【摘要】 针对目前高压断路器机械参数测试设备抗干扰性能差、无法对多断口同时测量、随机误差较大等问题,提出采用现场可编程门阵列(FPGA)器件与光纤通讯技术结合的新型高压断路器机械参数测试方案。该方案利用FPGA的硬件并行特性可同时测量断路器的多个断口,以消除单片机按拟定顺序测量多个断口所产生的随机误差;利用光纤通讯阻断从断路器到测试仪器的干扰信号通道,提高测试仪的抗干扰能力。经过实际测试,表明此方案具有电路简单、抗干扰性能优良、测试精度较高、便于现场测试等优点。更多还原

【Abstract】 Aiming at the problems of high voltage circuit breaker mechanical parameters test equipment,such as the bad anti-jamming ability,unable to fracture more measured at the same time and the random error is bigger,this peper put forward a new test scheme uing field programmable gate array(FPGA)device combined with the optical fiber communication technology.The scheme can measure multiple fractures of circuit breaker at the same time using parallel characteristic of FPGA,so as to eliminate the random error caused by according to proposed sequence.The scheme can improve the anti-interference ability by using optical fiber communication to block the jamming signal channel from circuit breaker to testing instruments.Actual test shows that the scheme has simple circuit and good anti-jamming performance,high precision,easy to field test,etc.更多还原
