Problems solved by technology

However, because it only changes the electrical properties of the product surface, but does not solve the problem of relatively low internal insulation of the product, it is still necessary to detect the "zero" value. The design of the silicone rubber shed shed is relatively thin, and the wind pressure resistance is low. Not suitable for use in some areas
[0006] At present, the adhesive used in composite insulators has high mechanical strength and strong bonding function, but it has no semi-conductive properties, and cannot eliminate partial discharge well, which will cause the internal temperature of the insulator to be too high and damage the product, resulting in unnecessary power supply accidents

Abstract

The invention discloses a plate-shaped suspension type bi-insulation composite insulator and a formula of medium electric adhesive; wherein the plate-shaped suspension type bi-insulation composite insulator comprises a metal upper connecting piece, an insulator and a metal lower connecting piece; the metal upper connecting piece and the insulator are adhered with adhesive, and an insulation rod is arranged between the metal lower connecting piece and the insulator. The medium electric adhesive comprises the following components by parts by weight: 20-50 parts of epoxy resin, 20-40 parts of cement, 5-20 parts of conductive powder and 10-20 parts of organic solvent. The invention has the advantages that product inner insulation strength is greatly improved and various accidents formed by glass insulation breakage caused by rapid change of temperature are eliminated. Meanwhile the invention also provides a medium electric adhesive with high strength and bonding property, the medium electric adhesive has semiconductive function, thus discharge and leakage in all manners in the interior of the product can be avoided and the medium electric adhesive also can be used in occasion of otherhigh voltage electrical apparatus requiring shielding.

Description

Technical field: [0001] The invention relates to an insulator used in a high-voltage power transformation line and an adhesive for the insulator, in particular to a disk-type suspension double-insulation composite insulator and an intermediate dielectric adhesive for the insulator. Background technique: [0002] Insulators are an indispensable part of high-voltage power transmission and transformation lines, and are closely related to the development of the power industry. There are mainly three types of porcelain insulators, tempered glass insulators and silicone rubber composite insulators currently used in the market. [0003] Porcelain insulators are traditional products still used in our country. The main insulation is porcelain, which has been used for many years. At present, there are still a large number of operations in high-voltage transmission lines; tempered glass insulators are insulators for high-voltage lines, and the main insulation is tempered glass.
