MSJF-3003BUltrasonic partial discharge tester
The acoustic-infrared version utilizes microphone array technology to collect sound wave data and combines it with a high-definition camera to achieve sound wave localization.
Beamforming is used to analyze the sound wave localization technology to obtain sound wave distribution data, which is then fused with video to generate a sound image cloud map and dynamically displayed on the screen.
It can be widely used in partial discharge detection of power systems, including insulation status detection of high-voltage switchgear, ring network cabinets, voltage/current transformers, transformers (including dry-type transformers), GIS, overhead lines, cables, and other equipment. The discharge degree of electrical equipment is measured by the following indicators: Partial discharge intensity detection: By measuring the discharge signal within one power frequency cycle, the intensity of partial discharge is characterized by the maximum value (dB) in the discharge pulse sequence.
◇ Product Features
The acoustic imaging module is developed to cooperate with power system inspection robots, drones, online monitoring, and other application scenarios, and can adapt to various occasions. Once a gas leak occurs, the acoustic imaging module can sense the ultrasonic waves/sound waves generated during the gas leak, thereby locating the leak point and triggering an alarm.
This function is based on acoustic imaging technology, using a microphone array to scan spatial sound waves, and determining the fault location through the phase difference of the sound waves to obtain a "sound image."
