Description

Technical Field

[0001] This utility model relates to partial discharge detection technology, and in particular to an airborne multifunctional partial discharge detection device. Background Technology

[0002] Currently, most partial discharge detection devices on the market are portable. To address partial discharge detection in complex terrain areas, some devices are being integrated and mounted on drones for detection at high altitudes, in mountainous regions, and in locations inaccessible to human personnel. However, current mounted partial discharge detection devices only utilize either acoustic or electromagnetic wave methods, and require favorable weather conditions. This type of technology has the following main drawbacks:

[0003] Southern regions experience frequent rainfall, and the weather changes rapidly between sunny and rainy conditions. Drones have an IP55 waterproof rating, meaning they cannot be used during heavy rain. Furthermore, ultrasonic waves are affected by environmental factors during heavy rain, and drones cannot be used during thunderstorms. Summary of the Invention

[0004] To address the shortcomings of the existing technical solutions, this utility model provides an airborne multifunctional partial discharge detection device.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An airborne multifunctional partial discharge detection device includes an ultrasonic detection unit, and the airborne multifunctional partial discharge detection device further includes:

[0007] A drone and a three-axis gimbal, wherein the three-axis gimbal is connected to the drone;

[0008] A first housing and an electromagnetic wave detection unit, wherein the first housing is connected to the three-axis gimbal, the electromagnetic wave detection unit is disposed inside the first housing and connected to the first antenna, and the ultrasonic detection unit is disposed on the first side wall of the first housing;

[0009] Multiple interfaces and a sealing unit are provided, wherein the multiple interfaces are disposed on the second side wall of the first housing, and the sealing unit surrounds the multiple interfaces and is attached to the second side wall.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. Highly adaptable;

[0012] By integrating the ultrasonic detection unit and the electromagnetic wave detection unit, and through experimental testing by the Electric Power Research Institute, it was found that different discharge types have different responses to acoustic wave testing and electromagnetic wave testing. Therefore, the combined acoustic and electromagnetic testing is the best choice for detection: the electromagnetic wave detection unit is used for detection on rainy days, and the ultrasonic detection unit is used for detection on sunny days, which is adapted to different weather conditions.

[0013] 2. The test results are accurate;

[0014] During normal testing, various discharge phenomena may occur in the circuit and equipment. When this equipment uses ultrasonic testing, it can take pictures to locate the problem points. Then, the operator can control the drone gimbal to rotate 90 degrees and use electromagnetic wave high frequency to perform a second test. Ultrasonic and ultra-high frequency testing are performed simultaneously, making the test more comprehensive.

[0015] 3. High operational reliability;

[0016] The use of sealing units enables waterproofing of multiple interfaces, improving the reliability of the device's operation. Attached Figure Description
