摘要
为了帮助现场技术人员快速入门,将二次回路按照电压等级和功能进行分解、将复杂的二次电路简化后,介绍了煤矿变电所使用的直流屏操作电源、自带PT的交流操作电源、干式变压器提供交流操作电源的三种电源结构及作用,有助于快速掌握煤矿10 kV变电所供电系统。
In order to help field technicians to learn quickly,the secondary circuit was decomposed according to the voltage level and function,Three kinds of power supply structure and function of DC operation power supply,AC operation power supply with PT and AC operation power supply with dry type transformer used in mine substation were introduced,which is helpful to quickly master the power supply system of 10 kV mine substation.
