Research On The Application Of Capacitive Equipment On-line Monitoring Technology And On-line Monitoring Device

Capacitive equipment is an important equipment in the substation, and their safe operation directly affects the safety and stability of power system. To let the equipment actively promote the application of live detection technology, the research and development of online monitoring device, run the test volume the insulation condition of equipment, timely detection of equipment defects and timely arrangements for the repair work, not only can reduce outage time, extended outage of routine test cycle, but also for condition based maintenance to provide in-depth data support. The purpose of this paper is to analyze the principle of relative dielectric loss factor and capacitance of capacitive equipment, and to carry out the research and application of live line detection and on line monitoring device. Through improving the design structure of insulation monitoring device,solving the problems of similar products in the signal transmission and impact resistance,and realize the simple installation, convenient operation and so on. Finally, through the analysis of typical cases of capacitive equipment, summed up the system's data analysis method and the basis for the detection device to provide technical support for the field application.
