Portable partial discharge ultrasonic cloud detection device

Abstract

The invention discloses a portable partial discharge ultrasonic cloud detection device, which comprises an ultrasonic sensor, a temperature sensor, a humidity sensor, an atmospheric pressure sensor, a signal processing module, a wireless network device, a display and an earphone. The sensor transmits the signal to the signal processing module, and the processed signal is transmitted to the cloud server through the wireless network device, and the signal is subjected to anti-interference processing and characteristic parameters are extracted and stored in the partial discharge signal characteristic database. For analysis, the operator monitors the sound in the earphone and makes a diagnosis based on the results of the cloud server. The diagnosis result is displayed on the monitor, and the device detects and alarms at the same time. The invention uses the data analysis, processing and storage capabilities of the cloud detection principle to detect the partial discharge in the equipment early and prevent the occurrence of major accidents through online monitoring or inspection of the partial discharge of the high-voltage equipment.

Description

technical field [0001] The present invention relates to partial discharge detection technology of high-voltage equipment, in particular to a portable partial discharge ultrasonic cloud detection device, which utilizes the principle of cloud detection, ultrasonic detection and ultrasonic conversion audio principle to monitor the partial discharge of high-voltage equipment online or to the partial discharge of high-voltage equipment Carrying out inspections can detect local defects of equipment early. Background technique [0002] With the rapid and steady growth of the national economy and the rapid development of urban construction, the electricity consumption of enterprises and residents has risen linearly. Today, when market competition is becoming increasingly fierce and electricity is moving from a seller's market to a buyer's market, users have higher and higher requirements for power supply reliability. However, in recent years, high-voltage pillar porcelain insulator...

Problems solved by technology

[0003] At present, most of the existing partial discharge ultrasonic detection devices are based on industrial computers for on-site intrusive monitoring and measurement, and most of them only perform data analysis and calculation for partial discharge signals. Existing empirical facts show that external environmental factors such as temperature, humidity and atmospheric pressure Both have an impact on partial discharge activities, so the misjudgment rate of this type of partial discharge detection equipment is high; in addition, since the analysis and processing of signal data are all carried out in the local device, the data processing capability and data storage capacity of the device All have high requirements, so the efficiency of data analysis and calculation is limited, the cost of hardware is high and the device is large and heavy, and it is inconvenient to carry and transport; secondly, the version upgrade frequency of data processing software is high, which further increases the cost of the device; and because Data and analysis results are stored in the local device, data loss may occur, and its security cannot be guaranteed
