Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of silicon rubber insulation pull bar for primary cut-out of the present utility model.
In figure, 1. epoxy vacuum impregnation rod, 2. falope, 3. steel screw bushing, 4. connection inserting part, 5. connecting rod, 6. disc spring, 7. disk compressing tablet, 8. nut, 9. screw rod, 10. fixed head, 11. hex boltss.
Embodiment
Below in conjunction with embodiment, the utility model is described in detail.
The structure of a kind of silicon rubber insulation pull bar for primary cut-out that the utility model provides as shown in Figure 1, comprise epoxy vacuum impregnation rod 1, the outer surface of epoxy vacuum impregnation rod 1 is provided with the falope 2 of cluster parachute shape, the two ends of epoxy vacuum impregnation rod 1 are respectively arranged with steel screw bushing 3 and connection inserting part 4.
Connection inserting part 4 comprises the connecting rod 5 be arranged in connection inserting part 4 hollow cavity, connecting rod 5 is arranged along the length of epoxy vacuum impregnation rod 1 to direction, connecting rod 5 is provided with disc spring 6, the other end of connecting rod is connected with disk compressing tablet 7, the another side of disk compressing tablet 7 is connected with nut 8, nut 8 is provided with screw rod 9, connecting rod 5, disk compressing tablet 7 and screw rod 9 can one-body moldedly manufacture.
Be provided with fixed head 10 between nut 8 and screw rod 9, fixed head 10 is fixed on the end face of connection inserting part 4 by hex bolts 11.
During use, steel screw bushing 3 is connected by screw rod with the operating mechanism of primary cut-out, then the screw rod 8 on connection inserting part 4 is carried out being threaded can operate with the moved end of vacuum interrupter.
Because epoxy vacuum impregnation rod 1 has good insulation preformance, mechanical strength is high and shock resistance is strong feature, therefore a kind of inside of the silicon rubber insulation pull bar for primary cut-out of the present utility model adopts epoxy vacuum impregnation rod 1, and owing to needing to select the good material of hydrophobicity to carry out wrapping up improving its hydrophobicity performance in outside, therefore at the outer wrap falope 2 of epoxy vacuum impregnation rod 1, falope 2 is made cluster parachute shape and then greatly strengthen the outer creep distance of its insulation, make the performance of whole insulated tension pole more reliable and stable.
By the way, a kind of silicon rubber insulation pull bar for primary cut-out of the present utility model solves the intensity difference of existing insulated tension pole existence and the shortcoming of insulation property difference, a kind of inside of the silicon rubber insulation pull bar for primary cut-out of the present utility model adopts epoxy vacuum impregnation rod to make, and its good insulation preformance, mechanical strength are high and shock resistance is strong, and the falope of outsourcing cluster parachute shape make its hydrophobicity good, enhance the outer creep distance of insulation, thus make insulation property more reliable and more stable.
