Intelligent high voltage alternating-current metal enclosed switchgear and control device

Abstract

The invention discloses an intelligent high voltage alternating-current metal enclosed switchgear and a control device. The intelligent high voltage alternating-current metal enclosed switchgear comprises a metal enclosed frame, and the inner portion of the frame is divided into an instrument compartment, a breaker compartment, an incoming line compartment and an outgoing line compartment through metal devices; a proximitor and a compartment measurement and control instrument are arranged in the instrument compartment; a breaker body is arranged in the breaker compartment, a body controller is installed in the breaker body in an embedded mode, and a chassis truck is arranged at the bottom of the breaker body; the body controller is connected with the proximitor through a serial communication channel, the proximitor is connected with the compartment measurement and control instrument through a serial communication channel, and the two ends of each serial communication channel are provided with electric isolation circuits; the breaker compartment and the outgoing line compartment are respectively provided with a heater, a fan and a temperature sensor which are connected with the compartment measurement and control instrument and used for regulating and controlling compartment environment; at least one compartment is provided with a door state sensor for realizing logic control over compartment doors and a door lock. The intelligent high voltage alternating-current metal enclosed switchgear and the control device are excellent in performance, concise, simple in set forming, reliable to run, convenient to maintain and high in performance cost ratio.
