Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] like Figure 1~3 , the transformer oil-soaked filter paper includes an outer filter bag 1, and the inside of the outer filter bag 1 is provided with a filter solid waste layer 2 and a water absorption layer 3, and the filter solid waste layer 2 is arranged above the water absorption layer 3. The solid waste layer 2 includes a debris layer 21, a transition layer 22, and a fine filter layer 23 from top to bottom. The pore size of the filter holes in the transition layer 22 is larger than the pore size of the filter holes in the fine filter layer 23 , and the debris layer 21 , the transition l...

Abstract

The invention relates to a transformer immersion oil filter paper. The transformer immersion oil filter paper comprises an outer filter bag, a solid waste filtering layer and a water absorbing layer are arranged in the outer filter bag, and the solid waste filtering layer is arranged above the water absorbing layer. The transformer immersion oil filter paper has a large filtering area, a low initial resistance, a high waste scrap capacity and a long service life. Solids in old transformer oil undergo three-stage filtration by a scrap accommodating layer, a transition layer and a fine filter layer, so solid impurities can be removed, the filtration efficiency is high, and the filtration effect is good; and water in the old transformer oil can be adsorbed by the water absorbing layer to complete dewatering work, and the filtering work and the dewatering work are simultaneously completed, so the operation is simplified, manpower and material resources are saved, and the implementing effect is good.

Description

technical field [0001] The invention relates to a transformer oil-soaked filter paper, which belongs to the technical field of transformers. Background technique [0002] Transformer immersion oil, referred to as transformer oil, is a fractionation product of petroleum. Its main components are compounds such as alkanes, naphthenic saturated hydrocarbons, and aromatic unsaturated hydrocarbons. It is commonly known as square shed oil. It is a light yellow transparent liquid with a relative density of 0.895. Transformer oil is a kind of mineral oil obtained through distillation and refining from natural petroleum. It is a pure and stable liquid natural hydrocarbon with low viscosity, good insulation and good cooling performance obtained by refining the lubricating oil fraction in petroleum with acid and alkali. Compound mixture. [0003] The main functions of transformer oil are 1) Insulation: Transformer oil has a much higher dielectric strength than air. The insulating mate...
