Detailed description of the invention
Embodiment one: this is the utility model embodiment that an external force is electromagnet, referring to Fig. 1-Fig. 4.
The utlity model has being as can be seen from Figure 1 subject to of power supply terminal 2, A/B/C three-phase of insulator 1, A/B/C three-phaseElectric terminal 3, action bars 4, action bars service aisle 5. The wherein electrified terminal of the power supply terminal 2 of A/B/C three-phase, A/B/C three-phase3, action bars service aisle 5 is arranged in insulator 1, and action bars 4 is in action bars service aisle 5, and action bars is at the work of external forceMove along its service aisle with lower. The power supply terminal 2 of A/B/C three-phase, the electrified terminal 3 of A/B/C three-phase all adopt elastic force terminal,Elastic force contact 21 on power supply terminal 2 contacts with action bars 4 all the time as can be seen from Figure 2, and electrified terminal 3 is tied with power supply terminal 2Structure is identical. Can find out that in conjunction with Fig. 3 action bars 4 is formed by insulating segment 41, conductive segment 42 interphase distributions. Power supply terminal 2 and be subject to electricityTerminal 3 contacts with action bars 4 all the time. What the external force of action bars adopted in the present embodiment is electromagnet 7, when electromagnet 7 leads toWhen electricity work, the power supply terminal 2 of state A/B/C three-phase all contacts with the insulating segment 41 of action bars as shown in Figure 1, and A/B/C tri-3 of the electrified terminals of phase contact with the conductive segment 42 of action bars, make electrified terminal in electroless state, now the utility model dressPut in electricity and cut off state. Under this state, can make load system keep in repair, especially straight with the utility model deviceThe high voltage load switch connecing in succession can keep in repair. In the time that electromagnet power-off discharges, promote action bars toward reach, as Fig. 4 instituteShow, the power supply terminal 2 of A/B/C three-phase all contacts with the conductive segment 42 of action bars with electrified terminal 3, makes the electricity that is subject to of A/B/C three-phaseTerminal all electric, now the utility model device is in status of electrically connecting. Can make load in normal operating condition. For convenientPower supply terminal 2, electrified terminal 3 and action bars 4 are installed, and insulator is done two from 5 punishment of action bars service aisle, at power supply terminal2, electrified terminal 3 and action bars 4 are tightened to one by some bolts 6 by insulator after being all in place.
Embodiment two: this is the utility model embodiment that an external force is gear mechanism, referring to Fig. 5-Fig. 7.
What in present embodiment, action bars 4 adopted as can be seen from Figure 5 is screw rod, and this screw rod is still according to one section of insulating segmentThe regular arrangement of one section of conductive segment, can find out that in conjunction with Fig. 6 power supply terminal 2 passes through spiral shell with electrified terminal 3 with contacting of action bars 4Line connects to be realized, and what external force adopted is motor 8, and this motor drives action bars 4 spirals to move by gear mechanism 9, shown in Fig. 5State is that the utility model device cuts off state in electricity, now power supply terminal 2 contact with insulating segment 41 and electrified terminal 3 with lead42 contacts of electricity section. If when motor 8 drives action bars 4 to move forward, power supply terminal and electrified terminal will be in same and conducting endThe state of son contact, now electrified terminal obtains electricly, and the utility model device is in status of electrically connecting, as shown in Figure 7.
