摘要
随着时代的进步和居民生活水平的提高,居民生产、生活用电需求增长迅速,对配电网供电能力提出了更高要求。配电变压器重、过载问题时有发生,究其原因,除了用电负荷升高这一主要原因外,三相不平衡、采集系统数据异常等原因也不可忽视。针对不同情况,应首先分析造成配变重、过载问题的主要原因,再据此提出针对性解决方案,既要达到治理目标,又要降低治理成本。
With the progress of the times and the improvement of the living standard of the residents, the demand for the production and living electricity of the residents is growing rapidly, and the power supply capacity of the distribution network is higher. In addition to the main reason of the increase of power load, the reasons for the problem of weight and overload of distribution transformers are not negligible. In view of different situations, the main reasons for the problem of weight distribution and overload should be analyzed first, and then the targeted solutions should be put forward, so as to achieve the goal of governance and reduce the cost of governance.
