Distributed power transmission and distribution line maintenance operation safety protection digital monitoring system

Abstract

The invention discloses a distributed power transmission and distribution line maintenance operation safety protection digital monitoring system. The system includes a grounding wire monitoring device used for monitoring grounding resistance and grounding geological position of each grounding wire to provide a basis for judging a grounding effect and receiving and executing data and commands issued by a master station; a personnel monitoring device used for monitoring geological position information of maintenance personnel and a maintenance process; the master station which is in communication connection with the grounding wire monitoring device, a line monitoring device and the personnel monitoring device and performs information acquisition, information processing and information publishing on the abovementioned devices; and a client which provides a human-computer interaction interface and is in communication connection with the master station. The distributed power transmission and distribution line maintenance operation safety protection digital monitoring system has the following advantages: power transmission and distribution line electric misoperation is prevented, personal safety and power grid safety are guaranteed, and great convenience is brought to safety management and control of a maintenance site by departments of electric power maintenance, safety supervision, dispatching and the like.

Description

technical field [0001] The invention relates to the field of electric power intelligent detection, in particular to a digital monitoring system for safety protection of distributed power transmission and distribution line maintenance operations. Background technique [0002] For large-scale power transmission and distribution line maintenance operations, the distribution of grounding wire installation and maintenance personnel is characterized by multiple points and wide areas. Many operating ranges exceed 1 kilometer. The staff need to wait for the grounding wires to be installed before they can start the pole climbing operation. After the maintenance work is completed, it is necessary to confirm whether the wiring is normal, whether there are leftover grounding wires, and whether the operators have evacuated, so as to judge whether the conditions for power transmission are met. It will take a lot of time to conduct a tail inspection. Not only is the efficiency low, but it ...

Problems solved by technology

There are many talks about the intelligence of a specific field of the system. At present, it is possible to monitor the "two states" of whether the grounding wire is grounded or not. It can only judge whether the line is installed or missing grounding, but it cannot monitor the grounding resistance. Quantitative and digital online detection cannot further judge whether the grounding effect is good and whether the grounding is effective. Further positioning and digital monitoring of the working status of maintenance workers are less involved. Comprehensive system for safety protection monitoring
