ELECTRIC CONTACT GREASE AND CURRENT-CARRYING SLIDING STRUCTURES, POWER SWITCH, VACUUM CIRCUIT BREAKER, AND VACUUM INSULATED SWITCH GEAR AND ASSEMBLING METHOD FOR VACUUM INSULATED SWITCH GEAR

摘要

PURPOSE: A grease for electrical contact, a slide current carrying structure, a power switch, a vacuum circuit breaker, vacuum insulated switchgear and an assembly method of the vacuum insulated switchgear are provided to maximize a lubricating effect of the grease by preventing spill due to gravity or vibration. CONSTITUTION: A vacuum valve(1) has a pair of contact points. A fixed terminal(70) is connected to the vacuum valve. An insulated tube(72) covers the fixed terminal and a movable terminal(71). An insulated operating rod(73) is connected to the movable terminal. A main lever(75) connects a wiping mechanism(74) and the operating rod.
