Ntiaj teb Transformers

Lub ntiaj teb transformer, tseem hu ua grounding transformer, yog ib hom transformer uas yog siv los tsim kev tiv thaiv lub ntiaj teb kev twb kev txuas rau hluav taws xob systems. Nws muaj ib qho hluav taws xob winding uas txuas nrog lub ntiaj teb thiab tsim los tsim kom muaj qhov nruab nrab nruab nrab uas yog hauv av.

Earthing transformers ua lub luag haujlwm tseem ceeb hauv kev nyab xeeb hluav taws xob. Lawv yog siv los txo cov kev pheej hmoo ntawm hluav taws xob shocks thiab tiv thaiv cov cuab yeej los ntawm kev puas tsuaj los ntawm hluav taws xob ua txhaum. Hauv cov tshuab hluav taws xob uas tsis muaj kev sib txuas ntawm lub ntiaj teb, xws li hauv cov kev sib txuas hluav taws xob siab, lub tshuab hluav taws xob hauv av tau teeb tsa kom muaj kev nyab xeeb thiab txhim khu kev qha hauv av.

Earthing transformers feem ntau yog siv nyob rau hauv lub hwj chim transformers, reactor units, thiab fais fab systems. Lawv tau tsim los kom muaj qhov sib piv qis dua li cov pa hluav taws xob hloov pauv, uas txhais tau hais tias lawv tuaj yeem nqa lub siab tam sim no yam tsis tau tsim hluav taws xob siab. Qhov ratio ntawm lub ntiaj teb transformer feem ntau yog teem rau 1: 1, uas txhais tau hais tias cov input voltage thiab output voltage yog tib yam.

Kev tsim ntawm earthing transformers txawv nyob ntawm daim ntawv thov thiab hom hluav taws xob uas nws tau siv nyob rau hauv. Qee qhov earthing transformers yog tsim los ua roj-immersed, hos lwm tus yog qhuav-hom transformers. Kev xaiv ntawm transformer hom thiab tsim yog nyob ntawm qhov tshwj xeeb ntawm cov khoom siv hluav taws xob.

Earthing transformers kuj tseem siv rau hauv cov tshuab hluav taws xob los txo qhov kev hloov pauv ntawm qhov hluav taws xob thiab sib npaug ntawm cov khoom xa tawm. Lawv tuaj yeem siv tau rau hauv cov tshuab hluav taws xob uas muaj cov khoom tsis sib npaug lossis qhov twg muaj qhov hloov pauv loj hauv kev xav tau.

Hauv kev xaus, earthing transformers yog cov khoom tseem ceeb hauv cov tshuab hluav taws xob, muab kev ruaj ntseg thiab txhim khu kev qha hauv av thiab tiv thaiv cov khoom siv hluav taws xob los ntawm kev puas tsuaj los ntawm hluav taws xob tsis raug. Kev tsim thiab kev teeb tsa ntawm lub ntiaj teb transformers yog nyob ntawm qhov yuav tsum tau ntawm cov hluav taws xob tshwj xeeb, thiab lawv ua lub luag haujlwm tseem ceeb hauv hluav taws xob kev nyab xeeb thiab kev ruaj ntseg.

Earthing transformers yog cov khoom tseem ceeb hauv cov tshuab hluav taws xob hluav taws xob, feem ntau tsim los ua kom muaj kev nyab xeeb thiab txhim khu kev lag luam ntawm lub kaw lus. Cov transformers no ua haujlwm rau lub hom phiaj tseem ceeb los ntawm kev sib txuas ntawm qhov nruab nrab ntawm peb theem hluav taws xob faib hluav taws xob rau lub ntiaj teb. Nov yog qee qhov tseem ceeb ntawm earthing transformers:

• Nruab nrab Grounding: Nyob rau hauv peb-theem fais fab system, ib qho ntawm cov conductors raug xaiv los ua qhov nruab nrab, uas feem ntau txuas nrog lub ntiaj teb rau kev nyab xeeb. Lub earthing transformer yog siv los tsim qhov kev sib txuas no. Nws ua kom ntseeg tau tias qhov nruab nrab qhov nruab nrab yog nyob ntawm lossis ze lub ntiaj teb muaj peev xwm.

• Muab cais nyob ib leeg: Earthing transformers yog tsim los nrog kev sib cais thib ob winding. Qhov no txhais tau hais tias lub hauv paus thiab theem nrab windings tsis txuas ncaj qha, muab hluav taws xob cais ntawm qhov system thiab hauv av. Qhov kev sib cais no yog qhov tseem ceeb rau kev nyab xeeb thiab kev ua txhaum.

• Resonance Txhaum: Hauv qee lub tshuab hluav taws xob, cov xwm txheej resonance tuaj yeem tshwm sim vim lub peev xwm ntawm cov kab hluav taws xob ntev. Earthing transformers tuaj yeem pab txo qhov teeb meem no los ntawm kev muab txoj hauv kev qis rau hauv av, tiv thaiv overvoltages thiab kev puas tsuaj rau lub cev.

• Fault Tam sim no txwv: Earthing transformers tuaj yeem nruab nrog grounding resistors los txwv qhov kev txhaum tam sim no thaum muaj kev txhaum hauv av. Qhov no tsis yog tsuas yog tiv thaiv lub kaw lus los ntawm ntau dhau tam sim no tab sis kuj pab nrhiav thiab cais qhov tsis raug sai.

• Hom Earthing Transformers: Muaj ntau hom kev hloov pauv hauv av, suav nrog cov khoom siv hauv av, impedance grounded, thiab tsis kam grounded transformers. Qhov kev xaiv ntawm hom yog nyob ntawm qhov kev xav tau tshwj xeeb ntawm lub zog hluav taws xob thiab qib ntawm kev tiv thaiv kev ua txhaum xav tau.

• Kev nyab xeeb thiab kev ntseeg siab: Kev cog lus hauv av kom zoo los ntawm kev hloov pauv hauv av ua kom muaj kev nyab xeeb ntawm kev teeb tsa hluav taws xob los ntawm kev txo cov kev pheej hmoo ntawm hluav taws xob thiab hluav taws xob. Nws kuj tseem pab kom ntseeg tau tias kev ua haujlwm txhim khu kev qha ntawm lub zog faib hluav taws xob los ntawm kev tiv thaiv theem-rau-hauv av tsis raug thiab qhov tsis sib xws ntawm qhov hluav taws xob.

• Kev tu: Kev saib xyuas tsis tu ncua thiab kev sim ntawm lub ntiaj teb transformers yog qhov tseem ceeb los xyuas kom meej lawv cov txiaj ntsig txuas ntxiv hauv kev muab cov hluav taws xob muaj kev nyab xeeb thiab txhim khu kev qha.
