Sulfur hexafluoride (SF6) is a colorless, odorless, non-toxic gas, its molecular structure is stable, not easy to react with other substances and has excellent insulation properties and stable chemical properties, as well as non-toxic, non-corrosive and other characteristics, so it is widely used in power equipment.
The following is a summary of how sulfur hexafluoride gas works on circuit breakers:
1. Insulation performance: sulfur hexafluoride gas insulation performance is very good, its electrical strength is about 3 times that of air, so it can be used as an insulating medium in the power system. In circuit breakers, sulfur hexafluoride gas is used to isolate electrical components and circuits, preventing current leakage and short circuits between electrical components.
2. Arc extinguishing performance: sulfur hexafluoride gas has good arc extinguishing performance at high temperature, which can quickly absorb the energy generated by the arc and extinguish the arc quickly. Therefore, in circuit breakers, sulfur hexafluoride gas can be used to generate and extinguish arcs.
3. Stability: sulfur hexafluoride gas is gaseous at room temperature and pressure, and its chemical properties are stable, and it is not easy to react with other substances. Therefore, in the circuit breaker, sulfur hexafluoride gas can work stably for a long time without negatively affecting the performance of the circuit breaker.
4. Safety: sulfur hexafluoride gas is non-toxic and harmless to the human body, so there is no need to worry about the safety of sulfur hexafluoride gas when using circuit breakers.
