[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the present invention provides a medium and low voltage switch cabinet detection device, comprising a detection cabinet 1, in which a plurality of detection modules 2 are detachably installed in partitions.

[0051] The detection module 2 generally includes a loop resistance detection module, a mechanical property detection module, a ground resistance detection module, a partial discharge detection module, a power frequency withstand voltage detection module, and an insulation resistance detection module. Each detection module 2 performs corresponding detection items respectively.

[0052] When one of the detection modules 2 needs to be repaired, the detection module 2 is taken out from the detection cabinet 1 and repaired, while the other detection modules 2 perform detection work normally. This not only meets the multi-project detection requirements of medium and low voltage switch cabinets, but also does not delay the detection process of other detection modules 2 when a certain detection module 2 needs to be repaired.

[0053] In the present invention, a main control board 3 is embedded on the outer wall of the detection cabinet 1, and a plurality of mounting plates 4 are installed on the side of the main control board 3 close to the inside of the detection cabinet 1. An internal terminal 5 is installed on each mounting plate 4. The internal terminal 5 is connected to an external terminal 6 through a connecting cable. The external terminal 6 penetrates the main control board 3 and extends to the outside of the main control board 3, so as to be plugged in the test cable outside the detection cabinet 1;

[0054] A wiring base 7 is installed on the mounting plate 4. One end of the wiring base 7 corresponds to the detection module 2 one by one and is connected through a wire 8, and the other end is for the internal wiring head 5 to be plugged in.

[0055] When the detection module 2 is detecting, the test cable on the switch cabinet is plugged into the external terminal 6, and is connected to the detection module 2 through the connecting cable, the internal terminal 5, the terminal block 7, and the wire 8 in sequence, thereby realizing detection.

[0056] In practical applications, if the testing party does not know the specific testing module 2 to be repaired, it is possible that the test cable is plugged into the external terminal 6 of the testing module 2. At this time, since the testing module 2 is taken out, the corresponding testing items cannot be performed. To avoid such a situation, the present invention is designed as follows: an on-off driving member 9 is installed on the mounting plate 4, and the on-off driving member 9 can toggle the relative positions of the internal terminal 5 and the external terminal 6 on the mounting plate 4, so that the internal terminal 5 is separated from the terminal seat 7 under the toggle, and the external terminal 6 is moved away from the main control board 3 and moves toward the inside of the testing cabinet 1 under the toggle;

[0057] A signal light 10 is installed outside the main control board 3 at a position corresponding to each external terminal 6 , and the switch state of the signal light 10 can be adjusted according to the position of the corresponding external terminal 6 .

[0058] When a detection module 2 is taken out for maintenance, the on-off drive 9 can disconnect the connection between the internal terminal 5 and the detection module 2, and can also directly move the external terminal 6 to the inside of the detection cabinet 1, so that the external test cable cannot be plugged into the external terminal 6. Furthermore, the signal light 10 prompts the detection personnel that the detection module 2 is currently in "maintenance status" and the corresponding items cannot be tested.

[0059] In the present invention, a plurality of detection modules 2 are installed in partitions within the detection cabinet 1. When a certain detection module 2 needs to be inspected and repaired, the relative positions of the internal terminal head 5 and the external terminal head 6 are moved by the on-off driving member 9, so that the external terminal head 6 cannot be plugged in with an external test cable, and the internal terminal head 5 is disconnected from the detection module 2. This facilitates the disassembly, assembly and inspection of one of the detection modules 2, while the other detection modules 2 can perform inspection work normally. It also ensures that the inspection module 2 under inspection will not perform a wiring inspection process and obtain erroneous results, thereby improving the efficiency of the inspection and further ensuring the accuracy of the inspection.

[0060] The external terminal 6 can be placed outside the main control board 3, or can be moved into the detection cabinet 1, wherein the external terminal 6 is placed outside the main control board 3 for the external terminal 6 to be placed outside the main control board 3, such as Figure 4 As shown, a through slot 11 for the external terminal 6 to pass through is provided on the main control board 3 , and the width of the through slot 11 is greater than the width of the external terminal 6 , so that the external terminal 6 can pass through the through slot 11 or detach from the through slot 11 .

[0061] In the present invention, the on-off driving member 9 can toggle the relative positions of the inner terminal 5 and the outer terminal 6 on the mounting plate 4, so that the inner terminal 5 is separated from the terminal block 7 and the outer terminal 6 is moved away from the main control board 3 and moves toward the inside of the detection cabinet 1. Specifically, Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the on-off driving member 9 includes a movable seat 91 movably arranged on the mounting plate 4 and a connecting seat 92 mounted on the movable seat 91;

[0062] The external terminal block 6 is installed on the connecting seat 92, and a wiring tube 93 is installed on the connecting seat 92. The connecting cable is placed in the wiring tube 93, and the wiring tube 93 can fix the connecting cable. The internal terminal block 5 is installed at the end of the wiring tube 93, and the end of the wiring tube 93 is opposite to the terminal block 7.

[0063] Furthermore, in order to adjust the relative position of the external terminal 6, the present invention has the following design: a first arc-shaped slide groove 94 and a second arc-shaped slide groove 95 are provided on the mounting plate 4, and the circular positions of the first arc-shaped slide groove 94 and the second arc-shaped slide groove 95 are consistent, and a slide seat 96 is provided on one side of the movable seat 91 close to the mounting plate 4, and the slide seat 96 is slidably arranged in the first arc-shaped slide groove 94;

[0064] An arc-shaped rack 97 is installed in the second arc-shaped slide groove 95 , a first drive motor 98 is installed on the movable seat 91 , a drive shaft end of the first drive motor 98 is connected to a gear 99 , and the gear 99 meshes with the arc-shaped rack 97 .

[0065] The sliding seat 96 is fitted with the inner wall of the first arc-shaped sliding groove 94. The first arc-shaped sliding groove 94 is used to limit the overall motion trajectory of the movable seat 91. The centers of the first arc-shaped sliding groove 94 and the second arc-shaped sliding groove 95 are consistent. Therefore, the movement of the entire movable seat 91 can be regarded as a rotational motion along the arc trajectory.

[0066] Among them, the gear 99 only meshes with the arc-shaped rack 97 and does not interfere with the second arc-shaped slide groove 95. The first drive motor 98 drives the gear 99 to rotate. Under the rotation of the gear 99, the gear 99 can be driven to move along the direction of the arc-shaped rack 97, thereby driving the movable seat 91 to rotate as a whole. The rotational movement of the movable seat 91 can synchronously drive the internal terminal head 5, the external terminal head 6 and the connecting cable to move.

[0067] Assuming that in the initial state, the external terminal connector 6 is horizontally inserted into the through slot 11 , during the rotational movement, the external terminal connector 6 is driven away from the through slot 11 by the movable seat 91 and moves into the detection cabinet 1 .

[0068] Correspondingly, in the initial state, the wiring seat 7 is connected to the inner wiring head 5 , and the movable seat 91 drives the inner wiring head 5 to separate from the wiring seat 7 .

[0069] In the present invention, the switch state of the signal light 10 can be adjusted according to the position of the corresponding external terminal 6. When the external terminal 6 is in the groove 11, the signal light 10 is in an off state. When the external terminal 6 moves to the inside of the detection cabinet 1, the signal light 10 is on.

[0070] Specifically, Figure 7 and Figure 8 As shown, a wiring board 12 is installed on the side of the main control board 3 close to the inside of the detection cabinet 1, and a wiring slot 13 is provided outside the wiring board 12. A conductive sheet is built into the wiring slot 13, and the conductive sheet is connected to the signal lamp 10. A sliding seat 14 is installed on the mounting plate 4, and the sliding seat 14 is directly opposite to the wiring board 12;

[0071] The sliding seat 14 has a built-in power supply, and a conductive head 15 is disposed outside the sliding seat 14. The power supply is connected to the conductive head 15. The conductive head 15 faces the wiring slot 13 and can be plugged into the wiring slot 13.

[0072] When the conductive head 15 is inserted into the wiring slot 13 , the power supply is turned on to connect the signal light 10 .

[0073] In the initial state, the conductive head 15 is far away from the wiring slot 13. At this time, the power supply cannot supply power to the signal light 10, and the signal light 10 does not light up. When the conductive head 15 follows the sliding seat 14 and approaches the wiring board 12, and the conductive head 15 is inserted into the wiring slot 13, the power supply is connected to the signal light 10 and supplies power to the signal light 10. At this time, the signal light 10 lights up.

[0074] In the present invention, since the inner terminal 5 follows the movable seat 91 to perform a rotational motion, it is a curved motion, and the plugging process between the terminal seat 7 and the inner terminal 5 is usually a short linear motion, the curved motion may not be able to plug and disassemble the terminal seat 7 and the inner terminal 5. Therefore, the present invention makes the following design, such as Figure 7 , Fig. 9 and Fig.10 As shown, a first slide rail 16 and a second slide rail 17 are installed on the mounting plate 4, the wiring seat 7 is slidably disposed in the first slide rail 16, and the sliding seat 14 is slidably disposed in the second slide rail 17;

[0075] A connecting plate 18 is installed on the side of the mounting plate 4 away from the first slide rail 16, a first slide groove 19 is provided on the mounting plate 4 at a position facing the first slide rail 16 and the second slide rail 17, and a second slide groove 20 is provided on the connecting plate 18 at a position facing the first slide rail 16 and the second slide rail 17;

[0076] A first slider 21 is connected to the side of the wiring seat 7 close to the connecting plate 18, and a second slider 22 is connected to the side of the sliding seat 14 close to the connecting plate 18. The first slider 21 and the second slider 22 are both slidably disposed in the first slide groove 19 and the second slide groove 20;

[0077] A second drive motor 23 is installed on the connecting plate 18, and a threaded shaft 24 is connected to the driving shaft end of the second drive motor 23. A bearing seat 25 is installed on the connecting plate 18, and the end of the threaded shaft 24 is rotatably installed in the bearing seat 25. The first slider 21 and the second slider 22 are both threadedly matched with the threaded shaft 24.

[0078] Driven by the second driving motor 23, the threaded shaft 24 can be driven to rotate. The rotation of the threaded shaft 24 can drive the first slider 21 to move in the first slide groove 19 and the second slide groove 20, and can also drive the second slider 22 to move in the first slide groove 19 and the second slide groove 20. The first slider 21 can drive the terminal block 7 to move along a straight line, thereby driving the terminal block 7 to move toward the side away from the inner terminal head 5, thereby realizing the disassembly between the terminal block 7 and the inner terminal head 5. The second slider 22 can drive the sliding seat 14 to move along a straight line, thereby driving the conductive head 15 to be inserted into the terminal slot 13.

[0079] The directions of the first slide groove 19 and the second slide groove 20 are consistent with the direction of the inner terminal 5 .

[0080] In order to realize the synchronous change of the signal lamp 10 when the wiring base 7 and the inner wiring head 5 are disassembled, the present invention makes the following design, such as Fig.10 As shown, the threaded shaft 24 is composed of a first shaft section 241 and a second shaft section 242 connected together;

[0081] The threads on the first shaft section 241 and the second shaft section 242 are in opposite directions, the first slider 21 is threadedly matched with the first shaft section 241, and the second slider 22 is threadedly matched with the second shaft section 242;

[0082] The second driving motor 23 drives the first shaft section 241 and the second shaft section 242 to rotate synchronously, so as to drive the first slider 21 and the second slider 22 to move toward each other or move away from each other.

[0083] Assuming that in the initial state, the inner terminal head 5 is plugged into the terminal seat 7, and the conductive head 15 is away from the terminal slot 13, driven by the second drive motor 23, the first shaft segment 241 and the second shaft segment 242 rotate synchronously to drive the first slider 21 and the second slider 22 to move in opposite directions, and the first slider 21 drives the terminal seat 7 to move toward the side away from the inner terminal head 5 to achieve the disassembly between the terminal seat 7 and the inner terminal head 5, and the second slider 22 can drive the sliding seat 14 to move along a straight line, thereby driving the conductive head 15 to be plugged into the terminal slot 13, and the signal light 10 is powered on and lit.

[0084] During the above implementation process, when the connection between the terminal block 7 and the internal terminal head 5 is disconnected, the signal light 10 is turned on, and at the same time, the first drive motor 98 can be driven to make the external terminal head 6 move away from the groove 11 and enter the interior of the detection cabinet 1, thereby completing the entire disassembly process. This disassembly process is carried out when the corresponding detection module 2 is under maintenance, that is, when the corresponding detection module 2 is under maintenance, the second drive motor 23 is driven first to disassemble the terminal block 7 and the internal terminal head 5 and the signal light 10 is turned on, reminding the detection personnel that the detection module 2 cannot perform the detection work at this time. After that, the first drive motor 98 drives the external terminal head 6 away from the groove 11 and enters the interior of the detection cabinet 1, so that the external test cable cannot be inserted into the external terminal head 6, and the detection process cannot be carried out. This design can avoid the situation where the detection work implemented when the signal light 10 fails is incorrect.

[0085] In the present invention, each detection module 2 is installed as follows: Figure 1 and Figure 2 As shown, a support frame 26 is installed in the detection cabinet 1 , and a plurality of placement cavities 27 are formed in the support frame 26 , and each detection module 2 is correspondingly placed in the placement cavity 27 .

[0086] A plurality of sockets 28 are installed on the side wall of the support frame 26 close to the mounting plate 4 . The sockets 28 correspond to the detection modules 2 one by one. The ends of the wires 8 are connected to the sockets 28 , and the wires 8 and the sockets 28 are always connected.

[0087] Each detection module 2 includes a box body 29 and a detection circuit disposed in the box body 29 . A plug is installed on the outer wall of the box body 29 . The plug is electrically connected to the detection circuit and can be plugged into the socket 28 .

[0088] To facilitate the removal of the box body 29, Figure 2 As shown, the detection cabinet 1 is provided with a cabinet opening 30 , which is opposite to the interior of the placement cavity 27 , and a switch door 31 is installed at the cabinet opening 30 .

[0089] When it is necessary to overhaul a certain detection module 2, open the switch door 31 and directly take out the box body 29. During the removal process, the plug is detached from the socket 28. After the overhaul is completed, the box body 29 is inserted into the placement cavity 27 so that the plug is plugged into the socket 28 to achieve conduction between the plug and the socket 28. At the same time, the first drive motor 98 drives the external terminal 6 to reset, and the second drive motor 23 drives the terminal block 7 and the internal terminal 5 to restore the plug-in state, and the signal light 10 goes out. At this time, the detection circuit is connected to the corresponding detection ports on the medium and low voltage switch cabinets through the wire 8, the terminal block 7, the internal terminal 5, the connecting cable, the external terminal 6, and the test cable in sequence to realize the implementation of the corresponding detection items.
