Embodiment 1

[0045] This embodiment is a transformer vacuum oiling method, which can be used for both natural ester insulating oil oiling and mineral insulating oil oiling; it includes oil storage tank filtering oil filling process, transformer connection process, transformer oiling process and return Oil process; its specific process is as follows figure 1 shown.

[0046] The oil filtering and filling process of the oil storage tank refers to vacuum filtering the insulating oil and storing it in the vacuum oil storage tank;

[0047] The step of connecting the transformer means that the vacuum oil storage tank is connected to the transformer through an adapter; the connection between the transformer and the adapter and the pipeline between the adapter and the vacuum oil storage tank are vacuumed;

[0048] The transformer oil injection process refers to injecting insulating oil from the vacuum oil storage tank into the transformer;

[0049] The oil return process refers to returning the i...

Embodiment 2

[0063] The difference between the transformer vacuum oiling equipment in this embodiment and the first embodiment is that in this embodiment, double seals are used between the pipeline two 6 and the vacuum oil storage tank 2 and between the pipeline two 6 and the vacuum oil filter 4 Connectors realize the connection, such as image 3 with Figure 4 shown. The double-seal connection has good sealing performance, preventing air from infiltrating into the oil-filled environment from the connection. The double-seal connector includes a base 23, a plate body 25, a sealing layer 26, a sealing flange 27 and a nut 28; the base 23 is provided with a concave position; the plate body 25 is arranged in the concave position, There is a sealing ring 24 between them; the sealing layer 26 is arranged on the side of the plate body 25 away from the base 23, and the sealing layer 26 is located in the concave position against the side wall of the concave position; the sealing flange 27 and the ...

Embodiment 3

[0066] The difference between the transformer vacuum oiling method in this embodiment and the first embodiment is that in this embodiment, in the process of filtering and oiling the oil storage tank, vacuum filtering the insulating oil and storing it in the vacuum oil storage tank refers to: The original insulating oil in the transformer is extracted, and the oil is vacuum filtered through a vacuum oil filter, and then stored in a vacuum oil storage tank.

[0067] In order to realize the above transformer vacuum oiling method, this embodiment provides a transformer vacuum oiling equipment, the structure of which is as follows Figure 5 Shown; connector one 9 is connected with transformer 3, and the rest of the structure of this embodiment is the same as that of embodiment one. The original insulating oil can be discharged from the transformer as the source of insulating oil, and the original insulating oil of the transformer can be discharged, filtered, and reinjected to reali...

Abstract

The invention provides a vacuuming oiling method for a transformer, comprising: an oil filtering and oiling process of a storage tank, a connection process of the transformer, an oiling process of thetransformer, and an oil returning process, wherein the oil filtering and oiling process of the storage tank comprises vacuum filtering and storing the insulating oil in the vacuum storage tank; the connection process of the transformer comprises connecting the vacuum storage tank to the transformer through an adapter for vacuuming the pipeline; the oiling process of the transformer comprises injecting the insulating oil into the transformer from the vacuum storage tank; and the oil returning process comprises returning the insulating oil in the pipeline between the adapter and the vacuum storage tank to the vacuum storage tank. The method can remove impurities in the insulating oil, keep the oiling environment in an extremely high vacuum state, and insulate the air from the insulating oilto prevent the insulating oil from deteriorating. The invention also provides vacuuming oiling equipment for a transformer for realizing the vacuuming oiling method for the transformer.

Description

technical field [0001] The invention relates to the technical field of transformer oil injection, and more specifically, relates to a transformer vacuum oil injection method and equipment for realizing the method. Background technique [0002] Transformer insulating oil generally uses mineral insulating oil; however, with the increasing consumption of ore energy, traditional mineral insulating oil is facing an increasingly tight resource situation. And with the progress of society, the requirements for the installation environment of transformers are getting higher and higher, and the insulating oil of transformers needs to be non-toxic and non-polluting, so as to avoid pollution caused by transformer leakage. [0003] To meet these requirements, natural esters are currently used as insulating oils in transformers. Natural esters are insulating cooling fluids for distribution and power transformers. Natural esters can extend the life and performance of transformer insulatio...
