5、电缆敷设时允许弯曲半径应不小于电缆外径的4倍习可不能像是看小说那样看完就过了,作为电工学的开篇,同时作为电工技术这个特殊作业工种,理解并记住每个知识点是很重要的,因为电工基础里面很多都是理论知识,前面的没掌握好后面的都比较难懂。不啰嗦了,和笔者一起复习一下前面的三节课吧:JFEM电缆电机引接线
Xi can not like reading novels as before, as Electrotechnician begins, at the same time as the special electrician technology works, understand and remember each knowledge point is very important, because there are a lot of electrical engineering basic theory knowledge, the front didn't grasp well behind the more difficult. Not long winded, the front and the author review together the three classes:
*课讲的是:《直流电路、电路的组成、电路图的基础知识》,需要理解什么是电路(三大组成部分),以及电路的作用。还记得这些内容吗?什么是电路?电路就是电流流通的路径。他的作用是传递和分配电能,比昂试点嗯那个和其他形式的能量相互转换。电路3大组成部分:电源、负载、导线。
The first lesson is about the composition of DC circuit and the basic knowledge of circuit diagram. We need to understand what is the three components of the circuit and the role of the circuit. Do you remember the content? What is a circuit? The circuit is the path of current circulation. His role is to transfer and distribution of electric energy, the pilot well Bion and other forms of energy conversion. The 3 parts of the circuit are power, load and wire.
第二课讲的是:《什么是电流?电流计算公式和单位换算及电流方向讲解》,主要内容是:什么是电流?物质中带电粒子定向有规则的移动就形成了电流。电流的方向:正电荷移动的方向规定为电流的实际方向。还有电流在电路中的符号大写字母“I”以及计算公式I=q/t,还有就
The second lesson is: "what is the current?" The current calculation formula and unit conversion and current direction explanation, the main content is: what is the current? An electric current is formed by a regular movement of charged particles in a matter. The direction of the current: the direction of the positive charge movement is defined as the actual direction of the current. There is also the symbol "I" of the current in the circuit and the formula I=q/t.
