Embodiment Construction

[0011] specific implementation plan

[0012] Crumble the pulp plate (1) into pulp (2) concentrate (3) put it into the pulp tank (4), and disc refiner (5) grind the pulp to a degree of knocking of 34±1°SR and a wet weight of 14±1g to the pulp tank (6), use the pump (7) to dilute the ground slurry to a concentration of 0.3 ± 0.05%, and then go to the centrifugal distributor (9) after the low-concentration slag remover (8) removes the slag, and the centrifugal distributor removes the slurry Distribute in the mold (11) that adjusts dividing plate size, mold bottom plate, dividing plate and inner wall all lining good 40-50 mesh nylon mesh (10). When the amount of material displayed by the flowmeter (12) on the centrifugal distributor reaches the requirement, the slurry pump stops automatically. When the centrifugal distributor works, the vacuum pump (13) starts to vacuumize. When the slurry pump stops, the vacuum pump continues to vacuumize for 10-15 minutes and then stops. Cover ...

Abstract

The invention relates to a process for producing an insulating rectangular stay of a transformer, belonging to the processing field of paper-making process and the insulating rectangular stay of the transformer. The invention aims to provide a process for producing the insulating rectangular stay of the transformer through one-step molding. A finished product is prepared through processes of breaking, concentration, pulping, deslagging, mold-pressing formation, hot-pressing and the like. An insulating member subjected to one-step molding reduces the processing procedures and saves energy sources. Without adhesives, a rectangular stay subjected to the one-step molding improves the electric insulation performance and is suitable for a high-voltage transformer; and because of high fiber purity degree, the rectangular stay subjected to the one-step molding has less loss than a laminated rectangular stay medium, and the quality security guarantee coefficient of the transformer can be improved.

Description

technical field [0001] The invention relates to a production process for transformer insulating rectangular stays, and belongs to the fields of papermaking technology and processing of transformer insulating rectangular stays. Background technique [0002] Transformer insulating rectangular stays are mainly used as insulating parts. At present, transformer insulating rectangular stays are made of insulating cardboard through cutting, bonding, drying and mechanical processing. The purity of the parts affects the withstand voltage performance of the transformer. Contents of the invention [0003] The purpose of the invention is to provide a production process for one-time forming transformer insulating rectangular stays. [0004] The realization process of the present invention is as follows: [0005] Disintegrate and concentrate the high-chemical pure electrical grade pulp board, and beat it with a disc refiner to meet the process requirements. The pulping angle is 34±1°...
