一、前言随着我国电视事业的兴起,我国投影电视也得到迅速地发展。为了检验和提高投影电视投影管的质量和性能,我所研制出“2.5英寸黑白投影管测试仪”,能比较全面的测试2.5英寸黑白投影管各项光电参数。鉴定会认为,该测试仪性能良好,其高压电源稳定可靠,具有耐(抗)打火能力;亮度测试简便、准确,可以自动描绘调制特性(V_g-I_a)曲线。此外仪器还具有防护x射线的能力。下面仅就几个主要部分做一简要分析。二、投影管测试仪阳极电源
I. Introduction With the rise of China’s television industry, China’s projection television has also been rapidly developed. In order to test and improve the quality and performance of projection TV projection tube, I developed “2.5-inch black and white projection tube tester”, can more fully test the 2.5-inch black and white projection tube of the photoelectric parameters. Identification will be that the tester performance is good, the high-voltage power supply is stable and reliable, with anti (anti) ignition ability; brightness test is simple and accurate, can automatically depict the modulation characteristics (V_g-I_a) curve. In addition the instrument also has the ability to protect x-rays. The following is a brief analysis of only a few major parts. Second, projection tube tester anode power supply
