Description

Technical Field

[0001] The utility model relates to a transformer oil storage cabinet device, in particular to a transformer oil storage cabinet device based on external oil. Background Art

[0002] The transformer oil conservator, commonly known as the oil pillow, is a cylindrical container placed horizontally above the oil tank and connected to the transformer oil tank by a pipe. When the transformer oil expands due to heat, the oil flows from the oil tank to the oil conservator; when the transformer oil contracts due to cold, the oil flows from the oil conservator to the oil tank. Therefore, the transformer oil conservator device is an important transformer component. Among the existing transformer oil conservator devices, there is no transformer oil conservator device based on external oil. The corrugated expansion tube is still placed horizontally, and the corrugated expansion tube is filled with high-pressure gas. The corrugated expansion tube occupies the transformer oil storage space, and generates an outward flow force on the transformer oil. Since the corrugated expansion tube occupies the transformer oil storage space, the storage capacity rate of the oil conservator device for the transformer oil is affected.

[0003] The utility model uses the technical feature of the contraction body in the initial state as the force for the transformer oil to flow outward, and effectively explores and studies the technical problem of placing the corrugated expansion tube horizontally and then filling the corrugated expansion tube with high-pressure gas at the technical level.

[0074] A supporting connection point for the casing 1 is formed by the gas sensor 95, and the connection with the casing 1 is realized by the gas sensor 95. The technical purpose of the gas sensor 95 is to be used as a component for detecting the amount of air contained in the transformer oil.

[0075] In this embodiment, the center line of the box shell 1, the center line of the liquid outlet pipe 4, the center line of the load-bearing plate 5, the center line of the middle through pipe 96, the center line of the cover box 93 and the center line of the coil 94 are arranged on the same straight line.

[0076] The method of using this embodiment is as follows: connect the valve port of the liquid outlet pipe 4 to the oil port of the transformer, connect the output oil port of the main transformer synchronous vacuum oil injection machine to the valve port of the liquid inlet pipe 3, connect the vacuum port of the main transformer synchronous vacuum oil injection machine to the valve port of the coil 94, loosen the plugging bolt on the intermediate through pipe 96, close the valve of the liquid outlet pipe 4, open the valve of the liquid inlet pipe 3 and the valve of the coil 94, put the main transformer synchronous vacuum oil injection machine in working state, inject the transformer oil into the box part 11 through the liquid inlet pipe 3, vacuum the first bellows 6 through the coil 94 and the first through pipe 9, vacuum the second bellows 7 through the coil 94 and the second through pipe 92, put the first bellows 6 and the second bellows 7 in a contracted state, discharge the gas in the box part 11 through the intermediate through pipe 96, when the transformer oil in the box part 11 When it is full, the excess transformer oil overflows through the intermediate through pipe 96, so that the plugging bolt on the intermediate through pipe 96 is in a tightened state, the valve of the liquid inlet pipe 3 and the valve of the coil 94 are in a closed state, the main transformer synchronous vacuum oil injection machine is in a non-working state, the output oil port of the main transformer synchronous vacuum oil injection machine is separated from the valve port of the liquid inlet pipe 3, the vacuum port of the main transformer synchronous vacuum oil injection machine is separated from the valve port of the coil 94, the valve of the liquid outlet pipe 4 is in an open state, the oil port of the transformer is in a connected state with the box part 11, and the transformer oil is injected into the transformer.
