電氣設備安裝調試技術分析
Technical analysis of installation and debugging of electrical equipment
在安裝開始前要注意以下問題：變壓器安裝要做好絕緣檢查，注意選擇合理的安裝工具，確認變壓器安裝的位置和方式。在進行電氣設備安裝調試過程中，安裝人員要結合電氣設備的性能，制定好設備安裝調試工序，控制好每一 ...
Before installing, we should pay attention to the following problems: insulation inspection should be done for transformer installation, attention should be paid to selecting reasonable installation tools, confirming the location and mode of transformer installation. In the process of installation and commissioning of electrical equipment, the installation personnel should combine the performance of electrical equipment, set up a good equipment installation and commissioning process, control each of them well.

零火線都帶電什么原因?怎么處理?JEM電機引接線電氣二次電路圖中的電壓回路編號方法
What's the reason for the line of zero fire line and how to deal with it?
零火線都帶電什么原因?怎么處理?具體情況不好說，但從經驗來看一種是偏相了造成零線帶電，這種情況在電網中不可避免，零線帶的電壓也不會太高，只要不是偏相偏的太離譜不影響正常使用。還有一種是斷了零線就比較麻煩了，以我們普通的樓房例子，一種 ...
The zero line are charged for what reason? How to deal with the specific circumstances? Not to say, but from experience is a partial phase caused by the zero line charged, this power is inevitable, with the zero line voltage is not too high, as long as not too outrageous offset does not affect the normal use. Another kind is the trouble of breaking the zero line, with the example of our ordinary building, one kind of..
