Description

Technical Field

[0001] This utility model relates to the technical field of safety protection devices for partial discharge testing, and in particular to a safety protection device for partial discharge testing. Background Technology

[0002] Partial discharge is a common and potentially hazardous phenomenon during the operation of power equipment. Partial discharge gradually erodes the insulation performance of power equipment, and in severe cases, it can even cause equipment failure, leading to power system paralysis and resulting in huge economic losses and social impacts. Therefore, conducting partial discharge tests on power equipment has become an important means of ensuring the safe and stable operation of the power system.

[0003] However, current partial discharge testing processes face numerous challenges. Partial discharge testing involves hazardous environments such as high voltage and strong electric fields, posing a serious threat to the safety of operators and equipment. Existing safety protection measures are often inadequate and cannot effectively prevent leakage, abnormal discharge, and other situations that may occur during the test. Once an accident occurs, it will cause irreparable damage. Based on this, a safety protection device for partial discharge testing is proposed to solve the above problems. Utility Model Content

[0028] Based on embodiment 1, the drive assembly 21 includes a mounting base 211 fixedly mounted on the top of the fixed base frame 1. A drive motor 212 is fixedly mounted on the top of the mounting base 211. A rotating shaft 213 is fixedly connected to the output end of the drive motor 212.

The protective assembly 23 includes a truss 221. A discharge terminal 226 is fixedly mounted on the front of the truss 221. A clamp 222 is fixedly connected to the inner side of the transmission shaft 217. A rotating wheel 223 is rotatably connected to one end of the inner side of the clamp 222. An adjusting rod 224 is threadedly connected to the inner wall of the bottom of the clamp 222. A clamping block 225 is rotatably connected to the top of the adjusting rod 224.

[0029] In this embodiment, in the connecting mechanism 2, the driving component 21 is the power source for the dynamic adjustment of the entire device; the driving motor 212 is fixedly mounted on the mounting base 211. When the driving motor 212 starts, its output end drives the rotating shaft 213 to rotate, and the transmission wheel 214 on the outer wall of the rotating shaft 213 rotates accordingly; through the transmission belt 215, the transmission wheel 214 transmits power to the transmission wheel 216, thereby driving the transmission shaft 217 to rotate; the rotating shaft 213 and the transmission shaft 217 are respectively rotatably connected to the inner wall of the connecting frame 218, ensuring the stability and reliability of the rotation; the adjusting component 22 is closely connected to the driving component 21 to achieve precise adjustment of the test device; the clamp 222 fixedly connected to the inner side of the transmission shaft 217 is symmetrical. The rotating wheel 223, located on the inner side of the top two sides of the fixed base 1 and on one end of the inner side of the clamp 222, can rotate flexibly, facilitating the placement and movement of the test equipment. When it is necessary to adjust the clamping degree of the test equipment, the adjusting rod 224 is rotated. Since the adjusting rod 224 is threadedly connected to the inner wall of the bottom of the clamp 222, the adjusting rod 224 will move vertically, thereby driving the clamping block 225 connected to the top to move up and down, thus clamping or loosening the test equipment to meet the needs of different specifications of equipment. The discharge end 226, which is fixedly installed on the front of the truss 221, is used to conduct partial discharge tests with the electrical equipment under test. Its position and angle can be adjusted by the coordinated adjustment of the drive component 21 and the adjusting component 22 to achieve the optimal test position.

[0030] Furthermore, the rotating shaft 213 is rotatably connected to the inner wall of the connecting frame 218, and the transmission shaft 217 is rotatably connected to the inner wall of the connecting frame 218; the clamp 222 is fixedly connected to one end of the inner side of the transmission shaft 217, and the clamp 222 is symmetrically arranged on the inner sides of the top two sides of the fixed base frame 1.

[0031] Furthermore, transmission wheel 214 transmits power to transmission wheel 216, which in turn drives transmission shaft 217 to rotate. Rotating shaft 213 and transmission shaft 217 are rotatably connected to the inner wall of connecting frame 218, ensuring the stability and reliability of rotation. Adjustment component 22 is closely connected to drive component 21 to achieve precise adjustment of the test device. Clamping seats 222, which are fixedly connected to the inner side of transmission shaft 217, are symmetrically arranged on the inner sides of the top two sides of fixed base frame 1. The rotating wheel 223 at one end of the inner side of clamping seat 222 can rotate flexibly, which is convenient for placing and moving test equipment. When it is necessary to adjust the clamping degree of test equipment, by rotating adjustment rod 224, since adjustment rod 224 is threadedly connected to the inner wall of bottom of clamping seat 222, adjustment rod 224 will move in the vertical direction, which in turn drives the clamping block 225 rotatably connected at the top to move up and down.

[0032] Working principle: In the connecting mechanism 2, the drive component 21 is the power source for the dynamic adjustment of the entire device; the drive motor 212 is fixedly installed on the mounting base 211. When the drive motor 212 starts, its output end drives the rotating shaft 213 to rotate, and the transmission wheel 214 on the outer wall of the rotating shaft 213 rotates accordingly; through the transmission belt 215, the transmission wheel 214 transmits power to the transmission wheel 216, which in turn drives the transmission shaft 217 to rotate; the rotating shaft 213 and the transmission shaft 217 are respectively rotatably connected to the inner wall of the connecting frame 218, ensuring the stability and reliability of the rotation;

[0033] The adjustment component 22 is closely connected to the drive component 21 to achieve precise adjustment of the test device. The clamp 222, which is fixedly connected to the inner side of the drive shaft 217, is symmetrically arranged on the inner sides of the top two sides of the fixed base frame 1. The rotating wheel 223 at one end of the inner side of the clamp 222 can rotate flexibly, which is convenient for placing and moving the test equipment. When it is necessary to adjust the clamping degree of the test equipment, the adjustment rod 224 is rotated. Since the adjustment rod 224 is threadedly connected to the inner wall of the bottom of the clamp 222, the adjustment rod 224 will move in the vertical direction, thereby driving the clamp block 225 rotatably connected at the top to move up and down, so as to clamp or loosen the test equipment to adapt to the needs of different specifications of equipment. The discharge end 226, which is fixedly installed on the front of the truss 221, is used to conduct partial discharge tests with the power equipment under test. Its position and angle can be adjusted by the coordinated adjustment of the drive component 21 and the adjustment component 22 to achieve the optimal test position.

[0034] The protective component 23 provides safety assurance for the test process; the inner wall of the fixed seat 231 at the top of the middle section of the fixed base 1 is threaded with an adjusting screw 232. By rotating the adjusting screw 232, the measuring scale 233 at the top can be driven to slide on the top of the fixed base 1. The measuring scale 233 can be used to measure the relevant dimensions of the test equipment, providing data support for the adjustment of the adjusting component 22; the hook block 235 fixedly connected to one end of the back of the insulating frame block 234 at the top of the measuring scale 233 can be used to suspend or fix some auxiliary equipment for convenient test operation; the insulating box 236 is fixedly installed on the top of the truss 221, and the conductive springs 237 are fixedly connected to both ends of its inner wall.
