Five-prevention lock intelligent navigation control system for transformer substation

Abstract

The invention relates to a five-prevention lock intelligent navigation control system for a transformer substation. The five-prevention lock intelligent navigation control system comprises a central control room, a control module set of the central control room, the transformer substation, a control module set of the transformer substation and five-prevention locks. The control module set in the central control room transmits and receives signals of the control module set of the transformer substation and navigates and prompts all switch cabinets in the transformer substation to avoid misoperation. The system uses the design concept of automobile navigation for reference, on the basis of considering defects existing in the on-site use process of the transformer substation, actual on-site arrangement conditions of primary equipment and secondary equipment are combined, the navigation function is added, operation and path indication is provided for operators at work, and voice indication and visual indication are given when errors occur to prevent electric misoperation.

Description

technical field [0001] The invention belongs to the field of electric power technology, and relates to a technology for preventing misoperation of a substation, in particular to a substation five-proof lock intelligent navigation control system. Background technique [0002] In the substation of the power system, the five-proof locking system is currently the most widely used and most practical measure to prevent electrical misoperation. But present computer key has following defect in use process: [0003] 1. With the advancement of the construction of unattended substations and substation operation and maintenance stations, coupled with the commissioning of new substations, multiple operating personnel who were on duty in a fixed substation need to be there, and they are not familiar with the implementation of switching in the substation. Gate operation, the same problem is more prominent for new employees, which will directly lead to a lot of time wasted when looking for...

AI Technical Summary

Problems solved by technology

[0003] 1. With the advancement of the construction of unattended substations and substation operation and maintenance stations, coupled with the commissioning of new substations, multiple operating personnel who were originally on duty in a fixed substation need to be present. They are not familiar with the implementation of switching in the substation. Gate operation, the same problem is more prominent for new employees, which will directly lead to a lot of time wasted when looking for operating equipment, reducing work efficiency

[0004] 2. When the five-proof lock is placed in the wrong position, if the operator does not carefully check whether the five-proof lock corresponds to the locked device after opening the lock, electrical misoperation accidents may occur, and the consequences will be disastrous

[0005] 3. Unpredictable possible dangers and precautions during operation

[0006] Through the search, no relevant published patent documents were found
