Abstract
The utility model provides a novel nitrogen filling device which is a cylindrical tank, wherein the upper part of the tank is provided with an oil chamber, and the lower part is provided with a drying chamber. A spiral gas guiding plate and an annular gas guiding pipe are arranged in the oil chamber to increase the path and the time of nitrogen when the nitrogen passes through oil, to decrease the volume of the oil chamber and to fully filter impurities in the nitrogen. A gas inlet is arranged in the position of the drying chamber, a gas outlet is arranged in the position of the oil chamber, and valves are respectively arranged at the gas inlet and the gas outlet to control oil and gas to go in and out. A ball valve arranged at a gas outlet pipe has the function of stopping the back flow of oil. The utility model has the advantages of small size, light weight, high efficiency of moisture absorption, favorable filtering effect and convenient maintenance.
Description
The utility model relates to the nitrogen charging device of using when a kind of voltage transformer transports.
In the transformer industry transport field, during the transportation of high-power transformer main body,, adopt the capacitor oil that bleeds off in the main body in order to reduce weight, make voltage transformer be in no oily travelling position.Transformer body is exposed in the air, in order to prevent from not have the insulating part iron core that makes moist is got rusty, and retainer body insulating power are constant during transportation, will fill with drying nitrogen in fuel tank and remains on 20～30 kPas normal pressure.The nitrogen charging device that generally adopts is mainly formed, and is separated from each other by dryer, washing oil device two parts at present.Nitrogen is entered by the admission port of dryer, and nitrogen enters the washing oil device by the connection pipe again through after the dryer drying, and the washing oil device is to be used for impurity in the filter nitrogen, and the nitrogen after filtering then ejects by the air extractor duct of washing oil device.This nitrogen charging device volume is big, Heavy Weight, and is not easy to install, and less economical, be not easy to safeguard, and poor filtration effect.
In order to solve existing nitrogen charging device, volume is big, weight is big, deficiency in economic performance, poor filtration effect, be not easy to shortcomings such as maintenance, and the utility model provides a kind of later-model nitrogen charging device structure.
The technical solution of the utility model: the nitrogen airer that fills of the present utility model is the column type tank body, and top is the grease chamber, and the bottom is a dry house.Dry house is equipped with silica gel, plays hygroscopic effect; Transformer oil is housed in the grease chamber, and effect is the impurity of removing in the nitrogen; Also be furnished with spiral aeroscopic plate in the grease chamber, effect is to increase path and the time of nitrogen by oil, reduces the volume of grease chamber, fully the impurity in the filter nitrogen; Be provided with an annular ventilation flue in the grease chamber, purpose makes nitrogen at the time of grease chamber's inner filtration long enough, fully impurity screening; Ventilation flue top also is provided with a ball valve, plays the effect of air guide; Be provided with an oil outlet at You Shichu, be used for draining the oil.In addition, be provided with admission port at the dry house position, be provided with air extractor duct at the position, grease chamber, be provided with valve respectively at admission port and air extractor duct place, effect is the turnover of control oil, gas, and the ball valve at freeing pipe place also plays the effect that blocking-up oil refluxes.
