Description

Technical Field

[0001] The present application relates to the technical field of motor control electrical testing devices, and in particular to a shaking controller tester. Background Art

[0002] In continuously operating industries such as petroleum, chemical, and metallurgy, fluctuations in grid voltage can cause equipment downtime, resulting in significant economic losses. A power-swing controller effectively prevents contactor tripping caused by voltage drops during power fluctuations, ensuring the contactor remains closed during power fluctuations, thus ensuring continuous equipment operation.

[0003] In the prior art, for example, the anti-power-shaking controller test device disclosed in the patent document with application number 201921187534.4 provides a technical solution that can simulate power shaking after the anti-power-shaking controller is produced to test whether the anti-power-shaking controller functions normally. Figure 4 During testing, the multiple terminal pins of the anti-sway controller are inserted into the multiple connection holes of the electrical connection base. After testing, the multiple terminal pins of the anti-sway controller are removed from the multiple connection holes. However, the test device needs to handle large-scale testing of anti-sway controllers. The electrical connection terminals in the connection holes are generally traditional sockets that match the terminal pins. After repeated use, the sockets are prone to wear, resulting in poor contact and inaccurate test results. Moreover, the electrical connection base itself has multiple wiring parts, and removing it from the test device and replacing it is very time-consuming and labor-intensive. Utility Model Content

Unless otherwise defined, all technical and scientific terms used in this document have the same meaning as those generally understood by technicians in the technical field of the present invention. It should also be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The terms used in this document in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation.

[0031] Please refer to Figure 1 - Figure 10 This embodiment provides a tester for a power oscillation controller, comprising an electrical connection base 100, a drive device 200, and a guide device 300. The electrical connection base 100 is provided with a plurality of connection holes 101 correspondingly plugged into the terminal pins of the power oscillation controller. The upper and lower sidewalls of the electrical connection base 100 are provided with wiring portions 102 electrically connected to the connection holes. Fixed spring terminals 400 within the plurality of connection holes 101 are electrically connected to the corresponding wiring portions 102 via wires. The wiring portions 102 are electrically connected to other components of the tester.

[0032] The connecting hole 101 is provided with a fixed spring terminal 400 connected to the side wall of the connecting hole 101 and an adjustable spring terminal 500 arranged relative to the fixed spring terminal 400; the driving device 200 includes a driving seat 201, a driver, and a connecting rod 203; one end of the connecting rod 203 is connected to the driving seat 201, and the other end is connected to the adjustable spring terminal 500; the driver is used to drive the driving seat 201 to drive multiple adjustable spring terminals 500 to move relative to the fixed spring terminal 400; the guide device 300 is connected to the driving seat 201, and is used to limit the moving direction of the driving seat 201.

[0033] When the electric shock controller is not inserted into the multiple connection holes 101 through the terminal rod feet, the driving device 200 drives the driving seat 201, and the driving seat 201 drives the connecting rod 203 and the multiple adjustable spring terminal 500 to move away from the fixed spring terminal 400, so that the socket enclosed by the adjustable spring terminal 500 and the fixed spring terminal 400 in each group of connection holes 101 is expanded to be larger than the outer diameter of the terminal rod feet. In this way, when the terminal rod feet are inserted into the multiple connection holes 101, there is basically no friction with the adjustable spring terminal 500 and the fixed spring terminal 400, and naturally no wear of the adjustable spring terminal 500 and the fixed spring terminal 400 will be caused.

[0034] When the power-swing controller is connected to the power connection base 100, the drive device 200 drives the drive base 201, which in turn drives the connecting rod 203 and the plurality of adjustable spring terminals 500 toward the fixed spring terminals 400, pressing against the outer wall of the terminal rod foot. This ensures that both the adjustable spring terminals 500 and the fixed spring terminals 400 are tightly against the terminal rod foot, forming a stable connection and preventing poor contact. This ensures that the power-swing controller is tested, ensuring accurate test results.

[0035] When testing is complete, the power-shaking controller needs to be disconnected from the power connection base 100. The driver 200 drives the driver base 201, which in turn moves the connecting rods 203 and the multiple adjustable spring terminals 500 away from the fixed spring terminals 400. This expands the sockets enclosed by the adjustable spring terminals 500 and the fixed spring terminals 400 within each set of connection holes 101 to a size larger than the outer diameter of the terminal rod legs. The power-shaking controller can then be removed.

[0036] In this way, the electrical connection terminals in the plurality of connection holes 101 are guaranteed to have a longer service life, and are prevented from being worn out too quickly, and the time-consuming and labor-intensive frequent replacement of the electrical connection base 100 is avoided.

[0037] In some embodiments, the driver may be a device such as a cylinder or an electric push rod that can achieve linear reciprocating drive.

[0038] The guide device 300 limits and guides the driving seat 201, so that the adjustable spring terminal 500 can move accurately.

[0039] Please refer to Figure 7 - Figure 10 The fixed spring terminal 400 includes a spring portion 401, a wiring hole 402, a fixing hole 403, and a locking hole 404. The locking hole 404 is connected to the wiring hole 403; the locking hole 404 is penetrated by a screw to fix the wire in the wiring hole 402; the fixed spring terminal 400 is detachably connected to the connection position of the side wall of the connecting hole 101 through the fixing hole 403; the adjustable spring terminal 500 includes a spring portion 501 and a mounting hole 502; the mounting hole 502 is penetrated by a screw, and the adjustable spring terminal 500 is detachably connected to the connecting rod 203 The drive seat 201 is a rack, the electrical connection base 100 is provided with a avoidance hole 103 corresponding to the rack, the guide device 300 is a guide slide, the rack passes through the guide hole of the guide slide, and is slidably connected to the guide slide; the driver includes a servo motor 202, a reducer 203, and a gear 204; the reducer 203 is connected to the power output end of the servo motor 202, the gear 204 is connected to the power output end of the reducer 203, and the gear 204 is meshed with the rack; the power output end of the reducer 203 is provided with an angle limiter.

[0040] The end of the wire is inserted into the wiring hole 402, and a screw is passed through the locking hole 404 to fix the wire in the wiring hole 402. The other end of the wire is connected to the corresponding wiring part 102.

[0041] The fixed spring terminal 400 is detachably connected to the connection point on the side wall of the connecting hole 101 through the fixing hole 403, allowing the fixed spring terminal 400 to be replaced separately. The adjustable spring terminal 500 is detachably connected to the connecting rod 203 by screws passing through the mounting hole 502, allowing the adjustable spring terminal 500 to be replaced separately.

[0042] The multiple adjustable spring terminals 500 are connected to the rack through the connecting rod 203, so that the multiple adjustable spring terminals 500 can move synchronously.

[0043] In some embodiments, the angle limiting member is a fixed rod 601 provided on the housing of the reducer 203, and a stop rod 602 provided on the power output shaft of the reducer 203. When the servo motor 202 outputs excessive power, the stop rod 602 can abut against the fixed rod 601 to limit the rotation output amplitude, thereby achieving precise movement of the rack.

[0044] Currently, testing and inspecting a sway controller usually requires on-site inspection personnel to connect the sway controller to the motor circuit. This also has the disadvantages of cumbersome wiring operations, poor safety, and low intelligence. This application provides the following solutions to solve this problem:

[0045] Please refer to Figure 1-3 , this embodiment provides a shaking power controller tester, hereinafter referred to as the tester.

[0046] The tester control circuit and the voltage-regulated power supply circuit are connected between the N and L terminals of the 220VAC power supply.

[0047] The tester control circuit includes an electrical connection base, a main control circuit, a motor control circuit and a locking circuit; the electrical connection base is used to plug and unplug the shaking power controller, and the electrical connection base includes at least four pairs of terminals, which are respectively connected to the main control circuit, the motor control circuit and the locking circuit to realize plug-and-play testing of the shaking power controller.

[0048] The voltage-regulated power supply circuit includes a voltage-regulating control circuit, a 220VAC power supply branch, and a voltage-regulated power supply branch. The voltage-regulating control circuit controls the switching and interlocking of the 220VAC power supply branch and the voltage-regulated power supply branch, and can adjust different amplitudes of power fluctuations, meeting the requirements of various motor anti-power fluctuation tests.

[0049] The 220VAC power supply branch is connected in series with the circuit breaker GF1 and the normally closed undervoltage relay contact KA. The high-voltage side of the 220VAC power supply branch is connected to the AC 220VACL terminal, and the low-voltage side is connected to the tester control circuit. The normally open delayed disconnect contact KT2 is connected in parallel with the normally closed undervoltage relay contact KA.

[0050] The voltage-regulated power supply branch is connected in series with the circuit breaker GF2, the voltage regulator TC and the normally closed delayed opening contact KT2, and is connected in parallel with the 220VAC power supply branch.

[0051] The voltage regulation control circuit is connected between the L and N terminals of the 220VAC power supply, including the undervoltage relay coil KA connected in series with the normally open voltage regulation button SB4, the normally closed undervoltage relay contact KA connected in series with the reset circuit of the power-off delay relay KT2 and the 220VAC power supply circuit, and the auxiliary normally open contact KA connected in series with the voltage regulator TC branch.

[0052] The main control circuit includes a series circuit formed by the normally open start button SB1, the power-on delay relay KT1, the normally open delayed closing contact KT1 of the power-on delay relay KT1, and the power connection base terminals 1-2, and a series branch formed by the normally closed stop button SB2, the normally open start button SB1 and the main control coil KM; the series branch formed by the normally closed stop button SB2, the normally open start button SB1 and the main control coil KM is connected in parallel with the branch formed by the normally open start button SB1, the power-on delay relay KT1, and the normally open delayed closing contact KT1, which is used to allow the tester to manually set the power shaking duration.

[0053] The motor control circuit includes a branch 11 in which the normally open main control contact KM and the running indicator light HG are connected in series, and a branch 15 in which the normally closed main control contact KM and the stop indicator light HR are connected in series; the normally open main control contact KM is connected in parallel with the normally open start button SB1, and the normally open delayed closing contact 6-8 between the terminals 6-8 of the base is electrically connected in parallel with the normally open start button SB1; the normally open main control contact KM is connected in series between the terminals 3-4 of the base to form a loop; branches 11 and 15 are connected in parallel with the branch where the normally open start button SB1 and the main control coil KM are located.

[0054] The locking circuit includes a series branch formed by the normally open delayed closing contact 5-7 connected between the terminals of the base 5-7 and the locking indicator light HY, which is used to indicate whether the power shaking controller is working normally.

[0055] A miniature circuit breaker GF4 is connected between the tester control circuit port and the voltage regulating power supply circuit port to protect the circuit.

[0056] The method for detecting the power shaking controller using the detector of the utility model is as follows.

[0057] Connect the power cord and turn on the 220VAC power supply.

[0058] The tester is powered by a 220VAC power supply, which means that the current flows through the L terminal of the 220VAC power supply, through the circuit breaker GF0, the fuse GF2, the circuit breaker GF1, the normally closed undervoltage relay contact KA, the miniature circuit breaker QF4 and reaches the tester control circuit port. The other port of the tester control circuit is connected to the N terminal of the 220VAC power supply.

[0059] The normally closed shaking button SB3 is in the closed state, the power-off delay relay KT2 is energized, the contacts TA6-8 are closed, and the current flows through branch 5; the stop button SB2 is a normally closed button, the normally closed main control contact KM is closed, the current flows through branch 7 to branch 15, and the stop indicator light HR is lit.

[0060] At this time, the running indicator light HG is off, the stop indicator light HR is on, and the locking indicator light HY is off.

[0061] Insert the power controller into the power connection base.

[0062] Press the start button SB1 to start the motor.

[0063] After the start button SB1 is pressed, the current passes through branch 9, the main control coil KM is energized, the normally closed main control contact KM is disconnected, and the normally open main control contact KM is closed.

[0064] At this time, the running indicator light HG is on, the stop indicator light HR is off, and the locking indicator light HY is off.

[0065] Set the power-off delay relay KT2 shaking time.

[0066] Press the power-shaking button SB3 and observe the status of the indicators on the user panel.

[0067] Pressing the power-on button SB3 de-energizes the motor. In the tester's control circuit, the power-off delay relay KT2 de-energizes, the normally open delayed closing contact KT1 opens, the main control coil KM de-energizes, and the power connector base terminals 3-4 disconnects, activating the power-on controller. When the time set for the power-off delay relay KT2 expires, the normally open delayed closing contact KT1 closes. If the power-on time set for the power-off delay relay KT2 is within the permitted power-on time, the power-on controller forces the motor to run. The normally open delayed closing contacts between terminals 5-7 and 6-8 of the power connector base close and then open. At this point, the run indicator HG turns on, the stop indicator HR turns off, and the lockout indicator HY turns off. If the power-off time set for the power-off delay relay KT2 exceeds the permitted power-on time, the motor stops, the run indicator HG turns off, the stop indicator HR turns on, and the lockout indicator HY turns off.

[0068] Set the voltage swing voltage of the voltage regulator TC, press the normally open voltage regulator button SB4, and observe the display status of each indicator light on the user panel.

[0069] The power-off delay relay KT2 has a counting function, and the counting button is a normally closed button and is in the closed state; after pressing the normally open voltage regulating button SB4, the undervoltage relay coil KA is energized, the normally closed undervoltage relay contact KA is disconnected, the 220VAC power supply circuit is disconnected, and the normally closed undervoltage relay contact KA of the branch where the voltage regulator TC is located is closed. At this time, the voltage regulator TC supplies power to the tester control circuit; after the power-off delay relay KT2 coil is energized, the normally open delayed disconnection contact KT2 is delayed closed, and the normally closed delayed disconnection contact KT2 is delayed disconnected. After the delay set time is up, it resets and restores the 220VAC power supply circuit to supply power to the tester control circuit, which simulates the motor power failure process.

[0070] Compared with the existing technology, the utility model provides a swaying controller tester that can realize plug-and-play testing of the swaying controller, which is more convenient and practical; the display indicator lights, buttons, adjustment knobs, etc. make the tester have a more friendly user interface, which can display multiple working states, so that the operator can easily adjust the swaying voltage and duration to test and observe the swaying controller. The main control circuit can adjust the power-off swaying duration, and the voltage-regulating power supply circuit can adjust different sway drops. It is suitable for various motor anti-swaying test needs and enhances the flexibility and adaptability of the tester.

[0071] Please refer to Figure 5 The tester specifically includes a box 700 and a power switch 800. The various physical components of the tester are installed in the box 700, and the components for interactive control or indicating status are exposed on the surface of the box 700. This makes the device a standardized overall tester.

[0072] In some embodiments, the working power supply of the present electric shaking controller detector is AC220V. After the power switch 800 is turned on, the corresponding connection part 102 will have a 220V voltage for power supply.
