Insulating liquids - Unused modified or blended esters for electrotechnical applications
IEC 60312:2019 defines requirements for the characterization of unused modified esters or blends of unused esters used as insulating liquids for electrotechnical applications. It does not cover liquids that contain any proportion of used liquids. The liquids covered by this document are intended mainly for transformer applications. Unused modified/synthetized esters are derived from a natural or synthetic base, or are blends of both. This document covers a variety of ester liquids not covered by other standards specific to natural esters (IEC 62770) or synthetic esters (IEC 61099). As it addresses various categories of liquids, this document also covers a wide range of values for certain performance characteristics. An important property is viscosity, which can affect the design and cooling performance of electrical equipment. A categorization is defined based on the kinematic viscosity of the different liquids. The category of low viscosity ester liquids is established.
Isolierflüssigkeiten - Neue modifizierte oder verschnittene Ester für elektrotechnische Anwendungen
Isolants liquides - Esters neufs modifiés ou mélangés pour applications électrotechniques
L'IEC 60312:2019 définit les exigences relatives à la caractérisation des esters neufs modifiés ou des mélanges d'esters neufs, utilisés comme isolants liquides pour des applications électrotechniques. Il ne couvre pas les liquides contenant une proportion quelconque de liquides usagés. Les liquides couverts par le présent document sont principalement destinés aux applications dans des transformateurs. Les esters neufs synthétiques/modifiés sont dérivés d'une base naturelle ou synthétique, ou sont des mélanges des deux. Le présent document couvre une variété de liquides à base d'esters non couverts par d'autres normes spécifiques aux esters naturels (IEC 62770) ou aux esters synthétiques (IEC 61099). Traitant d'une grande variété de liquides, le présent document couvre également une large plage de valeurs pour certaines caractéristiques de performance. La viscosité est une propriété importante qui peut influencer la conception et les performances de refroidissement du matériel électrique. Une classification est définie sur la base de la viscosité cinématique des différents liquides. La catégorie des liquides à base d'esters à faible viscosité est donc établie.
Izolacijske tekočine - Neuporabljeni modificirani ali mešani estri za uporabo v elektrotehniki
Ta standard določa zahteve za karakterizacijo neuporabljenih modificiranih estrov ali mešanic neuporabljenih estrov, ki se uporabljajo kot izolacijske tekočine za uporabo v elektrotehniki. Ne zajema tekočin, ki vsebujejo kakršen koli delež uporabljenih tekočin. Tekočine, zajete v tem dokumentu, se povečini uporabljajo za transformatorje. Neuporabljeni modificirani/sintetizirani estri so pridobljeni iz naravne ali sintetične osnove ali pa so mešanica obeh. Ta dokument zajema različne tekoče estre, ki niso zajeti v drugih standardih za naravne estre (IEC 62770) ali sintetične estre (IEC 61099). Ker obravnava različne kategorije tekočin, ta dokument zajema tudi širok razpon vrednosti določenih značilnosti delovanja. Pomembna lastnost je viskoznost, ki lahko vpliva na zasnovo in zmogljivost ohlajanja električne opreme. Kategorizacija je določena na podlagi kinematične viskoznosti različnih tekočin. Določena je kategorija za tekoče estre z nizko viskoznostjo.
