電工初學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、特性對機械設備進行自動或遠距離控制的一種方法。電氣元件根據(jù)外界的信號和要求,采用手動或自動斷開電路,斷續(xù)或連續(xù)改變電參數(shù),以實現(xiàn)電路或非電對象的切換、控制、保護、檢 ...JGG電機引接線如何區(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.

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,藍色是地線,黃綠雙色是地線。無法區(qū)分顏色時得用電筆來區(qū)分;當驗電筆亮就是火線,不亮就是零線或地線。 亮是火線 不亮是零線對于零線和地 ...JGG電機引接線如何區(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.
