In order to ensure that the industrial frequency conversion speed control cabinet can be used normally after leaving the factory, the industrial frequency conversion speed control cabinet needs to be subjected to high voltage test and functional test before leaving the factory. Among them, the high voltage test is used to detect whether the circuit connection of each component in the industrial frequency conversion speed control cabinet is normal, and the functional test is used to detect whether the function of the industrial frequency conversion speed control cabinet is normal.

After completing the high voltage test, the corresponding functional test adapter is selected to connect with the industrial frequency conversion speed control cabinet to perform functional test on the industrial frequency conversion speed control cabinet.

[0058] As mentioned above, currently when performing high voltage test and functional test on industrial frequency conversion speed control cabinet, firstly manually short-circuit each circuit to be tested to perform high voltage test, and manually remove the short-circuit wires of each circuit to be tested after the high voltage test, and then manually connect the test adapter to the industrial frequency conversion speed control cabinet to perform functional test, and manually remove the test adapter after the functional test. It can be seen that, when performing high voltage test and functional test on industrial frequency conversion speed control cabinet, at least two manual wirings are required, and each manual wiring takes a long time, which leads to low efficiency of high voltage test and functional test on industrial frequency conversion speed control cabinet.

[0059] In the embodiment of the present invention, the two connectors of the first multi-pin connector are respectively connected to the high-voltage test point and the high-voltage tester on the industrial frequency conversion speed control cabinet, and the two connectors of the second multi-pin connector are respectively connected to the functional test point and the test adapter on the industrial frequency conversion speed control cabinet. The controller can close or disconnect the first multi-pin connector and the second multi-pin connector by controlling the first cylinder and the second cylinder, thereby realizing the short circuit of the circuit to be tested and the connection of the functional test circuit in the industrial frequency conversion speed control cabinet, and then the industrial frequency conversion speed control cabinet can be subjected to high-voltage test and functional test. Since the user only needs to perform wiring once to connect the first multi-pin connector and the second multi-pin connector to the industrial frequency conversion speed control cabinet, the number of manual wiring is reduced, thereby improving the efficiency of high-voltage test and functional test on the industrial frequency conversion speed control cabinet.

[0060] The industrial variable frequency speed control cabinet testing device, method and system provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0061] like Figure 1 As shown, an embodiment of the present invention provides an industrial variable frequency speed control cabinet testing device 10, comprising: a controller 101, a first multi-pin connector 102, a second multi-pin connector 103, a first cylinder 104 and a second cylinder 105;

[0062] The first multi-pin connector 102 includes a first connector and a second connector that can be matched and connected, at least two pins on the first connector are connected to the high-voltage test point on the industrial frequency conversion cabinet 20, and at least two pins on the second connector are short-circuited with each other and connected to the high-voltage tester 30;

[0063] The second multi-pin connector 103 includes a third connector and a fourth connector that can be matched and connected, at least one pin on the third connector is connected to a functional test point on the industrial frequency conversion cabinet 20, and at least one pin on the fourth connector is connected to at least one test adapter 40;

[0064] The controller 101 is used to control the first cylinder 104 to drive the first joint and the second joint to move relative to each other so that the first multi-pin connector 102 is closed, and control the second cylinder 105 to drive the third joint and the fourth joint to move relative to each other so that the second multi-pin connector 103 is disconnected, so as to perform a high voltage test on the industrial frequency conversion speed control cabinet 20;

[0065] The controller 101 is further used to control the first cylinder 104 to drive the first connector and the second connector to move relative to each other so that the first multi-pin connector 102 is disconnected, and control the second cylinder 105 to drive the third connector and the fourth connector to move relative to each other so that the second multi-pin connector 103 is closed, so as to perform a functional test on the industrial frequency conversion cabinet 20.

[0066] In the embodiment of the present invention, one connector of the first multi-pin connector 102 is connected to the high-voltage test point on the industrial variable frequency speed control cabinet 20, and at least two pins on another connector of the first multi-pin connector 102 are short-circuited and connected to the high-voltage tester 30. When the controller 101 controls the first cylinder 104 to drive the two connectors of the first multi-pin connector 102 to close, the short circuit of each circuit to be tested in the industrial variable frequency speed control cabinet is realized, and the industrial variable frequency speed control cabinet 20 can be tested with a high voltage. One connector of the second multi-pin connector 103 is connected to the functional test point on the industrial variable frequency speed control cabinet 20, and another connector of the second multi-pin connector 103 is connected to at least one test adapter 40. When the controller 101 controls the second cylinder 105 to drive the two connectors of the second multi-pin connector 103 to close, the industrial variable frequency speed control cabinet 20 is connected to each test adapter 40, and the industrial variable frequency speed control cabinet 20 can be tested with a functional test. It can be seen that under the control of the controller 101, automatic wiring and automatic switching of high-voltage testing and functional testing of the industrial frequency conversion speed control cabinet 20 can be realized. The user only needs to connect the first multi-pin connector 102 and the second multi-pin connector 103 to the industrial frequency conversion speed control cabinet 20 once. Since the number of manual wiring is reduced, the efficiency of high-voltage testing and functional testing of the industrial frequency conversion speed control cabinet 20 can be improved.

[0067] In the embodiment of the present invention, the multi-pin connector includes a male head and a female head, the male head includes a plurality of pins, the female head includes a plurality of pins, and after the male head and the female head are connected and matched, each pin on the male head is connected to a corresponding pin on the female head. In the first multi-pin connector 102, when the first connector is a male head, the second connector is a female head, and when the first connector is a female head, the second connector is a male head. In the second multi-pin connector 103, when the third connector is a male head, the fourth connector is a female head, and when the third connector is a female head, the fourth connector is a male head.

[0068] Optionally, in Figure 1 Based on the industrial variable frequency speed control cabinet test device 10 shown in FIG. Figure 2As shown, the first insulating connecting plate 106 is provided with a first mounting plate 107, two parallel first guide rails 108 and a first cylinder 104. The first cylinder 104 can drive the second mounting plate 109 to move along the two first guide rails 108. The first joint 1021 is connected to the first mounting plate 107, and the second joint 1022 is connected to the second mounting plate 109. When the controller 101 controls the first cylinder 104 to drive the second mounting plate 109 to move in a direction close to the first mounting plate 107, the distance between the first joint 1021 and the second joint 1022 is reduced, and finally the first joint 1021 and the second joint 1022 are connected, so as to achieve the closing of the first multi-pin connector 102. When the controller 101 controls the first cylinder 104 to drive the second mounting plate 109 to move in a direction away from the first mounting plate 107, the distance between the first joint 1021 and the second joint 1022 is increased, and finally the first joint 1021 and the second joint 1022 are separated, so as to achieve the disconnection of the first multi-pin connector 102.

[0069] like Figure 2 As shown, the second insulating connecting plate 110 is provided with a third mounting plate 111, two parallel second guide rails 112 and a second cylinder 105, the second cylinder 105 can drive the fourth mounting plate 113 to move along the two second guide rails 112, the third joint 1031 is connected to the third mounting plate 111, and the fourth joint 1032 is connected to the fourth mounting plate 113. When the controller 101 controls the second cylinder 104 to drive the fourth mounting plate 113 to move in a direction close to the third mounting plate 111, the distance between the third joint 1031 and the fourth joint 1032 is reduced, and finally the third joint 1031 and the fourth joint 1032 are connected, so as to achieve the closing of the second multi-pin connector 103. When the controller 101 controls the second cylinder 104 to drive the fourth mounting plate 113 to move in a direction away from the third mounting plate 111, the distance between the third joint 1031 and the fourth joint 1032 is increased, and finally the third joint 1031 and the fourth joint 1032 are separated, so as to achieve the disconnection of the second multi-pin connector 103.

[0070] In the embodiment of the present invention, the connectors included in the first multi-pin connector 102 and the second multi-pin connector 103 are arranged on a mounting plate made of insulating material, and the mounting plate is connected to the insulating connecting plate, so as to avoid leakage of the first multi-pin connector 102 and the second multi-pin connector 103, and ensure the safety of the test process. In addition, parallel guide rails are arranged on the insulating connecting plate, and the cylinder can drive the mounting plate to move linearly along the parallel guide rails, so as to ensure that the first multi-pin connector 102 and the second multi-pin connector 103 can be closed and disconnected normally, thereby ensuring that the test process can proceed normally.

[0071] Optionally, in Figure 1 Based on the industrial variable frequency speed control cabinet test device 10 shown in FIG. Figure 3As shown, the industrial variable frequency speed control cabinet testing device 10 further comprises: at least two first relays 114;

[0072] One of the terminals of each first relay 114 is short-circuited with each other and connected to the high voltage tester 30;

[0073] For each first relay 114 , another terminal of the first relay 114 is connected to one of the circuits to be tested formed after the first multi-pin connector 102 is closed, and different first relays 114 are connected to different circuits to be tested;

[0074] The controller 101 is further used to control one of the first relays 114 to close and the other first relays 114 to open in sequence after the first multi-pin connector 102 is closed and the second multi-pin connector 103 is opened, and to control the high-voltage tester 30 to output a corresponding high voltage to perform a high-voltage test on the circuit to be tested connected to the closed first relay 114.

[0075] In the embodiment of the present invention, by short-circuiting some or all of the pins on the second connector 1022, multiple circuits to be tested will be formed after the first multi-pin connector 102 is closed, and the voltage required for each circuit to be tested is different when performing a high-voltage test. Therefore, it is necessary to perform a high-voltage test on each circuit to be tested separately, and when a circuit to be tested is tested at a high voltage, other circuits to be tested need to be grounded. The high-voltage tester 30 is connected to each first relay 114, and each first relay 114 is connected to a corresponding circuit to be tested. The controller 101 controls each first relay 114 to close in turn and ensures that only one first relay 114 is closed at the same time, and controls the high-voltage tester 30 to output a corresponding high voltage to perform a high-voltage test on the circuit to be tested connected to the first relay 114 in a closed state.

[0076] For example, the industrial frequency conversion cabinet 20 includes three circuits to be tested, the test voltage required for the first circuit to be tested is 690V, the test voltage required for the second circuit to be tested is 380V, and the test voltage required for the third circuit to be tested is 220V. First, the controller 101 controls the first relay 114 connected to the first circuit to be tested to be closed, while the other two first relays 114 are disconnected, and then the controller 101 controls the high-voltage tester 30 to output a high voltage of 690V to perform a high-voltage test on the first circuit to be tested; then, the controller 101 controls the first relay 114 connected to the second circuit to be tested to be closed, while the other two first relays 114 are disconnected, and then the controller 101 controls the high-voltage tester 30 to output a high voltage of 380V; then, the controller 101 controls the first relay 114 connected to the third circuit to be tested to be closed, while the other two first relays 114 are disconnected, and then the controller 101 controls the high-voltage tester 30 to output a high voltage of 220V.

[0077] In an embodiment of the present invention, each circuit to be tested is connected to a first relay 114, and the controller 101 controls the closure of each first relay 114 in turn, and controls the high-voltage tester 30 to output a high voltage of corresponding magnitude, thereby realizing automatic switching of each circuit to be tested for high-voltage testing without manual switching. On the one hand, it can reduce the labor intensity of personnel performing high-voltage testing and ensure the safety of testers. On the other hand, it can further improve the efficiency of high-voltage testing and functional testing of industrial frequency conversion cabinets.

[0079] For each second relay 115 , one terminal of the second relay 115 is connected to a test adapter 40 , and another terminal of the second relay 115 is connected to at least one pin on the fourth connector 1032 ;

[0080] The controller 101 is further used to control one of the second relays 115 to close and the other second relays 115 to disconnect in sequence after the first multi-pin connector 102 is disconnected and the second multi-pin connector 203 is closed, and control the test adapter 40 connected to the closed second relay 115 to perform a functional test on the industrial frequency conversion cabinet 20.

[0081] In an embodiment of the present invention, the industrial frequency conversion speed regulation cabinet 20 includes multiple options to be functionally tested, and the functional test points for functionally testing each option are connected to the second multi-pin connector 103. The second multi-pin connector 103 is connected to multiple second relays 115. The controller 101 controls each second relay 115 to be closed, and can connect the corresponding test adapter 40 to the option in turn, and then perform functional testing on the option through the test adapter 40, thereby automatically switching to each option for functional testing without manual operation, thereby further improving the efficiency of functional testing of the industrial frequency conversion speed regulation cabinet 20.

It can be seen that the scanning gun scanning the product bar code of the industrial variable frequency speed control cabinet 20 enables the controller 101 to determine the product model of the industrial variable frequency speed control cabinet 20, and then the controller 101 can use the corresponding test strategy and test sequence to perform high voltage testing and functional testing on the industrial variable frequency speed control cabinet 20, so as to realize the fully automatic high voltage testing and functional testing of the industrial variable frequency speed control cabinet 20.

[0087] It should be noted that the controller 101 in the above-mentioned embodiments can be implemented by PLC.

[0088] like Figure 5 As shown, an embodiment of the present invention provides an industrial variable frequency speed control cabinet testing method based on any one of the industrial variable frequency speed control cabinet testing devices 10 provided in the above embodiments, and the method may include the following steps:

[0089] Step 501: Use the controller 101 to control the first cylinder 104 to drive the first joint and the second joint to move relative to each other so that the first multi-pin connector 102 is closed, and control the second cylinder 105 to drive the third joint and the fourth joint to move relative to each other so that the second multi-pin connector 103 is disconnected, so as to perform a high voltage test on the industrial variable frequency speed control cabinet 20;

[0090] Step 502: Use the controller 101 to control the first cylinder 104 to drive the first connector and the second connector to move relative to each other so that the first multi-pin connector 102 is disconnected, and control the second cylinder 105 to drive the third connector and the fourth connector to move relative to each other so that the second multi-pin connector 103 is closed, so as to perform a functional test on the industrial frequency conversion cabinet 20.

[0091] In the embodiment of the present invention, the controller 101 is used to control the action of the first cylinder 104 and the second cylinder 105, which can drive the first multi-pin connector 102 and the second multi-pin connector 103 to open or close, so that the circuit for high-voltage testing and the circuit for functional testing are closed in sequence. The user only needs to connect the first multi-pin connector 102 and the second multi-pin connector 103 to the industrial frequency conversion speed regulation cabinet 20 by wiring in sequence at the beginning of the test. There is no need to re-wire during the test. Since the number of manual wiring by the user is reduced, the efficiency of high-voltage testing and functional testing of the industrial frequency conversion speed regulation cabinet 20 can be improved.

There is no need to manually switch different circuits to be tested for high-voltage testing, which further improves the efficiency of high-voltage testing of the industrial frequency conversion cabinet 20.
