1）維揚區有大量一級或二級負荷時，宜裝設二臺及以上變壓器，當其中任一臺變壓器斷開時，其余變壓器的容量能滿足一級及二級負荷的用電。一、二級負荷盡可能集中，不宜太分散。
2）維揚區季節性負荷容量較大時，宜裝設專用變壓器。如大型民用S4270D27-29維揚區27維揚區2005.7.29,3:24維揚區AM建筑中的空調冷凍機負荷、采暖用電熱負荷等。
3）維揚區集中負荷較大時，宜裝設專用變壓器。如大型加熱設備、大型X維揚區光機、電弧煉爐等。
4）維揚區當照明負荷較大或動力和照明采用共用變壓器嚴重影響照明質量及燈泡壽命時，可設照明專用變壓器。一般情況下，動力與照明共用變壓器。
根據使用環境選擇變壓器：
1）維揚區在正常介質條件下，可選用油浸式變壓器或干式變壓器，如工礦企業、農業的獨立或附建變電所、小區獨立變電所等。可供選擇的變壓器有S8、S9、S10、SC（B）9、SC（B）10維揚區等。
2）維揚區在多層或高層主體建筑內，宜選用不燃或難燃型變壓器，如SC（B）9、SC（B）10、SCZ（B）9、SCZ（B）10維揚區等。
3）維揚區在多塵或有腐蝕性氣體嚴重影響變壓器安全運行的場所，應選封閉型或密封型變壓器，如B維揚區S維揚區9、S9維揚區-維揚區、S10-維揚區、SH12-M維揚區等。
4）維揚區不帶可燃性油的高、低配電裝置和非油浸的配電變壓器，可設置在一同房間內，此時變壓器應帶IP2X保護外殼，以策安全。
根據用電負荷選擇變壓器：
1）維揚區配電變壓器的容量，應綜合各種用電設備的設施容量，求出計算負荷（一般不計消防負荷），補償后的視在容量是選擇變壓器容量和臺數的依據。一般變壓器的負荷率85%左右。此法較簡便，可作估算容量之用。
2）維(wei)(wei)揚區GB/T17468-1998《電(dian)力(li)變壓(ya)器(qi)(qi)選(xuan)(xuan)用導(dao)則(ze)》中，推(tui)薦配(pei)電(dian)變壓(ya)器(qi)(qi)的容量(liang)選(xuan)(xuan)擇，應根據(ju)GB/T17211-1998《干式電(dian)力(li)變壓(ya)器(qi)(qi)負載(zai)導(dao)則(ze)》及(ji)計算負荷(he)來(lai)確定(ding)其容量(liang)。上述二(er)導(dao)則(ze)提供(gong)了計算機程序和正常周期負載(zai)圖(tu)來(lai)確定(ding)配(pei)電(dian)變壓(ya)器(qi)(qi)容量(liang)。詳見GB/T15164-94維(wei)(wei)揚區及(ji)GB/T17211-1998維(wei)(wei)揚區有關(guan)內容

⒈開啟式.是一種常用的形式，其器身與大氣直接接觸，適應于比較干燥而潔凈的室內，（環境溫度20度時，相對濕度不應超過85%），一般有空氣自冷和風冷兩種冷卻方式.維揚區
⒉封閉式.器身處在封閉的外殼內，與大氣不直接接觸.（由于密封.散熱條件差.主要用于礦用它屬于是防爆型的）
⒊澆注式.用環氧樹脂或其它樹脂澆注作為主絕緣，它結構簡單.體積小.適用于較小容量的變壓器.
相對于油式變壓器，干式變壓器因沒有油，也就沒有火災、爆炸、污染等問題，故電氣規范、規程等均不要求干式變壓器置于單獨房間內。特別是新的系列，損耗和噪聲降到了新的水平，更為變壓器與低壓屏置于同一配電室內創造了條件。
