Dab tsi yog 11kV peb -theem roj immersed transformer?

Peb-theem roj immersed transformer yog lub hwj chim transformer uas yog txias thiab insulated los ntawm insulating roj. Nws yog tsim los siv nyob rau hauv peb-theem AC lub zog hluav taws xob thiab tuaj yeem hloov hluav taws xob hluav taws xob siab rau hauv qhov hluav taws xob qis (xws li 11kV / 400V). Nws yog dav siv hauv kev lag luam, kev lag luam, thiab hluav taws xob faib hluav taws xob.

 

Dab tsi yog cov xwm txheej ntawm daim ntawv thov?

* Kev hloov pauv hluav taws xob hauv nroog faib hluav taws xob (11kV → 400V);

* Kev faib hluav taws xob hauv cov nroj tsuag muaj xws li mines thiab petrochemicals;

* Daim phiaj kev sib txuas ntawm cov chaw tsim hluav taws xob tauj dua tshiab (xws li cua ua liaj ua teb);

* Cov tsev kho mob, cov chaw khaws ntaub ntawv, thiab lwm qhov chaw uas xav tau cov khoom siv hluav taws xob muaj kev ntseeg siab.

 

Qhov ntsuas muaj peev xwm yog dab tsi?

Lub peev xwm ntau ntawm 25kVA txog 10MVA, nrog rau 100kVA txog 2000kVA qauv ntawm 11kV / 400V yog qhov siv dav tshaj plaws, nyob ntawm qhov yuav tsum tau ua.

 

Dab tsi yog qhov sib txawv ntawm kev saib xyuas lub voj voog ntawm 11kV qhuav- hom thiab roj rau hauv cov tshuab hloov pauv?

Hom Qhuav: Kev tshuaj xyuas cov plua plav tshem tawm txhua 2-3 xyoos; Roj immersed: Xyuas cov roj theem, roj zoo (siab tsis kam nqi, acidity), sealing, thiab radiator tu ib xyoos ib zaug; Kev ntsuas cov roj ntsuas txhua txhua 3-5 xyoos (xws li qhov poob qis thiab cov ntsiab lus noo noo).

 

Yuav ua li cas xaiv ntawm peb -theem roj immersed transformer thiab qhuav-hom transformer?

-11kV roj immersed transformers yog tsim rau sab nraum zoov, muaj peev xwm, thiab siab load scenarios, nrog rau tus nqi qis tab sis yuav tsum tau kev saib xyuas tsis tu ncua;

-11kV qhuav-hom transformer: siv nyob rau hauv ib puag ncig sab hauv tsev uas yuav tsum muaj kev tiv thaiv hluav taws kub (xws li khw malls thiab subways), txij nkawm dawb tab sis kim.

 

Yuav ua li cas txiav txim seb lub transformer yuav tsum tau hloov roj los yog lim roj?

-Kev ntsuas roj zoo: Tsis tu ncua ntsuas qhov hluav taws xob tawg (yuav tsum siab dua lossis sib npaug li 30kV), cov dej ntsiab lus (tsawg dua lossis sib npaug li 20ppm), thiab cov kua qaub ntawm cov roj;

- Cov roj xim huab cua: Cov roj yuav tsaus dua lossis muaj qhov nce ntxiv ntawm cov teeb meem tshem tawm;

-Kev rwb thaiv tsev tsis zoo: txiav txim siab los ntawm kev ntsuas hluav taws xob tiv thaiv.

 

 

Dab tsi yog vim li cas rau qhov txawv txavkub ncethaum ua haujlwm?

-Lub sij hawm ntev overload;

-Cov cua txias ua haujlwm tsis zoo ( kiv cua / roj twj tso kua mis);

-Oil circuit blockage lossis roj ntim tsis txaus;

-Internal luv Circuit Court lossis kev sib cuag tsis zoo.

 

Yuav ua li cas daws cov roj to hauv cov roj immersed transformers?

- Cov roj to me me: nruj bolts lossis hloov gaskets;

- Cov roj xau loj: nres tam sim ntawd, tshem cov roj thiab kho lossis hloov cov khoom siv;

 

Cov cuab yeej tiv thaiv dab tsi yuav tsum tau teeb tsa?

* High voltage sab: Circuit Court breaker los yog fuse (nrog overcurrent/short-circuit tiv thaiv);

* Kev tiv thaiv lub cev: roj relay, siab nyem valve, roj ntsuas kub;

* Kev tiv thaiv kab ke: xob laim ntes (anti xob laim impulse)

* Cov cuab yeej saib xyuas: roj qib ntsuas, cov roj chromatography hauv online (high-}kawg configuration).

 

 

Dab tsi yog cov ntsiab lus tseem ceeb uas yuav tsum tau saib xyuas thaum txhim kho?

-Lub hauv paus ruaj khov, kev teeb tsa kab rov tav, tsis txhob tilting;

-Thov kom txaus qhov chaw tso cua sov (xws li tsawg kawg 1.5 meters deb ntawm phab ntsa);

-Grounding resistance Tsawg dua lossis sib npaug rau 4 Ω;

-Kuaj xyuas cov roj qib, kev sib khi, thiab kev huv ntawm lub hau.
