this paper emphasizes on the influences of arc energy by the contact breakaway initial velocity that is the velocity of moving contact at the time of moving contact and stationary contact breaking.
研究了触点分离初速度(动触点与静触点刚刚分离时刻的动触点速度)对电弧能量的影响。
the first section (141) bears resiliently against the rotor periphery for sliding contact with the moving contact parts (132/133).
第一部分(141)弹性支撑在转子外周上,用于与移动接触件部件(132/133)滑动接触。
the results show that the position of the exhausting gas hole and the arc heat effects on the gas inside the hollow moving contact have obviously raised the pressure rising speed.
利用它对国产ofpi—220型sf_6断路器进行的计算结果表明,改变动触头排气孔位置及电弧对动触头内腔中气体的热效应可明显提高开断电流时灭弧室压力上升速度。
the moving contact is formed by a deep drawing process and at least one part (132) has an undulating profile matching with that of an adjacent part of the rotor periphery.
所述移动接触件通过深沖压工艺制造,其至少一个部分(132)具有与转子外周的相邻部分的外形相匹配的波形轮廓。
a permanent magnet and a moving contact are fixed on a swing plate which can deflect, and the top end of the swing plate is hung on a coil brace through a spring.
永久磁铁和动触头固定在摆动板上,摆动板可偏转,顶端通过弹簧吊置在线圈支架上。
the invention includes insulating cylinder, fixed contact and moving contact set in the insulating cylinder.
本发明涉及一种电力设备使用的特高压开关倍速分断触头。
the reaction springs are arranged in the upper and lower moving contact pedestals, thus the dropout fuse ensures the junction to be good in contact, and is durable.
使用本发明因上动触头座和下动触头座内设置了反作用弹簧,使接点变得接触良好,长久耐用。
the entire switch without a moving contact surface has high explosion proof and waterproof function, meeting the requirement of chemical industries, coal mines, underwater, and milling working.
整个开关没有动接触面。所以具有较高的防爆防水性能。满足化工,煤矿、水下,制粉作业的要求。
blow open force has important effect on the motion status of the moving contact after it separates from the static one, and which affects the performance of low voltage electric apparatus.
气动斥力对于低压电器中动触头斥开后的运动状态起着重要作用,影响其性能。
a fifth fixed contact (150) extends through one side of the switch and provides the continous connection with the moving contact parts.
第五固定接触件(150)穿过开关的一侧延伸,提供与移动接触件的连续连接。
when the fuse is blown out, the rotary link piece and the lower moving contact droop to indicate failure occurrence.
当熔丝熔断时,转动连片和下动触头下垂,即可显示发生故障。
