Abstract

A condition on-line monitoring device for medium voltage switchgear is designed.The minimum system of the control circuit is the ADuC842.The parameters such as insulation leakage current

bus temperature

mechanical status

and switch status of switchgear are monitored

which provides the basis and reference for understanding the potential fault and analysis of fault.For the electromagnetic interference existing around the switchgear

from both hardware and software

kinds of anti-interference measures are taken to enhance the electromagnetic compatibility

which makes it successfully pass the national EMC 4 level standards.Research result is of great significance for improving operation reliability of the switchgear

and further security and stability of power system.
