Z oljem polnjena električna oprema - Vzorčenje plinov in analiziranje prostih in raztopljenih plinov - Napotek

Ta mednarodni standard obravnava tehnike za vzorčenje prostih plinov iz plinskih relejev močnostnih transformatorjev. Opisane so tri metode za vzorčenje prostih plinov. Ta standard ne zajema tehnik za vzorčenje olja iz opreme, polnjene z oljem, kot so močnostni in instrumentni transformatorji, dušilke, skoznjiki, oljni tlačni kabli in oljni kondenzatorji za nihajni krog; opisane so v točki 4.2 standarda IEC 60475:2011. V olju raztopljeni plini se pred analizo ekstrahirajo iz olja. Opisane so tri osnovne metode, prva z ekstrakcijo v vakuumu (Toeplerjeva črpalka in delno razplinjevanje), druga z nadomeščanjem raztopljenih plinov z vpihavanjem nosilnega plina v vzorce olja (odparevanje) in tretja z ločitvijo plinov med vzorcem olja in majhno količino nosilnega plina (plinska faza). Po ekstrakciji s plinsko kromatografijo se plini kvantitativno analizirajo; opisana je analizna metoda. Prosti plini iz plinskih relejev se analizirajo brez predhodne obdelave. Prednostna metoda, s katero se zagotovi zmogljivost opreme za ekstrakcijo plina in analizo, obravnavane kot enoten sistem, je razplinjevanje vzorcev olja, ki so bili pripravljeni v laboratoriju in vsebujejo znane koncentracije plinov (»standardi za plin v olju«), ter kvantitativna analiza ekstrahiranih plinov. Opisani sta metodi za pripravo standardov za plin v olju. Za dnevna preverjanja kalibracije kromatografa je primerno uporabiti standardno mešanico plinov, ki vsebuje znane količine plinskih sestavin v razmerju, podobnem povprečnim razmerjem plinov, ekstrahiranih iz transformatorskih olj. Opisane tehnike na eni strani upoštevajo težave, značilne za analize v zvezi s preskušanjem sprejemljivosti v tovarni, kjer je vsebnost plinov v olju običajno zelo nizka, na drugi pa tudi težave, ki jih nadzorna oprema povzroča na terenu, če se vzorci prevažajo s tovornim letalom, na katerem se tlak ne uravnava, ali se temperaturi prostora obrata in preiskovalnega laboratorija znatno razlikujeta.

Foreword
The text of document 10/849/FDIS, future edition 4 of IEC 60567, prepared by IEC/TC 10 "Fluids for
electrotechnical applications" was submitted to the IEC-CENELEC parallel vote and approved by
CENELEC as EN 60567:2011.
The following dates are fixed:
(dop) 2012-08-24
• latest date by which the document has
to be implemented at national level by
publication of an identical national
standard or by endorsement
(dow) 2014-11-24
• latest date by which the national
standards conflicting with the
document have to be withdrawn
This document supersedes EN 60567:2005.
EN 60567:2011 includes the following significant technical changes with respect to EN 60567:2005:
Since the publication of EN 60567:2005, CIGRE TF.D1.01.15 has made progress in several areas of
dissolved gas analysis (DGA), notably
a) oil sampling,
b) laboratory analysis and solubility coefficients of gases in non-mineral oils,
c) calibration of the headspace gas extraction method,
d) more sensitive detectors for chromatography,
e) preparation of air-saturated standards and
f) evaluation of gas monitor readings.
These advances are included in EN 60567:2011.
Sampling of oil for DGA from oil-filled equipment has been moved from EN 60567 to EN 60475 as
reflected in the revised title of this standard.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such patent
rights.
