7.4 IfcElectricalDomain(电气领域)
7.4.1 架构定义
IfcElectricalDomain schema 是 IFC 模型领域层的一部分。它扩展了 IfcSharedBldgServiceElements schema 中概述的建筑服务系统概念。它定义了电缆系统概念,其中电缆传输电力、数据、电话信号或其他形式的电缆传输。
此外,该 schema 还定义了通过电缆连接的各种设备、电气设备的保护、灯具在建筑物内的提供和概念,以及电缆本身以及支撑和敷设电缆的方法。
IfcElectricalDomain 的范围定义如下:
- 用于电力分配和照明、数据、电信、安全、信号、控制和视听目的的电缆系统,
- 此类系统中使用的设备,
- 设备与电路、配电点等的连接,
- 电气装置的稳态运行,
- 灯具(装置),它们的类型以及为实现照明计算提供物理上准确照度所需的信息。
请注意,对于电气系统,该 schema 的特定范围是根据伏特 (V) 和交流电 (AC) 或直流电 (DC) 的低压电气装置,从 12V (AC/DC) 到 1000V (AC) 或 1500V (DC),根据 ISO/IEC 定义,其中范围内的装置被认为从公共事业供电终止的电表或电压降至范围内的低压范围的变压器开始。
其他电气系统,包括特低压、中压和高压,可以使用此 schema 指定,但这些系统的规定尚未得到具体提供。
同样,虽然电气领域 schema 可用于数据、电信、安全、信号、控制和视听目的,但这些类型系统所需的具体规定尚未在模型中完全捕获和阐述。
IfcElectricalDomain schema 支持以下类型的理念:
- 视听设备,
- 电缆桥架配件(用于线槽、电缆托盘、电缆槽和电缆梯),
- 电器设备,
- 电动机,
- 配电盘,
- 发电机,
- 接线盒,
- 灯具,
- 灯泡,
- 插座,
- 保护装置,
- 保护装置脱扣单元,
- 开关设备,
- 变压器,
以下项目在范围内但未详细阐述:
- 1000V AC 和 1500V DC 以上的中高压装置
- 电压低于 12 伏 (AC/DC) 的系统
- 视听系统
- 电信系统
- 数据系统
- 信号和控制系统的电缆
- 电缆桥架(电缆梯)
- 计算机网络电缆和网络设备
以下项目目前被视为超出 IfcElectricalDomain schema 的范围:
- 公共事业供电服务
- 电气装置的非稳态/瞬态运行状态
- 与电气装置安全相关的安全安排
- 自动化设备或总线系统之间的通信信号
- 传感器(在 IfcBuildingControlsDomain schema 中处理)
- 聚光镜系统,即聚光灯指向远处反射镜以分配光能(除非作为单独定义的对象的组)
- 专业用途的照明(例如,舞台、绘画)
电气回路由连接在一起的电气设备和电力电缆组成。在 IFC4 之前,电气回路的实例被定义为 IfcElectricalCircuit(IfcSystem 的子类型)。此定义已在 IFC4 中删除。现在,通过 IfcDistributionSystem.PredefinedType::IfcDistributionSystemEnum 以及特定的属性集来识别电气系统以及其他电缆系统和其他形式的配电系统。
