Description

Technical Field

[0001] The present disclosure relates to the technical field of SVG detection, and in particular to an SVG module testing device. Background Art

[0002] SVGs (static var generators) play a vital role in power systems. They dynamically absorb and generate reactive power, maintaining reactive power balance. This balance is crucial for improving power system stability and voltage quality. SVGs can also adjust the magnitude and phase of reactive current in real time based on load changes, reducing power loss and overall system energy consumption.

[0003] Therefore, SVG maintenance is crucial to power systems. During SVG maintenance, all IGBT modules must be tested to verify proper operation. During module testing, the tester attaches a test lead clip to the module under test and then uses a tester to output voltage and / or current for the module. If the IGBT modules are spaced far apart, the tester must constantly switch test lead clips between modules, requiring time-consuming and labor-intensive back-and-forth between the modules and the tester.

Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise indicated, identical reference numerals in different drawings represent identical or similar elements. The above definitions are intended solely to explain and illustrate this disclosure and should not be construed as limiting the disclosure.

[0025] According to the specific embodiment of the present disclosure, Figure 1 As shown in the figure, an SVG module testing device is provided, which includes: a device body 100, the device body 100 is used to provide a test voltage and / or test current to the module to be tested, and the device body 100 is formed with a mounting portion; a test wire clamp, the two ends of the test wire clamp are respectively connected to the device body 100 and the module to be tested, so that the device body 100 and the module to be tested are connected in parallel; and an operating member 200, the operating member 200 is electrically connected to the device body 100 and can be detachably installed on the mounting portion, the operating member 200 includes an operating area 210 and a display area 220, the operating area 210 is used to control the connection status between the device body 100 and the module to be tested, and the display area 220 is used to display information of the test voltage and / or test current.

[0026] Through the above technical solution, in the SVG module testing device provided by the present disclosure, the operating member 200 can be detachably mounted on the mounting portion of the device body 100, and the operating member 200 can control the connectivity between the device body 100 and the module under test. Thus, during the testing of the module under test, the operator can carry the operating member 200 throughout the entire process and operate the operating area 210 to cause the device body 100 to provide a test voltage and / or test current to the module under test to test the module under test, without having to return to the device body 100 for operation. Therefore, the SVG module testing device can improve testing efficiency while saving manpower.

[0027] In the SVG module testing device provided by the present disclosure, the operation area 210 can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 2As shown in , the operating area 210 can be provided with a first knob, which can be used to power on or off the module to be tested and the device body 100. The display area 220 can include a first display screen 221 and a display light 222. The first display screen 221 can be used to display the numerical value of the test voltage and / or test current, and the display light 222 can be used to show the state of the test voltage and / or test current. In this way, when it is necessary to test the module to be tested, the staff can rotate the first knob to make the device body 100 provide the test voltage and / or test current to the module to be tested, and can observe the numerical value of the test voltage and / or test current through the first display screen 221 to ensure that the device body 100 is in a normal state. If the numerical value of the test voltage and / or test current does not meet the requirements for testing the module to be tested, it is necessary to check the device body 100 in time to ensure the accuracy of the test results of the module to be tested. In addition, the display light 222 can also remind the staff whether the current test voltage and / or test current can meet the requirements for testing the module to be tested.

[0028] There are multiple display lights 222, and the multiple display lights 222 can be different colors and selectively light up to distinguish the current status of the test voltage and / or test current. In addition, different words can be marked under the display lights 222 to enhance the reminder effect. In an exemplary embodiment, the number of display lights 222 can be four, and the four display lights 222 can be red, green, yellow and orange respectively, and the word "fault" can be marked under the red display light. When the red display light is on, it indicates that the test voltage and / or test current currently provided by the device body 100 does not meet the requirements of the test module to be tested, and the staff needs to check the device body 100 in time; the word "power" can be marked under the green display light. When the green display light is on, it indicates that the test voltage and / or test current currently provided by the device body 100 can meet the requirements of the test module to be tested; the word "undervoltage" can be marked under the yellow display light. When the yellow display light is on, it indicates that the test voltage and / or test current currently provided by the device body 100 is lower than the voltage and / or current of the test module to be tested; the word "overvoltage" can be marked under the orange display light. When the orange display light is on, it indicates that the test voltage and / or test current currently provided by the device body 100 is higher than the voltage and / or current of the test module to be tested.

[0029] In the SVG module testing device provided in the present disclosure, the device body 100 and the operating member 200 can be connected in any suitable manner. As an exemplary embodiment, refer to Figures 1 to 3As shown in FIG, the device body 100 may include a test box, which may be electrically connected to the operating member 200 via a connecting line 300. The test box may include a first box body 110 and a second box body 120 that are rotatably connected. An operating platform may be provided on the side of the first box body 110 facing the second box body 120. A mounting portion may be provided on the operating platform and configured as a mounting groove 111. The operating platform may be recessed away from the second box body 120 to form the mounting groove 111. The shape of the mounting groove 111 may be adapted to the shape of the operating member 200, and the operating member 200 may be at least partially mounted in the mounting groove 111. Thus, when operation is required on the device body 100, the operating member 200 may be mounted in the mounting groove 111 and the first knob may be rotated. Furthermore, when no test module is required, the operating member 200 may be mounted in the mounting groove 111 to facilitate storage of the operating member 200. In other embodiments, the operating member 200 may be electrically connected to the test box via other suitable wireless connection methods, and this disclosure is not particularly limited in this regard.

[0030] Here, “the operating member 200 is at least partially installed in the installation groove 111 ” can be understood as part of the operating member 200 is accommodated in the installation groove 111 , and the other part protrudes from the surface of the operating platform to facilitate the staff to access the operating member 200 .

[0031] In the SVG module testing device provided in the present disclosure, in order to facilitate the use of the operating member 200, as an exemplary embodiment, reference is made to Figure 1 and Figure 2 As shown in FIG, operating grooves 1111 may be symmetrically arranged on opposite sides of the mounting groove 111. The operating grooves 1111 may be connected to the mounting groove 111 and recessed away from the mounting groove 111. The operating grooves 1111 may be configured in a semicircular shape. In this way, a worker can insert their fingers into the operating grooves 1111 and pick up the operating member 200 from opposite ends.

[0032] In the SVG module testing device provided in the present disclosure, as an exemplary embodiment, reference is made to Figure 2As shown in , the operating platform can be arranged with a first interface portion 1121 and at least one group of second interface portions 1122. The first interface portion 1121 can be used to provide a preset test current for the module under test, and the second interface portion 1122 can be used to provide a preset test voltage for the module under test. The module under test can be selectively connected to the first interface portion 1121 and / or a group of second interface portions 1122 via a test clip. The first interface portion 1121 and each group of second interface portions 1122 each include a first interface and a second interface. In this way, when it is necessary to connect the module under test to the first interface portion 1121 or a group of second interface portions 1122, the staff can respectively plug the first ends of the two test clips into the corresponding first interface and second interface, and respectively clamp the second ends of the two test clips on the module under test, so that the module under test is connected in parallel with the device body 100.

[0033] It should be noted that "the module under test is selectively connected to the first interface portion 1121 and / or a group of second interface portions 1122 via a test line clamp" includes the following three embodiments: Embodiment 1: The module under test is connected to the first interface portion 1121 via a test line clamp, so that the first interface portion 1121 can provide a preset test current for the module under test; Embodiment 2: The module under test is connected to a group of second interface portions 1122 via a test line clamp, so that the second interface portion 1122 can provide a preset test voltage for the module under test; Embodiment 3: The module under test is simultaneously connected to the first interface portion 1121 and a group of second interface portions 1122 via a test line clamp, so that the first interface portion 1121 can provide a preset test current for the module under test, and the second interface portion 1122 can provide a preset test voltage for the module under test. In addition, the test voltages provided by each group of second interface portions 1122 are different. As an exemplary embodiment, the number of second interface parts 1122 can be three groups, wherein two groups of second interface parts 1122 can provide 120V and 600V AC test voltages for the module to be tested respectively, and the other group of second interface parts 1122 can provide 600V DC test voltage for the module to be tested. In other embodiments, the number of second interface parts 1122 and the test voltages they provide can also be constructed in other suitable ways, and the present disclosure does not impose any specific restrictions on this.

[0034] In addition, the operating platform may also be provided with a second knob 114, which can be used to control the test current output by the first interface portion 1121. Thus, by rotating the second knob 114, a staff member can cause the first interface portion 1121 to output different test currents to the module under test. As an exemplary embodiment, the second knob 114 can be provided with three gears, which can respectively control the first interface portion 1121 to output test currents of 5A, 8A, and 10A. In other embodiments, the gears of the second knob 114 and the test current value output by the first interface portion 1121 can also be configured in other suitable manners, and this disclosure does not impose specific limitations on this.

[0035] In order to facilitate the staff to select the appropriate test voltage and / or test current, the corresponding voltage values can be marked next to different second interface parts 1122, and the corresponding current values can be marked next to different gears of the second knob 114.

[0036] In the SVG module testing device provided in the present disclosure, as an exemplary embodiment, reference is made to Figure 1 and Figure 2 As shown in , the SVG module testing device may further include at least one heat dissipation zone 113. Heat dissipation zone 113 may be located on a wall of the first housing 110 perpendicular to the operating platform. Each heat dissipation zone 113 may include a plurality of spaced-apart strip-shaped heat dissipation holes. This allows heat dissipation from the circuits and components within the first housing 110 to be dissipated through heat dissipation zone 113, thereby extending the service life of the SVG module testing device.

[0037] In the SVG module testing device provided in the present disclosure, as an exemplary embodiment, reference is made to Figure 1 and Figure 2 As shown in FIG, the operating platform is provided with a power interface 115, which is connected to an external power source via a power line. In this way, the SVG module test device can be powered by the external power source to ensure the operation stability of the SVG module test device.

[0038] In the SVG module testing device provided in the present disclosure, the first box 110 and the second box 120 can be connected in any suitable manner. As an exemplary embodiment, refer to Figure 1 As shown in FIG, the first housing 110 has a first side and a second side arranged opposite each other, and the second housing 120 has a third side and a fourth side arranged opposite each other. The first side is rotatably connected to the third side, and the second side is locked to the fourth side via a latch. Thus, when the test chamber is not in use, the first and second housings 110 and 120 can be locked together via the latch to prevent damage to the components on the operating platform. When the module under test is to be tested, the second housing 120 can be rotated open to operate the operating member 200.

[0039] In the SVG module testing device provided in the present disclosure, as an exemplary embodiment, reference is made to Figure 1 and Figure 2 As shown in FIG, a handle 116 may be provided on the first box body 110 or the second box body 120.

[0040] In the SVG module testing device provided in the present disclosure, the operating platform can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 1 As shown in , the operating platform can also be provided with a second display screen 117, a switch 118, an indicator light 119 and a communication interface 1110. The second display screen 117 has the same content as that displayed on the first display screen 221, so that the staff can observe the numerical value of the test voltage and / or test current on the device body 100. The switch 118 is used to control the connectivity between the test device and the external power supply, so that when the test device is connected to the external power supply, the test device can be turned on or off by operating the switch 118 to avoid repeatedly plugging and unplugging the power cord. The indicator light 119 is used to display the power on and off status of the test device. When the test device is powered on, the indicator light 119 lights up to remind the staff that the test device can be used to test the module to be tested. When the test device is powered off, the indicator light 119 goes out. The communication interface 1110 can be plugged with an optical fiber, so that the optical fiber can be used to provide a communication signal to the module to be tested, so as to avoid the module to be tested prompting "communication failure" and affecting the test process.

[0041] In addition, in order to facilitate the collection of the wiring harness, as an exemplary embodiment, reference is made to Figure 3 As shown in the figure, the second box body 120 can be provided with a cable tie 121 and a wiring box 122. The cable tie 121 can be constructed as a Velcro strap, a part of the Velcro strap is fixed to the inner wall of the second box body 120, and the other part can be rolled up to tighten the wiring harness (such as a test wire clamp, a power cord, etc.). The second box body 120 may include a first plate body and a plurality of side panels connected to the first plate body along the circumference of the first plate body. The second box body 120 also includes a baffle extending from the third side toward the fourth side. The baffle and the first plate body and the plurality of side panels surround a wiring box 122 with an opening on one side. The wiring box 122 is used to accommodate the wiring harness (such as a test wire clamp, a power cord, etc.).

[0042] During use of the SVG module testing device provided by the present disclosure, a staff member connects the first end of the test clip to the device body 100 and clamps the second end of the test clip on the module to be tested. During the above process, the staff member carries the operating member 200 throughout the process and operates the operating area 210 to connect the device body 100 with the module to be tested. In this way, the device body 100 can provide a test voltage and / or a test current to the module to be tested to test the module to be tested. After the staff member has finished testing the current module to be tested, he or she only needs to carry the second end of the test clip and the operating member 200 at the same time and go to the next module to be tested, without having to return to the device body 100, thus saving time and effort.
