Problems solved by technology

At present, the laminated cardboard used by transformers to make insulating structural parts is made of cardboard bonded and dried. This processing method cannot guarantee the uniformity and consistency of its insulating performance due to the adhesive contained in it.
The glue in the laminated cardboard affects the performance of the oil in the transformer and directly affects the withstand voltage performance of the transformer. Especially in the transformers with DC ±600 and above 1000kw, the adverse effect of the adhesive is very serious.

Embodiment Construction

[0007] With ultra-thick insulating cardboard, its water content is 4-7%, send into the semi-finished product room balance (15) and handle 3-5 days, cut into strips under the appropriate process speed, then the thick plate strips are rounded The forming tool is made into a circle, placed on a special combined lathe, and cut into a screw with an olecranon-shaped double-thin blade cutter at a speed of 3000-6000n / min. After passing the inspection, it is vacuum-packed and put into storage.

Abstract

The invention relates to a production process of an insulating paper screw, which comprises the following steps of: cutting an adhesive-free insulating cardboard into strips; then, processing the cardboard strips into circular shapes by using a special tool, placing the circular cardboard strips on a special combined lathe, and lathing into the screws under the rotating speed of 3000-6000 n / min by using a special shaped cutter; and removing cutting dust and edge burrs, and packaging into plastic bags in vacuum. The insulating paper screw produced by the process is applicable to extra-high tension transformers, and the electrical insulating property is improved.

Description

technical field [0001] The invention relates to an insulating paper production process, in particular to an insulating paper screw production process. Background technique [0002] The processing screw for pressing ultra-thick insulating cardboard is mainly used to replace laminated boards and used as insulating structural parts in key parts of transformers. At present, the laminated cardboard used by transformers to make insulating structural parts is made by bonding and drying cardboard. This processing method cannot guarantee the uniformity and consistency of its insulating performance due to the adhesive contained in it. The glue in the laminated cardboard affects the performance of the oil in the transformer and directly affects the withstand voltage performance of the transformer. Especially in the transformers above DC ±600 and 1000kw, the adverse effect of the adhesive is very serious. Contents of the invention [0003] The purpose of this invention is to use pure...
