| 真空断路器与其他高压断路器相比具有较多优点。 Compared with other high-voltage circuit breakers, vacuum circuit breaker has many advantages. (1)在密封的容器中真空熄弧效果好，电弧和炽热气体不外露。 (1) in sealed container, the effect of vacuum arc extinguishing is good, and the arc and hot gas are not exposed. (2)触头问隙很少。 (2) the gap of contact is very little. (3)燃弧时间短，电压低，能量小，触头磨耗少，允许的开断次数多。 (3) short arcing time, low voltage, low energy consumption, less contact wear, and more opening and closing times. (4)动导电杆的惯性小，适宜频繁操作。 (4) the inertia of the movable conducting pole is small, so it is suitable for frequent operation. (5)操作机构小及结构简单，整体体积小，重量轻。 (5) the operating mechanism is small and the structure is simple, the whole volume is small, and the weight is light. (6))操作时噪声小。 (6) noise is small during operation. (7)无火灾和爆炸燃火的危险。 (7) risk of fire without explosion and fire. (8)触头部分为完全密封结构，不容易因潮气、灰尘、有害气体等影响而降低它的性能，运行可靠。 (8) the contact part is completely sealed structure, and it is not easy to reduce its performance because of humidity, dust, harmful gas and so on. It is reliable in operation. |
