Abstract

The utility model discloses a novel high voltage whole operating mode DMC bus post insulator, which is made of DMC material. An aluminum flange used for installing and fixing the insulator is once hot-pressed and molded at the bottom of the insulator; a round hole used for damping and propping tightly is arranged at the top of the insulator; and an anti-fouling umbrella shape skirt with intervals is arranged on the surface of the insulator. In order to make the aluminum flange at the bottom of the insulator combined more firmly with the insulator, the utility model adopts the once hot-press molding technology to combine the aluminum flange and the insulator. The utility model has the advantages that the mechanical strength of the utility model is more two times as much as a porcelain insulator; the utility model never conducts magnetism; the utility model is uneasy to fall off, not resulting in the bursting of the insulator; the creepage distance is long, being anti-fouling; the utility model is hydrophobic, and the hydrophobic mobility is good; the utility model is track resistant, being never struck, not absorbing the moisture; and the dew congealing insulating performance is high, which is more hundredfold as high as the porcelain insulator (kV / M Omega is calculated according to the national lowest power transmission standard).

Description

The full operating mode DMC bus of novel high-pressure supporting insulator

Technical field

The utility model relates to a kind of insulator, and specifically, the utility model relates to a kind of full operating mode bus of high pressure supporting insulator of being made by DMC (unsaturated polyester glass fibre reinforced mould plastic) material.The full operating mode DMC bus of this high pressure supporting insulator can be applicable to 10-35KV case enclosed busbar altogether.

Background technology

At present, mostly the common bus-bar insulator of people is porcelain, is inlaid with the fixture of an irony in the bottom of insulator, is used for insulator is fixed in the enclosed busbar shell.The shortcoming of this porcelain insulator is: 1, bad mechanical strength, frangible; 2, owing to be embedded in the fixture of porcelain insulator bottom and made by no-magnetic casting iron, easy magnetic conduction easily comes off, creep distance is little, not antifouling, also causes the porcelain insulator spalling easily; 3, do not have hydrophobic, migration of hydrophobicity is poor; 4, the electric trace of tolerance is poor, can not use after the puncture again; 5, easily the moisture absorption, condensation insulation effect are poor.

Summary of the invention

In view of the foregoing, the purpose of this utility model provides a kind of full operating mode bus of high pressure supporting insulator of being made by the DMC material.

For achieving the above object, the utility model adopts following design: the full operating mode DMC bus of a kind of high pressure supporting insulator, and it is made by the DMC material; The once hot-forming ring flange that is used to install and fix insulator that an aluminium matter is arranged in the bottom of insulator; There is one to be used for the circular hole that damping holds out against at the top of insulator.

For the aluminium matter ring flange that makes insulator bottom combine with insulator more firm, the utility model aluminium matter ring flange and hot-forming forming of mould of insulator employing.

The utility model has the advantages that: mechanical strength is more than 2 times of porcelain insulator; Magnetic conduction never; Difficult drop-off can not cause the insulator spalling; Creep distance is big, antifouling; Hydrophobic, migration of hydrophobicity is good; Tolerate electric trace, never puncture; Nonhygroscopic, condensation insulating properties height is that porcelain insulator is more than hundred times (by the minimum electric standard calculating K V/M Ω that send of country).

Description of drawings

Fig. 1 is the utility model structural representation.

Embodiment

As shown in Figure 1, the full operating mode DMC bus of the disclosed high pressure of the utility model supporting insulator 1 is to be made by the DMC material.The once hot-forming ring flange 2 that is used to install and fix insulator that an aluminium matter is arranged in the bottom of insulator 1.

Be provided with the antifouling full skirt 3 of size interval on the surface of insulator 1.There is one to be used for the circular hole 4 that damping holds out against at the top of insulator 1.

For the aluminium matter ring flange 2 that makes insulator bottom combine with insulator 1 more firm, as shown in the figure, hot-forming forming of mould of described aluminium matter ring flange 2 and insulator employing.

The utility model has the advantages that: 1, the mechanical strength height is more than 2 times of porcelain insulator; 2, because insulator bottom is once hot-forming an aluminium matter ring flange is arranged, so magnetic conduction never; Difficult drop-off can not cause the insulator spalling; 3, because insulator surface is provided with the antifouling full skirt of size interval, so creep distance is big, antifouling; 4, hydrophobic, migration of hydrophobicity is good; 5, tolerate electric trace, never puncture, nonhygroscopic, condensation insulating properties height is that porcelain insulator is more than hundred times (by the minimum electric standard calculating K V/M Ω that send of country).

The above is specific embodiment of the utility model and the know-why used, and is any based on the equivalent transformation on the technical solutions of the utility model basis, all belongs within the utility model protection range.
