Description

Adjustable transformer cooler cleaning device

Technical Field

The invention relates to the technical field of transformer coolers, in particular to an adjustable cleaning device for a transformer cooler.

Background

At present, two modes are generally adopted for flushing a large transformer cooler at home and abroad: air washing and water washing. In general, in the routine maintenance work of the large transformer, the large transformer cooler is flushed once every half year or when necessary.

Compared with a gas flushing mode, the water flushing mode has high requirements on human resources and equipment personal safety, but the flushing effect of the water flushing mode is better and superior, under the water flushing mode, at least 4 people are generally needed for flushing, the flushing time of each group of coolers is different from 40 minutes to 60 minutes, power-off and electric part waterproof measures are needed before flushing, if electrified water flushing is selected, measures for preventing water columns from impacting high-voltage lines are needed, and the mode is extremely high in safety risk. Under the air flushing mode, generally, 3 people are needed to carry out flushing work at least, the flushing time of each group of coolers is 30-50 minutes, measures for preventing air pipes from irregularly moving due to overhigh air pressure need to be taken during flushing, the air flushing mode is easier to realize under the condition that equipment is electrified, and the safety risk is lower. In addition to the above problems, there are safety risks associated with high-altitude operations when both of the two flushing methods are applied to the flushing process of the large transformer cooler. And when the flushing point is close to the top of the cooler, the risk that the flushing medium or the flushing pipeline contacts the high-voltage live line exists, and the equipment and personal safety are seriously threatened. Particularly, after the cooler in the transformer is used for a period of time, dust is deposited on the surface of the cooler, so that the cooling efficiency is greatly influenced, and the cooler is very easy to damage.

The two kinds of methods of gas washing, water washing in addition waste time and energy, and is with high costs, and there is certain safe risk in the work, uses the muddy water that high-pressure water washed the production extremely difficult control, and muddy water splash easily causes the sleeve pipe to pollute and dodge, safety risks such as electric shock to electrified position, and the water or the compressed air that maintainer used in addition in the electrified washing all have higher pressure, and misoperation all can increase the potential safety hazard that the high altitude falls.
