Mutual inductance type real-time on-line diagnosis and repair system for reliability of long-distance multi-node train line and use method thereof

Abstract

The invention discloses a mutual inductance type real-time on-line diagnosis and repair system for the reliability of a long-distance multi-node train line and a use method thereof. The system comprise a host and a slave, wherein an electrical grinding part is arranged on the host and is connected to detected line pairs; a grinding current absorbing part and a slave end voltage detecting part are arranged on the slave and are respectively connected to the detected line pairs; and the grinding current absorbing part is connected with the electrical grinding part through a trigger control wire. Compared with the prior art, the invention has the benefits that: firstly, the real-time on-line detection and the real-time on-line grinding for the reliability of the long-distance multi-node train line are achieved, the phenomenon that the usability of the line is influenced due to high-frequency detection and line interrupting operation can be avoided, the overhaul and the detaching for maintenance for the parts of the equipment can be avoided, the repair efficiency and the reliability are greatly improved and the loss rate and the cost expenditure are reduced; and secondly, the system has a simple and contact integral structure and is convenient and easy to operate.

Description

technical field [0001] The invention relates to a system for real-time on-line diagnosis and repair of train line reliability and its application method, belonging to the technical field of electrical automation, in particular to a long-distance multi-node train line involving electrical switches, relays and other contacts and conductive contact surfaces of electrical connectors Reliability mutual inductance real-time online diagnosis and repair system and its application method. Background technique [0002] In the field of electrical automation, various switching components are widely used, which has an important impact on the reliability of many key circuits that operate continuously online. As we all know, a train is generally composed of multiple carriages, and some logic control signal lines and signal control ring lines need to run through the entire train. Therefore, multiple segmented connectors need to be installed on the train line to facilitate train disassembly ...

AI Technical Summary

Problems solved by technology

In the existing technology, the traditional repair method is to disassemble the switch element and disassemble it, take out the pin of the contact or connector, and manually grind the conductive contact surface, but for some fully sealed switchgear, it can only be scrapped replace

This traditional grinding method needs to disassemble and reassemble the switch elements, which is complicated and labor-intensive, and it is difficult to ensure that the fit clearance after reassembly can be restored to the original best state; on the other hand, grinding will also damage the contact copper surface There is additional wear and tear, and usually the contacts need to be scrapped after only one or two grinding repairs; at the same time, contact grinding has higher technical requirements for operators
