The dry high high-voltage parallel capacitor is applied in the AC power system with any standard voltage grades with the frequency of 50HZ, voltage grade of 6-66kV so as to enhance the grid power factors, reduce the line loss, improve the system voltage and increase the transmission capacity of the power transmission and transformation device. As the product is of the dry oil-free structure, therefore it is non-flammable, non-explosive and non-polluting; therefore it is especially suitable to the transformer stations in the center and under the ground of the cities.
All of the dry high-voltage parallel capacitor devices are of the dry oil-free structure; therefore the environmental pollution caused by the oil leakage of the oil-dipped equipment has been avoided.
The internal components of the capacitor have the self-healing performance: when the polypropylene film as the dielectric has been broken down, the high heat of products at the breakdown point will dissipate the metal coating around the breakdown points rapidly to form the metal blank area for the conductive metallic coating is pretty think; the breakdown point will resume insulating automatically and the capacitor shall work normally.
The internal components of the capacitor adopt the unique Ag-Zn compound metallic coating as well as the edge thickening technology and the metal spraying process, so that the capacitor has the advantages of small capacitance loss, good self-healing performance and powerful anti-surge capacity; therefore it has guaranteed the reliable operation of the capacitor.
The internal components of the capacitor adopt the unique inner fuse wire protection (patent) to make the damaged components reliably isolated to make sure they won’t be re-stricken after being fused.
The capacitor unit adopts the unique vermiculite protection (patent) to endow it the characteristics of non-flammable and non-explosive, safe and reliable.
The capacitor unit adopts the plastic-sprayed shell that hasn’t been sealed; the shell is not only beautiful but also improves the anti-corrosion capacity of the capacitor shell.
The capacitor unit is of small volume, light weight (and the ratio characteristic is0.23kg/kvar), it can be placed vertically and horizontally so as to strengthen the product adaptation.
