本文介绍的是牵引电机数据库年报和半年报中未能反映的情况,分两部分内容叙述。一、新电机故障及其可靠度这里所指的“新电机”是1981年和1982年出厂的电机,运用时间统计截止1984年6月。1983年出厂的电机因运用时间较短,暂不分析。(一)ZQDR-410牵引电动机1.永济电机厂(以下简称永济厂)(1)1981年出厂的电机1981年共生产301台,运用到1984年6月止,总故障台次为36。对整台电机可按指数分布对其可靠性指标作粗略
This article describes the traction motor database annual report and semi-annual report failed to reflect the situation, divided into two parts described. First, the new motor failure and its reliability Here refers to the “new motor” is the motor manufactured in 1981 and 1982, the use of time statistics as of June 1984. 1983 factory motor due to the use of a shorter time, temporarily not analyzed. (1) ZQDR-410 Traction Motor 1. Yongji Motor Factory (hereinafter referred to as Yongji Factory) (1) In 1981, a total of 301 electric motors were delivered in 1981, which were used until June 1984, with a total of 36 . The entire motor can be indexed by its reliability index for rough
