Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, in the embodiment of the present invention, a kind of railway terminal intelligent electromagnetic protective system, at least comprises rail insulation assembly 1, ocs isolating switch 2, track return disconnector 3, backflow check implement 4, gas surveys quick-fried equipment 5, intelligent controlling device 6, ipping coil primary means 7 and Insulation Live Testing equipment 8; Described rail insulation assembly 1 is made up of rail and insulating part mounted thereto, and rail is connected with grounding lattice; Described ocs isolating switch 2 is connected with contact line conducting wire; Described backflow check implement 4 one end connects rail, its another end is connected with track return disconnector 3; Described track return disconnector 3 connects rail; Described intelligent controlling device 6, ipping coil primary means 7 and Insulation Live Testing equipment 8 are arranged in handling station, and described gas is surveyed quick-fried equipment 5 and is arranged in handling station and outside station and handling station entrance-exit place.Described gas surveys quick-fried equipment 5 and Insulation Live Testing equipment 8 is arranged on the both sides of track inside and outside handling station and is provided with multiple, and described backflow check implement 4 is arranged on track both sides, and described intelligent controlling device 6 arranges intelligent alarm equipment.Pipeline between operating area in railway terminal to storage area installs insulated flange additional.
The principle of work of a kind of railway terminal intelligent electromagnetic of the present invention protective system is:
This railway terminal intelligent electromagnetic protective system, for the loading station of the inflammable explosive articles such as oil depot, when electric locomotive enters the station, priority closed orbit backflow disconnector 3 and ocs isolating switch 2, make electric locomotive obtain electric energy and enough enter loading station; Enter entrucking position when electric locomotive and after coming to a complete stop, successively cut off ocs isolating switch 2 and rail backflow disconnector 3, produce sparking to avoid the electricity consumptions such as headstock and cause accident.To reflux while disconnection track return disconnector 3 and ocs isolating switch 2 contact system ground connection in rail and station, in case the residual static electricity of backflow rail and contact system is struck sparks cause accident.Track return disconnector 3 and switching on and off of ocs isolating switch 2 have first closed orbit backflow disconnector 3 when interlock strict guarantee is connected, then closed ocs isolating switch 2, first disconnect ocs isolating switch 2 during disjunction, then disconnect track return disconnector 3.Survey quick-fried equipment 5 when gas can the closing device of coupler lock track return disconnector 3 and ocs isolating switch 2 when monitoring fire gases and exceeding standard simultaneously, track return disconnector 3 and ocs isolating switch 2 can not be closed a floodgate, intelligent alarm equipment red eye is lighted, is glimmered simultaneously, and send strong chimes of doom, forbid that electric locomotive enters the station.
The detailed operation that this railway terminal intelligent electromagnetic protective system is arranged in railway terminal illustrates:
Goods line is when normal condition, when operation is not carried out in depots and goods yard, ocs isolating switch 2 and track return disconnector 3 are all opened, the equipment of Insulation Live Testing simultaneously 8, backflow check implement 4, ipping coil primary means 7, gas are surveyed quick-fried equipment 5 and are carried out Real-Time Monitoring to whole loading station, and data feedback will be detected to intelligent controlling device 6, when intelligent controlling device 6 detects problem, intelligent alarm equipment, by automatic alarm, points out problem points.
When goods line enters car, before needing operation, according to monitoring data, intelligent controlling device 6 first will judge whether whole loading station can carry out operation, when detect can time, then intelligent control device 6 will close ocs isolating switch 2 by first closed orbit backflow disconnector 3 in order, guide electric locomotive to enter; Otherwise intelligent alarm equipment will send warning, demonstrate problem points.
When electric locomotive enters loading-unload station completely, disconnection contact system is kept apart 2 passes and track return disconnector 3 and sent by intelligent controlling device 6 can operation instruction; During operation, gas is surveyed quick-fried equipment 5 and is detected in real time, when loading and unloading operation complete and the concentration of explosive miscellaneous gas lower than Lower Explosive Limit 20% time, intelligent controlling device 6 is closed rail backflow disconnector 3 then closed ocs isolating switch 2 first, electric locomotive is by after tank car and lorry pull-out goods line, intelligent controlling device 6 opens switch (namely first disconnecting ocs isolating switch 2 then disconnection rails backflow disconnector 3) by reverse-order again, recovers normal condition.
