【Title】The Application of UHF Detection & Positioning Method into the Process of Partial Discharge Detection of Switch Cabinet
【Abstract】Partial discharge detection technology of switch cabinet is widely applied nationwide. It is necessary to judge whether the switch cabinet is abnormal by detecting TEV and ultrasonic signals of switch cabinet at preliminary stage. It is necessary to redetect the abnormal signals with UHF detection technology to judge whether it is discharged, determine discharge type, realize positioning of partial discharge and determine the damage degree of equipment. Based on partial discharge detection case of 10kV switch cabinet of certain transformer substation, the application of UHF detection method into partial discharge detection process of switch cabinet is introduced in this paper.
