Technical Field

[0001] This utility model relates to the field of sensor detection technology, and in particular to an integrated device for high current generator and sensor detection. Background Technology

[0002] Current detection is an important means of monitoring the operating status of power equipment. At present, with the continuous maturation of fluxgate current sensor technology, fluxgate current sensors have been increasingly widely used in power conversion and transmission systems such as new energy, energy storage, and power grids due to their inherent advantages such as high precision, low temperature drift, and low zero drift.

[0003] In existing technologies, traditional high-current generators and sensor detection systems operate independently, requiring manual installation and fixing of sensors, loading of measuring busbars, configuration of test parameters, and switching of test modes. A single detection process can take up to 30 minutes, which is difficult to meet the needs of large-scale production. Therefore, there is a need for an integrated high-current generator and sensor detection device to meet people's needs. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-5 An integrated device for high-current generator and sensor detection includes an electrical cabinet 100 and a high-current generator 101. A test bracket 102 is arranged on the side of the electrical cabinet 100. A test platform 103 is fixedly mounted on the test bracket 102. A positive terminal connection assembly 104 and a negative terminal connection assembly 105 are fixedly mounted on the test platform 103. A busbar 106 is arranged between the positive terminal connection assembly 104 and the negative terminal connection assembly 105. Both the positive terminal connection assembly 104 and the negative terminal connection assembly 105 are electrically connected to the high-current generator 101. The positive terminal connection assembly 104 includes a connector... The wiring frame 200 has a fixing block 201 and a connector 202 fixedly installed on it. The connector 202 is adapted to the busbar 106. By using the movable busbar 106 to pass through the current sensor 301, multiple sets of current sensors 301 can be tested at one time. At the same time, the positive terminal assembly 104 and the negative terminal assembly 105 are used to realize the automatic connection and power supply to the busbar 106. This not only improves the detection efficiency of the device for the current sensor 301, but also reduces the probability of danger caused by manual contact with high-voltage equipment, thus improving the safety of the equipment.

[0022] In an optional embodiment: a telescopic cylinder 203 is fixedly installed on the terminal block 200, and a terminal block 202 is fixedly installed on the output end of the telescopic cylinder 203.

[0023] It should be noted that the output terminal drive connector 202 of the telescopic cylinder 203 is connected to the terminal of the busbar 106 to supply power to the busbar 106.

[0024] In an optional embodiment: an L-shaped mounting bracket 300 is fixedly installed on the test bracket 102, a current sensor 301 is installed on the L-shaped mounting bracket 300 by bolts, and a busbar positioning support bracket 302 is fixedly installed on the L-shaped mounting bracket 300. Both the current sensor 301 and the busbar positioning support bracket 302 are adapted to the busbar 106.

[0025] It should be noted that the current sensors 301 to be tested are arranged on the L-shaped mounting bracket 300 and installed with bolts. There are gaps between the multiple sets of current sensors 301 to avoid mutual interference. At the same time, busbar positioning support brackets 302 are arranged between the L-shaped mounting brackets 300 to support the busbar 106, thereby ensuring that the busbar 106 can stably pass through the multiple sets of current sensors 301.

[0026] In an optional embodiment: an insulating extension rod 400 is fixedly installed at one end of the busbar 106, a slider 401 is fixedly installed on the insulating extension rod 400, a slide rail frame 402 is arranged on the side of the test bracket 102, and the slider 401 is slidably installed in the slide rail frame 402.

[0027] It should be noted that the movement of the insulating extension rod 400 is restricted by the slider 401 and the slide rail 402, and can only move within a fixed range, thereby ensuring the stability of the busbar 106 when it moves.

[0028] In an optional embodiment: a limiting groove 403 is provided on the inner wall of the slide rail frame 402, and a limiting slider 404 is slidably installed in the limiting groove 403, and the limiting slider 404 is fixedly installed on the slider 401.

[0029] In an optional embodiment: a U-shaped mounting bracket 405 is fixedly installed on the test platform 103, and two drive rollers 406 are rotatably mounted on the U-shaped mounting bracket 405, both of which are in contact with the insulating extension rod 400.

[0030] In an optional embodiment: two transmission wheels 407 are rotatably mounted on the U-shaped mounting bracket 405, and the same transmission belt 408 is movably sleeved on the two transmission wheels 407. A motor mounting bracket 409 is fixedly mounted on the U-shaped mounting bracket 405, and a drive motor 410 is fixedly mounted on the motor mounting bracket 409. The output end of the drive motor 410 is connected to the transmission wheels 407, and the transmission wheels 407 are connected to the drive roller 406.

[0031] It should be noted that the output of the drive motor 410 drives one transmission wheel 407 to rotate, and at the same time, the transmission wheel 407 drives another transmission wheel 407 to rotate through the transmission belt 408. The two rotating transmission wheels 407 drive the insulating extension rod 400 to move to a different position through the drive roller 406.

[0032] Working principle of this utility model:

[0033] When using this device, the current sensors 301 to be detected need to be arranged on the L-shaped mounting bracket 300 and installed using bolts. Multiple sets of current sensors 301 are spaced apart to avoid mutual interference. Simultaneously, busbar positioning support brackets 302 are arranged between the L-shaped mounting brackets 300 to support the busbar 106, ensuring that the busbar 106 can stably pass through the multiple sets of current sensors 301. The movement of the busbar 106 requires the activation of the drive motor 410. The output of the drive motor 410 drives a transmission wheel 407 to rotate. 407 drives another drive wheel 407 to rotate via a drive belt 408. The two rotating drive wheels 407 drive the insulating extension rod 400 to move to a certain position via a drive roller 406. The movement of the insulating extension rod 400 is restricted by the slider 401 and the slide rail frame 402, and can only move within a fixed range, thereby ensuring the stability of the busbar 106 when it moves. After the busbar 106 moves to a suitable position, the telescopic cylinder 203 is activated. The output end of the telescopic cylinder 203 drives the terminal 202 to connect with the terminal of the busbar 106, thereby powering the busbar 106.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
