Embodiment
Below in conjunction with description of drawings and embodiment the utility model is done further to describe in detail.
Referring to Fig. 1 to Fig. 4; A kind of outdoor high-voltage vacuum breaker of the utility model and the interlock of isolating switch; Comprise isolating switch main shaft 1 and circuit breaker main shaft 6; Offer matrix breach 15 on the end outer round surface of said interlocking rotating shaft 3 near isolating switch main shaft 1, corresponding matrix breach 15 is fixed with block 2 on the isolating switch main shaft 1, and the other end of interlocking rotating shaft 3 is fixed with connecting lever 14; The end of connecting lever 14 is pulled an end of 7 and is connected with shaking through connecting plate 16, shakes and pulls the end that 7 the other end is fixed on circuit breaker main shaft 6.
Said circuit breaker main shaft 6 pulls 7 through screw 13 with shaking, and is provided with packing ring 11 and bullet pad 12.
Side near matrix breach 15 in the said interlocking rotating shaft 3 is provided with plain cushion 5, and adds split pin 4.
Said shake pull 7 with connecting plate 16 between be connected through bearing pin 10, be equipped with on the bearing pin 10 to shake and pull split pin 8 and equalize pad 9 with shaking.
The bottom surface of said matrix breach 15 parallels with the central axis of interlocking rotating shaft 3, and the central axis of interlocking rotating shaft 3 and the central axis of isolating switch main shaft 1 parallel.
The axle center of said isolating switch main shaft 1 to the distance of block 2 ends greater than the axle center of isolating switch main shaft 1 distance, and less than the axle center of isolating switch main shaft 1 distance to matrix breach 15 bottom surfaces to interlocking rotating shaft 3 outer surfaces.
Referring to Fig. 1; The interlocking rotating shaft 3 on and offer matrix breach 15 on the end outer round surface near isolating switch main shaft 1; The other end of interlocking rotating shaft 3 is fixed with connecting lever 14, and the bottom surface of matrix breach 15 is the plane, and the central axis of this bottom surface and interlocking rotating shaft 3 parallels.Corresponding matrix breach 15 is fixed with block 2 on the isolating switch main shaft 1, and the outer end of block 2 etc. enough extend in the matrix breach 15, can play the effect of locking.The axle center of isolating switch main shaft 1 to the distance of block 2 ends greater than the axle center of isolating switch main shaft 1 distance, and less than the axle center of the opening of matrix breach 15 isolating switch main shaft 1 when the isolating switch main shaft 1 distance to matrix breach 15 bottom surfaces to interlocking rotating shaft 3 outer surfaces.Be provided with plain cushion 5 near a side of matrix breach 15 in the interlocking rotating shaft 3, and it is fixing to add split pin 4.Interlocking rotating shaft 3 is a multidiameter, and multidiameter partly gets in the bracket holes of underframe, makes interlocking rotating shaft 3 to rotate, and can not move axially.
