Folding rain cover suitable for outdoor cabinet of transformer station

Abstract

The present invention provides a folding rain cover suitable for an outdoor cabinet of a transformer station. The folding rain cover comprises a main body and a connection piece; the main body comprises a plurality of fan ribs and a cover surface; the connection piece comprises a fan nail; the fan nail and a cabinet body are oppositely fixed at one side where a hinging portion of the cabinet bodyand a cabinet door is located, and the lowest point of the fan nail is higher than the top end of the cabinet door; the fan ribs are distributed in a lamination mode, and one ends of the fan ribs arehinged to each other by taking the fan nail as an axis; one end, far away from the fan nail, of one fan rib A located at the lowest portion of the fan ribs is oppositely slidingly and rotationally connected with the cabinet door; when the cabinet door is completely opened, the main body is located at a completely unfolded state, the fan ribs are distributed in a sector-shaped mode, and the cover surface is laid and fixed on the fan ribs; and when the cabinet door is completely closed, the main body is located in a completely folded state, the cover surface is in a folding-layer shape, and theuppermost layer of the cover surface is relatively fixed with the cabinet body. The folding rain cover suitable for an outdoor cabinet of a transformer station is convenient and rapid and reliable, and can further guarantee safety production of a transformer station.

Description

technical field [0001] The invention belongs to the field of daily maintenance of substation equipment, and in particular relates to a foldable awning suitable for outdoor cabinets of substations. Background technique [0002] There are many types of outdoor cabinets in substations, including terminal boxes, central control boxes, mechanism boxes, etc. The circuit formed by the electronic components and terminals in these cabinets ensures the protection action of the substation, signal transmission and other functions. Stable operation plays a vital role. If the components and terminals in the box get wet, it is very likely to cause the protection device to malfunction or refuse to operate, resulting in line tripping and equipment damage, which seriously threatens the stable operation of the power grid. Usually, on rainy days, substation operation and maintenance personnel will not easily open the outdoor cabinets, just to prevent rainwater from pouring into the cabinets, c...

AI Technical Summary

Problems solved by technology

At present, the outdoor cabinets of substations do not have actual rain-proof facilities. Some outdoor cabinets are equipped with rain-proof eaves similar to roof eaves, which can prevent rainwater from flowing down the top of the cabinet and dripping into the cabinet to a certain extent when the cabinet door is opened. Inside the cabinet, however, due to the short eaves, it is usually only 5cm wider than the cabinet at most, which cannot prevent rainwater from directly pouring into the cabinet under the action of wind when the door is opened
