Embodiment
Accompanying drawing has provided an embodiment of the present utility model, and the utility model will be further described below in conjunction with accompanying drawing.
From accompanying drawing as can be seen, the utility model comprises vertically insulated sub 8, the joystick 9 of silicon rubber level insulation 1, vacuum bubbles 2, vertical support portion assembling 6, high-pressure section assembling 7, silicon rubber, base plate assembling 10, cylinder transmission assembling 11 and electric control unit assembling 20.Silicon rubber level insulation 1 is installed in the high-pressure section assembling 7, and silicon rubber vertically insulated sub 8 is installed in the vertical support portion assembling 6.The dielectric strength of high voltage input terminal and output when silicon rubber level insulation 1 is used to guarantee the vacuum circuit-breaker gate-dividing state, when silicon rubber vertically insulated sub 8 is used to guarantee the vacuum circuit-breaker "on" position, the dielectric strength between high-pressure section and the low voltage control part.
Cylinder transmission assembling 11 is made up of storage reservoir 13, pressure regulating valve 14, electromagnetically operated valve 15, transmission cylinder 16, piston 17, hold-in winding 18, quick-release mechanism 19; Joystick 9 lower ends are connected with piston 17, and the upper end is connected with vacuum bubbles 2 by crank arm mechanism.
Silicon rubber level insulation son 1 is made up of rear flange 21, horizontal epoxy stringing 22, horizontal silicon rubber full skirt 23, forward flange 24.Rear flange 21 also is the high voltage input terminal of vacuum circuit-breaker simultaneously, for vacuum bubbles 2 stationary contacts provide erection support.Horizontal epoxy stringing 22 is installed cavity for vacuum bubbles 2 provides air-tightness, and horizontal silicon rubber full skirt 23 press-fits in horizontal epoxy stringing 22 outers, guarantees silicon rubber level insulation 1 dielectric strength.Forward flange 24 is connected with driving head 4, guarantees the reliably horizontal installment state of maintenance of vacuum circuit-breaker high-pressure section assembling 7.
