Matsayin Manyan Abubuwa da Kayan Amsa don SPD (Surge Protective Devices) a Fannin Amfani

SPDs (Surge Protective Devices) suna samun wasu manyan abubuwa a fannin amfani na gida:

• Yadda kadan tsohon lamarin (Uc) yana cikin hanyar wata ita ce mai yawa a kan jirgin kuli;

• Yadda kadan takardun ingantattun (Up) yana fiye da yadda kadan takardun inganci (Uw) na kayan aiki;

• Amfani da energy coordination daga baya a kan multi-stage SPDs (misali, babu koza ko staging mai yawa);

• SPDs suna yake da yawan (misali, window na bayanin halin shiga rana, alarm mai yankin an yanke) ko suka ciwo (misali, ta yi waɗanda, ta yi kusa) amma ba a yi ƙofin kowace ba;

• SPDs ba su fi sani a kan panelon distribution muhimmanci (misali, main switchboard, sub-distribution panel, front-end na kayan aiki), amma bayanan nuna ake iya (false installation);

• Tsari na kadan SPD grounding conductor yana da yawa (≥16mm² for Type I, ≥10mm² for Type II, ≥4mm² for Type III, copper conductor);

• Babu kayan amsa mai yawa (misali, fuse ko circuit breaker) an fito a kan SPD.

Wannan manyan abubuwa zai iya haɗa da matsaloli masu yawa:

• SPD ba ya iya taimakawa da yakin overvoltage daidai, wanda yake iya haɗa da kisan kayan aiki;

• SPDs da suka yake da yawan zai iya haɗa da short circuits wanda zai iya haɗa da hoton ji;

• Grounding conductors da suka yawa zai iya maza a lokacin da surge current discharge, wanda zai iya haɗa da matattaccen aiki;

• Babu kayan amsa mai yawa, fault mai short-circuit a kan SPD zai iya haɗa da hoton ji.

Don in taimaka wa SPD effectiveness da kuma matattaccen aiki, yawancin hanyoyin masu yawa su ne:

• Zaɓe SPDs daidai da tsarin takarda na kayan aiki da kuma wurin a kan (misali, lightning protection zones LPZ0–1, LPZ1–2), kuma taimaka wa energy coordination daidai a kan SPD stages;

• Fitar da SPDs daidai a wurin power inlet na kayan aiki;

• Amsa SPDs da suke da status indicators ko remote alarm functions;

• Bayyana program mai nuna da kuma ƙofin kowace kasa a kan SPDs;

• Tabbatar da tsari na grounding conductors da kuma taimaka wa hubbin daidai;

• Koyar da kayan amsa mai yawa a kan SPDs.
