Qhov no yog qhov teeb meem tseem ceeb thiab tseem ceeb ntawm lub zog hluav taws xob. Thaum qhov qis- qhov hluav taws xob sab poob qis tab sis qhov siab - lub tshuab nqus tsev vacuum Circuit Court breaker tsis mus, qhov no yog qhov qub thiab ua raws li cov qauv kev tiv thaiv hluav taws xob.
Lub logic ntawm lub siab -voltage circuit breaker yog txiav txim siab los ntawm nws cov khoom tiv thaiv relay, uas feem ntau tsis saib xyuas seb qhov qis -voltage sab puas poob voltage.
Hauv qab no, peb muab cov lus piav qhia ntxaws ntxaws ntawm cov hauv paus ntsiab lus thiab txheeb xyuas cov xwm txheej uas koj yuav "xav tau" nws mus ncig.
Qhov laj thawj tseem ceeb: Kev Tiv Thaiv Sib txawv thiab lub luag haujlwm
Nws cov xwm txheej tripping feem ntau suav nrog:
Kev tiv thaiv overcurrent: luv luv lossis hnyav dhau ntawm qhov siab -voltage sab.
Kev Tiv Thaiv Instantaneous: Kev luv luv luv luv ntawm qhov siab -voltage sab.
Zero-Kev Tiv Thaiv Kab Mob (Kev Tiv Thaiv Hauv av): Ib qho - theem hauv av txhaum ntawm qhov siab -voltage sab.
Transformer lub cev tiv thaiv (ntawm cov roj relays, kub sensors, thiab lwm yam): Internal transformer faults. Qhov qis- qhov hluav taws xob sab hluav taws xob hluav taws xob (piv txwv li, qhov poob ntawm qhov hluav taws xob) tsis poob rau hauv ib qho ntawm cov teeb meem saum toj no. Rau qhov siab -voltage sab, qhov no sawv cev rau ib txwm ua haujlwm ntawm lub teeb lossis tsis muaj load, tsis muaj kev phom sij. Yog li ntawd, lub siab -voltage Circuit Court breaker tsis muaj laj thawj mus.
Tej Yam Ua Tau Ua Rau Tsawg-Voltage Side Fais Fab (Yuav tsum tau tuav los ntawm "Tsev Tub Ceev Xwm")
Ntau qhov ua rau muaj rau qhov qis -voltage sab fais fab poob, xws li:
- Tsawg-voltage main switch tripping vim overload los yog luv luv Circuit Court
- Tsawg-voltage kab txhaum
- Tib neeg yuam kev ua rau muaj kev sib tsoo ntawm qhov qis -voltage hloov
- Tsis muaj teeb meem nyob rau hauv lub transformer nws tus kheej
Cov teeb meem no yuav tsum tau daws nws tus kheej los ntawm kev sib raug qis -voltage side tiv thaiv cov cuab yeej (tsawg-voltage circuit breakers, fuses)) yam tsis muaj "alarming" siab -voltage side tiv thaiv. Qhov no ua raws li lub hauv paus ntsiab lus ntawm "kev cais tawm hauv cheeb tsam," txo qhov kev siv hluav taws xob tsawg.
Raws li qhov xwm txheej dab tsi koj yuav "xav tau" lossis "yuav tsum tau" lub siab -voltage Circuit Court breaker mus ncig thaum lub sijhawm qis -voltage outage?
Certain specialized automation or safety interlock requirements necessitate implementing the "low-voltage loss ->high-voltage trip" functionality. Txawm li cas los xij, qhov no tsis yog ib qho kev tiv thaiv tus qauv tab sis yog ib qho kev sib txuas ntxiv.
Ua raws li qhov no yuav tsum muaj lub teeb liab thiab cov cuab yeej tseem ceeb: qhov qis -voltage sab voltage teeb liab thiab qhov hluav taws xob poob tiv thaiv relay.
Lub hauv paus ntsiab lus ua haujlwm yog raws li nram no:
kub muag khoom
LTZ-40.5 sab hauv tsev SF6 Circuit Court breakertsim los ntawmShaanxi West Fais Fab Tongzhong Hluav Taws Xob Co., Ltd.yog ib qho khoom siv sab hauv tsev siv hauv AC 50Hz peb -theem fais fab system. Nws tuaj yeem siv rau hauv kev lag luam thiab kev lag luam mining, fais fab nroj tsuag thiab substations rau kev tswj thiab kev tiv thaiv cov khoom siv hluav taws xob, thiab tuaj yeem siv rau hauv qhov chaw uas yuav tsum tau ua haujlwm ntau zaus, thiab tuaj yeem siv los ua kev sib txuas lus Circuit Court breaker thiab tsim nyog rau capacitor bank circuit breaker, thiab yog cov roj zoo tshaj plaws - dawb Circuit Court breaker nyob rau hauv lub hwj chim system.
Peb tuaj yeem koom tes li cas?
