Isiguquli Sokushintsha Esimaphakathi Nesiphezulu Sokuguqula Amandla: Umhlahlandlela Wobuchwepheshe

(Kusekelwa yiDatha kanye namazinga emboni)

​1. Imisebenzi Eyinhloko kanye Nendima Yemboni​

I-Switchgear isebenza njengomgogodla wezinhlelo zamandla kagesi ophakathi nophezulu (i-MV/HV), yenza imisebenzi emithathu ebalulekile kuma-transformer:

• ​Ukusatshalaliswa Kwamandla: Ihambisa ugesi kusuka kuma-transformer kuya emithwalweni ngokusebenzisa ama-feeder, ama-busbar, namadivayisi okuvikela.
• ​Ukuvikelwa Kwephutha: Iphazamisa amaphutha emifudlaneni ngaphakathi kwama-millisecond (isb., amandla okuphuka kwe-short-circuit angu-31.5kA–40kA) ukuvimbela umonakalo wemishini.
• ​Ukuhlukaniswa Kokuphepha: Iqinisekisa ukulungiswa okuphephile ngokusebenzisa izingidi zokuxhumanisa kanye nezindlela zokufaka isisekelo.

Isibonelo, uhlelo lwe-12kV ludinga indawo encane ukusuka phansi iye phansi engu-125mm (efakwe umoya) noma engu-40mm (efakwe igesi) ukuvimbela ukugoba

.

​2. Izinhlobo kanye Nomklamo Wesakhiwo​

Ukuhlukaniswa kwe-Switchgear kanye nokucaciswa okubalulekile:

​Izingxenye Ezibalulekile:

• ​I-Vacuum Circuit Breaker (VCB)​: Inikeza imisebenzi engaphezu kuka-10,000 yemishini enokumelana nokuxhumana okungu-
• ​Amabhari ebhasi: Ama-conductor ethusi noma e-aluminium (ahlanganisa izingxenye ≥100×10mm²) anokuqina kokushisa okufika ku-40kA/4s.
• ​Ukudluliselwa Kokuvikela: Amadivayisi ahambisana ne-IEC 61850 okuthola i-overcurrent, i-differential, kanye ne-arc-flash.

​3. Imininingwane Yobuchwepheshe kanye Nezindinganiso​

• ​Izilinganiso ze-Voltage:

• I-MV: 3.3kV–36kV (evame kakhulu kumagridi ezimboni).
• I-HV: 66kV–800kV (amanethiwekhi okudlulisa).
  • ​Amazinga Okuvimbela Ukushisa:

• ​Izici Zokuphepha:

• ​Ama-Interlocks amahlanu Okuvimbela: Kuvimbela ukunikezwa kwamandla ngengozi (isb., amaswishi okuvula umthwalo awakwazi ukuvala ngaphandle kokuthi ama-circuit breaker avuliwe).
• ​Ukukhululeka Ekucindezelekeni: Amaphaneli angaqhumi (isb., i-aluminium engu-0.8mm) amagesi omoya angena ku-≤50kPa ukuvikela opharetha.

​4. Iziqondiso Zokukhetha Nokunakekela​

• ​Ukukhetha Okuqhutshwa Uhlelo Lokusebenza:

• ​Izindawo Zamanje Ezinephutha EliphezuluSebenzisa i-SF6-insulated GIS ukuze uthole amandla e-dielectric athuthukisiwe.
• ​Izindawo EzinzimaKhetha izivalo ezinesilinganiso se-IP54 ezinezimbozo ezingagqwali.
  • ​Ukuhlolwa Okuvamile:
• ​Ukumelana Nokuxhumana: ≤100μΩ (kukalwa nge-micro-ohmmeter).
• ​Ukuhlolwa Kwe-Dielectric: 1.2/50μs lightning impulse (±10% ukubekezelelana).
• ​Ukuqina Kwemishini: Imisebenzi engaphezu kuka-5,000 yama-circuit breakers.

​5. Izitayela Ezivelayo​

1. ​Ukwenziwa kwedijithali:

• I-Smart switchgear ihlanganisa izinzwa ze-IoT zokuqapha izinga lokushisa ngesikhathi sangempela, ukudlidliza, kanye nokukhishwa okuyingxenye.
• Isibonelo: Ipulatifomu ye-EcoStruxure kaSchneider Electric ivumela ukulungiswa kokubikezela ngokusebenzisa ukuhlaziywa kwamafu.
  2. ​Ukusimama:
• Ezinye izindlela ezingenayo i-SF6 (isb., i-vacuum noma i-solid-insulation) zinciphisa ukukhishwa kwamagesi okushisa ngo-95%.
  3. ​Umklamo We-Modular:
• Amakhabhinethi axhumanisa futhi adlale (isib. i-UniGear ZS1 ye-ABB) afinyeza isikhathi sokufaka ngo-40%.
