电工基础笔记
基础的电工知识人体安全电压：36V以下安全跳闸电流: 30MA电工设备软件：天空直通车对电要有敬畏之心，不要用手去触碰。125mm 能拉进去触电，不要用手摸单相电流的计算公式：电流 = 功率/电压 例如：2.6KW 220v电压，电流=2.6*1000 / 220 = 11.8三相电流的计算公式： 电流=功率/电压/1.732/0.8（无功） 例如：18KW 380v电压，电流=18*1000 / 380 / 1.732 / 0.8 = 11.8 = 34生活中常用负载设备快捷计算电流：功率kw*2，例如：15KW的设备，30A

    in the article I looked at. And after this post rabbitmq-server line 85:

    I actually do have a couple of questions for you iff you don't mind.
    Could it bbe simply me or do a few of these remarks appear
    as if thry are left by brain dead people?
    :-P And, if you are wrriting at additional sites, I'd like too keep up with anything new
    you have too post. Would you list every oone of all your

    I believe everything posted made a great deal of sense. However, what about
    this? what if you were to write a killer post title?
    I mean, I don't wish to tell you how to run your website, however suppose you added a post
    title that grabbed people's attention? I mean 个人介绍 - Dcr163的博客 is kinda vanilla.
    You ought to look at Yahoo's home page and note how they create article titles to grab viewers interested.
    You might add a related video or a related pic or two to get people excited
    about everything've written. Just my opinion, it could make your
    blog a little livelier. faster indexing
