CN-12/630-25 khoom insulated nplhaib network switchgear yog ib tiam tshiab ntawm ib puag ncig tus phooj ywg composite insulated nplhaib network txee. Nws yog tag nrho kaw lub hwj huam mov unit. Txhua qhov chaw nyob thiab cov keyboards raug kaw tag nrho hauv lub plhaub yas epoxy. Tsis muaj SF roj hauv lub plhaub. Tag nrho cov cuab yeej hloov pauv tsis cuam tshuam los ntawm ib puag ncig sab nraud, ua kom muaj kev ntseeg tau ntawm kev ua haujlwm thiab kev nyab xeeb ntawm tus kheej, thiab Kev Kho-dawb yog tiav.

Cov khoom siv hluav taws xob lub nplhaib hluav taws xob yog tsim los ntawm peb hom kev hloov pauv, uas yog V unit (circuit breaker unit), C unit (load switch unit), thiab F unit (combined hluav taws xob unit). Txhua chav yuav siv tau ib leeg lossis nthuav dav. Nws cov qauv tau muab faib ua Kev txawj ntse tswj ntawm chav ntsuas, kev khiav hauj lwm mechanism thiab thawj feem. Chav ntsuas ntsuas tuaj yeem nruab nrog microcomputer tiv thaiv (controller). Thawj feem txais APG tsis siv neeg gel txheej txheem kom tiav kaw qhov kev sib cais hloov thiab arc extinguishing chamber nyob rau hauv epoxy resin, thiab muaj ib tug mob siab rau lub connector txuas nrog lub busbar. Lub arc extinguishing chamber siv tshwj xeeb tooj liab-chromium cov ntaub ntawv tiv tauj, R-hom longitudinal magnetic teb tiv tauj, thiab ua tiav ib zaug sealing thiab tawm txheej txheem. Lub arc extinguishing chamber qhov tawg luv-circuit tam sim no muaj peev xwm thiab stability, hluav taws xob lub neej, kub nce thiab rwb thaiv tsev theem siab dua ua ntej. Lub arc extinguishing chamber (tooj liab-aluminium hu rau cov khoom, khob-zoo li tus longitudinal magnetic teb kev sib cuag qauv, thiab tsis tiav ib-lub sij hawm sealing thiab kev npaj txheej txheem) tau zoo heev. Cov txheej txheem kev ua haujlwm tau txais kev ua haujlwm ywj pheej nrog kev hloov pauv, uas yog, qhov hloov pauv hloov pauv thiab lub ntsiab hloov elastic kev ua haujlwm tau muab tso rau hauv tag nrho, uas tuaj yeem pab txhawb kev sib cuam tshuam, thiab muaj qhov tsawg dua, txo cov kev sib txuas tsis tsim nyog, kev ntseeg siab, thiab hluav taws xob ua haujlwm tuaj yeem ua tiav raws li cov neeg siv xav tau.

Cov khoom siv insulated tag nrho cov khoom siv hluav taws xob: Nws siv cov khoom siv insulating los ua cov khoom siv hluav taws xob tseem ceeb hauv nruab nrab thiab kev sib txuas, kev sib txuas sib txuas, cov hloov hauv av, lub ntsiab busbars, ceg busbars thiab lwm yam tseem ceeb conductive circuits singly los yog ua ke, thiab tom qab ntawd npog thiab ntim nrog cov khoom nruab nrab insulating rau hauv ib los yog ntau dua Ib qho module uas muaj qee yam haujlwm uas tuaj yeem rov ua dua lossis nthuav dav thiab muaj cov ntaub ntawv pov thawj thiab cov khoom ntim tag nrho.

Lub nplhaib network chav tsev yog tsim rau 12kV, 5OHz peb-theem AC fais fab kev faib system, thiab yog siv rau lub nplhaib network fais fab mov los yog Zhongyuan fais fab mov. Lub nplhaib network tuaj yeem ntsia tau rau hauv lub zog faib hluav taws xob ntawm kev lag luam thiab kev lag luam mining, thaj chaw nyob, tsev kawm ntawv, chaw ua si, thiab lwm yam. Nws kuj tseem tuaj yeem ntsia tau rau hauv lub thawv compact-hom substations rau kev tswj thiab kev tiv thaiv ntawm kev faib transformers. Yog li ntawd, ob qho tib si sab hauv tsev thiab sab nraum zoov lub nplhaib network tuaj yeem paub txog kev faib hluav taws xob automation.

◆ Kev rho riam pom kev puas tsuaj

Muaj qhov pom tseeb qhov rais rau qhov kev sib cais ntawm qhov tawg nyob rau hauv pem hauv ntej ntawm lub txee. Koj tuaj yeem tshawb xyuas qhov kev sib cais kaw qhov chaw, qhov kev sib cais cais, thiab qhov chaw kaw hauv av. Peb txoj haujlwm ua haujlwm yog qhov yooj yim rau cov neeg ua haujlwm hauv chaw kuaj xyuas thiab txiav txim siab txoj haujlwm ntawm rab riam cais, uas muaj kev nyab xeeb heev.

◆ Kev tsim kho lub siab

Internal arc siab valve: Thaum arcing tshwm sim hauv cov khoom, lub siab yuav raug tso tawm los ntawm lub siab tso tawm valve thiab arcing yuav raug tso tawm mus rau lub cable trench kom tsis txhob raug mob rau tus neeg teb xov tooj.

◆ Ntsuab thiab ib puag ncig tus phooj ywg

Nws yog tsim los nrog ib puag ncig tus phooj ywg cov ntaub ntawv, tsis siv SFg gas li arc extinguishing nruab nrab thiab rwb thaiv tsev, thiab tsis muaj kuab paug rau ib puag ncig. Lub hauv paus Circuit Court siv qhov kev sib cuag tsawg kawg nkaus kom ntseeg tau tias kev siv hluav taws xob tsawg thaum ua haujlwm.
