Research On Application Situation Of Partial Discharge On-line Monitor Technology

This paper mainly introduced the present application situation of on-line monitor technology.The effective detection of partial discharge is of great significance for the safe and stable operation of the power equipment.However, the scene of the on-line monitoring technology application situation is not ideal.In recent years in the field operation, mainly reflects the following problems:some installation high rate of false positives.Part of the device failure rate is high, short service life, maintenance workload;Part of the device real-time performance;The hardware and software quality problems;Technology standard is not perfect;Use of online monitoring data and analysis was not enough.The on-line monitor technology passes through dozens of years research and the practice, has discovered many main equipment flaws, has displayed the positive role for the equipment safe operation. But at present,it’s application still needs more experience, but this kind of technical’s mature application for the electricity advocated strongly the equipment the safe operation construction strong security in advance controlled the defense line will be without a doubt together.This paper is based on the excavation site, such as by comparing the characteristics of thefield detection, and put forward the "scheme of detection by using preset" portable charged detection probe and combined, and the feasibility of the solution is analyzed.It should analysis of how to carry out the on-site data accumulation of samples more effectively, and discuss the analysis and the research of on-line monitoring data.In view of the serious false alarm, this paper will explore the "the dynamic balance between leakage alarm and false alarm".In the transformer substation under the ideal conditions, It should discuss the characteristics of field phase acquisition method, and study how to carry out accurate phase calibration.
