The Design And Research Of Gdjy Rail Insulation Online Tester

Most of the crane faults of electricity system occur by rail and track circuit that is failure. And most of the orbital circuit faults are caused by insulation breakage. Because,the damaged of rail insulations are quite complex. And search the problem is very difficult. So,the detection of the track circuit insulation fault is the problems need to be solved by therailway electricity maintenance.In theory,design a good online testing of rail insulation performance is this topic purpose.The technical ideas paper theoretically is the initiative to be point (insulation place) input a small range.But more often than rail signal frequency band signal.Then the signal to receive back spectral analysis.Use filters filter rail signal and all kinds of jamming signal.Then use the spectrum analysis method can effectively says insulation resistance signal.And according to the signal components are calculated and displayed by the measuring point insulation resistance value. So and judge the performance of insulation section.The main contents include paper is track circuit and the basic theory of insulation section,rail insulation formation and characteristics,track circuit insulation equivalent second segment network theory analysis,track circuit principle,safety orientation in the application of the principle of railway design. hardware and software flow principle diagram design of insulation tester. Identify ways is good or not of Insulation quarter performance.And each part gives detailed discussion.The next,this paper expounds the product commissioning theory,hardware debugging,software debugging commissioning and assembly process,and normal regular project main technical testing methods.It is concluded that design this tester method is feasible, and gives a detailed conclusion. In the actual rail insulation testing, this instrument is the online measurement orbit insulation festival can be performance of the instrument.
