Problems solved by technology
However, a short circuit caused by a damaged insulation layer will cause a circuit failure on the track. It is usually difficult to judge whether the insulation performance of the track is good by visual inspection, and the insulation inspection method summarized in the prior art is easily restricted by temperature and environment, and has a large workload and poor operability. high difficulty
In particular, the adhesive insulation and other equipment cannot be disassembled, and the electrified railway cannot be judged by the multimeter resistance test, which makes it very difficult to test the insulation performance of the track

The invention discloses a railway track insulating property test method and test device. The railway track insulating property test method includes the steps: a) utilizing voltage test equipment to test the voltage between two first tracks (11) in the first segment of railway track to obtain a first voltage value; b) performing short circuit between any one first track (11) in the first segment of railway track and a track joint clamping plate (3) which is connected with the first track (11), and utilizing the voltage test equipment to test the voltage between the two first tracks (11) in the first segment of railway track to obtain a second voltage value; and c) comparing the first voltage value with the second voltage value. The railway track insulating property test method is simple in operation and is high in feasibility and reliability.
Description
technical field [0001] The invention relates to an insulation performance testing method, in particular to a railway track insulation performance testing method and a testing device. Background technique [0002] Electrified railways have been widely used. In the electrified railway system, two adjacent sections of rails are connected by fishplates (ie, track joint splints), bolts and other components, and between adjacent two sections of steel rails and each An insulating layer is also arranged between the section steel rail and the fishplate, so that two adjacent sections of steel rail are insulated from each other, and each section of steel rail and the fishplate are kept insulated. However, a short circuit caused by a damaged insulation layer will cause a circuit failure on the track. It is usually difficult to judge whether the insulation performance of the track is good by visual inspection, and the insulation inspection method summarized in the prior art is easily res...
