The Challenge:
Environmental Safety & Security
Environmental protection demands are today
constantly rising. Ever more frequently, dry type
transformers user specifications are focused on
creating minimum environmental contamina-
tion and providing the very lowest flammabili-
ty risks. For this reason, our transformers must
today constantly meet more stringent parameters
with respect to electrical system demands, as
well as more extreme operating conditions. Glass fibre reinforcement
Applications today include: high-rise office and eliminates all risk of cracks
public buildings, nuclear power plants, offshore and provides the highest
petrochemical platforms, and high output mechanical strength
industrial process plants.
Development of many new technologies has
enabled our transformer designers to apply
modern materials with the very latest of pro-
cesses, increasing the transformers durability
while ensuring unprecedented product reliability.
Thermal shock proof
If any of the following demands form part of even at the highest and
your transformer application, then ABB has the lowest temperatures
necessary solution:
No environmental or human
contamination risks
Non-explosive and extreme fire resistance
Heavy loading cycles (from cold starts to
full loading)
High short circuit withstand Smooth surfaces restrict
Exposure to extreme conditions (arctic, dust accumulation
tropic, chemicals, moistures etc)
Harmonic overloading, over-voltage peaks
or variable load factors
Minimum maintenance

ABB作為全球知名的電力和自動(dòng)化技術(shù)供應(yīng)商，其落地式干式變壓器是一種廣泛應(yīng)用在各種工業(yè)與民用領(lǐng)域的高效、環(huán)保的電力設(shè)備。這種變壓器采用干式冷卻方式，具有以下特點(diǎn)： 1. 結(jié)構(gòu)緊湊：由于是落地安裝設(shè)計(jì)，占用空間相對(duì)較小，便于在有限的空間內(nèi)靈活部署，特別適合于工廠、數(shù)據(jù)中心、商業(yè)建筑等對(duì)空間利用率要求高的場(chǎng)所。 2. 無(wú)油結(jié)構(gòu)：干式變壓器沒(méi)有傳統(tǒng)油浸變壓器使用的絕緣油，避免了火災(zāi)風(fēng)險(xiǎn)以及維護(hù)過(guò)程中可能產(chǎn)生的環(huán)境污染問(wèn)題，符合現(xiàn)代綠色環(huán)保的發(fā)展趨勢(shì)。 3. 高可靠性：干式變壓器具有良好的散熱性能，能夠在各種氣候條件下穩(wěn)定運(yùn)行，同時(shí)內(nèi)部繞組和鐵芯均采用高質(zhì)量材料制造，確保長(zhǎng)期運(yùn)行中的高效率和低損耗。 4. 維護(hù)便捷：由于采用免維護(hù)或少維護(hù)的設(shè)計(jì)，使得日常維護(hù)工作量大大減少，僅需定期檢查和更換一些易損件，如空氣過(guò)濾器、冷卻風(fēng)扇等。 5. 安全性強(qiáng)：具備多重安全保障措施，如過(guò)載保護(hù)、短路保護(hù)、溫度監(jiān)控及報(bào)警系統(tǒng)等，能有效防止因過(guò)熱或其他異常情況導(dǎo)致的故障。 總之，ABB落地式干式變壓器憑借其卓越的技術(shù)性能、優(yōu)良的安全性和節(jié)能環(huán)保特性，在電力行業(yè)中得到了廣泛的應(yīng)用和認(rèn)可。
