Embodiment Construction

[0023] Embodiment of the circuit breaker spring operating mechanism:

[0024] The structural diagram of the circuit breaker spring operating mechanism is as follows: Figure 1~5 As shown, the circuit breaker spring operating mechanism includes a flexible clutch. The flexible clutch includes a retaining ring 1, a ball bearing 3, a wrap spring 4 and a friction hub 5. The flexible clutch is connected to the shaft 6 through a gear 2.

[0025] The working principle of the flexible clutch is as follows: Figure 3~5 As shown, when the spring operating mechanism of the circuit breaker is in the state of energy storage, the energy storage motor is energized and rotates counterclockwise, and the two-stage gear pair drives gear 2 to rotate counterclockwise. At the moment when the gear 2 starts to rotate, because one end of the wrap spring 4 is fixedly connected to the gear 2, the gear 2 and the wrap spring 4 are connected as a whole, and the other end is pressed on the outer circumferen...

Abstract

The invention relates to the technical field of high-voltage switches, in particular to a flexible clutch and a circuit breaker spring operating mechanism using the same, so as to solve the problem of high requirement on material performance caused by rigid extrusion and torsion in the prior art. In order to solve the technical problem, one end of a holding spring is fixed on a driving gear, the other end sleeves a driven friction wheel hub, the holding spring contracts in a diameter reducing manner to achieve joint of a driving part and a driven part of the clutch when the driving gear rotates relative to the driven friction wheel hub positively. The flexible clutch avoids rigid extrusion by adopting the spring serving as a medium for transferring force and torque, through the method, the requirement on material performance is reduced, the number of components in the clutch is reduced, the clutch is convenient to disassemble and assemble, the product complete set forming time is shortened, and the research and development test cycle and component cost of products are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of high-voltage switches, in particular to a flexible clutch and a circuit breaker spring operating mechanism using the clutch. Background technique [0002] Because the spring operating mechanism uses a conventional motor to drive the spring to store energy, and then uses the energy-stored spring as a power element to realize the closing action of the circuit breaker, it avoids the use of high-power DC power supply, greatly reduces the closing current, and improves the performance of the circuit breaker. The safety performance of circuit breaker opening and closing, so the spring operating mechanism is widely used in medium and high voltage circuit breakers. [0003] In the spring closing process, in order to prevent the motor from burning at high speed under passive conditions, a clutch device is usually installed in the spring operating mechanism. The main function of the clutch device is to transmit spe...
