Description

technical field

[0001] The invention relates to a safety protection device for power system operation. Background technique

[0002] The importance of safe production to the power system is self-evident, and the "five defenses" are extremely critical to ensure the safety of the power grid. The so-called "five defenses" refer to: 1. Prevent wrong opening and closing of the circuit breaker; 2. Prevent pulling and closing the disconnector with load; stray into live interval. For a long time, the "five defenses" have basically been guaranteed by human subjective factors such as the work experience and sense of responsibility of the operators in the power system, and lack of corresponding technical equipment means. From the objective conditions, the types of equipment used in the power system There are many, complex operation items, wide distribution of work locations, and different working conditions, which lead to human error operations, frequent occurrence of vicious acciden...
