帶電作業接線順序，你有沒有接錯？
Are you connected to the wiring order of the live work?
正常情況下是不允許帶電作業的，但有時某場合下我們又必須帶電作業，火線，零線，地線，我們應該先接那條線呢？對于大部分電工來說這是最基本的電工知識，但對一些初學者或太過自信的老電工還是經常接錯。我們一 ...JE電機引接線JE電機引出線JE電纜
Under normal circumstances, are not allowed to live working, but sometimes some occasions we must live working, FireWire, zero line and ground, we should pick the line? For most electricians this is the most basic electrical knowledge, but some beginners or too confident old electricians often answer the wrong. We are one...

電工作業：讓人憂心的“操作票”
Electrical work: a worried "operation ticket"
作為電氣作業人員，對操作票或許不會陌生，它是倒閘操作正確性、遵守規程的證據。但是各位電工朋友，按照“操作票”操作就沒有問題嗎？本文結合一起“按票”開展的倒閘操作造成直流系統電源母線失電的真實案例，和大 ...
As an electrical operator, it may not be strange to the operation ticket. It is the proof of the correctness of the switching operation and the compliance with the regulations. But all the electrician friends, is there no problem to operate according to the "operation ticket"? In this paper, a real case of loss of power bus power bus in DC system is caused by the switching operation of "by ticket".

變壓器容量kVA與電機kW的關系JE電機引接線JE電機引出線JE電纜
The relationship between transformer capacity kVA and motor kW
變壓器容量為100-630kVA，電機功率為幾-幾百kW，kVA為視在功為，kW有功功率，kVAR為無功功率。 有功功率與無功功率平方之和等于視在功率。 他們的關系是: 有功功率=視在功率*功率因素 即P=S*cosΦ。 如一臺 ...
The capacity of the transformer is 100-630kVA, the power of the motor is several - hundreds of kW, the kVA is viewed as the work, the kW has the power of active power, and the kVAR is the reactive power. The sum of the active power and the square of the reactive power is equal to the apparent power. Their relationship is that the active power = the power * power factor is P=S*cos =. for example, a...

好貨——設計、裝配電氣控制柜的經驗之談
Absolute good design, assembly of electric control cabinet wise remark of an experienced person
我們維修電工平時設計或者裝配電氣控制柜是再普通不過的了，但是關于電氣控制柜當中的一些細節問題不知大家有無詳細總結過？今天本人根據自身工作經歷并吸收其他同行經驗融合各種理論知識，略做小結予以分享，不足之 ...
Our maintenance electricians usually design or assemble electrical control cabinets, which are more common. But I don't know if there are details about the electrical control cabinet. Today, in accordance with my own work experience and absorbing the experience of other colleagues, I amalgamated all kinds of theoretical knowledge.
