发明名称 HV potential measurement in encapsulated metal switch - has capacitive sensor consisting of burst disc and insulated plate
摘要 <p>A device for measuring a high voltage potential in metal capsulated press. sealed high voltage switches has an electrode with the conductor carrying the high voltage. The capacitive voltage measurement avoids penetration of the pressurised gas volume and the use of a pressure tight connection. The electrode consists wholly or partly of a burst disc (7) sealing an opening (4) of the metal capsule (1) with intermediate insulating layers (8, 9). When a defined pressure is exceeded the disc bursts and relieves the pressure. A second metal sheet (13) is insulated from the disc.</p>
