Ib kauj ruam-nce transformer yog hom transformer uas hloov qhov hluav taws xob qis (LV) thiab siab tam sim no los ntawm thawj sab ntawm transformer mus rau high voltage (HV) thiab tsis tshua muaj nqi tam sim no nyob rau theem nrab ntawm lub transformer. Qhov thim rov qab ntawm qhov no yog hu ua kauj ruam down transformer.
Lub hom phiaj ntawm kauj ruam transformer yog dab tsi?
Ib kauj ruam nce transformer ntawm fais fab chaw nres tsheb nce qhov hluav taws xob thiab thiaj li nqis qis tam sim no. Qhov no txhais tau hais tias tam sim no ntws nyob rau hauv cov nyiaj siv ua haujlwm cables kuj yog me me thiab tuaj yeem faib tau mus deb thoob plaws lub tebchaws.
kauj ruam nce thiab nqis nqis transformer ua haujlwm li cas?
Ib lub tshuab hloov pauv hloov tam sim no (AC) los ntawm ib qho hluav taws xob mus rau lwm qhov hluav taws xob. Nws tsis muaj qhov txav txav thiab ua haujlwm ntawm lub hauv paus ntsiab lus sib nqus induction; nws tuaj yeem tsim los rau "step-up" lossis "step-down" voltage. Yog li nce qib transformer nce qhov voltage thiab theem qis transformer txo qhov voltage
Ntau npaum li cas voltage tuaj yeem nce qib transformer nce?
Txij thaum lub kauj ruam-up transformer nce voltage thiab txo tam sim no; ces, 50 V AC qhov yuav tsum muab LESSER CURRENT tshaj li 10 V (raws li kev txuag hluav taws xob). Tag nrho cov transformers muaj ob qho tib si thawj thiab theem nrab kauj.
Yuav ua li cas hloov pauv ntawm transformer?
Tus lem ratio ntawm ib tug transformer yog txhais raws li tus naj npawb ntawm lem ntawm nws theem nrab muab faib los ntawm tus naj npawb ntawm lem ntawm nws thawj.

Lub pob zeb nyob rau theem twg?
Lub Pob Zeb Hauv Chaw Ua Si yog qhov kev lom zem sab nraum zoov pub dawb nyob rau hauv Hyde Park rau 5 Lub Xya Hli 1969, tau hais los ntawm Rolling Stones thiab featuring Third Ear Band, King Crimson, Screw, Alexis Korner lub Koom Txoos Tshiab, Tsev Neeg thiab Cov Khoom Siv Hluav Taws Xob, nyob rau pem hauv ntej ntawm cov neeg tuaj saib kwv yees li ntawm 250,000–500,000 tus neeg saib .
Nyob rau hauv mosses theem nrab protonema tshwm sim los ntawm?
Cov lus piav qhia ntawm protonemata feem ntau pom muaj nyob hauv txhua qhov muaj mosses thiab qee qhov ntawm lub cev. … Primary protonema yog ib feem tseem ceeb ntawm cov saw no uas yog tsim los ntawm ib tug spore. Secondary protonema tsim los ntawm ib feem ntawm cov neeg laus uas muaj xws li stems, nplooj thiab rhizoids Yuav ua li cas theem nrab protonema tsim?
Nyob rau theem hyperpolarization?
Hyperpolarization yog ib theem uas qee cov poov tshuaj nyob twj ywm qhib thiab sodium channels rov pib duaIb lub sijhawm ntawm cov poov tshuaj permeability nce ntxiv ua rau cov poov tshuaj ntau dhau ua ntej cov kab poov tshuaj kaw. Qhov no ua rau hyperpolarization raws li pom hauv me ntsis poob tom qab qhov nce .
Nyob rau hauv teb rau qhov tuaj txog ntawm acidic chyme nyob rau hauv lub duodenum?
Pab plab hnyuv . theem plab hnyuvtshwm sim hauv duodenum raws li cov lus teb rau cov chyme tuaj txog, thiab nws txo qis kev ua pa ntawm plab los ntawm cov tshuaj hormones thiab lub paj hlwb reflexes . Yuav ua li cas teb rau qhov tuaj txog ntawm acidic chyme hauv duodenum?
Nyob ntawm substation lub transformer voltage yog qis dua rau?
Transformers txo qis qhov sib kis tau zoo heev rau hauv voltage tsawg dua 10 000 volts, uas yog tsim rau kev faib khoom . Dab tsi yog cov kauj ruam-down voltages ntawm substation? Lub kauj ruam-down substation tuaj yeem hloov pauv qhov hluav taws xob xa mus rau qhov hluav taws xob subtransmission, feem ntau 69 kV.
