我厂过去生产的2.5英寸投影管的投影电视机,由于高压打火,经常烧坏倍压组件中的高压硅堆和高压电容。近年来我们试制黑白高亮度投影电视机,高压单元参照国外线路,采用了一些过压和过流保护措施,使投影电视机的稳定性和可靠性大为提高,试制
Our factory in the past produced 2.5-inch projection tube projection TV, due to high-pressure ignition, often burn the high-voltage components in the double-voltage silicon reactor and high-voltage capacitors. In recent years, we trial production of high brightness black and white projection TV, high voltage unit with reference to foreign lines, using some over-voltage and over-current protection measures to make the stability and reliability of the projection television greatly improved, trial
