Abstract

Abstract:

The accurate determination of the pick-up voltage and release voltage of railway signal relay is directly related to the products reliability evaluation.Firstly,The measurement principle of pick-up voltage and release voltage is described.Then the measurement system with the function of programming coil exciting voltage and capturing the contact voltage waveform is developed.The pick-up voltage,release voltage and reverse pick-up voltage parameters of railway signal relay are measured automatically.Taking a voltage-type relay as an example,the effects of coil voltage step and coil voltage step delay on the results are analyzed.Finally the measurement method considering both measurement accuracy and efficiency is ascertained.

Key words: railway signal relay, release voltage, pick-up voltage, automatic test
