在东方红型内燃机车上,逐步采用了一些电子装置。机车上的电机电器产生的感应电势对各种电子装置一直是一个很大的威胁。感应电势对电子装置的危害,有时是造成电子元件的过电压击穿,有时是引起电子装置误动作。为了提高电子装置的可靠性,几年来,我们对机车上常用的几类电感性电器产生的感应电势,做了一些分析、试验和研究,采取了一些消除感应电势的措施,取得了较好的效果。本文将对接触器、中间继电器、电磁阀、点火线圈等几类电器的感应电势,给出一些试验数据;并对感应电势在电气系统中的传播和衰减做一些分析;对消除感应电势的几种方法做一
In the East of the red diesel locomotive, the gradual adoption of some electronic devices. Induction motor locomotive electrical potential for a variety of electronic devices has always been a great threat. The potential of the sensing potential to the electronic device is sometimes caused by over-voltage breakdown of the electronic component, sometimes causing malfunction of the electronic device. In order to improve the reliability of electronic devices, in recent years, we have done some analysis, experiment and research on the induced potential generated by several types of inductive electrical appliances commonly used on locomotives. Some measures have been taken to eliminate the induced potential and better effect. In this paper, some test data are given for the induced potentials of several types of electrical appliances such as contactors, intermediate relays, solenoid valves and ignition coils; some analysis is made on the propagation and attenuation of induced potential in the electrical system; One way to do this
