Document Type and Number:
Japanese Patent JP5215237
Kind Code:
B2
Abstract:
A switchgear is designed to resolve a problem that three insolating levers and folding parts are required for great load rated voltage, middle load rated voltage and small load rated voltage. The switchgear comprises an operating mechanism part (14) having an operating lever (14b) connected to one side of a driving lever (16) which is fixedly connected with a support lever (15) vertical to a switch direction of electrodes of a vacuum interrupter (1); an insolating lever (13), one side of which is connected with a movable energization shaft (8) of the vacuum interrupter (1) and the other side is connected with the other side of the driving lever (16), so as to switch the electrodes of the vacuum interrupter (1); a metallic isolation edge face distance adjustment device (19), one side (19a)of which is arranged between one side (13a) and the other side (13b) of the insolating lever (13) by a prescribed interspace with the folding parts and periphery part of the isolating lever (13), the other side (19b) is mounted on a component, e.g. a base station frame (3) arranged on a ground potential side.
