我司现有电机车所用的电源,长期以来均使用传统的电动机发电机组。这种变流装置的主要缺点是:机组效率低,电压调整率大,经常出现毛病,加重维修人员的负担。为了提高系统的安全经济运行水平,我们采用可控硅和硅整流装置作为电机车牵引电源,甩掉原有老、大、笨的直流机组及其附属装置。目前上述装置已在我司普遍使用,并已取得了较好的效果。本文仅对使用的效果及过流保护等问题谈一些看法,至于其他问题,因一般资料都有详细介绍,不再详述。
Our existing electric locomotive used in the power supply, have long used the traditional motor generator. The main drawback of this converter device is: low efficiency unit, voltage regulation, often problems, increase the burden on maintenance personnel. In order to improve the safe and economical operation of the system, we use thyristor and silicon rectifiers as traction electric locomotives to get rid of old, large and stupid DC units and their attachments. At present, these devices have been widely used in our company, and have achieved good results. This article only on the use of effects and over-current protection and other issues to talk about some of the views, as for other issues, because the general information is described in detail, not elaborate.
