Stand；After electric locomotive enters entrucking position and comes to a complete stop, successively cut-out ocs isolating switch 2 and rail backflow disconnecting switch 3, with
Avoid the electricity consumptions such as headstock to produce sparking and cause accident.While disconnecting track return disconnecting switch 3 and ocs isolating switch 2
To flow back contact net ground connection in rail and station, in case the residual static electricity sparking of backflow rail and contact net causes accident.Rail
Backflow disconnecting switch 3 in road first closes when switching on and off and connecting with interlock strict guarantee with ocs isolating switch 2
Track return disconnecting switch 3, then closes ocs isolating switch 2, first disconnects ocs isolating switch 2, then break during disjunction
Open track return disconnecting switch 3.Survey quick-fried equipment 5 when gas can automatic blocking track to return when monitoring that fuel gas is exceeded simultaneously
Stream disconnecting switch 3 and the closing device of ocs isolating switch 2, make track return disconnecting switch 3 and ocs isolating switch 2 not
Can close a floodgate, intelligent alarm equipment red eye is lighted, flashed simultaneously, and sends strong chimes of doom, forbids that electric locomotive enters
Stand.
This railway terminal intelligent electromagnetic guard system is arranged on the detailed operation explanation in railway terminal：
Goods line in normal condition, when depots and goods yard do not carry out operation, ocs isolating switch 2 and track return every
Leave pass 3 all to open, Insulation Live Testing equipment 8, backflow testing equipment 4, ipping coil primary means 7, gas survey quick-fried equipment 5 simultaneously
Real-time monitoring is carried out to whole loading station, and detection data is fed back to intelligent controlling device 6, when intelligent controlling device 6 detects
During to 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 is first judged that whole loading station is
No can carry out operation, when detection can when, intelligent control device 6 will first closed orbit backflow disconnecting switch 3 be then in order
Closure ocs isolating switch 2, guiding electric locomotive enters；Otherwise intelligent alarm equipment will send warning, show problem points.
When electric locomotive is completely into depot, intelligent controlling device 6 will be switched off that 2 passes kept apart by contact net and track returns
Stream disconnecting switch 3 simultaneously sends and can operation indicate；The quick-fried equipment of operation seasonal epidemic pathogens body examination 5 carries out real-time detection, when handling operation completes simultaneously
And the concentration of explosive mixed gas is when being less than LEL 20%, it is right that intelligent controlling device 6 first close the rail disconnecting switch 3 that flows back
Close ocs isolating switch 2 afterwards, by after tank car and lorry pull-out goods line, intelligent controlling device 6 presses reverse-order again for electric locomotive
Open switch (first disconnect ocs isolating switch 2 and be then turned off rail backflow disconnecting switch 3), recover normal condition.
