Product Description

GN27-40.5(C)(D) hom high voltage isolator hloov, haum rau kev teeb tsa sab hauv tsev nrog qhov ntsuas hluav taws xob ntawm 40.5kV thiab peb theem AC zaus ntawm 50Hz. Muaj cov kev ntsuas tam sim no yog 400A, 630A, 1250A, 2000A, thiab 2500A. Raws li cov khoom tshiab los hloov cov qub qub disconnect keyboards, nws cov qauv tsim nrog cov riam hauv av sib xyaw ua ke ob txoj haujlwm ntawm "kev rho tawm + av". Nrog rau kev quab yuam cov neeg kho tshuab, nws tuaj yeem zam kev ua haujlwm txaus ntshai xws li hauv av thaum muaj zog lossis kaw qhov hloov pauv thaum lub hauv paus, thiab tsim nyog rau cov kev cai rwb thaiv tsev ntawm Chav Kawm II cov pa phem. Tsim nyog rau kev sib txuas thiab hloov hluav taws xob nyob rau hauv voltage-ntawm-xov xwm xav tau. Yuav siv tau nrog high-voltage switchgear los yog ntsia ntawm nws tus kheej ntawm phab ntsa sab hauv.

DL/T 486-2010 Kev Cai Lij Choj rau Kev Txiav Txim AC High Voltage Disconnecting Switches thiab Grounding Switches

Core nta:

1. Nrog grounding hloov + mechanical interlock: Txhawb peb txoj haujlwm: "main switch kaw + grounding switch open", "main switch open + grounding switch open", thiab "main switch open + grounding switch kaw". Cov neeg kho tshuab cuam tshuam yuam kev tiv thaiv "hauv av thaum muaj zog" thiab "kaw nrog av", ua raws li cov cai tswj kev nyab xeeb.

2. Muaj zog rwb thaiv tsev tsim: Ua haujlwm loj creepage nrug tom qab insulators (tsim rau chav II muaj kuab paug ib puag ncig), nrog rwb thaiv tsev kev ua tau zoo raws li qhov xav tau ntawm 35kV systems; lub rotating ncej yog nruab nrog bearings, ua hauj lwm yooj yim thiab nrog ib tug lifespan ntau tshaj los yog sib npaug rau 2000 cycles.

3. High-cov qauv kev ua haujlwm tau zoo: Lub sab tawg nta lub viav vias- hom ntau- kev sib cuag, nrog ib qho tsis tshua muaj -thov kev sib cuag, tsis tshua muaj hnav, thiab thaj chaw tshav kub loj (tsim rau siab - tam sim no scenarios); kev tiv tauj teb muaj tus kheej - tu lub peev xwm, txo kev tiv thaiv kev tiv thaiv.

Ordering cov lus qhia:

Cov qauv khoom, ntsuas voltage, thiab ntsuas tam sim no yuav tsum tau qhia meej meej, xws li GN27-40.5D / 1250.

Thov qhia hom kev khiav hauj lwm mechanism (manual/electric). Yog tias xaiv lub tshuab hluav taws xob, lub cev muaj zog thiab tswj qhov hluav taws xob yuav tsum tau qhia.

Thov qhia cov txheej txheem hauv av (ib qho hauv av / ob chav hauv av) thiab seb puas yuav tsum muaj cov khoom tiv thaiv ntxiv xws li cov ntsuas hluav taws xob lossis cov ntsuas ntsuas ntsuas.

Yog tias xav tau cov insulators sib xyaw, qhov no yuav tsum tau teev cais.

Cov txheej txheem ua haujlwm:

Thaum ua haujlwm manually, xyuas kom meej tias cov xwm txheej cuam tshuam ua raws li kev khiav hauj lwm logic ua ntej ua qhov qhib / kaw lossis hauv av los ntawm kev tig tus kov horizontally. Yog tias jamming tshwm sim thaum lub sijhawm ua haujlwm, tsis txhob yuam nws; daws qhov teeb meem ua ntej rov pib ua haujlwm.

Ua ntej kev khiav hauj lwm hluav taws xob, xyuas kom meej tias lub cev muaj zog thiab tswj qhov hluav taws xob yog qhov qub, thiab kuaj qhov ruaj khov ntawm cov teeb liab kis tau tus mob. Thawj - lub sijhawm ua haujlwm, nws raug nquahu kom simulate manually ua ntej hloov mus rau hom hluav taws xob.
