针对变压器差动保护和重瓦斯保护无法灵敏和快速判别变压器轻微匝间短路故障的问题,研究了变压器正常运行与不同匝间短路情况下的漏磁分布特性。首先,推导了变压器绕组在空间中的磁密分布公式,分析了变压器正常运行时的轴向漏磁分布对称性规律;然后,搭建了“场-路”耦合110 kV三相变压器三维模型进行仿真验证,分析变压器在正常运行、不同故障绕组、不同匝间短路位置下的漏磁分布规律。最后,基于理论分析和仿真验证,提出了变压器内部漏磁传感器的布置方案,为基于漏磁信息的匝间短路故障辨识提供依据。
To solve the problem that transformer differential protection and Buchholz protection can not sensitively and quickly distinguish slight turn-to-turn short-circuit fault of transformers
the leakage flux characteristics of the transformer under normal operation and different turn-to-turn short-circuit conditions are studied. Firstly
the magnetic density spatial distribution formula of the transformer winding are derived
and the symmetry of axial leakage flux distribution during normal operation of the transformer is analyzed. Then
a three-dimensional “field-circuit” coupled 110 kV three-phase transformer model is built for simulation verification
and the leakage flux distribution rule of the transformer under normal operation
different fault windings
and different turn-to-turn short-circuit positions is analyzed. Finally
based on theoretical analysis and simulation verification
the layout scheme of leakage flux sensors in the transformer is proposed
which provides a basis for turn-to-turn short-circuit fault identification based on leakage flux information.
