Dehumidifying and dust-prevention device of generator set winding

Abstract

The invention relates to a dehumidification and dust-prevention device of generator set winding, which comprises a drying tank, a water tank, a water pipe, a first needle tube, a second needle tube, a water pumping device and an air supply device, an isolation plate dividing the water pipe into a first cavity and a second cavity is arranged in the water pipe, and the first needle tube penetrates through the middle of the isolation plate to communicate the first cavity with the second cavity; the middle of the first needle tube is communicated with the second needle tube, the second needle tube is communicated with the air supply device, the first cavity and the first needle tube are communicated with the water pumping device, and the water flow speed in the first needle tube is smaller than or equal to that in the water pipe. When water flow in the first needle tube passes through the communicating position of the first needle tube and the second needle tube, air flowing out of the second needle tube is cut into a plurality of bubbles, an exhaust port communicating with the drying tank is formed in the top of the water tank, and the drying tank is provided with a connector communicating with a generator shell. According to the invention, moisture, dust and salt in air can be effectively removed, and the service life of the generator set is prolonged.

Description

technical field [0001] The invention relates to the technical field of generator set auxiliary equipment, in particular to a moisture-removing and dust-proof device for generator set windings. Background technique [0002] During the working process of the generator set, the temperature of the motor winding will rise, in order to ensure that the motor winding works within a suitable temperature range. Usually, gas is filled into the casing of the generator, and the heat in the generator winding is taken away by the flow of gas, thereby reducing the temperature of the generator winding. The dehumidification and dust-proof device of the generator set winding can remove dust and moisture from the air before the cooled air enters the generator, so as to avoid the short circuit of the generator winding caused by dust and water vapor in the air. However, the use of moisture-removing and dust-proof devices for generator windings is very limited. For example, diesel generators used...

AI Technical Summary

Problems solved by technology

However, the use of moisture-removing and dust-proof devices for generator windings is very limited. For example, the use of diesel generators on the island is affected by the marine climate environment all year round, which makes the air on the island contain a lot of humidity and salt.

Humidity and salt in the air reduce the insulation of the electric ball winding of the generator set, thereby breaking down the insulation of the electric ball winding and making the generator set unable to operate

The existing technology uses spraying or underwater aeration to remove the salt in the air. When spraying is used, the humidity of the air will be greatly increased, which will easily cause short circuit of the generator set; when using underwater aeration, the current The volume of air bubbles produced by some aeration devices is too large, and the air bubbles are subjected to resistance after being discharged from the aeration tube. , making the volume of the bubbles further increase, which is not conducive to the removal of salt in the air
