(Main)Bushings for DC application
Bushings for DC application
This International Standard applies to outdoor and indoor bushings of any voltage used on DC
systems, of capacitance graded or gas insulated types for use as components of oil-filled
converter transformers and smoothing reactors, as well as air-to-air DC bushings. This
standard does not apply to the following:
• cable terminations (potheads);
• bushings for instrument transformers;
• bushings for test power supplies;
• bushings applied with gaseous insulation (other than air at atmospheric pressure) external
to the bushing;
• bushings for industrial application;
• bushings for traction application;
• bushings for distribution class transformers.
This standard makes reference to IEC 60137 for general terms and conditions and defines the
special terms used, operating conditions, ratings, test procedures as well as general
mechanical and electrical requirements for bushings for DC application.

Skoznjiki za enosmerne aplikacije
Ta mednarodni standard se uporablja za zunanje in notranje skoznjike katere koli napetosti, uporabljene v sistemih enosmernega toka, z razredom kapacitivnosti ali plinsko izolacijo za uporabo v komponentah z oljem napolnjenih usmerniških transformatorjev in izravnalnih reaktorjev ter tudi za zračne skoznjike za enosmerne aplikacije. Ta standard se ne uporablja za:
• kabelske priključke (razdelilnike);
• skoznjike za merilne transformatorje;
• skoznjike za preskusno napajanje;
• skoznjike za plinsko izolacijo (razen zraka pri atmosferskem tlaku), nameščeno zunaj skoznjika;
• skoznjike za industrijsko uporabo;
• skoznjike za vlečno uporabo;
• skoznjike za transformatorje razdelilnega razreda.
Ta standard se glede splošnih določil in pogojev sklicuje na standard IEC 60137 ter določa uporabljene posebne pogoje, delovne pogoje, značilnosti, preskusne postopke ter tudi splošne mehanske in električne zahteve za skoznjike, ki se uporabljajo za enosmerne aplikacije.

BUSHINGS FOR DC APPLICATION
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation.
IEEE Standards documents are developed within IEEE Societies and Standards Coordinating Committees of the
IEEE Standards Association (IEEE-SA) Standards Board. IEEE develops its
