POTENTIAL TRANSFORMER ISOLATING DEVICE AND GAS-INSULATED SWITCHGEAR

A potential transformer isolating device comprises a swinging rod (11,31), a guide pole(14,34), and a compression device(13,33). The guide pole (14, 34) has a guide-pole guide end (142,342) and an arc-shaped guide-pole connecting end (141,341). When the guide-pole connecting end (141,341) is under t...

Zusammenfassung:A potential transformer isolating device comprises a swinging rod (11,31), a guide pole(14,34), and a compression device(13,33). The guide pole (14, 34) has a guide-pole guide end (142,342) and an arc-shaped guide-pole connecting end (141,341). When the guide-pole connecting end (141,341) is under the action of the external force, the guide pole can move along the swinging rod (11, 31), and the compression device (13,33) is compressed. When the external force is removed, the guide pole (14, 34) can be reset under the action force of the compression device (13, 33). Therefore, the design of the telescopic round stick is good for improving the insulation levels of the gas insulated switchgear and the control device.
