Abstract

The most common causes of malfunctions and types of damage to traction substations power transformers are presented and classified, the influence of the climatic conditions of the region of operation on the reliability of the power transformer insulation is shown. The results of the analysis of the damageability of traction substations' power oil transformers with types of damage to the insulation system on the example of a Russia's railroad. The classification of climatic factors affecting the reliability indicators of isolation is proposed, a model of climatic factors influence on the reliability parameters of the transformer is developed and presented in the form of a generalized integral indicator estimated by the climatic impact score. The classification of climatic factors affects the transformer reliability parameters and allows us to outline and develop a strict technology for monitoring the status of the main parameters that characterize the wear level of the transformers and their readiness to work in the future.

用“技术刚度”指标评价气候因素对电力变压器可靠性的影响

介绍了牵引变电站电力变压器最常见的故障原因和损坏类型，并对其进行了分类，说明了运行区域的气候条件对电力变压器绝缘可靠性的影响。以俄罗斯某铁路为例，分析了牵引变电站电力油变压器绝缘系统损坏类型的易损性。提出了影响隔震可靠性指标的气候因素的分类，建立了气候因素对变压器可靠性参数的影响模型，并以气候影响分数估计的广义积分指标的形式给出了模型。气候因素的分类影响变压器可靠性参数，使我们能够概述和开发一种严格的技术，用于监测表征变压器磨损水平及其未来工作准备的主要参数的状态。
