Title: Switchgear

Abstract: A switchgear includes a chassis which is partitioned by metal earthed plates and includes a bus bar section located at a central portion, a switch section located below the bus bar section, a cable section located at a rear surface side, and a control section located at a front surface side; an air-insulated earthed disconnecting switch provided in the switch section; and a manipulating device. The switch section is separable from the chassis, and is configured as a case having a semi-closed structure which allows air to pass therethrough but prevents particles of oil and water from passing therethrough.
