Description
Technical field
The present invention relates to power equipment operating statuses to overhaul field, and in particular to a kind of composite insulator ultra-wide band radio-frequency biography
Feel intelligent fitting and its application method.
Background technique
Composite insulator makes up because its is light-weight, intensity is high, resistance to pollution flashover performance is strong, manufactures many merits such as easy to maintain
The deficiency of porcelain and glass insulator, in power grid using more and more extensive.Currently, used in the nationwide integrated power grid it is compound absolutely
Edge subnumber amount is up to millions of, and runing time is longest more than 20 years.The main component of composite insulator sheath is silicon
Rubber, when being chronically exposed in outdoor environment, silicon rubber by solarization, drench with rain, high temperature, severe cold, husky erosion, acid etching, strong electrical field etc.
Physics chemical action, polymer chain such as are gradually decomposed and volatilize at the variation, and performance gradually declines, and composite insulator is caused to go out
The features such as existing dusting, hardening, cracking, galvanic corrosion damage, hydrophobicity loss, so that with the increase of the service life, composite insulator is resistance to
Pollution flashover degradation, insulating reliability reduce.Meanwhile composite insulator is not conforming to standard operation or the meeting in During Process of Long-term Operation
There is mechanical strength decline, the problems such as fitting loosens, sour gas intrusion, the plug of composite insulator is caused to fall off or crisp
It is disconnected.Therefore, it needs to detect composite insulator in actual use, to guarantee safety that composite insulator uses and reliable
Property.
Currently, domestic and international researcher has carried out numerous studies to composite insulator detection technique, it can by detection operation mode
It is divided into contact and two kinds contactless.The former includes short-circuit fork method or spark gap method, Photoelectric Detection bar method, electric field measurement
Method, pulse current method, leakage current method etc.；The latter includes ultraviolet image method, infrared thermal imagery method, ping method, laser-Doppler
