Abstract
A spring-assisted switching operation mechanism for an isolation switch belongs to the field of a high-voltage switch operating mechanism. The spring-assisted switching operation mechanism comprises a pedestal, fulcrum bearings, a gear case, a power-assisted mechanism and three switching crank arms. The central section of the pedestal is provided with the gear case; each of two ends of the pedestal is provided a fulcrum bearing; each of two ends of the gear case along the length direction is provided with an output shaft; the output terminals of the output shafts at two ends of the gear case are respectively rotatably connected to the fulcrum bearings at the corresponding ends; the gear case is also provided with a driving shaft for driving the output shafts at two ends to rotate; and the three switching crank arms are uniformly arranged on the output shafts at two ends of the gear case. When the spring-assisted switching operation mechanism runs, energy is rapidly released through an auxiliary spring, the rotating shafts are driven to rotate rapidly, switching operation is completed, and operation power of the switch is reduced.
Description
Technical field
The utility model belongs to operation mechanism for high voltage switch field, is specially a kind of spring resistance isolating switch opening/closing operation mechanism.
Background technology
What isolator operating mechanism of the prior art was equipped with substantially is manual-operating mechanism, and the operation of divide-shut brake must complete by manpower, and the complex structure of manual-operating mechanism, the power that consumes during operation is larger, and divide-shut brake is very inconvenient; In addition existing isolating switch minute/during closing position, isolating switch does not arrange the switch that reliable self-locking mechanism prevents isolating switch and is shifted, security performance is poor.
Utility model content
The purpose of this utility model is to provide that a kind of operation is light, labour-saving spring assist isolating switch opening/closing operation mechanism.
The technical scheme that realizes above-mentioned purpose is: a kind of spring resistance isolating switch opening/closing operation mechanism, it is characterized in that: comprise base, supporting base, gear box, servomechanism and three divide-shut brake connecting levers, the middle part of base is provided with gear box, the two ends of base are respectively arranged with supporting base, described gear box is respectively arranged with output shaft along the two ends of base length direction, the output of gear box two ends output shaft is rotatably connected respectively on the supporting base of respective ends, is also provided with the driving shaft that drives two ends output shaft rotation on described gear box, described three divide-shut brake connecting levers are evenly arranged on the output shaft at gear box two ends, described servomechanism comprises a left side, right fixed head, power assistant spring drive rod, spring and power-assisted connecting lever, a described left side, right fixed head is vertically fixed on base, a described left side, between the front and back side of right fixed head upper end, be connected with rotationally respectively spacer pin, one end of described power-assisted connecting lever is fixedly connected on a left side, on gearbox output shaft between right fixed head, the other end of power-assisted connecting lever is provided with rotating shaft, a described left side, on right fixed head, be symmetrically arranged with respectively arc chute, on described power-assisted connecting lever, the two ends of rotating shaft are placed through respectively a left side, in the arc chute of right fixed head, one end of described power assistant spring drive rod is connected with one end that power-assisted connecting lever is provided with rotating shaft, the other end of power assistant spring drive rod is connected to a left side, on the spacer pin of front side, right fixed head upper end, on power assistant spring drive rod, placed spring.
When the utility model needs breaking-closing operating, the driving shaft of driving gearbox rotation, the output shaft rotation at driven gear case two ends drives three the divide-shut brake connecting levers and the power-assisted connecting lever that are arranged on the output shaft of gear box two ends to rotate simultaneously.Power-assisted connecting lever rotates, and drives power assistant spring drive rod to move together, and power assistant spring drive rod is in the process of motion, can compress power assistant spring, when power assistant spring drive rod moves to critical localisation, the decrement of power assistant spring is maximum, and now the elastic force of spring is maximum, when power assistant spring drive rod motion postcritical, power assistant spring drive rod is not just at Compress Spring, and the elastic force of spring can discharge, and drives power assistant spring drive rod rapid movement, drive rotating shaft quick rotation, complete minute/closing operation.
The utility model, in when operation, can be driven fast and be released energy by power assistant spring, and drive shaft quick rotation completes minute/closing operation the operating work of reduction switch.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mode specifically
As shown in Figure 1, the utility model comprises base 1, supporting base 2, gear box 3, servomechanism 4 and three divide-shut brake connecting levers 5, the middle part of base 1 is provided with gear box 3, the two ends of base 1 are respectively arranged with supporting base 2, gear box 3 is respectively arranged with output shaft 6 along the two ends of base 1 length direction, the output of gear box 3 two ends output shafts 6 is rotatably connected respectively on the supporting base 2 of respective ends, on gear box 3, being also provided with 7, three the divide-shut brake connecting levers 5 of driving shaft that drive two ends output shaft 6 to rotate is evenly arranged on the output shaft 6 at gear box 3 two ends.
