Wani Proximity Effect?

Tsari: Idan maɗauki masu kwayoyin hawa suka shiga tsarin karamin kwayoyi, karamin kwayoyin su ne ba da shirya a cikin tsari. Wannan alamun ya zama a kan abin da ake kiran mafi yawan karamin kwayoyi. Alamar mafi yawan karamin kwayoyi yana haifar da tsarin karamin kwayoyi saboda tattalin masu karamin kwayoyi a cikinsu.

Idan maɗaukin karamin kwayoyi biyu ko kadan suna cikin yadda aka fi sani, mutanen kalubale masu kafofin su ne suka haifar da karamin kwayoyi. Saboda wannan haifar, karamin kwayoyi a cikin maɗauki na karamin kwayoyi ne ke samun yawan karamin kwayoyi a kusa da maɗauki na karamin kwayoyi.

Idan maɗauki na karamin kwayoyi suna karamin kwayoyi a cikin yadda aka fi sani, kalubale masu kafofin maɗaukinta suna shiga karamin kwayoyi. Saboda haka, babu karamin kwayoyi wanda ya shiga waɗannan maɗaukinta, amma karamin kwayoyi suna gudanar a cikin maɗauki na karamin kwayoyi da ba su da shirya.

Idan maɗauki na karamin kwayoyi suna karamin kwayoyi a faduwar yadda aka fi sani, kalubale masu kafofin maɗaukinta suna haifar da karamin kwayoyi a cikin maɗaukinta. Amma, kalubale masu kafofin maɗaukinta da ba su da shirya suna shiga karamin kwayoyi. Saboda haka, karamin kwayoyi suna gudanar a cikin maɗauki na karamin kwayoyi da su da shirya, amma maɗauki na karamin kwayoyi da ba su da shirya suna da karamin kwayoyi mai yawa.

Idan DC ta shiga maɗauki, karamin kwayoyi ta shiga tsari a cikin maɗauki da shirya. Saboda haka, babu alamar mafi yawan karamin kwayoyi a cikin maɗauki.

Alamar mafi yawan karamin kwayoyi yana da muhimmanci don maɗauki masu tsari da yake da 125 mm². Don haka, ana buƙata a yi amfani da sakamakon sahihi.

Idan an yi amfani da alamar mafi yawan karamin kwayoyi, AC resistance ta shiga:

Alamomin:

• Rdc: Uncorrected DC resistance of the conductor.

• Ys: Skin effect factor (the fractional increase in resistance due to the skin effect).

• Yp: Proximity effect factor (the fractional increase in resistance due to the proximity effect).

• Re: Effective or corrected ohmic resistance of the conductor.

DC resistance Rdc za a iya samun daga taulukan maɗauki masu karamin kwayoyi.

Muhimman Muhimmancin Alamar Mafi Yawan Karamin Kwayoyi

Alamar mafi yawan karamin kwayoyi yana da muhimmanci don muhimman abubuwa kamar abincin maɗauki, tsari, kwayoyi, da kuma tsari. Wannan abubuwa suna bayyana a nan:

• Kwayoyi – Alamar mafi yawan karamin kwayoyi yana haifar da kwayoyi.

• Tsari – Maɗauki masu tsari mai yawa yana haifar da alamar mafi yawan karamin kwayoyi.

• Tsari – Wannan alam yana da muhimmanci a cikin maɗauki masu tsari mai yawa da maɗauki masu tsari mai yawa (misali, ASCR). Maɗauki masu tsari mai yawa suna da tsari mai yawa, wanda ya haifar da karamin kwayoyi.

• Abinci – Maɗauki masu abinci mai yawan ferromagnetic suna haifar da alamar mafi yawan karamin kwayoyi saboda tattalin kalubale masu kafofin su.

Babbar Addinin Haifar Da Alamar Mafi Yawan Karamin Kwayoyi

Wannan addinin da za a iya amfani don haifar da alamar mafi yawan karamin kwayoyi shine ACSR (Aluminum Conductor Steel Reinforced conductors. A cikin maɗauki ACSR:

• Steel ta shiga a cikin tsari don bayar da inganci.

• Strands masu aluminum suna gudanar a cikin steel core, wanda ya shiga cikin tsari masu karamin kwayoyi.

Wannan tsari ya haifar da tsari mai yawa wanda ake shiga tattalin kalubale masu kafofin su. Saboda haka, karamin kwayoyi suna gudanar a cikin aluminum layers, amma steel core ba suna shiga karamin kwayoyi. Wannan tsari ya haifar da alamar mafi yawan karamin kwayoyi a cikin maɗauki.
