画简单电路图的方法

画简单电路图的方法 电子知识 电路图(5509) 画简单电路图的方法: (1)电流分路法 此方法的要点是:从电源的正极出发，顺着电流的方向找，直到电源的负极为止。不管电路如何弯曲，只要是电流不分路，即电流从一个用电器流向另一个用电器，一直流下去，那么用电器就是串联接法，组成的就是串联电路。如果电路在某点出现分路，表明这个电路中既有干路，又有支路，那么电流通过支路上的用电器后将在另一点汇合，在回到电源的负极。当干路上没有用电器，而每条支路上只要一个用电器时，这些用电器就组成并联电路。 (2)节点法 对于具有串.并联电路初步知识的同学来说，从 规范 编程规范下载gsp规范下载钢格栅规范下载警徽规范下载建设厅规范下载 的电路中看出用电器的接法是很容易的。但当面对的是一个不规范的电路，特别是电路中的导线在多处交叉相连时，初学者往往会感到困惑。 识别这种电路可采用“节点法”。所谓节点指的是电路中那些“导线交叉相连”的点，包括分流点和汇流点。 利用节点法识别电路的具体步骤是: a.先找出电路中的所有节点，并分别用字母,或数字,表示。 b.将所有用一根导线直接相连,不经过用电器,的节点视为同一节点。并改用同一字母,或数字,表示。 经过以上两步的处理，从图06-2中不难看出，灯L1、L2、L3的两端，都是一端接在电路的A点上，另一端接在电路的D,B,点上，因而灯L1、L2、L3是并联的。 连接电路 after the concrete has been poured, placement and size of embedded part installation again to retest checking, confirmed by the supervisor after passing to acceptance among the buried together, its acceptance of inspection record should be the gate and headstock gear items information. If after inspection found buried installation of unqualified, rework should be directed by the supervisor, the measures and methods of its processing should be approved by the supervisor.

After you install quality assessment recording supervisor sign, as the acceptance of the contract information. 2) gate and the opening and closing machine installation completed, and by test and commissioning qualified Hou, 根据电路图连接实物，是同学们应该具备的一种电学的实验技能。连接电路通常采用以下三种方法。 (1)电流流向法 从电源的正极开始，沿着电流的流向依次连接实物，直到电 源的负极。连接串联电路时采用这种方法既快捷又准确。 (2)先支路后干路法 顾名思义，这是连接并联电路常采用的一种方法。其过程是:先从电路图中找出电路的分流点和汇流点，视它们为各个支路的“头”和“尾”,把各个支路上的元件按电流流入方向连好，电流流入端是支路的“头”，电流流出端是支路的“尾”，并将各个支路 的“头头”相接，“尾尾”相连,再把干路上的元件按电路图中的顺序接在分流点和汇流点之间,最后把各个支路的“头”和“尾”分别与分流点和汇流点相连。 (3)先通后补法 从电源的正极开始，沿着电流的流向，将干路中的元件和某一支路的元件用导线接通，先形成一条电流的路径，找出分流点和汇流点的位置,然后将其他各个支路中的元件连好，补接在分流点和汇流点之间，再形成所有电流的路径。 维修人员常遇到无图纸的电子产品，需要根据实物画出 电路原理 通信电路原理答案变频空调电路原理图变频空调维修电路原理变频空调通讯电路原理运放差分放大电路原理 图。这也是初学者必须掌握的基本功，以下介绍有关方法与技巧。1.选择体积大、引脚多并在电路中起主要作用的元器件如集成电路、变压器、晶体管等作画图基准件，然后从选择的基准件各引脚开始画图，可减少出错。 2.若印制板上标有元件序号,如VD870、R330、C466等,，由于这些序号有特定的规则，英文字母后首位阿拉伯数字相同的元件属同一功能单元，因此画图时应巧加利用。正确区分同一功能单元的元器件，是画图布局的基础。 after the concrete has been poured, placement and size of embedded part installation again to retest checking, confirmed by the supervisor after passing to acceptance among the buried together, its acceptance of inspection record should be the gate and headstock gear items information. If after inspection found buried installation of unqualified, rework should be directed by the supervisor, the measures and methods of its processing should be approved by the supervisor. (4) gate, and stopped dirt gate and the opening and closing machine installation quality of check and acceptance 1) in gate and the opening and closing machine installation process in the, with supervision people by provides of installation technology conditions, on this contract all gate and the opening and closing machine Project installation of welding quality, and coated loaded quality, and installation deviation and test and commissioning results, installation quality project for check and quality evaluation, and for good records. After you install quality assessment recording supervisor sign, as the acceptance of the contract information. 2) gate and the opening and closing machine installation completed, and by test and commissioning qualified Hou, 3.如果印制板上未标出元器件的序号，为便于 分析 定性数据统计分析pdf销售业绩分析模板建筑结构震害分析销售进度分析表京东商城竞争战略分析 与校对电路，最好自己给元器件编号。制造厂在设计印制板排列元器件时，为使铜箔走线最短，一般把同一功能单元的元器件相对集中布置。找到某单元起核心作用的器件后，只要顺藤摸瓜就能找到同一功能单元的其它元件。 4.正确区分印制板的地线、电源线和信号线。以电源电路为例，电源变压器次级所接整流管的负端为电源正极，与地线之间一般均接有大容量滤波电容，该电容外壳有极性标志。也可从三端稳压器引脚找出电源线和地线。工厂在印制板布线时，为防止自激、抗干扰，一般把地线铜箔设置得最宽,高频电路则常有大面积接地铜箔,，电源线铜箔次之，信号线铜箔最窄。此外，在既有模拟电路又有数字电路的电子产品中，印制板上往往将各自的地线分开，形成独立的接地网，这也可作为识别判断的依据。 5.为避免元器件引脚连线过多使电路图的布线交叉穿插，导致所画的图杂乱无章，电源和地线可大量使用端子标注与接地符号。如果元器件较多，还可将各单元电路分开画出，然后组合在一起。 6.画草图时，推荐采用透明描图纸，用多色彩笔将地线、电源线、信号线、元器件等按颜色分类画出。修改时，逐步加深颜色，使图纸直观醒目，以便分析电路。 7.熟练掌握一些单元电路的基本组成形式和经典画法，如整流桥、稳压电路和运放、数字集成电路等。先将这些单元电路直接画出，形成电路图的框架，可提高画图效率。 8.画电路图时，应尽可能地找到类似产品的电路图做参考，会起事半功倍的作用 IBIS模型是一种基于V/I曲线对I/O BUFFER快速准确建after the concrete has been poured, placement and size of embedded part installation again to retest checking, confirmed by the supervisor after passing to acceptance among the buried together, its acceptance of inspection record should be the gate and headstock gear items information.
