Qalabka korantada ee fiilooyinka sawir-qaadista

2024-11-19

1. DC caabbinta


Iska caabinta DC ee xudunta conductive ee la dhammeeyeyfiilo sawir lehat 20 ℃ kama badna 5.09Ω/km.


2. Tijaabada korantada biyaha immersion


Fiilada dhammaatay (20m) waxaa lagu dhex milmay (20± 5) ℃ biyaha 1h ka dibna waxaa la mariyaa tijaabada 5min ee danab (AC 6.5kV ama DC 15kV) iyada oo aan la burburin.


3. Iska caabinta korantada DC ee muddada-dheer


Muunadu dhererkeedu waa 5m waxaana lagu dhex ridayaa biyo nadiif ah oo ay ku jiraan 3% sodium chloride (NaCl) at (85±2)℃ ee (240±2) h, iyadoo labada darafba ay u bannaan yihiin oogada biyaha ilaa 30cm. Danab DC ah oo ah 0.9kV ayaa la mariyaa inta u dhaxaysa xudunta iyo biyaha (xuddunta korantada waxay ku xiran tahay tiirka togan, biyuhuna waxay ku xiran yihiin tiirka taban). Ka dib marka muunada la qaado, waxaa la sameynayaa tijaabada korantada biyaha immersion, korontadu waa AC 1kV, wax burbur ah looma baahna.


4. Iska caabin dahaarka


Iska caabbinta dahaarka ee fiilada sawir-qaadista ee dhammaatay ee 20 ° C waa inuusan ka yarayn 1014Ω · cm,


Caabbinta dahaarka ee fiilada la dhammeeyey ee 90°C waa in aanu ka yarayn 1011Ω·cm.


5. caabbinta dusha galka


Iska caabbinta dusha sare ee galka fiilada la dhammeeyey waa inuusan ka yarayn 109Ω.
