A box -type substation with a moisture -proof and cooling function

Abstract

The invention relates to a box-type substation with dampproof and heat radiating functions, comprising a base, a box body and two ventilation ducts, an opening is formed in the box body, a box door isarranged in the opening, a PLC, an antenna, a dampproof mechanism and a starting mechanism are arranged in the box body, a ventilation mechanism is arranged in each ventilation duct, the dampproof mechanism comprises a water draining component and two dampproof components, each dampproof component comprises a translation unit, a translation plate, an air pump, a sandbag, a fixed bin and four telescopic units, each telescopic unit comprises a cylinder and a piston, and each ventilation mechanism comprises a filter screen, a cleaning component, a lifting plate, a lifting component, a connectingplate, a supporting rod and a sealing plate. The box-type substation with dampproof and heat radiating functions can prevent a large amount of rainwater from being permeated into the interior of thebox body by virtue of the dampproof mechanism and timely discharges a small amount of rainwater permeated into the interior of the box body, thus safe operation of electric appliances and facilities inside the box body is guaranteed; besides, the ventilation ducts are controlled to be opened or closed by virtue of the ventilation mechanisms, heat can be conveniently and timely transferred, the electric appliances and facilities operate in an appropriate temperature environment, and practicability of equipment is improved.

Description

technical field [0001] The invention relates to the field of power equipment, in particular to a box-type substation with moisture-proof and heat-dissipating functions. Background technique [0002] Box-type substation is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device. It is a factory prefabricated indoor and outdoor compact power distribution equipment arranged according to a certain wiring scheme, which is about high-voltage power receiving, transformer step-down, low-voltage Functions such as power distribution are organically combined and installed in a fully enclosed movable steel structure box. Mechatronics is integrated and fully enclosed. It is especially suitable for urban network construction and transformation. It is a brand-new emerging after civil substations substation. [0003] However, in the existing box-type substation, because the internal electrical facilities work in a closed environment, the heat g...

AI Technical Summary

Problems solved by technology

[0003] However, in the existing box-type substation, because the internal electrical facilities work in a closed environment, the heat generated gradually accumulates and cannot be dissipated, resulting in a gradual increase in the temperature in the box-type substation. Not only that, but the existing box-type substations generally have poor moisture-proof performance. When heavy rain occurs, rainwater will easily seep into the box through the gap in the box door, causing internal electrical short circuit, resulting in equipment damage. As a result, the practicability of the existing box-type substation is reduced
