Abstract

The invention discloses an oil filter pipe connector for a transformer and relates to the technical field of pipe connecting devices. The connector comprises a male connector and a female connector, wherein the male connector comprises a first connecting tube, and a sealing ring is fixed at the end of the outer wall of the first connecting tube; the female connector comprises a second connecting tube provided with two openings, two pairs of connecting plates are arranged on the pipe walls outside the openings, two locking rods are respectively in shaft connection with one pair of connecting plates, one ends of the locking rods are located in the openings of the second connecting tube, the other ends of the locking rods are located outside the second connecting tube, an annular groove is formed in the inner wall, on the right of the openings, of the second connecting tube, a sealing rubber ring is fixed in the annular groove, and the inner diameter of the sealing rubber ring is slightly larger than the outer diameter of the sealing ring. By the oil filter pipe connector, two oil filter pipes can be connected conveniently and fast, a good sealed connection effect is achieved, and transformer oil leakage is avoided.

Description

technical field

[0001] The invention relates to the technical field of pipe connection devices, in particular to an oil filter pipe joint of a transformer. Background technique

[0002] Unless regular maintenance is performed, transformer oil can become contaminated no matter how carefully the transformer is installed and operated. As soon as the insulating properties of the oil decrease, equipment failure occurs. The cost of equipment failure is much greater than the cost and time spent on proper transformer oil maintenance. The purpose of transformer oil treatment is to remove moisture and other contaminants from the oil that has been in use or will be used in the equipment. In the process of oil filtering for transformers, it often happens that the oil filter unit is too far away from the oil storage point, and the oil filtering pipelines are not long enough, and the oil filtering pipelines cannot be connected together, so that The oiling process is difficult. Even if ...
