Flood-prevention high and low voltage power distribution cabinet

Abstract

The invention discloses a flood-prevention high and low voltage power distribution cabinet, and relates to the technical field of power equipment. The flood-prevention high and low voltage power distribution cabinet comprises a box body, an air cushion and a guide rod, wherein the box body comprises an upper cavity, a guide hole, a transverse groove and a lower cavity; the upper cavity is arrangedat the upper part of the box body; the lower cavity is arranged at the lower part of the box body; the guide hole is formed in a vertex angle of the box body; the transverse groove is formed in an outer side wall of the lower cavity; the air cushion is arranged in the lower cavity body; the upper end of the guide rod is arranged in the guide hole and the lower end is fixed on the ground through abearing; and the inner surface of the guide hole and the outer surface of the guide rod are both provided with thread. The structure is simple, the use is convenient, the electric device in the powerdistribution cabinet can be effectively protected, the normal operation is ensured maximally, and the loss is reduced.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a high and low voltage power distribution cabinet for flood protection. Background technique [0002] As the name implies, the high and low voltage power distribution cabinet is the power distribution equipment used for power distribution, control, metering and cable connection in the power supply system. Generally, power supply bureaus and substations use high-voltage switchgear, and then step down the low-voltage side through transformers. Lead to the low-voltage power distribution cabinet, the low-voltage power distribution cabinet is connected to each power distribution board, control box, and switch box, and there are some switches, circuit breakers, fuses, buttons, indicators, meters, wires and other protection devices inside. A device that is assembled into a power distribution device that meets the design function requirements. Commonly known as: high and low ...

AI Technical Summary

Problems solved by technology

[0004] Due to the wide use of power distribution cabinets, their operating conditions are greatly affected by environmental factors. Especially for some small-capacity box-type stations, it is often encountered that the cabinets are damp and water ingress, which will damage the electrical components in the cabinets. It will cause adverse effects, make it unable to operate normally, and fail to meet the maintenance-free period target required by the design. Moreover, the weather conditions in many cities are relatively bad, and natural disasters such as floods and heavy rains often occur, and usually the water level is relatively high. A large amount of water will If it enters the distribution cabinet, the excessively high water level will cause damage to a large area of ​​the distribution cabinet, resulting in difficulties in maintenance and unpredictable economic losses.
