Embodiment Construction
[0018] The insulation detection method of the ballastless track Borg plate, 1. Place the tested Borg plate on a flat test platform; take two steel rails longer than the tested plate and place them on the rail bearing platform of the plate, and make the rails on the track buckle (At this time, the gauge of the two rails is equal to 1.435m); one end of the two rails is connected with a wire, and the inductance value L and the effective resistance value R of the two rail circuits are tested from the other end of the two rails, and the test frequency is a practical carrier frequency. (that is, the signal frequency actually transmitted by the railway track); 2. Move the rail out of the Borg plate under test, and insulate or suspend the two rails to maintain a gauge of 1.435m and make the bottom of the two rails on the same plane. One end of the two rails is still connected with a wire, and the inductance value L0 and the effective resistance value R0 of the two rail circuits are tes...

The invention relates to an insulation detecting method and the insulation detecting device for borg plate without ballast rail, belonging to the detecting technology for borg plate without ballast rail. It solves the problem that at present there are not insulation detecting method and device for borg plate. The insulation detecting method is that firstly inductance and effective resistance is measured when there is and there is not plate under the track; then change rate of two inductances and effective resistances is calculated; when the change rate of inductance is in +-3% and the change rate of effective resistance is below 10% the borg plate is qualified in insulation performance. The detecting device comprises support and two rails insulated with the support and fixed on the support. Bottom face of two rails is in the same plane and the distance of rails is 1.435m. Ends of two rails are connected by wire and the other ends of two rails are connected with resistance and inductance tester. The insulation detecting method for borg plate without ballast rail is new, special, scientific, reasonable and simple. It fills the blank that there is no insulation detecting method for borg plate at present.
Description
technical field [0001] The invention relates to a detection technology for a ballastless track Borg plate, in particular to an insulation detection method and an insulation detection device for a ballastless track Borg plate. Background technique [0002] The German ballastless track Borg plate production technology introduced by the Ministry of Railways is currently the most advanced ballastless track system technology in the world. Due to the characteristics of signal transmission of ballastless track circuits in Germany (cable transmission), there is no special requirement for the insulation performance of the Bourg board itself, and of course there is no insulation test for the Bourg board. After the introduction, in order to adapt to the signal transmission characteristics of my country's track circuit (steel rail is the signal transmission carrier), Borg boards must have good insulation properties. The ballastless track Borg slab currently used in the Beijing-Tianjin ...
