摘要
在继电保护过程中,电气设备的内置电池电源往往无法保证对电气元件进行实时监控,而现有的技术手段中带电检测和在线监测空心电抗器也因为电源技术的不达标未能做到实时监控。因此,提出一种新型自取能装置,利用空心电抗器自身的结构特点,为空心电抗器的感温元件提供持续直流电,使其达到实时监控,并且在故障发生前进行一种预视保护,为空心电抗器的安全运行提供了一种保障。
In the process of relay protection,the built-in battery power supply of electrical equipment is often unable to ensure real-time monitoring of electrical components,while the existing technical means of live detection and online monitoring of hollow reactor cannot achieve real-time monitoring because of the substandard power supply technology.Therefore,a new type of self-extracting device was put forward in this paper,which provided continuous direct current for the temperature sensing elements of the core reactor by making use of its own structural characteristics,so as to achieve real-time monitoring,and provided a previewing protection before the failure,providing a guarantee for the safe operation of the core reactor.
