Main wiring display device based on branch circuit in-service and out-of-service states in intelligent substation

Abstract

The invention discloses a main wiring display device based on branch circuit in-service and out-of-service states in an intelligent substation. The structure of the main wiring display device comprises an external lead wire, an in-service and out-of-service device and an outer shell, wherein the external lead wire is electrically connected with the in-service and out-of-service device, and the in-service and out-of-service device is installed in the outer shell. Under the combined action of a first mechanical transmission mechanism, a manual device, a driving mechanism, an electric energy device, an electric energy control mechanism, a second mechanical transmission mechanism and a third mechanical transmission mechanism, the main wiring display device can realize the effect of initiatingelectric signal transmission between branch circuits and a main connecting line when the branch circuits are in use, indicates that the branch circuit does not come into service when a controller of the main connecting line cannot receive an electric signal of one branch circuit, is convenient to intuitively determine which are in-service operating branch circuits and which are out-of-service disabled branch circuits, and avoids the risk of misidentifying the disabled branch circuits as the operating branch circuits.

Description

technical field [0001] The invention relates to the field of intelligent substations, in particular to a main wiring display device based on the switch-in and withdrawal status of branches in the intelligent substation. Background technique [0002] The main wiring forms of the primary system in the substation are various, the number of access branches is different, and there are various operation modes such as branch switch switching, bus switching, and bus interconnection. [0003] In the traditional main wiring display mode, the busbar protection device is displayed according to the largest branch circuit that can be supported. There are many display pages, and the data display content is limited and crowded. . [0004] The smart substation in the prior art cannot visually judge from the main wiring diagram of the device LCD which is the operating branch that is put into use and which is the deactivated branch that is not put into use, and there is a risk of misidentifyi...
