为了配合高亮度投影管的工作,需要一个直流电压达40kV的高压源——高压倍压块。因倍压块输出电压较高,必须进行绝缘防潮处理,以保证器件可靠地工作。我们将高压倍压块用绝缘材料灌注成一整体的全密封绝缘的器件,制成体积较小,使用安全可靠的直流40kv的高压源。该器件已用在5英寸高亮度阴极射线管投射大屏幕显示器上。 In order to work with high brightness projection tube, you need a DC voltage of 40kV high voltage source - high voltage doubler. Due to the high voltage output voltage clamp, the insulation must be moisture-proof treatment to ensure the reliable operation of the device. We will be high-pressure double-pressure block filled with insulating material into a whole sealed hermetically sealed devices, made smaller, safe and reliable DC 40kv high voltage source. The device has been used in 5-inch high-brightness cathode ray tube projection large-screen display.
