高功放高压联锁电路改进与测试

高压联锁性能的好坏直接影响设备能否正常工作。通过分析CPI高功放（HPA）的延时加高压程序、高压联锁电路和交流延时器工作原理,研究出一种新改进的高压联锁电路方案和用于交流延时器的测试方法。分析阐述表明,该方案和测试方法克服了CPI高功放的高压联锁方案的弊端。另外,根据分析结果设计了延时测试电路,它可对交流延时器性能参数进行定量测试。

Improvement and test of high power amplifier high voltage interlock circuit

Whether the device can work regularly was determined by the performance of high voltage interlock directly.Through the operating principle analysis of high voltage interlock circuit and AC time delayer of high power amplifier based on CPI mechanical cabinet,an improved high voltage interlock circuit solution and a test method applied in AC time delayer are studied.The improved interlock circuit overcomes the drawbacks of original high voltage interlock solution.The designed test circuit can carry out quantitative test of AC time delayer parameters.
