Abstract

The invention discloses a production method of transformer bushing insulation paper through using a multi-cylinder fourdrinier machine. The method comprises the following steps: adding pure water to a wood pulp for size degradation, pulping, storing an obtained pulp, diluting the pulp, allowing the pulp to go through a stock discharge box to form a wet web on a screen, squeezing, drying, reeling, re-reeling, examining, packaging to form products, and warehousing. The transformer bushing insulation paper produced through adopting the method has the advantages of low conductivity, small medium loss, low tightness, good oil absorption property, moderate air permeability, large elongation, good strength, quantitative, uniform and stable water, consistent thickness, high output and low energy consumption.

Description

technical field [0001] The invention relates to a production method of insulating paper for transformer bushings, and belongs to the technical field of papermaking processing. Background technique [0002] Existing insulating paper for transformer bushings is generally produced by a rotary screen single-cylinder or double-cylinder paper machine. Firstly, the wood pulp is crushed, and then it is made by beating, papermaking, forming, pressing, drying, coiling and other processes. This production method has low output and high energy consumption; at the same time, due to the unreasonable use of pulp, water and technology, the electrical and physical properties of the product cannot meet the requirements of transformer bushing paper. Contents of the invention [0003] Purpose of the invention: Aiming at the problems and deficiencies in the prior art, the present invention provides a method for producing insulation paper for transformer bushings. [0004] Technical solution: ...
