Specific embodiment

In order that content of the present utility model is easier to be clearly understood, below according to specific embodiment and with reference to attached Figure, is described in further detail to this utility model.

As shown in figure 1, a kind of idle intelligent compensation filter, it includes exchanging self-healing filter capacitor 3, described friendship Stream self-healing filter capacitor 3 has：

Body 31, described body 31 has shell；

Metallic conductor 32, described metallic conductor 32 stretches out outside shell, and stretches out the part bag of shell on metallic conductor 32 Wrap up in insulator 33, described insulator 33 be porcelain cylinder, and porcelain cylinder by multiple skirt umbrellas along metallic conductor 32 axle It is formed by connecting in stacked.

It is stacked that the material of original insulator and moulding are replaced by porcelain skirt-type by short plastics cube by this utility model Cylinder, can increase alternate creep age distance effectively, and the thermostability of porcelain body and anti-flammability improve the reliability of product, safety, Also extend the service life of product simultaneously.
