[0093] Specifically, in some embodiments, please refer to Figure 1 、 Figure 2 and Figure 3The present application provides a data center terminal cabinet testing device for detecting a data center terminal cabinet 70. The data center terminal cabinet testing device may include a pre-electrical testing device and a control component 30. The pre-electrical testing device is used to perform a pre-electrical test on the data center terminal cabinet 70. It may include a continuity test component 10 and an insulation test component 20. The continuity test component 10 is used to perform a continuity test on the data center terminal cabinet 70. The insulation test component 20 is used to perform an insulation test on the data center terminal cabinet 70 to ensure the safety and reliability of the circuit of the data center terminal cabinet 70. The on-off test assembly 10 may include an on-off test module 11 and multiple on-off contactors 12. The on-off test module 11 has multiple on-off test paths 111. The on-off test paths 111 are used to be respectively connected to each phase input terminal 71 and each branch output terminal 72 of the data center terminal cabinet 70. The on-off contactors 12 are respectively arranged on each on-off test path 111. When the on-off contactor 12 is turned on, the on-off test path 111 is turned on. When the on-off contactor 12 is turned off, the on-off test path 111 is turned off. The insulation test assembly 20 may include an insulation test module 21 and multiple insulation contactors 22. The insulation test module 21 has multiple insulation test paths 211 and a box test path 212. The insulation test paths 211 are used to respectively connect to the phase input terminals 71, the branch output terminals 72, and the neutral terminal 73 of the data center terminal cabinet 70. The insulation contactors 22 are respectively arranged on each insulation test path 211. When the insulation contactor 22 is connected, the insulation test path 211 is connected. When the insulation contactor 22 is disconnected, the insulation test path 211 is disconnected. The box test path 212 is used to connect to the box of the data center terminal cabinet 70. The control assembly 30 includes components respectively connected to the on-off contactor 12 and the insulation contactor 22 to control the connection or disconnection of the on-off contactor 12 and the insulation contactor 22.

[0094] It can be understood that the phase input terminal 71 of the data center terminal cabinet 70 can generally include phase A, phase B and phase C, and the branch output terminal 72 can generally include output terminals 1 to 72, among which output terminal 1, output terminal 4, output terminal 7... output terminal 70 corresponds to A, output terminal 2, output terminal 5, output terminal 8... output terminal 71 corresponds to B, and output terminal 3, output terminal 6, output terminal 9... output terminal 72 corresponds to C. The data center terminal cabinet testing equipment of the present application connects the phase input terminal 71 and the branch output terminal 72 of the data center terminal cabinet 70 with the on-off test module 11 and the insulation test module 21 through the on-off test path 111 and the insulation test path 211, and controls the control component 30 to connect some of the on-off test paths 111 or the insulation test paths 211 separately, so that the on-off test module 11 or the insulation test module 21 can perform on-off test and insulation test on each phase input terminal 71 and branch output terminal 72 of the data center terminal cabinet 70.

[0095] For example, the control component 30 controls the on-off contactor 12 located on the on-off test path 111 connected to the A-phase input terminal to be turned on, and controls the on-off contactor 12 located on the on-off test path 111 connected to the 1-way output terminal to be turned on, thereby forming an on-off test circuit for testing the A-phase input terminal and the 1-way output terminal, so that the on-off test module 11 can test whether the A-phase input terminal and the 1-way output terminal are conductive.

[0096] The control component 30 controls the on-off contactor 12 on the on-off test path 111 connected to the A-phase input terminal and the on-off contactor 12 on the on-off test path 111 connected to the B-phase input terminal to form an on-off test circuit for testing the A-phase input terminal and the B-phase input terminal, so that the on-off test module 11 can detect whether there is conduction between the A-phase input terminal and the B-phase input terminal.

[0097] The insulating contactor 22 on the insulation test path 211 connected to the output terminal 1 is connected through the control component 30 to form an insulation test circuit for testing the output terminal 1 and the neutral terminal 73, so that the insulation test module 21 can test whether there is insulation between the output terminal 1 and the neutral terminal 73.

[0098] In summary, the present application can control the connection and disconnection of the on-off contactor 12 and the insulating contactor 22 through the control component 30, and can automatically switch the test module and test circuit, reduce the steps of manual operation, and achieve more efficient and safer automated testing.

[0099] Optionally, in some embodiments, the on-off test module 11 can be implemented as a test module such as a light bulb or a buzzer, and whether the circuit is connected is determined based on whether the light bulb lights up or the buzzer sounds. If the light bulb lights up or the buzzer sounds, the circuit is connected; if the light bulb does not light up or the buzzer does not sound, the circuit is disconnected.

[0100] Optionally, in some embodiments, the insulation testing module 21 can be implemented as a resistance testing module, and whether insulation is present can be determined by testing whether the resistance of the circuit is too large or too small.

[0101] Further, if Figure 1 、 Figure 4 and Figure 5 As shown, in some embodiments, the data center terminal cabinet test equipment of the present application may further include an electrical test device, which may include an AC power supply component 40, a load component 50, and an electrical parameter test component 60. The AC power supply component 40 may include an AC power supply module 41 and a plurality of power contactors 42. The AC power supply module 41 has a plurality of power output paths 412, which are used to be respectively connected to each phase input terminal 71 of the data center terminal cabinet 70. The AC power supply module 41 can be connected to an external mains power supply, and the external mains power supply is connected to the data center terminal cabinet 70 to provide power support when the data center terminal cabinet 70 is subjected to electrical testing. The power contactors 42 are respectively arranged on each power output path 412. When the power contactor 42 is connected, the power output path 412 is conductive, and when the power contactor 42 is disconnected, the power output path 412 is disconnected. The load assembly 50 includes a load module 51 and multiple load contactors 52. The load module 51 has multiple load input channels 511 and load output channels 512. The load input channels 511 are connected to the branch output terminals 72 of the data center terminal cabinet 70, and the load output channels 512 are connected to the neutral terminal 73 of the data center terminal cabinet 70. The load module 51 can be considered an electrical appliance, providing load support when the data center terminal cabinet 70 is conducting electrical testing. The load contactors 52 are respectively provided in each load input channel 511. When the load contactors 52 are connected, the load input channels 511 are connected, and the load module 51 is powered and operational. When the load contactors 52 are disconnected, the load input channels 511 are disconnected, and the load module 51 is powered and inoperative. The control assembly 30 is connected to the power contactor 42 and the load contactor 52 to control the power contactor 42 and the load contactor 52 to connect or disconnect. The electrical parameter testing component 60 is used to be electrically connected to each branch output terminal 72 and the neutral terminal 73 of the data center terminal cabinet 70, and can be used to test the voltage, current, power and other electrical parameters of each branch output terminal 72.

[0102] It is understood that the data center terminal cabinet test equipment of the present application connects the AC power module 41 to each phase input terminal 71 of the data center terminal cabinet 70 via the power output path 412, and connects the load module 51 to each branch output terminal 72 of the data center terminal cabinet 70 via the load input path 511. By controlling the power contactors 42 and load contactors 52 on some power output paths 412 and load input paths 511 to be connected, some electrical test loops can be formed. The electrical parameter test component 60 can be used to test the electrical parameters of the branch output terminals 72 in the electrical test loops, thereby achieving electrical testing of the data center terminal cabinet 70.

[0103] For example, the control component 30 controls the power contactor 42 on the power output path 412 connected to the A-phase input terminal to form an electrical test circuit for testing the phase-to-phase voltage of the A-phase input terminal. The electrical parameter test component 60 can test and obtain the voltage between the output terminal 1 corresponding to the A-phase input terminal and the neutral terminal 73, which is the phase-to-phase voltage between the A-phase input terminal and the neutral terminal 73.

[0104] The control component 30 controls the power contactors 42 on the power output paths 412 connected to the A-phase input terminal and the B-phase input terminal to form an electrical test circuit for testing the line-to-line voltage between the A-phase input terminal and the B-phase input terminal. The electrical parameter test component 60 can test and obtain the voltage between the 1st output terminal corresponding to the A-phase input terminal and the 2nd output terminal corresponding to the B-phase input terminal, which is the line-to-line voltage between the A-phase input terminal and the B-phase input terminal.

[0105] The control component 30 controls the power contactor 42 on the power output path 412 connected to the A-phase input terminal and the load contactor 52 on the load input path 511 connected to the output terminal 1 to respectively connect, thereby forming an electrical test circuit for testing the output current and output power of the output terminal 1. The output current and output power of the output terminal 1 can be tested by the electrical parameter test component 60.

[0106] In summary, the present application can control the connection and disconnection of the power contactor 42 and the load contactor 52 through the control component 30, and can automatically switch the electrical test circuit to test the electrical parameters of each phase input terminal 71 and branch output terminal 72 respectively, reduce the number of manual operation steps, and achieve more efficient and safer automated testing.

[0107] It is worth noting that when the data center terminal cabinet test equipment of the present application performs pre-power testing, the power contactors 42 are all kept in the disconnected state, so that the data center terminal cabinet 70 remains unpowered to avoid the risk of electric shock.

[0108] Alternatively, as Figure 1 As shown, in some embodiments, the electrical parameter testing component 60 includes a voltage testing module, a current testing module and a power testing module. The voltage testing module is used to test voltage parameters, the current testing module is used to test current parameters, and the power testing module is used to test power parameters.

[0109] Alternatively, as Figure 1 As shown, in some embodiments, the control component 30 may include an industrial control module 31, a PLC control module 32, and a DC power supply module 33. The DC power supply module 33 is electrically connected to the industrial control module 31 and the PLC control module 32, respectively, for supplying power to the industrial control module 31 and the PLC control module 32. The industrial control module 31 may be implemented as an industrial computer. The industrial control module 31 is provided with a test program, a configuration file, supports touch operation, and has functions such as pause and resume. In addition, the industrial control module 31 is communicatively connected to the continuity test module 11, the insulation test module 21, and the electrical parameter test component 60. By collecting and summarizing the test results of the continuity test module 11, the insulation test module 21, and the electrical parameter test component 60, a test report can be generated. The PLC control module 32 is communicatively connected to the industrial control module 31 and is communicatively connected to the on-off contactor 12, the insulating contactor 22, the power contactor 42, and the load contactor 52, so that the PLC control module 32 can control the on or off of the on-off contactor 12, the insulating contactor 22, the power contactor 42, and the load contactor 52 according to the configuration file of the industrial control module 31, thereby automatically controlling the switching of each test circuit. In this way, the control component 30 of the present application can flexibly set the configuration file, can adapt to different specifications of the data center terminal cabinet 70, and can also realize real-time data collection, analysis, and automatic report generation.

[0110] For example, the industrial control module 31 can be communicatively connected to the continuity test module 11 , the insulation test module 21 , and the current test module via the RS485 protocol.

[0111] Alternatively, as Figure 1 As shown, in some embodiments, the control component 30 further includes a transmission module 34, which is communicatively connected to the industrial control module 31 for outputting a test report.

[0112] Alternatively, as Figure 1 and Figure 4 As shown, in some embodiments, the AC power supply assembly 40 further includes a main switch 43, which is disposed in the power input path 411 and can control the on / off state of the power input path 411. Thus, during pre-power-on testing, the main switch 43 can be turned off to ensure that the power input to the data center header cabinet 70 is disconnected, thereby preventing electric shock.

[0113] Optionally, in some embodiments, the load module 51 is an adjustable load module 51, i.e., the load size of the load module 51 is adjustable. The load module 51 is adjustably connected to the control component 30. Thus, when performing an in-circuit test, the control component 30 can automatically adjust the load size of the load module 51 according to actual test requirements.

[0114] Further, if Figure 6 and Figure 7 As shown, in combination with the data center cabinet test equipment of the present application, the present application also provides a data center cabinet test method, which can inspect and test the data center cabinet. The data center cabinet test method may include the following steps:

[0115] S100, disconnecting each branch circuit breaker of the data center's terminal cabinet; and

[0116] S200, performing a pre-electrical test on the data center cabinet using a pre-electrical test device;

[0117] The step S200 of performing a pre-electrical test on the data center cabinet using a pre-electrical test device includes:

[0118] S210, using the continuity test component of the pre-electrical test device to detect the continuity between each branch output terminal and each phase input terminal of the data center terminal cabinet;

[0119] S220, detecting the phase sequence between the input terminals of each phase path through the on-off test component;

[0120] S230, using the insulation test assembly of the pre-electrical test device to detect the insulation condition between each branch output terminal and the neutral terminal of the data center terminal cabinet; and

[0121] S240. Detect the continuity status between each branch output terminal of the data center cabinet and the phase input terminal corresponding to the branch output terminal through the continuity test component.

[0122] It can be understood that the data center terminal cabinet test method according to the present application can perform pre-electrical testing on the data center terminal cabinet, and detect the on-off condition between each branch output terminal and each phase input terminal through step S210 to ensure that each branch output terminal is not conductive with other phase input terminals. Detect the phase sequence between each phase input terminal of the data center terminal cabinet through step S220 to ensure that each phase input terminal is not conductive with each other. Detect the insulation condition between each branch output terminal and the neutral terminal of the data center terminal cabinet through step S230 to ensure that each branch output terminal is not conductive with the neutral terminal, and detect the disconnection condition between each phase input terminal of the data center terminal cabinet and its corresponding branch output terminal through step S240 to ensure that each phase input terminal and its corresponding branch output terminal are conductive.

[0123] In this way, by conducting pre-electrical testing on the data center terminal cabinet, it can be ensured that the line connection of the data center terminal cabinet is correct, avoiding safety hazards caused by line connection errors.

[0124] Alternatively, as Figure 8 As shown, in some embodiments, step S210 of the data center terminal cabinet testing method of the present application, detecting the continuity between each branch output terminal and each phase input terminal of the data center terminal cabinet by using the continuity test component of the pre-electrical testing device, may include the following steps:

[0125] S211. Controlling, by a PLC control module of the control assembly, to connect a first on-off contactor of the on-off test assembly, wherein the first on-off contactor is located on an on-off test path connected to a first output terminal of a data center terminal cabinet, where the first output terminal is any one of the branch output terminals;

[0126] S212, controlling, through the PLC control module, to turn on each second on-off contactor, wherein the second on-off contactor is located on an on-off test path connected to each of the phase input terminals;

[0127] S213, using the continuity test module of the continuity test assembly, sequentially determining whether the first output terminal and each of the phase input terminals are conductive; and

[0128] S214, repeat the above steps to respectively determine whether each branch output terminal is connected to each phase input terminal.

[0129] For example, taking output terminal 1 as the first output terminal, the various phase input terminals include an A-phase input terminal, a B-phase input terminal, and a C-phase input terminal. According to step S211, the PLC control module controls the first on-off contactor to be turned on, so that the on-off test module is connected to the output terminal 1; according to step S212, the PLC control module controls the second on-off contactor to be turned on, so that the on-off test module is connected to the various phase input terminals; according to step S213, the on-off test module sequentially determines whether the output terminal 1 is connected to the A-phase input terminal, the B-phase input terminal, and the C-phase input terminal. If the output terminal 1 is connected to one or more of the A-phase input terminal, the B-phase input terminal, and the C-phase input terminal, it indicates that the wiring of the output terminal 1 is incorrect; if the output terminal 1 is not connected to the A-phase input terminal, the B-phase input terminal, and the C-phase input terminal, it indicates that the wiring of the output terminal 1 is correct. In this way, according to step S214, by repeating steps S211, S212 and S213, the on-off conditions between each branch output terminal and the phase input terminal of the data center terminal cabinet are tested respectively, so as to ensure that the wiring of the branch output terminal of the data center terminal cabinet is correct.

[0130] Alternatively, as Figure 9 As shown, in some embodiments, step S220 of the data center cabinet testing method of the present application, detecting the phase sequence between each phase input terminal through the continuity test component, may include the following steps:

[0131] S221. Control, through a PLC control module of the control assembly, a first on-off contactor and a second on-off contactor of the on-off test assembly to be turned on, wherein the first on-off contactor is located on an on-off test path connected to a first input terminal of a data center array cabinet, and the second on-off contactor is located on an on-off test path connected to a second input terminal of a data center array cabinet, wherein the first input terminal and the second input terminal are respectively one of the phase input terminals;

[0132] S222, determining in sequence whether the first input terminal and the second input terminal are conductive by the continuity test module of the continuity test assembly; and

[0133] S223: Repeat the above steps to determine whether each phase input terminal is conductive.

[0134] For example, taking the A-phase input terminal and the B-phase input terminal as the first input terminal and the second input terminal, according to step S221, the first on-off contactor and the second on-off contactor are connected through the PLC control module, so that the on-off test module connects the A-phase input terminal and the B-phase input terminal; according to step S222, the on-off test module determines whether the A-phase input terminal and the B-phase input terminal are conductive. If the A-phase input terminal and the B-phase input terminal are conductive, it indicates that the wiring of the A-phase input terminal and the B-phase input terminal is incorrect; if the A-phase input terminal and the B-phase input terminal are not conductive, it indicates that the wiring of the A-phase input terminal and the B-phase input terminal is correct. In this way, by repeating steps S221 and S222, the on-off status between each phase input terminal of the data center terminal cabinet is tested respectively, which can ensure that the wiring of each phase input terminal in the data center terminal cabinet is correct.

[0135] Alternatively, as Figure 10 As shown, in some embodiments, step S230 of the data center terminal cabinet testing method of the present application, detecting the insulation condition between each branch output terminal and the neutral terminal of the data center terminal cabinet by using the insulation testing component of the pre-electrical testing device, may include the following steps:

[0136] S231. Turning on a first insulating contactor and a second insulating contactor through a PLC control module of a control assembly, wherein the first insulating contactor is located on an insulating test path connected to a first output terminal of a data center terminal cabinet, the first output terminal being one of the branch output terminals, and the second insulating contactor is located on an insulating test path connected to a neutral terminal of the data center terminal cabinet;

[0137] S232: Testing the resistance between the first output terminal and the neutral terminal by the insulation testing module of the insulation testing assembly to determine whether the first output terminal and the neutral terminal are insulated; and

[0138] S233. Repeat the above steps to determine whether each branch output terminal is insulated from the neutral terminal.

[0139] For example, taking output 1 as the first output, according to step S231, the PLC control module controls the connection of the first insulating contactor and the second insulating contactor, so that the insulation test module connects output 1 and the neutral terminal respectively; according to step S232, the insulation test module tests the resistance value between output 1 and the neutral terminal. If the resistance value between output 1 and the neutral terminal is too small and does not meet the insulation requirements, it means that output 1 is short-circuited with the neutral terminal, and the wiring of output 1 or the neutral terminal is incorrect; if the resistance value between output 1 and the neutral terminal is too large and meets the insulation requirements, it means that the output 1 and the neutral terminal are insulated, and the wiring of output 1 or the neutral terminal is correct. In this way, according to step S233, by repeating steps S231 and S232, the insulation between each branch output terminal and the neutral terminal of the data center terminal cabinet is tested respectively, which can ensure that the wiring of each branch output terminal and the neutral terminal of the data center terminal cabinet is correct.

[0140] Alternatively, as Figure 11 As shown, in some embodiments, step S240 of the data center terminal cabinet testing method of the present application, detecting the continuity between each branch output terminal of the data center terminal cabinet and the phase input terminal corresponding to the branch output terminal through the continuity test component, includes the steps of:

[0141] S241. Turn on each branch circuit breaker of the data center's terminal cabinet;

[0142] S242. Controlling, by a PLC control module of the control assembly, to connect a first on-off contactor of the on-off test assembly, wherein the first on-off contactor is located on an on-off test path connected to a first output terminal of a data center terminal cabinet, where the first output terminal is any one of the branch output terminals;

[0143] S243. Control, through the PLC control module, turning on a second on-off contactor, wherein the second on-off contactor is located on an on-off test path connected to a first input terminal of a data center cabinet, where the first input terminal is one of the phase input terminals corresponding to the first output terminal.

[0144] S244, determining whether the first output terminal and the first input terminal are conductive by the continuity test module of the continuity test component; and

[0145] S245 , repeat the above steps to respectively determine whether each branch output terminal is conductive with the phase input terminal corresponding to the branch output terminal.

[0146] For example, taking output 1 as the first output and phase A input as the first input, according to step S241, each branch circuit breaker in the data center's terminal cabinet is manually connected to connect each phase input with the corresponding branch output. According to step S242, the PLC control module controls the connection of the first on-off contactor to connect the on-off test module to output 1. According to step S243, the PLC control module controls the connection of the second on-off contactor to connect the on-off test module to phase A input. According to step S244, the on-off test module determines whether output 1 is connected to phase A input. If so, it indicates that the connection between output 1 and phase A input is correct. If disconnected, it indicates that the connection between output 1 and phase A input is incorrect. In this way, according to step S245, by repeating the above steps S242, S243 and S244, each branch output terminal of the data center terminal cabinet and its corresponding phase input terminal are tested respectively to see whether they are conductive, thereby ensuring that the wiring of each branch output terminal of the data center terminal cabinet and its corresponding phase input terminal is correct.

[0147] In summary, the data center terminal cabinet testing method of the present application can control the connection and disconnection of the on-off contactor and the insulating contactor through the control component, and can automatically realize the pre-electrical testing of the data center terminal cabinet, which can reduce the steps of manual operation, improve the testing efficiency, and make the testing process safer.

[0148] Further, if Figure 12 and Figure 13 As shown, in some embodiments, the data center cabinet testing method of the present application further includes the following steps:

[0149] S300, connecting each branch circuit breaker of the data center's terminal cabinet; and

[0150] S400, perform an electrical test on the data center cabinet using an electrical test device;

[0151] The step S400 of performing an electrical test on the data center cabinet using an electrical test device includes:

[0152] S410, using the voltage test module of the electrical parameter test assembly to test the phase-to-phase voltage between each phase input terminal and the neutral terminal;

[0153] S420: Using the voltage testing module, respectively test the line voltage between each phase input terminal; and

[0154] S430 , respectively testing the output current and output power of the branch output end through the current testing module and the power testing module of the electrical parameter testing component.

[0155] It can be understood that the data center terminal cabinet test method according to the present application can be used to perform an electrical test on the data center terminal cabinet. By detecting the phase-to-phase voltage between each phase input terminal and the neutral terminal and the line-to-line voltage between each phase input terminal respectively through step S410 and step S420, it can be determined whether the three-phase voltage system of the data center terminal cabinet is balanced. If the phase-to-phase voltage or the line-to-line voltage deviates from the normal range, it means that the data center terminal cabinet may have insulation degradation or short circuit risks. The output current and output strategy can reflect the output status of the data center terminal cabinet. If the current is too high, it means that the data center terminal cabinet may have problems such as short circuit or equipment failure. If the output current is too low, it means that the data center terminal cabinet may have a line connection problem; if the output power fluctuates abnormally, it means that the data center terminal cabinet may have equipment aging problems or the circuit design of the data center terminal cabinet is defective. By detecting the output current and output power of each branch output terminal respectively through step S430, the line inspection and aging test of the data center terminal cabinet can be realized.

[0156] Alternatively, as Figure 14 As shown, in some embodiments, step S410 of the data center cabinet testing method of the present application, the step of testing the phase-to-phase voltage between each phase input terminal and the neutral terminal by the voltage testing module of the electrical parameter testing component includes:

[0157] S411. Controlling, through a PLC control module of a control assembly, to turn on a first power contactor, wherein the first power contactor is located on a power output path connected to a first input terminal of a data center cabinet, the first input terminal being any one of the plurality of phase input terminals.

[0158] S412. Test, by the voltage testing module, the voltage between the first output terminal and the neutral terminal, wherein the first output terminal is one of the branch output terminals corresponding to the first input terminal, and the voltage between the first output terminal and the neutral terminal is the phase-to-phase voltage between the first input terminal and the neutral terminal; and

[0159] S413. Repeat the above steps to test the phase-to-phase voltage between each phase input terminal and the neutral terminal respectively.

[0160] For example, taking the A-phase input terminal as the first input terminal, according to step S411, the PLC control module controls the connection of the first power contactor, connecting the AC power module to the A-phase input terminal; according to step S412, the voltage between the 1-way output terminal corresponding to the A-phase input terminal and the neutral terminal is tested by the voltage testing module, thereby obtaining the phase-to-phase voltage between the A-phase input terminal and the neutral terminal. If the measured phase-to-phase voltage is within the normal range, it indicates that the wiring of the A-phase input terminal does not have insulation aging or short circuit problems; if the measured phase-to-phase voltage deviates from the normal range, it indicates that the wiring of the A-phase input terminal may have insulation aging or short circuit problems. In this way, according to step S413, by repeating steps S411 and S412, the phase-to-phase voltage between each phase input terminal and the neutral line can be tested separately, thereby determining whether the wiring of each phase input terminal has insulation aging or short circuit problems.

[0161] Alternatively, as Figure 15 As shown, in some embodiments, step S420 of the data center cabinet testing method of the present application, the step of testing the line voltage between each phase input terminal by the voltage testing module includes:

[0162] S421. Controlling, through a PLC control module of a control component, to connect a first power contactor and a second power contactor, wherein the first power contactor and the second power contactor are respectively located on a power output path connected to a first input terminal and a second input terminal of a data center terminal cabinet, the first input terminal and the second input terminal being any two of a plurality of phase input terminals, and the first input terminal and the second input terminal having different phases;

[0163] S422. Test, by the voltage testing module, a voltage between a first output terminal and a second output terminal, wherein the first output terminal is one of the branch output terminals corresponding to the first input terminal, the second output terminal is one of the branch output terminals corresponding to the second input terminal, and the voltage between the first output terminal and the second output terminal is a line-to-line voltage between the first input terminal and the second input terminal; and

[0164] S423. Repeat the above steps to test the line voltage between the input terminals of each phase.

[0165] For example, using the A-phase input terminal and the B-phase input terminal as the first input terminal and the second input terminal, according to step S421, the PLC control module controls the connection of the first power contactor and the second power contactor, so that the AC power module is connected to the A-phase input terminal and the B-phase input terminal. According to step S422, the voltage test module tests the voltage between the 1-way output terminal and the 2-way output terminal corresponding to the A-phase input terminal and the B-phase input terminal, respectively, to obtain the line-to-line voltage between the A-phase input terminal and the B-phase input terminal. If the measured line-to-line voltage is within the normal range, it indicates that the wiring between the A-phase input terminal and the B-phase input terminal does not have insulation aging or short circuit problems. If the measured line-to-line voltage deviates from the normal range, it indicates that the wiring between the A-phase input terminal and the B-phase input terminal does have insulation aging or short circuit problems. Thus, according to step S423, by repeating the above steps S421 and S422, the line-to-line voltage between each phase input terminal can be measured respectively, thereby determining whether the wiring of each phase input terminal has insulation aging or short circuit problems.

[0166] Alternatively, as Figure 16 As shown, in some embodiments, step S430 of the data center cabinet testing method of the present application, the step of testing the output current and output power of the branch output end respectively by the current testing module and the power testing module of the electrical parameter testing component includes:

[0167] S431. Control, through a PLC control module of a control component, connecting a first power contactor and a first load contactor, wherein the first power contactor is located on a power output path connected to a first input terminal of a data center terminal cabinet, the first input terminal being any one of a plurality of phase input terminals, and the first load contactors are respectively located on load input paths connected to a first output terminal of a data center terminal cabinet, the first output terminal being one of the branch output terminals corresponding to the first input terminal;

[0168] S432: Testing the output current of the first output end by the current testing module;

[0169] S433, testing the output power of the first output end through the power testing module; and

[0170] S434: Repeat the above steps to test the output current and output power of each branch output terminal respectively.

[0171] Exemplarily, taking the A-phase input terminal as the first input terminal and the 1-way output terminal as the first output terminal as an example, according to step S431, the PLC control module is used to control the connection of the first power contactor and the first load contactor, so that the AC power supply module is connected to the A-phase input terminal and the load module is connected to the 1-way output terminal; according to step S432, the output current of the 1-way output terminal is tested by the current testing module. If the measured output current is too high, it means that there may be a short circuit problem in the wiring of the 1-way output terminal. If the measured output current is too low, it means that there may be a line virtual connection problem in the wiring of the 1-way output terminal. If the measured output current is within the normal range, it means that there is no short circuit or line virtual connection problem in the wiring of the 1-way output terminal; according to step S433, the output power of the 1-way output terminal is tested by the power testing module. If the measured output power has abnormal fluctuations, it means that there is an aging problem in the wiring of the 1-way output terminal or there is a defect in the circuit design of the 1-way output terminal. If the measured output power is within the normal range, it means that there is no aging problem in the wiring of the 1-way output terminal and the circuit design is reasonable. In this way, according to step S434, by repeating the above steps S431, S432 and S433, the output current and output power of each branch output end can be detected respectively to ensure that the wiring of each branch output end does not have problems such as aging, short circuit or false connection.

[0172] In summary, the data center terminal cabinet testing method of the present application can control the connection and disconnection of the power contactor and the load contactor through the control component, can automatically realize the electrical testing of the data center terminal cabinet, can reduce the steps of manual operation, and has higher testing efficiency and a safer testing process.

[0173] It is worth noting that some data center terminal cabinets include intelligent modules that can display phase-to-phase voltage, line-to-line voltage, output current and output power. Therefore, the data center terminal cabinet testing method of the present application can also connect the electrical parameter testing component to the intelligent module, and compare the phase-to-phase voltage, line-to-line voltage, output current and output power obtained by the test with the phase-to-phase voltage, line-to-line voltage, output current and output power displayed by the data center terminal cabinet itself to determine whether there are problems such as aging or short circuit in the wiring of the data center terminal cabinet.

[0174] In particular, if Figure 17 As shown, in some embodiments, the data center cabinet testing method of the present application further includes the steps of:

[0175] S500, generating a test report through the industrial control module of the control component; and

[0176] S600: Output a test report through the transmission module of the control component.

[0177] In this way, according to step S500, the industrial control module can collect the test results of the pre-electrical test in step S200 and the electrical test in step S400, and produce a test report. According to step S600, the test report generated by the industrial control module can be output through the transmission module to save and review the test results.
