GAS INSULATION SWITCHGEAR

摘要

PURPOSE: A gas insulation switchgear is provided to improve dielectric strength by forming a guide for discharging hot gas directly and minimizing melting loss. CONSTITUTION: A fixture of a circuit breaker for a gas insulation switchgear includes a fixing chamber(220), a fixed arc contactor(221), a main shield(230), and a secondary shield(240). The fixing chamber comprises a fixing main contactor(222) and a plurality of first Exhaust holes(223). The fixed arc contactor is connected to the operation arc connector of the movable unit. The main shield protects the circumference of the fixing chamber. The main shield comprises a second exhausting hole(231). The secondary shield guides the flow of the hot gas to the backward.
