Problems solved by technology

However, the post composite insulator with solid structure is heavy, which is not conducive to transportation and installation
[0003] For this reason, some technicians have proposed hollow post insulators, but pure hollow post insulators need to be strengthened in terms of mechanical strength and overall sealing performance
In addition, general air-filled insulators need to add a drying device to improve the degree of internal drying, but the current common drying device is a metal sieve structure, which reduces the internal insulation distance and costs more

Embodiment Construction

[0018] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0019] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to t...

Abstract

The present application discloses a hollow post insulator, including a hollow insulating tube, sheds covering and fixed to the outer circumferential surface of the hollow insulating tube, and flangessleeving both ends of the hollow insulating tube. Each flange includes a flange plate and a flange cylinder. The inner walls of the two ends of the hollow insulating tube are tapered. An end sealing structure is disposed in the hollow insulating tube. The end sealing structure seals and connects the hollow insulating tube and the flanges. The height of the end sealing structure is greater than that of the flange cylinders sleeving the outer side of the hollow insulating tube. The hollow post insulator uses the hollow insulating tube with two tapered ends, and is sealed in combination with theend sealing structure to enhance a sealing effect. An automatic sealing device is disposed on one end of the hollow insulating tube so as to facilitate inflating and deflating operations. A receivingpart is also arranged in the end sealing structure for containing a desiccant, thereby ensuring that the micro-water content in the insulating tube is kept below a standard value, and ensuring the internal insulation effect of the insulator.

Description

technical field [0001] The invention relates to equipment for power transmission and transformation in the electric power industry, in particular to a hollow post insulator. Background technique [0002] At present, composite insulators are mainly divided into two categories, one is hollow composite insulators, and the other is post composite insulators. Conventional post composite insulators are of solid structure. However, post composite insulators with a solid structure are heavy, which is not conducive to transportation and installation. [0003] For this reason, some technicians have proposed hollow post insulators, but purely hollow post insulators need to be strengthened in terms of mechanical strength and overall sealing performance. In addition, general air-filled insulators need to add a drying device to improve the degree of internal drying, but the current common drying device is a metal sieve structure, which reduces the internal insulation distance and costs m...
