Description

[0002] In the power system, the transformer is an indispensable core equipment. The stability and safety of its performance are directly related to the normal operation of the entire power system. Therefore, regular inspection and testing of transformers is essential. However, the traditional transformer inspection process often relies on manual operation, especially when carrying and picking up the transformer to be inspected, there are many inconveniences and potential safety hazards.

[0003] Although the existing transformer test bench integrates multiple test functions and can comprehensively evaluate the performance status of the transformer, the transportation and placement of the transformer still requires manual work. Specifically, the operator usually needs to manually carry the transformer to be tested to the test bench, which involves lifting, moving and placing the transformer. These operations not only require the operator to have high physical strength and skills, resulting in increased labor intensity for the operator, but also reduce the detection efficiency.

[0004] Moreover, accidents such as loss of control and slipping are prone to occur during operation. During transportation, the transformer may be subjected to external forces such as impact and vibration, which may cause its internal structure to loosen and components to be damaged, affecting the performance and life of the transformer, and even causing safety accidents, while threatening the safety of operators.

[0005] In view of the above problems, a transformer detection workbench is now designed. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0025] The embodiment of the present application provides a transformer testing workbench, which can solve the problem in the related art that although the transformer testing bench integrates multiple testing functions and can comprehensively evaluate the performance status of the transformer, the transportation and placement of the transformer still require manual work.

[0026] See also Figure 1-Figure 3A transformer detection workbench includes: a workbench 1, a traction mechanism 2, a lifting mechanism 3, a pneumatic clamp 4 and a feeding mechanism 5. The workbench 1 is provided with a detection station for transformer detection. The traction mechanism 2 is arranged on the workbench 1, and the traction mechanism 2 is connected to the lifting mechanism 3. The traction mechanism 2 is used to drive the lifting mechanism 3 to move along the length of the workbench 1. The lifting mechanism 3 is connected to the pneumatic clamp 4, and the pneumatic clamp 4 is used to grab the transformer module; the feeding mechanism 5 includes a linear slide rail 51 and a discharge plate 52. The linear slide rail 51 is arranged at one end of the workbench 1. The linear slide rail 51 is connected to the discharge plate 52 to drive the discharge plate 52 to rise and fall, and the discharge plate 52 is used to support the transformer module.

[0027] It should be noted that the detection station in this implementation scheme is provided with detection equipment for transformer detection which is not shown in the figure. The detection equipment includes a current transformer calibrator: used to test the interpolation characteristics of the current transformer to ensure that the output of the current transformer being tested accurately matches the corresponding input signal; an electrical safety detector: used to detect electrical safety indicators such as leakage and insulation impedance in the transformer, as well as the size of the ground resistance; a partial discharge detector: partial discharge refers to flashover discharge in a local area of ​​the power equipment, which may cause damage to the equipment and malfunction; a ratio tester: used to test the transformation ratio of the transformer, and to determine whether the transformation ratio is normal by comparing the ratio between the output voltage and the input voltage. The above equipment can be adjusted according to actual detection needs. The above detection equipment is all prior art and will not be described here.

[0028] In actual operation, when receiving the loading instruction, the linear slide 51 starts to work, driving the discharge plate 52 to descend to the ground, so that the staff can transport the transformer module and push it onto the discharge plate 52. Then, the linear slide 51 works again, driving the discharge plate 52 to rise, so that it can be grabbed by the pneumatic gripper 4. Then, after receiving the grabbing instruction, the pneumatic gripper 4 quickly grabs the transformer module to ensure that it is stable and does not fall off. After the transformer module is successfully grabbed, the lifting mechanism 3 starts to perform vertical movement to raise the pneumatic gripper 4 and the transformer module to avoid being blocked by obstacles. Then, the traction mechanism 2 starts to work and drives the lifting mechanism 3 to move along the length direction of the workbench 1. In this process, the pneumatic gripper 4 firmly clamps the transformer module to ensure that it does not shake or fall off during movement;

[0029] When the pneumatic clamp 4 carries the transformer module to the top of the inspection station, the traction mechanism 2 stops working, and the lifting mechanism 3 performs vertical movement again to control the transformer module to descend and fall into the inspection station. Subsequently, various inspection equipment on the inspection station starts working to inspect various performance parameters of the transformer.

[0030] Reset and next round of detection:

[0031] After a round of testing is completed, the pneumatic gripper 4 grabs the tested transformer module again, and the traction mechanism 2 and the lifting mechanism 3 work together to transport the transformer module back to the loading mechanism 5; the unloading plate 52 is driven by the linear slide rail 51 to rise to the initial position to prepare for the next round of loading operation. At the same time, the system can automatically replace the new transformer module to be tested and repeat the above steps to achieve continuous and automated testing.

[0032] Through the above operations, the transformer module can be automatically transported, the automatic loading function is realized, the labor intensity of manual operation is reduced, the detection efficiency and accuracy are effectively improved, and accidents such as operator loss of control and slipping during operation are avoided. The transformer is prevented from being subjected to external forces such as impact and vibration, which may cause the internal structure to loosen and components to be damaged, thereby reducing manual intervention and reducing operational risks.

[0033] As a preferred embodiment, Figure 1 and Figure 2 As shown, the present embodiment also includes a preset station 6, which is arranged on the workbench 1, and the preset station 6 is located between the pneumatic clamp 4 and the loading mechanism 5; the preset station 6 includes a rotating platform 61 and a group of discharge seats 62, the rotating platform 61 is arranged on the workbench 1, a group of the discharge seats 62 are relatively arranged on the rotating platform 61 and are used to receive the transformer module, and the rotating platform 61 is used to drive the discharge seat 62 to rotate.

[0034] In order to further improve the automation and efficiency of the detection process, the preset station 6 is located between the pneumatic clamp 4 and the feeding mechanism 5, and its main function is to provide an intermediate temporary storage and pre-processing area to prepare for the subsequent positioning and detection of the transformer module.

[0035] In actual operation, when the discharge plate 52 of the loading mechanism 5 descends to a suitable position, the staff pushes the transformer module on the conveying equipment to the discharge plate 52 and then opens the linear slide rail 51 again to lift the discharge plate 52 to the same height as the discharge seat 62 and then pushes it to the discharge plate 52.

[0036] Temporary storage and preprocessing of transformer module:

[0037] When it is necessary to inspect the next transformer module, the rotating platform 61 is turned on, and the rotating platform 61 drives the discharge seat 62 to rotate to the bottom of the pneumatic clamp 4. After preprocessing at the preset station 6, the pneumatic clamp 4 grabs the transformer module again and transports it to the top of the inspection station. At this time, the loading mechanism 5 works again to push the next transformer module to the top of the discharge plate 52 on the other side, ensuring the continuity of transformer inspection and further improving the degree of automation and inspection efficiency.

[0038] like Figure 5 As shown, in this embodiment, the rotating platform 61 includes a mounting frame 611, a driving motor 612 and a material tray 613, the mounting frame 611 is arranged at the bottom of the workbench 1, the driving motor 612 is arranged on the mounting frame 611, the material tray 613 is rotatably arranged on the workbench 1, and the output shaft of the driving motor 612 is connected to the material tray 613.

[0039] The driving motor 612 is mounted on the mounting frame 611 , and the material tray 613 is rotatably mounted on the workbench 1 . The material tray 613 is generally designed to be in the shape of a circular disc, and a suitable material placement seat 62 is disposed on its surface to support the transformer module.

[0040] In actual operation, the driving motor 612 is turned on, and the output shaft of the driving motor 612 drives the material tray 613 to rotate, thereby exchanging the positions of the two material discharging seats 62.

[0041] It should be noted that a reducer is provided on the mounting frame 611 in the present embodiment, the output shaft of the driving motor 612 is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to the material tray 613. When the driving motor 612 is started, the rotational power generated by it is first transmitted to the reducer, and the reducer converts the high-speed rotation of the motor into the low-speed rotation required by the material tray 613 through internal gears, bearings and other components. In this process, the reducer reduces the rotation speed and increases the torque, so that the material tray 613 can rotate smoothly and accurately, and carry the transformer module for positioning.

[0042] It should be noted that the linear slide in this embodiment, also known as the linear slide, is a guide rail system that achieves linear motion by sliding. It is mainly composed of two parts: a track and a slider. The track is used to provide a path for the slider to move, and the slider is installed on the track to achieve linear reciprocating motion by sliding.

[0043] A pneumatic gripper is a mechanical device controlled by air pressure. It drives the opening and closing of the gripper through air pressure to achieve the grasping and releasing of objects. This device is widely used in the field of industrial automation, especially in scenarios that require fast, accurate and controllable gripping actions. The above are all existing technologies and will not be repeated here.

[0044] Further, such as Figure 1 and Figure 2 As shown, the traction mechanism 2 in the present scheme includes a bracket 21, an electric push rod 22, a group of slide rods 23 and a group of sliders 24, the bracket 21 is arranged on the workbench 1, the electric push rod 22 is arranged on the bracket 21, the output shaft of the electric push rod 22 is connected to the lifting mechanism 3, a group of slide rods 23 are relatively arranged on the bracket 21, the slider 24 is slidably arranged on the outside of the slide rod 23, and one side of the slider 24 is connected to the lifting mechanism 3.

[0045] The traction mechanism 2 is an important component of the transformer inspection workbench, and is mainly used to drive and lift subsequent inspection mechanisms or components to ensure that the entire inspection process can proceed smoothly. Its working principle mainly relies on the synergy between the bracket 21, the electric push rod 22, the slide bar 23 and the slide block 24.

[0046] The electric push rod 22 is installed on the bracket 21. By controlling the extension and retraction of the electric push rod 22, a linear motion power can be generated to provide power for the lifting mechanism 3. When the electric push rod 22 is turned on, the piston rod of the electric push rod 22 drives the lifting mechanism 3 to move along the length of the workbench 1.

[0047] At the same time, the slide rods 23 are arranged on the bracket 21, which provide sliding tracks for the slider 24 to ensure that the slider 24 can move along a fixed direction. When the output shaft of the electric push rod 22 is extended or retracted, the power is transmitted to the slider 24 through the connecting piece, so that the slider 24 moves along the length of the slide rod 23, thereby supporting the lifting mechanism 3, the pneumatic clamp 4 and the transformer module, and limiting the moving trajectory of the lifting mechanism 3.

[0048] Specifically, Figure 1 and Figure 2 As shown, the lifting mechanism 3 in this embodiment is a cylinder or an electric push rod 2.

[0049] It can be understood that in this embodiment, the height of the pneumatic clamp can be adjusted by using a cylinder or an electric push rod.

[0050] In another example, Figure 4 As shown, in this embodiment, two groups of grooves are provided on the top of the discharge plate 52, and guide rods 7 are rotatably provided inside the grooves.

[0051] In actual operation, when the staff pushes the transformer module on the discharge plate 52 to the top of the discharge plate 52, the friction between the transformer module and the discharge plate 52 can be reduced by rotating the guide rod 7, thereby reducing the workload of the operator during the pushing process and facilitating the operation of the staff.
