Background technology
It is existing that high-tension switch cabinet internal insulating layer can occur insulating barrier cracking, shelf depreciation etc. under the long term such as electricity, heat, environment
As.The failure of high-tension switch cabinet is mostly due to what failure of insulation was caused.Perhaps, the presence of shelf depreciation short time does not interfere with electricity
The dielectric strength of gas equipment, if but high-tension switch cabinet insulating barrier continuously emerges shelf depreciation under working voltage, and these are faint to put
Electricity gradually degrades accumulative effect is produced can the dielectric properties of insulation and expand local defect, and finally result in whole insulation breakdown,
Can cause security incident when serious.
The process of shelf depreciation except along with electric charge transfer and electric energy loss in addition to, can also produce electromagnetic radiation, ultrasound,
Light, generate heat and occur new product etc..Therefore these phenomenons are directed to, the basic skills of partial discharge monitoring has arteries and veins
Rush the methods such as current measurement, ultrasonic measurement, photo measure, chemical measurement, hyperfrequency measurement and UHF measurement.Its middle arteries
Rush current method discharge current pulse information content to enrich, can judge what is discharged by the statistical nature of current impulse and measured waveform
The order of severity, and then understand the situation and its development trend of insulation degradation with modern analysis means, for jump signal reaction
It is sensitiveer, it is easy to accurately and timely to find failure, and be easy to quantitative, therefore, pulse current method is used widely.At present,
The partial discharge monitoring device that domestic many unit is developed is generally in this way extracting discharge signal.The method is by monitoring
Due to the pulse current that shelf depreciation causes in impedance, earth lead and winding, Apparent discharge magnitude is obtained.It is research earliest,
A kind of most widely used monitoring method, is also that monitoring method is put in the office for uniquely having standard (IEC60270) in the world, measured
Information has comparability.Fig. 1 is that (by taking transformator as an example, CT represents that electric current is mutual in figure than more typical partial discharge monitoring
Sensor) theory diagram.But because there is substantial amounts of interference, therefore the sensitivity of the mode such as ultrasonic measurement, photo measure than screen in scene
The sensitivity measured under the laboratory condition for covering is much lower, is really successfully used to the few of monitoring system, and effect is unsatisfactory.
