Description

Technical Field

[0001] This utility model relates to the field of high-voltage power testing technology, specifically a high-voltage power testing cabinet. Background Technology

[0002] High-voltage testing equipment is a general term for equipment used to generate high voltage and impulse current for testing and researching various discharge phenomena, insulation performance, or current carrying capacity. The main equipment includes: power frequency test transformers, cascade power frequency test transformers, power frequency resonant test transformers, cascade resonant test equipment, DC high-voltage generators, cascade DC high-voltage generators, high-voltage rectifiers, impulse voltage generators, and impulse current generators. The development of power transmission and transformation projects and the electrical engineering manufacturing industry has placed new demands on high-voltage testing equipment. High-voltage testing laboratories generally require the ability to perform withstand voltage tests under different voltage waveforms, thus requiring a large initial investment in testing equipment. Many high-voltage laboratories in China generally face the problem of low utilization rate and poor efficiency of testing equipment. There is a desire to develop multi-functional testing equipment to improve equipment utilization and fully realize the benefits of testing equipment. High-voltage power line testing mainly involves inspecting the quality and insulation condition of the wires. Because power lines are used to transmit high-power electrical energy and operate under high voltage and high current conditions, their electrical performance requirements are very high. To verify the manufacturing and installation quality of the wires, reduce operational accidents, and improve power supply reliability, performance tests must be conducted.

[0003] A search revealed a Chinese utility model patent, CN219915221 U, which discloses a testing device for high-voltage power testing. The device includes a housing, with a base fixedly mounted on the bottom surface of the housing. Several fixed shafts are fixedly mounted on the upper surface of the base, each fixed shaft having a groove inside. A first bearing is movably mounted inside each groove. A hinge plate is movably mounted on the surface of the housing, and a door is movably mounted on the hinge plate. This utility model works by passing an electric wire through a rubber sheath, then using screws and nuts to fix one end of the wire to the rubber sheath with a first and second fixing block, and fixing the other end to a rotating shaft. Turning on a motor causes the rotating shaft to rotate, stretching the wire. Testers analyze the degree of wire deformation to determine if the test is satisfactory, thus achieving the effect of verifying whether the wire meets standards.

[0004] However, the device lacks the function of detecting the critical value of wire tension, and cannot accurately measure minor damage to the wire during use, resulting in many errors in the actual measurement results. In addition, the device lacks an automatic fixing function, and the wire needs to be fixed manually during use, which is time-consuming, labor-intensive and reduces work efficiency. Summary of the Invention

[0005] The purpose of this utility model is to provide a high-voltage power testing cabinet to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-voltage power testing cabinet includes a cabinet body, a cabinet door fixedly connected to the side wall of the cabinet body, a plurality of fixed seats fixedly connected to the bottom of the cabinet body, a pressure block movably connected to the top of the fixed seats, a telescopic rod fixedly connected to the top of the pressure block, a driving device fixedly connected to the top of the telescopic rod, a plurality of guide rods fixedly connected to the bottom of the driving device, and a lifting plate movably connected to the bottom of the cabinet body.

[0008] Preferably, a measuring groove is provided at the bottom of the cabinet, a movable block is movably connected to the top of the measuring groove, and a limit block is fixedly connected to the top of the movable block.

[0009] Preferably, a scale and a slide are fixedly connected to the bottom of the cabinet, and a positioning block is movably connected inside the slide.

[0010] Preferably, a handle is fixedly connected to the side wall of the cabinet, and several casters are fixedly connected to the bottom of the cabinet.

[0011] Preferably, the top of the lifting plate is fixedly connected to an anti-slip pad, and the top of the fixed seat is fixedly connected to a plurality of anti-slip teeth.

[0012] Preferably, a number of light tubes are fixedly connected to the inner wall of the cabinet.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This high-voltage power testing cabinet, with its fixed base and pressure block, allows for automatic fixing of the wires by placing both ends of the wires into the fixed base and using a drive device to move the pressure block downwards. A guide rod further restricts the movement of the pressure block, increasing its stability during movement and thus achieving automatic wire fixing, thereby improving the device's working efficiency.

[0015] 2. This high-voltage power testing cabinet, through the setting of the lifting plate, allows for adjustment of the tension on the wires after the wires are fixed by adjusting the height of the lifting plate. When the wires have obvious cracks, the height of the lifting plate can be reduced to improve detection efficiency. When the wires have inconspicuous cracks, the height of the lifting plate can be increased to improve the crack detection effect, making them easier to find, thereby improving the detection effect of the device.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0023] A high-voltage power testing cabinet includes a cabinet body 1, a cabinet door 2 fixedly connected to the side wall of the cabinet body 1, several fixed seats 6 fixedly connected to the bottom of the cabinet body 1, a pressure block 9 movably connected to the top of the fixed seats 6, a telescopic rod 10 fixedly connected to the top of the pressure block 9, a drive device 14 fixedly connected to the top of the telescopic rod 10, several guide rods 11 fixedly connected to the bottom of the drive device 14, and a lifting plate 5 movably connected to the bottom of the cabinet body 1. Through the fixed seats 6, pressure blocks 9, etc., in use, by inserting both ends of the wire into the fixed seats 6, the drive device 14 moves the pressure block 9 downwards. The wire is fixed in place, and the movement of the pressure block is restricted by the guide rod 11, increasing the stability of the pressure block 9 during movement. This achieves automatic fixing of the wire and improves the working efficiency of the device. With the lifting plate 5, after the wire is fixed, the tension on the wire can be adjusted by adjusting the height of the lifting plate 5. When the wire has obvious cracks, the height of the lifting plate 5 can be lowered to improve detection efficiency. When the wire has inconspicuous cracks, the height of the lifting plate 5 can be increased to improve the crack effect of the wire, making it easier to detect, thereby improving the detection effect of the device.

[0024] In this embodiment, preferably, a measuring groove 8 is provided at the bottom of the cabinet 1, and a movable block 16 is movably connected to the top of the measuring groove 8. A limit block 17 is fixedly connected to the top of the movable block 16. The change in the length of the wire before and after the high-voltage power test is measured by inserting the wire into the measuring groove 8. At the same time, the movable block 16 fixes one end of the wire inside the measuring groove 8 to facilitate the measurement.

[0025] In this embodiment, preferably, a scale 15 and a slide 7 are fixedly connected to the bottom of the cabinet 1. A positioning block 18 is movably connected inside the slide 7. The positioning block 18 records and assists in the measurement of the wire. At the same time, the scale 15 allows the user to more intuitively observe the changes in the wire.

[0026] In this embodiment, preferably, a handle 3 is fixedly connected to the side wall of the cabinet 1, and several casters 4 are fixedly connected to the bottom of the cabinet 1. The combination of casters 4 and handle 3 facilitates user movement and saves manpower.

[0027] In this embodiment, preferably, the top of the lifting plate 5 is fixedly connected with an anti-slip pad 13, and the top of the fixing seat 6 is fixedly connected with a plurality of anti-slip teeth 12. By setting the anti-slip pad 13 and the anti-slip teeth 12, the fixing effect on the wire is improved, and the wire is prevented from falling off the fixing seat 6 during the test.

[0028] In this embodiment, preferably, a number of lamp tubes 19 are fixedly connected to the inner wall of the cabinet 1. The lamp tubes 19 provide a relatively bright environment inside the cabinet 1 to facilitate the testing and measurement work.

[0029] In this embodiment, a high-voltage power testing cabinet is used by placing both ends of the wire inside the fixed base 6. The driving device 14 moves the pressure block 9 downward to fix the wire, while the guide rod 11 restricts the movement of the pressure block 9, increasing its stability during movement. This achieves automatic fixing of the wire and improves the working efficiency of the device. With the lifting plate 5, after the wire is fixed, the tension on the wire can be adjusted by adjusting the height of the lifting plate 5. When the wire has obvious cracks, the height of the lifting plate 5 can be lowered to improve detection efficiency. When the wire cracks are not obvious, the height of the lifting plate 5 can be increased to improve the crack effect and make it easier to detect, thereby improving the detection effect of the device. The wire is placed inside the measuring slot 8 to measure its length change before and after the high-voltage power test. Meanwhile, the movable block 16 fixes one end of the wire inside the measuring slot 8 for easy measurement. The positioning block 18 records and assists in the measurement of the wire, and the scale 15 allows the user to more intuitively observe the changes in the wire. A handle 3 is fixedly connected to the side wall of the cabinet 1, and several casters 4 are fixedly connected to the bottom of the cabinet 1. The casters 4 and handle 3 facilitate user movement and save manpower. Several lamp tubes 19 are fixedly connected to the inner wall of the cabinet 1, providing a relatively bright environment for the test and measurement work. The top of the lifting plate 5 is fixedly connected to an anti-slip pad 13, and the top of the fixed seat 6 is fixedly connected to several anti-slip teeth 12. The anti-slip pad 13 and anti-slip teeth 12 improve the fixation of the wire and prevent the wire from falling out of the fixed seat 6 during the test.
