Spannungswandler für eine metallgekapselte elektrische Schaltanlage

摘要

The invention concerns a voltage transformer (3, 4, 6) for metal-clad electric switchgear. The voltage transformer (3, 4, 6) comprises a measuring electrode (4), which surrounds a high-voltage conductor (7), and an outer electrode (3), which is connected to the measuring electrode (4) by means of an insulating layer (6). According to the invention, the voltage transformer (3, 4, 6) is formed such that the outer electrode (3) is connected in a supporting manner to the metal cladding (1) of the switchgear, and such that the measuring electrode (4) is connected in a supporting manner to the outer electrode (3) by means of a casting resin (6) poured in between the measuring electrode (4) and the outer electrode (3).
