Abstract

The invention discloses a box-type transformer and a ventilation control method thereof. The box-type transformer comprises a main controller, a box body, a fan, a rotating brush and a double-layer filter screen; a plurality of ventilation openings are formed in the box body; the plurality of ventilation openings are distributed up and down; each ventilation opening is sequentially provided with a double-layer filter screen, a rotating brush and a fan from the outer side to the inner side; the inner layer of the double-layer filter screen is a fine filter screen, and the outer layer is a coarse filter screen; the rotating brush abuts against the double-layer filter screen and is in transmission connection with the fan through a ratchet mechanism; when the fan rotates in the forward direction, the ventilation openings are in an air outlet state; when the fan rotates in the reverse direction, the ventilation openings are in an air inlet state; the ratchet mechanism is used for limiting reverse rotation of the rotating brush; and the main controller is arranged in the box body, is electrically connected with the fan and is used for controlling the start and stop of the fan. The double-layer filter screen is arranged on the ventilation openings of the box body, and the ratchet mechanism is connected with the rotating brush and the fan, so that dust and flying catkins can be effectively prevented from entering the box body.

Description

technical field [0001] The present application relates to the technical field of transformers, and in particular, to a box-type transformer and a ventilation control method thereof. Background technique [0002] Box-type transformers refer to the transformers in which the traditional transformers are centrally designed inside the box-type shell, and are mostly located in industrial areas. Taking the cotton spinning industrial area as an example, a lot of cotton wool will be blown out of the factory by the factory fan, causing a large amount of dust flying in the air, which will cause obvious pollution and adhesions on the power distribution equipment in the box transformer. And when the air becomes humid, these flying flakes can absorb moisture, thereby reducing the insulation strength of the equipment, and even causing the circuit to trip. [0003] The existing box-type transformer housing only has vents and dust filters, which cannot meet the ventilation and dust-proof st...
