Description
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.

When the dilution of 2 anti-static coatings of electric-charge-dissipating area is 100 times, resistivity declines 1 order of magnitude.
The novel basin-shaped insulator to be dissipated based on charge regulation and control and active that above-mentioned technical proposal through the invention obtains,
Advantage is:
Make charge buildup in side wall by changing shape, side wall resistivity is low, can make to be adsorbed on sidewall surfaces in this way
Charge be easier dissipate, to play charge actively dissipate purpose.
