Peb-theem transformers yog cov khoom siv hluav taws xob
Peb-theem transformers yog cov khoom siv hluav taws xob tsim los hloov hluav taws xob hluav taws xob zoo hla ntau theem sib txawv hauv peb-theem systems. Cov transformers no tseem ceeb heev hauv cov ntawv thov uas xav tau kev faib hluav taws xob siab, xws li hauv kev siv hluav taws xob thiab chaw tsim khoom.
Cov lus piav qhia tseem ceeb ntawm Peb-theem Transformers:
1. Winding Configurations:Peb-theem transformers tuaj yeem teeb tsa hauv ntau qhov sib txuas sib txuas, suav nrog lub hnub qub (Y), delta (D), thiab kev sib txuas zigzag. Qhov qis-voltage winding tuaj yeem ua lag luam qhov siab-voltage winding los ntawm 30 degrees (Yd1), ua los ntawm 30 degrees (Dy11), lossis muaj lwm theem hloov ntawm 0 thiab 360 degrees, muab kev yooj yim hauv kev tsim qauv.
2. Core Hom:Lawv tuaj yeem muaj peb-limb core (core-type) lossis tsib-limb core (plhaub hom) configurations. Cov tub ntxhais ntawm peb-limb yog ib qho rau feem ntau daim ntawv thov, ua kom raug thaum lub sij hawm asymmetrical faults. Lub tsib-limb core yog xaiv tsuas yog los txo qhov siab ntawm lub transformer kom yooj yim rau kev thauj mus los thiab muaj ib tug siab natural zero-sequence inductance.
3. Kev sib koom ua ke ntawm rwb thaiv tsev:Peb-theem transformers yog tsim los nrog kev txiav txim siab rau qib rwb thaiv tsev, suav nrog Cov Txheej Txheem Txheej Txheem Txheej Txheem Txheej Txheem (BIL) thiab Hloov Rwb Thaiv Qib (SIL), uas yog qhov tseem ceeb rau kev tiv thaiv hluav taws xob thiab hloov cov impulses.
4. Cov txheej txheem tsim khoom:Cov txheej txheem tsim khoom suav nrog kev tsim kho tseem ceeb, rwb thaiv tsev, windings, core thiab coil processing, tank fabrication, thiab kev kuaj kom zoo. Cov tub ntxhais tuaj yeem muab tso ua ke siv txoj hauv kev zoo li pob tw-lap lossis kauj ruam-lap stacking, nrog rau tom kawg txo qis hauv zos flux concentration thiab ua rau qis excitation tam sim no thiab cov tub ntxhais poob.
5. Cua txias Systems:Peb-theem transformers tuaj yeem suav nrog ntau yam kev ua kom txias, xws li cov roj ducts kom tswj tau qhov kub thiab txias, thiab tuaj yeem tsim nrog ib ntus lossis ruaj khov rau kev txhawb nqa cov qauv.
6. Daim ntawv thov:Lawv tau siv dav hauv cov tshuab hluav taws xob rau kev nce lossis nce qib voltages, txuas cov tshuab hluav taws xob rau hauv daim phiaj, thiab hauv cov txheej txheem kev lag luam uas yuav tsum muaj peb-theem fais fab.
7. Kev nyab xeeb thiab kev ua haujlwm:Peb-theem transformers yog tsim los nrog kev nyab xeeb nyob rau hauv lub siab, nrog rau lub peev xwm los tiv thaiv luv luv-circuit rog thiab tswj induced voltages zoo.
8. Short-Circuit Impedance:Lub luv luv-circuit impedance ntawm cov transformers yog teev los ntawm cov neeg siv khoom thiab tuaj yeem qhia tau tias yog feem pua ntawm cov ntsuas impedance lossis nyob rau hauv cov nqe lus ntawm reactance (W) cuam tshuam rau thawj lossis theem nrab.
Hauv cov ntsiab lus, peb-theem transformers yog cov khoom siv hluav taws xob muaj peev xwm tsim tau rau kev xa hluav taws xob zoo hauv peb-theem systems. Lawv tau tsim los tiv thaiv high voltages thiab tam sim no thaum tswj kev nyab xeeb thiab kev ua haujlwm zoo, ua rau lawv tseem tsis tau muaj nyob hauv cov khoom siv hluav taws xob niaj hnub no.
