摘　　要：针对目前直流输电工程中大量应用的直流断路器,提出一种自动调试的方法,设计了一种测试装置,用于解决直流断路器主支路阀组、转移支路阀组、二极管阀组的工程调试。测试装置包括信息处理模块、光纤脉冲收发模块、采集模块、程控电源模块等部分。测试方法是:通过信息处理模块控制程控电源模块对直流断路器的转移支路阀组、二极管阀组、主支路阀组进行充放电回路的检测;通过光纤脉冲收发模块控制直流断路器相关模组的IGBT(绝缘栅双极型晶体管)通断进行功能测试,包括检测正常控制的功能,检测硬件功能和异常控制的功能,检测软件协议容错能力。测试时专家系统自动比对采集模块实时采集的特征曲线,结合反馈的状态信息,快速检测被测模块硬件电路、定位故障。在张北工程中的实际应用表明该方法能够满足现场验收测试及出厂调试的需要。In view of the numerous DC circuit breakers applied in DC transmission project, an automatic debugging method is proposed, and a testing device is designed for engineering debugging of main branch valve bank, main breaker branch valve bank and diode valve bank of DC circuit breaker. The test equipment includes information processing module, optical fiber pulse transceiver module, acquisition module and program-controlled power module. The test method is to control the program-controlled power module through an information processing module to detect the charging and discharging circuit of the main breaker branch valve bank, diode valve bank and main branch valve bank of DC circuit breaker, and control the relevant modules of DC circuit breaker through optical fiber pulse transceiver module to perform function test of IGBT(insulated gate bipolar transistor). The function test of IGBT includes the function test of normal control for hardware detection and abnormal control for software protocol fault tolerance detection. Combined with the feedback state information collected by optical fiber pulse transceiver module and the characteristic curve collected in real time by the acquisition module, the expert system automatically compares the characteristic curve to achieve the purpose of fast detection of the hardware circuit and fault location, The practical application of Zhangbei project shows that this method can meet the needs of site acceptance test(SAT) and factory acceptance test(FAT).
