Embodiment 1

[0017] Such as figure 1 As shown, the separation mechanism for the gas in the transformer insulating oil includes an upper separation shell 1, a lower separation shell 2 and an oil-gas filter barrel 3, wherein the upper separation shell 1 forms a cylinder with an open lower end, and the lower separation shell 2 forms a cylinder with an open upper end. Cylinder-shaped, the upper end of the lower separation shell 2 is sealed and connected with the lower end of the upper separation shell 1, and the oil and gas filter barrel 3 is arranged in the lower separation shell 2, and its upper end is sealed and connected with the inner wall of the lower separation shell 2. A gas cavity is formed between the upper separation shell 1, the lower separation shell 2, and the oil-gas filter barrel 3, and an oil-liquid transition chamber is formed between the lower separation shell 2 and the oil-gas filter barrel 3. The sides of the upper and lower ends of the lower separation shell 2 An oil outl...

Embodiment 2

[0020] This embodiment makes the following further limitations on the basis of Embodiment 1: the oil and gas filter barrel 3 of the present embodiment includes a metal shell and a polymer ceramic membrane arranged on the inner wall of the metal shell, wherein the metal shell of the oil and gas filter barrel 3 It is in the shape of a barrel with an open upper end, and the side wall of the metal shell is formed with uniformly distributed pores. In this embodiment, the diameter of the pores on the metal shell is 12-18 microns.

Embodiment 3

[0022] In order to facilitate the connection of the lower separation shell 2 with the upper separation shell 1 and the oil and gas filter barrel 3, this embodiment makes the following further limitations on the basis of embodiment 1 or embodiment 2: the metal of the oil and gas filter barrel 3 of this embodiment The upper end of the casing protrudes outwards to form an annular connection platform, on which an annular connecting piece is arranged, and a second annular gasket 13 is arranged between the lower separation shell 2 and the annular connecting piece, and the second annular sealing gasket 13 is connected to the lower separation casing. 2 is in close contact with the annular connecting piece, and the upper end of the oil and gas filter barrel 3 is connected to the lower separating shell 2 through a plurality of bolts that pass through the annular connecting piece, the second annular gasket 13 and are embedded in the lower separating shell 2. In this embodiment, the lower ...

Abstract

The invention discloses a separation mechanism for gas in insulating oil of a transformer, which comprises an upper separation shell, a lower separation shell and an oil-gas filter bucket, the upper end of the lower separation shell is connected with the lower end of the upper separation shell, and the oil-gas filter bucket is arranged in the lower separation shell, and its upper end is connected to the lower end of the upper separation shell. The inner side wall of the lower separation shell is connected, and an oil transition chamber is formed between the lower separation shell and the oil-gas filter barrel. The upper separation shell, the lower separation shell and the oil-gas filter barrel form a gas chamber. An oil inlet pipe and an oil discharge pipe connected to the oil transition chamber are provided, a shut-off valve is arranged on the oil discharge pipe, and an oil outlet pipe connected to the oil liquid transition chamber is arranged on the side wall of the upper end of the lower separation shell. The outer wall of the oil and gas filter barrel is wound with a helical piece, and the helical piece separates the oil transition chamber to form a helical passage connecting the oil inlet pipe and the oil discharge pipe. The present invention has a simple overall structure, is easy to implement, is convenient to operate when separating the gas in the insulating oil of the transformer, and has high separation efficiency, thereby improving the efficiency of detecting the gas in the insulating oil of the transformer.

Description

technical field [0001] The invention relates to the field of power transformer protection, in particular to a gas separation mechanism in transformer insulating oil. Background technique [0002] With the development of modern society, electric energy has become an indispensable energy in production and life. At the same time, people have put forward higher requirements for the safety of power grids. The power transformer is the key equipment of the power system, and its operation status is directly related to the safety and stability of the power system. Among them, the dissolved gas in the transformer insulating oil has a very close relationship with the internal fault of the transformer and the severity of the fault. Therefore, it is particularly important to detect the gas in the transformer insulating oil. When detecting the gas in the transformer insulating oil, it is often necessary to separate the gas in the transformer insulating oil. Nowadays, the equipment for se...
