Embodiment Construction
[0016] The embodiments of the present invention will be described in further detail below according to the above-mentioned drawings.
[0017] see Figure 1~4 As shown, the outdoor high-voltage isolating switch closing and opening device includes a movable blade 1 hingedly connected to an insulator 6 and a static blade 9 fixed on another insulator 13, and the moving blade and the static blade constitute the closing and opening of the outdoor high-voltage isolating switch. The opening and closing of the break is realized by the insulating pull rod 7. The top of the insulating pull rod passes through the through slot in the middle of the two overlapping moving blades, and the pin shaft forms a hinged relationship with the moving blade, and the hinge hole of the insulating pull rod is elongated. Hole 5, the top of which is connected with a steel wire stay rope 3, the stay rope goes around the pulley 4 connected to the inner cavity of the moving blade and passes through the spring ...

This invention discloses a shut up-down gate device of the outdoor high-pressure insulation switch, which is composed of the slider which is on the moving-blade, spring, chain wheel, splint which is on the drawing-rope and stator-blade, replacement spring, bending guide rod and so on. This device pulls the elongated hole which is changed from the insulated drawing-pole's hinged hole of the moving-blade's whole gate and pushes that of the moving-blade's branch gate, which divide the shutting up-down action into two courses, that is when shutting the gate down, firstly shutting the moving-blade down, then compacting the moving-blade by the bending pole when it is nearly up to the location; when shutting the gate up, firstly releasing the pressure on the stator-blade from the moving-blade, then making the moving-blade get off from the stator-blade to shut up the gate. This device can make sure of the credibility of the shutting up-down action and the safety of the high pressure power distribution circuit operation, which has a nice using effect.
Description
technical field [0001] The invention relates to an outdoor high-voltage isolating switch closing and opening device. Background technique [0002] The closing and opening of the three-phase linkage of the outdoor high-voltage isolating switch is realized through the combination of the movable blade and the static blade. In order to ensure better electrification performance, the combination of the fracture must have a certain compression force. Satisfy this certain pressing force, prior art is to realize by screw, spring compression, while requiring certain pressing force, requires moving and static blade to separate again, realizes usually with electric or manual. However, when the contacts of the movable blade and the static blade are corroded due to long-term work in the harsh field environment, the dynamic and static blades of the outdoor high-voltage isolating switch running on the high-voltage distribution line will be "not in place and cannot be separated." "The fatal...
