Embodiment Construction

[0016] Now in conjunction with the accompanying drawings, the structure of the present invention will be further described. Such as Figure 1-Figure 5 As shown, the device includes spring seat 1, roller sleeve 2, fixed hanging spring shaft 3, closing spring 4, elastic cylindrical pin 5, buffer sleeve 6, energy storage crank arm 7, guide roller 8, guide plate 9, hexagonal locking The nut 10, the guide plate and the buffer sleeve are combined into a whole through elastic cylindrical pins. The closing springs at both ends of the guide plate are respectively limited to the spring seat, and the spring seat is respectively provided with a roller sleeve and a guide roller. The spring seat at the end of the roller sleeve, the guide plate and the fixed hanger The spring shaft is connected, and the spring seat and the guide plate at the end of the guide roller are connected with one end of the energy storage arm. One end swings as the center of rotation to realize telescoping. Simulta...

Abstract

The present invention relates to a spring operating mechanism closing spring residual energy absorption device and an operating principle thereof which are designed aiming at the technical problems that closing springs are poor in energy storage stability and is irregular in swing angle in the similar products to cause that the closing residual energy is difficult to be absorbed and the closing isdifficult to arrive at a normal position. Closing springs are arranged at the outer diameter of a closing spring seat of the device, and two ends of the closing spring seat are respectively connectedwith a fixed hanging spring shaft and an energy storage connecting lever. A guide plate and a buffer sleeve of the closing spring seat are combined through elastic cylindrical pins to form an integrated body, the closing springs at two ends of the guide plate are spaced at the spring seat, the spring seat is internally provided with a rolling sleeve and a guide roller, a spring seat at the rolling sleeve end and the guide plate are connected with the fixed hanging spring shaft, the spring seat at the guide roller end and the guide plate are connected with one end of the energy storage connecting lever, the guide plate at this end is provided with a buffer hole, the buffer sleeve is located at the guide plate close to one side of a tube sleeve, the closing springs take the other end of theenergy storage connecting lever as rotation centers to perform swing to achieve stretching.

Description

technical field [0001] The invention relates to electrical principles in the mechanical high-voltage switch industry, and is a residual energy absorbing device for a closing spring of a spring operating mechanism. Background technique [0002] The closing spring part of the spring operating mechanism is the key part for closing the high voltage AC vacuum circuit breaker. When the energy-stored closing spring releases energy to do work, part of the energy needs to make the circuit breaker close reliably, and another part of the energy needs to make the opening spring ready for energy storage before opening, so the closing spring components are designed to Whether it is reasonable or not plays an extremely important role in satisfying the mechanical characteristic parameters of the circuit breaker. At present, the design of the closing spring parts of the spring operating mechanism at home and abroad generally adopts two structural forms of extension spring and compression sp...
