A prefabricated substation with self-circulating heat dissipation vertical span structure

Abstract

The invention discloses a prefabricated substation with a self-circulating heat dissipation vertical span structure, which belongs to the field of substation equipment, and can realize the form of pre-installed self-circulation heat dissipation vertical span components, which can be used to directly dissipate the transformer generated during the working process. The heat generated can be quickly transferred to the outside air, mainly relying on the principle of endothermic vaporization and exothermic liquefaction of cooling water to realize self-circulation heat dissipation, and at the same time, an expandable heat dissipation breathing tube is installed to accelerate the process of exothermic liquefaction. Expand the contact area with the external environment. On the other hand, use the force generated by "breathing" to accelerate the flow speed of the nearby air, thereby comprehensively improving the heat dissipation performance. In addition, it can also collect and use natural rainwater and dew for auxiliary heat absorption and cooling. Realize The unpowered transformer in a closed environment can effectively dissipate heat to ensure the normal operation and good service life of the transformer.

Description

technical field [0001] The invention relates to the field of substation equipment, more specifically, to a prefabricated substation with a self-circulating heat dissipation vertical span structure. Background technique [0002] The prefabricated substation is electrically connected through cables or busbars. All high and low voltage power distribution devices and transformers are conventional stereotyped products. The prefabricated substation has the advantages of small size, small footprint, light weight, low cost, and reliability. "Box-type substation" or "prefabricated substation. It 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. That is to organically combine functions such as transformer step-down and low-voltage power distribution, and install them in a moisture-proof, rust-proof,...

AI Technical Summary

Problems solved by technology

Since the European-style box-type transformer is to install the transformer and ordinary high-voltage electrical equipment in the same metal casing, the room temperature of the transformer is very high, which causes difficulty in heat dissipation, seriously interferes with the normal working load of the transformer, and shortens the service life of the transformer.
