Abstract

一种采用非阳极高压输入聚焦电位器的彩显用回扫变压器,包括:外壳、骨架、磁芯、线圈、分段串联于高压线圈中的若干高压硅堆、高压滤波电容及聚焦电位器,其特征在于:所述泄放电阻为独立的泄放电阻片,所述聚焦电位器以非阳极高压作为输入电压。其泄放电阻片和高压滤波电容均安装在骨架或支架上,聚焦电位器采用7~15KV的输入电压,体积小,可靠性提高,成本降低10%~30%,广泛适用于彩色显示器、彩电及公用天线系统。
The utility model relates to a flyback transformer for a colour display using a non-anode high voltage input focusing potentiometer, which comprises a housing, a skeleton, a magnetic core, a coil, a plurality of high voltage silicon stacks which are segmented and connected in series in high voltage coils, a high voltage filtering capacitor and a focusing potentiometer. The utility model is characterized in that a discharging resistor is an independent discharging resistance card, and the focusing potentiometer uses a non-anode high voltage as an input voltage; the discharging resistance card and the high voltage filtering capacitor are arranged on the skeleton or a bracket, and the focusing potentiometer adopts the input voltage of 7V to 15KV. The utility model has small size and high reliability, the cost is reduced by 10% to 30%, and the utility model can be extensively used for color displays, color TV sets and public antenna systems.
