Abstract
The utility model discloses a self-cleaning capacitor, comprising a core group, an outer cover, lead terminals, fixing terminals, soakage material (liquid or gas) and sorbent. A net bag provided with sorbent (active carbon, silica gel etc) is arranged in the outer cover; the net bag can adsorb harmful substance such as moisture, dissociated acid etc produced by liquid which infuses soakage material at the action of electric field to purify soakage material, so the capacitor is of self-purification function; the reliability of capacitor is enhanced, and the service life of the capacitor is greatly prolonged.
Description
Technical field
The utility model belongs to capacitor, particularly relates to a kind of auto purification type capacitor that is applied in the circuit.
Background technology
The high power capacitor of using in circuit such as interchange, direct current, pulse is generally made impregnant with liquid (or gas).Impregnant has good electrical properties and flowability, can improve the radiating condition of capacitor, improves withstand voltage, the partial discharge performance of capacitor and the stability of capacitor electrode performance greatly.But impregnant easily produces harmful substances such as gas, moisture, free acid as the important component part of condenser dielectric under the electric field long term.These materials can't be got rid of, can only be cumulative, and condenser loss is increased, insulation resistance reduces, partial discharge performance and withstand voltage reduction, thus make the whole capacitor device aging, the life-span reduces, and What is more, also may explode.
Summary of the invention
The purpose of this utility model provides a kind of auto purification type capacitor.It has self-purification function, can absorb the harmful substance that impregnant produces in running, makes it remain on premium properties under the initial state, delay the aging of impregnant, that is delay the aging of capacitor, and improve the reliability of capacitor greatly, prolong its useful life.
The purpose of this utility model is achieved in that
A kind of auto purification type capacitor, it comprises core group, shell, impregnant, exit, stiff end, it is characterized in that: the core group has the adsorbent mesh bag outward in the enclosure, and adsorbent is arranged in the mesh bag.
Adsorbent is a silica gel particle.
Adsorbent is an activated carbon granule.
Characteristics of the present utility model are:
Can be adsorbed on harmful substances such as the fluid impregnant produced under the electric field action moisture, free acid, purify impregnant, make capacitor have self-purification function, improve the reliability that capacitor uses, prolong the useful life of capacitor greatly.
Capacitor is in operation, because of variations in temperature and electric field action, impregnant constantly flows in capacitor, when flowing through the adsorbent place, harmful substances such as its moisture that produces under electric field, gas, free acid are adsorbed agent and absorb, thereby reach the purpose of impregnant auto purification, make capacitor have the function of auto purification.Do not make with the material of impregnant generation bad reaction because of mesh bag usefulness, adsorbent is fixed on again in the mesh bag, can not enter core group inside with flowing of impregnant, so their existence can not produce illeffects to capacitor performance.
