Description

technical field [0001] The invention relates to a switch in the electrical field, in particular to an air type reversing isolation device used in an underground high-voltage explosion-proof electromagnetic starter in coal mines. Background technique [0002] At present, there are only 3300V, 600A switches produced by ALENWESTWALLANCTOWN Company for high-pressure air type reversing isolating switches in coal mines. The axis of the operating mechanism of the switch is the same as the rotating shaft of the main switch moving contact and the rotating shaft of the control switch moving contact, and along the axial direction, the three-phase static contact of the main switch and two static contacts of the control switch are arranged in sequence. The switch has four positions in the clockwise direction, that is, the main switch is closed in the forward direction, the main switch is stopped, and the control switch test is closed in the reverse direction of the main switch. When the...
