摘要:
A reliable, compact vacuum switchgear is provided at an inexpensive cost. The vacuum switchgear comprises a switch 1 having a fixed electrode 12 and a movable electrode 13 connectable to and disconnectable from the fixed electrode 12, another switch 2 having a fixed electrode 22 and a movable electrode 23 connectable to and disconnectable from the fixed electrode 22, conductors 3 connected to the fixed electrodes 12, 22 of the switches 1, 2, earth switches 4 connected to the conductors 3, a mold section 7 formed by molding the conductors 3 and the earth switches 4 with resin, and a vacuum container 8 accommodating the switches 1, 2 and disposed on the mold section 7.
