Incazelo Emfushane:

I-Impulse Voltage Test System isetshenziselwa ikakhulukazi ukukhiqiza i-lightning impulse voltage, ukucwaninga nokuhlola ikhono le-lightning impulse yemishini kagesi. Ingakhiqiza i-standard lightning waveform kanye ne-chopping waveform. Lesi simiso singasetshenziselwa ukuhlolwa kwe-impulse voltage kanye nolunye ucwaningo lwesayensi nge-GIS, ikhebula, ama-insulator, i-air gap, i-bushing, ama-transformer njll.

Isimo Sokusetshenziswa

• Ukuphakama: ≤1000M

• Izinga lokushisa lemvelo: -20℃-40℃. Ukwehluka okukhulu kwezinga lokushisa: 25℃

• Umswakama wemvelo: umswakama ohlobene ≤75% (Ngemva kokuba indawo yokuvikela isomile, ijeneretha ingasetshenziswa ngokujwayelekile)

• Amandla okumelana nokuzamazama komhlaba: ≤ikilasi 8.

• Indawo: Ngaphakathi

• Amandla amakhulu kagesi: 380V izigaba ezintathu izingcingo ezine, izigaba ezimbili ≥20kVA

• I-voltage yokulawula: 220V, isigaba esisodwa ≥5kVA.

• I-waveform ye-power supply voltage iyisine wave, izinga lokuhlanekezela kwe-waveform lingaphansi kuka-3%, i-frequency ingu-50Hz, futhi uhlangothi lwe-power supply akufanele luthole i-overvoltage evela ngaphandle.

• Kufanele kube nendawo yokuxhuma phansi ethembekile, igridi yamandla okuxhuma phansi kufanele ibe nezici ezinhle zomthelela, ukumelana nokuxhuma phansi akufanele kube ngaphezu kuka-0.5Ω esimweni esizinzile.•

Imingcele Eyinhloko Yezobuchwepheshe

• I-voltage ebizwa ngegama: ±900kV

• Amandla akaliwe: 90kJ

• I-impulse capacitance: 0.1µF

• I-voltage yesigaba ebizwa ngegama: ±150kV

• Inani leSigaba: 6

• Amandla esigaba esikalisiwe: 15kJ

• Amandla esigaba esikalisiwe: 1.33µF

• Izinga lephutha lokuvumelanisa: ≤1%

• I-voltage encane yokuphuma: ≥15%Un

• Ama-waveform resistors anikezwa, angalungiswa ngokusekelwe kumthwalo.

• Isimo se-impulse voltage kanye nokusebenza kahle

I-standard lighting wave: isikhathi se-wave head: 1.2±30µs, isikhathi se-wave tail: 50±20%µs

Uma i-positive ne-negative polarity lightning shock wave ingenalutho, i-voltage utilization coefficient ingu-≥90%.•

I-standard lightning chopping wave: isikhathi se-wave head: 1.2±30%µs, isikhathi sokunqamuka: 3-6µs.

l Nge-Glaninger circuit, ukulawulwa okusizayo kwisekhethi ye-low-voltage kulingana ne-high-voltage wave modulation resistor ukuthuthukisa i-waveform.

I-voltage ekhokhelwayo: 100kV.
I-Capacitance: 2000pF.
Inani le-resistor: 0.1/0.2/0.5Ω ama-current resistors, angashintshwa
