BS EN 50397-3:2022 额定电压高于交流 1kV 且不超过交流 36kV 的架空线路用被覆导线及相关附件 使用指南

1   Scope This part of EN 50397 provides general recommendations for the selection, storage, transportation and installation of the covered conductors and the related accessories specified in EN 50397‑1 and EN 50397‑2, unless otherwise specified. Safety regulations and environmental regulations as well as rules for installation and mechanical design are not considered in this Guide to use, as they are covered by relevant national regulations and laws. Relevant national regulations are not considered in this guide, but it is advised that they are always consulted as appropriate. NOTE The term “national regulations” is used throughout this guide. It can include specific safety regulations, rules of installation and other relevant instructions which, depending upon the particular country or district, can exist in a legislative (mandatory) form, or as a non-mandatory code of practice. In addition, certain specific utilities can have their own safety practices. It is assumed that the design of installations, the purchase and installation of covered conductors and of the related accessories specified in this document are entrusted to suitably skilled and competent people. In case of doubt as to the suitability of covered conductors and the related accessories for a particular use, further specific information is expected to be obtained from the manufacturer.

BS EN 50341-2-22:2022 交流电压超过 1kV 的架空电线 波兰国家规范方面(NNA)（基于 EN 50341-1:2012）

1   Scope 1.1   General (ncpt) PL.1 Scope of application This NNA applies to designing and constructing of new overhead lines with nominal system voltages exceeding 1 kV AC. “New overhead line” means a totally new line between two points, A and B, built up with new components. The standard PN‑EN 50341‑1 (Part 1) with this NNA does not apply to modernisation, reconstruction and renovation of the existing lines, unless otherwise specified in the Project Specification.

GSO IEC TR 60865-2:2022 短路电流 影响计算 第2部分：计算示例

IEC TR 60865-2:2015(E) shows the application of procedures for the calculation of mechanical and thermal effects due to short circuits as presented in IEC 60865-1. Thus, this technical report is an addition to IEC 60865-1. It does not, however, change the basis for standardized procedures given in that publication. This second edition cancels and replaces the first edition published in 1994 and constitutes a technical revision. It includes the following changes. The determinations for auto reclosure together with rigid conductors have been revised. The configurations in cases of flexible conductor arrangements have been changed. The influence of mid-span droppers to the span has been included. For vertical cable-connection the displacement and the tensile force onto the lower fixing point may be calculated now. Additional recommendations for foundation loads due to tensile forces have been added. The subclause for determination of the thermal equivalent short-circuits current has been deleted (is part of IEC 60909-0:2001 now). The standard IEC 60865-1:2011 has been reorganized and some of the symbols have been changed to follow the conceptual characteristic of international standards.
