The ejector rod of the release abuts against the dynamometer sensor after being ejected out, so that the ejection force of the release is measured, and the detection device is more convenient to detect.

Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, and particularly relates to a tripping force detection device for a release. Background Art

[0002] The existing leakage circuit breaker includes a housing, a release, an operating mechanism and a contact mechanism. When a leakage fault occurs, the ejector rod of the release will eject, driving the tripping latch of the operating mechanism to unlock, so as to drive the moving contact of the contact mechanism to separate from the static contact and disconnect. Therefore, the magnitude of the ejecting force of the ejector rod of the release is very important. However, the existing test of the tripping force of the release is relatively cumbersome and inconvenient to use. Content of the Utility Model

[0003] Therefore, the technical problem to be solved by the utility model is to overcome the defect that it is inconvenient to detect the magnitude of the tripping force of the release in the prior art, so as to provide a tripping force detection device for a release that is convenient to detect.

[0004] To this end, the utility model provides a tripping force detection device for a release, which includes a bracket fixture, a fixture driving mechanism and a dynamometer. The bracket includes a top plate and L-shaped support plates respectively arranged on both sides of the top plate; a fixture, having two vertically arranged positioning columns on its top, and the positioning columns are positioned and connected with two positioning holes of the release; a fixture driving mechanism, connected with the fixture, and adapted to drive the fixture to move along the front-back direction of the bracket; a dynamometer, adapted to move along the left-right direction of the bracket under the drive of the dynamometer driving mechanism, so that a sensor at one end of the dynamometer is close to the ejector rod of the release.

[0005] Two wire clips are arranged on the bracket and are respectively clamped and connected with the two lead wires at both ends of the release.

[0006] Both the fixture driving mechanism and the dynamometer driving mechanism are ball screw mechanisms.

[0007] One end of the ball screw mechanism of the fixture driving mechanism is provided with a first adjustment knob, and one end of the ball screw mechanism of the dynamometer driving mechanism is provided with a second adjustment knob, and the second adjustment knob is arranged at one end of the dynamometer far away from the fixture.

[0008] Pads are arranged at each corner of the bottom of the L-shaped support plate.

[0009] The technical solution of the utility model has the following advantages:

[0010] 1. The utility model provides a release ejection force detection device, including a bracket, a fixture, a fixture driving mechanism, a dynamometer and a dynamometer driving mechanism. During the test, the release is first mounted on the fixture, and the two positioning posts on the fixture are positioned correspondingly to the positioning holes of the release. Then, the fixture is driven by the fixture driving mechanism to move along the front and rear directions of the bracket, so that the ejector rod of the release and the sensor of the dynamometer are arranged relatively. Then, the sensor of the dynamometer is driven by the dynamometer driving mechanism to move to a position close to the ejector rod of the release. Finally, the release is energized, and the ejector rod of the release is pushed out and abuts against the dynamometer sensor, thereby measuring the ejection force of the release. The above detection device is more convenient for detection.

[0011] 2. The releaser top output force detection device provided by the utility model has two wire clamps on the bracket which are respectively clamped and connected with the two ends of the lead wires of the releaser, and the other end of the wire clamp is connected with the power supply end, which is more convenient for clamping the wires.

[0022] Example

[0023] This embodiment provides a release push-out force detection device, such as Figure 1 As shown, it includes a bracket 1, a clamp 4, a clamp driving mechanism 8 and a dynamometer 9.

[0024] Bracket 1, such as Figure 4 As shown, it includes a top plate 2, and L-shaped support plates 3 arranged on both sides of the top plate 2, and pads 15 are provided at each corner of the bottom of the L-shaped support plate 3. The bracket 1 is provided with two wire clamps (not shown in the figure) respectively clamped and connected to the two ends of the lead wires of the release 6, and the other end of the wire clamp is used to connect to the power supply.

[0025] Fixture 4, such as Figure 2 and Figure 3As shown, it has two vertically arranged positioning columns 5 arranged on the top thereof, and the positioning columns 5 are positioned and connected with two positioning holes 7 of the release 6. A clamp driving mechanism 8 is connected to the clamp 4 and is suitable for driving the clamp 4 to move along the front-rear direction of the bracket 1.

[0026] The dynamometer 9 is suitable for moving along the left and right direction of the bracket 1 under the drive of the dynamometer driving mechanism 10, so that the sensor 11 at one end of the dynamometer 9 is arranged close to the top rod 12 of the release 6. The clamp driving mechanism 8 and the dynamometer driving mechanism 10 are both ball screw mechanisms. It should be noted that the ball screw mechanism is an existing mature technology, so its specific structure and working principle are not described in detail. A first adjusting button 13 is provided at one end of the ball screw mechanism of the clamp driving mechanism 8, and a second adjusting button 14 is provided at one end of the ball screw mechanism of the dynamometer driving mechanism 10. The second adjusting button 14 is arranged at the end of the dynamometer 9 away from the clamp 4. As a convertible embodiment, the clamp driving mechanism and the dynamometer driving mechanism can be cylinder driven.

During testing, the release 6 is first mounted on the fixture 4, and the two positioning columns 5 on the fixture 4 are positioned correspondingly to the positioning holes 7 of the release 6. Then, the fixture driving mechanism 8 drives the fixture 4 to move along the front-to-back direction of the bracket 1, so that the ejector rod 12 of the release 6 and the sensor 11 of the dynamometer 9 are arranged relatively. Then, the dynamometer driving mechanism 10 drives the sensor 11 of the dynamometer 9 to move to a position close to the ejector rod 12 of the release 6. Finally, the release 6 is energized, and the ejector rod 12 of the release 6 is pushed out and abuts against the dynamometer sensor 11, thereby measuring the ejection force of the release. The above detection device is more convenient for detection.
