摘要
采用传感器技术和数字电路开发出数字式SF_6气体密度在线监测装置,并接入变电站综合自动化系统进行远方、在线监测,解决了机械式密度继电器无法适应无人值班变电站对设备运行状态进行实时监测的问题,有利于断路器状态检修的开展和电网的安全稳定运行。
Adopting the sensor technology and digital circuits, a digital SF6 gas density on-line monitoring device is developed and connected into the integrated automation system of substation to realize remote and on-line monitoring. The new device may efficiently solve the problem that mechanical density relay fails to adapt real-time monitoring of equipment's operation state in a unattended substation. It is beneficial to state-reconditioning of circuit breaker and safe operation of electric networks.
