An environmentally friendly prefabricated box-type substation

Abstract

The invention discloses an environment-friendly pre-installed box type substation. The box type substation comprises a high-voltage chamber, a transformer chamber, and a low-voltage chamber, wherein the high-voltage chamber is divided into a ventilating and radiating cabin and an electric cabin; a sulfur hexafluoride switchgear is arranged in the electric cabin; the ventilating and radiating cabin is provided with an internal air flow channel, an external air flow channel and a ventilating and purifying mechanism; the ventilating and purifying mechanism comprises a sealed shell; the inner cavity of the sealed shell is divided into an air purifying part and an air extracting part; the air purifying part communicates with the air extracting part; the air purifying part communicates with the external air flow channel; the air extracting part communicates with the internal air flow channel; a movable door is arranged in the internal air flow channel; and an active carbon filter is arranged between the air purifying part and the air extracting part. According to the environment-friendly pre-installed box type substation, the solid granular impurities in the external atmosphere can be filtered in the radiating process; and the harmful gas in the interior of the pre-installed box type substation can be purified and discharged to the air in the ventilating process as well.

Description

technical field [0001] The invention relates to a box-type substation, in particular to an environment-friendly preinstalled box-type substation, which belongs to the technical field of electric equipment. Background technique [0002] Prefabricated box-type substation is a compact complete power distribution device that combines high-voltage switchgear distribution transformers, low-voltage switchgear, electric energy metering equipment and reactive power compensation devices in one or several boxes according to a certain wiring scheme. . The main problem of the ventilation and heat dissipation system of the pre-installed box-type substation in the prior art is that, on the one hand, solid particles and impurities in the external atmosphere enter the pre-installed box-type substation during heat dissipation, which will cause the surface of the internal power and electrical components to wear or corrode. ; On the other hand, directly discharging the harmful gas, flammable a...

Problems solved by technology

The main problem of the ventilation and heat dissipation system of the pre-installed box-type substation in the prior art is that, on the one hand, solid particles and impurities in the external atmosphere enter the pre-installed box-type substation during heat dissipation, which will cause the surface of the internal power and electrical components to wear or corrode. ; On the other hand, directly discharging the harmful gas, flammable and explosive gas and corrosive gas inside the prefabricated box-type substation directly into the air will also cause harm to the surrounding environment; on the other hand, the prefabricated substation in the prior art The ventilation and heat dissipation system of the box-type substation needs to be divided into two gas pipelines with different functions, so the operation not only consumes high energy but also leads to high construction costs and occupies a large space volume
