Box-type transformer station with good ventilation and heat dissipation effect for power system

Abstract

The invention relates to a box-type transformer station with a good ventilation and heat dissipation effect for a power system. The box-type transformer station comprises a base, a box body and two ventilation devices. Each ventilation device comprises a cleaning mechanism, a drying mechanism, a horizontal tube and a vertical tube. The cleaning mechanism comprises a water tank, a water pump, a water pipe, a swing pipe, a swing component and a plurality of nozzles. The drying mechanism comprises a drying box, an air inlet pipe and an air outlet pipe. A first valve is arranged in the air inlet pipe. A second valve is arranged in the air outlet pipe. The drying box is provided therein with a lifting component, a lifting plate, a drying net, a sealing plate, a heating wire and a second fan. The box-type transformer station with a good ventilation and heat dissipation effect for a power system can wash and clean a filter screen through the cleaning mechanism to remove the dust on the surface of the filter screen, ensure smooth air circulation and facilitate ventilation and heat dissipation. Further, the drying mechanism can dehumidify the air flowing in the horizontal tube to avoid damage to the internal facilities caused by excessive humidity in the box body, which further improves the practicability of the box-type transformer station.

Description

technical field [0001] The invention relates to the field of power equipment, in particular to a box-type substation with good ventilation and heat dissipation effects for a power system. 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] In order to make the electrical equipment in the box-type substation work at a suitable ambient temperature, t...

Problems solved by technology

[0003] In order to make the electrical equipment in the box-type substation work at a suitable ambient temperature, there are usually vents on both sides of the box-type substation to facilitate the exchange of air inside and outside the substation. At the same time, a filter is installed at the vent to prevent birds Or insects enter the inside of the box, but after the box-type substation has been in operation for a long time, the surface of the filter screen is easy to absorb dust, resulting in poor air circulation and affecting the heat dissipation efficiency of the box-type substation. Not only that, but in some humid weather, the moisture in the air is easy Entering the inside of the box, the humidity inside the box will increase, and the electrical equipment in the box has strict working environment requirements. When the humidity inside the box is too high, it is easy to make the operation of the equipment unstable. damage, thereby reducing the practicability of the existing box-type substation
