The Difference Between SF6 Circuit Breaker and SF6 Load Break Switch

1. Introduction of sf6 load break switch and sf6 circuit breaker

(1) SF6 circuit breaker auto circuit recloser

Sulfur hexafluoride circuit breaker is a circuit breaker that uses sulfur hexafluoride (SF6) gas as arc extinguishing medium and insulating medium, referred to as SF6 circuit breaker. The use of sulfur hexafluoride as an arc extinguishing medium in circuit breakers began in the early 1950s. Due to the excellent characteristics of this gas, the single-break of this recloser vacuum circuit breaker is much higher than the compressed air circuit breaker and the oil-less circuit breaker in terms of voltage and current parameters, and does not require high air pressure and a considerable number of series-connected breaks.

(2) sf6 load break switch

sf6 load break switch is an excellent load switch experienced by many users in recent years. In addition to the long electrical life and strong breaking force, it has the same advantages as the vacuum load switch. Its outstanding advantage is that it is easy to realize three working positions (on, off and ground), small current (inductance, capacitor) breaking, strong resistance to harsh environmental conditions. It is suitable for promotion and application in urban and rural medium-voltage power distribution box networks. The load switch is a switching appliance with a simple arc extinguishing device. The load switch using SF6 gas as the insulation and arc extinguishing medium is called sf6 load break switch, which can be used as a closing and breaking load current. It can also be used for closing and breaking no-load lines, no-load transformers and capacitor banks, etc. All three-position load switches with on, off and grounding functions have simple structure and low price. Only the load switch cannot disconnect the short-circuit current. We have 11kv vacuum circuit breaker, 24kv vacuum circuit breaker and 33kv auto recloser.

2. The difference between sf6 circuit breaker and sf6 load break switch

(1) Structure

sf6 circuit breaker: sf6 circuit breaker is a sulfur hexafluoride circuit breaker, and the structure of sf6 circuit breaker is mainly a porcelain column structure and a tank structure.

sf6 pole mounted load break switch: the structure of sf6 load break switch is mainly arc extinguishing device, using sf6 gas as insulation and arc extinguishing medium.

(2) Application

sf6 circuit breaker: sf6 circuit breaker is mainly used in ultra-high voltage large-capacity power systems.

sf6 LBS pole mounted switch: sf6 load break switch has a larger application scenario, one is used as a closing and breaking load current and overload current. The other is for closing and breaking no-load lines, no-load transformers and capacitor banks.

(3) Features

sf6 circuit breaker: sf6 circuit breaker has the characteristics of blocking effect, long electrical life, high insulation level, good sealing performance, smooth buffering and low operating power.

sf6 LBS pole mounted load break switch: 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 environmental conditions. Gopower manufacturer high quality 11kv lbs and 15 kv pole mounted disconnect switch.
