单相接地引起的10kV电压互感器故障探讨

Fault of 10 kV Voltage Transformer Caused by Single-phase Grounding

随着科学技术的进步,各种先进的技术和电气设备广泛应用在电力系统中,极大地提高了电网的自动化水平和智能化水平。电压互感器具有绝缘性能好、价格比较低、耐压水平高等优点,因此在电网中广泛应用。然而电压互感器在运行过程中受到自身结构缺陷、外部因素的影响很容易出现故障。本文主要分析了由于单相接地引起的10kV电压互感器故障,并对故障发生的原因进行探索,采取必要的措施以提高变电站运行效率,确保电力系统安全、稳定运行。

with the progress of science and technology, all kinds of advanced technology and electrical equipment are widely applied in power system, which greatly improves the automation level and intelligence level of power grid. Voltage transformer has many advantages, such as good insulation, low price and high pressure level, so it is widely used in power grid. However, the voltage transformer is easily broken down by its own structural defects and external factors during the operation. This paper mainly analyzes the 10 kV voltage transformer fault caused by single-phase grounding, explores the causes of the failure, and takes the necessary measures to improve the operation efficiency of the substation, and ensure the safe and stable operation of the power system.
