1.4 Lub Zog Efficiency Advantages
DOE-Compliant Low- Loss Design
Lub transformer ua tau raws li DOE efficiency, uas txhais tau tias nws tsis muaj -load poob ntawm 2.4 kW thiab load poob ntawm 15.79 kW nyob twj ywm tsis tu ncua. Txawm hais tias cov lej no zoo li me me nyob rau hauv kev sib cais, lawv sib sau ua ke mus ntev - lub zog txuag hluav taws xob uas tsis tu ncua txo cov nqi khiav lag luam thiab ib puag ncig lub nra rau ntau xyoo ntawm kev ua haujlwm tsis tu ncua.
Optimized Sib Nqus Circuit Court - Tsib-Kem Core
Lub tsib-Kem core tsim ib txoj kev sib nqus smoother, txo cov flux ceev, suppressing harmonics, thiab txo cov keeb kwm yav dhau hum uas transformers feem ntau tsim. Nws kuj yog ib txwm txiav txim siab rau qhov kev poob qis, tso cai rau tag nrho cov kab ke ua haujlwm tau zoo dua thiab nrog kev ruaj ntseg nyob ntsiag to uas xav tias txhob txwm tshaj tawm tsis yog qhov xwm txheej.
ONAN ntuj txias
Nws ONAN lub tshuab cua txias yog nyob ntawm huab cua puag ncig- tsis muaj kiv cua, tsis muaj lub cev muaj zog, tsis muaj dab tsi ntxiv dag zog ntxiv- yog li lub tshuab hloov pauv txias nws tus kheej nrog yuav luag tsis yooj yim, siv cov huab cua nyob ib puag ncig los tswj qhov kub thiab txias thaum tsis txhob siv lub zog siv hluav taws xob, txo suab nrov, thiab txo qis dua - lub sij hawm txij nkawm xav tau.
02 Kev tsim khoom
2.1 Core
Kev siv peb -theem tsib-Kum core ua kom cov khoom sib nqus sib nqus sib nqus sib nqus rau txhua theem, ua tiav cov hlau nplaum sib txuas zoo heev. Qhov kev tsim no tsis tsuas yog txo qis cov hlau nplaum sib nqus tab sis kuj ua kom zoo dua lub zog hloov pauv ntawm lub tshuab hluav taws xob, yog li txhim kho kev ua haujlwm tag nrho. Lub tsib-kem tsim muaj txiaj ntsig zoo tiv thaiv kev sib raug zoo, txo cov suab nrov, thiab txo qis thermal poob, ua kom muaj kev ntseeg siab thiab kev nyab xeeb nyob rau hauv ntau yam kev thauj khoom.
Tsis tas li ntawd, Y-Y kev sib txuas nrog peb -theem tsib-Kem core txhawb nruab nrab point grounding, uas txhim kho kev tuav cov khoom tsis sib npaug thiab luv luv - Circuit Court faults.
2.2 Lub Rooj Sib Tham Kawg
1. Hoisting qhov Active Part rau hauv cov roj Tank:Hoist lub active feem ntawm lub transformer (core thiab windings) thiab muab tso rau hauv lub tank roj.
2. Kev sib txuas hluav taws xob:Txuas cov windings mus rau bushings, ua kom muaj kev ruaj ntseg thiab zoo - insulated kev sib txuas.
3. Accessory Installation:Nruab cov khoom siv, suav nrog peb lub ntsuas thiab ib lub valve, nrog rau lwm yam khoom siv.
4. Sealing Cov Roj Tank:Kaw lub tank roj thiab sau nws nrog roj transformer rau rwb thaiv tsev thiab cua txias.
03 Environmental Feature
Stainless hlau Tank - Lub neej ntev, Tsawg pov tseg
Lub tank stainless hlau tiv thaiv corrosion, tiv taus qhov hnyav sab nraum zoov, ncua kev pab cuam lub neej dhau tus qauv hlau, txo cov kev hloov pauv thiab pov tseg, thiab tseem rov ua dua tshiab.
Internal Fault Detector (IFD)
IFD saib xyuas cov kev hloov pauv sab hauv thiab ceeb toom ntxov, tiv thaiv kev xau, khoom siv puas tsuaj, thiab kev pheej hmoo ib puag ncig ua ntej lawv nce ntxiv.
Aluminium Windings - Sib zog Carbon Footprint
Aluminium windings siv tsawg zog los tsim ntau dua tooj liab, dissipate tshav kub zoo, txo cov pa roj carbon hneev taw, thiab txhawb nqa ntev - lub sij hawm transformer efficiency.
