Vacuum insulated switchgear

A vacuum insulated switchgear comprising:

• a housing enclosing a control compartment, a switch compartment, and a busbar compartment, each of the three compartments being partitioned by a metallic earthing plate;
• a circuit-breaking/disconnecting switch region provided in the switch compartment;
• an operating device for the switch region;
• two sets of earthing switch regions provided in the switch compartment;
• an operating device for each of the earthing switch regions;
• a first busbar and a second busbar extended from an adjacent panel, in the busbar compartment;
• and
• a first busbar-connecting bushing and a second busbar-connecting bushing provided in the busbar compartment, the bushings each making the first and second busbars connectible/disconnectible;
• the switch region, the earthing switch regions, the first busbar-connecting bushing, and the second busbar-connecting bushing being integrally molded to form a switch provided on an electrical phase-by-phase basis independently,
• wherein the switches for three phases are arranged in order side by side in the housing, in a longitudinal direction of the housing as viewed from its front;
• the first busbar-connecting bushing in each switch is located to a left side of the housing front, and the second busbar-connecting bushing is located to a right side of the housing front;
• the operating device for the switch region is disposed centrally with respect to the housing front, and the operating devices for the two sets of earthing switch regions are located to left and right sides of the operating device for the switch region;
• and the operating devices for the two sets of earthing switch regions include a handle insertion member disposed at the front side of the housing.
