一种远程高压电机绝缘测试装置的开发研究

摘要

介绍了一种远程高压电机绝缘测试装置。根据系统需求，独自研发了一种加入了RS-485通信模块和控制模块的新一代电子式电阻表。基于西门子S7-200型PLC对高压电机绝缘监测设备、高压继电器、机械抓进行控制。建立了触摸屏、PLC、绝缘检测仪之间的通讯，实现了高压电机绝缘的远程测量功能。通过运用本装置，提高了高压电机绝缘检测的自动化水平，降低了设备维修频率，并保障了工人的人身安全。%A remote insulation test device for high -voltage electrical motors is introduced. To meet system requirement, a new -generation electronic insulation tester incorporating RS -485 communication module and control module was independently developed. Based on Siemens S7-200 PLC the system can control high-voltage motor insulation monitoring devices, high voltage relays and mechanical grips. Communication between the touch screen, PLC and insulation tester was established, realizing remote insulation measurement for high voltage motors. The device improves the automation level of high-voltage motor insulation test, reduces the frequency of equipment maintenance and ensures personal safety.
