[0020] In order to more clearly illustrate the technical solutions in the present disclosure or the related art, the drawings needed to be used in the embodiments or the related art description will be briefly introduced. Obviously, the drawings in the following description are only embodiments of the present disclosure, and other drawings can be obtained by those skilled in the art without any creative effort based on these drawings.

[0022] Figure 2 A structural schematic diagram of a card seat detection area provided by an embodiment of the present disclosure is shown in the figure.
[0023] Figure 3 A structural schematic diagram of a free detection area provided by an embodiment of the present disclosure is shown in the figure. DETAILED DESCRIPTION
[0024] In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below with reference to specific embodiments and drawings.
[0025] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should be understood as the general meanings understood by those skilled in the art to which the present disclosure belongs. The terms "first", "second", and similar terms used in the embodiments of the present disclosure do not represent any order, number, or importance, but are only used to distinguish different components. The terms "include", "contain", and similar terms mean that the elements or objects before the terms cover the elements or objects listed after the terms and their equivalents, and do not exclude other elements or objects. The terms "connect" or "connected" and similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms "up", "down", "left", "right", and the like are only used to represent relative positional relationships, and when the absolute positions of the described objects change, the relative positional relationships may also change accordingly.
[0026] In pumped storage power plants, due to the frequent need for unit start-stop operation, the secondary components often have poor contact, abnormal operation and other faults. The causes of the abnormal operation of the secondary components are uncertain, and the faults are hidden, which need a large number of repeated tests for analysis. A large number of repeated tests require more human and time costs. The traditional manual detection time includes time-consuming searching for materials (power supply, cable, etc.), wiring production, wiring connection, etc.; each test needs to be confirmed one hundred times, and manual pressure and stop are required, and the wiring is repeatedly disassembled and assembled, which is low in efficiency.
[0027] In view of this, the present disclosure provides a testing device for electromagnetic switching devices, which includes a support rail, a card slot testing area, a power supply module, and a control module. At least one card slot testing area is disposed on the support rail, and the card slot testing area includes at least one card slot testing position for connecting the electromagnetic switching device to be tested. The power supply module connects the card slot testing position and the control module. The card slot testing position is connected to the control module and is used to receive action test commands sent by the control module to the electromagnetic switching device to be tested, and to send feedback signals returned by the electromagnetic switching device to the control module, so that the control module completes the testing of the electromagnetic switching device based on the feedback signals. This enables the testing of electromagnetic switching devices, providing quantitative data for defect analysis. It can also effectively detect components with family-related defects and can automatically detect hidden defect states of components during factory inspection, incoming goods acceptance, and spare parts requisition stages, achieving effective selection and greatly improving efficiency.
[0028] Figure 1 A schematic diagram of the structure of a detection device for an electromagnetic switching device provided in an embodiment of this disclosure; Figure 2 This is a schematic diagram of the structure of a card slot detection area provided in an embodiment of the present disclosure; Figure 3 This is a schematic diagram of the structure of a free detection region provided in an embodiment of this disclosure.
[0029] like Figures 1-3 As shown, the detection device includes:
[0030] Support rails, for example Figure 2 and Figure 3 The guide rails 1 and 2 are used to facilitate the layout of the card holder detection area, which helps to realize the rapid insertion and removal of the electromagnetic switching device to be tested.
[0031] At least one card slot detection area 102 (e.g.) Figure 2 Group 1, Group 2, Group 3, and Group 4 are set on the support guide rail. The card holder detection area 102 includes at least one card holder detection position, which is used to connect the electromagnetic switching device 200 to be tested.
[0032] The system includes a power module 101 and a control module 103. The power module 101 is connected to the card slot detection position and the control module 103. The card slot detection position is connected to the control module 103 and is used to receive the action test command sent by the control module 103 to the electromagnetic switch device 200 under test, and to send the feedback signal returned by the electromagnetic switch device 200 under test to the control module 103, so that the control module 103 can complete the detection of the electromagnetic switch device 200 under test according to the feedback signal.
[0033] Here, the control module can be a Siemens LOGO! 24RCE general logic module, or other modules can also be used. The LOGO! 24RCE general logic module has a display unit, is used with two DM1624R extension modules, has a running voltage of 24VDC, and contains 24 digital inputs and 20 relay outputs. It should be noted that the control module 10 sends test instructions, accepts feedback signals, and detection can be implemented using related technologies, and a person skilled in the art can flexibly select based on related technologies, and the present disclosure does not limit this.
[0034] Using the control module to input the action test instruction can realize batch continuous action testing, greatly saving the time cost and labor cost of testing.
[0035] In some embodiments, as shown in Figure 2 and Figure 3 , the card seat detection position includes power contacts (such as A1 and A2) and pairs of control contacts (such as contacts 44 and 41, contacts 34 and 31, contacts 24 and 31, contacts 14 and 11, etc.); wherein the power contacts are connected to the power module; the control contacts are connected to the control module.
[0036] By setting power contacts and control contacts in the card seat detection position, the electromagnetic switch device to be detected can be directly inserted into the type-matched card seat detection position without additional wiring, which can greatly improve the detection effect. It should be noted that for different types of electromagnetic switch devices to be detected, the number and position of the control contacts in the card seat detection position can be adjusted to correspond to the electromagnetic switch device to be detected. In this way, the card seat detection position can be adapted to multiple types of electromagnetic switch devices to be detected, increasing the applicability.
[0037] In some embodiments, as shown in Figure 2 and Figure 3 , the power contacts include first power contacts A1 and second power contacts A2; wherein the first power contacts A1 of adjacent card seat detection positions are conducted through first connecting lines; the second power contacts A2 of adjacent card seat detection positions are conducted through second connecting lines. In this way, the power module can provide a preset power supply to multiple card seat detection positions in the same card seat detection area 102. It should be noted that the preset power supply can be 220VAC, 220DC, and 24VDC, etc., and the present disclosure does not limit this.
[0038] In some embodiments, in order to detect different preset power supplies of the electromagnetic switch device to be detected, a power supply selection module (such as SW1 in Figure 2 is provided between the power module 101 and the card seat detection position. Figure 3The power selection module (SW2, SW3) is used to control the preset voltage of the card slot detection position and the control module 103.
[0039] In some embodiments, such as Figure 2 As shown, each pair of control contacts includes a first control contact (e.g., 44, 34, 24, 14, etc.) and a second control contact (e.g., 41, 31, 21, 11, etc.); any first control contact is connected to one of its two adjacent first control contacts; any second control contact is connected to one of its two adjacent second control contacts. Here, adjacent first control contacts and adjacent second control contacts may belong to the same card slot detection position or to different card slot detection positions, and this disclosure does not limit this.
[0040] This method allows control contacts in the same card slot detection area to share a single control signal line, significantly reducing the number of control signal lines required. For example, if all the electromagnetic switching devices under test in the same card slot detection area are functioning normally, each control contact can conduct, allowing the control signal line to pass through. The control module can then determine that each electromagnetic switching device 200 under test is functioning normally and continue detection. If any electromagnetic switching device 200 under test is malfunctioning, the control signal line will not pass through, and the control module 103 can determine that a fault exists and stop detection.
[0041] In some embodiments, the same card slot detection area 102 is used to detect the same type of electromagnetic switching device 200 to be tested; different card slot detection areas 102 are used to detect the same or different types of electromagnetic switching devices 200 to be tested. In other words, multiple card slot detection areas 102 can be set up to detect the same type of electromagnetic switching device 200 to be tested, and the same card slot detection area 102 can only detect the same type of electromagnetic switching device 200 to be tested. This approach facilitates the wiring and connection of the card slot detection positions within the card slot detection area 102.
[0042] In some embodiments, such as Figure 3As shown, the free detection area further comprises at least one free detection position, and the free detection position comprises a power supply contact (e.g., A1 and A2) and a pair of control contacts (e.g., contact 44 and 41, contact 34 and 31, contact 24 and 31, contact 14 and 11, etc.).
[0043] In some embodiments, as shown in Figure 3 As shown, the free detection area comprises at least one free detection position, and the free detection position comprises a power supply contact (e.g., A1 and A2) and a pair of control contacts (e.g., contact 44 and 41, contact 34 and 31, contact 24 and 31, contact 14 and 11, etc.).
[0044] Here, as shown in Figure 3 As shown, the pair of control contacts comprises a first control contact (e.g., 44, 34, 24, 14, etc.) and a second control contact (e.g., 41, 31, 21, 11, etc.). The free detection area is configured with at least one first control line (e.g., I19, I10), and the first control line is used to connect the first control contact of any free detection position. In other words, the first control line has good adaptability and can be connected to any free detection position, and is suitable for connecting any number of electromagnetic switch devices 200 in the free detection area.
[0045] Correspondingly, the free detection area is configured with a second control line (e.g., I11), and the second control line is used to connect the second control contact (e.g., 41, 31, 21, 11, etc.) of a preset free detection position, for example Figure 3 Figure 3 the leftmost second control contact 41 in
[0046] In some embodiments, the free detection area is further configured with a first delay signal line and a second delay signal line (e.g., I14-I23), and the first delay signal line and the second delay signal line are respectively connected to the two control contacts of the free detection position. With the first delay signal line and the second delay signal line, the delay performance of the electromagnetic switch device 200 in each free detection position can be detected.
[0047] In some embodiments, the first delay signal line is connected to a delay switch (e.g., K7), which is used to control the connection state of the first delay signal line. By using the delay switch, preset detection of the electromagnetic switch device 200 can be achieved, such as delay detection or continuous action detection.
[0048] It should be understood by those of ordinary skill in the art that the above discussion of any of the embodiments is merely exemplary and is not intended to suggest the scope of the disclosure (including the claims) is limited to these examples; the embodiments above or technical features among different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes to the aspects of the embodiments of the disclosure as described above, which are not provided in detail for the sake of brevity.

Accordingly, any one of the above-mentioned embodiments or technical features among different embodiments can be combined, the steps can be implemented in any order, and there are many other changes to the aspects of the embodiments of the disclosure as described above, which are not provided in detail for the sake of brevity, and any omission, modification, equivalent replacement, improvement, etc. made within the spirit and principles of the embodiments of the present disclosure shall be included in the protection scope of the present disclosure.
