F9 series Auxiliary Switch for electrical switchge

Application This series applies to the HV operating mechanism's switching on, switching off, interlock, and controlling of signal circuit. It also applies to HV switchgears, and can be used as transfer switch of cubicle switch. Working Conditions Ambient Temperature (- 40 °c 40 °c )Height above sea Level (h < 3000m )Monthly mean relative air humidity < 90 %, Daily mean relative air humidity < 95 %Oscillatory accelecation < 15m/s2Situation of no sharp pounding, no explosion risk, no inductive dust, no air destrying insulators or corroding metal and so on. F9 series is composed of several layers. Inner structure of F9 series as below: Numbers on both sides of the upward part stand for the contacts. In each layer, the contacts on diagonal line construct a NO/NC circuit, which is achieved by the sign on the operating shaft, The contact of dynamic & static contacts adopt circumference slide compression type, and pressure between contacts comes from specific compression spring, which is non-conductive and far away from the running part. In addition, the turning part joint of the static contact is welded by bare copper wire, and this makes the through-flow be more reliable. Delay quick-acting mechanism has flexible operation, delays exactly, and cuts over rapidly. Quick-acting mechanism begins to force the dynamic contact to move quickly when the master arm turns to 65 ° 75 °, and stop at the final position. Thus, it achieves both delay and quick-acting functions. Other types for your reference: 1.F9-18I/W 2.
