变电二次继电保护状态检修应用研究

Application Research on Condition Maintenance of Secondary Relay Protection in Substation

变电二次继电保护状态检修就是以保护装置为对象,评估装置的运行状态。转变传统定期检修的模式,按照设备运行状态进行状态检修,在设备性能出现明显下降或者设备性能即将发生损坏故障时才可以强行停电,使设备从运行状态中退出来对设备进行检修。这样一来就能够保障继电保护装置一直处于运行状态,防止二次继电保护设备因为定期检修维护导致的一次设备停电,最大程度上提升设备运行效率。

The function of overhaul secondary relay protection state maintenance is to protect the device.At the same time,it can evaluate the operating state of the device,change the mode of traditional periodic maintenance,and carry out state maintenance according to the operating state of the equipment.The performance of the equipment is obviously reduced or the performance of the equipment is about to be improved.In the event of a damage failure,the power can be forcibly interrupted,and the equipment can be taken out of the operating state to repair the equipment.In this way,it is possible to ensure that the relay protection device is always in operation, and prevent the secondary relay protection device from being power-off due to periodic maintenance and repair,thereby maximizing the operation efficiency of the device.
