摘要
对变压器铁芯接地装置运行原理进行了详细阐述,通过对比正常运行的一点接地和故障状态下的多点接地,论述了铁芯接地系统限流装置的原理和作用,并分析在一点接地和多点接地情况下的应用效果,为变压器是否选择铁芯接地装置提供了简易参考依据。合理运用变压器铁芯接地电流限流装置,有助于及时发现故障,并及时限制接地电流,保障变压器的安全稳定运行。
In this paper,the operation principle of transformer core grounding device is described in detail.The principle and function of current limiting device for iron core grounding system are discussed by comparing one point grounding in normal operation with multi-point grounding in fault state.The application effect under one point grounding and multi-point grounding is analyzed,which provides a simple reference basis for transformer to choose iron core grounding device.Reasonable application of transformer core grounding current limiting device can help to find faults in time,limit grounding current in time and ensure safe and stable operation of transformer.
