Description

A plate-type oil tank structure for oil-immersed transformers

technical field

The utility model relates to the technical field of transformer manufacturing, in particular to a plate-type oil tank structure for an oil-immersed transformer.

Background technique

The plate oil tank used in general oil-immersed transformers is equipped with an oil level gauge pressure relief valve on the tank cover. Its function is to detect the oil level of the transformer oil in the oil tank of the transformer and release the pressure in the oil tank when the gas is decomposed in the oil tank of the transformer and the air pressure increases.

The existing structure of the transformer plate oil tank mainly observes the oil level and releases the pressure through the pressure release valve of the oil level gauge. At present, because of the high purchase cost of the oil level gauge in this structure, the production cost rises and the profit margin decreases.

Utility model content

The purpose of the utility model is to overcome the defects of the prior art and provide a plate-type oil tank structure for oil-immersed transformers, which can directly observe oil samples, has simple structure design, convenient operation and relatively low cost.

The technical solution for achieving the above purpose is: a plate-type oil tank structure for oil-immersed transformers, including an oil tank body and a number of cooling fins installed on the side walls of the oil tank body, and the plate-type oil tank structure also includes at least one arc-shaped transparent Strengthened glass tube, each arc-shaped transparent strengthened glass tube is arranged vertically, each said arc-shaped transparent strengthened glass tube is located between two adjacent heat sinks, and each said arc-shaped transparent strengthened glass tube The two ends of the tube are connected to the flange welded on the side wall of the fuel tank body through the sealing ring one by one, and each arc-shaped transparent reinforced glass tube is also provided with an upwardly protruding pressure relief glass tube. The pressure relief glass tube and the corresponding arc-shaped transparent strengthened glass tube are interconnected and integrally formed. Two pressure relief holes are arranged on the upper part of the tube wall of each of the pressure relief glass tubes. Each of the pressure relief glass tubes A glass cap for covering the two pressure relief holes is arranged on the top.

In the above-mentioned plate type oil tank structure for an oil-immersed transformer, the two pressure relief holes are symmetrically arranged on the upper part of the tube wall of the corresponding pressure relief glass tube.

Compared with the prior art, the plate-type oil tank structure of the utility model for oil-immersed transformers has the beneficial effect of adding at least one transparent reinforced glass tube in the middle of the heat sink of the original plate-type oil tank to replace the original oil level gauge The function of the pressure release valve can directly observe the oil sample. This kind of structure is simple in design, easy to operate and relatively low in cost. Only need to add at least one arc-shaped transparent glass tube in the gap between the heat sink and the fuel tank body, it can play the role of the original pressure release valve of the oil level gauge, and because of the addition of these arc-shaped transparent glass tubes, there is Helps to improve the heat dissipation of the transformer.

Detailed ways

In order to enable those skilled in the art to better understand the technical solution of the present utility model, its specific implementation will be described in detail below in conjunction with the accompanying drawings:

Please refer to Fig. 1 and Fig. 2, the preferred embodiment of the present utility model, a kind of plate type oil tank structure that is used for oil-immersed transformer, comprises oil tank body 1, some cooling fins 2 that are installed on the side wall of oil tank body 1 and At least one arc-shaped transparent strengthened glass tube 3, each arc-shaped transparent strengthened glass tube 3 is vertically arranged, each arc-shaped transparent strengthened glass tube 3 is located between two adjacent heat sinks 2, and each arc-shaped The two ends of the transparent strengthened glass tube 3 are connected to the flange 5 welded on the side wall of the fuel tank body 1 through the sealing ring 4 correspondingly.

Referring to Fig. 3 to Fig. 5 again, an upwardly protruding pressure relief glass tube 6 is also arranged on each curved transparent strengthened glass tube 3, and the pressure relief glass tube 6 communicates with the corresponding curved transparent strengthened glass tube 3 and Formed integrally, each pressure relief glass tube 6 is provided with two pressure relief holes 61 on the upper part of the tube wall, and each pressure relief glass tube 61 is provided with a glass cap 62 for covering the two pressure relief holes 61 . The two pressure relief holes 61 are symmetrically arranged on the upper part of the tube wall of the corresponding pressure relief glass tube 6 .

In the plate-type oil tank structure of the utility model, the arc-shaped transparent glass tube 3 replaces the role of the crude oil level gauge pressure release valve and the oil sample valve. In normal use, the arc-shaped transparent glass tube 3 has transformer oil flowing through it, which is different from ordinary Heat sinks are no different. Due to the use of transparent materials, we can directly observe the condition of the transformer oil. According to the principle of equal internal and external pressure in physics, when the transformer oil in the oil tank decreases and the air pressure increases, the oil pressure in the curved transparent glass tube 3 will also decrease accordingly, and its oil level should be equal to the oil level in the oil tank. In this way, the oil level in the transformer oil tank can be easily observed. At the same time, when there is too much gas in the fuel tank and the pressure is too high, due to the principle of equal pressure inside and outside, the glass cap 62 on the pressure relief glass tube 6 will be pushed up, and the gas will flow from the two caps on the pressure relief glass tube 6. When the air pressure returns to normal, the glass cap 62 will fall, just to cover the two pressure relief holes 61 on the pressure relief glass tube 6, and the pressure relief is over.

Those of ordinary skill in the art should recognize that the above embodiments are only used to illustrate the utility model, rather than as a limitation to the utility model, as long as within the spirit of the utility model, the above-mentioned The changes and modifications of the embodiments will all fall within the scope of the claims of the present utility model.
