The utility model provides a switching operation notice board with install and remove real -time prompt facility of earth connection, belongs to high -pressure power transmission and distribution technical field, characterized by: sensitive pressure sensor links to each other with the input of controller, and the output of controller links to each other with several to tens of red lights and audible -visual annunciator, concatenates in the output return circuit of controller after the red light is parallelly connected. The beneficial effects are that: the problem of in the past whole operation projects such as need finish could the registration of beginning earth connection, cause interval time long is solved. Earth connection management has simultaneously realized the intellectuality, has solved and has leaned on artifical inspection earth connection means original in the past, and the problem of inefficiency has improved work efficiency and reliability. In addition, change the working method that relied on guardian and operating personnel inspection in the past alone, confirmed the earth connection use, realized that central control room operation on duty personnel on duty need not look over to the scene in person, can understand, grasp the earth connection and use, guaranteed the correct safe handling of earth connection.
