Nkaum Losses ntawm Distribution Transformers: Ib Qhov Muaj Peev Xwm "Black Hole rau Cov Nqi Hluav Taws Xob"

Nyob rau hauv tag nrho cov nqi khiav hauj lwm ntawm factories, industrial parks, thiab infrastructure tej yaam num, cov nqi hluav taws xob feem ntau yog qhov thib peb - kev siv nyiaj loj tshaj plaws, thib ob tsuas yog cov khoom siv raw thiab tib neeg. Thaum peb tau mob siab rau kev txhim kho cov kab ntau lawm thiab ua kom muaj zog txuag hluav taws xob hauv kev tswj hwm, peb puas tau saib xyuas tus nqi zais uas tsis tu ncua erodes profits - faib transformers?

 

Lawv tsis yog tsuas yog lub hauv paus ntawm cov khoom siv hluav taws xob xwb tab sis kuj yog qhov chaw tsis pom kev hauv kev tswj hwm tus nqi. Optimizing lawv lub zog efficiency txhais tau tias seizing tangible profits.

 

 

Transformer poob ntau tshaj qhov yooj yim "standby zog noj"; lawv sawv cev rau qhov teeb meem kev siv hluav taws xob zoo uas cuam tshuam ncaj qha rau kev lag luam kev ua haujlwm nyiaj txiag.

 

1. Tsis muaj-Load Poob (hlau poob)

Tsis muaj-load poob yog hais txog kev siv hluav taws xob ruaj khov uas tshwm sim thaum lub tshuab hluav taws xob txuas nrog lub zog hluav taws xob-txawm tias nws qhov chaw nruab nrab tsis thauj khoom- kom tswj tau qhov chaw sib nqus sab hauv (excitation).

 

Qhov kev poob no feem ntau yog hysteresis poob thiab eddy tam sim no poob:

• Hysteresis poob: tshwm sim los ntawm lub zog dissipation tshwm sim los ntawm kev sib txhuam ntawm cov hlau nplaum nyob rau hauv cov tub ntxhais hlau thaum nws rov qab magnetized thiab demagnetized nyob rau hauv alternating magnetic teb.
• Eddy tam sim no poob: tshwm sim thaum ib qho chaw sib nqus sib nqus induces ncig tam sim no (eddy currents) nyob rau hauv cov tub ntxhais hlau, ua rau thermal zog poob.

 

Tus yam ntxwv tseem ceeb ntawm tsis muaj -load poob yog tias nws yog ib qho kev poob, tas li. Nws tseem nyob ntev npaum li lub transformer txuas nrog rau daim phiaj fais fab, thiab nws qhov loj yog txiav txim siab los ntawm cov khoom siv tseem ceeb thiab cov txheej txheem tsim khoom thaum lub transformer tsim thiab tsim. Rau qhov qub los yog tsis muaj peev xwm hloov pauv, cov nqi hluav taws xob uas tshwm sim los ntawm qhov tsis muaj - load poob yog ntshiab, ntev - cov nqi khiav lag luam ruaj khov -zoo ib yam li kev lag luam "basal metabolic" cov nqi- thiab yuav tsum yog qhov tseem ceeb tshaj plaws hauv lub zog- txuag kev kho dua tshiab.

 

2. Load Poob (Copper Poob)

Load poob yog qhov sib txawv ntawm qhov poob uas tshwm sim thaum lub tshuab hluav taws xob ua haujlwm nyob rau hauv load: tam sim no ntws los ntawm qhov siab - thiab qis -voltage windings, generating tshav kub vim qhov inherent tsis kam ntawm cov conductors. Nws kuj suav nrog kev poob qis uas tshwm sim los ntawm cov hlau nplaum sib nqus hauv cov khoom siv.

 

Nws cov yam ntxwv tseem ceeb yog tias nws yog proportional rau lub square ntawm lub load tam sim no (P ∝ I²). Qhov no txhais tau tias yog tias lub load tam sim no doubles, qhov poob yuav plaub npaug. Tsis tas li ntawd, tus neeg xyuas pib kuj nce nrog qhov kub thiab txias - nyob rau hauv tib lub load, siab dua kev khiav hauj lwm kub ntawm lub transformer yuav ua rau kom poob load ntau dua. Yog li ntawd, load poob yog ib tug ncaj derivative nqi ntawm ib tug enterprise cov kev ua ub no: lub busier ntau lawm, tus nqi hluav taws xob ntau dua los ntawm qhov poob.

 

Kev khiav hauj lwm efficiency ntawm ib tug transformer yog ze ze rau nws load yam. Kev khiav hauj lwm rau lub sij hawm ntev nyob rau hauv lub xeev ntawm "cov khoom siv loj tshaj rau cov khoom siv qis" (tsis tshua muaj load) los yog ze rau - txwv kev thauj khoom siab yuav ua rau nws txoj kev ua haujlwm zoo nyob deb ntawm qhov kev lag luam zoo tshaj plaws, uas ua rau lub zog loj.

 

(Faj seeb: Raws li qhov loj thiab tsim qauv, aluminium-core transformers ua rau poob siab dua tooj liab-core transformers.

 

Ib tsab xov xwm cais ntawm peb piav qhia qhov sib piv ntawm ob:

3. Tus nqi zais

Kev poob siab feem ntau yog nrog los ntawm kev tsim hluav taws xob ntau dhau, uas ua rau kev laus ntawm cov ntaub ntawv rwb thaiv tsev thiab ua rau muaj kev pheej hmoo ntawm downtime. Qhov kev poob los ntawm kev poob qis yog ntau dua li qhov pov tseg ntawm lub zog nws tus kheej. Nyob rau tib lub sijhawm, cov cua kub ntau dhau kuj ua rau muaj kev siv zog ntxiv ntawm cov cua txias thiab ua rau muaj kev tu ncua ntau zaus.

 

Piv txwv

Siv 1000kVA roj-immersed peb-theem transformer nrog qhov ntsuas hluav taws xob ntawm 10kV ua piv txwv (cov khoom siv tseem ceeb: silicon steel los xij):

 

 

Tus lej poob tag nrho: P=P₀ + Pₖ × ²

 

(qhov twg yog qhov khoom thauj khoom, noj qhov nruab nrab kev lag luam tus nqi ntawm 60%, piv txwv li,=0.6)

• Class 2 zog efficiency: P₂=745 + 8240 × 0.6²=3711.4 W
• Class 3 zog efficiency: P₃=830 + 10300 × 0.6²=4538 W

Rau kev ua haujlwm tas mus li txhua xyoo (8760 teev), kev txuag hluav taws xob txhua xyoo ntawm Chav Kawm 2 lub zog siv hluav taws xob piv rau Chav Kawm 3 ib qho yog:

• ΔWₙᵧₑₐᵣ (Kev txuag hluav taws xob ib xyoos ib zaug)=(P₃ - P₂) × 8760=7241 kWh
