Operation principle
（1）：When not connecting insertion point type LED railway signal lamps（It is unloaded）.H, R both ends power on alternating current 220V when, by
It is unloaded in system（Dotted line frame C is not connected）, J2 line bag no currents pass through, contact KJ2 closure（Connect）It is not operating.
（2）Point type LED railway signal lamps are inserted into when connecting（There is load）When, if system is working properly, J2 lines are surrounded by electricity
Stream passes through, king light（D）Work is lighted, KJ2 is picked up（Disconnect）Secondary lamp does not work（Do not work）.If king light is abnormal, in J2 line bags
No current passes through KJ2 releases（Connect）, secondary lamp lights（Work）And alarm.
During normal work, there is electric current in J2 line bags by the way that lamp circuit can control main lamp current in safe range（It is defeated
Enter voltage 220V positive and negative 10%）
In normal work, if this insertion point type LED railway signal lamp king light illuminators are faulty（Open circuit or short circuit）
When, then fuse B1, B2, B3, B4, B5 moments fuse, king light is turned off the light, and inflow current type relay J2 lines bag electric current is less than at this time
40MA, J2 discharge, and normally closed point KJ2 closures, insertion point type LED railway signal lamp pair lamps are lighted, and are alarmed.
In normal work, if the rectifying block W1 damages in king light part（Short circuit）Then fuse B10 fuses, and cuts off king light point
At this time, J2 discharges the electric current of circuit for lamp.KJ2 contact closures（KJ2 is normally closed point）.Secondary lamp is lighted, and is alarmed.
If king light breaks down, secondary lamp also breaks down at this time, then protects circuit start work,（I.e. fuse B1, B2,
B3, B4, B5, B6, B7, B8, B9 fuse）This insertion point type LED railway signal lamps（Dotted line frame C）External relay J1, J2 are at the same time
Discharge and alarm.
If element W1, W2 are damaged in succession in the lamp circuit of king light and secondary lamp, fuse B10, B11 also fuse in succession,
It is approximately zero to flow through electric current in relay J1, J2 line bag at this time, the release of J1, J2 contact.It is another with itself after relay J2 releases
Group contacting alarm circuit, alarm（On railway it is former intrinsic not on the diagram) be installed on the current relay J1 of monitoring room
（Dotted line frame A）Also discharge, alerted with another alarm circuit of itself contacting, and perform independently of all outside this line map 4
