一、概述 SS_4改进型电力机车电路包括主电路、辅助电路、有接点控制电路、110V电源电路和电子控制电路五大部分。本文介绍的是前四部分内容的一些特点。 SS_4改进型电力机车电路中的电气设备代号,全面执行GB7159—87《电气技术中的文字符号制订通则》中的规定。为便于记忆,采用流水数字加文字符号的办法,考虑到SS_1和SS_4型机车的传统,其流水数字避免了重复,使机车每一电气设备中的代号都对应唯一的流水数字。
I. Overview SS_4 modified electric locomotive circuit includes the main circuit, auxiliary circuits, contact control circuit, 110V power supply circuit and electronic control circuit five parts. This article describes some of the features of the first four sections. SS_4 modified electric locomotive circuit electrical equipment code, the full implementation of GB7159-87 “electrical technology in the development of general rules” in the text. In order to facilitate the memory, the use of digital watermarks and symbols approach, taking into account the tradition of SS_1 and SS_4 locomotives, the digital flow to avoid duplication, the locomotive code for each electrical equipment corresponds to a unique number of water.
