Gas-insulated switchgear apparatus.

摘要

A gas-insulated switchgear apparatus includes a three-phase circuit breaker (4), a three-phase disconnecting switch (6) and a cable head (8), with the disconnecting switch (6) and the cable head (8) being accommodated in a cable-head housing (8a). To minimize the size of the disconnecting switch (6). movable insulators (14) connected to movable conductors (12) and stationary insulators (15) supporting connecting conductors (13) are arranged so that the movable and stationary insulators (14, 15) form triangles disposed substantially in the same plane with the respective triangles being inverted in relation to each other.
