| Zusammenfassung: | The utility model discloses an isolating switch porcelain knob insulating barrier which comprises an insulating square board (3) and two insulating movable boards (1). The middle part of the lower side of the insulating square board (3) is provided with two semispherical gaps (6). Two corners of the upper side of the insulating square board (3) are connected with the two insulating movable boards (1) through rotating pins (2). The two insulating movable boards (1) can rotate in the plane with the insulating square board (3) around the rotating pins (2). The two insulating movable boards (1) are respectively provided with an arc-shaped channel section (4). The isolating switch porcelain knob insulating barrier has the following advantages: simple structure, convenient operation, capability of effectively insulating and isolating the porcelain knob, capability of preventing a problem of grounding shortcircuit in performing replacement and defect elimination on the isolating switch, high clamping effect, high in |
