Transformer power transformer breathers Shu Shu silicone oil pillow transformer tank breathers

Grid and medium-sized transformers generally have a respirator. This respirator is a glass container, poured into a discoloration of silica gel desiccant is provided a transformer oil containing oil cup at its lower end. Filled with transformer oil in the cup into the main change to filter out dust and air through the transformer oil, and then filtered through silica gel wherein the water, so that the last change into the main air inside is dry clean, can serve to prevent the insulating oil aging. Before moisture absorbent not absorbent, it was blue, after loading respirator bright color, easy to observe. If the moisture absorbent draw enough moisture to become white saturated. Duty by silica gel color changes in breathing apparatus, to determine whether silicone deliquescence. When the silicone part accounted for more than one-third of the whole, it should be replaced. When replacing the silica gel, it should pay attention to the role of the following aspects: (1) Replace the silica gel should be in fine weather, and keep a safe distance from live parts. (2) the amount of silica gel loaded with two-thirds of the volume of the appropriate respirator. (3) silica gel can be used for down tablespoons stir heating and drying, it can continue to be used, in order to reduce operating costs. (4) the application of the oil cup oil replacement, and enough qualified new oil. (5) should be re-gas protection reroute signals (6) should remove the ventilator tube blocked even prevent recovery of air (7) replaced the dry silica gel, it should not make the oil seal over the mouth of breath within and the respirator seal. In the daily visits to check, we should observe the color changes in breathing silica gel, especially during the rainy season, the air humidity, speed deliquescence silicone, silicone discoloration, it should be replaced. Oil cup respirator should be installed under an appropriate degree. Over-tighten, breathing does not work; you can not afford to spin too loose filtered air. For an idle instrument transformers and 66kV current transformer, the respirator should also be timely check and replace the moisture absorbent and oil, because as the temperature changes, the oil in the vessel also changes, respiration continues. This time as neglect checking respirator, these devices are easy to make damp, resulting in undue loss.
