Ampacity na wire da kyauƙe

Wani alama yana kulaɗi aiki mai zurfi na abincin da suka fito da sauran voltaji mai girma 1 kV a.c. ko 1.5 kV d.c., tun daga Tafel B.52.2 zuwa B.52.13 ta IEC 60364-5-52. Yana taimakawa cewa dole na abinci ba za su zama da tsanani masu karfin jiki a lokacin rike.

Bayanan Da Zaka Iya Bayyana

• Tsarin Rike: Daga IEC 60364-5-52 (Tafel A.52.3), kamar a fata, a kan duct, a kan duwatsu, baya. Nau'i: Babu duk tsari suna samun takarda a kan ruwan masu mu'amala.

• Abubuwan Abinci: Kopper (Cu) ko Aluminum (Al), wanda ke tabbatar da gaba-gaban da kyau ga jiki

• Tsarin Jiki:

• Thermoplastic (PVC): Tsanani ma'adoni 70°C

• Thermosetting (XLPE ko EPR): Tsanani ma'adoni 90°C

• Maidadi na Abinci (mm²): Masa na abinci

• Jiki Na Ingantaccen Kasa: Jiki na kasa a lokacin da ya shiga:

• Shaida na jiki na hawa: IEC 60364-5-52 Tafel B.52.14

• Shaida na jiki na tsaye: IEC 60364-5-52 Tafel B.52.15

• Shaida na jiki na tsaye: IEC 60364-5-52 Tafel B.52.16

• Miyarun Abincin Da Sake Yawan Kirkiro: Miyarun abincin da suke yawan kirkiro:

• Kirkiro mai tsawon: 2

• Kirkiro mai tsayi: 2

• Kirkiro mai biyu bayan: 2

• Kirkiro mai biyu bayan da neutral: 3

• Kirkiro mai uku bayan: 3

• Kirkiro mai uku bayan da neutral (tsayi na iya, babu harmonics): 3

• Kirkiro mai uku bayan da neutral (tsayi na ba iya ko da harmonics): 4

• Total Harmonic Distortion (THD): Miyarun harmonics 3n. Idan ba a san ba, amfani da miyarun total harmonic distortion don bayyana

• Phase Conductors in Parallel: Abincin da suka fiye za a iya haɗa; adadin da ya fi shiga ita ce sum of individual core ratings

• Circuits in the Same Conduit: Adadin circuits a kan duct na musamman wanda suke yawan kirkiro (misali, 2 lines for 2 motors). Reduction factors from IEC 60364-5-52 Table B.52.17 apply.

• Derating Factor for Parallel Cables (if present): Applies when multiple sets of cables are installed in a single duct. Each set includes: one conductor per phase + single neutral (if required) + single protective conductor.

Amsa

• Aiki mai zurfi mai girma (A)

• Rarrabe na jiki na ingantaccen kasa

• Shaida na miyarun circuits

• Shaida na harmonics

• Standards: IEC 60364-5-52, Tables B.52.2–B.52.13

An gina shi don mafi girman electrical engineers and designers don zabi abincin da suka fito da jiki masu karfi da kuma tsaro da rike, domin taimakawa rike da tsaro da koyarwa.
