Khoom Description
Qhov no sab nraum zoov hluav taws xob hluav taws xob hluav taws xob hluav taws xob muaj qhov ua kom zoo sab nraum zoov- cov qauv tshwj xeeb thiab yog tsim los siv cov khoom siv siab - zoo, huab cua- cov ntaub ntawv tiv taus, tso cai rau nws tiv taus huab cua sab nraum zoov xws li kub thiab qis, nag, daus, cua, thiab xuab zeb yaig. Nws muaj lub neej txhua yam txog li 10,000 lub voj voog ua haujlwm thiab muaj peev xwm ua tau 30 luv- Circuit Court breaking operations ntawm qhov luv luv -circuit breaking tam sim no, ua rau nws zoo haum rau ntev -lub sij hawm siv nyob rau hauv siab - zaus ua hauj lwm scenarios. durability thiab stability.
- Nyob rau hauv cov nqe lus ntawm kev ua tau zoo tsis, lub sab nraum zoov high voltage Circuit Court breaker muab hloov tau yooj yim adaptability. Rated tam sim no cov kev xaiv ntawm 630 A thiab 1250 A yog muaj los ua kom tau raws li qhov sib txawv ntawm cov khoom siv hluav taws xob. Rated luv-circuit breaking tam sim no xaiv muaj xws li 20 kA thiab 25 kA, nrog rau cov ntsuas peak tiv taus tam sim no thiab ntsuas luv luv -circuit ua tam sim no xaiv ntawm 50 kA lossis 63 kA. Qhov ntsuas luv luv-lub sij hawm tiv taus tam sim no yog 20 kA rau 4 vib nas this, ua kom cov lus teb ceev ceev thaum muaj kev ua txhaum los cuam tshuam kev cuam tshuam kev cuam tshuam thiab tiv thaiv kev puas tsuaj rau cov khoom siv thiab cov kab.
- Kev ua haujlwm rwb thaiv tsev nruj me ntsis ua raws li cov qauv kev lag luam siab. Lub hwj chim- zaus tiv taus qhov hluav taws xob (1 feeb) yog 34 kV nyob rau hauv cov dej ntub dej, thiab 42 kV theem-rau-theem thiab theem- rau- hauv av, nrog rau 48 kV thoob plaws kev sib cuag, nyob rau hauv qhuav qhuav. Lub zog hluav taws xob tiv taus hluav taws xob (ncej) yog 75 kV theem- rau-theem thiab theem- rau- hauv av, thiab 85 kV thoob plaws cov neeg sib cuag, muab kev tiv thaiv zoo rau lub zog hluav taws xob overvoltage surges. Tsis tas li ntawd, lub voj voog thib ob muaj 1-feeb fais fab zaus tiv taus qhov hluav taws xob ntawm 2 kV, ua kom muaj kev nyab xeeb ntxiv.
Kev tsim qauv ua haujlwm ua raws li kev tshawb fawb tau hais los ntawm "Qhib - 0.3 s - Kaw - Qhib - 180 s - Kaw-Qhib," kom ntseeg tau meej thiab nrawm nrawm thaum txo qis kev ua haujlwm thiab kev saib xyuas nyuaj.
Cov khoom no muaj ntau yam kev siv thiab feem ntau tsim nyog rau kev tiv thaiv thiab kev tswj hauv substations thiab fais fab faib tshuab ntawm kev lag luam thiab mining lag luam. Nws kuj yog qhov zoo tagnrho rau cov kab hluav taws xob nyob deb nroog thiab lwm qhov chaw uas yuav tsum tau ua haujlwm ntau zaus. Txawm hais tias siv los txhim kho cov khoom siv hluav taws xob ib txwm muaj lossis tsim cov kev faib tawm tshiab, nws ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev ua haujlwm zoo, ruaj khov, thiab muaj kev nyab xeeb ntawm cov tshuab hluav taws xob.
