Lub disconnector (disconnector) txhais tau hais tias thaum nws nyob rau hauv txoj hauj lwm sub, muaj ib qho kev ncua deb ntawm rwb thaiv tsev thiab ib qho pom tseeb disconnection cim ntawm cov neeg uas ua tau raws li cov kev cai;thaum nws nyob rau hauv qhov chaw kaw, nws tuaj yeem nqa tau qhov tam sim no nyob rau hauv ib puag ncig Circuit Court tej yam kev mob thiab txawv txav nyob rau hauv lub sij hawm teev (xws li luv luv Circuit Court) tam sim no switching ntaus ntawv.
Qhov kev hloov pauv uas peb tab tom tham txog feem ntau yog hais txog kev hloov pauv hluav taws xob hluav taws xob siab, uas yog, kev hloov pauv hloov nrog qhov ntsuas hluav taws xob ntawm 1kv thiab siab dua, feem ntau hu ua kev hloov pauv hloov, uas yog cov khoom siv hluav taws xob feem ntau siv hauv high- cov khoom siv hluav taws xob hloov hluav taws xob.Thiab cov qauv yog qhov yooj yim, tab sis vim yog qhov siv ntau thiab cov kev xav tau siab rau kev ua haujlwm kev ntseeg siab, nws muaj kev cuam tshuam zoo rau kev tsim, tsim thiab kev nyab xeeb ntawm kev ua haujlwm ntawm substations thiab fais fab nroj tsuag.Lub ntsiab feature ntawm rab riam hloov yog tias nws tsis muaj peev xwm tua hluav taws, thiab tuaj yeem faib thiab kaw qhov hluav taws xob tsis muaj kev thauj khoom tam sim no.
Kev rho tawm hloov feem ntau siv hauv cov pob zeb mine keyboards:
1) Tom qab qhib, tsim kom muaj qhov sib txawv ntawm cov rwb thaiv tsev ruaj khov, thiab cais cov khoom siv lossis cov kab uas yuav tsum tau kho los ntawm cov khoom siv hluav taws xob nrog rau qhov pom tseeb ntawm kev sib txuas kom ntseeg tau tias muaj kev nyab xeeb ntawm cov neeg ua haujlwm tu thiab cov khoom siv.
2) Raws li kev ua haujlwm xav tau, hloov cov kab.
3) Nws tuaj yeem siv los faib thiab sib txuas me me tam sim no hauv kab, xws li them tam sim no ntawm bushings, busbars, connectors, luv cables, capacitive tam sim no ntawm kev hloov ntsuas capacitors, circulating tam sim no thaum ob chav busbars hloov thiab excitation. tam sim no ntawm voltage transformers Tos.
4) Raws li qhov xwm txheej tshwj xeeb ntawm cov qauv sib txawv, nws tuaj yeem siv los faib thiab sib txuas cov tsis muaj kev txhawb nqa tam sim no ntawm qee lub peev xwm transformer.
Raws li cov txheej txheem kev teeb tsa sib txawv, cov hluav taws xob hluav taws xob hluav taws xob sib cais tuaj yeem muab faib rau sab nraum zoov hluav taws xob hluav taws xob hluav taws xob hluav taws xob thiab cov hluav taws xob hluav taws xob sab hauv tsev.Sab nraum zoov high-voltage isolating keyboards xa mus rau high-voltage isolating keyboards uas tuaj yeem tiv taus qhov cuam tshuam ntawm cua, nag, daus, av, condensation, dej khov thiab tuab te, thiab tsim nyog rau kev teeb tsa ntawm terraces.Nws tuaj yeem muab faib ua ib kem disconnector, ob-kem disconnector thiab peb-kem disconnector raws li cov qauv ntawm nws cov insulating struts.Ntawm lawv, ib leeg-kem riam hloov ncaj qha siv qhov chaw ntsug raws li cov hluav taws xob rwb thaiv tsev ntawm cov pob txha tawg nyob rau hauv lub overhead busbar.Yog li ntawd, nws muaj qhov pom tseeb zoo ntawm kev txuag chaw hauv pem teb, txo cov hlau lead, thiab tib lub sijhawm, qhov qhib thiab kaw lub xeev yog qhov tseeb tshwj xeeb.Nyob rau hauv cov ntaub ntawv ntawm ultra-high voltage fais fab kis tau tus mob, cov nyhuv ntawm kev txuag hauv pem teb qhov chaw yog qhov tseem ceeb dua tom qab ib leeg-kem riam hloov yog siv nyob rau hauv lub substation.
Hauv cov khoom siv hluav taws xob tsawg, nws yog qhov tsim nyog rau cov khoom siv hluav taws xob tsawg-voltage terminal fais fab kev faib khoom xws li cov tsev nyob thiab cov tsev.Lub luag haujlwm tseem ceeb: nrog kev thauj khoom tawg thiab txuas kab
nta
1. Thaum cov khoom siv hluav taws xob tau kho dua tshiab, lub sijhawm hluav taws xob tau muab, thiab nws yog ib qho kev cuam tshuam pom tseeb los xyuas kom meej qhov kev nyab xeeb ntawm cov neeg ua haujlwm tu.
2. Cov kev hloov pauv tsis tuaj yeem ua haujlwm nrog kev thauj khoom: nws tsis tuaj yeem ua haujlwm nrog cov khoom ntsuas lossis cov khoom loj, thiab tsis tuaj yeem faib thiab sib txuas cov khoom thauj tam sim no thiab luv luv tam sim no, tab sis cov neeg uas muaj qhov hluav taws xob tua hluav taws tuaj yeem ua haujlwm nrog cov khoom me me thiab tsis muaj kab. .
3. Nyob rau hauv dav dav kev xa hluav taws xob ua haujlwm: thawj zaug kaw qhov kev rho tawm, tom qab ntawd kaw qhov hluav taws xob hluav taws xob lossis hloov chaw thauj khoom;Thaum lub tshuab hluav taws xob cais tawm yog tawm: thawj zaug disconnect lub Circuit Court breaker los yog load hloov, ces disconnect tus rho tawm.
4. Kev xaiv tsis txawv ntawm lwm yam khoom siv hluav taws xob, txhua yam yuav tsum tau ntsuas qhov ntsuas hluav taws xob, ntsuas tam sim no, dynamic ruaj khov tam sim no, thermal ruaj khov tam sim no, thiab lwm yam yuav tsum tau ua raws li qhov xav tau ntawm daim ntawv thov.
Lub luag haujlwm ntawm kev rho tawm yog txiav tawm lub voj voog ntawm qhov tsis muaj kev thauj khoom tam sim no, kom cov khoom siv kho thiab lub zog hluav taws xob muaj qhov cuam tshuam pom tseeb los xyuas kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm tu.Qhov kev rho tawm tsis tuaj yeem txiav tawm qhov tam sim no thiab luv luv-circuit tam sim no yam tsis muaj qhov tshwj xeeb arc extinguishing ntaus ntawv., yog li qhov kev rho tawm tuaj yeem ua haujlwm tsuas yog thaum lub tshuab hluav taws xob raug txiav tawm los ntawm lub tshuab hluav taws xob.
