Description

Technical Field

[0001] This invention belongs to the field of control cabinet testing technology, specifically relating to a testing device for a network control cabinet. Background Technology

[0002] Most of the wiring in the control cabinet is connected using busbars. Busbars refer to the copper or aluminum busbars that connect the main switch in the electrical cabinet to the switches in each branch circuit in the power supply system. They are insulated and mainly used as conductors. The insulation performance of the busbars is crucial. If the insulation performance of the busbars is not ideal, safety accidents can easily occur, posing a significant safety hazard. Therefore, insulation testing is required to ensure the stability of the busbars in subsequent operation.

[0003] Chinese patent CN118937937A discloses a testing device and method for intelligent switchgear circuits, including a test bench with two manually operated slides symmetrically mounted on its upper surface. Clamps are installed at the output ends of both slides, and busbar components are detachably installed between the two clamps. In the aforementioned application, the equipment only tests the external insulation performance of the busbar components. However, in actual use, busbar components are prone to reduced energizing efficiency due to environmental factors, making it impossible for the testing equipment to measure the lifespan of each busbar component, thus reducing the testing range of the equipment. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a testing device for network control cabinets, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides a testing device for a network control cabinet, including a testing cabinet, the top of which is provided with a protective shell, the two sides of which are provided with loading ports, the inner surface of which is provided with a positioning and fixing device, the inner side of which is provided with a busbar detection device, and the top of the inner side of which is provided with a vertical plate. The internal components of the busbar testing equipment are fixedly connected to multiple hydraulic blocks. An arc-shaped push block is movably connected to the top of each hydraulic block. The bottom of each hydraulic block is fixedly connected to one end of a hose. The other end of the hose is fixedly connected to the bottom of a two-point pipe. The inner side of the two-point pipe is fixedly connected to the rear side of a hydraulic block. The rear side of the hydraulic block is fixedly connected to a vertical plate via a fixing plate. A push block is movably connected to the front side of the hydraulic block. A power supply detection block is fixedly connected to the front side of the push block. A spring is fixedly connected between the push block and the hydraulic block. An arc-shaped detection port is opened on the inner side of the power supply detection block. A detection line is fixedly connected to the top front side of the power supply detection block. The tail of the detection line is fixedly connected to the testing host. The bottom of the testing host is fixedly connected to the top inner side of the testing cabinet. Multiple connecting cables are fixedly connected to the top rear side of the testing cabinet. When the device starts testing, the busbar is connected to the parallel network controller, and the power is turned on to simulate the operation of the control cabinet. At this time, the device is driven to start, causing the power detection block to circulate inward. This allows multiple ports of the parallel network controller to detect whether the power supply is normal, thus increasing the detection range of the device and making it more applicable.

[0006] Preferably, magnetic connecting blocks are fixedly connected to both sides of the inner side of the arc-shaped detection port, and a coil conductive interface is fixedly connected to the inner surface of the energized power detection block.

[0007] Preferably, a drive device is fixedly connected to the rear side of the busbar component detection device, a parallel network controller is fixedly connected to the front surface of the vertical plate, the top of the connecting cable is fixedly connected to the rear network terminal of the parallel network controller, an intermittent switch stability detection component is movably connected to the bottom left side of the parallel network controller, and a power supply temperature detection component is movably connected inside the power supply detection block.

[0008] Preferably, the diameter of the arc-shaped detection port is smaller than the diameter of the connecting cable, and a reciprocating detection elastic clamp device is movably connected to the outside of the driving device.

[0009] Preferably, the intermittent switch stability detection component includes a gear, a rotating shaft, a rack, a second spring, a third hydraulic block, a second fixing plate, a second hose, a third fixing plate, a fourth hydraulic block, a second pusher block, and a network controller switch. The top of the drive device is movably connected to the rotating shaft, and the top of the rotating shaft is fixedly connected to the gear. The top of the drive device is fixedly connected to the rear side of the third hydraulic block via the second fixing plate. The front side of the third hydraulic block is movably connected to the rack, and the second spring is fixedly connected between the rack and the third hydraulic block. The rack meshes with the gear. The rear side of the third hydraulic block is fixedly connected to one end of the second hose, and the other end of the second hose is fixedly connected to the bottom of the fourth hydraulic block. The bottom of the fourth hydraulic block is fixedly connected to the front side of the vertical plate via the third fixing plate. The top of the fourth hydraulic block is movably connected to the second pusher block, and the bottom left side of the parallel network controller is fixedly connected to the network controller switch. An intermittent switch stability detection component is installed. After the equipment completes continuous operation testing, the drive device is started to reverse, causing the gear to rotate counterclockwise, which in turn causes the pusher block to move up and down in a cycle. This causes the network controller switch to open and close in a cycle, thereby allowing the instantaneous energizing resistance of the parallel network controller to be detected, thus increasing the equipment's detection range and making the equipment testing more comprehensive.

[0010] Preferably, the gear has four teeth, and the inner side of the network controller switch is fixedly connected to the mainboard power supply inside the parallel network controller via a power wire.

[0011] Preferably, the center of the push block two is on the same vertical line as the center of the network controller switch, and the bottom of the gear is at a higher horizontal level than the top of the drive device.

[0012] Preferably, the power cable temperature detection component includes a movable groove, a hydraulic block five, a push block three, a spring three, a hose three, a hydraulic block six, a push block four, and a temperature measuring plate. The inner surface of the power detection block has a movable groove. A hydraulic block five is fixedly connected inside the movable groove. A push block three is movably connected to the front of the hydraulic block five. A spring three is fixedly connected between the push block three and the hydraulic block five. One end of the hose three is fixedly connected to the rear of the hydraulic block five, and the other end of the hose three is fixedly connected to the rear of the hydraulic block six. The bottom of the hydraulic block six is ​​fixedly connected to the top of the power detection block. A push block four is movably connected to the front of the hydraulic block six, and a temperature measuring plate is fixedly connected to the front of the push block four. By setting up the power cable temperature detection component, when the equipment is continuously operating and testing its power, a large amount of heat is generated due to the long-term high-voltage operation of the connected cable. At this time, the temperature measuring plate moves inward to the outside of the connected cable to monitor the temperature of the connected cable in real time, thereby ensuring the normal quality of the equipment under high load and long-term operation, and expanding the testing range of the equipment.

[0013] Preferably, the surface of the temperature measuring plate has an arc-shaped opening, the shape of which is consistent with the outer shape of the connecting cable.

[0014] Preferably, multiple temperature sensors are fixedly connected inside the temperature measuring plate.

[0015] The advantages of this application are: (1) When the device starts testing, the busbar is connected to the parallel network controller and the power is turned on to make the device simulate the operating state of the control cabinet. At this time, the device is driven to start, so that the power supply detection block is closed inward in a cycle, so that multiple ports of the parallel network controller can detect whether the power supply is normal, thereby increasing the detection range of the device and making the device more applicable.

[0016] (2) After the equipment completes continuous working test, the application starts the drive equipment to reverse, so that the gear rotates counterclockwise, so that the push block moves up and down in cycles, so that the network controller switch opens and closes in cycles, so that the instantaneous power resistance of the parallel network controller can be detected, thereby increasing the detection range of the equipment and making the equipment detection more comprehensive.

[0017] (3) When the equipment is tested for continuous power, a lot of heat will be generated due to the long-term high voltage power supply of the connecting cable. At this time, the temperature measuring plate moves inward to the outside of the connecting cable to monitor the temperature of the connecting cable in real time, thereby ensuring that the equipment is of normal quality under high load and long-term operation, and expanding the testing range of the equipment.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0021] Example 1, as Figures 1-4 As shown, a testing device for a network control cabinet includes: The test cabinet 100 has a protective shell 200 on its top, and loading ports 300 on both sides of the protective shell 200 to allow the equipment to quickly load and unload busbar components. The inner surface of the test cabinet 100 is equipped with a positioning and fixing device 400 to fix busbar components of different sizes. Inside the positioning and fixing device 400, there is a busbar component testing device 500 to test the surface insulation of the busbar components. The top inner side of the test cabinet 100 is equipped with a vertical plate 700. The internal components of the busbar component testing equipment 500 are fixedly connected to multiple hydraulic blocks 902. An arc-shaped pusher 901 is movably connected to the top of each hydraulic block 902. The bottom of each hydraulic block 902 is fixedly connected to one end of a hose 903, and the other end of the hose 903 is fixedly connected to the bottom of a two-point pipe 904. The inner side of the two-point pipe 904 is fixedly connected to the rear side of a hydraulic block 906. The hose 903 and the two-point pipe 904 are configured to allow communication between the interior of each hydraulic block 902 and the interior of each hydraulic block 906. The rear side of each hydraulic block 906 is fixedly connected to a vertical plate 700 via a fixing plate 905. A pusher 907 is movably connected to the front side of each hydraulic block 906. A power detection block 909 is fixedly connected to the front side. A spring 908 is fixedly connected between the push block 907 and the hydraulic block 906. The spring 908 is set so that the push block 907 can automatically reset. An arc-shaped detection port 910 is opened on the inner side of the power detection block 909. A detection line 911 is fixedly connected to the top front side of the power detection block 909. The tail of the detection line 911 is fixedly connected to the detection host 912. The bottom of the detection host 912 is fixedly connected to the top inner side of the test cabinet 100. Multiple connecting cables 913 are fixedly connected to the top rear side of the test cabinet 100. The connecting cables 913 are set so that the parallel network controller 800 can operate at full load.

[0022] Magnetic connecting blocks are fixedly connected to both sides of the inside of the arc-shaped detection port 910, and a coil conductive interface is fixedly connected to the inner surface of the energized power detection block 909.

[0023] A drive device 600 is fixedly connected to the rear side of the busbar component testing device 500. A parallel network controller 800 is fixedly connected to the front surface of the vertical plate 700. The top of the connecting cable 913 is fixedly connected to the rear network terminal of the parallel network controller 800. An intermittent switch stability detection component 1000 is movably connected to the bottom left side of the parallel network controller 800. A power supply detection block 909 is movably connected to the inside of the power supply cable temperature detection component 1100.

[0024] The diameter of the arc-shaped detection port 910 is smaller than the diameter of the connecting cable 913, and a reciprocating detection elastic clip device is movably connected to the outside of the drive device 600.

[0025] When the device starts testing, the busbar is connected to the parallel network controller 800, and the power is turned on to simulate the operation of the control cabinet. At this time, the drive device 600 is started, causing the power detection block 909 to close in a loop. This allows multiple ports of the parallel network controller 800 to detect whether the power supply is normal, thus increasing the detection range of the device and making it more widely applicable.

[0026] In practical use, when the above-mentioned equipment starts testing, the busbar component is placed into the positioning and fixing device 400 through the loading port 300. The parallel network controller 800 is fixed on the upper side of the vertical plate 700. The parallel network controller 800 is connected to the busbar component, and the connecting cable 913 is connected to multiple connectors of the parallel network controller 800. After power is applied, the drive device 600 drives the busbar component testing device 500 to perform cyclic testing on the busbar component. At this time, the busbar component testing device 500 moves, causing the arc-shaped pusher 901 to move towards... The downward movement increases the internal pressure of hydraulic block 902, which is then transmitted to hydraulic block 906 via hose 903 and two-way pipe 904. This increases the internal pressure of hydraulic block 906, causing push block 907 to push outward and the power detection block 909 to move inward. This allows the arc-shaped detection port 910 to surround the outside of the connecting cable 913, enabling multiple ports of the parallel network controller 800 to detect whether the power is normal, thus expanding the detection range and making the equipment more applicable.

[0027] Example 2, as Figures 1-6 As shown, a testing device for a network control cabinet, based on Embodiment 1, includes an intermittent switch stability testing component 1000 comprising a gear 1001, a rotating shaft 1002, a rack 1003, a second spring 1004, a third hydraulic block 1005, a second fixing plate 1006, a second hose 1007, a third fixing plate 1008, a fourth hydraulic block 1009, a second push block 1010, and a network controller switch 1011. The top of the drive device 600 is movably connected to the rotating shaft 1002, and the top of the rotating shaft 1002 is fixedly connected to the gear 1001. The top of the drive device 600 is fixedly connected to the rear side of the third hydraulic block 1005 via the second fixing plate 1006. The front side of the third hydraulic block 1005 is movably connected to the rack 1003. A spring 1004 is fixedly connected between hydraulic block 3 and hydraulic block 1005. The spring 1004 is set so that rack 1003 can automatically reset. Rack 1003 meshes with gear 1001. The rear side of hydraulic block 3 is fixedly connected to one end of hose 2 1007. The other end of hose 2 1007 is fixedly connected to the bottom of hydraulic block 4 1009. The hose 2 1007 is set so that the inside of hydraulic block 3 1005 communicates with the inside of hydraulic block 4 1009. The bottom of hydraulic block 4 1009 is fixedly connected to the front side of vertical plate 700 through fixing plate 3 1008. Push block 2 1010 is movably connected to the top of hydraulic block 4 1009. Network controller switch 1011 is fixedly connected to the bottom left side of parallel network controller 800.

[0028] The gear 1001 has four teeth, and the inside of the network controller switch 1011 is fixedly connected to the main board power supply inside the parallel network controller 800 via a power wire.

[0029] The center of push block 2 1010 and the center of network controller switch 1011 are on the same vertical line, and the bottom horizontal height of gear 1001 is higher than the top horizontal height of drive device 600.

[0030] The intermittent switch stability detection component 1000 is set up. After the equipment completes continuous operation detection, the drive device 600 is started to reverse, causing the gear 1001 to rotate counterclockwise, causing the push block 1010 to move up and down cyclically, and causing the network controller switch 1011 to open and close cyclically. This allows the instantaneous energizing resistance of the parallel network controller 800 to be detected, thereby increasing the equipment detection range and making the equipment detection more comprehensive.

[0031] In practical use, when the above-mentioned equipment needs to perform instantaneous energization reactance testing on the parallel network controller 800, the drive device 600 is started to reverse, causing the rotating shaft 1002 to rotate, the gear 1001 to rotate counterclockwise, the rack 1003 to move to the right, and the internal pressure of the hydraulic block 1005 to increase. The internal pressure of the hydraulic block 1005 is transmitted to the hydraulic block 1009 through the hose 1007, increasing the internal pressure of the hydraulic block 1009. This causes the push block 1010 to move upward, opening the network controller switch 1011. When the gear 1001 rotates until its teeth separate from the rack 1003, the spring 1004 releases its elastic potential energy, causing the rack 1003 to automatically reset and the push block 1010 to move downward. This achieves the cyclic opening and closing of the network controller switch 1011, allowing the instantaneous energization reactance of the parallel network controller 800 to be detected, thereby increasing the equipment's detection range and making the detection more comprehensive.

[0032] Example 3, as Figures 1-8As shown, a testing device for a network control cabinet, based on Embodiment 1 and Embodiment 2, includes a power cable temperature detection component 1100 comprising a movable groove 1101, a hydraulic block 5 1102, a push block 3 1103, a spring 3 1104, a hose 3 1105, a hydraulic block 6 1106, a push block 4 1107, and a temperature measuring plate 1108. The inner surface of the power detection block 909 has a movable groove 1101. A hydraulic block 5 1102 is fixedly connected inside the movable groove 1101. A push block 3 1103 is movably connected to the front side of the hydraulic block 5 1102. The push block 3 1103 and the hydraulic block 5 1102... A spring 1104 is fixedly connected between the two parts. The spring 1104 is set to make the push block 1103 automatically reset. The rear side of the hydraulic block 1102 is fixedly connected to one end of the hose 1105. The other end of the hose 1105 is fixedly connected to the rear side of the hydraulic block 1106. The hose 1105 is set to make the interior of the hydraulic block 1102 communicate with the interior of the hydraulic block 1106. The bottom of the hydraulic block 1106 is fixedly connected to the top of the energized power detection block 909. The front side of the hydraulic block 1106 is movably connected to the push block 1107. The front side of the push block 1107 is fixedly connected to the temperature measuring plate 1108.

[0033] The surface of the temperature measuring plate 1108 has an arc-shaped opening, the shape of which is consistent with the outer shape of the connecting cable 913.

[0034] Multiple temperature sensors are fixedly connected inside the temperature measuring plate 1108.

[0035] The power cable temperature detection component 1100 is set up so that when the equipment is continuously working and the power is tested, a lot of heat will be generated due to the long-term high voltage power supply of the connecting cable 913. At this time, the temperature measuring plate 1108 moves inward to the outside of the connecting cable 913 to monitor the temperature of the connecting cable 913 in real time, thereby ensuring that the equipment is of normal quality under high load and long-term operation and expanding the testing range of the equipment.

[0036] When the above-mentioned equipment is used for continuous power testing, the connecting cable 913 generates a lot of heat due to prolonged high-voltage energization. The power detection block 909 closes inward, causing push block 3 1103 to move inward, increasing the internal pressure of hydraulic block 5 1102. This internal pressure is then transmitted to hydraulic block 6 1106 through hose 3 1105, increasing the internal pressure of hydraulic block 6 1106. This causes push block 4 1107 to push outward, allowing the temperature measuring plate 1108 to adhere to the outer surface of the connecting cable 913. This allows for real-time monitoring of the temperature of the connecting cable 913, ensuring normal equipment quality under high load and long-term operation, and expanding the equipment's testing range.
