Problems solved by technology

[0002] The oil-immersed transformer is to install the winding and iron core in the oil tank filled with transformer oil. In order to prevent the oil level in the transformer from falling and prevent the winding and iron core from being exposed to the oil surface and cause inter-turn short circuit, it is necessary to add to the oil-immersed transformer. An oil conservator, the oil conservator plays the role of oil storage and oil replenishment, but when the oil-immersed transformer is installed outdoors, when it is raining and the outdoor air is relatively humid, the air in the oil conservator will increase with the volume of the transformer oil. When expanding or shrinking, the exhausted or inhaled air needs to pass through the respirator. The respirator is equipped with granular silica gel. However, as the silica gel absorbs moisture close to saturation, the moisture absorption effect of the respirator on the air in the oil pillow gradually decreases, resulting in dampness. The oil stored in the oil tank enters the oil tank, causing the oil in the oil tank to be damp, and it is easy to cause a short circuit in the shell of the oil-immersed transformer

Embodiment 1

[0024] as attached figure 1 to attach Image 6 Shown:

[0025] The invention is a lightning protection type transformer, the structure of which includes an oil tank shell 1, a radiator 2, a low-voltage bushing 3, a high-voltage bushing 4, a lightning rod 5, an oil pillow 6, and a dry breathing mechanism 7. Two ends of the oil tank shell 1 are provided with There is a radiator 2, the low-voltage bushing 3 is fixedly installed on the right end of the upper surface of the fuel tank shell 1, the high-voltage bushing 4 is fixedly installed on the left end of the upper surface of the fuel tank shell 1, and the lightning rod 5 is embedded in the middle end of the upper surface of the fuel tank shell 1 The oil conservator 6 is fixedly installed on the rear end of the fuel tank shell 1 and communicates with each other. The lower end of the oil conservator 6 is provided with a dry breathing mechanism 7 and communicates with each other. The dry breathing mechanism 7 includes an air inta...

Embodiment 2

[0033] as attached Figure 7 to attach Figure 8 Shown:

[0034] Wherein, the one-way discharge mechanism 744 includes a water collection chamber 44a, an opening and closing mechanism 44b, and a drain pipe 44c. The upper end of the water collection chamber 44a is fixedly installed on the lower end of the storage tank 741 and communicates with each other. There is an opening and closing mechanism 44b, and a drainage pipe 44c is arranged under the opening and closing mechanism 44b. The top of the drainage pipe 44c is fixedly installed at the lower end of the water collection chamber 44a and communicates with each other. The drainage pipe 44c has a structure with a wide inlet and a narrow outlet. It is beneficial to drain water and avoid backflow of water. There are two opening and closing mechanisms 44b in total, and they have a left-right symmetrical structure, which is good for water drainage and prevents external moisture from entering the water collection chamber 44a.

Abstract

The invention discloses a lightning protection type transformer. The transformer structurally comprises an oil tank shell, a radiator, a low-voltage sleeve, a high-voltage sleeve, a lightning rod, anoil conservator and a dry breathing mechanism, radiators are arranged at two ends of the oil tank shell, when in rainy days, the moisture of oil in the oil conservator is much, water in the oil is absorbed through granular silica gel placed on a partition plate in a storage tank, and heat generated in the working process of the transformer is radiated through the radiator. In the heat dissipationprocess, hot air enters through a hot air pipe, hot air enters the storage tank to dry the granular silica gel in order to prevent moisture absorption saturation of the granular silica gel, the absorbed water is discharged into a water collecting chamber through the storage tank, so that an opening and closing plate rotates around a rotating rod, the opening and closing plate is opened downwards,the water is discharged out of the water discharging pipe, the opening and closing plate is automatically reset through a torsion spring arranged on the rotating rod, external moisture is prevented from entering the storage tank, and oil in the oil tank shell is prevented from being affected with damp.
