Khoom Tswj Txheej Txheem Ntawm High Voltage Coolant Rhaub 2
PTC lub rhaub dej tuaj yeem muab cua sov rau lub cockpit ntawm lub tsheb tshiab lub zog thiab ua tau raws li tus qauv ntawm kev nyab xeeb defrosting thiab defogging. Nws kuj tseem muab cov cua sov rau lwm qhov ntawm lub tsheb uas yuav tsum tau tswj qhov kub thiab txias, xws li lub roj teeb.
Tswj muaj nuj nqi
1. soft start function: PWM soft start
PWM siv 30s ntawm 0 feem pua mus rau 100 feem pua .Qhov kev ua haujlwm no yog siv los tiv thaiv cov kab hluav taws xob siab thiab kev hloov tam sim ntawm lub tsheb npav siab. Txhua channel yog maj mam pib muag, muaj ripple tam sim no nyob rau hauv cov txheej txheem muag muag, thiab cov inrush tam sim no me me (<1.3 times="" the="" rated="">
2. Txwv tsis pub muaj nuj nqi:
2.1 Kub txwv
①Thaum lub qhov hluav taws xob kub nce mus txog 80 degree, nws yuav nquag txo lub hwj chim maj mam ua kom cov dej kub ntawm qhov hluav taws xob tas li.
② Thaum qhov kub ntawm ib qho IGBT nce mus txog 85 degree, nws yuav nquag txo lub hwj chim maj mam los yog tua nws. Thaum nws qis dua 80 degree, nws yuav rov ua haujlwm, kom qhov kub ntawm IGBT tsis tshaj qhov txwv.
2.2 Lub zog txwv
Mos pib lub zog txwv: txhua lub zog tsuas yog txwv rau 2850W thaum pib muag.
3. Kev tiv thaiv muaj nuj nqi:
3.1 High voltage overvoltage thiab undervoltage tiv thaiv
Kev ua haujlwm voltage ntau tuaj yeem tsim raws li cov neeg siv khoom xav tau. Lub tshuab cua sov uas tsis nyob hauv qhov ntau yuav tsis pib lossis muab tua. Yog hais tias nws rov qab mus rau qhov ntau, nws yuav rov pib softly rau tus nqi tam sim no.
3.2 IGBT tsav voltage overvoltage thiab undervoltage tiv thaiv
Thaum lub IGBT tsav voltage tsis nyob rau hauv lub teeb ua hauj lwm ntau yam, lub cua sov yuav tsum tau muab tua kiag li, thiab tom qab rov qab, nws yuav rov pib dua softly rau tus nqi tam sim no.
3.3 Tsawg voltage tiv thaiv rov qab kev twb kev txuas tiv thaiv
Tsawg voltage rov qab txuas tsis ua haujlwm.
3.4 Qhov hluav taws xob dej kub tshaj qhov ntsuas kub tiv thaiv
Thaum cov dej kub ntawm qhov hluav taws xob siab tshaj 105 degree rau 3 vib nas this, tag nrho cov cua sov yuav raug tua tam sim ntawd.
3.5 Kev tiv thaiv luv luv
Ib qho PTC Circuit Court yog luv luv, Circuit Court yuav raug muab tua tam sim ntawd, rov kuaj xyuas 5 zaug, thiab nws tseem luv luv, Circuit Court yuav tsis muab rau cua sov ua ntej lub hwj chim dua.
3.6 Kev tiv thaiv overcurrent
Thaum lub sijhawm ua haujlwm cua sov, yog tias lub voj voog txuas ntxiv tshaj 2 npaug ntawm qhov ntsuas tam sim no rau 5s, nws raug suav tias yog overloaded, thiab Circuit Court yuav raug kaw thiab rov pib dua.
Ceeb toom:High voltage tsis muaj peev xwm tiv thaiv kev rov qab sib txuas. High voltage rov qab kev twb kev txuas yuav ua rau uncontrolled cua sov. Kev sib txuas hluav taws xob siab rov qab tuaj yeem ua rau PTC kev puas tsuaj, tuaj yeem ua rau lub tsheb tsis raug them ua ntej thiab tsis tuaj yeem pib, thiab tej zaum yuav ua rau lub precharge resistor hlawv!
