Technical field
The present invention relates to lightning protection field, be specifically related to a kind of transmission line of electricity current state of lightning protection assessment system.
Background technology
Transmission line of electricity is owing to being chronically in natural environment, and mostly passes through wilderness, hills or high mountain, and the probability being struck by lightning is much larger than other power equipment, and therefore transmission line of electricity is the emphasis of lightning protection research.Domestic transmission line of electricity the most usually uses on-the-spot test, test data are processed by manual analysis, its current state of lightning protection is estimated, but because the data of transmission line of electricity lightning protection test are more, the most manually analyze and process not only workload the biggest, and bigger error often occurs, have a strong impact on the assessment to transmission line of electricity current state of lightning protection.
Summary of the invention
The technical problem to be solved in the present invention is: based on data base and computer technology, by computer, transmission line of electricity test data are carried out computational analysis process, thus transmission line of electricity current state of lightning protection is effectively judged, and provide the report of rational current state of lightning protection, it is possible not only to solve the problem that artificial treatment workload data is bigger, and the accuracy of current state of lightning protection research can be improved.
For achieving the above object, the present invention takes techniques below scheme: a kind of transmission line of electricity current state of lightning protection assesses system, it is characterised in that: include data base and software system.Described data base includes lightning protection data message and thunder-strike prevention standard, described lightning protection data message includes insulator information, shaft tower information, wire information, lightning conducter information, spark gap information, circuit common parameter information, the detail parameters information of every base shaft tower, result of calculation information, and described thunder-strike prevention standard includes the transmission line of electricity thunder-strike prevention standard that country is up-to-date;Described software system includes transmission line of electricity lightning protection calculation input module and transmission line of electricity current state of lightning protection report output module; described transmission line of electricity lightning protection calculation module includes that shielding angle calculating, resistance to thunder level calculation and tripping rate with lightning strike calculate, and the report of described transmission line of electricity current state of lightning protection includes earth resistance, shielding angle, resistance to thunder level, tripping rate with lightning strike.
As further illustrating, the above circuit common parameter information includes wire type, wire safety coefficient, lightning conducter model, the safety coefficient of lightning conducter.
As further illustrating, the parameters such as the detail parameters information of the above every base shaft tower includes location type, earth resistance, and shaft tower is numbered, insulator type, shaft tower type.
As further illustrating, the above result of calculation information includes shielding angle, strikes back resistance to thunder level, shielding resistance to thunder level, strikes back trip-out rate, back flash-over rate.
As further illustrating, the above water of resistance to thunder calculates and includes strikeing back resistance to thunder level, shielding resistance to thunder level.
As further illustrating, the above tripping rate with lightning strike calculates and includes strikeing back tripping rate with lightning strike and shielding tripping rate with lightning strike.
The beneficial effects of the present invention is: the present invention is based on database technology, by the computational analysis function powerful by computer, the most successfully solve the problem that artificial treatment lightning protection workload data is big, and improve the accuracy of transmission line of electricity current state of lightning protection research.
