Abstract
The utility model relates to a vacuum transition tank which prevents transformer oil from entering a vacuum pump when oil is injected into an oil-immersed type transformer in a vacuum manner. The vacuum transition tank comprises a tank body, a tank cover, an air inlet valve, an air exhaust valve and an oil drain valve, wherein the tank body is capable of resisting vacuum; the tank cover is arranged at the upper part of the tank body and connected with the tank body in a sealing manner; the air inlet valve is arranged at upper part of the tank body and connected with a transformer oil storage cabinet by a pipeline; the air exhaust valve is arranged on the tank cover and connected with a vacuum pump by a pipeline; the oil drain valve is arranged at the lower part of the tank body; and a magnetic turning plate type oil level gauge is arranged on the wall of the tank body. The vacuum transition tank has the characteristics of reasonable structure, long service life and can prevent the transformer oil from entering the vacuum pump.
Description
Technical field
The utility model prevents that transformer oil from entering the vacuum transition jar of vacuum pump when relating to a kind of oil-filled transformer vacuum oil.
Background technology
Large oil immersed formula voltage transformer needs vacuum oil after assembling is finished, note the interface height that can not allow the voltage transformer oil level surpass vacuum-pumping pipeline during vacuum oil, not so can be with in the transformer oil suction vacuum pump, and the infringement vacuum pump.Cause in the transformer oil suction vacuum pump because neglect for preventing, the situation of infringement vacuum pump, can on pipeline, increase the transparent U-shaped pipe of two ends band valve vacuum-resistant, this U-shaped pipe is generally glass, just in case the voltage transformer oil level surpasses the interface height of vacuum-pumping pipeline when causing oiling because of carelessness, the oil-feed of U-shaped glass tube only need be closed U-shaped glass tube and vacuum pump bonded assembly valve, can prevent into transformer oil and enter in the vacuum pump, the infringement vacuum pump.But the U-shaped glass tube belongs to fragile, and is very easily broken in the use, also very dangerous to the operator.Shortcoming in view of the U-shaped glass tube, also have and use the vacuum transition pipe to replace the U-shaped glass tube, this vacuum transition pipe is generally the leakproof tank that steel plate is welded, for guaranteeing that it can vacuumize, general uneasy dress oil level gauge, because it is this kind oil level gauge is generally glasswork, frangible and be difficult to bear vacuum pressure.
Summary of the invention
The utility model provides a kind of rational in infrastructure in order to overcome above-mentioned defective, and long service life prevents that transformer oil from entering the vacuum transition jar of vacuum pump.
The technical solution adopted in the utility model is: a kind of vacuum transition jar, it is characterized in that: comprise tank body, cover, air inlet valve, blow off valve and oil cock, described tank body is for tolerating the tank body of vacuum, described cover be arranged on tank body top and with tank body for being tightly connected, described air inlet valve is arranged on the tank body and by pipeline and is connected with the voltage transformer oil conservater, described blow off valve is arranged on the cover and by pipeline and is connected with vacuum pump, described oil cock is arranged on the bottom of tank body, and the wall of tank body is provided with magnetic turnover plate type oil level gauge.
The utility model is installed between voltage transformer and the vacuum pump, and when vacuumizing, in a single day transformer oil is drawn out of, and can not enter vacuum pump and can be introduced in the tank body of the present utility model, prevents to damage vacuum pump, improves service life; Magnetic turnover plate type oil level gauge is set on tank body can be convenient to observe oil mass in the tank body, and discharge by the oil cock on the tank body, easy to operate, economical and practical.
Description of drawings
Fig. 1 is a scheme drawing of the present utility model.
The specific embodiment
Now in conjunction with the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, mainly comprise tank body 1, cover 2, air inlet valve 3, blow off valve 4 and oil cock 5, described tank body 1 be for can tolerating the tank body 1 of vacuum, and tank body 1 can be for cylindrical or square etc.Described cover 2 be arranged on tank body 1 top and with tank body 1 for being tightly connected, be provided with seal ring between cover 2 and the tank body 1 in the present embodiment.Described air inlet valve 3 is arranged on the tank body 1 and by pipeline and is connected with the voltage transformer oil conservater, described blow off valve 4 is arranged on the cover 2 and by pipeline and is connected with vacuum pump, described oil cock 5 is arranged on the bottom of tank body 1, and the wall of tank body 1 is provided with magnetic turnover plate type oil level gauge 6.
When the utility model uses each pipeline connection is finished, all the other two valves all are opening except that oil cock 5, undertaken by common program when vacuumizing during vacuum oil, when the voltage transformer oil level surpasses the interface height of vacuum-pumping pipeline, transformer oil or enter in the tank body 1, can not enter in the vacuum pump, prevent the infringement of vacuum pump.More for a long time, can close two valves by the oil level in the observation oil level gauge 6 discovery tank bodies 1, after the vacuum oil program of transformer oil is finished, reclaim transformer oil by oil cock 5 more then.
The utlity model has rational in infrastructurely, long service life prevents that transformer oil from entering the vavuum pump characteristics.
