I. Core Safety Distance Specifications for Low-Voltage Cabinets
Mafambiro enzvimbo yekuchengetedzwa kweakaderera-magetsi emagetsi anonyanya kuenderana nemaitiro enyika "GB/T 7251.1-2017 Low-Voltage Switchgear uye Controlgear Assemblies" uye "GB 50054-2011 Low-Voltage Power Distribution Design Specifications." Zvakananga manhamba zvinodiwa ndezvizvi:
1. Kumberi kwechinhambwe chekushanda: Minimum 800mm (fixed cabinet) kana 1000mm (dhirowa-type cabinet), kuona nzvimbo yekushanda yakakwana yevashandi vekugadzirisa pavanenge vakagwesha kana kumira (yakataurwa kubva kuGB 50054, Chikamu 4.2.5).
2. Rear kugadzirisa kureba: Minimum 600mm, kana kanenge 800mm kana kumashure kwemukova kupinda kuchidiwa.
3. Kufara kwemukoto wepakati: Pakuronga-mitsara yakapetwa kaviri, chinhambwe chiri pakati pemakabati chinofanira kunge chiri 1000mm; kune imwe-mitsara yegadziriro pamadziro, inokwana 200mm yemvumo inofanira kusiiwa pamativi.
Zvimwe Zvinyorwa:
- Kubvisa 800mm kumberi kunobva paavhareji yemunhu mukuru anosvika kureba kwemaoko (anenge 700mm), pamwe nemvumo yekubata maturusi.
- Dhirowa-makabhati emhando anoda kumwe kucheneswa nekuti madhirowa anofanira kunge akareba.
II. Zvinodiwa Zvinodiwa Pakuchengetedzwa Kwekuchengetedza Pamusoro Pazasi-Makabati eVoltage
Kucheneswa kwedziviriro pamusoro pe-magetsi emagetsi emagetsi kazhinji haaonekwe, asi kunoisa njodzi pakubvisa kupisa uye yakakwirira-kuparadzaniswa kwemagetsi:
1. Top Clearance:
-Makabati akaderera-magetsi emagetsi: Makuru kupfuura kana kuenzana ne300mm (zvinodiwa pakudziisa);
- Kana busbar yakakwirira-yevoltage iri pamusoro pekabati: Yakakura kudarika kana kuenzana ne1200mm (inorehwa kubva muChikamu 4.3.3 cheGB 50054).
2. Kuiswa kweCable Tray Mukati meMakabati: Kana matireyi etambo akaiswa padenga rekhabhineti, chinhambwe chiri pakati petireyi yetambo nedenga recabinet chinofanira kunge chakakura kupfuura kana kuenzana ne150mm kudzivirira kupisa kupisa kusakanganisa kushanda kwemidziyo.
