HIGH-CAPACITY CERAMIC COUPLING CAPACITOR FOR MEASURING PARTIAL DISCHARGE

摘要

PURPOSE: A high-capacity ceramic coupling capacitor for measuring partial discharge is provided to measure the partial discharge of a high-capacity electric device and decide an insulating state of the high-capacity electric device by connecting ceramic bodies serially or in parallel to each other. CONSTITUTION: A high-capacity ceramic coupling capacitor for measuring partial discharge includes an insulating cabinet(51) and a plurality of ceramic bodies(54,55). The insulating cabinet(51) has an empty inside region. The ceramic bodies(54,55) are installed in the inside of the insulating cabinet. The ceramic bodies(54,55) are connected in parallel to each other. A parallel connection structure of the ceramic bodies(54,55) is formed by laminating one or more layer around one ceramic body.
