标准摘要
[中文适用范围]： IEC 63044的这一部分除了HBES/BACS设备的产品安全标准之外，还提供了与HBES/BACS网络相关的电气安全要求。它还适用于 HBES/BACS 网络中使用的、不存在特定 HBES/BACS 产品安全标准的设备。此外，它还定义了连接至 HBES/BACS 网络的设备接口的安全要求。它不适用于其他网络的接口。注：其他网络的示例是 IEC 62949 涵盖的专用 ICT 网络。本文件适用于 ?C 操作员站和其他人机接口设备@ ?用于管理功能的 C 设备@ ?C 控制设备@自动化站和应用程序特定控制器@ 现场设备及其接口以及专用HBES/BACS 网络中使用的设备的布线和互连。本文件涵盖以下要求和合规标准： ?防止设备中的危险； ？防止网络过压； ？防止接触电流； ？防止不同类型电路引起的危险； ？保护通信线路免遭电流过大引起的过热。 [外文原描述]： IEC 63044-3:2017 provides the electrical safety requirements related to the HBES/BACS network in addition to the product safety standards for HBES/BACS devices. It also applies to devices used within an HBES/BACS network for which no specific HBES/BACS product safety standard exists. In addition, it defines safety requirements for the interface of equipment intended to be connected to an HBES/BACS network. It does not apply to interfaces to other networks. NOTE An example of other networks is a dedicated ICT network covered by IEC 62949. This document is applicable to operator stations and other human–system interface devices, devices for management functions, control devices, automation stations and application-specific controllers, field devices and their interfaces, and cabling and interconnection of devices used within a dedicated HBES/BACS network. This document covers the following requirements and compliance criteria: protection from hazards in the device; protection from overvoltages on the network; protection from touch current; protection from hazards caused by different types of circuit; protection of the communication wiring from overheating caused by excessive current.
