Tsim lub hauv paus ntsiab lus ntawm hluav taws xob rhaub
PTC hluav taws xob rhaub module muaj PTC cua sov Cheebtsam, controllers thiab sab hauv pipelines. Cov cua sov tivthaiv tau muab tso rau hauv aluminium tuag casting, aluminium tuag casting thiab cov yas casing tsim ib qho kev kaw cov raj xa dej, thiab cov kua dej txias ntws los ntawm lub cev cua sov hauv cov qauv me me.
Kev tswj hluav taws xob yog ib qho txhuas tuag-cam khwb cia lub cev npog nrog cov hlau casing. Cov maub los Circuit Court board yog ruaj nrog screws thiab cov connector yog ncaj qha mus rau lub rooj tsav xwm Circuit Court. Lub hauv paus ntsiab lus hluav taws xob thaiv daim duab qhia hauv daim duab 1 hauv qab no:
Daim duab 1 Hluav taws xob txoj cai thaiv daim duab
Qhov siab-voltage feem yog nyob rau hauv tus ncej liab, thiab qhov qis-voltage yog sab nraum lub thav duab liab. Lub high-voltage control unit thiab low-voltage control unit muaj cov khoom siv hluav taws xob xws li microprocessors.
Qhov siab-voltage feem muaj 3 IGBTs (IGBT_A, IGBT_B, IGBT_C) thiab 3 pawg ntawm PTC Cheebtsam (PTC_A, PTC _B, PTC_C) los ua 3 qhov hluav taws xob hluav taws xob cua sov, uas tuaj yeem ua rau nws tus kheej qhib lossis tawm. Kev tswj hwm lub zog ib kauj ruam tuaj yeem ua tiav los ntawm kev sib txuas, raws li qhia hauv Table 1 hauv qab no.
Chav tswj kom paub txog qhov ntsuas tam sim no thiab qhov ntsuas hluav taws xob ntawm lub voj voog high-voltage los ntawm shunt thiab sampling tsis kam feem, thiaj li paub txog kev tiv thaiv kev ua haujlwm txawv txav. Lub ntsuas kub ntsuas NTC_C yog siv los ntsuas qhov kub thiab txias ntawm PCB thiab tiv thaiv nws thaum lub sijhawm kub siab dhau.
Muaj TVS ntawm lub hwj huam mov inlet ntawm qhov tsawg-voltage ib feem kom zoo tiv thaiv surges. Lub high-frequency rho tawm transformer yog siv los muab lub zog pab rau sab high-voltage. Kev sib txuas lus cov ntaub ntawv yog sib pauv ntawm cov high- thiab low-voltage tswj units los ntawm digital isolators. Nrog lub zog-wired wake-up muaj nuj nqi, nws tuaj yeem paub txog kev sawv thiab pw tsaug zog. Input auxiliary fais fab mov ib feem tam sim no txwv kev tiv thaiv muaj nuj nqi. Qhov ntsuas kub ntsuas NCT_A thiab NTC_B nyob ntawm qhov dej nkag thiab qhov hluav taws xob raws li tau siv los txheeb xyuas qhov ntsuas kub ntawm cov dej txias hauv lub sijhawm tiag tiag thiab tiv thaiv nws lub sijhawm thaum kub siab dhau. .
