Description
Technical field
The present invention relates to electric system leakage currents and zero resistance insulator detection field, specifically, are related to a kind of insulation
Sub- leakage current and zero-value detection device.
Background technology
The division (fertilizer making by sludge) of electric system gradation for surface pollution is Electric Design, operation and maintenance and carries out antifouling work
The basic norm of technical management.Guo Wang incorporated businesses standard Q-GDW 152-2006 and IEC60815 is when dividing gradation for surface pollution
The influence that salt is close and ash is close is considered together, based on the close and grey close method come to electric system progress gradation for surface pollution division of salt not
But the method recommended of IEEE and IEC and operation power department of China it is widely used be used for detect insulator contamination degree
Important method, but take and ash close measurement close to salt to insulator to characterize the method for transmission line of electricity pollution level, it is main
Traditional artificial ablution is used, it is necessary to remove part or the whole insulator of string measures, and there are test process is complicated, measurement
Condition is harsh, be easy to cause the problems such as measurement error.Using the method for this sampling and measuring, data collection relatively lags behind
Property, while the limited amount sampled, cause updating for fertilizer making by sludge slow and data imperfect, it is impossible to adapt to intelligent grid
The requirement of development.Supported due to cannot get reliable site pollution degrees of data, many new routes the design phase there may be
External insulating level deficiency problem is often run shortly to need to adjust and be climbed, and causes the waste of manpower and materials or since pollution sources change not
Valid data support is obtained in time, causes grid pollution flashover accident.
Insulator leakage current is the concentrated expression of the factors such as voltage, filth and environmental condition, practice operation experience have shown that：
Leakage current can provide the effective information of more reflection insulator operating statuses, can be used as assessment insulator operating status
With the dynamic parameter of local environment filth state.Therefore by the measurement of insulator leakage current, using the method for mathematical statistics
The function expression between leakage current characteristic value and influence factor is established, with this to running environment filth state residing for insulator
Comprehensive assessment is carried out, has important scientific guidance meaning and engineering application value for the design and operation of transmission line of electricity.
Electric transmission line isolator be subjected to for a long time in operation electromechanical load, atmosphere pollution, expose to the sun and rain, it is cold and hot variation etc. works
With for SI semi-insulation it is also possible to being acted on by Lightning Over-voltage, it is exhausted that these unfavorable factors may cause insulator to occur

The presence of son, the voltage reduction born cause the voltage's distribiuting of bunch of insulator to change, make the dielectric strength of bunch of insulator
It reduces, probability of flashover significantly improves, in some instances it may even be possible to insulator chain be triggered to break the failures such as string, conducting wire landing, cause large-area power-cuts
Wait major accidents.
At present, there are three types of the main stream approach that zero value detection is carried out to insulator：One kind is determination of insulation resistance method, second
It is spark gap method, the third is spread voltage measuring method and infrared imaging method.
Determination of insulation resistance method is higher for detecting zero resistance insulator precision, but detects heavy workload, of high cost, it is impossible into
Row hot line job.
Spark gap method is determine whether by observing the spark of the generation of the air gap between metal steel fork and steel cap
Zero resistance insulator, this method principle is simple, easy to operate, but since the influence factor of gap discharge is more, it is simply a kind of qualitative
Analysis, it is impossible to carry out quantitative analysis；If there are multiple low values or zero resistance insulator in an insulator string, using spark gap method
It may cause the flashover of insulator chain.
Infrared imaging method is to change the method for detecting zero resistance insulator according to Temperature Distribution using thermal infrared imager, but the party
Method relies primarily on experience and knowledge figure is carried out to Infrared image there are certain blindness to carry out insulator zero value detection.By charged
It steps on bar to detect piecewise, the method for zero resistance insulator is determined using insulator chain spread voltage and standard profile voltage is measured relatively
Referred to as potentiometric, this method is easy to operate and the more common method of mesh electric system.
