标准摘要
[中文适用范围]： 本文件规定了用于吸收聚光太阳能并将热量传递给线性聚焦太阳能集热器中流体的太阳能热接收器的技术要求、测试、耐久性和技术性能参数。所涉及的接收器由吸收管和绝缘玻璃套筒管组成。 注1 本文件中包含的大多数测试方法适用于抛物槽和菲涅耳集热器太阳能热电厂的太阳能接收器。 本文件包括技术特性的定义、几何和性能参数的表征，以及光学特性、热损失和耐久性的测试方法。 注2 目前关于接收管的不同测试方法的经验积累不足以确定哪种测试方法最好；本文件描述了目前可用的所有不同方法，没有定义推荐的方法。 为了清楚起见，这里说明本文件中描述的热损失测试不提供接收管在商业太阳能场中安装时的热损失。 室内单个接收器测试获得的热损失明显低于商业太阳能场室外实际运行条件下的热损失。然而，本文件中描述的室内测试程序适用于接收管性能比较。 太阳能场设计考虑的热损失是通过测试在实际太阳能条件下运行的完整集热器获得的。 [外文原描述]： IEC TS 62862-3-3:2020 specifies the technical requirements, tests, durability and technical performance parameters of solar thermal receivers for absorbing concentrated solar radiation and transferring the heat to a fluid used in concentrated solar thermal power plants with linear-focus solar collectors. The receivers addressed consist of an absorber tube and an insulating glass envelope tube. This document includes the definitions of technical properties and characterization of geometry and performance parameters as well as the test methods for optical characterization, heat loss, and durability. For the sake of clarity, it is stated here that the thermal loss tests described in this document do not deliver the thermal loss of the receiver tubes when they are installed in commercial solar fields.
