Description

A prevent waterlogging high voltage distribution cabinet for concentrating rainstorm area more

Technical Field

The invention relates to the field of power distribution cabinets, in particular to an anti-waterlogging high-voltage power distribution cabinet for a multi-concentration rainstorm area.

Background

The distribution cabinet is a final-stage device of a distribution system. The power distribution cabinet is a general name of a motor control center. The power distribution cabinet is used in the occasions with dispersed loads and less loops; the motor control center is used for occasions with concentrated loads and more loops. They distribute the power of a certain circuit of the upper-level distribution equipment to the nearby loads. This level of equipment should provide protection, monitoring and control of the load.

Waterlogging refers to a phenomenon of water accumulation disasters in cities due to strong or continuous precipitation exceeding the drainage capacity of the cities. The waterlogging is serious; the water storage volume of the lake is reduced, the water level of the lake surface is increased in the flood season, and the polder is easy to break to cause disasters; reclamation reduces the regulation and storage functions of lakes, which causes frequent flood disasters, and waterlogging is also called as water logging tolerance and is called waterlogging for short. Rainfall runoff can not be discharged in time, and farmland accumulated water is formed, so that disasters are caused to agricultural production. The rainfall intensity is larger or the duration is longer, the surface runoff can be generated, the surface ponding can be formed under the condition of lacking the drainage engineering, the crops are flooded, the normal growth is influenced if the rainfall is light, and the death is caused if the rainfall is heavy.

Often dispose numerous consumer and wiring end in the switch board, and above-mentioned consumer can produce a large amount of heats usually at the in-process of normal work, these heats if can not get timely giving off, can make the interior temperature rise of switch board, cause above-mentioned consumer to work in high temperature environment for a long time, reduce its life by a wide margin, consequently the switch board need choose for use semi-closed type to compromise self heat dispersion, in order to guarantee the normal use of the inside consumer of self, and in the concentrated area of heavy rain, very easily form in the short time and be difficult to timely excreted waterlogging, the rainwater passes through the switch board to in the louvre infiltration switch board, cause switch board interior electrical apparatus short circuit failure.
