俄罗斯各铁路线出现装备有复杂电子控制系统的机车，要求在机务段内建立与这种设备相适应的修理用和诊断用的试验台。但是最有发展前途的方向之一是创建自动化诊断系统，它既可用于直接在电力机车上检查该设备，又可用于在车间内调整和修理该设备。最近20年内BЛ80P系交流电力机车以及不久前出现的BЛ85电力机车已获得广泛的应用。现在在东西伯利亚铁路上正在进行装有类似于BЛ85电力机车的控制系统的B65交流客运电力机车的试运行。与以前的机车不同的是：以前机车电动机上的电压是用总开关的接触器分级转换牵引变压器绕组的方法来调整的，而新型电力机车则采用崭新原理的主四段电压调整系统（图1）。本文介绍BЛ80P和BЛ85电力机车电子设备的自动化技术诊断系统（ACTЛ）该系统于1985年首先在克拉斯诺雅尔斯克铁路博戈托尔机务段内采用，而现在已在克拉斯诺雅尔斯克、东西伯利亚、远东和贝加尔─阿穆尔等铁路的7个机务段内运用。介绍了电力机车设备的二级诊断工艺，并研讨了目前所用的自动化技术诊断系统的仪表装置。
The presence of complex locomotives equipped with sophisticated electronic control systems on all railway lines in Russia requires that test stands for repair and diagnostics be established in the locomotive depot in accordance with such equipment. But one of the most promising directions is to create an automated diagnostic system that can be used both for inspecting the equipment directly on the electric locomotive and for adjusting and repairing the equipment in the shop floor. In the recent 20 years, the BЛ80P AC electric locomotive has been widely used as well as the recently appeared BЛ85 electric locomotive. Commissioning of a B65 AC passenger electric locomotive with a control system similar to the BЛ85 electric locomotive is now proceeding on the Eastern Siberia Railway. Unlike the previous locomotives, the voltage on the locomotive motor was adjusted by the contactor of the main switch to convert the traction transformer windings, while the new electric locomotive adopted a new principle of the main four-stage voltage regulation system ). This article introduces the automated technology diagnostic system (BES) of the BЛ80P and BЛ85 electric locomotive electronic equipment. The system was first adopted in 1985 in the Bogotol Depot of the Krasnoyarsk Railway, and is now implemented in Krasnoyarsk , East Siberia, the Far East and Baikal - Amur and other railways 7 depot use. This paper introduces the secondary diagnosis technology of electric locomotive equipment and discusses the instrumentation of the automated technology diagnosis system used at present.
