摘　　要：高压母线带电是常见的安全隐患,为监测高压母线,设计了高压母线带电监测系统。该系统运用光纤电压传感器通过波克尔斯原理采集高压母线侧光信号,并通过PIN光电二极管将光信号转换为电信号,将所得的电信号放大取样,最后将数据传入CPLD芯片进行处理并声光报警。利用仿真软件对系统设计做出仿真证明,证实当三相高压母线任意相带电时,都会报警,同时继电器发出不合闸指令,防止事故发生。The high-voltage bus live is a common hidden danger. To monitor the high-voltage bus,a high-voltage bus live monitoring system is designed. This system uses a fiber optic voltage sensor to collect the high-voltage bus-side optical signals through the Pockles principle, and converts the optical signals into electrical signals through a PIN photodiode. Audible alarm. Use simulation software to make a simulation proof of the system design. It is confirmed that when any phase of the three-phase high-voltage bus is charged, the alarm will be issued, and the relay will issue a non-closing instruction to prevent accidents.
