LW67-550 type tank SF6 circuit breaker adopts double-break structure with parallel capacitors between breaks, and closing resistors can be optionally configured according to user requirements. Each product consists of three independently operable poles and one control cabinet. Each pole includes arc extinguishing chamber, operating mechanism, outgoing bushing, current transformer and tank body. Each pole of the product is equipped with its own hydraulic disc spring operating mechanism, single-pole operation, and three-pole electrical linkage operation can also be performed.
Product Features
- The arc extinguishing chamber adopts the world's advanced single-pressure bidirectional synchronous air-blast method, with excellent breaking capability;
- Exclusive outdoor protection structure, corrosion resistant;
- Strong earthquake resistance;
- Light weight of the whole machine, small operating work, small load on the foundation, saving civil engineering costs;
- Full aluminum alloy housing, low loss;
- The circuit breaker integrates through-type current transformer, no separate CT is needed;
- On-site installation is simpler than GIS, no need to deal with busbar docking;
- Price is lower than GIS.
