摘　　要：针对传统继电器校验仪器接线繁琐、缺陷不易查找的问题,设计了一种基于物联网技术的保护装置用中间继电器校验仪。通过单片机设计了校验仪硬件终端电路,通过设计接口可快速检测继电器动作电压、动作电流和动作时间,并将现场检测数据传回系统后台进行存储。试验测试结果表明所设计的校验仪满足现场使用要求。Aiming at the problems of cumbersome wiring and difficult to find defects of traditional relay calibration instruments,an intermediate relay calibrator for protection device based on Internet of things technology is designed.The hardware terminal circuit of the calibrator is designed based on MCU.The relay action voltage,action current and action time can be quickly detected through the design interface.The on-site detection data shall be transmitted back to the system background for storage.The test results show that the designed calibrator meets the requirements of field use.
