Comparison of Two Kinds of SF6 Pole Mounted Switches

1. SF6 circuit recloser of pole mounted switch


Structure: SF6 circuit recloser is sulfur hexafluoride circuit breaker. The structure of SF6 circuit breaker is mainly porcelain post structure and tank structure.


Application: SF6 circuit recloser is mainly used in EHV large capacity power system.

Features: SF6 circuit recloser has the characteristics of blocking effect, long electrical life, high insulation level, good sealing performance, self-protection and low operating power.


2. SF6 load break switch


Structure: the structure of SF6 load break switch is mainly arc extinguishing device, using SF6 gas as insulation and arc extinguishing medium.


Application: SF6 load break switch has more application scenarios, one is used to make and break load current and overload current, the other is used to make and break no-load line, no-load transformer and capacitor bank.


Features: SF6 load break switch has the characteristics of long electrical life, strong breaking force, three working positions, small current breaking and strong resistance to harsh environment.
