Transformer bureau puts detected current situation and new technology

High-pressured equipment bureau puts detected development way

Current, the research of ultrahigh frequency method also is facing a few problems, because measure mechanism and law of pulse electric current to differ, because this cannot undertake inspecting is in putting the demarcate of n, and at present most engineering personnel has been used to be being measured in discharge through inspecting come the serious rate that reflective bureau puts, the transformer product that IEC provides to concerned bureau is put leaves factory in the standard, also the threshold value that carries bureau to the limit of one's capacity sets its index. Current research makes clear, although be in bureau put a source to the circumstance with the transmission changeless way between sensor, of law of pulse electric current inspect the corresponding impact that also did not determine between the pulse signal amplitude that measures in bureau to the limit of one's capacity and place of ultrahigh frequency method, this is more big apply this method to undertake bureau the difficulty that puts ration; In addition, as a result of the complexity of transformer interior insulation system, bureau the transmission of the electromagnetic wave interiorly that puts generation will exist many scattering, fold reflection and attenuation, consequently transmission character studies standoff puts a source to locate the job will be destined is difficulty very big and be full of a challenge.

As the development of science and technology, especially if system of analysis of nerve network, dactylogram, expert, faintness is diagnosed and signal analysis technology divides the increasing application such as form to transformer bureau to put in detecting, get data to passing law of pulse electric current to be measured according to IEC270 standard, undertake pattern recognition and insulation life are evaluated, drive end to put detect technical development. Ultrahigh frequency detects method from what start from digitlization technology namely at the beginning, through transplanting successful traditional method ultrahigh frequency detects in, what implementation bureau puts is successive and online the research that monitor and identifies automatically is obtaining rapid progress, the problem that afore-mentioned ultrahigh frequency laws exist is the task that at present unit of a lot of relevant research needs to solve. The author thinks, a kind of any methods have certain applied limits, it can solve some problems, have a few insoluble. The development of current communication technology makes people realises adequately, online monitoring is an interdisciplinary, omnibus research domain, a variety of method photographs are united in wedlock, move integratedly at present all sorts of technologies are mixed knowledge, compose is built unified, the integrated online platform that monitor, will be prospective bureau is put online monitored development direction.
