Khoom Description
Lub 27kV Auto Recloser muaj cov kev ua tau zoo ntawm cov tub ntxhais kawm, suav nrog cov ntsuas tam sim no ntawm 630 A, ua kom muaj kev ruaj ntseg nyob rau hauv lub zog xa hluav taws xob ntawm nruab nrab - thiab siab -voltage tis networks. Nws muaj qhov ntsuas luv luv-circuit breaking tam sim no ntawm 16 kA, ntsuas luv luv-circuit ua tam sim no thiab ntsuas peak tiv taus tam sim no ntawm 40 kA, thiab ntsuas luv luv -lub sijhawm tiv taus tam sim no ntawm 16 kA rau 3 vib nas this.
Cov cuab yeej tuaj yeem teb tau sai sai rau luv luv- Circuit Court tsis ua haujlwm, cuam tshuam kev cuam tshuam tam sim no, thiab tiv taus luv luv - lub sijhawm cuam tshuam tam sim no. Thaum ua ke nrog nws tsis siv neeg rov ua haujlwm, nws tuaj yeem rov qab tau lub zog sai sai, txo qis hluav taws xob poob.
Kev ua haujlwm tau zoo yog qhov tseeb thiab ua tau zoo, ua raws li qhov ntsuas kev ua haujlwm ntawm "O-0.2 s-CO-2 s-CO-2 s-CO-2 s-CO." Kaw thiab qhib tib lub sijhawm tsawg dua lossis sib npaug li 2 ms, kev sib cuag bounce tsawg dua lossis sib npaug li 3 ms, lub sijhawm kaw tsawg dua lossis sib npaug li 60 ms, thiab lub sijhawm qhib tsawg dua lossis sib npaug li 40 ms. Lub recloser ua haujlwm hluav taws xob nrog cov ntsuas ntsuas hluav taws xob ntawm DC 220 V, muab cov lus teb ceev thiab tswj tau yooj yim.
Kev rwb thaiv tsev ua tau raws li cov qauv kev lag luam siab. Lub 1-feeb feeb-frequency withstand voltage (RMS) rau kev hloov kev sib cuag, theem- rau-theem, thiab theem- rau hauv av yog 60 kV, hos lub xob laim impulse withstand voltage (peak) rau tib txoj kev rwb thaiv tsev yog 150 kV. Kev tso tawm ib nrab yog tsawg dua lossis sib npaug li 10 pC ntawm qhov ntsuas hluav taws xob ntawm 1.2Ur / √3. Cov yam ntxwv no ua rau cov cuab yeej siv tau zoo tiv thaiv kab hluav taws xob overvoltage surges thiab muaj feem cuam tshuam rau kev tso tawm, ua kom muaj kev nyab xeeb ntawm rwb thaiv tsev nyob rau hauv kev ua haujlwm nyuaj.
Lub 27kV Auto Recloser yog dav siv hauv nroog nruab nrab - thiab siab -voltage distribution network renovation projects, smart substation building, industrial park power distribution system upgrades, new energy plant grid-connection projects, and in the country power grid modernization initiatives. Nws ua tau raws li kev tiv thaiv thiab kev tswj cov kev cai ntawm cov kev faib tawm ib txwm siv thaum ua raws li txoj kev loj hlob mus rau automation thiab efficiency nyob rau hauv cov phiajcim ntse, muab kev txhawb zog rau kev nyab xeeb, tsis tu ncua, thiab kev ua haujlwm ruaj khov ntawm lub zog hluav taws xob.
