LV Drawers yog siv rau cov hluav taws xob faib hluav taws xob thiab yog qhov yooj yim. Ntev npaum li cov ntaub ntawv molded Circuit Court breaker tuaj yeem ntsia tau, cov khoom siv tooj liab ntawm 630A siab tam sim no fais fab tuag tub rau khoom yog yooj yim los npaj. Copper bar kev twb kev txuas yog sib npaug rau kho lub plug nyob rau hauv ib txoj hauj lwm, uas yog tsis conducive rau aligning sab laug thiab txoj hauj lwm ntawm cov neeg sib cuag thiab tej zaum yuav ua rau unilateral contact ntawm lub plug. Siv ob lub clamps tuaj yeem zam kev sib cuag ntawm lub ntsaws los ntawm kev sib txawv ntawm lub tub rau khoom lossis lub zog ntxiv ntawm lub ntsaws. Lub qub B txee siv cov kev sib txuas ntawm cable thiab yuav tsum muaj ntau lub ntsaws ntsaws. Txhawm rau kom ntseeg tau tias lub tub rau khoom tsis qaij rov qab, kuj tseem muaj qhov chaw ntsaws lub rooj tsavxwm rau ntawm sab saud.

 

Burnout Fault thiab Countermeasures ntawm MNS Tsawg Voltage Drawer Hloov Txee

 

MNS low-voltage drawer type switchgear yog nyiam los ntawm ntau lub zog engineering cov neeg siv khoom rau nws qhov zoo xws li kev saib xyuas yooj yim, ntau pab pawg tawm mus, thiab hneev taw me me. Txawm hais tias muaj ntau lub tuam txhab nyob rau hauv lub tshav pob, muaj ntau theem ntawm kev txawj ntse thiab ntau lawm ntim. Ntau lub chaw hloov me me thiab nruab nrab, vim lawv lub hauv paus kev ua haujlwm tsis muaj zog, tsis muaj kev nkag siab ntawm cov lus qhia tshwj xeeb thiab cov qauv ntsig txog cov tshuab thiab khoom siv hauv chav faib khoom. Muaj kev pheej hmoo ntawm kev tsim thiab kev teeb tsa ntawm cov tub rau khoom thiab cov txee hloov, ua ke nrog kev ua haujlwm tsis zoo ntawm cov neeg siv khoom thiab kev tswj xyuas, thiab kev laus ntawm cov khoom hauv cov khoom siv vim lub sijhawm ua haujlwm ntau ntxiv, Qhov no yuav ua rau muaj qhov tshwm sim ntawm high-voltage switchgear. kev xwm txheej thiab txawm tias muaj xwm txheej loj xws li kev kub hnyiab.

1. Kev ua txhaum ntau dhau

Thaum sawv ntxov Lub Xya Hli 28, 2019, MNS cov tub rau khoom qis hluav taws xob uas ua haujlwm ib txwm nyob hauv qee chav faib khoom tam sim ntawd ignited thiab ntes tau hluav taws. Txhawm rau kom tsis txhob muaj kev nthuav dav ntawm qhov tsis raug, cov neeg ua haujlwm ntawm qhov chaw ua haujlwm thiab kev tswj xyuas cov neeg ua haujlwm tau nqus cov qib siab ntawm 35kV fais fab hloov thiab nqa tawm kev tua hluav taws. Txawm li cas los xij, kev tua hluav taws tam sim ntawd tsis tau ua rau tus qauv loj tuaj yeem tua hluav taws. Nws tau txiav txim siab tias qhov qhib qhov hluav taws kub yog D28 feeder txee rau sab hauv qab siab, uas tau kub hnyiab heev thiab tau poob nws txoj haujlwm ua haujlwm. Cov txee uas nyob ib sab tsis muaj kev cuam tshuam, thiab tom qab tua hluav taws, cov nyiaj tseem ceeb tau muab tso rau hauv txoj kev khaws tseg, thiab cov nyiaj tau rov ua haujlwm dua.

Tom qab lees paub nrog cov neeg ua haujlwm nyob rau ntawm qhov chaw, chav faib khoom tau txais nyiaj txiag tag nrho thiab muab tso rau hauv kev ua haujlwm hauv xyoo 2005, thiab nws tau ua haujlwm ib txwm nyob rau lub sijhawm tsis muaj ntaub ntawv kho. Ua ntej lub tswb hluav taws kub tau los ua, qhov hluav taws xob tawm mus thiab kev thauj khoom ntawm txhua pab neeg tsis muaj qhov yuam kev, lub zog tsis ua haujlwm, lub zog tsis ua haujlwm thiab kev pib loj loj thiab kaw cov tshuab thiab cov khoom siv (cov khoom siv). Nyob rau tib lub sijhawm, kev tshuaj xyuas cov ntaub ntawv ua haujlwm tau lees paub tias peb-theem tsib xaim hloov Ammeter ntawm txhua qhov module yog qhov qub, thiab tsis muaj qhov xwm txheej thauj khoom.

 

MNS low-voltage drawer txee yog ib qho tseem ceeb ntawm cov khoom siv faib rau hauv qab siab system software ntawm chav faib khoom. Raws li qhov kev cia siab ntawm qhov kev huam yuaj no, cov chaw tsim khoom siv hluav taws xob high-voltage switchgear yuav tsum muab qhov tseem ceeb rau nws thiab nruj me ntsis ua raws li cov qauv kev lag luam hauv teb chaws rau kev tsim, tsim, thiab kev teeb tsa. Raws li cov neeg siv khoom siv hluav taws xob hluav taws xob, kev saib xyuas tsis tu ncua, kev tu, thiab kev tu vaj tse yuav tsum tau nqa tawm ntawm cov tshuab thiab cov cuab yeej siv los xyuas kom meej tias lub tshuab ua haujlwm thiab cov khoom siv ua ke.

Calibration ntawm MNS 1 module tub rau khoom txee fais fab hloov tom qab shunt disconnection:

Drawer txee fais fab hloov

1. Tom qab lub ntsiab fais fab hloov (molded case circuit breaker) nyob rau hauv lub outgo module ntawm pab pawg neeg yog disconnected vim yog ib qho kev ua txhaum, lub koom haum ua haujlwm tiag tiag lub qhov rooj kov tseem nyob rau hauv "Å" (rov qab) txoj hauj lwm.

1. Sab saum toj ntawm lub module (tub rau khoom txee), lub koom haum rov qab lub qhov rooj kov (nyob rau hauv qhov opposite direction) yuav tsum tig mus rau 45 degree RESET txoj hauj lwm nyob rau hauv qab sab laug ces kaum, thiab ces lub qhov rooj kov (clockwise) yuav tsum tig mus rau " ○ "(kaw) txoj hauj lwm. Thaum lub sijhawm no, qhov kev rho tawm hloov pauv rov qab mus rau qhov chaw nqus dej ib txwm muaj (nyob rau hauv rooj plaub ntawm qhov kub standby) rau calibration thiab kev ua haujlwm tiag tiag.

2. Qhov kev ua haujlwm tiag tiag ntawm kev rov qab tuaj yeem tsuas yog ua tau tom qab lub calibration tau ua tiav.
