Abstract
The invention relates to a capacitor of anti-fouling type breaker, comprising a sleeve, an upper end cover, a lower end cover, a bellows piece and an expander; the sleeve is a high-intensity high-voltage electric porcelain sleeve shell, the upper and lower ends of the sleeve are provided with aluminium alloy end covers and flanges, and the internal dielectric material of the sleeve is a full oil-immersed film, and a plurality of elements which adopt polypropylene film as medium are completely connected in series; an oil sealing screw is arranged at the connecting position of each end cover anda pipe section, and impregnant made of alkylbenzene is arranged between the end cover and the expander. The capacitor has the beneficial effects that: the manufacturing cost is low, the capacitor hasgood performance and wide expandable space; creep age distance, mechanical intensity and overall dimension and weight are all considered, and rational structure can lead electric field nearby the electrode to be uniform; the electric strength can completely achieve the requirements, the withstand voltage level and local discharging level are improved, and the loss value is reduced; the local discharging level and the reliability of a product can be improved.
Description
Technical field
The present invention relates to superhigh pressure AC input transformation system field, specifically a kind of capacitor of anti-fouling type breaker.
Background technology
The capacitor external insulation problem of existing circuit breaker has become a key issue in the development.Because the product height can't increase, and the numerical value of power frequency, lightning impulse, switching impulse withstand voltage all is higher than the numerical value of national standard and present similar products at home and abroad, therefore has higher difficulty in this respect, its solution must be taken into account the contradiction of creepage distance, mechanical strength and overall dimension and weight, main feature has: electrode shape is approximately spherical, the burr on surface is done strict the processing, makes that near the electric field the electrode is more even; Each size of the umbrella shape of porcelain bushing, umbrella distance and big umbellule is chosen relatively rationally through prudent calculating, and enough creep distances and bigger wet flashover distance can be arranged under highly constant condition, and electric strength has reached requirement fully.In addition, the selection of the work field intensity of interior insulated part also is a major issue, can select with full film is medium, and its work field intensity can be higher than complex media; The element connected in series number is more, and element voltage is relatively low; The improvement of cleanliness factor and saturating machine has improved withstand voltage level and local discharging level, has reduced loss value; Rationally selecting for use of expander makes product inside when low temperature negative pressure and air gap can not occur, can improve local discharging level and product reliability.
Summary of the invention
At above defective, the capacitor of anti-fouling type breaker that the purpose of this invention is to provide a kind of cheap, stable performance, low-loss, has good electric strength is to solve many defectives of existing like product.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of capacitor of anti-fouling type breaker, comprise sleeve pipe, two end cap up and down, described sleeve pipe is a high strength high tension insulator sleeve shell, its upper/lower terminal is equipped with Aluminum Alloy Cover and flange, described bellows piece is arranged at the fuse two ends, and described inside pipe casing dielectric material is that full film of oil immersion and the multicomponent that adopts polypropylene film to make medium are connected entirely; The joining place of each end cap and pipeline section is provided with the oil sealing screw, and sealing ring is settled in the outside of this oil sealing screw; Described ripple tube stay tube and expander are arranged at end cap the inner, are provided with the impregnating agent that gastral cavity base benzene is made between described end cap and the expander.
The beneficial effect of capacitor of anti-fouling type breaker of the present invention is: cheap, have good performance, have wide expanding space; Can take into account creepage distance, mechanical strength and overall dimension and weight, its setting rational in infrastructure can make that near the electric field the electrode is more even; Electric strength has reached requirement fully, has improved withstand voltage level and local discharging level, has reduced loss value; Can improve local discharging level and product reliability.
