指针万用表怎么测量380V交流接触器线圈
How to sure the 380V AC contactor coil by the pointer multimeter
在交流接触器带电情况时，测量电压，此时要把万用表打在交流电压的位置上（带V~的符号位置上），量程选择500V就可以量出电压值了。如果没有通电的情况下，就要测量交流接触器是否导通，这是要把万用表打到测量电阻档 ...
When the AC contactor is electrified, the voltage is sured. At this time, the multimeter should be placed on the AC voltage location (with the symbol position of V~), and the voltage range can be sured by selecting 500V. If there is no electricity, it is necessary to sure the conduction of the AC contactor, which is to beat the multimeter to the suring resistance gear.

绘制电气原理图时需遵循的规则JEM电机引接线JEM电线JEM电缆
Rules to be followed in drawing electrical schematics
绘制电气原理图时需遵循的规则电气原理图目的是便于阅读和分析控制线路，应根据结构简单、层次分明清晰的原则，采用电器元件展开形式绘制。它包括所有电器元件的导电部件和接线端子，但并不按照电器元件的实际布置位置来绘制，也不反映电器元件的 ...
The rule of electrical schematic diagram for drawing electrical schematic diagram is for easy reading and analyzing control circuit. It should be drawn according to the principle of simple structure and clear and clear hierarchy. It includes all the electrical components and terminals of the electrical components, but it doesn't draw according to the actual location of the electrical components, nor does it reflect the electrical components.

开关变压器工作原理
Working principle of switch transformer
开关变压器工作原理 对于开关电源，开关变压器的工作原理与普通变压器的工作原理是不同的。普通变压器输入的交流电压或电流的正、负半周波形都是对称的，并且输入电压和电流波形一般都是连续的，在一个周期之内，输入电压和电流的平 ...
The working principle of the switching transformer is different from the operating principle of the switching transformer and the working principle of the common transformer. The positive and negative half cycle waveform of AC voltage or current input in common transformers is symmetrical, and the input voltage and current waveforms are generally continuous. In a cycle, the input voltage and current level are flat.
