一、单相全波高压整流电路我国生产的200～500毫安X线机,都是用四支高压整流管组成全波整流(亦称桥式整流)电路,将高压发生器的交变电压进行整流,变成脉动直流电压加到X线管两端以提高X线机的输出功率。1.整流元件常用的整流元件有高压真空整流管和半导体整流器。高压真空整流管(简称高压整流管)是在高度真空(10~(-6)～10~(-7)毫米汞柱)的玻璃管中装有阴极和阳极
1. Single-phase full-wave high-voltage rectification circuit The 200-500 mAh X-ray machine produced in China uses four high-voltage rectifiers to form a full-wave rectification (also known as bridge rectification) circuit, and the high voltage generator’s alternating voltage Rectification is performed, and a pulsating DC voltage is applied to both ends of the X-ray tube to increase the output power of the X-ray machine. 1. Rectifier components Common rectifier components include high voltage vacuum rectifiers and semiconductor rectifiers. High-voltage vacuum rectifier tubes (high-pressure rectifier tubes for short) are equipped with cathodes and anodes in glass tubes with high vacuum (10~(-6) to 10~(-7) mmHg)
