It indicates that the rotary-arc gap switch employing a sharp knife-edge electrode as a third trigger electrode can distinctly reduce the electrode erosion and prolong the lifetime of the switch.
在不同开关结构、不同电极材料和不同电流波形情况下对开关进行了单次触发放电实验，验证了旋转电弧、场畸变间隙开关能够有效地减轻开关电极的烧蚀程度；
And has a CNC vertical lathe, boring machine large landing, automatic gap submerged arc welding, electro-optical tracking cutting machine and a variety of measurement test equipment.
且拥有数控立式车床、大型落地镗床、自动间隙埋弧焊、光电跟踪切割机以及各类计量检测设备。
Such horizontal magnetic field will make the arc move out of the electrode gap, and reduce the interrupting ability of the vacuum interrupters.
这一横向磁场会将电弧吹向弧隙外侧，削弱了真空灭弧室的开断能力。
