摘　　要：为提高电气设备保护动作的灵敏性和可靠性,在保护配置中应用复压闭锁元件是风电场保护配置的常用方式。但是,在实际使用中,因为缺少对复压闭锁元件的有效校验,导致保护装置存在一定的安全隐患。针对此问题,研究了复压闭锁元件在风电场中的应用,重点分析了复压闭锁元件的校验方法。In order to improve the sensitivity and reliability of electrical equipment protection,it is a common way of wind farm protection configuration to apply multi-voltage locking element in protection configuration.However,in the actual use process,there is a lack of effective verification of the re-pressure locking element,which leads to certain potential safety hazards of the protection device.Based on this,the research first introduces the application of multipressure locking element in wind farm,and then focuses on the analysis of the verification method of multi-pressure locking element.
