The utility model relates to the technical field of power systems, in particular to a one-key
sequential control switch cabinet, which is provided with a cabinet body and a
control system arranged on the cabinet body, the
control system comprises a controller, a
circuit breaker operating mechanism and a three-position operating mechanism, the controller is a
programmable logic controller and is provided with a one-key
sequential control logic program, and the three-position operating mechanism is provided with a three-position operating mechanism. The controller is electrically connected with the
circuit breaker operating mechanism and the three-
station operating mechanism respectively, so that the controller controls the
circuit breaker operating mechanism and the three-
station operating mechanism to execute switching-on and switching-off operations through a one-key
sequential control logic program, and an
interlocking device is further arranged between the circuit breaker operating mechanism and the three-
station operating mechanism. Therefore, the two are interlocked in the operation process. Compared with the prior art, by adopting the automatic and intelligent technical means, the problems in the prior art are effectively solved, the safety, the reliability and the working efficiency of an
electric power system are improved, the operation and maintenance cost is reduced, and remarkable technical progress and practical application value are achieved.
