SF6 气体应用
当高压断路器(又称高压开关)在开断电路时会有火花产生又称之为电弧,在电气设备中电弧的产生会对断路器造成烧毁甚至发生爆炸的危害。SF6 气体由于具有绝缘性能好灭弧能力强的特性,目前在高压断路器中被广泛使用。SF6 气体在电力设备中的灭弧性能取决于设备容器中的SF6气体的密度。如在不同型号、规格的断路器中的SF6气体的密度就是不相同的,如果SF6气体由于泄漏,密度减小,则灭弧作用就会减弱或起不到灭弧作用,因此,用SF6密度表对容器内SF6气体的密度进行监视和控制就显得格外重要。
SF6 gas intended
The spark happened when the electric switchingor the high pressure breaker (high pressure switch)open or close circuit is the electric arc. The electric arcproduced in the electrical equipment may lead thecircuit breaker to burn down even explosive. The SF6gas is widely used in the high-pressured electric appliance because it has the insulating ability of extin- guishing arc.The ability of The SF6 gas extinguishing arc has big relations with the SF6 gas density in the equip-ment vessel. In the different model, specification cir-cuit breaker SF6 gas density is different, when the density SF6 gas is lower than some value, the extin-guishing arc function is weaken, therefore, it is impor-tant that carrying on the surveillance and the control of the SF6 gas density .
