Khoom Description

GGD 3 Theem Tsawg Voltage Fixed Mounted Hluav Taws Xob Switchgear yog siv rau lub teeb pom kev zoo, lub zog hloov pauv, kev faib tawm thiab kev tswj hwm rau AC tis system nrog ntsuas zaus 50HZ thiab ntsuas kev ua haujlwm voltage 380V, ntsuas tam sim no mus txog 3150A ntawm fais fab nroj tsuag, substation, kuv cov lag luam thiab lwm yam. cov neeg siv.

3 Theem Tsawg Voltage Tsau Mounted Hluav Taws Xob Switchgear muaj peev xwm tawg siab, ntsuas lub sijhawm luv luv tiv thaiv tam sim no tuaj yeem ncav cuag 50KA, kev teeb tsa hluav taws xob hloov pauv tau yooj yim thiab kev sib txuas yooj yim thiab lwm yam. Nws yog ib qho ntawm cov khoom raug rau cov khoom sib sau ua ke, tsau vaj huam sib luag switchgear hauv domestic.

3 Theem Tsawg Voltage Tsau Mounted Hluav Taws Xob Switchgear ua raws li lub teb chaws tus qauv GB7251 Tsawg-voltage Switchgear thiab Cov Khoom Siv Tswjhwm, tus qauv thoob ntiaj teb IEC 60439 Tsawg-voltage Switchgear thiab Cov Khoom Tswjhwm.

Ib puag ncig puag ncig:

1) Ib puag ncig kub: -5 degree ~ +40 degree

2) Qhov siab: Tsawg dua lossis sib npaug li 2000m

3) Cov av noo txheeb ze: Tsawg dua lossis sib npaug li 90% (+25 degree)

Thiab tus txheeb ze av noo yuav tsum tsis txhob ntau tshaj 5% thaum lub siab tshaj plaws kub yog 40 degree. Ib tug txheeb ze humidity loj yog tso cai nyob rau hauv ib tug qis kub. Tej zaum yuav muaj qee zaus condensation vim qhov hloov ntawm qhov kub thiab txias

4) Kev teeb tsa: Tsis muaj kev vibration hnyav thiab poob siab, Tsis muaj corrosion
