Abstract
The utility model discloses a new structure of a transmission shaft of a high voltage circuit breaker mechanism, which leads a whole main shaft of the transmission shaft of the existing high voltage circuit breaker mechanism to be designed into two parts including an upper shaft and a lower shaft; the upper shaft is provided with a spring; the upper shaft is connected with the lower shaft by a pin shaft; the pin shaft is internally sheathed with a damping spring; and a cotter pin is adopted at the upper end of the pin shaft for blocking out. Therefore, the mass of the transmission shaft is lightened; and as the damping spring is added between the upper shaft and the lower shaft, the just-open speed of a movable contact and a fixed contact can be greatly improved, and the cut-off property of the circuit breaker is guaranteed.
Description
Technical field:
The utility model relates to a kind of high-voltage breaker mechanism power transmission shaft new construction, belongs to High-Voltage Electrical Appliances manufacturing technology field.
Background technology:
Circuit breaker is as a kind of online protection component, and it will have by cramp 1, support 2, spring 3, main shaft 4, coil 5, insulator 6, vacuum interrupter 7, moving bar 8, disk 9, rivet 10, guide holder 11, pin 12, riser 13, tripping 14 and is constituted.The upper end of its main shaft 4 is connected with riser 13 by screw thread, the lower end is connected with insulator 6 by screw thread, disk 9 is connected on the main shaft 4 by rivet, tripping 14 is fixed on the riser 13, pin 12 passes the waist hole and riser 13 holes of guide holder 11, riser 13 can be in the groove of guide holder 11 slippage up and down, guide holder 11 is fixed on the support 2, the moving bar 8 of vacuum interrupter 7 is connected (the turnover line busbar that has omitted vacuum interrupter 7 among the figure) by screw thread with insulator 6.Coil 5 when electric, driving main shaft 4 up moves, main shaft 4 up moves by the moving bar 8 that insulator 6 drives vacuum interrupters, and dynamic and static contact is separated; The buckle side of crossing cramp 1 is up moved in tripping 14 on the riser 13; After coil 5 dead electricity, under spring 3 effects, make tripping 14 and cramp 1 snap close (as the figure position).During combined floodgate, drive cramp 1 and rotate counterclockwise around its center, tripping 14 is threaded off, under spring 3 effects, main shaft 4 moves down, and moving bar 8 also moves down dynamic and static contact closure.
Though this breaker mechanism main shaft is simple in structure, make easily, the riser 13 because main shaft 4 is ined succession, when making breaker open operation, the quality of mechanism kinematic spare is very big, has influenced the movement velocity of the firm timesharing of dynamic and static contact greatly.
Summary of the invention:
In view of the problem of above-mentioned existence, the purpose of this utility model provides a kind of simple in structure, make, simple installation, and the high-voltage breaker mechanism power transmission shaft new construction of movement parts quality can effectively alleviate mechanism's separating brake the time.
A kind of high-voltage breaker mechanism power transmission shaft new construction described in the utility model is the improvement to existing high-voltage breaker mechanism power transmission shaft, it is designed to axle and lower shaft two parts with the integral one-piece mainshaft of existing high-voltage breaker mechanism power transmission shaft, on last axle, be provided with spring; Adopt bearing pin to connect between the last lower shaft, in bearing pin, be set with damping spring, the split pin screens is adopted in the bearing pin upper end; Like this, not only alleviated the quality of power transmission shaft effectively, and, therefore improved the speed of the firm timesharing of dynamic and static contact greatly, thereby guaranteed the break performance of circuit breaker owing between last lower shaft connects, added damping spring.

Embodiment:
A kind of high-voltage breaker mechanism power transmission shaft new construction described in the utility model is the improvement to existing high-voltage breaker mechanism power transmission shaft, it is designed to axle 19 and lower shaft 15 two parts with the integral one-piece mainshaft 4 of existing high-voltage breaker mechanism power transmission shaft, on last axle 19, be provided with spring 20; Adopt bearing pin 16 to connect between the last lower shaft, in bearing pin 16, be set with damping spring 17; Split pin 18 screens are adopted in bearing pin 16 upper ends, and assurance bearing pin 16 can not deviate from from last axle 19.In this structure, the firm timesharing of the dynamic and static contact of circuit breaker, its moving component is moving bar 8, insulator 6, lower shaft 15, bearing pin 16 and cottering 18 thereof, remain static because of inertia and go up axle 19, riser 13 etc., only after vacuum interrupter 7 dynamic and static contacts were opened to certain distance (can not thump and wear), last axle 19, riser 13 just can participate in motion.The utility model is owing to be designed to axle and lower shaft two parts with traditional primary cut-out integral type power transmission shaft, and between connecting, last lower shaft added damping spring, like this, not only alleviated the quality of power transmission shaft effectively, and improved the speed of the firm timesharing of dynamic and static contact greatly, thereby guaranteed the break performance of circuit breaker.
