Kais changers yog cov khoom siv uas tuaj yeem nce lossis txo qhov tso zis theem nrab voltage los ntawm kev hloov pauv hloov pauv ntawm thawj lossis theem nrab winding. Lub kais hloov pauv feem ntau yog ntsia rau ntawm qhov hluav taws xob siab ntawm ob-winding transformer, vim qhov tam sim no tsis tshua muaj nyob rau hauv cheeb tsam ntawd. Cov kev hloov pauv kuj tau muab rau ntawm qhov hluav taws xob siab windings ntawm cov hluav taws xob hloov hluav taws xob yog tias muaj kev tswj kom txaus ntawm qhov hluav taws xob. Qhov kev hloov ntawm qhov voltage yog cuam tshuam thaum koj hloov tus naj npawb ntawm lem ntawm lub transformer muab nrog kais.
Muaj ob hom Tap Changers:
1. On-Load Kais Changer
Nws lub ntsiab feature yog thaum lub sij hawm ua hauj lwm, lub ntsiab Circuit Court ntawm lub hloov yuav tsum tsis txhob qhib. Qhov no txhais tau hais tias tsis muaj ib feem ntawm qhov hloov yuav tsum tau txais luv luv Circuit Court. Vim qhov kev nthuav dav thiab kev sib txuas ntawm lub zog hluav taws xob, nws yog ib qho tseem ceeb rau kev hloov pauv cov kais dej ntau zaus txhua hnub kom ua tiav qhov tsim nyog voltage raws li qhov xav tau ntawm kev thauj khoom.
Qhov kev thov ntawm cov khoom siv tas mus li no tsis tso cai rau koj los txiav tawm lub tshuab hluav taws xob los ntawm lub kaw lus rau kev hloov pauv hloov pauv. Li no, on-load kais hloov pauv yog nyiam nyob rau hauv feem ntau ntawm lub hwj chim transformers.
Ob qho xwm txheej yuav tsum tau ua tiav thaum tapping:
· Lub load Circuit Court yuav tsum zoo kom tsis txhob arcing thiab tiv thaiv kev puas tsuaj
· Thaum kho tus kais dej, tsis muaj ib feem ntawm cov windings yuav tsum luv luv
Hauv daim duab saum toj no, S yog qhov hloov pauv hloov pauv, thiab 1, 2 thiab 3 yog qhov hloov pauv. Tus kais hloov pauv siv lub chaw tapped reactor R raws li qhia hauv daim duab. Lub transformer ua haujlwm thaum lub keyboards 1 thiab S raug kaw.
Txhawm rau hloov mus rau kais 2, hloov S yuav tsum qhib thiab hloov 2 yuav tsum raug kaw. Txhawm rau ua kom tiav qhov hloov pauv, hloov 1 yog ua haujlwm thiab hloov S raug kaw. Nco ntsoov tias qhov hloov pauv hloov pauv ua haujlwm ntawm-load thiab tsis muaj qhov ntws tam sim no hauv cov keyboards xaiv thaum hloov pauv. Thaum koj coj mus rhaub hloov, tsuas yog ib nrab ntawm cov reactance uas txwv qhov tam sim no txuas rau hauv Circuit Court.
2.Off-Load/No-load Kais Changer
Koj yuav tsum nruab ib qho kev hloov pauv ntawm qhov hloov pauv yog tias qhov yuav tsum tau hloov pauv hauv qhov tsis tshua muaj zog. Cov kais dej tuaj yeem hloov pauv tau tom qab cais tag nrho lub tshuab hloov pauv ntawm lub voj voog. Hom kev hloov pauv no feem ntau yog ntsia rau ntawm lub tshuab hluav taws xob faib khoom.
Cov kais hloov pauv tuaj yeem nqa tawm thaum lub tshuab hloov pauv nyob rau hauv Off-Load lossis Tsis Muaj-Load. Nyob rau hauv ib tug qhuav-hom transformer, qhov txias tshwm sim tshwm sim feem ntau nrog ntuj huab cua. Tsis zoo li hauv on-load kais hloov qhov twg arc quenching yog txwv los ntawm cov roj thaum lub transformer yog on-load, tapping nrog ib tug off-load kais changer tsuas yog nqa tawm thaum lub transformer nyob rau hauv OFF-Switch mob.
Nws yog feem ntau siv nyob rau hauv cov xwm txheej uas tig-piv txwv tsis tas yuav hloov pauv ntau, thiab de-energizing raug tso cai nyob rau hauv qis zog thiab tsawg voltage transformers. Hauv qee qhov, kais hloov pauv tuaj yeem ua tiav nrog lub tshuab hloov pauv lossis hloov pauv. Nws tuaj yeem pom tsuas yog hauv cov phiaj xwm hnub ci fais fab.
Off-load kais hloov pauv kuj tseem siv nyob rau hauv high voltage transformers. Lub kaw lus ntawm xws li transformers muaj xws li ib tug tsis muaj-load kais changer ntawm thawj winding. Qhov kev hloov pauv no pab ua kom haum rau cov kev hloov pauv hauv qhov nqaim ntawm ib ncig ntawm qhov ntsuas nominal. Hauv cov tshuab zoo li no, kev hloov pauv kais feem ntau yuav ua tiav ib zaug xwb, thaum lub sijhawm teeb tsa. Txawm li cas los xij, nws tseem tuaj yeem hloov pauv thaum lub sijhawm teem sijhawm los daws qhov kev hloov mus sij hawm ntev hauv qhov system qhov voltage profile.
Nws yog ib qho tseem ceeb uas koj xaiv qhov zoo ntawm tus kais hloov pauv raws li koj xav tau.
