| 摘 要： | 电气主要设备保护的原有理论基础较基佗保护薄弱，而且目前正普遍推广微机保护。针对主设备保护几个有争议的问题，如定子绕组故障的主保护，变压器差动保护，大型发电机变压器的接地故障保护等，提出了明确的观点，同时呼吁进一步加强主设备保护的应用研究。

| Abstract: | The original theoretic base of electric main equipment is weaker than other protections, moreover,widespread popularization of microcomputer protection lies ahead of us.Aimed at the contentious problems of main wquipment protection, such as main protection of stator winding trouble, differential protection for transformer, earth fault protection for big generator and transformer etc, the author proposes the clear viewpoints and appeals for greater effort into the application on main equipment protection. |
