Summary of the invention
Goal of the invention of the present invention is to provide a kind of outdoor high-voltage locking isolating switch on pole that can effectively avoid the misoperation operation to carry out switch motion.Outdoor high-voltage locking isolating switch on pole technical scheme provided by the invention, its major technique content is: a kind of outdoor high-voltage locking isolating switch on pole, by base, fixedly be assembled in two supporting insulators of base and cooperate the operator plate that connects to constitute with the switch fixed contact parts switch on two supporting insulator tops, one end and the inlet wire side fixed contact parts of operator plate are hinged, operator plate hinged end is provided with anti-misoperation mechanism, this mechanism comprises the hinged lock fork stirred that is arranged at the operator plate, stirring lock fork outer end is handlebar, the below of handlebar is provided with stirs lock fork spacer pin, and the struck side of stirring the lock fork is that the lock-bit plate lock with being fixed in described inlet wire side fixed contact parts that is V-shape is opened, the operator plate that locking cooperates closes a floodgate, and lock refers to and the plate separating brake lock of operating refers to; Described lock-bit plate with stir that the lock fork corresponding lock in stirring refers to realize to lock out, the position that cooperates of locking is provided with operator plate combined floodgate lock-bit groove and operator plate separating brake lock-bit groove; Lock-bit spring one end hang on the pin that is provided with on the described lock-bit plate, the other end hang on and stirs the lock fork jointed shaft outside and refer to and between the separating brake lock refers at described combined floodgate lock.
Outdoor high-voltage locking isolating switch on pole technical scheme disclosed by the invention, wherein the anti-misoperation mechanism of She Zhiing has overcome the potential safety hazard of existing product completely, realized that the operator plate can not move with misoperation in combined floodgate or gate-dividing state, thereby guaranteed reliability and the fail safe of product at distribution line.
Embodiment
Outdoor high-voltage locking isolating switch on pole of the present invention, its concrete enforcement structure as shown in drawings, it is by base 1, fixedly be assembled in two supporting insulators 2 of base 1 and cooperate the operator plate 5 that connects to constitute with the switch fixed contact parts switch on two supporting insulators, 2 tops, operator plate 5 one ends and inlet wire side fixed contact parts 3 are hinged, and other end moving contact part cooperates with outlet side fixed contact parts 4 elastic switchs.As shown in the figure, the hinged side of operator plate of this outdoor high-voltage locking isolating switch on pole, also be that inlet wire side in the present embodiment is provided with anti-misoperation mechanism, this anti-misoperation mechanism includes the lock of stirring that is articulated in operator plate 5 and pitches 6, this outer end of stirring lock fork 6 is provided with handlebar, make clubs do for ease of gram, this handlebar is provided with operation ring 60, the inboard of stirring lock fork 6 be provided with the operator plate close a floodgate lock refer to 61 and operator plate separating brake lock refer to 62, the operator plate close a floodgate lock refer to 61 and operator plate separating brake lock refer to that 62 are the V-shape setting; The described lock fork 6 stirred cooperates with the lock-bit plate 7 that is fixed in inlet wire side fixed contact, the locking of realizing operator plate closing position and sub-gate position with lock ON operation.Lock-bit plate 7 and two locks of stirring lock fork 6 refer to match and are provided with operator plate combined floodgate lock-bit groove and operator plate separating brake lock-bit groove, in this present embodiment, operator plate separating brake lock-bit groove 72 is opened in lock-bit plate 7 inboard drift angle upside edge places, and operator plate combined floodgate lock-bit groove 71 is opened in the inboard drift angle lower lip place of lock-bit plate 7; Simultaneously cooperate lock to refer to by lock-bit spring 8 and the lock-bit groove between lock open or locking states, these lock-bit spring 8 one ends hang on stirs lock fork jointed shaft 66 outsides, on the pin that is provided with between two locks refer to, in the present embodiment, because lock-bit plate 7 and stir lock fork 6 and all be arranged in the parallel splint of operator plate, for ease of assembling, having the extension reed 80 that hangs lock-bit spring pin fixedly is assemblied in and stirs on the lock fork jointed shaft 66, another of lock-bit spring 8 hangs pin and is arranged on the lock-bit plate 7, in the present embodiment, be similarly the package assembly that does not as far as possible influence the fixed contact parts, be fixed with one by lock-bit plate set bolt and hang reed 81, this extension reed 81 is provided with the pin 35 that hangs the lock-bit spring other end.Too rotate to 5 inboards of operator plate for avoiding stirring lock fork 6, operator plate 5 is provided with stirs lock fork spacer pin 30, and to shown in Figure 4, the setting of this spacer pin 30 can only be rotated by operating space the handlebar of stirring lock fork 6 above this spacer pin as Fig. 2.
The course of work of this outdoor high-voltage locking isolating switch on pole is: 1, operator plate 5 is in "on" position, as scheme shown in the institute 2, this moment is under the pulling of lock-bit spring 8, the operator plate of stirring lock fork 6 closes a floodgate to lock and refers to that 61 fall in the operator plate combined floodgate lock-bit groove 71 of lock-bit 7, as the control loops 60 of using the power pulling identical to stir lock fork 6 with the plate separating brake direction of operating, because of its lock refers to locking action with the lock-bit groove, the operator plate can't be rotated by separating brake, i.e. locking operator plate closing position, unless stir the control loops 60 that lock is pitched with counterclockwise opposite direction power pulling, the operator plate is closed a floodgate lock and refer to that 61 break away from the restriction of operator plate combined floodgate lock-bit grooves 71, and in rotation, make lock-bit spring 8 on pin cross the maximum tension position, under the spacing acting in conjunction of lock-bit spring 8 and spacer pin 30, make the lock of stirring lock fork 6 refer to break away from fully the lock-bit groove of lock-bit plate 7, as shown in Figure 3, become lock to open state, just can carry out the sub-switching operation of this high voltage isolator this moment; 2, referring to Fig. 3, when operator plate 5 arrives the separating brake extreme position, when it is stirred lock fork 6 and keeps original state to turn to separating brake limit position with operator plate 5, the operator plate separating brake lock of stirring lock fork 6 refers to that 62 also slip in the operator plate separating brake lock-bit groove 72 of lock-bit plate 7 immediately, as shown in Figure 4, under the acting in conjunction of spacer pin 30 and lock-bit spring 8, the separating brake position of locking operator plate 5, under this locking states, misuse and the operator plate equidirectional active force pulling control loops 60 of closing a floodgate, can't drive operator plate 5 feed motions, unless rotate with clockwise direction power and to stir lock fork 6, make its operator plate separating brake lock refer to the 62 operator plate separating brake lock-bit grooves 72 of lock-bit plate 7 that slip away, and turn to position as shown in Figure 5, the lock of promptly stirring lock fork 6 refers to break away from fully the lock-bit groove of lock-bit plate 7, become lock and open state, at this moment, carry out the closing operation of operator plate 5 again, the operator plate of then stirring lock fork 6 closes a floodgate to lock and refers to slip into once more in the operator plate combined floodgate lock-bit groove 71 of lock-bit plate 7, is combined floodgate locking states as shown in Figure 2.
Show that from above operating process technical solution of the present invention can effectively be avoided operational motion, thereby improved its processing safety and reliability.
