目前,我国对聚光集热器的测试尚未有统一的技术指标。本文提出用标称功率、标称最高温度、平均温度、光机效率、镜面平均贡献及聚光度等六项指标,作为评价聚光器性能的基本指标,并通过焦面能量密度分析对这六项指标进行测定。 这种焦面能量分析法不受任何不确定因素的影响,能直接测出聚光器焦平面上的能量密度分布,是测试聚光器主要性能指标较理想的方法。 根据这一方法研制的焦面能量分析仪,可用于聚光器综合参数的测试。
At present, there is no unified technical index for the test of concentrating collector in our country. In this paper, we use the six indicators of nominal power, nominal maximum temperature, average temperature, machine efficiency, the average contribution of the mirror and the concentration of light as the basic indicators to evaluate the condenser performance, and through the focal surface energy density analysis of these six Item indicators were measured. This method of analyzing focal plane energy is not affected by any uncertainties and can directly measure the energy density distribution on the focal plane of the condenser. It is an ideal method to test the main performance indexes of the condenser. The focal plane energy analyzer developed according to this method can be used to test the parameters of the condenser.
