变压器有载分接开关常见故障分析

Common Fault and Analysis of Load Tap Changer in Transformer

电力系统飞速发展的同时,人们对电力系统的安全性及稳定性也提出了更高的要求。变压器有载分接开关不仅具备稳定中心电压的作用,而且还能用于协调电网分布,与电气设备运行、供电质量等具有密切的关联。如果变压器有载分接开关出现故障,不仅会对人们的生产、生活造成不良影响,甚至可能危及人身安全。本文围绕变压器有载分接开关常见故障展开分析。

At the same time of the rapid development of the power system, people have put forward higher requirements for the security and stability of the power system. Transformer load tap switch not only has a stable center voltage, but also can be used for the coordination of the electric power distribution, closely related to the operation of the electrical equipment, the quality of power supply, if the OLTC transformer failure, not only to the people's production and life caused by adverse effects, and may even endanger personal safety. This paper analyzes the common faults of the load tap changer of transformer.
