Title:
SYSTEM FOR GENERATING SOLID DISCHARGE RESULTANT OF SF6 FOR DC WALL BUSHING
Document Type and Number:
WIPO Patent Application WO/2019/006816
Kind Code:
A1
Abstract:
A system for generating a solid discharge resultant of SF6 for a DC wall bushing comprises an alternating current power source, a voltage regulator, a transformer, a high-voltage silicon rectifier stack, a charging resistor, a pulse capacitor, a discharge cavity, a metal electrode, a resistance-capacitance voltage divider, a current sensor, a solid resultant collection device, and an oscilloscope. The system can simulate various manners of discharge and gas states of an SF6 gas in a DC wall bushing and generation of a solid resultant under the metal electrode, such that a discharge voltage and current can be accurately measured. The solid resultant collection device can effectively collect a solid resultant generated after discharge, such that a further qualitative and quantitative analysis of the generated solid resultant can be performed conveniently.
