[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

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

[0051] The detection module 2 generally includes a loop resistance detection module, a mechanical characteristic detection module, a grounding 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 mounted on the mounting plate 4 , one end of the wiring base 7 corresponds to the detection module 2 one by one and is connected via 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 number of detection modules 2 are installed in partitions within the detection cabinet 1. When it is necessary to repair a certain detection module 2, the relative positions of the internal connection terminal 5 and the external connection terminal 6 are toggled by the on-off driving member 9, so that the external connection terminal 6 cannot be plugged by an external test cable, and the connection between the internal connection terminal 5 and the detection module 2 is disconnected. This not only facilitates the disassembly and repair of one of the detection modules 2 while allowing other detection modules 2 to carry out detection work normally, but also ensures that the repaired detection module 2 will not undergo a wiring detection process to obtain incorrect results, improving the detection efficiency and further ensuring the detection accuracy.

[0060] The external connection terminal 6 can be placed outside the main control board 3 or toggled into the detection cabinet 1. Among them, when the external connection terminal 6 is placed outside the main control board 3, the external plug-in end of the external connection terminal 6 is placed outside the main control board 3. As Figure 4 shown, a through slot 11 for the external connection 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 connection terminal 6, so as to facilitate the external connection terminal 6 to penetrate or disengage from the through slot 11.

[0061] In the present invention, the on-off driving member 9 can toggle the relative positions of the internal connection terminal 5 and the external connection terminal 6 on the mounting plate 4, so that the internal connection terminal 5 disengages from the connection base 7 under toggling, and the external connection terminal 6 moves away from the main control board 3 and towards the interior of the detection cabinet 1 under toggling. Specifically, as Figure 5 、 Figure 6 、 Figure 7 and Figure 8 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 connection terminal 6 is mounted on the connecting seat 92. A wiring pipe 93 is mounted on the connecting seat 92, and the connecting cable is placed inside the wiring pipe 93. The wiring pipe 93 can fix the connecting cable, and the internal connection terminal 5 is mounted at the end of the wiring pipe 93, and the end of the wiring pipe 93 is directly opposite to the connection base 7.

[0063] Furthermore, in order to toggle the relative position of the external connection terminal 6, the present invention makes the following design. The mounting plate 4 is provided with a first arc-shaped chute 94 and a second arc-shaped chute 95, and the circular positions of the first arc-shaped chute 94 and the second arc-shaped chute 95 are the same. A sliding seat 96 is arranged on the side of the movable seat 91 close to the mounting plate 4, and the sliding seat 96 is slidably arranged in the first arc-shaped chute 94;

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

[0065] The sliding seat 96 fits the inner wall of the first arc-shaped chute 94. The first arc-shaped chute 94 is used to define the movement track of the whole movable seat 91. The centers of the first arc-shaped chute 94 and the second arc-shaped chute 95 coincide. Therefore, the movement of the whole movable seat 91 can be regarded as a rotational movement along an arc track.

[0066] Among them, the gear 99 only meshes with the arc-shaped rack 97 and does not interfere with the second arc-shaped chute 95. The first driving 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, so as to drive the whole movable seat 91 to perform a rotational movement. The rotational movement of the movable seat 91 can synchronously drive the inner connection head 5, the outer connection head 6 and the connecting cable to move.

[0067] Assume that in the initial state, the outer connection head 6 passes through the through slot 11 in a horizontal state. Under the rotational movement, the outer connection head 6 is driven by the movable seat 91 to move away from the through slot 11 and move into the detection cabinet 1.

[0068] Correspondingly, in the initial state, the connection base 7 is connected to the inner connection head 5, while the movable seat 91 drives the inner connection head 5 to disengage from the connection base 7.

[0069] In the present invention, the on-off state of the signal lamp 10 can be adjusted according to the position of the corresponding outer connection head 6. When the outer connection head 6 is in the through slot 11, the signal lamp 10 is in an off state. When the outer connection head 6 moves into the interior of the detection cabinet 1, the signal lamp 10 lights up.

[0070] Specifically, as Figure 7 and Figure 8 shown, a connection board 12 is installed on the side of the main control board 3 close to the interior of the detection cabinet 1. A connection slot 13 is provided outside the connection board 12. Conductive sheets are arranged in the connection slot 13. The conductive sheets are connected to the signal lamp 10. A sliding seat 14 is installed on the mounting plate 4. The sliding seat 14 faces the connection board 12.

[0071] A power supply is arranged inside the sliding seat 14. A conductive head 15 is arranged outside the sliding seat 14. The power supply is connected to the conductive head 15. The conductive head 15 faces the connection slot 13 and can be inserted into the connection slot 13.

[0072] Among them, when the conductive head 15 is inserted into the connection slot 13, the power supply is conductively connected to the signal lamp 10.

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

[0074] In the present invention, since the inner connection terminal 5 rotates following the movement of the movable seat 91, which belongs to a curvilinear motion, while the insertion process between the connection base 7 and the inner connection terminal 5 is usually a short linear motion, the curvilinear motion may not be able to perform the insertion and disassembly between the connection base 7 and the inner connection terminal 5. Therefore, the present invention makes the following design, as Figure 7 , Figure 9 and Figure 10 shown, a first slide rail 16 and a second slide rail 17 are installed on the mounting plate 4. The connection base 7 is slidably arranged in the first slide rail 16, and the sliding seat 14 is slidably arranged in the second slide rail 17;

[0075] A connecting plate 18 is installed on one side of the mounting plate 4 away from the first slide rail 16. A first chute 19 is arranged on the mounting plate 4 at positions corresponding to the first slide rail 16 and the second slide rail 17. Second chutes 20 are arranged on the connecting plate 18 at positions corresponding to the first slide rail 16 and the second slide rail 17;

[0076] One side of the connection base 7 close to the connecting plate 18 is connected with a first slider 21, and one side of the sliding seat 14 close to the connecting plate 18 is connected with a second slider 22. Both the first slider 21 and the second slider 22 are slidably arranged in the first chute 19 and the second chute 20;

[0077] A second driving motor 23 is installed on the connecting plate 18. The driving shaft end of the second driving motor 23 is connected with a threaded shaft 24. A bearing seat 25 is installed on the connecting plate 18. The end of the threaded shaft 24 is rotatably installed in the bearing seat 25. Both the first slider 21 and the second slider 22 are in threaded cooperation 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 chute 19 and the second chute 20, and can also drive the second slider 22 to move in the first chute 19 and the second chute 20. The first slider 21 can drive the connection base 7 to move along a straight line, so as to drive the connection base 7 to move away from the inner connection terminal 5, realizing the disassembly between the connection base 7 and the inner connection terminal 5. The second slider 22 can drive the sliding seat 14 to move along a straight line, so as to drive the conductive head 15 to be inserted into the connection slot 13.

[0079] Wherein, the directions of the first chute 19 and the second chute 20 are the same as the direction of the inner connection terminal 5.

[0080] To synchronously realize the change of the signal lamp 10 when disassembling between the connection base 7 and the inner connection terminal 5, the present invention makes the following design, as Figure 10 shown, the threaded shaft 24 is composed of a first shaft section 241 and a second shaft section 242 connected;

[0081] The thread directions on the first shaft section 241 and the second shaft section 242 are opposite. The first slider 21 is in threaded engagement with the first shaft section 241, and the second slider 22 is in threaded engagement with the second shaft section 242;

[0082] Among them, the second drive 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 towards each other or away from each other.

[0083] Assume that in the initial state, the inner terminal 5 is plugged into the terminal block 7, and the conductive head 15 is away from the wiring groove 13. Driven by the second drive motor 23, the first shaft section 241 and the second shaft section 242 rotate synchronously, so as to drive the first slider 21 and the second slider 22 to move away from each other. The first slider 21 drives the terminal block 7 to move towards the side away from the inner terminal 5, realizing the disassembly between the terminal block 7 and the inner terminal 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 plugged into the wiring groove 13, and the signal lamp 10 is turned on and lit.

[0084] In the above implementation process, when the disconnection between the terminal block 7 and the inner terminal 5 is completed, the signal lamp 10 is lit. At the same time, the first drive motor 98 can be driven to make the outer terminal 6 move away from the through groove 11 and enter the inside of the detection cabinet 1, which completes the entire disassembly process. This disassembly process is carried out when the corresponding detection module 2 is being repaired, that is: when the corresponding detection module 2 is being repaired, the second drive motor 23 is driven first, so that the disassembly between the terminal block 7 and the inner terminal 5 is carried out and the signal lamp 10 is lit, reminding the detection personnel that the detection module 2 cannot perform detection work at this time. Then the first drive motor 98 is driven to drive the outer terminal 6 to move away from the through groove 11 and enter the inside of the detection cabinet 1, so that the external test cable cannot be inserted into the outer terminal 6 and the detection process cannot be carried out. This design can avoid the situation where the detection work carried out when the signal lamp 10 fails is incorrect.

[0085] In the present invention, for installing each detection module 2, as Figure 1 and Figure 2 shown, a support frame 26 is installed in the detection cabinet 1. 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 end of the wire 8 is connected to the socket 28, and the wire 8 and the socket 28 always remain connected.

[0087] Each detection module 2 includes a box body 29 and a detection circuit placed 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 the plug can be plugged into the socket 28.

[0088] For the convenience of taking out the box body 29, as Figure 2 shown, outside the detection cabinet 1, there is a cabinet opening 30, and the cabinet opening 30 faces the inside of the placement cavity 27, and a switch door 31 is installed at the cabinet opening 30.

[0089] When it is necessary to repair a certain detection module 2, open the switch door 31 and directly take out the box body 29. During the taking-out process, the plug is separated from the socket 28. After the repair is completed, place the box body 29 into the placement cavity 27 so that the plug is inserted into the socket 28 to achieve the conduction between the plug and the socket 28. At the same time, the first driving motor 98 drives the external wiring head 6 to reset, and the second driving motor 23 drives the wiring seat 7 and the internal wiring head 5 to resume the inserted state, and the signal lamp 10 goes out. At this time, the detection circuit sequentially passes through the wire 8, the wiring seat 7, the internal wiring head 5, the connection cable, the external wiring head 6, and the test cable to connect to the corresponding detection ports on the medium and low voltage switchgear, so as to realize the corresponding detection items.

[0090] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
