Protection switch products

In order to ensure the safety of train, the train must be inserted into the door switch station in some parts, by some route conditions to work together to achieve safety protection, the protection switch set is not in the arrangement of route, route arrangement must carries on the drive control (or manipulation) and be locked, the position of the switch circuit by check (for true) and locked at the door after the prescribed position, it can achieve a complete row route route locking and opening signal. According to the use of protective switch and protection requirements are different, can be divided into the following situations:

Stop port 1 is provided with 6 per thousand under ramp (though not enough or 6 per thousand, but the presence of train braking difficult entrance to the station) the first group switch designed for protection switch, the door can be opened to the point positioning safety line, special line, evacuation line.

With the successive route terminal 6 per thousand down the ramp, to prevent the train into the station out station not braking signal, in other way, a door switch, the door switch positioning can open security lines, special lines, lines, to the refuge, to the station along the junction into the mouth. This is the drive circuit switch.

With the successive route terminal 6 per thousand down the ramp, a translational protection switch, this switch circuit is not driven by manipulation, but artificial manipulation, but this switch connected car in 6 per thousand in route still checks its position in general such switch extension route display terminal, opened by positioning display extension route, (outside show route can only see the continuation of the receiving route and signal light, not to see the continuation of route band).

In line with the shunting and special line and are often busy shunting line and line wire pulled at the access interface part. The design of switch for door switch, to avoid shunting car shunting in column station transferred line, the door switch door positioning generally open to the safety line dedicated or shunting train pulling line, running line etc.).

Through the crossover of two groups of double action switch, designed for mutual protection switch, one group in the anti ranking route is another group must guard in position, to avoid a turnout in reverse, another group of turnouts also arranged reverse approach, resulting in the crossover. The formation of "cross" collision, another group is on, buffer side punching efforts crossing the line in the cross slide vehicle at the side blanking process, reduce side punching loss.

The products have been exported to the United States, France, Canada, Indonesia, Russia, Vietnam, Australia, South Korea, Iran and other countries, to obtain customer acclaim.
