Product overview
Capacitive voltage transformers are widely used in AC power systems for measurement, control, protection and high-frequency carrier communication.
Structural features
Capacitive voltage transformer consists of capacitive voltage divider and electromagnetic unit
The electromagnetic unit has a fully sealed structure. The box is equipped with medium-voltage transformers, compensation reactors, dampers, etc. The insulating oil is made of high-quality mineral oil, and the secondary wiring board is cast with epoxy casting or SMC material to effectively prevent leakage. . The accuracy of capacitive voltage transformers can be adjusted on site when the user needs it.
A capacitive voltage divider consists of a high voltage capacitor and a medium voltage capacitor. The capacitor has a fully sealed structure, and is composed of many identical capacitor elements connected in series inside and housed in an insulating shell. The solid dielectric material is a composite of high-quality polypropylene film and paper, the impregnating agent is high-quality synthetic insulating oil, and the capacitor has been fully dried and vacuum impregnated.
