直流长期带电试验方法、系统以及电极加载方法、装置
摘要：
本发明涉及一种直流长期带电试验方法、系统以及电极加载方法、装置，直流条件下，环氧类电气绝缘材料的耐久性目前还没有相关标准、相应的试验方法和评价体系，因此，对电气绝缘材料在直流电压下的电寿命评价没有一个明确的途径，本发明是一种适用于环氧类电气绝缘材料的直流长期带电试验及电寿命评价方法，方法规定了材料试样尺寸，加载电压、加载时间，中间参数测量方式、外推曲线绘制、寿命判定依据等，为电气绝缘材料在直流电压下的耐久性和电寿命评定提供了重要依据，从而为电力设备整体寿命评定提供技术支撑。
摘要（英）：

The invention relates to a DC long-term live-line test method, a system, an electrode loading method and a device. Under the DC condition, no relevant standards, no corresponding test method and no evaluation system for endurance of epoxy type electrical insulating materials exist in the prior art, and electric life evaluation of the electrical insulating materials under the DC voltage condition has no clear way. The method is a DC long-term live-line test and electric life evaluation method suitable for the epoxy type electrical insulating materials. According to the method, material sample dimension, loading voltage, loading time, intermediate parameter measurement mode, extrapolation curve drafting, life determination bases are prescribed, important bases are provided for endurance and electric life evaluation of the electrical insulating materials under the DC voltage condition, and thereby technical support is provided for integral life evaluation of electric power equipment.
