摘要
针对特高压变电站继电保护常见故障,如继电保护装置绝缘以及干扰、互感器二次回路故障问题等进行分析。提出了参照法、替换法等方法。最终能够切实维护好变电站继电保护装置稳定运行。从中可以看出,要想确保特高压变电站继电保护更具可靠运行状态,就必须全面应对其故障问题。
Analyze common faults of UHV substation relay protection,such as insulation and interference of relay protection devices,and faults of transformer secondary circuit.The reference method,substitution method and other methods are proposed.In the end,the stable operation of the relay protection device of the substation can be effectively maintained.It can be seen from this that,in order to ensure a more reliable operation of UHV substation relay protection,this requires a comprehensive response to its failure problem.
