Description

Before assembling. lhe vacuum interrupter should be cleared by cotton or silk with alcohol; meanwhile, the conducting rods and the connections should be cleared so as to ensure the vacuum Interrupters in good contact with the switchgears. Vacuum interrupters should be assembled and adjusted In accordmg to assembling requests of circuit breakers; but ail mechanical parameters of the vacuum switches should mect up with the requirements of vacuum interrupters. It is never allowed to strike or hit vacuum interrupters v/hüe assembling or adjustment. When the plate is connected to the fixed terminal of vacuum interrupters with bolts, screw-m depth into the vacuum interrupters should be less than the depth of thread marked on the technlcal drawmgs of interrupters. As showed in Pic.1 and Pic.2. in order to ensure the safety of métal bellows, when mounting the insulation push rod. the movable stem should be fixed up with a clamper through the Slot (if there is any). |f there is no slot or vacuum interrupters are used for the making of embeddcd pôles, plcasc take rcfcrence to the antitwist torque force given in its spécifications. When the tightening force is smaller than the anti-twist torque force, a torque spanner should be used to tighten the insulated push rod. Detailed tightening torque values are given in the form attached. When the tightening torque force is higher than the anti-twist torque force, the insulating push rod should be mounted in the manner showed in Plc.2, which will prevent from the moving of the stem and the twisting of the métal
