厍斩奋703定位筋不允许焊接主筋出自哪本规范 -
樊发晨19320831719 ______ 定位筋不允许焊接主筋出自《钢结构设计规范》(GB50017-2003)第六章第6.2.5节,第6.2.5.3条.其中规定:“定位筋不得焊接在主筋上,定位筋的接头可以焊接在主筋的侧壁上”.
厍斩奋703pe=46.99kw,kx=0.8,ljs=67.08A电路系统图中式怎么计算出来的? -
樊发晨19320831719 ______ pe=46.99kw,kx=0.8,ljs=67.08A电路系统图中式怎么计算出来的?我觉得应该是楼上那样. http://www.henanlj.com/pe=46.99kw,kx=0.8,ljs=67.08A电路系统图中式怎么计算出来的?
厍斩奋703在纯电感电路电压电流波形图中,t=0时电压值为什么是幅值.什么意思呀. -
樊发晨19320831719 ______ 是不是震荡电路呀?有正值有负值,那只是代表两个方向而已.
厍斩奋703一道电路分析题,有图 -
樊发晨19320831719 ______ 这时是发生并联谐振,并联谐振时阻抗模为无穷大,如果你能让阻抗模无穷大就行,但目前我所遇到的电路好像都是调节电源角频率来达到谐振的,即使电源频率W=1/sqrt(LC).不知道你这道题出自哪里?
厍斩奋703电气接线图什么意思 -
樊发晨19320831719 ______ 电气原理图是根据控制线图工作原理绘制,具有结构简单,层次分明.主要用于研究和分析电路工作原理,要想看电气原理图要先清楚其中的电气原理及其符号所表示的含义.看原理图先看主电路,再看控制电路.对于控制电路要熟悉典型控制...
厍斩奋703维修电工以电气原理图和安装接线图和什么最为重要 -
樊发晨19320831719 ______ 二个都重要 检查故障用原理图 具体找故障点有接线图当然方便了 尤其是工厂电气 接线及走向 以及元件位置较复杂 有接线图就方便得多 不过有原理图好分析
厍斩奋703电气接线图怎么看? -
樊发晨19320831719 ______ 先把原理图读懂记熟,再看接线图就容易多了.看懂接线图先得了解接线图的绘制规则和内容. 接线图一般表达电气设备和元器件的相对位置、文字符号、端子号、导线号、导线类型、导线截面等. 所有的元器件都按其所在的实际位置绘制在...
厍斩奋703怎样看懂电气接线图 -
樊发晨19320831719 ______ 首先,你要懂得电气控制回路、主回路的基本定义;知道各个元器件的表示符号,参考其标识字母;一般来说,不管图纸中回路的绘制是横向或是纵向,在其上部或者右侧都有功能说明.低压回路一般没有说明.此外,控制回路中各种电气“点”的图示状态都是其正常状态,即是元器件尚未发生动作的状态.例如按钮的常开点,图示为非闭合状态,当按下按钮时即按钮动作时,其常开点会闭合,根据按钮类型返回或者闭锁不返回.
厍斩奋703电气二次接线图怎么看 -
樊发晨19320831719 ______ 原发布者:wjsdxb301 轻松看懂电气二次接线图和原理图一次电路图中元器件动作均是由二次控制图来控制动作,对于二次原理图看图步骤是从左至右、从上至下逐步熟悉了解掌握.二次接线图的内容二次接线图是由二次设备所组成的低压回路...
