The lower end of extraction cable is welded to connect with capacitor body realization, then carries out electricity by epoxy resin filling into shell again
The encapsulation positioning of container fuse.This non-cover type epoxy resin encapsulation capacitor has as a drawback that：
1st, from a structural point, due to uncovered on this kind of capacitor case, extraction cable can not position, in this way
It is not only an impediment to encapsulate, is also unfavorable for product beauty.
2nd, for filling process, this kind of capacitor is needed using multiple filling, such as first time filling a small amount of ring of multipass
The purpose of oxygen resin is first fixed capacity device fuse, then gradually filling epoxy resin again, is finished until filling.
2nd, there is lid formula epoxy resin encapsulation capacitor：It includes a shell and the cover that can be covered in shell aperture end, should
The location hole for positioning extraction cable is provided in cover；A capacitor body, an extraction cable are housed in the shell
Lower end location hole and capacitor body in cover is passed through to realize be welded to connect, then pass through asphalt mixtures modified by epoxy resin filling into shell again
Fat carries out the encapsulation positioning of capacitor body.Compared with the epoxy resin encapsulation capacitor of non-cover type, its advantage is can be with
Outgoing cable line position is positioned, is conducive to the beauty of capacitor product.But its shortcomings that, is：Enclosure with
There are gap between capacitor body, core is placed in plastic housing cannot be placed in the middle, and epoxy encapsulating is uneven, leads to core poor sealing
And heat dissipation is bad, air can not be completely exhausted out and cause epoxy resin from being filled up completely during filling epoxy resin, shadow
Ring the performance to product.
