Detailed description of the invention
Automatic to electric railway ground based on solid converting switch of the present utility model in conjunction with accompanying drawing
Neutral-section passing system structure is illustrated.
Electric railway ground automatic passing over of neutral section system based on solid converting switch of the present utility model
System, this system is arranged in contact net CL electricity split-phase neutral area NZ, and it is neutral that electric locomotive is positioned at electricity split-phase
Time between district's contact net and rail, obtaining electric energy from contact net neutral area, this system includes that solid-state switching is opened
Closing, overvoltage inhibiting apparatus RC, solid converting switch loop protection switchs, locomotive position detection device,
Described locomotive position detection device be arranged on rail, overvoltage inhibiting apparatus be located at neutral area contact net with
Between rail, solid converting switch and solid converting switch loop protection switch connection contact net neutral area and
Adjacent both sides contact net；By conducting solid converting switch, electricity split-phase neutral area NZ in contact net CL is begun
Ensure charged eventually, make electric locomotive all the time with voltage AB phase when contact net passes through.
Described solid converting switch include the first electronic power switch F1, the second electronic power switch F2,
3rd protection switch K3, the 4th protection switch K4, solid converting switch loop protection switch includes first
Protection switch K1 and second protection switch K2, described first electronic power switch F1 and the 3rd protection is opened
Pass K3 is connected in parallel and is connected in parallel composition admittedly with the second electronic power switch F2 and the 4th protection switch K4
State switching switch, in order to enable solid converting switch out of service, at solid converting switch two ends respectively
