Lub high-voltage isolating hloov nws tus kheej tsis muaj arc extinguishing muaj nuj nqi. Lub high-voltage fuse tsis tuaj yeem siv los ua lossis tawg tam sim no, thiab tsis tuaj yeem cuam tshuam qhov luv-circuit tam sim no. Nws tsuas yog siv tau rau qee qhov kev hloov pauv uas yuav tsis ua rau muaj zog arcs, xws li voltage transformers, High-voltage control khoom siv rau xob laim ntes, transformers, metering txee thiab lwm yam khoom siv, los yog txuas nrog high-voltage Circuit Court breakers kom ntseeg tau thaum lub sij hawm. fais fab tuag.
Lub high-voltage cais hloov tsis pub ua haujlwm nrog kev thauj khoom. Qhov kev khiav hauj lwm ib txwm muaj ntawm 10kv rho tawm hloov pauv yog lub siab-voltage phab ntsa bushing uas txuas thiab disconnects lub voltage transformer thiab xob laim pas nrig, lub charger Circuit Court ntawm lub busbar, thiab tsis muaj load capacitance txaus tsis ntau tshaj 5A. Tsis muaj-load transformers nrog kab thiab on-off excitation tam sim no tsis tshaj 2A.
Lub peev xwm hloov pauv ntawm qhov hloov hluav taws xob high-voltage rho tawm rau cov kab tsis muaj kab yog txwv raws li qhov tseeb tias qhov qhib thiab kaw qhov ntev ntawm sab nraum zoov qhov hluav taws xob hluav taws xob cais tawm tsis tuaj yeem tshaj qhov tsis muaj tam sim no ntawm cov kab hluav taws xob ntawm 10km. Rau high-voltage load switches, rau unloaded cable kab, lub capacitance tam sim no ntawm high-voltage tam sim no-limiting fuses yog siab tshaj ntawm cov overhead circuits ntawm tib ntev. Yog li ntawd, qhov ntev tsis tuaj yeem siv los txwv nws. Qib 5A tsuas yog siv tau los ua tus qauv rau cov hluav taws xob hluav taws xob sib cais.
Qhov kev ua tau zoo ntawm cov hluav taws xob hluav taws xob hluav taws xob sib cais rau qhov tsis muaj hluav taws xob hloov hluav taws xob tau teev tseg raws li cov qub-fashioned transformers los ntawm ib ncig ntawm 1950s. Txawm li cas los xij, vim qhov loj tsis muaj qhov tam sim no ntawm cov transformers nyob rau lub sijhawm ntawd, qhov kev txwv ntawm kev sib cais ntawm qhov kev tawm ntawm lub peev xwm kuj tseem tsawg. Txawm hais tias tam sim no kev rho tawm cov hloov pauv thiab cov hloov pauv tau hloov pauv hauv kev ua tau zoo, vim tias tsis muaj qhov qhia meej meej, cov fuses tso tawm tsuas yog ntsuas kom tsis pub dhau 2A.
