Problems solved by technology

[0002] The sealing method of the existing transformer oil tank is relatively simple. Generally, a sealing ring is connected between the oil tank port and the tank cover, and then the tank cover is fixed on the oil tank by bolts. This connection method not only easily causes leakage of cooling oil, but also the sealing ring The exposed edge on the outside is easy to age, which not only easily leads to leakage but also reduces the cooling effect of the cooling oil, so that not only the sealing ring needs to be replaced frequently, but also the cooling oil needs to be replaced frequently, which causes waste. Therefore, a transformer for large transformers is required. The fuel tank sealing device to solve the above-mentioned problems

Abstract

The invention provides an oil tank sealing device for a large transformer. The oil tank sealing device comprises a box body, a box cover, a nut, a bolt, a plug board, a sealing sleeve, a boss, a sealing ring and a frame, wherein the sealing ring is disposed on the upper side surface of the box body; the frame is welded to the upper end of the outer surface of the box body; the boss is fixed to theedge of the upper side surface of the frame; the upper end of the boss extends into the sealing sleeve; the box cover and the middle portion of the rear side surface of the frame are provided with slots; the front parts of the upper and lower ends of the plug board are installed in the slots; more than two round holes 1 are disposed on the rear end of the upper side surface of the box cover; round holes 2 are disposed on the plug board directly below the round holes 1 and the upper side surface of the frame; the lower end of the bolt runs through the round hole 1 and the round hole 2 and extends to the lower side of the frame; and the nut is in threaded engagement with the lower end of the bolt. Such design improves the sealing effect of the oil tank sealing device. The oil tank sealing device provides double seal so as to achieve a good sealing effect and good protection, thereby having a long service life.
