一、概述机车运行途中比较突出的故障或者说机车诸多故障的综合反映是功率低或无功率。本文仅就功率低故障谈点看法。济南西机务段自1984年10月陆续配属95台ND_5机车,至1987年11月机车运用三年来,仅功率低故障有统计的就发生64次之多。造成机破24次,占电器机破的30％,临修53次,占电器临修的16％。给运输安全带来一定威胁,给运输生产造成较大经济损失。功率低故障可分为保护性故障和非保护性故障两种。所谓保护性故障,即“减少励磁”故障。这主要是考虑对于机车在运行途
First, an overview of locomotives on the way to more prominent fault or that a lot of locomotives a comprehensive reflection of the power is low or no power. This article only talk about low power failure point of view. Ji’nan west locomotive depot has been attached to 95 ND_5 locomotives since October 1984, and only 64 times as many as the low power failure occurred in statistics in November 1987 when locomotives were used. Resulting in machine broken 24 times, accounting for 30% of broken electrical machines, temporary repair 53 times, accounting for electrical repair of 16%. Bring a certain threat to the transportation safety and cause great economic losses to the transportation and production. Low power failure can be divided into two kinds of protective fault and non-protective fault. The so-called protective fault, that is, “reduce excitation” fault. This is mainly for the locomotive in operation
