Description
Technical field
The present invention relates to capacitor area, it is applied to 800kV chopper shnt capacitor particularly to one kind.
Background technology
Constantly improve with China's power system technology, Ge great High-Voltage Electrical Appliances manufacturing company research and development strength constantly strengthens, high
Press switch structure is more reasonable, performance is relatively reliable, and China has had enough strength to carry out supertension and extra-high voltage high-tension electricity
The research and development of device and production；And, strengthen with national economic strength, the continuous reality of great national construction project and development of the West Regions
Apply, the demand of high-tension switch gear is also increasingly increased, electric pressure is progressively gone forward one by one to 800kV from 330kV, 550kV, northwest electricity
Net also carried out technology and economy comparison to 550kV and two schemes of 800kV, result show 800kV gross investment and annual cost all than
550kV significantly reduces, and 800kV voltage conveying electricity improves power transmission distance and transmission capacity, decreases transmission losses,
In high-tension switch gear, with chopper as representative, its arc quenching principle, it is related to aerodynamicss, machine driving, High-Voltage Insulation etc.
Multi-disciplinary knowledge.Chopper, with arc-chutes as core component, in primary cut-out, only contains arc-chutes, referred to as single disconnected
Mouth chopper；Containing two arc-chutes, referred to as double-fracture chopper, primary cut-out is to improve its break performance, particularly opens
The ability of disconnected close-in fault, often shnt capacitor between fracture, when shnt capacitor is installed between the fracture of double-fracture, also act as
The effect of fracture all pressures, therefore, shnt capacitor plays very important effect in high-voltage switch gear.
At present, the shnt capacitor that high-voltage switch gear is adopted, by external import, is rolled using overall, is subsequently adding electrolysis
Matter, compacting forms, and it is larger that such condenser capacity can be done, but single volume is larger, and in terms of bearing overvoltage
Poor, application is also dumb.Have impact on circuit breaker design, its reliability of operation there is also certain query, due to capacitor
Unique industry characteristics, domestic manufacturer do not possess the ability of manufacturing country external capacitive body at present.Therefore, current the surpassing of China
The capacitor that primary cut-out uses can only result in chopper production cost height from external import, and delivery cycle is long, and occurs
Problem is difficult to solve, and have impact on the delivery cycle of domestic production producer.
Content of the invention
The present invention is in order to make up prior art defect, there is provided a kind of structure is simple, and the 800kV chopper of convenient use is used
Parallel capacitor.
The present invention is achieved through the following technical solutions：
A kind of 800kv chopper shnt capacitor, including fixed plate, capacitor assembling and fixed seat, described fixed plate
Two ends are respectively provided with capacitor assembling, and capacitor assembling is connected by bolt and pad with fixed plate, two capacitor assembly ends
Connected by fixed plate, capacitor assembly end is connected with pad by nut with fixed plate, described fixed plate central shaft both sides
Symmetrical equipped with fixed seat, described capacitor assemble outside the fixed plate at two ends symmetrical equipped with fixed seat, in described fixed seat equipped with
Two fixing holes, equipped with insulating cylinder outside the assembling of described capacitor, capacitor assembles one end equipped with joint one, other end equipped with
Joint two, capacitor assembles built with capacitor, in described capacitor assembling between the capacitor and joint two of joint two
Equipped with spring, equipped with shielding gasket between spring and capacitor.
The invention has the beneficial effects as follows：Structure is simple, and easy to use, safe and reliable, having broken away from product is affected by import partses
Constraint, change that import capacitor is non-adjustable and expensive, the problem of delivery cycle length, by using self-control insulation tube
And capacitor, and series-parallel special construction so that shnt capacitor dielectric level between fracture and capacity all changes adjustable,
Facilitate design and installation, all pressures performance improved between fracture and improve break performance and all greatly improve and cheap,
Be conducive to promoting.
