摘要： A gas-insulated switchgear includes a sealed vessel filled with an insulating gas, a circuit breaker held in the sealed vessel, and a branch pipe attached to a lower part of the sealed vessel right below the circuit breaker. The branch pipe defines a hand hole for use in inspecting the circuit breaker, provides a place for installing an absorbent container and forms a foreign matter collecting space.
