摘要

针对现有继电器触点性能测试设备对IEC 60255-1标准符合性不足且自动化程度较低的问题，研制了一套遵循该标准的自动化测试系统。提出了以STM32F107VCT6为核心的控制单元，集成光电隔离触点状态监测与示波器电流波形分析技术。设计了RD-TVS分级能量吸收电路以抑制关断过电压。采用模块化硬件架构与分层软件设计，实现了机械耐久、电耐久及闭合电流能力的自动化测试。典型试品的重复测试表明关键参数实测值与理论值相符。该系统实现了继电器触点性能的全自动测试，提升了测试效率与一致性，为触点失效机理研究提供了数据平台。

Abstract

To address the limitations of insufficient compliance with the IEC 60255-1 standard and low automation in existing relay contact performance testing equipment

an automated test system adhering to the standard is developed. A control unit based on the STM32F107VCT6 microcontroller is proposed

integrating opto-isolated contact status monitoring and oscilloscope-based current waveform analysis. An RD-TVS graded energy absorption circuit is designed to suppress turn-off overvoltage. By adopting a modular hardware architecture and layered software design

automated testing of mechanical endurance

electrical endurance

and contact current capability is realized. Repeated testing on representative relay samples shows that the measured key parameters are consistent with theoretical values. This developed system achieves fully automated testing of relay contact performance

enhancing testing efficiency and consistency while providing a data platform for research on contact failure mechanisms.
