摘　　要：研制了用于测量换流阀组件电压分布的光电测量系统,以检验其均压效果。该系统主要由探头、光发射装置、光纤传输系统、光电转换装置组成,具有小尺寸、便携等特点。对所设计的光电测量系统进行了频带、冲击电压测试,其带宽为直流至7 MHz。试验结果表明,所设计的测量系统可以有效避免电磁环境干扰,能够满足测量换流阀组件电压分布的需要。To verify the voltage sharing effect of converter valve components, an electro-optical measurement system to measure voltage distribution among converter valve component is developed. This measurement system consists of probes, lighting-emitting devices, optical fiber transmission system and photoelectric conversion devices, and possesses the property of small-size and portability. The bandwidth tests and impulse voltage tests for the designed electro-optical measurement system are performed, and the measured bandwidth is within the range from DC to 7 MHz. Test results show that the designed measurement system can effectively avoid the interference from electromagnetic environment and can meet the demand of measuring voltage distribution among converter valve components.
