Operation principle
(1): do not connect when inserting point type LED railway signal lamp (zero load).H, R two ends switch on power alternating current 220V time, due to system zero load (not connecting dotted line frame C), J2 line bag no current passes through, and contact KJ2 closed (connection) is not operating.
(2) when connecting insertion point type LED railway signal lamp (having load), if system works is normal, J2 line is surrounded by electric current to be passed through, and work lighted by king light (D), and KJ2 picks up (disconnection), and secondary lamp does not work (not working).If king light is abnormal, in J2 line bag, no current passes through, and KJ2 discharges (connection), and secondary lamp is lighted (work) and reported to the police.
During normal work, have electric current to pass through in J2 line bag, main lamp current can be controlled in safe range (input voltage 220V positive and negative 10%) by lamp circuit
When normally working, if when this insertion point type LED railway signal lamp king light illuminator has fault (open circuit or short circuit), then fuse B1, B2, B3, B4, B5 fuses instantaneously, king light is turned off the light, now inflow current type relay J 2 line bag electric current is less than 40MA, and J2 discharges, and normally closed some KJ2 closes, insert the secondary lamp of point type LED railway signal lamp to light, and report to the police.
In normal work, if the rectifying block W1 in king light part damages (short circuit), fuse B10 fuses, and cuts off the electric current of king light lamp circuit now, and J2 discharges.The KJ2 closing of contact (KJ2 is normally closed point).Secondary lamp is lighted, and reports to the police.
If king light breaks down; now secondary lamp also breaks down; then protection circuit startup work, (i.e. fuse B1, B2, B3, B4, B5, B6, B7, B8, B9 fusing) this insertion point type LED railway signal lamp (dotted line frame C) outside relay J 1, J2 discharge simultaneously and report to the police.
If element W1, W2 damage in succession in the lamp circuit of king light and secondary lamp, then fuse B10, B11 also fuses in succession, now flows through electric current in relay J 1, J2 line bag and is approximately zero, J1, the release of J2 contact.After relay J 2 discharges, another group contacting alarm circuit with self, alarm (on railway former intrinsic not on figure) is arranged on the current relay J1(dotted line frame A of Control Room) also discharge, with another alarm circuit alarm of self contacting, and perform independent of all security procedures outside this line map 4.
