摘　　要：在介绍了三元件失步保护的原理和整定方法后,通过分析和比较各种保护校验方法的优缺点,总结了这些方法不一定能准确校验定值动作边界的原因,同时指出了这些校验方法都无法对透镜内角和灵敏角进行校验,最后提出了透镜内角和灵敏角的校验方法,并以典型值为例说明了该方法。After introducing the principle and setting method of three-component out-of-step protection,the advantages and disadvantages of various calibration methods for protection are analyzed and compared,and the reason why these methods may not be able to accurately verify the boundary of definite action is summarized.Meanwhile,it is pointed out that these calibration methods can not verify the interior angle and the sensitivity angle of the lens.Finally,the calibration method for the interior angle and the sensitivity angle of the lens is put forward and described by taking the typical value as an example.
