Visual transparent transformer breathers Shu transformer oil cup transparent respirator

The role of transformer breathers: the transformer operation respirator breathing process: With the temperature rise, the volume of oil in the expansion tank conservator excess oil into the oil chamber (referred to as "oil chamber"), change the oil chamber volume big, gas chamber while the conservator (the "gas chamber") within the marginalized into the atmosphere through a respirator; when the oil tank is lowered, the oil volume contraction, the oil chamber of oil into the tank, while the atmosphere through Respirator sucked into the gas chamber. The oil level from the oil level in the oil chamber of the meter display. Oil level gauge pointer is generally tube-type oil level gauge and oil-level gauges with small capsules, which are strictly isolated from the atmosphere. Oil level gauge indicates the actual pressure inside the tank is appropriate. In addition to the expansion of transformer radiator outside, whether distribution transformers, transformer or medium-sized and even large transformers, are equipped with breathing apparatus, it is a transformer chamber gas exchange with the outside world must pass through the barrier, the gas enters the transformer From dry filter effect, its role is essential. When the respirator clogging or silica contents when there is a greater degree of deliquescence, the safe operation of the transformer threat. As substation operation personnel, operation of the respirator must be diligently patrol, observe, carefully maintained. Running respirator packed silica gel with a blue or white. Look at the color gel drying blue or light blue glass-like particles, when adsorbed moisture becoming light red, white silica gel when wet gradually turn pink or brown discoloration when nearly 1/5 of hygroscopic agent, should be replaced, and pay attention to cleaning the lower part of the respirator seal, replace the cleaning oil. Maintenance matters respirator should be noted: 1, operation maintenance, replacement silicone respirator must be kept a safe distance from safety regulations, or should power be. 2, according to operating procedures transformer, when the oil level gauge oil abnormally elevated or abnormal respiratory system, the need to fight the open air or drain valves, heavy gas should change the access signal. 3, the replacement of silica gel should be good weather, air moderately hours. Respirators should be removed immediately after the breathing tube head with a clean sheet of plastic wrap to prevent moisture from entering. 4. Replace the silica gel to be cleaned at the same time replace the seals in transformer oil (usually routine visits to check the transformer should be based on the provisions of the timely detection and timely replacement), seal oil surface should be higher than the blocking balloon (about 2/3), or from the Seal less effect. 5. Replace the silica gel should do self-protection, if silicone into the eyes, need plenty of water and seek medical treatment as soon as possible. Blue Silicone since the content of a small amount of cobalt oxide, toxic, due to avoid food contact and inhalation of the mouth, such as the occurrence of poisoning should immediately seek medical treatment. 6, the replaced silicone renewable. Drying regeneration should be careful to raise the temperature gradually, so as not to cause severe drying silicon particles burst, lower recoveries. When silicone baking for regeneration, the temperature is too high will cause changes in the pore structure of the silica gel adsorption effect significantly reduces the impact value. For blue gel indicator or color gel, desorption regeneration temperature should not exceed 120 ℃, otherwise they will be oxidized color developing agent progressively lose coloration. Silica gel regenerated should generally be screened to remove fine particles, so that the particles uniformly. Dried for use.
