Description

Technical Field

[0001] This application relates to the field of power distribution cabinets, and more particularly to a power distribution cabinet and a method for testing power distribution cabinets. Background Technology

[0002] A distribution cabinet is the final stage equipment in a power distribution system, and it is a general term for the motor control center. Distribution cabinets are used in situations where the load is relatively dispersed and there are few circuits.

[0003] A distribution cabinet consists of a cabinet body, which houses electrical distribution equipment, including switches, circuit breakers, fuses, buttons, indicator lights, meters, and wiring. These components are assembled to form a power distribution device that achieves its designed functions.

[0004] However, after the distribution cabinet is actually put into use, due to its complex internal structure, if there are errors in the connection of internal components during the production process, it is easy to damage the electrical equipment connected to the distribution cabinet or the distribution cabinet itself, resulting in economic losses or potential safety hazards. Therefore, improvements are needed. Summary of the Invention

[0005] In order to improve the problem that if the internal component connection error occurs in the production of the power distribution cabinet in the related technology, it may cause economic losses or hidden safety hazards in actual use, this application provides a power distribution cabinet and a power distribution cabinet testing method.

Output sockets are provided on the functional areas. A connection detection module, a test processing module, and an abnormality warning module are provided inside the cabinet.

[0008] The connection detection module is installed on the cabinet and is used to detect whether the output port is electrically connected to the external circuit and send a connection success signal or a connection failure signal.

[0009] The test processing module is installed on the cabinet and coupled to the connection detection module. It is used to process and feedback the test results of the power distribution cabinet. After receiving the connection success signal, the test processing module receives and processes external signals, and sends a test normal signal or a test abnormal signal based on the processing results.

[0010] The anomaly warning module is installed on the cabinet. The anomaly warning module is coupled to both the connection detection module and the test processing module. The anomaly warning module is used to issue an anomaly warning when a connection failure signal or a test anomaly signal is received.

[0017] Optionally, an adjustment hole is provided on the side wall of the steering plate, the adjustment hole is connected to the sliding groove, an adjustment screw is threaded into the adjustment hole, and one end of the adjustment screw inserted into the adjustment hole is rotatably connected to the side wall of the sliding block.

[0018] By adopting the above technical solution, the sliding block can be controlled to slide in the sliding groove by rotating the adjusting screw, so that the access end can be inserted into the output socket by the sliding block, thereby improving the safety of the power distribution cabinet.

[0019] Optionally, a connecting rod is provided at the top of the first guide plate, and an adjusting sleeve is provided at the end of the connecting rod away from the first guide plate. A displacement rod is threaded into the adjusting sleeve, and a connecting rod is rotatably connected to the bottom of the displacement rod. A connecting rod is provided at the end of the connecting rod away from the displacement rod, and the end of the connecting rod away from the displacement rod is connected to the locking piece.

[0020] By adopting the above technical solution, the vertical movement of the locking pieces can be controlled by rotating the shift rod. This allows the distance between the locking pieces to be changed by rotating the shift rod, and the access end can be inserted between the locking pieces when the distance between them increases, thus improving the convenience of operation for the operator.

[0042] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0043] This application discloses a power distribution cabinet and a testing method for the power distribution cabinet. (Refer to...) Figure 1 and Figure 2A power distribution cabinet includes a cabinet body 1, which is a rectangular hollow structure. The interior of the cabinet body 1 is used to house components such as switches, circuit breakers, fuses, buttons, indicator lights, meters, and wires, enabling the components to be combined to provide power distribution functionality. The cabinet body 1 has several functional areas, each with several output ports 11. The cabinet body 1 is equipped with a connection detection module 12, a test processing module 13, an anomaly warning module 14, and a wireless transmission module 15.

[0044] The connection detection module 12 is selected as a voltage sensor. The connection detection module 12 is installed in the cabinet 1 at the output socket 11. When the power distribution cabinet needs to be tested, that is, when the external device is plugged into the output socket 11 through the access terminal, the connection detection module 12 can detect the plug-in point. When the external device is successfully connected to the output socket 11, a connection success signal is output. If the external device fails to connect to the output socket 11, a connection failure signal is output.

[0045] The test processing module 13, which is selected as a CPU, is set on the cabinet 1. The test processing module 13 is coupled to the connection detection module 12. When a connection success signal is received, the test processing module 13 processes and feeds back the test results of the power distribution cabinet and external equipment. When the test result is normal, a test normal signal is sent, and when the test result is abnormal, a test abnormal signal is sent.

[0046] The wireless transmission module 15 is selected as Bluetooth and is coupled to the test processing module 13. When the power distribution cabinet is connected to an external device and is being tested, the wireless transmission module 15 is used to communicate wirelessly with the external device and determine whether the power supply of the power distribution cabinet is normal based on the power consumption of the external device. The external device feeds back the power consumption to the wireless transmission module 15, and the wireless transmission module 15 then sends the power distribution information of the external device to the test processing module 13.

[0047] The anomaly warning module 14 is selected as an audible and visual alarm. It is coupled to the test processing module 13 and the connection detection module 12. When the connection detection module 12 sends a connection failure signal, the anomaly warning module 14 illuminates an indicator light, flashing a red light to indicate connection failure and a continuous green light to indicate successful connection. When the test processing module 13 sends a test anomaly signal, it will trigger a synchronized audible and visual alarm.

[0048] Reference Figure 2A turning plate 2 is detachably connected to the side wall of cabinet 1 via bolts. The turning plate 2 is a rectangular plate structure and is perpendicular to the side wall where the output socket 11 is located on cabinet 1. A second guide plate 5 is rotatably connected to the top of the turning plate 2 via a connecting rod. A storage groove 52 is provided on the side wall of cabinet 1, and the second guide plate 5 is inserted into the storage groove 52. When the second guide plate 5 is inserted into the storage groove 52, its side wall is flush with the side wall of cabinet 1. A connecting socket 51 is provided through the second guide plate 5 along the wall thickness direction. When the second guide plate 5 rotates on the turning plate 2, it can rotate to a position flush with the side wall where the output socket 11 is located on cabinet 1. Therefore, when the access end of an external device is connected to cabinet 1, the access end of the external device can be passed through the connecting socket 51 and then inserted into the output socket 11, thereby making the cable distribution neater.

[0049] Reference Figure 2 and Figure 3 A fixing mechanism is provided at the end of the second guide plate 5 away from the turning plate 2. The fixing mechanism is used to fix the second guide plate 5 when it is flush with the side wall of the cabinet 1. The fixing mechanism includes a fixing rod 6 and a fixing magnet 61. The fixing rod 6 is hinged to the side wall of the second guide plate 5 away from the turning plate 2. The fixing magnet 61 is glued to the end of the fixing rod 6 away from the hinge. A connecting groove 63 is provided on the side wall of the cabinet 1 for the fixing rod 6 to be rotatably inserted. A connecting magnet 62 that is magnetically attracted to the fixing magnet 61 is glued to the connecting groove 63. When the fixing rod 6 is inserted into the connecting groove 63, the fixing magnet 61 and the connecting magnet 62 are attracted, thereby completing the fixing of the second guide plate 5. A stabilizing groove 7 is provided on the side wall of the second guide plate 5, and the fixing rod 6 can be rotatably inserted into the stabilizing groove 7. When the fixing rod 6 is inserted into the stabilizing groove 7, the side wall of the fixing rod 6 is flush with the side wall of the stabilizing groove 7, so as to store the fixing rod 6.

[0050] Reference Figure 4 and Figure 5 A sliding groove 21 is formed on the side wall of the steering plate 2 along the width direction of the steering plate 2. A sliding block 22 is slidably inserted into the sliding groove 21 and is slidably connected to the sliding groove 21. An adjustment hole 3 is formed on the side wall of the steering plate 2. The adjustment hole 3 is connected to the sliding groove 21. An adjustment screw 31 is threaded into the adjustment hole 3. One end of the adjustment screw 31 inserted into the adjustment hole 3 is rotatably connected to the side wall of the sliding block 22. Therefore, the sliding block 22 can be controlled to slide in the sliding groove 21 by rotating the adjustment screw 31.

[0051] Reference Figure 4 and Figure 5A first guide plate 23 is welded and fixed to the side wall of the sliding block 22. As the sliding block 22 slides, the distance between the first guide plate 23 and the side wall where the output socket 11 is located on the cabinet 1 changes. A locking groove 24 is provided on the side wall of the first guide plate 23 away from the sliding block 22 along the length direction of the first guide plate 23. The locking groove 24 is a trapezoidal groove. A displacement block 26 is slidably inserted into the locking groove 24. A locking piece 27 is welded and fixed to the side wall of the displacement block 26 away from the first guide plate 23. Several locking pieces 27 are connected by locking springs 28. A locking hole 29 is provided on the side wall of the locking piece 27. The locking hole 29 is opened in accordance with the position of the output socket 11 and the connecting socket 51. The access end of the external device is inserted into the locking hole 29. At this time, the locking spring 28 is in a stretched state. The locking spring 28 pulls a pair of locking pieces 27 toward the access end of the external device to achieve locking of the access end. A locking rod 25 is welded and fixed to the bottom of the side wall of the first guide plate 23 near the locking piece 27. The locking rod 25 is connected to the locking piece 27 through a locking spring 28. A connecting rod 44 is welded and fixed to the top of the uppermost locking piece 27. A connecting rod 43 is welded and fixed to the end of the connecting rod 44 away from the locking piece 27. The connecting rod 44 and the connecting rod 43 are set perpendicularly. A displacement rod 42 is rotatably connected to the end of the connecting rod 43 away from the connecting rod 44. A connecting rod 4 is welded and fixed to the top of the first guide plate 23. An adjusting sleeve 41 is welded and fixed to the connecting rod 4. The inner side wall of the adjusting sleeve 41 has a threaded structure. The displacement rod 42 is threaded into the adjusting sleeve 41 so that the movement of the locking piece 27 in the vertical direction can be controlled by rotating the displacement rod 42.

[0052] The implementation principle of the distribution cabinet and its testing method in this application is as follows: When the distribution cabinet in this application is in use, the operator can first connect the turn plate 2 to the cabinet body 1 with bolts, then rotate the second guide plate 5 so that the second guide plate 5 is flush with the side wall of the cabinet body 1, then rotate the fixing rod 6 out from the stabilizing groove 7 so that the fixing rod 6 is inserted into the connecting groove 63, then rotate the displacement rod 42 so that the displacement rod 42 drives the connecting rod 43 and the connecting rod 44 to move upward, thereby stretching the locking spring 28, and then the external device... The access end of the device passes through the connector 51 and is placed in the locking hole 29. Then, the shift rod 42 is rotated so that the locking piece 27 abuts against the access end. Then, the adjusting screw 31 is rotated so that the sliding block 22 moves in the sliding groove 21 toward the cabinet 1 and drives the access end to be inserted into the output connector 11. At this time, the connection detection module 12 detects the access end to check whether the connection is successful. If the connection is successful, the test processing module 13 tests the distribution cabinet and the test result is fed back through the abnormal warning module 14.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
