Description
Technical Field
[0001] The present application relates to the field of trip unit detection equipment, and in particular to a trip unit testing device. Background Art
[0002] A trip unit is a device mechanically connected to a circuit breaker, releasing the holding mechanism and automatically opening the circuit breaker. If there's a leakage in the energized circuit or an electric shock, the trip unit quickly cuts off the power supply, providing protection against electric shock and leakage. After the trip unit is manufactured, it undergoes functional testing to assess its quality.
[0003] The relevant production quality tests of the trip unit include power-on testing and mechanical testing. The power-on testing requires connecting the trip unit to a power source and energizing the trip unit to check whether the T-bar on the trip unit can move. The mechanical testing requires moving the T-bar to determine whether the rotation and reset of the T-bar are normal.
[0004] The above-mentioned related technical solutions have the following defects: when the size of the trip unit is small, it takes a long time to install the power supply on the trip unit and toggle the T-bar, which reduces the testing efficiency. Utility Model Content
[0005] In order to improve the efficiency of testing the production quality of a trip unit, the present application provides a trip unit testing device.
[0006] The present application provides a release test device that adopts the following technical solution:
[0007] A trip unit testing device includes a detection frame, a power supply mechanism and an action mechanism. The detection frame includes a horizontal frame and a vertical frame. The horizontal frame and the vertical frame are perpendicular to each other and are connected to each other. The power supply mechanism is installed on the vertical frame. The horizontal frame is used to place the trip unit to be tested. The power supply mechanism is used to slide back and forth and is electrically connected to the trip unit. The action mechanism includes a second power member. The second power member is installed on the vertical frame. The second power member is used to extend and retract and toggle a T-bar.
[0008] By adopting the above technical solution, a power supply mechanism and an action mechanism are arranged on the detection frame. The user places the trip unit to be tested on a horizontal frame, and presses the power supply mechanism on the trip unit to energize the trip unit. After the power is energized, the T-bar on the trip unit automatically rotates, indicating that the production of the trip unit meets the requirements. The movement of the T-bar can be detected by a sensor. After the T-bar rotates, it is necessary to detect whether the T-bar can be toggled to reset. The user controls the extension of the second power piece so that the second power piece presses against the T-bar, which can achieve the effect of detecting the trip unit and improve the efficiency of detection.
[0009] Optionally, a plurality of mounting slots are provided on the horizontal frame, and a clamping block is detachably connected to the mounting slot, and the clamping block is used to abut against the outer wall of the release to be detected.
[0010] By adopting the above technical solution, a mounting groove is opened on the horizontal frame, and a clamping block is set in the mounting groove, so that the clamping block can be bolted or clamped in the mounting groove, and the clamping block abuts against the outer wall of the release, thereby fixing the release.
[0011] Optionally, the power supply mechanism includes a power part, a slider and multiple probes, the power part is installed on the vertical frame, the power part is connected to the slider, the power part drives the slider to move back and forth, the probe is installed on the slider, and the probe is used to be electrically connected to the release.
[0012] By adopting the above technical solution, a power part is set on the vertical frame, so that the power part drives the slider to move vertically back and forth through expansion and contraction. When the slider falls, the slider drives the probe to fall and abut against the pin of the release. The user can quickly connect the power supply to the release and energize the release by connecting the positive and negative poles of the power supply to the probe through wires.
[0013] Optionally, a slide rail is provided on the vertical frame, and the slider is embedded in and slidably connected to the slide rail.
[0014] By adopting the above technical solution, by arranging the slide rails on the vertical frame, the slide rails play a guiding role, which can reduce the probability of position deviation when the slider moves vertically.
[0015] Optionally, the probe is slidably connected to the slider.
[0016] By adopting the above technical solution, by making the probe slidably connected to the slider, when the movement accuracy of the power part 1 is low, the probe can abut against the release and slide relative to the slider, reducing the probability of the probe and the release being damaged by force.
[0017] Optionally, abutment members are provided at both ends of the power member, the abutment members are made of elastic material, and the abutment members are used to abut against the T-bar.
[0018] By adopting the above technical solution, an abutment piece is provided on the power part 2 so that the abutment piece abuts against the T-bar.

When the position of the T-bar on the releaser is relatively special, the user can control the mounting seat to rotate on the vertical frame, thereby extending the power member 2 so that the T-bar can be pushed.
[0021] Optionally, the power device includes a winding roller, a pull rope and a motor. The winding roller is rotatably connected to the vertical frame, one end of the pull rope is connected to the winding roller, and the other end is connected to the power component 2. The motor housing is fixed on the vertical frame, and the output shaft of the motor is coaxially connected to the winding roller.
[0022] By adopting the above technical solution, the length direction of the power part 2 is made perpendicular to the length direction of the rotating shaft, and the length direction of the rotating shaft is parallel to the length direction of the winding roller. By arranging a motor on the vertical frame, the motor can drive the winding roller to rotate, and then the winding roller reels in or releases the pull rope, thereby achieving the effect of controlling the swing of the power part 2.
[0023] In summary, the beneficial technical effects of this application are:
[0024] 1. By arranging a power supply mechanism and an actuating mechanism on the test frame, the user places the trip unit to be tested on a horizontal frame and presses the power supply mechanism against the trip unit to energize it. If the T-bar on the trip unit automatically rotates after power is energized, it indicates that the production of the trip unit meets the requirements. The movement of the T-bar can be detected by a sensor. After the T-bar rotates, it is necessary to test whether the T-bar can be reset. The user controls the extension of the second power member so that the second power member presses against the T-bar, which can effectively test the trip unit and improve the efficiency of the test.
[0025] 2. A power member is installed on the vertical frame, which drives the slider to move vertically back and forth through expansion and contraction. When the slider drops, the slider drives the probe to drop and abut against the pins of the trip unit. The user can quickly connect the power supply to the trip unit and energize the trip unit by connecting the positive and negative poles of the power supply to the probe through wires.
[0026] 3. By providing an abutment on the power part 2 so that the abutment abuts against the T-bar, when the movement accuracy of the power part 2 is low, the abutment can be deformed and abut against the T-bar, thereby reducing the chance of the power part 2 squeezing the release.

[0032] The present application is further described in detail below with reference to the accompanying drawings.
[0033] The present application embodiment discloses a trip unit testing device, referring to Figure 1 and Figure 2 , including a detection frame 1, a power supply mechanism 2 and an actuating mechanism 3. The detection frame 1 includes a horizontal frame 11 and a vertical frame 12. The horizontal frame 11 and the vertical frame 12 are perpendicular to each other and connected. The horizontal frame 11 is used to place the trip unit 5 to be tested. The power supply mechanism 2 is installed on the vertical frame 12. The power supply mechanism 2 is used to electrically connect to the trip unit 5 and supply power to the trip unit 5. When the trip unit 5 is powered, the T-shaped rod 51 on the trip unit 5 is actuated, thereby completing the tripping action. The actuating mechanism 3 is set on the vertical frame 12. The actuating mechanism 3 is used to push the T-shaped rod 51, thereby resetting the T-shaped rod 51. When the power supply mechanism 2 supplies power to the trip unit 5, the T-shaped rod 51 is actuated, indicating that the performance of the trip unit 5 meets the standard. After the actuating mechanism 3 pushes the T-shaped rod 51, it indicates that the mobility of the T-shaped rod meets the standard, finally completing the production quality inspection of the production trip unit 5.
[0034] Reference Figure 2 The horizontal frame 11 is provided with a plurality of mounting grooves 111, and a plurality of snap-in blocks 112 are detachably connected to the mounting grooves 111. The snap-in blocks 112 are used to snap on the outer wall of the trip unit 5, so that the trip unit 5 maintains a stable position on the detection frame 1, so that the power supply mechanism 2 and the action mechanism 3 can contact the components at predetermined positions on the trip unit 5.
[0035] Reference Figure 1 and Figure 2The power supply mechanism 2 includes a power member 21, a slider 22, and multiple probes 23. The power member 21 can be a pneumatic cylinder or an electric cylinder. The cylinder of the power member 21 is fixed to the vertical frame 12, and the piston rod of the power member 21 is connected to the slider 22. The power member 21 drives the slider 22 to move back and forth through expansion and contraction. The length of the power member 21 is perpendicular to the horizontal frame 11. The probes 23 extend through the slider 22 and are slidably connected to the slider 22. When the power member 21 drives the slider 22 downward, the probes 23 can fall and contact the terminals of the release 5. The user connects the positive and negative power supply wires to the probes 23, allowing the power supply to quickly connect to the release 5 and supply power to the release 5. By slidably connecting the probes 23 to the slider 22, when the expansion and contraction accuracy of the power member 21 is low, the probes 23 can abut the release 5 and slide relative to the slider 22, thereby reducing the chance of damage to the probes 23 and the release 5.
[0036] Reference Figure 1 The vertical frame 12 is provided with a slide rail 221, onto which the slider 22 is embedded and slidably connected. The slide rail 221 serves as a guide, reducing the chance of the slider 22 tilting during movement, thereby improving the movement accuracy of the probe 23. A position sensor can be installed on the underside of the slider 22. The sensor emits light that shines on the T-bar 51 of the trip unit 5, allowing the sensor to detect the position and displacement of the T-bar 51. The user can judge the production quality of the trip unit 5 based on the electrical signal emitted by the sensor.
[0037] Reference Figure 1 and Figure 2 The actuating mechanism 3 includes a second power member 31, which can be a pneumatic cylinder or an electric cylinder. The cylinder of the second power member 31 is fixed to the vertical frame 12, and the direction of the second power member 31 is toward the release 5. The second power member 31 pushes the T-shaped rod 51 by telescoping, thereby automatically resetting the T-shaped rod 51. The piston rod of the second power member 31 is provided with an abutment 32, which is made of an elastic material. When the actuating mechanism 3 moves the T-shaped rod 51, the abutment 32 contacts the T-shaped rod 51, thereby reducing the chance of the second power member 31 breaking the T-shaped rod 51.
[0038] Reference Figure 3 and Figure 4The vertical frame 12 is provided with an adjustment mechanism 4 for adjusting the angle of the power member 2 31 relative to the horizontal frame 11. When the trip unit 5 is placed on the horizontal frame 11, the T-bar 51 forms an angle relative to the horizontal frame 11 and the power member 2 31. When the trip unit 5 has a special shape, the power member 2 31 extends and abuts against the T-bar 51, making it difficult to move the T-bar 51, resulting in poor detection results. The user can use the adjustment mechanism 4 to rotate the power member 2 31 relative to the vertical frame 12. When the power member 2 31 extends and abuts against the T-bar 51, it can drive the T-bar 51 to rotate, thereby facilitating the detection of trip units 5 of different shapes.
[0039] Reference Figure 3 and Figure 4 The direction adjustment mechanism 4 includes a mounting seat 41, a rotating shaft 42 and a power device. The mounting seat 41 is fixedly connected to the power member 2 31. The rotating shaft 42 is horizontally arranged on the mounting seat 41. The rotating shaft 42 is rotatably connected to the vertical frame 12. The power device is installed on the vertical frame 12. The power device is used to drive the power member 2 31 to move, so that the power member 2 31 can rotate with the rotating shaft 42 as the rotating axis, thereby achieving the effect of adjusting the angle between the power member 2 31 and the vertical frame 12.
[0040] Reference Figure 3 and Figure 4 The power device includes a winding roller 43, a pull rope 44, and a motor 45. The winding roller 43 is parallel to the rotating shaft 42 and is rotatably connected to the vertical frame 12. The winding roller 43 is located above the mounting base 41. One end of the pull rope 44 is fixed to the winding roller 43, and the other end is connected to the second power member 31. The housing of the motor 45 is fixed to the vertical frame 12, and the output shaft of the motor 45 is coaxially connected to the winding roller 43. When the motor 45 drives the winding roller 43 to rotate, the winding roller 43 reels or releases the pull rope 44, thereby allowing the second power member 31 to swing on the vertical frame 12.
[0041] The implementation principle of the embodiment of the present application is as follows: by arranging a power supply mechanism 2 on the detection frame 1, the power piece 1 21 can drive the slider 22 to fall vertically, and then the power supply is quickly connected to the tripper 5 through the probe 23 and supplies power to the tripper 5. After the tripper 5 is energized, the T-bar 51 moves, and the sensor on the slider 22 detects the movement of the T-bar 51. By arranging an action mechanism 3 on the detection frame 1, the power piece 2 31 can extend and push the T-bar 51, thereby achieving the effect of detecting the activity of the T-bar 51.
[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
