摘　　要：槽式太阳能集热管是槽式太阳能热发电系统中将太阳能转化为热能的核心部件,而其真空失效问题是困扰此类系统的主要技术问题。基于此,本文提出了一种基于气体放电原理的槽式太阳能集热管真空性能无损测试的方法,通过分析槽式太阳能集热管环形空间中气体放电时所产生的光谱特性来判断气体的类型和环形空间内的气体压力,并与通过四极质谱仪残余气体分析系统获得的结果进行了对比验证,最后通过实验证明了该方法的准确性和可行性。The trough solar collector tube is the core component of trough solar thermal power generation system that converts solar energy into heat,its vacuum failure has always been the main technical problem in this kind of system.This paper proposes a non-destructive testing method of the vacuum performance of the trough solar collector tube based on the gas discharge principle.The gas type and pressure in the annular space are judged by analyzing the spectral characteristics of the gas discharge in the annular space of the trough solar collector tube,and the results obtained by the residual gas analysis system of quadrupole mass spectrometer are compared and verified.The accuracy and feasibility of the method proposed in this paper have been proved.
