas, the temperature is low, the temperature difference is large, the humidity is high, and the wind and sand are large. Especially when there are extreme weather changes in the area, the temperature difference between day and night changes greatly. Thick layers of ice often condense on the wind turbine blades, and when the wind becomes stronger or the sun shines for a longer time, the ice cubes begin to melt and fall, falling about 70m from the ground. The high-voltage / low-voltage prefabricated substation is usually installed under the wind turbine , while the structure design of the traditional high-voltage / ...

[0002] As the saturation of the wind power industry is gradually balanced, many wind farms are gradually shifting to areas with harsher environments. In some areas, the temperature is low, the temperature difference is large, the humidity is high, and the wind and sand are large. Especially when there are extreme weather changes in the area, the temperature difference between day and night changes greatly. Thick layers of ice often condense on the wind turbine blades, and when the wind becomes stronger or the sun shines for a longer time, the ice cubes begin to melt and fall, falling about 70m from the ground. The high-voltage / low-voltage prefabricated substation is usually installed under the wind turbine , while the structure design of the traditional high-voltage / low-voltage prefabricated substation roof structure is unreasonable. When the ice cube falls from a high altitude under the action of gravity, it is easy to deform the roof or even directly damage it, and replace it after damage. very troublesome
