This product selection safety relays for optimum design, in view of the type turn point machine characteristics, realized speed the construction of the rail circuit training, joint the actual, the application of the flexible, high reliability, is the rail transit kind professional training for electrical device of choice.

This product according to the field application, combined with the practical teaching characteristics, the cabinet to structure, three parts of control circuit integration to a cabinet put oneself in another's position in realize speed rail circuit all function at the same time, still constitute the electrical concentrated in a complete electrical combination circuit, can let students to rail control circuit have a whole understanding, grasps the rail control electric circuit principle of work, skilled carry on related circuit of the lap and troubleshooting. Master electrical combination is learning the necessary foundation on electric.

Along with our country electrified railway and the rapid development of urban rail traffic, to adapt to the need for speed, digesting modified from theac regulated quickly replaced early point machine of the type of regulated dc point machine, and the domestic main lines of the application is turn point machine.

Electric turn point machine is rail control system of actuators, and the matching speed rail circuit mainly divided into three parts, namely indoor rail control circuit, rail action circuit and rail said circuit, the five wire circuits, indoor and outdoor contact with 5 lines of root cable named respectively.
