标准范围

IEC 60312:2019定义了用作电工应用绝缘液体的未使用改性酯或未使用酯的混合物的表征要求。它不包括含有任何比例的用过液体的液体。本文件涵盖的液体主要用于变压器应用。未使用的改性/合成酯衍生自天然或合成碱，或为两者的共混物。本文件涵盖了针对天然酯（IEC 62770）或合成酯（IEC 61099）的其他标准未涵盖的各种酯液体。由于本文档涉及各种类别的液体，因此还涵盖了某些性能特征的广泛值。一个重要的性质是粘度，它会影响电气设备的设计和冷却性能。基于不同液体的运动粘度定义分类。建立了低粘度酯类液体的范畴。

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.
