Claims

[Scope of utility model registration request]

In a three-phase gas insulated switchgear with a double busbar and two breaker type line, the circuit breakers on the A side and the B side are connected via a through-type current transformer installed at one outlet of the breaker. A gas-insulated switchgear in which a joint bus bar that is drawn out as a circuit is configured as a three-phase lumped bus bar, and a track single-phase joint bus bar is derived from the three-phase lumped bus bar.
