基于“温度-电流”曲线的10 kV开关柜动态运维策略研究及应用

Research and Application of Dynamic Operation and Maintenance Strategy of 10 kV Switchgear Based on Temperature-Current Curve

以10kV大电流开关柜为研究对象,建立了一种基于设备健康度及历史“温度-电流”曲线的10kV开关柜预警模型,并根据模型提出了运行限值及预警值的运维策略。通过在东莞供电局6个供电分局的应用,分析了模型及运维策略的有效性。

In this paper, a 10 kV high-current switchgear is used as the research object, and a 10 kV switchgear early warning model based on the equipment health and historical temperature-current curve is established. The operation and maintenance strategy of operation limit and warning value is proposed according to the model. Through the application of six power supply bureaus in Dongguan Power Supply Bureau, the effectiveness of the model and operation and maintenance strategy is analyzed.
