Product Introduction:

The commonly used methods and instruments for high-voltage equipment discharge detection include visual observation in the visible light range, online detection of leakage current, ultrasonic testing, far-infrared thermography, etc. Visual observation is one of the most commonly used methods, but a large number of electrical equipment accidents occur without visible light, and people often can only hear the "squeaking" corona discharge sound; The principle of ultrasonic detection is to receive the ultrasonic signal emitted by the discharge, convert it into audible sound or other electrical signals, and use multi-point time difference positioning method to determine the position and intensity of the discharge based on the strength of the signal. This method is difficult to intuitively and accurately locate the discharge point at a long distance, especially when there are multiple discharge points simultaneously, making positioning even more difficult. The online monitoring method requires the installation of corresponding measuring equipment in advance, and its investment value is high when used in large quantities, which is not suitable for large-scale promotion and use. Far infrared thermography can detect temperature increases caused by discharge accumulation or internal equipment failures, but this is an indirect measurement method that is difficult to use when the temperature rise is small, rainy or snowy weather, and high-temperature sunlight changes. Especially during surface discharge, a large amount of heat is carried away by the air, and the temperature rise is not obvious, which greatly reduces the accuracy of its detection.
