一种多功能的低压备用电源自投装置

备自投装置是电力系统中一种常用的安全自动装置,在发电厂、变电站及配电网络中均得到广泛的应用。本文介绍一种基于一般型备自投装置,增加了过流保护及过负荷联切功能的多功能备自投装置,本装置可用于进线开关相互自投以及进线开关与桥开关之间自投,适用于中低压供配电系统。

A Type of Multi-Function Low-Voltage Power Automatic Supply Device

Power Automatic Supply Device is a automatic safety device commonly used in power system, which have been widely applied in power plants, substations and distribution networks. Based on the general Power Automatic Supply Device, this paper introduce a new type of PASD, increasing over-current protection and over-load protection. This device can be supplied between switches used in entering-line, and between switches used in entering-line and bridge-switches, it applies to the low-voltage power supply system.
