1.Short arc extinguishing time, good insulation recovery performance, low contact point consumption, and there is no need to replace and maintain the switch.
2.Two kinds of spring energy storage operating mechanism are adopted, and the closing and opening time is short.
3.The switch can also ensure the rated insulation level and breaking capacity of the switch under zero gauge pressure (0k·· 1=0.0MPa).
4.Install high-pressure explosion-proof pressure relief device.
5.The switch has a low-pressure locking alarm device and a manual locking device.
6.Built-in three current transformers, one set of zero sequence current transformers and six voltage transformers.
7.Equipped with CT/ZCT protection device and open circuit and voltage sensor protection device.
