Lub capacitor switching contactor yog cov khoom siv hluav taws xob tshwj xeeb tsim los txuas thiab txiav tawm qis -voltage shunt capacitor. Nws yog feem ntau siv nyob rau hauv qis -voltage tsis siv neeg reactive fais fab kev them nyiaj systems rau txuas los yog disconnect shunt capacitors nyob rau hauv thiaj li yuav kho lub hwj chim ntawm lub hwj chim system. Piv nrog rau tus qauv contactors, nws cov yam ntxwv tseem ceeb suav nrog kev tsim -inrush tam sim no supposed ntaus ntawv thiab ib tug tshwj xeeb kev sib cuag ua ntu zus, uas yog tsim los lis loj inrush tam sim no thiab overvoltage generated thaum lub sij hawm kev twb kev txuas thiab disconnection ntawm capacitors.
Cov Txheej Txheem Txheej Txheem tseem ceeb thiab cov txheej txheem xaiv
Thaum xaiv ib tug contactor, xyuas kom meej tias nws tsis haum lub capacitor bank thiab system tej yam kev mob. Cov txheej txheem tseem ceeb muaj xws li:
Rated kev khiav hauj lwm voltage (Ue): Cov txiaj ntsig muaj xws li 380V, 400V, 660V, thiab lwm yam.
Rated kev khiav hauj lwm tam sim no (Ie): Yuav tsum tshaj qhov ruaj khov- lub xeev kev khiav hauj lwm tam sim no ntawm lub tuam txhab tswj capacitor. Cov kev ntsuas feem ntau suav nrog 25A, 32A, 43A, 63A, 95A, 115A, 150A, thiab 170A.
Kev Tswjhwm Capacitor Capacity (kvar): Qhov siab tshaj plaws capacitor muaj peev xwm uas tus contactor tuaj yeem hloov pauv yam xyuam xim nyob ntawm qhov ntsuas hluav taws xob. Piv txwv li, CJ19C-63 muaj peev xwm tswj tau kwv yees li 30 kvar ntawm 380V, thaum CJ19C-150 muaj peev xwm sib xws ntawm 20V voltage ntawm 20 V.
Inrush tam sim no muaj peev xwm tiv thaiv: Feem ntau, lub ncov inrush tam sim no thaum kaw tuaj yeem txwv tsis pub dhau 20 npaug ntawm qhov ntsuas tam sim no.
Lub neej hluav taws xob thiab tshuab hluav taws xob: Raws li kev ntsuas ntsuas, lub neej hluav taws xob feem ntau tsis muaj tsawg dua 100,000 kev ua haujlwm, thaum lub neej siv tshuab tuaj yeem ncav cuag 1 lab kev ua haujlwm.
