6 产品技术文件用图形符号的设计.第3部分:连接节点、网络及其编码的分类 - 摘要

This part of International Standard 81714 specifies primarily requirements concerning the classification of connect nodes assigned to graphical symbols, being a representation of functional and product concepts. Due to the strong interrelation between the product and its corresponding graphical representation, identical classification principles are applied for both the classification of connect nodes of products as well as for the classification of networks and their representation by graphical symbols in computer-aided systems.

9 欧洲标准EN 50160的应用指南 - 摘要

It is important to note that the scope of the standard is confined to the electricity supplied at the supply terminals, and does not deal with the supply system or the customer´s installation or equipment. The diagram below in Figure 1 illustrates the point which is defined in EN 50160 as the supply terminals and also the relationship between the impulse withstand requirements of the supply terminals, the customers installation and the customers electrical equipment. The appropriate categories of impulse voltage withstand for each zone are also highlighted. It should be stressed that the supply terminals, referred to in both the standard and this application guide,and the origin of the installation, referred to in both IEC 60664-1, Insulation coordination for equipment within low-voltage systems, and IEC 60364-4-44, Electrical Installations of buildings Part 4 Protection for Safety Chapter 44 Protection against overvoltages, are one and the same point.Figure 1 – Illustration of location of supply terminals As the standard is intended to deal only with the characteristics of the voltage at specified points on the public distribution networks, it does not deal directly with the characteristics of networks themselves, such as short circuit power. Clearly, however, the network characteristics will have an effect upon the magnitude of several of the phenomena described by the standard.The standard is applicable only under normal operating conditions of the supply system. This includes also the correct operation of protection devices in the case of a fault in the network;the operation of loads agreed between customer and distribution network operator and changes in network configuration.When energy is supplied to the public networks from small private generators, it is important to keep the level of disturbances within acceptable limits. In this context private generation is in the same position as any customers installation and therefore has to comply with the related emission standards and agreed limits for the voltage supplied. As such the voltage supplied from the generator must comply with the requirements of EN 50160.Table 1 – Non-exhaustive list of exceptional conditions and examples
