Vim li cas Distribution Transformer Txuas Hauv Delta Star
Fais fab mov transformers yog cov khoom tseem ceeb hauv kev xa hluav taws xob thiab kev faib khoom. Lawv yog lub luag haujlwm rau kev nqis qis qis ntawm qhov hluav taws xob siab ntawm sab kis mus rau qhov tsis tshua muaj hluav taws xob uas tsim nyog rau kev muab hluav taws xob rau tsev neeg thiab kev lag luam. Feem ntau, cov khoom siv hluav taws xob xa hluav taws xob txuas nrog hauv delta-star configuration vim muaj ntau yam laj thawj.
Ib qho ntawm cov laj thawj tseem ceeb vim li cas cov khoom siv hluav taws xob faib hluav taws xob txuas nrog hauv delta-star configuration yog los txhim kho kev ua haujlwm ntawm lub cev. Delta winding muaj kev ua haujlwm siab dua thaum piv rau lub hnub qub winding, uas ua rau nws yog qhov kev xaiv zoo tshaj plaws rau sab hluav taws xob siab ntawm transformer. Lub delta winding yog tsim nyob rau hauv xws li ib txoj kev uas nws muaj peev xwm lis ib tug ntau dua tam sim no thaum txo qhov voltage poob nyob rau hauv lub winding.
Lwm qhov laj thawj vim li cas cov khoom siv hluav taws xob xa hluav taws xob txuas nrog hauv delta-star configuration yog muab kev tiv thaiv zoo dua tiv thaiv dhau-voltage. Lub delta winding nyob rau sab high voltage ntawm lub transformer muab ib tug zoo tsis zoo tiv thaiv over-voltage tej yam kev mob, uas yuav tshwm sim los ntawm xob laim, switching surges, los yog lwm yam teeb meem nyob rau hauv lub system. Qhov no pab tiv thaiv lub transformer los ntawm kev puas tsuaj thiab xyuas kom meej tias lub kaw lus tseem ua haujlwm txawm tias thaum muaj xwm txheej tsis zoo.
Tsis tas li ntawd, kev sib txuas cov transformers hauv delta-star configuration kuj muab kev tiv thaiv zoo dua. Lub delta winding muab ib txoj hauv kev rau av faults uas tshwm sim nyob rau hauv high voltage sab ntawm lub transformer. Qhov no yuav pab txo qhov kev pheej hmoo ntawm kev puas tsuaj rau lub transformer thiab lwm yam khoom hauv lub cev. Tsis tas li ntawd, lub hnub qub winding nyob rau sab qis voltage ntawm lub transformer muab ib qho nruab nrab taw tes uas tso cai rau kev tiv thaiv zoo hauv av.
Hauv cov ntsiab lus, kev sib txuas cov khoom siv hluav taws xob sib txuas hauv delta-star configuration pab txhim kho kev ua haujlwm ntawm lub cev, muab kev tiv thaiv zoo dua tiv thaiv dhau-voltage thiab txo qhov kev pheej hmoo ntawm kev puas tsuaj vim kev ua txhaum hauv av. Qhov no yog vim li cas qhov kev teeb tsa no feem ntau siv hauv kev xa hluav taws xob thiab kev faib hluav taws xob.
