Khoom Taw qhia
ZN{1} Kev tsim thiab tsim khoom ntawm cov khoom no ua raws li JB6463-92 "Technical Conditions for Circuit Breakers Siv nyob rau hauv Electrified Railways".
ZN 42-27.5 railway-specific nqus Circuit Court beaker yog tsim rau electrified railway fais fab mov systems nrog ib tug rated voltage ntawm 27.5kV thiab ib-theem AC 50Hz, thiab nws ua hauj lwm raws li ib tug tshwj xeeb mus rau tawg / ua load thiab tawg. txhaum tam sim no. Nws tuaj yeem ntsia tau ib tus zuj zus nyob rau hauv ib qho kab sib txuas lossis txuas rau hauv JYN-27.5 switchgear. Kev khiav hauj lwm mechanism ntawm cov khoom no yog lub caij nplooj ntoos hlav lub zog cia hom. Nws tuaj yeem ua hluav taws xob los ntawm AC lossis DC lub zog, lossis ua haujlwm ntawm tes.

Khoom zoo
ZN 42-27.5 railway-specific lub tshuab nqus tsev twj tso kua mis muaj ntau yam zoo:
01
Kev ua haujlwm ntawm Circuit Court breaker
E2-C2-M2
02
Kev saib xyuas yooj yim
lub modular mechanism tsim tso cai rau hloov tau yooj yim ntawm lub kaw thiab qhib coils yam tsis tas yuav dismantling lwm yam khoom. Qhov no tshem tawm qhov kev xav tau ntawm kev sim lossis kev hloov kho tom qab hloov pauv, ua kom cov neeg siv hloov lawv tus kheej, ua rau kev saib xyuas tom qab tau yooj yim dua.
03
High conductivity kev ua tau zoo
lub ntsiab conductive circuit adopts lub tshuab nqus tsev interrupter, muab lub neej ntev hluav taws xob.
04
Txhawb kev txawj ntse customization
nws tuaj yeem tsim tshwj xeeb nrog cov cuab yeej saib xyuas online txhawm rau txhim kho kev ruaj ntseg.
Cov khoom siv
Cov khoom yog tsim tshwj xeeb rau electrified railway fais fab mov systems,
siv rau kev tawg / ua haujlwm thiab rhuav tshem tam sim no.
