Hauv cov khoom siv hluav taws xob, qis-voltage switchgear, thiab lub zog tshiab lub zog hluav taws xob, tin- plated tooj liab busbars ua haujlwm tseem ceeb hauv cov khoom siv hluav taws xob; lawv qhov kev ua tau zoo cuam tshuam ncaj qha rau kev nyab xeeb thiab ruaj khov ntawm kev ua haujlwm hauv Circuit Court. Piv rau liab qab tooj liab busbars, tin-plated tooj liab busbars-ua tsaug rau lawv nto tin plating- zoo txo qhov tsis txaus ntawm tooj liab liab liab, xws li susceptibility rau oxidation thiab tsis txaus kub nce tswj. Los ntawm kev tsim txiaj ntawm cov txiaj ntsig tshwj xeeb no, lawv tau siv dav thoob plaws ntau hom kev siv hluav taws xob, thaum kev txhim kho txuas ntxiv hauv busbar txheej thev naus laus zis tau txhim kho lawv cov kev ua tau zoo tag nrho.
Ib qho ntawm cov yam ntxwv tseem ceeb tshaj plaws ntawm lub tin -coated tooj liab busbar yog nws lub peev xwm los ua kom qhov siab tshaj qhov tso cai kub nce thaum lub sijhawm ua haujlwm, yog li txhim kho lub busbar tam sim no - nqa peev xwm; Qhov no suav nrog nws qhov txiaj ntsig tseem ceeb tshaj li liab qab tooj liab busbars. Raws li cov kev cai ntawm GB/T 14048.1-2023, Tsawg-voltage switchgear thiab controlgear - Ntu 1: Cov kev cai dav dav, qhov siab tshaj plaws uas tso cai rau kev sib txuas tooj liab liab yog 60 K, whereas rau tin-coated tooj liab qhov kev txwv no tuaj yeem ncav cuag 60 K. nce qab nthab ncaj qha txiav txim siab nws superior tam sim no-nqa peev.
Raws li kev lag luam tus qauv yuav tsum tau ua- uas teev qhov nruab nrab huab cua kub ntawm 35℃thiab qhov xav tau siab tshaj plaws ntawm 40℃nyob ib ncig ntawm switchgear- nws tuaj yeem xam tau tias qhov siab tshaj plaws kev khiav hauj lwm kub rau liab qab tooj liab busbars yog 100 degree, thaum rau tin -plated tooj liab busbars ncav cuag 5 degree, Nyob rau hauv zoo tib yam qhov siab tshaj plaws qhov kub thiab txias nyob rau hauv lub switchgear txee, rated tam sim no ntawm ib tug tin -plated tooj liab busbar yog ho siab dua li ntawm ib tug liab qab tooj liab busbar; qhov no yog qhov laj thawj tseem ceeb rau nws txoj kev siv dav hauv high-voltage thiab high{10}} ib puag ncig tam sim no.
Lwm qhov tseem ceeb ntawm tinned tooj liab busbars yog lawv lub peev xwm los txo kev sib cuag ntawm cov pob qij txha, yog li txo qhov kub thiab txias ntawm qhov sib txuas. Thaum tam sim no ntws los ntawm ib lub busbar, muaj kev tiv thaiv kev sib cuag ntawm cov pob qij txha tsim kom muaj cua sov ntxiv; Txawm li cas los xij, tin plating ntawm tinned tooj liab busbars optimizes hluav taws xob kev sib cuag. Los ntawm kev muab cov khoom siv hluav taws xob ruaj khov dua (tus cwj pwm los ntawm K- tus nqi zoo sib xws), nws tswj tau qhov kub thiab txias ntawm cov pob qij txha, tiv thaiv cov khoom puas tsuaj uas tuaj yeem tshwm sim los ntawm cov cua kub ntau dhau.
Noj 60 mm × 10 mm ca tooj liab busbar nyob rau hauv ib tug tsawg -voltage switchgear txee raws li piv txwv li: thaum lub busbar qhov kub thiab txias yog 29 K, lub ambient kub yog 40 degree, lub bolt siab ntawm busbars yog 70 N, thiab tam sim no yog 1000 A, qhov kub ntawm lub busbar yog siab dua ntawm qhov sib koom ua ke. Qhov no qhia tau hais tias tin plating zoo tswj kev sib cuag - ntsig txog qhov kub thiab txias, yog li ua kom muaj kev ruaj ntseg ntawm cov hluav taws xob hluav taws xob- uas yog qhov tseem ceeb ntawm kev siv tin plating rau cov tooj liab busbars.
Tiv thaiv cov oxidation ntawm tooj liab ntawm kev sib txuas sib txuas yog ib qho ntawm cov txiaj ntsig zoo ntawm tinned tooj liab busbars, ua kom muaj txiaj ntsig zoo rau lawv lub neej kev pab thiab kev ntseeg tag nrho. Qhov sib tshooj ntawm cov tooj liab liab busbars yog qhov ua rau oxidation thaum raug cov dej noo, ua rau muaj zog tiv thaiv thiab kub siab. Ib txheej tin plating, txawm li cas los xij, muab kev tiv thaiv zoo los ntawm kev cais cov tooj liab substrate los ntawm cov dej noo, yog li tiv thaiv oxidation - qhov no yog qhov tseem ceeb ntawm tinned tooj liab busbars.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias tin - txheej txheem plating rau Tinned Copper Flat Bars poob rau hauv ob pawg: tag nrho - ntev plating thiab plating tsuas yog siv rau qhov chaw sib cuag. Yog tias plating tsuas yog txwv rau qhov chaw sib cuag, tin txheej yuav raug rau corrosion; yog li ntawd, cov cua sov-shrink tubing yuav tsum tau siv rau ntawm ciam teb ntawm cov plated thiab liab qab tooj liab seem kom tsis txhob ya raws. Tsis tas li ntawd, thaum lub sij hawm thauj mus los thiab khaws cia, tin plating yuav tsum tau tiv thaiv kom tsis txhob muaj kev puas tsuaj rau lub cev. Tsis tas li ntawd, lub thickness ntawm cov tin txheej yuav tsum nruj me ntsis ua raws li cov qauv kev lag luam muaj feem xyuam rau cov txheej txheem kev lag luam - ib qho tseem ceeb rau kev siv kom zoo thiab nyab xeeb ntawm Tinned Copper Flat Bars.
Yog tias koj muaj lus nug lossis cov cai tshwj xeeb hais txog kev xaiv lossis kev thovTin-Plated Copper Busbars-lossis yog tias koj xav tau ib qho kev daws teeb meem raws li kev cai-peb caw koj tiv tauj peb. Peb tau cog lus tias yuav muab cov kev taw qhia thiab cov kev daws teeb meem zoo rau koj, yog li pab kom muaj kev nyab xeeb thiab ruaj khov ntawm koj cov hluav taws xob circuits.
