Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the right view of Fig. 1.
Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
Shown in Fig. 1,2, comprise support 1, driving member 2, separating brake extension spring 3, insulated column 4, isolation knife 5, upper bracket 6, guidance panel 7, vacuum interrupter 8, retainer 9, lower carriage 10, fairlead 11, adjustment screw 12, insulation pull bar 13, isolation switch handle 14, vacuum close arc chamber switch knob 15, the close arc chamber opening button 16 of vacuum, connecting rod 17, pull bar 18, input pile crown 19, first conducting block 20, second conducting block 21 etc.
As Fig. 1, shown in Fig. 2, the present invention presses vacuum-load device in one, isolation knife 5 lower end is rotatably connected on upper bracket 6, isolation knife 5 pairs of power supplys input the effect of connection and the isolation played lower end, isolation knife 5 axle cylinder lever connecting rod 18, isolation knife 5 inputs pile crown 19 and is fixedly mounted on the first insulated column 4, first insulated column 4 is fixed on support 1, isolation knife 5 output is fixed on upper bracket 6 by the first conducting block 20, upper bracket 6 lower end connects vacuum interrupter 8 input, the electric arc buffer action that vacuum interrupter 8 produces when playing combined floodgate and separating brake, buffer action and energization action can be carried out when load, vacuum interrupter 8 output connects the second conducting block 21 on lower carriage 10, vacuum interrupter 8 lower end contact connects connecting rod 17 one end, described connecting rod 17 other end connects insulation pull bar 13, insulation pull bar 13 is the control for vacuum interrupter 8 Contact Breaking/Making Operations, described insulation pull bar 13 is fixed on support 1 lower end by adjustment screw 12, the distance that adjustment screw 12 mainly regulates vacuum interrupter 8 contact to combine, can avoid producing the vacuum extinction contact that cause excessive apart from the electric arc of excessive generation to burn and the adjustment carried out not in place, adjustment screw 12 is set with fairlead 11, fairlead 11 be operation knob close a floodgate and separating brake time can not offset the close arc chamber 8 of vacuum, described fairlead 11 connection for transmission part 22, the side fitting operation panel 7 of isolation knife 5 on described support 1, described guidance panel 7 is arranged isolation knife rim brake knob 14 and is used for controlling isolation knife 5 deciliters, vacuum interrupter combined floodgate knob 15, vacuum interrupter separating brake knob 16, install retainer 9 side by side outside described vacuum interrupter 8, retainer 9 mainly plays hold mode when vacuum interrupter 8 deciliters, avoids super distance to damage vacuum interrupter 8, described connecting rod 17 is L-type, the circular hole at its knuckle place is connected with one end of separating brake extension spring 3, the effect of quick acting switching-off is played in separating brake extension spring 3 when isolation knife 5 separating brake, reduce because separating brake brings the electric arc burning-point time, described separating brake extension spring 3 other end is fixed on upper bracket 6, described separating brake extension spring 3 is parallel with retainer 9, the middle position axis cylinder lever connecting rod 18 on lower side of described isolation knife 5.
The present invention presses vacuum-load device in one; by out-put supply connect isolation knife 5 introduce in voltage source, isolation knife 5 to be arranged on support 1 fixing, and for load when avoiding separating brake, to produce electric arc excessive; adopt separating brake extension spring 3 to accelerate the speed of separating brake, play the effect that protective separation cutter 5 contact damages.Be ensure that the position of pile crown in isolation knife 5 is accurate when isolation switch 5 separating brake, and safe distance adopt insulated column 4 to be fixed.Vacuum interrupter 8 is that the power supply inputted by isolation knife 5 connects, and make its conjunction by combined floodgate knob 15 and separating brake knob control 16 and divide, separation and the energization action of power supply mainly can be carried out when power source loads, vacuum interrupter 8 can cut off fast to electric arc, and retainer 9 plays overtravel and damages vacuum interrupter 8 when vacuum interrupter deciliter.Vacuum interrupter 8 out-put supply carries out conduction by lower carriage 10 and connects.Vacuum interrupter 8 close a floodgate and the work of separating brake knob time, overlap 11 contacts moving vacuum interrupter 8 by pull bar 13 heap that insulate again and be combined by close a floodgate knob 15 and driving member 22 connecting band action-oriented of vacuum interrupter 8 function realizing closing a floodgate.In like manner vacuum interrupter 8 separating brake knob 16 and driving member 2 connecting band action-oriented overlap 11 and pull the contact of vacuum interrupter 8 to be separated the function realizing separating brake by the pull bar 13 that insulate again.Combination the best between vacuum interrupter 8 contact adopts adjustment screw 12 to regulate.
Press vacuum-load device must first to close when closing operation isolation switch 5 and then the vacuum interrupter 8 that closes in the present invention, and during separating brake, first must separate vacuum interrupter 8, more separately isolation switch 5, otherwise easily arc burning causes isolation switch 5 to damage.
Structure of the present invention is simple, ingenious, reasonable; The present invention carries out linear quadratic control by vacuum interrupter and isolation knife, make power equipment in load conditions, the electric arc produced during divide-shut brake can be gone out electric arc breath rapidly by vacuum interrupter, avoid causing equipment fault, simultaneously when vacuum interrupter breaks down, easily vacuum interrupter is keeped in repair.
