FLN44-12D/T630-20型户内高压六氟化硫负荷开关及其组合电器 FLN44-12D/T630-20型户内高压六氟化硫负荷开关及其组合电器以六氟化硫气体作为绝缘和灭弧介质,采用独特的直动压气式原理开断和灭弧。产品结构新颖紧凑。负荷开关和接地开关置于同一个充满SF_6气体的不锈钢罐体内并罐体可靠接地。当六氟化硫负倚开关一熔断器组合电器有短路或过载电流通过,任一
FLN44-12D/T630-20 indoor high-pressure SF6 load switch and its combination FLN44-12D/T630-20 indoor high-pressure SF6 load switch and its combination SF6 gas as insulation And the arc extinguishing medium uses a unique direct-acting pneumatic pressure principle to break and extinguish the arc. The product structure is novel and compact. The load switch and grounding switch are placed in the same stainless steel tank filled with SF_6 gas and the tank is reliably grounded. When the SF 6 gravity-fed switch-fuse combination has a short-circuit or overload current, either
