电力变压器第24部分:调压配电变压器规范

[中文适用范围]： 本文件适用于额定容量从 25 kVA 到 3 150 kVA 的中功率变压器，最高设备电压最高达 36 kV，或在低压网络中最高设备电压高达 1.1 kV，并配备电压调节装置。电压调节配电变压器是配备了用于控制初级或次级电压以实现负载调压目的的组件的变压器。安装 VRDT 的主要目标是调节低压网络电压水平（即 400 V），以避免违反相关标准或法规规定的限值。VRDT 必须能够正确作为降压和升压变压器运行。本文档涵盖的变压器符合 IEC 60076（所有部分）的相关规定，除非本文档另有规定，否则也符合欧洲标准 EN 50160 和 EN 50588-1。 [外文原描述]： IEC 60076-24:2020 applies to medium power transformers from 25 kVA up to 3 150 kVA with highest voltage for equipment up to 36 kV, or in low voltage (LV) networks with highest voltage for equipment of up to 1,1 kV equipped with voltage regulating devices. Voltage regulating distribution transformers are transformers equipped with components to control primary or secondary voltage for on-load voltage regulation purposes. The main objective of the installation of a VRDT is to regulate the LV network voltage level (i.e. 400 V), to avoid violation of the limits defined by relevant standards or regulations. The VRDT must operate properly as a step down and step up transformer. Transformers covered by this document comply with the relevant requirements set out in IEC 60076 (all parts) and, unless otherwise stated in this document, they also comply with European Standards EN 50160 and EN 50588-1.
