Detailed Description
In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.
The first embodiment is as follows: the utility model provides a novel three linkage double-closing spring mechanism of 220KV circuit breaker, as shown in the figure, including energy storage gear 1, with the pivot 2 of the coaxial rigid coupling of energy storage gear 1 to and set up two sets of energy storage mechanism in pivot 2, energy storage mechanism includes the energy storage turning arm 3 with the rigid coupling of pivot 2, rotate to connect the energy storage axle 4 at the position that energy storage turning arm 3 kept away from pivot 2, and keep away from the closing spring 5 of the 3 one end rigid couplings of energy storage turning arm with energy storage axle 4. Energy storage gear 1 meshes with the action wheel that sets up on the circuit breaker through motor drive, rotates through action wheel drive energy storage gear 1, and the central line of energy storage gear 1 and the central line coincidence of pivot 2 to drive pivot 2 when making energy storage gear 1 rotate and rotate. Energy storage connecting lever 3 is the structure of water droplet shape, the stub end and the 2 rigid couplings of pivot of energy storage connecting lever 3, the stub end of energy storage connecting lever 3 and the one end coupling of energy storage axle 4, make energy storage axle 4 can take place the rotation for energy storage connecting lever 3, the other end rigid coupling closing spring 5 of energy storage axle 4, through pivot 2, energy storage connecting lever 3, and energy storage axle 4 has constituted slider-crank mechanism, thereby change into the straight reciprocating motion of energy storage axle 4 through the rotation with pivot 2, thereby reach the effect of compression or tensile closing spring 5, realize the purpose of closing spring 5 energy storage.
The two groups of energy storage mechanisms are symmetrically arranged on two sides of the circuit breaker. The operation stress of the closing energy storage of the circuit breaker is more balanced by symmetrically arranging the circuit breaker on two sides.
The closing spring 5 is in a free state, the energy storage shaft 4 is fixedly connected with the upper end of the closing spring 5, and the hinged point of the energy storage shaft 4 and the energy storage connecting lever 3 is positioned right above the rotating shaft 2. When the pin joint of energy storage axle 4 and energy storage connecting lever 3 rotated to pivot 2 directly over, energy storage connecting lever 3 was in the highest position, and pivot 2 continues to rotate and will drive energy storage connecting lever 3 and the pin joint downstream of energy storage axle 4 to drive energy storage axle 4 downstream, realize closing spring 5's compression through energy storage axle 4, thereby realize the energy storage through compression closing spring 5.
The closing springs 5 are all arranged in the cylinder, and a gap of 1mm-3mm exists between the closing springs 5 and the outer diameter and the inner diameter of the cylinder. The position of the closing spring 5 is limited through the cylinder, so that the closing spring 5 is prevented from being bent or biased in position when being compressed, and the closing spring 5 is compressed along the correct direction. The energy storage shaft 4 is fixedly connected with the axis of the closing spring 5, so that the stress of the middle position of the closing spring 5 is balanced, and the stability of the closing spring 5 in deformation is improved.
Example two: the difference with the first embodiment is that the closing spring 5 is in a free state, the energy storage shaft 4 is fixedly connected with the upper end of the closing spring 5, and the hinge point of the energy storage shaft 4 and the energy storage connecting lever 3 is positioned right below the rotating shaft 2. When the pin joint of energy storage axle 4 and energy storage connecting lever 3 rotated to pivot 2 under, energy storage connecting lever 3 was in the lowest position, and pivot 2 continues to rotate and will drive energy storage connecting lever 3 and the pin joint rebound of energy storage axle 4 to drive energy storage axle 4 rebound, realize closing spring 5's extension through energy storage axle 4, thereby realize the energy storage through tensile closing spring 5.
