摘 要: | 由于拉闸限电,使用电单位内一些较重要部门的供电也不能得到保障。本系统即使用单片微处理器80C51设计一个应用于10Kv/0.4Kv系统的自动减载装置。此装置能在变电站用电总负荷超标时自动断开一条或多条非重要负荷的供电线路,使本站的用电总负荷被限制在一个给定的容量范围之内。这样可以使上一级变电站不至于因用电紧张而拉闸。

Abstract: | As limiting power by turning off pull - switch, some important departments can not guarantee the power supply .The system is an automatic reducing- load device applied in the sys- tem of 10KV/0.4KV by using single- chip processor 80C51 .The device can cut one or more wwimportant circuits when the total load of transformer substation beyoncl demand, which makes the total confined to a given volume. Thus, it can guarantee the power supply of upper substation. |
