電工初學(xué)者如何快速看懂電氣控制電路圖

How the electrician beginners understand the electrical control circuit quickly

電工初學(xué)者如何快速看懂電氣控制電路圖電氣控制是借助于各種電器元件的結(jié)構(gòu)、特性對(duì)機(jī)械設(shè)備進(jìn)行自動(dòng)或遠(yuǎn)距離控制的一種方法。電氣元件根據(jù)外界的信號(hào)和要求，采用手動(dòng)或自動(dòng)斷開電路，斷續(xù)或連續(xù)改變電參數(shù)，以實(shí)現(xiàn)電路或非電對(duì)象的切換、控制、保護(hù)、檢 ...JGG電機(jī)引接線如何區(qū)分和判斷火線零線地線

How to quickly understand the electrical control circuit diagram of electrical beginners? Electrical control is a way to control the mechanical equipment automatically or remotely by means of the structure and characteristics of various electrical components. According to the external signals and requirements, the electric components are manually or automatically disconnected, changing the electrical parameters intermittently or continuously, so as to realize the switch, control, protection and inspection of circuits or non electric objects.

電氣接線圖講解

Explanation of electrical wiring diagram

電氣接線圖講解接線圖是根據(jù)電路原理圖繪制的，應(yīng)按照原理圖來看。下圖為接線圖實(shí)例。 先看主電路，再看控制電路。看接線圖要根據(jù)端子標(biāo)志、回路標(biāo)號(hào)，從電源端順序查下去，搞清楚電路的走向和電路的連接方法，及搞清楚每個(gè)元器件 ...

Electrical wiring diagram explanation wiring diagram is based on the circuit schematic drawing, should be in accordance with the principle of view. The following diagram is an example of the wiring diagram. First look at the main circuit, and then look at the control circuit. The wiring diagram should be checked down from the terminal of the power supply according to the terminal mark and loop label, and we should make clear the way of the circuit and the connection method of the circuit, and figure out every component.

如何區(qū)分和判斷火線零線地線

How to distinguish and judge the zero line ground wire of fire line

如何區(qū)分和判斷火線零線地線在家里一般我們可以用顏色來區(qū)分，正常情況下黃色綠色紅色三種顏色是火線，藍(lán)色是地線，黃綠雙色是地線。無法區(qū)分顏色時(shí)得用電筆來區(qū)分；當(dāng)驗(yàn)電筆亮就是火線，不亮就是零線或地線。 亮是火線 不亮是零線對(duì)于零線和地 ...JGG電機(jī)引接線如何區(qū)分和判斷火線零線地線

How to distinguish and judge the zero line ground wire at home can be distinguished by color. Under normal circumstances, yellow, green and red are the three kinds of fire lines, the blue is the ground wire, and the yellow green double color is the ground wire. Cannot distinguish between colors when using pencil to distinguish; when the test pencil light is not bright is FireWire, zero line or wire. The light is that the fire line is not bright, the zero line is to the zero line and the ground.
