Application fields and types of high voltage composite dielectric capacitors

Application of high voltage composite dielectric capacitor:

The new composite dielectric capacitor can also be used for high-voltage pulse, high-voltage commutation, locomotive control circuit, radio communication (railway signal, radar communication), filtering, compensation, sudden wave absorption, laser power supply, mine drilling equipment, medium and high frequency equipment, medical equipment, power compensation of power grid, railway electric locomotive system, advanced audio equipment, household appliances, industrial automation Equipment, instrumentation and other fields.

Types of high voltage composite dielectric capacitor

At present, high voltage composite dielectric capacitors include iron shell, aluminum shell and plastic shell (nylon, PBT, etc.).

High voltage composite dielectric capacitors are mainly represented by

1. High voltage composite dielectric capacitor

2. High specific energy high voltage combined capacitor

3. High specific energy high voltage pulse capacitor.

4. Power compensation capacitor, power filter capacitor

Capacitor is a kind of electrical equipment with relatively weak reliability among all kinds of equipment in substation. Compared with other equipment with the same voltage, the insulation of capacitor is weaker, the internal components have more heat, and the heat dissipation is not good. There are many internal failure opportunities. The combustible composition of the internal material of power capacitor is large, so it is easy to catch fire in operation. Therefore, good low temperature and ventilation conditions should be created as far as possible for the operation of capacitor.
