- Abstract
ZPW-2000 series track circuit matching equipment adopts 4 700 μf aluminum electrolytic capacitor to protect against traction current interference. Since it is difficult to troubleshoot aluminum electrolytic capacitors through convenient methods, it is urgent to develop an online test method for electrolytic capacitors. In this paper, an on-line test method of aluminum electrolytic capacitor of matching equipment based on the principle of digital bridge is proposed, and the on-site test application is carried out. By using this method, the performance parameters of aluminum electrolytic capacitors can be quantitatively evaluated without affecting the operation of track circuit equipment, providing reference for on-site maintenance.
