电流的形成原理广义的电流的本质是电荷的定向移动，电荷的载体可以是电子，也可以是离子。也可以说电流是导体材料中的自由电子在电源产生的电场的作用下作定向运动。以金属导体为例，一切固态金属都是晶体，在它的空间点阵的结点上 ...JFEYH10KV高压电机引接线JFEYH10KV电缆JFEYH10KV电线
The essence of the current formation principle is that the essence of the current is the directional movement of the charge, the carrier of the charge can be the electron, and it can also be an ion. It can be said that the current is under the effect of the directional movement of free electrons in a conductor material in the field of power generation in the. In the case of metal conductors, all solid metals are crystals, on the nodes of its space lattice.

Using two double switches to control a lamp circuit diagram to read in two places
用两只双联开关在两处控制一盏灯电路图识读方法用两只双联开关在两处控制一盏灯的电路如图所示。图中的N、L分别表示电源的零线和火线，FU为熔断器，Q1、Q2为双联开关，HL为灯，图中它处在断路状态。当打开开关Q1(或Q2)接通电源后，电源通过FU→Q1→Q2→HL，灯点亮 ...
Two double switches are used to control a light circuit diagram reading at two places. The circuit of a lamp is controlled in two places with two double switches, as shown in the diagram. The N and L in the diagram represent the zero line and fire line of the power supply. The FU is a fuse, the Q1, the Q2 is the double switch, the HL is the lamp, and it is in the circuit breaker state. When the switch Q1 (or Q2) is switched on, the power supply is lit through the FU - Q1 - Q2 - HL.

变压器差动保护基本原理及作用
Basic principle and function of transformer differential protection
差动保护是根据“电路中流入节点电流总和等于零”的原理制成的。在绕组变压器的两侧均装设电流互感器，其二次侧按循环电流法接线，即如果两侧电流互感器的同级性端都朝向母线侧，则将同级性端子相连，并在两接线 ...
The differential protection is based on the principle of "the sum of the current in the circuit is equal to zero". The two sides of the winding transformer are equipped with current transformer, and the secondary side is connected by the cyclic current method. That is, if the side ends of both sides of the current transformer are facing the bus side, they will be connected to the same level terminals and connected at two.

电气二次控制线路中380伏变120伏控制变压器输出端端子上可以一相接地吗？
Can the output terminal of the 380 volt 120 volt control transformer in the electrical two control line be connected to each other?
电气二次控制线路中380伏变120伏控制变压器输出端端子上可以一相接地吗？控制变压器（俗称隔离变压器或者安全变压器）是用来改变交流电压的设置，由铁芯和线圈线成。它不仅能改变交流电的电压，同时还能改变阻抗，在不超设计功率时，还可改变电流. 在不同的环境下，变压器的用途也不同。
Can the output terminal of the 380 volt 120 volt control transformer in the electrical two control line be connected to each other? The control transformer (commonly known as isolating transformer or safe transformer) is used to change the AC voltage, which is made of iron core and coil line. It can not only change the voltage of alternating current, but also change the impedance. It can also change the electric current when the power is not designed. In different environments, the use of transformer is also different.
