Problems solved by technology

[0006] Aiming at the problems existing in the prior art, the object of the present invention is to provide a floating oil-immersed transformer with superimposed oil pipes. Through the arrangement of superimposed oil pipes, when the transformer oil is blocked due to air pressure in the superimposed oil pipes, The floating ball rises with the blocked transformer oil level, and then approaches the moving sinking ball. Due to the mutual repulsion between the moving floating ball and the moving sinking ball, the moving floating ball and multiple moving sinking balls move, causing the transformer oil to turbulent. In turn, the balance of the air pressure is destroyed, so that the clogged transformer oil seeps down quickly, effectively avoiding the clogging at the superimposed section. Compared with the existing technology, it significantly reduces the occurrence of transformer oil leakage, and improves In addition, when the transformer oil fails to seep under the turbulence, you can manually shake the straight section to make a strong turbulence at the superimposed section, and accelerate the seepage of the transformer oil

Embodiment 1

[0044] see Figure 1-2 , a floating oil-immersed transformer with laminated oil pipes, including a transformer body 1, an oil tank is arranged inside the transformer body 1, a laminated oil pipe 2 is installed on the upper end of the transformer body 1, and the laminated oil pipe 2 communicates with the oil tank.

[0045] see Figure 2-3 The laminated oil pipe 2 includes a straight section 21 and a laminated section 22 fixedly embedded in the straight section 21. The laminated section 22 is located at a position below the center line of the laminated oil pipe 2. The straight section 21 is of a hard structure. Combined section 22 is a folded corrugated structure, please refer to Figure 5 , when replenishing transformer oil, the straight section 21 can be pulled upwards to extend the stacked section 22, thereby effectively extending the overall length of the stacked oil pipe 2, so that when the transformer oil is clogged under the action of air pressure, the path to overflow i...

Embodiment 2

[0049] see Figure 8 The moving buoy 6 includes an outer sealing balloon 81 and an inner weight-reducing layer 82 located in the outer sealing balloon 81, the space between the outer sealing balloon 81 and the inner weight-reducing layer 82 is saturated with air, and the upper end of the inner weight-reducing layer 82 The magnetic piece 63 is fixedly embedded, and the outer end of the magnetic piece 63 extends to the surface of the outer sealing balloon 81. The inner weight-reducing layer 82 is made of the same material as the outer weight-reducing layer 61, and the surface of the inner weight-reducing layer 82 is sealed by wrapping a sealing film. Make it difficult for air to penetrate into the inner weight-reducing layer 82, thereby effectively ensuring the relatively full shape of the outer sealing balloon 81, making it difficult to reduce the volume due to air entering the inner weight-reducing layer 82, thereby effectively ensuring that it can be used with the transformer ...

Abstract

The invention discloses a floating type oil-immersed transformer with an overlapped oil pipe, and belongs to the field of transformers. According to the floating type oil-immersed transformer with an overlapped oil pipe, through the arrangement of the overlapped oil pipe, when transformer oil blockage occurs in the overlapped oil pipe due to air pressure, a movable floating ball ascends along with the oil level of the blocked transformer oil and then gets close to a movable sinking ball; due to mutual repulsive force between the movable floating ball and the movable sinking balls, the movable floating ball and the movable sinking balls move, transformer oil vibrates, then air pressure balance at the position is damaged, blocked transformer oil rapidly permeates downwards, the situation that the transformer oil is blocked at the overlapping section is effectively avoided, compared with the prior art, the situation that the transformer oil permeates outwards is remarkably reduced, and the oil supplementing efficiency is improved. In addition, when the transformer oil does not permeate downwards under shaking, the straight section can be manually shaken to enable the overlapped section to generate shaking with large intensity, and the transformer oil permeation is accelerated.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a floating oil-immersed transformer with laminated oil pipes. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage.
