Embodiment

Below in conjunction with Figure of description the utility model is described in detail.

Switch control circuit is made up of turnout start circuit and switch indication route two parts.Start-up circuit is the circuit of action electric point machine, conversion track switch, and indication circuit is the circuit of reflection switch location.The start-up circuit of usual track switch adopts the step control mode, at first checks the interlocking condition by the first switch starting relay 1DQJ, is controlled the conversion direction of motor then by the second switch starting relay 2DQJ; At last by direct current motor conversion track switch.X1 line and X5 line are that track switch is to positioning starting circuit industrial siding, X2 line and X6 line are that track switch is to antiposition start-up circuit industrial siding, the X4 line is a track switch to deciding the bridging line that antiposition starts, and X1, the X2 track switch of holding concurrently forwards the expression line of relevant position to, and X3 is the expression bridging line that track switch forwards the relevant position to.

When switch was located rotation left, its host-initiated circuit was: DZ220---reometer---QJ _1-2---QJ111-112---ZK15-16 (X1)---main frame stator winding 1-2---main rotor winding 3-4---X4---QJ141-143---ZK7-8---DF220.Secondary machine circuit is: DZ220---reometer---QJ _1-2---QJ111-112---ZK17-18 (X5)---secondary machine stator winding 1-2---secondary machine rotor winding 3-4---X4---QJ141-143---ZK7-8---DF220.Automatically cut off the automatic lid actuator of goat itself after the major-minor machine all forwards the position to, make the motor stall, QJ falls, and shows the L lamp surely and lights.Its circuit is JZ220------QJ113-111---ZK15-16---X1---host node---secondary machine contact---X3---QJ131-133---RD---JF220 that shows diode lights surely.

Usual recovering state to 0.

Its principle of antiposition is with the location to the right when switch, and just start-up circuit is changed into main frame through X2, stator winding 3-4 (making the motor counter-rotating), and secondary machine is through X6, stator winding 3-4 (making the motor counter-rotating).Indication circuit changes X2 into and goes, and X3 returns.

The user mode explanation:

1, ZK (the three-position type switch is handled the track switch effect of 2DQJ relay of holding concurrently)

(1) 1-2,3-4,5-6 connects (this contact is not used) 0 the time in the middle of

7-8,9-10,15-16,17-18 connect when (2) locating left

(3) 7-8,9-10,11-12,13-14 connect during antiposition to the right

2, the QJ relay adopts JWJXC-H125/0.44 type, changes 125 Ω line looks into 850 Ω, and outer cover and socket cancellation are to reduce volume.

3, DC ammeter is for surveying frictional working current with 0 ~ 5A.

4, commutation diode Z1 ~ Z4 2CZ-20A/600V.Z5-Z6 because of it is a short-time current, does not need radiation fin with 2CZ-2A/500V.
