摘要
作为系统运行的主设备,变压器的安全、稳定运行至关重要。而变压器的温度监测是衡量变压器实时运行工况、确定其安全运行的重要手段,也是实现综合自动化变电站无人值班的重要条件之一,因而其重要性不言而喻。本文简要介绍了变压器远方测温系统,并针对远距离测温中出现的数据不稳、接线电阻误差、干扰等问题及其解决办法进行了探讨。
As the primary facility in the power system, it is very important that trasformer runs safely and steadily.The monitoring and measurement of transformer＇s temperature are very important means to judge the transformer＇s nmning situation in real-time and ascertain if it runs safely and make the nobody on duty working mode in the synthetic and automatic transformer substation comes true. This paper introduced the system of remote temperature measurement and discussed data unsteadiness, error of line-resistance, and disturbance etc.
