[0025] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] See Figures 1-4 , a large-current Hall workbench cabinet 100 provided by the present utility model. The large-current Hall workbench cabinet 100 includes a cabinet body 10, a Hall current power supply device 20 arranged at the top of the cabinet body 10, a plurality of Hall control boxes 30 arranged sequentially from top to bottom below the Hall current power supply device 20, and a plurality of Hall current test devices 40 arranged sequentially from top to bottom below the Hall control boxes 30 and having the same number as the Hall control boxes 30. A signal output interface is arranged on the Hall control box 30, and an external measurement device for measuring current is connected to the signal output interface. The Hall current power supply device 20 is connected to and supplies power to the Hall control box 30. In the embodiment provided by the present utility model, the current power supply device is a power strip for providing current and is externally connected to an external power supply to achieve power supply.

[0027] Such as Figure 1As shown, in this embodiment, by arranging a plurality of Hall control boxes 30 above the Hall current test device 40, the convenience of operation for the staff can be effectively improved. In addition, in another embodiment, the Hall control boxes 30 can be arranged below the plurality of Hall current test devices 40 in sequence from top to bottom. Inside the cabinet 10 of the large current Hall workbench cabinet 100 provided by the present utility model, a plurality of second mounting plates 13 for mounting the Hall control boxes 30 inside the cabinet 10 are further arranged, and the plurality of Hall control boxes 30 are arranged in sequence from top to bottom inside the cabinet 10 through the second mounting plates 13. By arranging the Hall control boxes 30 in sequence from top to bottom inside the cabinet 10 by using the second mounting plates 13, while meeting the requirement of measuring multiple groups of currents simultaneously, the installation space occupied by the Hall control boxes 30 can be effectively reduced.

[0028] As Figure 1 and Figure 2 shown, the Hall current test device 40 includes a copper bar 41, a Hall coil 43 sleeved on the copper bar 41, and connection copper bars 42 arranged at both ends of the copper bar 41 for connecting to the external device to be tested. The copper bar 41 passes through the Hall coil 43 and is connected to the connection copper bars 42. The device to be tested provides current to the copper bar 41 through the connection copper bars 42. The Hall control box 30 provides voltage and power supply to the Hall coil 43. After the Hall coil 43 senses the current on the copper bar 41 and outputs a corresponding proportional current to the Hall control box 30, the current flowing through the copper bar 41 is measured by an external measuring device. The working principle of the large current Hall workbench cabinet 100 provided by the present utility model is as follows: The Hall current power supply device 20 supplies power to the Hall control box 30. The Hall control box 30 outputs a stable voltage to supply power to the Hall coil 43. The device to be tested provides current to the copper bar 41 through the connection copper bars 42. When there is current flowing through the copper bar 41, the Hall coil 43 sensor senses the current and outputs a corresponding proportional current to the Hall control box 30 at the secondary side, and flows to the external measuring device through the signal output interface on the Hall control box 30 to measure the current magnitude. The external measuring device can directly measure the current flowing through the copper bar 41 by connecting an external Zhiyuan power analyzer; or an external current-to-voltage module is connected to the signal output interface to output a voltage signal to an oscilloscope, thereby measuring the current on the copper bar 41. In this embodiment, the current generated by the device to be tested flows through the Hall current test device 40 in a form of current flowing in and out one after another, thereby effectively saving the space occupancy rate of the Hall current test device 40.

[0029] As Figure 3As shown, in other embodiments, after the copper bar 41 is connected to the wiring copper busbar 42, the current generated by the device under test flows in and out of the wiring copper busbar 42 in the same direction. By passing the copper bar 41 through the Hall coil 43 and then connecting it to the wiring copper busbar 42, the current provided by the device under test can flow through the copper bar 41, through the Hall coil 43, and then induce a current, thereby further reducing the space occupied by the Hall current testing device 40 and avoiding the situation where the installation space increases due to a large copper busbar passing through the Hall coil 43.

[0030] As Figure 1 and Figure 4 As shown, in the cabinet body 10 of the large-current Hall workbench cabinet 100 provided by the present utility model, two Hall control boxes 30 are arranged. Corresponding to the lower part of the Hall control boxes 30, two Hall current testing devices 40 are arranged. Thus, while meeting the requirement of the large-current Hall workbench cabinet 100 for simultaneously measuring two groups of large currents, the space occupied by the Hall current testing devices 40 and the Hall control boxes 30 can be effectively reduced. In the embodiment provided by the present utility model, two first mounting plates 12 for mounting the Hall current testing devices 40 in the cabinet body 10 are further arranged in the cabinet body 10. The two Hall current testing devices 40 are arranged in sequence from top to bottom in the cabinet body 10 through the first mounting plates 12. By arranging the Hall current testing devices 40 in sequence from top to bottom in the cabinet through the two first mounting plates 12, the space occupied by the Hall current testing devices 40 in the cabinet body 10 can be further effectively reduced, improving the convenience for the staff during operation. In addition, in the embodiment provided by the present utility model, a plurality of merging holes 11 are arranged on the cabinet body 10. The cabinet body 10 is connected to the cabinet bodies 10 of the remaining large-current Hall workbench cabinets 100 through the merging holes 11, thereby further increasing the number of groups of large currents that can be simultaneously measured and meeting the requirement for simultaneously measuring four or more groups of large currents.

[0031] As Figure 1As shown, the Hall current testing device 40 further includes an insulating rod 44 disposed between the wiring copper bar 42 and the cabinet body 10, and the wiring copper bar 42 is fixedly connected to the cabinet body 10 through the insulating rod 44. Through the insulating rod 44, it can effectively prevent the current generated by the device under test from flowing through the copper bar 41, through the wiring copper bar 42, and then to the cabinet body 10, resulting in an electric shock when the operator contacts the cabinet body 10. Thus, it effectively improves the safety of the operator when using the large-current Hall workbench cabinet 100. In the embodiment provided by the present utility model, the Hall current testing device 40 further includes a copper bar support plate 45 disposed between the Hall coil 43 and the wiring copper bar 42, and the copper bar support plate 45 is an epoxy board. Through the copper bar support plate 45, it can effectively provide a supporting force for the copper bar 41, ensuring the stability of the copper bar 41 after passing through the Hall coil 43 and connecting to the inside of the Hall coil 43. Thus, it effectively improves the stability and accuracy of the Hall coil 43 in sensing the current on the copper bar 41, and avoids the failure of the Hall current testing device 40. In addition, by using an epoxy board to make the copper bar support plate 45, it can further play an insulating role, further preventing the current on the copper bar 41 from flowing to the cabinet body 10, thereby further improving the safety of the operator when using the large-current Hall workbench cabinet 100.

[0032] As Figure 2 and Figure 3 shown, the wiring copper bar 42 is further provided with a plurality of first mounting holes 421 for connecting to the device under test and second mounting holes 422 for connecting to the copper bar 41. By using locking parts such as bolts, studs, and pins to pass through the first mounting holes 421 on the wiring copper bar 42 and lock them inside the device under test, it can effectively ensure the stability of the device under test fixed on the wiring copper bar 42, thereby improving the stability of the device under test providing current to the copper bar 41 through the wiring copper bar 42. In addition, after passing the copper bar 41 through the Hall coil 43, by using locking parts such as bolts, studs, and pins to pass through the second mounting holes 422 on the wiring copper bar 42 and lock them inside the copper bar 41, it can effectively ensure the stability of the fixed connection between the copper bar 41 and the adapter copper bar, and further improve the stability of the device under test providing current to the copper bar 41 through the wiring copper bar 42. In the embodiment provided by the present utility model, the bottom of the cabinet body 10 is provided with universal wheels 14, so that the operator can move the large-current Hall workbench cabinet 100 to the test position according to actual needs, further improving the convenience of the operator when using the large-current Hall workbench cabinet 100.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
