每日一点——城市直流电供应系统

每日一点——城市直流电供应系统。
Daily - City DC power supply system.
城市之间通过高压交流传输，有减少损耗的好处。但城市内，小区里的高压交流电的传输，这种好处不明显。反而造成极大浪费。——因为现代社会，越来越多的使用直流，除了大型电器，一般的电子产品，半导体之类的，都是直接使用直流电。而几乎每一个电器都有自带个转化器，把交流电变成直流电。就连我们的手机，多少个手机，就有多少 充电器。多少台电脑，就有多个PC电源。等等这些造成了极大的资源浪费。
Through high pressure exchange between cities, there are benefits of reducing loss. But in the city, the District of high AC transmission, the benefits are not obvious. But cause great waste. Because of the modern society, more and more use of DC, in addition to large electrical appliances, general electronic products, semiconductors and the like, are direct use of direct current. And almost every appliance has a built-in converter, the AC into dc. Even our phone, how many phone, how many charger. How many computers, there are multiple PC power. And so on these cause a huge waste of resources.

我的想法——城市里面小区楼房铺设直流电路，统一大多数电器的电压标准，在家居里设置直流端口，为我们的电子产品大大的减负。其实目前很多先进的楼盘都有两套供电系统，直流供电主要是用来智能监控的。
My idea, city residential buildings laying DC circuit, unified most electrical voltage standard, in home Curie set DC port, for our electronic products greatly reducing the burden. In fact, many of the advanced real estate are two sets of power supply system, DC power is mainly used for intelligent monitoring.

延伸——需要政府主导，电子和电器行业之间进行统一的标准规划。好处是明显的，低压安全，环保节能，同时会刺激新的高科技产业出现。改变人类的生活。
Extension - the need for government led, the electronic and electrical industry between the unified standard planning. The benefits are obvious, the low pressure safety, the environmental protection energy conservation, simultaneously can stimulate the new high tech industry to appear. Change human life.
