一、保护电路工作原理该系列彩电保护电路比较复杂,分布在几块电路板上,通过插接件相连接,笔者对保护电路分析整理后,绘制的整体保护电路如图1所示。为方便读者了解保护电路的分布情况,图中画出了各电路板保护电路之间连接插接件的名称和引脚,连接线上的小方框代表连接件,方框旁边为两个互相连接的插接件名称,方框内部为连接线引脚。
First, the protection circuit works The series of color TV protection circuit is more complex, distributed in a few circuit boards, connected through the connector, the protection circuit analysis, finishing, drawing the overall protection circuit shown in Figure 1. In order to facilitate the reader to understand the distribution of protection circuit, the figure shows the name and pin connection connector between the circuit protection circuit, the small box on the connection line represents the connector, next to the box for two mutually The name of the connector to be connected, the inside of the box is the connector pin.
