Background
The transformer breather is a protection device connected with a transformer conservator, and mainly has the functions of communicating air in the transformer conservator with the outside, increasing the oil temperature and expanding the volume when the transformer runs, and exhaling the gas in the transformer body; the oil temperature is reduced, the volume is reduced, and external air is sucked, so that the internal air pressure and the external air pressure are the same. In addition, the respirator tank is internally provided with silica gel which is used as an adsorbent to absorb moisture in the air and prevent the moisture in the outside air from entering the oil conservator, so that the insulation strength of the transformer oil is reduced, and the tank bottom of the respirator is provided with an oil cup which is filled with the transformer oil and used as an oil seal to prevent impurities in the air from entering the oil conservator through the respirator.
Most transformers are located outdoors, the respirator runs in a severe environment for a long time, and silica gel is easy to discolor and deliquesce and can weaken or lose adsorption. Should change when the silica gel portion of weing can reach whole two-thirds. In addition, the transformer oil in the oil seal is saturated due to absorption of moisture, dust, impurities and the like and ordinary oxidation, and the transformer oil also loses adsorption performance and needs to be replaced in time. When the oil cup is full of oil dirt on the surface of the oil cup, the oil level cannot be clearly seen or the filter opening of the respirator is blocked, the transformer oil needs to be replaced immediately, and the oil cup is cleaned. In addition, the respirator is blocked to cause internal negative pressure, and the respirator causes a large amount of air inflow of the main transformer body in serious conditions, so that the oil level is reduced, gas protection action is caused, and the main transformer is tripped. According to different operating environments, each breather may need to be replaced for 3 months, so that replacement of silica gel and oil-sealed transformer oil of the breather is routine maintenance work.
At present, the maintenance and replacement of the respirator face some problems, firstly, the respirator is frequently disassembled, the sealing is not in place, the sealing between the upper glass and the lower glass of the respirator tank and the seat is not tight, and the sealing of the respirator flange is not tight; secondly, the replacement of the silica gel of the respirator is time-consuming and labor-consuming, the removal and cleaning are carried out every time, and at least two persons are probably needed for more than 1 hour for replacing the silica gel, replacing the oil seal transformer oil and then installing the respirator. Thirdly, the silica gel tank and the oil cup are not cleaned in place, the cleaning process consumes long time, and environmental pollution is easily caused. Fourthly, the respirator is easy to be damaged because the respirator has certain weight (about 10 kilograms) and the hands of workers have oil when being disassembled and assembled.
