Summary of the invention

The purpose of this utility model is to have the problems referred to above for existing technology, has proposedThereby one makes oil can not be penetrated into metalized film and upper and lower metal spraying on upper and lower gilding layerThe oil immersed type capacitor that layer contact position there will not be scintillation to puncture.

The purpose of this utility model can realize by following technical proposal: a kind of oil immersed typeCapacitor, comprises that shell, cap, electric wire are reached the standard grade, electric wire rolls off the production line and capacitor body,The inner chamber that forms sealing between described shell and cap, above-mentioned capacitor body is positioned at inner chamberIn and comprise the upper gilding layer that is positioned at upper surface and the lower gilding layer that is positioned at lower surface, electric capacityIn device fuse, metalized film is installed, described capacitor body has centre bore, above-mentioned electricityStretch out outside cap the line one end of reaching the standard grade, the other end be electrically connected with upper gilding layer and this end on lineCore is exposed, and stretch out outside cap the described electric wire one end of rolling off the production line, and the other end is through in above-mentionedHeart hole be electrically connected with lower gilding layer and this end on core be exposed, it is characterized in that,Described electric wire is reached the standard grade and electric wire that electrical connection with upper gilding layer and lower gilding layer respectively that roll off the production lineHold on exposed core and be coated with epoxy resin layer.

In above-mentioned a kind of oil immersed type capacitor, described upper gilding layer and lower gilding layerOn be respectively arranged with scolding tin contact, said wires is reached the standard grade and electric wire rolls off the production line and passes through respectively scolding tinContact is realized and being electrically connected with upper gilding layer and lower gilding layer.

In above-mentioned a kind of oil immersed type capacitor, described electric wire rolls off the production line and exists through capIn inner chamber, after 90-degree bent, be electrically connected with lower gilding layer by centre bore again.

Compared with prior art, this oil immersed type capacitor can prevent that extraneous oil is by electricityThe gap that line is reached the standard grade and electric wire rolls off the production line between its line skin and core is penetrated into respectively gilding layerOccur with the phenomenon of lower gilding layer, thereby make metalized film and upper and lower gilding layer contact positionThere will not be scintillation to puncture.

Detailed description of the invention

Below specific embodiment of the utility model by reference to the accompanying drawings, to the utility modelTechnical scheme be further described, but the utility model is not limited to these embodiment.

As illustrated in fig. 1 and 2, this oil immersed type capacitor comprises shell 1, cap 2, electric wireReach the standard grade 3, electric wire rolls off the production line 4 and capacitor body 5, forms close between shell 1 and cap 2The inner chamber of envelope, capacitor body 5 is arranged in inner chamber and comprises the upper metal spraying that is positioned at upper surfaceLayer 51 and the lower gilding layer 52 that is positioned at lower surface, be provided with metal in capacitor body 5Change film 53, capacitor body 5 has centre bore, and cap 2 is stretched out in electric wire 3 one end of reaching the standard gradeOutward, the other end be electrically connected with upper gilding layer 51 and this end on core 7 be exposed, electricityStretch out outside cap 2 line 4 one end of rolling off the production line, and the other end is through centre bore and lower gilding layer 52Electrical connection and this end on core 7 be exposed, electric wire reach the standard grade 3 and electric wire roll off the production line 4 pointsBag on the exposed core 7 of that end of not being electrically connected with upper gilding layer 51 and lower gilding layer 52Be covered with epoxy resin layer 8.
