Description

Technical Field

[0002] During the railway capacitance detection process, various interference factors may be encountered, which may affect the accuracy and reliability of the detection.

[0003] Currently, railway capacitance testing typically uses a single probe. However, a single probe cannot perform continuous measurements. Once the probe requires maintenance or calibration, the measurement process is interrupted. Continuous use of a single probe can cause probe temperature to rise, resulting in thermal drift, which interferes with measurement accuracy and increases probe fatigue and wear, thus shortening the probe's lifespan. Utility Model Content

[0004] In light of this, the present invention aims to provide an interference-resistant railway capacitance detection device to address the problem of a single probe being unable to perform continuous measurements. Once the probe requires maintenance or calibration, the measurement process is interrupted.
