Abstract

The invention provides an anti-condensation system for an underground transformer substation equipment room. The anti-condensation system comprises a monitoring mechanism and a control mechanism arranged in the equipment room, a first condensation mechanism arranged at the inner lower part of the equipment room, a heating mechanism arranged in the equipment room in correspondence to equipment, anda second condensation mechanism arranged in the equipment room and located above the equipment in the equipment room. The anti-condensation system of the invention can monitor humidity in the underground transformer substation equipment room, separate moisture from the air by condensation, change the position of water drop condensation, prevent the equipment from condensation and greatly improvethe safety of the equipment during operation.

Description

technical field [0001] The invention relates to the technical field of power equipment operation and maintenance, in particular to an anti-condensation system between equipment in an underground substation. Background technique [0002] With the gradual increase of surface buildings, many substations in the city have adopted the design scheme of underground substations, so the number of underground substations has gradually increased. However, underground substations face many problems, especially in the southern region, where it is cold and humid in winter, and the temperature of underground substations will be lower and the humidity will be higher. Adhering to water droplets will cause damage to equipment, so it is very important to prevent condensation in underground substations. [0003] The patent with publication number 201708467U discloses an environment improvement control system for underground substations, including a humidity control device, an exhaust emission s...
