静触点

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。

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 .

提出镶嵌式静触点能降低成本，并能适应恶劣的使用环境。

The mosaic fixed contact can reduce cost and are suitable for bad operating environment .

指出了静触点结构、回位弹簧弹力以及通电方式是影响电磁开关粘连的主要因素；

The structure of fixed contact , return spring and conduction ways are the major factors influencing the power-on of electromagnetic switch .

所述压力传感器和温度传感器通过各自的动、静触点和导线以及公共的动、静触点控制的报警电路。

The pressure sensor and temperature sensor control the warning circuit via respective dynamic and static contact , led as well as common dynamic and static contact .

分析了产生动熔焊的3种时刻，分别为动、静触点闭合接触瞬间，接触短弹跳分离瞬间和触点弹跳后的闭合接触瞬间。

The 3 possible time points of welding occurrence , which includes the touching instant when contacts close , separation stage when contact bounces and closing instant after contact bounces , were analyzed .

由于该类型熔断器的对地安全距离至少为4.5米，且其上部静触点的弹簧压力亦很大，因此人工操作熔管的分合不仅具有相当的难度，且操作过程中的不安全因素甚多。

Calculation of Energizing Spring Force in Roller-type Overrunning Clutches Due to the great pressure from the spring of upper static interface , it is obvious that there are not only many difficulties , but also many insecure factors in artificial operation , especially when it is raining .
