江苏春晨电缆有限公司电电缆桥架和弱电电缆桥架的区别
The difference between the bridge frame of electric cable and the bridge of weak electric cable
强电电缆桥架和弱电电缆桥架有什么区别：1，众所周知，电缆桥架是是用来走电缆的，电气里的电缆暗敷时（埋地或走楼板、墙里等）一般用镀锌钢管或塑料管做保护管，但明敷的时候，一般走桥架，比如，在厂房梁下三百左 ...JEM电机引接线电缆桥架和弱电电缆桥架的区别
Electric cable bridge and weak cable tray. What is the difference between the 1, as everyone knows, cable tray is used to take the cable, electrical cable in the dark apply (or go underground floor, wall etc.) generally used in galvanized steel or plastic pipe protection tube, but when laid, usually go bridge, for example, in three hundred the left beam plant...

三相四线怎么接线？三相四线电表接线图JEM电机引接线电缆桥架和弱电电缆桥架的区别
How does the three-phase four wire connection? Wiring diagram of three phase four wire electric meter
三相四线怎么接线？三相四线电表接线图首先你得明白什么是三相四线制供电电路：三相四线制指三相交流供电中有三根火线（U、V、W表示），一根零线（N表示）。每两条火线之间电压380V，称为线电压，任何一根火线与零线的电压为220V，称为相电压。所以，220V ...
How does the three-phase four wire connection? The connection diagram of three phase four wire electrical meter shows you first understand what three-phase four wire power supply circuit is: three phase four wire system. Three phase AC power supply has three fire lines (U, V, W), and a zero line (N). The voltage between every two lines of fire is 380V, called line voltage, and the voltage of any line of fire and zero line is 220V, which is called phase voltage. So, 220V...

三相四线零线怎么接？三相四线中零线的作用JEM电机引接线电缆桥架和弱电电缆桥架的区别
How does the three phase four line zero line connect? The effect of zero line in the three phase four line
三相四线零线怎么接？三相四线中零线的作用三相四线中，零线的作用是：1、在三项负载不平衡的情况下，零线导通，不平衡电流流回中性点，从而使供电系统的线电压、相电压基本保持平衡；2、当采用保护接零的电气设备绝缘损坏发生碰壳时，短路电流将通过零线构成 ...
How does the three phase four line zero line connect? In three-phase four line zero line of the three-phase four wire, the zero line is 1, three in the case of load imbalance, the zero line is switched on, the unbalanced current flows back to the neutral point, so that the power supply system of the line voltage, phase voltage to maintain the basic balance; 2, when using the protective grounding insulation the damage occurred touch shell electrical equipment Zero, short-circuit current will be formed through the zero line...

插座左孔接零线右孔接火线是不是太教条了？随便接也没发生过意外呀！
Is it too dogmatic to connect the left hole of the socket to a zero line right hole wire? No accident happened at all.
插座左孔接零线右孔接火线是不是太教条了？随便接也没发生过意外呀！电气施工规范中要求，插座左孔接零线，右孔接火线。是不是太教条了，随便接也没发生过意外呀。你们说呢？ 右边为火线(L)通常用红色线表示，左边为零线(N)通常用绿色或黄色线表示，左零右火是一个电工最起码的要求。 ...
Is it too dogmatic to connect the left hole of the socket to a zero line right hole wire? No accident happened at all. In the electrical construction specification, the left hole of the socket is connected to the zero line, and the right hole is connected with the fire line. Whether it is too dogmatic and not to be accidental. What do you say? On the right, the L is usually expressed in red lines, and the left line (N) is usually expressed in green or yellow lines. The left and right fire is the minimum requirement for an electrician. ...
