目前居民楼楼梯照明一般是通过计量或未计量的专用回路供电,前者电费由有关住户平均分摊,后者由单位承担。这种用电“大锅饭”的管理方式,使住宅楼楼梯灯彻夜常明,甚至白天也无人关灯,这是一种很大的浪费。针对上述情况,笔者经过多方案的对比,最后设计了楼梯照明节电自动断电器。该装置基本上较好地解决了上述问题。每单元根据层数,投资和节能等方面综 At present, the lighting of residential buildings is generally powered by metered or non-metered dedicated circuits. The former is divided equally among the households and the latter is borne by the units. This kind of electricity “big pot” management method, so that the stairs of residential buildings all night and night, and even no one turned off the lights during the day, which is a great waste. In view of the above situation, the author compared the various programs, and finally designed a stair lighting energy-saving automatic circuit breaker. The device substantially solves the above problems. According to the number of layers per unit, investment and energy efficiency
