Background

In most of the current subway projects, a train adopts a direct current power supply mode, a potential difference can exist between a running rail and the ground, and the highest potential difference can reach DC90V (in a normal operation and under a maximum load state) or DC120V (when a traction station is disconnected and power is supplied by a large double side formed by adjacent traction transformers), so that a potential difference which causes safety hazards to passengers exists between a platform door and the train, and if the passengers touch the platform door and the train door at the same time, safety injuries can be caused. The "design of land (GB 50157-2013) article 26.5.7: the platform door and the train compartment should be kept at equal potential, and when the platform door and the train compartment have connection requirements, the equal potential requirements should meet the following regulations: under normal conditions, the platform door metal component which can be touched by a human body is insulated from a station structure, the insulation resistance between a door body and the station structure is not less than 0.5M omega, and the platform door on each side is kept at the same electric potential as a whole.

At present, the subway full-height platform door adopts an installation scheme that an upper telescopic insulating sleeve is connected with a civil engineering top beam, and an insulating cushion block is additionally arranged on a lower base; the half-height platform door only adopts the installation scheme that the lower base is added with the insulating cushion block. Meanwhile, a ground insulating layer is arranged at a position 10mm away from the edge of the platform door body. At present, a batten baffle or an L-shaped baffle is generally adopted to isolate a platform door base and a ground insulating layer implementation area, and the isolation length is equal to the total length of a platform door. There are the following disadvantages:

1. after the platform door base is installed, the platform insulating layer of the adjacent door bodies can be implemented. Because the existing structural layer is uneven, cement mortar can leak into the space of the platform door base through a large gap between the batten baffle or the L-shaped baffle and the structural layer, so that the base is polluted, and the insulation failure of the platform door base is easily caused.

2. Influenced by the existing rugged structure layer, the top height of the batten baffle or the L-shaped baffle cannot be adjusted. If the local part is higher than the ground elevation, additional cutting is needed, and the cutting occupies the gap space sealed by sealing the opening with the insulating glue, the opening cannot be effectively closed, so that the sewage enters the gap to break the insulating effect; if the baffle height then can't play the supporting role to the insulating cement at the top, the problem that the insulating cement collapses to the clearance commonly appears in operation back station ground.

3. The batten baffle or the L-shaped baffle is not fixed, so that the gap between the concrete leveling layer and the insulating layer and the platform door base cannot be guaranteed to be uniform, and the minimum creepage distance is insufficient.

4. In addition, if the batten baffle is adopted, after concrete pouring is finished, the batten baffle is installed between concrete and the platform door base and cannot be thoroughly removed.

5. The implementation effect of arranging the batten baffle or the L-shaped baffle in the field construction is greatly influenced by human factors, and the construction process is complex and cannot be effectively controlled.

Therefore, the insulation scheme of the platform door base has no problem in theory, but after the insulation layer is installed, the insulation failure of the bottom of the door body occurs, the requirement that the insulation resistance value is greater than or equal to 0.5M omega cannot be met, and the problem is ubiquitous in the rail transit industry at present.
