Description

Technical Field

[0001] This utility model relates to the field of GIS equipment defect detection technology, specifically a GIS equipment defect detection device that is easy to install. Background Technology

[0002] Gas-insulated fully enclosed switchgear (GIS) equipment is a complex structure consisting of circuit breakers, disconnect switches, grounding switches, instrument transformers, surge arresters, busbars, connectors, and outgoing terminals. It is filled with SF6 insulating gas, making disassembly and maintenance relatively difficult, technically demanding, time-consuming, and resulting in significant losses due to power outages.

[0003] Analysis of past GIS equipment accidents reveals that most serious incidents, such as breakdowns and burnouts, stemmed from early defects that were not detected using existing detection methods. Combining partial discharge monitoring of GIS equipment, expert databases, and field experience allows for a general assessment of the type of partial discharge and rough location, but pinpointing the detailed internal faults of the GIS equipment remains impossible.

[0004] Visual inspection of GIS equipment is a method that enables multi-directional perspective imaging of GIS equipment in a short time. Combined with specialized image processing and interpretation technologies, it achieves "visualization" of its internal structure and rapid diagnosis of its quality status, greatly improving the accuracy of fault location and diagnosis, and increasing fault diagnosis efficiency. It provides a novel inspection method for the safe and quality monitoring of the entire facility, featuring safety, portability, ease of use, reliability, maintainability, and scalability. Furthermore, it proposes corresponding strategies and measures to address the potential hazards, scope, and extent of partial discharge from GIS equipment, which is of great significance to the safe, stable, and economical operation of the power grid.

[0005] The State Grid Corporation of China first used a CR inspection system to analyze the internal structure of GIS equipment, which can clearly display the internal defects of GIS equipment and obtain a large amount of image information. At the same time, it designed a non-destructive testing device capable of mobile imaging and gave CR inspection technical standards.

[0006] A DR imaging system, jointly designed by China Southern Power Grid and North China Electric Power University, can analyze the internal structural information of GIS equipment. It displays internal defects using both defect simulation and on-site device inspection, establishing the detection range of DR technology in power installations. During the experiment, the X-ray machine in the DR imaging system was set under different voltage, current, time, and focal length conditions to analyze the detection of power installations, establishing the detection requirements for disconnect switches, circuit breakers, and busbars, as well as the detection parameters for focal length and exposure of these devices.

[0007] In the process of researching CR or DR systems in my country's power system, a common approach is to place some defects inside the power installations to observe whether X-rays can capture images of the defects. At the same time, this is combined with DR inspection equipment to judge the accuracy of non-destructive testing technology. The analysis results are beneficial to the future inspection of electrical installations and improve the safety of the equipment.

[0008] Currently, when inspecting GIS equipment for defects, tripods are typically used to mount X-ray machines. X-ray machines usually weigh tens of kilograms. To achieve sufficient stability, the area enclosed by the three legs of the tripod on the ground must be large enough. However, due to the complex structure of GIS equipment, sufficient space is often unavailable on-site to accommodate the tripod, leading to instability. Furthermore, a separate set of brackets is required to mount the DR imaging panel, necessitating at least two sets of brackets, which adds considerable inconvenience to both transport and on-site setup.

The easily installable GIS equipment defect detection device according to claim 1, characterized in that: The aforementioned hanging arm assembly includes a front hanging arm and a rear hanging arm. Both the front hanging arm and the rear hanging arm include two arc-shaped curved arms. One end of each of the two arc-shaped curved arms is detachably and fixedly connected to form a C-shaped hanging arm with the opening facing downward. The front and rear C-shaped hanging arms are detachably and fixedly connected to each other and are mounted on the cylinder of the GIS equipment to be tested.

3. The easily installable GIS equipment defect detection device according to claim 2, characterized in that: The two curved arms are provided with through holes at their close ends, and a first crossbar passes through the through holes on the front and rear sides in sequence and extends out.

4. The easily installable GIS equipment defect detection device according to claim 3, characterized in that: Both ends of the first crossbar are provided with a first threaded section. On the first threaded section at both ends, a first locking nut is screwed on the front and rear sides of the corresponding C-shaped hanging arm. Tightening the first locking nut locks the corresponding C-shaped hanging arm to one end of the first crossbar.

5. The easily installable GIS equipment defect detection device according to claim 4, characterized in that: Each of the arc-shaped curved arms is provided with an upper through hole and a lower through hole, and a second crossbar and a third crossbar are respectively passed through the upper through hole and the lower through hole from front to back and extend out.

6. The easily installable GIS equipment defect detection device according to claim 5, characterized in that: Both ends of the second crossbar and the third crossbar are provided with second threaded sections. On the second threaded sections at both ends, second locking nuts are screwed onto the front and rear sides of the corresponding arc-shaped curved arms. Tightening the second locking nuts locks the corresponding arc-shaped curved arms to one end of the first crossbar.

7. The easily installable GIS equipment defect detection device according to claim 5, characterized in that: Both the first support assembly and the second support assembly include a support plate. One side of the support plate is detachably fixed to the third crossbar, and the other side of the support plate is connected to a retaining sleeve via a rope. The retaining sleeve has a notch on its bottom side and is engaged with the second crossbar.

8. The easily installable GIS equipment defect detection device according to claim 7, characterized in that: The bottom surface of the support plate has a slot for engaging the third crossbar on the side facing the third crossbar, and the slot is arranged along the width direction of the support plate.

9. A GIS equipment defect detection device that is easy to install according to claim 7, characterized in that: The X-ray machine emitter is placed on the support plate of the first support assembly, and the upper surface of the support plate of the second support assembly is provided with a slot arranged along its width direction, and the bottom end of the DR imaging plate is inserted into the slot.

10. A GIS equipment defect detection device that is easy to install according to claim 1, characterized in that: The GIS equipment defect detection device also includes an X-ray controller and a computer. The X-ray controller is mainly used to provide power to the X-ray machine and control the X-ray machine to work. The computer communicates wirelessly with the DR imaging panel and is mainly used to receive image information transmitted back by the DR imaging panel.
