I. Introduction
This instrument uses high -frequency detection technology to measure partial discharge, comprehensively use computer technology, ultrasonic, high -frequency, temporary electric wave sampling technology, simulation electronic technology, high -speed Signal acquisition technology and advanced digital signal processing technology, based on the development of Linux operating system platform, provides local discharge two -dimensional, three -dimensional map, amplitude phase spectrum wave shape and discharge signal quantification value. Partial discharge pulse waveforms for detailed observation and analysis, which can better evaluate the local discharge of electrical equipment. It is suitable for daily inspections of high -voltage cables, power transformers and other electrical equipment insulation performance. It has the characteristics of high sensitivity and strong adaptation performance. It can effectively discover its related insulation defects. It is an ideal tool for the state detection when the power equipment is running.
II. Main Functional Characteristics And Indicators
1) The high -voltage electrical equipment can be quickly detected at the site to specially discharge the high -voltage cable. It is convenient to use, the size is small, the weight is light, and it is easy to carry.
2) In the bureau's detection sensor design circuit, with the help of advanced radio frequency signal processing, high -frequency signal processing, and weak signal processing technology, it uses high -precision AD conversion and high -speed digital signal processing chip for digital signal processing. It has good anti -interference performance and measurement Accuracy.
3) Locked by ultrasonic, temporary radio waves, high -frequency, and special high -frequency various methods jointly put signals.
4) A built -in non -contact air sound sensor, which can be configured with an external table sticker ultrasonic sensor.
5) Have a variety of windows such as phase straight lines, PRPD, PRPS to analyze the test data.
6) Support data storage, view, delete and other functions.
7) Support waveform data recording function.
8) Support attention and alarm multi -level threshold settings, and provide intuitive prompts through different values colors.
9) Use large -capacity lithium batteries to power, and one consecutive charging can work for 6 to 8 hours at one consecutive.
10) Use Linux as an embedded operating system to facilitate post -function expansion and fusion of the Internet of Things technology.
