Abstract

A kind of novel basin-shaped insulator to be dissipated based on charge regulation and control and active, including insulation resistance area and electric-charge-dissipating area, electric-charge-dissipating area surface are coated with anti-static coating.Advantage is:By the shape for changing existing insulator, charge is set to accumulate in the side wall of electric charge gathering region under DC electric field effect, anti-static coating is coated by side wall, make the reduction of sidewall surfaces resistivity, the charge for being adsorbed on sidewall surfaces can be made to be easier to dissipate in this way, to play the purpose of charge active control and dissipation.

Description

Based on charge regulation and control and the novel basin-shaped insulator actively to dissipate
Technical field
The present invention relates to equipment for power transmission and distribution technical field, especially a kind of New type basin to be dissipated based on charge regulation and control and active Formula insulator.
Background technology
Gas-insulated metal closed power transmission line (GIL) is big with transmission capacity, it is friendly that small, safe and environment is lost Well equal various features are the effective means transmitted for the electric energy of large capacity, long range.Transmission of electricity corridor is intensive, strategically located and difficult of access landforms, Under the particular surroundings such as rivers,lakes and seas, gas-insulated metal-enclosed circuit then becomes being preferably selected for electrical energy transportation.Currently, gas is exhausted Although edge metal closed power transmission line has worldwide gradually been used widely, however, main application is in exchange In power grid, and the application of GIL is rarely reported in DC transmission system.In recent years, there are many manufacturers in the world, such as Mitsubishi, Toshiba, Germany's electric power esbablished corporation such as Siemens and Switzerland ABB have all been carried out around direct current GIL and have been ground in succession Work is sent out, but is showed no formal commercial operation report, main reason is that long-term work is under high voltage direct current environment, GIL Disc insulator surface in equipment has the accumulation of charge, this original electric field that will distort causes insulating part flashover voltage notable It reduces.Currently, with the fast development of China's high voltage direct current transmission project, the demand to direct current GIL equipment is increasingly urgent to, in The research of surface charge accumulation characteristic and control measure of portion's insulating part under high voltage direct current has become various countries electric power research personnel One of hot issue of research.
In recent years, for the research of disc insulator surface charge accumulation problem in direct current GIL, it is exhausted to be concentrated mainly on gas-solid The measure theory and accurate measuring technique of edge barrier surface charge, D.C. isolation part surface charge accumulation characteristic and dissipation characteristic, Surface charge control measure etc..However, so far, most of correlative study remains in simulation analysis and lab scale The study on the modification of product sample block, the correlative study of the novel high-pressure direct current GIL disc insulators with commercial Application potential is still It is rarely reported.
In addition, the insulator of existing design, top climbs that electric spacing is too low, and using effect is bad.
Invention content
The purpose of the present invention is to solve the above problem, devises and a kind of dissipate based on charge regulation and control and actively novel Disc insulator.Specifically design scheme is:
A kind of novel basin-shaped insulator to be dissipated based on charge regulation and control and active, including insulator matrix 1 and electric-charge-dissipating Area 2, the insulator matrix 1 act as isolation high-pressure conductor and grounding electrode, play the role of insulation, the electric-charge-dissipating Area 2, surface be coated with anti-static coatings, the insulator matrix 1 include epoxy resin, aluminium oxide, surface be solidification after Epoxide resin material;
The anti-static coatings are the fat-soluble antistatic agent of epoxy resin;
The coating method of the anti-static coatings is by the coating according to mass ratio 1:30~1:50 proportioning and alcohol are mutual Melt, is then uniformly applied to the insulator electric-charge-dissipating area poured and be poured in, dries.
The insulator matrix 1 is the overall structure that vacuum mixes moulding by casting.
The vertical cross-section of the insulator matrix 1 is in bowl structure, and 2 surface of electric-charge-dissipating area is applied coated with antistatic Material.
When the dilution of 2 surface anti-static coating of the electric-charge-dissipating area is 30 times, resistivity declines 3 orders of magnitude.
