Tsawg-voltage switchgear txais tus qauv tsim qauv. Modularization yog ib daim ntawv ntawm standardization tsom rau versatility. Rau kev rho tawm tsawg-voltage switchgear, modular tsim yog siv rau hauv cov qauv tsim. Modular tsim txhais tau tias txiav txim siab ib qho yooj yim module (piv txwv li, E=20mm lossis 25mm), thiab qhov ntev ntawm lub txee ncej thiab nws qhov mounting qhov, qhov chaw ntawm cov chaw ua haujlwm, thiab qhov loj me ntawm cov khoom siv (cov tub rau khoom lossis cov ntu txuas txuas ntxiv) yog tag nrho cov nce lossis txo raws li qhov xav tau ntawm cov lej ntau ntawm cov qauv yooj yim. Rau kev tshem tawm tsawg-voltage switchgear, tag nrho qhov chaw txais cov qauv qhov ntev, thiab qhov ntev ntawm qhov chaw ua haujlwm (drawers) kuj tau tsim modularly, kom txhua chav haujlwm ua haujlwm nyob hauv qhov chaw hexahedral raws li kev sib xyaw ua ke.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm low-voltage air circuit breakers (low-voltage circuit breakers)) yog siv cov thermal expansion thiab dabtsi yog khoov ntawm bimetallic sawb los ua ib tug lever, ua rau lub Circuit Court breaker mus txawv tebchaws thiab muab kev tiv thaiv overload. Thaum ib qho kev sib tsoo dav dav tshwm sim hauv Circuit Court, qhov overload tam sim no tsim cov cua sov hauv cov cua sov, ua rau lub bimetallic strip khoov thiab thawb lub zog, disengaging lub latch thiab rhuav lub ntsiab tiv tauj los txiav tawm lub hwj chim. Thaum ib qho luv luv Circuit Court lossis overload hnyav tshwm sim, luv luv -circuit tam sim no tshaj qhov tam sim no mus txawv tebchaws teeb tsa tus nqi tam sim no. Lub tshuab electromagnetic mus txawv tebchaws tsim kev nyiam, kos lub armature thiab ntaus lub zog, ua rau lub latch tig upwards nyob ib ncig ntawm lub pivot thiab disengage ntawm lub latch. Lub latch, nyob rau hauv qhov kev txiav txim ntawm lub caij nplooj ntoos hlav rov qab, lov lub ntsiab tiv tauj, txiav tawm lub hwj chim. Lub tripping mechanism ntawm kev hloov yog ib qho khoom siv txuas. Thaum cov kev sib cuag tseem ceeb raug kaw, lawv raug kaw hauv qhov chaw kaw los ntawm lub latch. Yog hais tias muaj teeb meem tshwm sim nyob rau hauv lub Circuit Court, qhov chaw mus txawv tebchaws yuav qhib, ua rau lub latch nyob rau hauv lub tripping mechanism disengage, thiab lub ntsiab kev sib cuag yuav sai sai tawg nyob rau hauv qhov kev txiav txim ntawm lub caij nplooj ntoos hlav tso tawm. Muaj peb hom tripping txoj kev: thermal, electromagnetic, thiab ua ke tripping.
"Air" hauv kev hloov pauv huab cua yog hais txog kev sib cuag qhib thiab kaw hauv huab cua ntawm atmospheric siab. Nws arc-kev tua hluav taws muaj xws li cov yam ntxwv tsis zoo ntawm DC arcs, qhov "zero-so" tshwm sim ntawm AC arcs, ze rau - cathode nyhuv, thiab txoj kev xws li kab sib chaws arc extinguishing thiab magnetic blowout arc extinguishing.
Lub arc-kev tua hluav taws yog qhov tseem ceeb rau kev txhim kho kev ua haujlwm tawg ntawm cov hluav taws xob hluav taws xob. Lub arc tshiab -tshuaj tua hluav taws siv lub arc zoo li qub- cais npog thiab arc dynamic- cais npog nrog arc- cais tawm los muab kev tiv thaiv rwb thaiv tsev rau kev txav mus los thiab chaw nres tsheb sib txuas, txo qis kev ua tsis tiav los ntawm arc overflow thiab txhim kho arc peev xwm -
Shenheng Power's patented low-voltage switchgear siv lub kav dej thiab ob lub kiv cua rau kev sib koom ua ke cua sov dissipation, tsim ib tug multi-layer airflow distribution network thiab peb-dimensional heat dissipation field los daws cov teeb meem ntawm qhov tsis sib xws ntawm cov cua sov dissipation hauv ib txwm hloov pauv.
