Description
Technical Field
The utility model relates to the technical field of rail transit, in particular to a five-wire system turnout switch machine simulation circuit and a five-wire system turnout switch machine simulation system.
Background
At present, most of switches of subways adopt three-phase alternating-current switch machines, and switch simulation conditions are manufactured according to the working principle of the three-phase alternating-current switch machines. Because the switch machine equipment can not be installed outdoors in the earlier stage, the positioning and the reverse state of the turnout need to be simulated when the interlocking test is carried out indoors.
The existing switch control circuit, i.e. the drive part, is analyzed. Generally, a three-phase alternating current point switch adopts a five-wire control circuit, which indicates that the relay adopts a polarized relay, and the relay can normally work only if a positive power supply and a negative power supply are correct. According to the working conditions of the positioning relay and the reverse relay, the switch in the switch combination indicates that the transformer alternating current 220v power supply must be supplied, and after the microcomputer interlocking system sends a driving command, the operation relay YCJ, the positioning operation relay DCJ and the reverse operation relay FCJ are allowed to act. After the corresponding action of the starting relays 1DQJ and 2DQJ is finished, the turnout indicates that the transformer is powered on, an outdoor indicating circuit loop is switched on, and the corresponding positioning and reverse relay is sucked up to finish the outdoor indicating function of the turnout.
According to the above analysis, the pick-up of the positioning and inverting relay is performed by the switch indicating transformer output power through a circuit formed by a diode connected in series with 30052/75W in the outdoor switch machine. Therefore, before the turnout simulation conditions are made, the output end of the turnout indication transformer in the indoor turnout combination is changed from the original 110V to 60V for output, and the original state is recovered after the outdoor conditions are met. During simulation, only the turnout output ends 1#, 4# and 5# at the indoor distribution board are required to be bridged together, and then 2 diodes with opposite polarities are respectively connected between 1# and 2# and between 1# and 3# to finish the manufacture of turnout simulation conditions.
The existing turnout simulation conditions can only simulate the positioning representation and the reverse representation of a five-wire switch machine. In the turnout control circuit, only the positioning indication relay DBJ and the reverse position indication relay FBJ of the turnout are controlled, and the purpose can be achieved without sending a normal alternating current 380V power supply, so that the simulation condition for manufacturing the turnout control circuit is relatively simple.
