Motivation U or V coil connects.Compared with prior art, the diode for rectification being connect with turn-out track electric motor is eliminated.
The DC power supplies such as independent silicon rectifier are set in outdoor terminals cable box, AC power are converted to independent straight
Galvanic electricity source.
By DC power supply and indicate that relay is arranged in the both sides of the outside cable of possible swinging cross.For example, straight as shown in Figure 2
Galvanic electricity source indicates relay FBJ in the both sides outside cable X7-X9 with normal indication relay DBJ/ antipositions, it is therefore prevented that outdoor is mixed
Line failure.Because if DC power supply and indicating relay setting in homonymy, when swinging cross occurs for outside cable, DBJ/FBJ indicate after
Electric appliance meeting mistake picks up.
The goat contact for going in line and loop line to access same type of relay is indicated in DBJ/FBJ.For example, as schemed
Shown in 2, in indication circuit, DBJ indicates connection goat the contact 33-34 and 15-16 in line that go of relay, is connected in loop line
Goat contact 35-36；FBJ indicates connection goat the contact 23-24 and 45-46 in line that go of relay, connects and turns in loop line
Rut machine contact 25-26.This arrangement reduce hazardous side failure rates.Because if loop line is not connected to goat contact, going line electric
When swinging cross occurs for cable, DBJ indicates that relay meeting mistake picks up.
Only there are two types of situations for goat action：It positions and is converted to antiposition conversion and antiposition to positioning, indicate that relay is exactly
The result of above-mentioned two situations conversion in place is embodied, so in the DBJ/FBJ of indication circuit indicates relay circuit simultaneously
The inspection condition of this two kinds of situations is accessed, that is, access locating rotation relay DZJ and antiposition rotate relay FZJ, specifically
