Description

Circuit breaker oil cup impact test mechanism

Technical Field

The invention belongs to a testing device for an oil cup accessory of a circuit breaker in the field of production and manufacturing of high-voltage electric appliances.

Background

In the field of high-voltage switch manufacturing, a vacuum circuit breaker is generally provided with a tripping buffer device, which is generally called an oil buffer or an oil cup, in the aspects of an actual production process and an accessory test, a universal test mode and a universal test device are not available all the time, oil cup tests in most assembly environments are lacked, or experience judgment and simple tests are mainly used, and the judgment difference can cause fluctuation and uncertainty of mechanical parameters and service life of the whole circuit breaker.

The invention relates to an energy storage triggering impact mechanical device of an oil cup testing mechanism, which is used for testing an oil cup in a simulation use state, so that the performance range of the oil cup is judged, the performance stability of the whole breaker is further ensured, and the service life of the breaker is prolonged.

Disclosure of Invention

Name: a circuit breaker oil cup impact test mechanism.

Brief introduction: the device design includes core parts such as a static groove drum, a dynamic groove drum, an impact hammer, an energy storage spring, a reset spring, a pin and the like, and is matched with devices such as a mounting plate, a support, a speed reducer, a motor and the like, so that the simulation effect of the test process is realized, and the data quantization is facilitated.

Drawings

The structure is as follows:

FIG. 1: key parts assembly drawing

FIG. 2: structural composition diagram

The working process principle is as follows:

under the initial position, the motor rotates forwards, the output shaft of the speed reducer drives the gear rack to move, the movable grooved drum is pressed downwards, the energy storage spring in the grooved drum is compressed to store energy, and the device enters an energy storage state.

FIG. 3 energy storage State

And the upper end inclined plane of the movable groove drum groove touches the impact hammer pin, the pin and the impact hammer rotate together for an angle and slide out of the fixed groove drum positioning step, and slide down along the fixed groove drum groove under the action of the energy storage spring, so that the impact action of the impact hammer on the detection piece instantly is realized.

FIG. 4 Release State

The innovation points are as follows:

the main innovation point of the circuit breaker oil cup impact test mechanism is that an energy storage triggering mechanical device capable of achieving the detection function is provided.

The device ingeniously designs core parts such as a static groove barrel, a dynamic groove barrel, an impact hammer, an energy storage spring, a reset spring, a pin and the like in a limited space, and is matched with devices such as a mounting plate, a support, a speed reducer, a motor and the like, so that the instantaneous impact function in a simulation state required by the test process is realized, and the structure and the action mode are convenient for further combining with measurement and operation parts, so that the automation and the digitization of the whole set of device are realized.
