Problems solved by technology

The megohmmeter needs to be cranked by hand, which is not only inefficient, but also the test voltage is unstable and the accuracy is not high
There are hundreds of signal cables to be tested in a station. Signal workers have a large workload and low efficiency, and it is easy to connect wrong signal cables, resulting in inaccurate measurements or other failures. It is difficult to grasp the true insulation status of signal cables.

Description

technical field [0001] The invention relates to a railway signal system, in particular to an on-line test system for the ground insulation of railway signal cables. Background technique [0002] In recent years, with the great development of China's high-speed railway and urban rail transit, its core control equipment - signal equipment has also been widely used. Signal equipment is divided into indoor equipment and outdoor equipment, and the two are connected by signal cables. If the signal cable is not well insulated from the ground, it will affect the normal operation of the signal equipment, and it will cause the fuse of the power supply screen to blow or the circuit breaker to trip, causing large-scale equipment failure. Therefore, the insulation test of the signal cable to the ground is an important function to ensure the stable operation of the signal equipment. [0003] The insulation of the railway system has been manually tested using a megohmmeter (commonly know...
