Embodiment Construction

[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0020] In the embodiment, the insulating porcelain sleeve is prepared according to the following process steps:

[0021] First, adjust the insulating porcelain mud, add the mud to the ball mill for 3 hours, pass the milled mud through a 200-mesh sieve, and take the sieved mud to perform strong magnetic iron removal, chemical iron removal, and electrolytic iron removal in sequence The three-stage iron and iron removal operation is adopted, and the mud after iron removal is dried for later use. On the other hand, the unsaturated polyester resin is formulated into a solution with a concentration of 5%, and the sieved mud and unsaturated polyester resin solution are added to the mixing tank to prepare a suspension mixed slurry with a solid phase volum...

Abstract

A continuous production process of 500KV insulating insulator comprises: selecting an insulating petuntse, unsaturated polyester resin and other auxiliaries for mixing to preparing suspensoid mixed slurry, pugging the unsaturated polyester resin to prepare a blank, performing ageing, secondary pugging and electric drying in the shade on the prepared blank, fettling the blank after the electric drying in the shade and performing ten-section heating calcinating, performing six-section cooling calcinating after the ten-section heating calcinating, standing the calcinated blank at room temperature for 3-5 days, performing finishing, trimming and surface processing to prepare the product. The insulating insulator prepared by the continuous production process is reasonable in structure, convenient to load and unload and high in environmental interference resistance, and stably works under 500KV ultrahigh voltage environment.

Description

technical field [0001] The invention belongs to the technical field of production of insulating porcelain bushings, in particular to a continuous production process of a set of 500KV class insulating porcelain bushings. Background technique [0002] The existing 500kV level high-voltage insulating porcelain bushings generally refer to the design and process experience of capacitive bushings, but this design and process experience have certain limitations in the preparation of high-voltage insulating porcelain bushings, and there are technical requirements. High cost, high cost, low technical and economic efficiency of the bushing, etc. At the same time, it is very difficult to operate when assembling and using. Once the bushing is improperly assembled, it will cause the breakdown of the bushing electrode and give high voltage The safe and stable operation of the casing brings great hidden dangers. [0003] However, with the continuous development of motor insulation technol...
