Ukulanda kwamahhala Amazinga we-BS EN IEC weDivayisi Yokuvikela Yokuvikela (SPD)

Ama-SPD ethu ukuhlangabezana nemingcele yokusebenza echazwe kumazinga we-International & European:

  • I-BS EN 61643-11 Amadivayisi wokuvikela axhumeke kumasistimu wamandla we-low-voltage - izidingo nokuhlolwa
  • I-BS EN 61643-21 Yenyuka amadivayisi wokuvikela axhunywe ezokuxhumana ngocingo nokusayina amanethiwekhi - izidingo zokusebenza nezindlela zokuhlola

Lezi zingxenye zezinga le-BS EN 61643 zisebenza kuwo wonke ama-SPD ahlinzeka ngokuvikelwa emibani (eqondile nengacacile) kanye nama-voltages wesikhashana.

I-BS EN 61643-11 ifaka ukuvikelwa kwama-AC mains, ama-50/60 Hz AC power circuits nemishini elinganiselwe ku-1000 VRMS AC naku-1500 V DC.

I-BS EN 61643-21 ihlanganisa ezokuxhumana ngocingo nokusayina amanethiwekhi anama-voltages wesistimu yokuqamba aze afike ku-1000 VRMS AC naku-1500 V DC.

Ngaphakathi kwalezi zingxenye ezisezingeni kuyachazwa:

  • Izidingo zikagesi zama-SPD, kufaka phakathi ukuvikelwa kwamandla kagesi namazinga wamanje wokukhawulela, inkomba yesimo nokusebenza okuncane kokuhlolwa
  • Izidingo zemishini yama-SPDs, ukuqinisekisa ikhwalithi efanelekile yokuxhuma, nokuzinza kwemishini lapho kufakwa
  • Ukusebenza kokuphepha kwe-SPD, kufaka phakathi amandla ayo womshini kanye namandla ayo okumelana nokushisa, ukumelana ngokweqile kanye nokumelana nokuqina

Izinga lisungula ukubaluleka kokuhlola ama-SPD ukuthola ukusebenza kwawo kagesi, okwenziwa ngemishini nokuphepha.

Ukuhlolwa kukagesi kufaka ukuqina kwempoqo, ukukhawulelwa kwamanje, kanye nokuhlolwa kokudluliswa.

Ukuhlolwa kwemishini nokuphepha kusungula amazinga okuvikelwa ekuxhumaneni ngqo, amanzi, umthelela, imvelo efakiwe ye-SPD njll.

Ngokwe-voltage nokusebenza kwamanje okukhawulela, i-SPD ihlolwa ngokuya ngohlobo lwayo (noma i-Class to IEC), echaza izinga lombani wamanje noma wevoltage edlulayo kulindeleke ukuthi ikhawulele / iphambukise kude nemishini ebucayi.

Ukuhlolwa kufaka phakathi amandla okukhishwa kwamanje we-Class I, Class I & II modinal discharge current, Class I & II voltage impulse kanye ne-Class III test wave wave for SPDs ezifakwe ezintanjeni zikagesi, kanye no-Class D (energy high), C (rate fast of rise), kanye no-B (isilinganiso esinyukayo sokukhuphuka) kwalabo abakwimigqa yedatha, yesiginali neyezingcingo.

Ama-SPD ahlolwa ngokuxhumeka noma ukunqanyulwa kokulandela imiyalo yomkhiqizi, njengokufakwa okulindelekile kwe-SPD.

Izilinganiso zithathwa ezixhumi / ezikhumulweni. Amasampula amathathu e-SPD ahlolwa futhi konke kumele kudlule ngaphambi kokuthola imvume.

Ama-SPD ahlolwe ku-BS EN 61643 kufanele afakwe ilebula efanele futhi amakwe, ukufaka idatha yokusebenza efanele yohlelo lwabo lokusebenza.

Imininingwane Technical

Ngaphakathi kwe-BS EN 61643 kunemininingwane emibili yezobuchwepheshe enikeza izincomo ngokukhethwa nokufakwa kwama-SPD.

Lezi izi:

  • I-DD CLC / TS 61643-12 Yakha amadivayisi wokuvikela axhunywe kumasistimu wamandla we-low-voltage - imigomo yokukhetha neyokusetshenziswa
  • I-DD CLC / TS 61643-22 Yakha amadivayisi wokuvikela axhunywe ezokuxhumana ngocingo nokusayina amanethiwekhi - imigomo yokukhetha nokusetshenziswa

Lokhu Ukucaciswa Kwezobuchwepheshe kufanele kusetshenziswe ne-BS EN 61643-11 ne-BS EN 61643-21 ngokulandelana.

Ukucaciswa ngakunye Kwezobuchwepheshe kunikeza imininingwane nokuholwa ku:

  • Ukuhlolwa kobungozi nokuhlola isidingo sama-SPD kumasistimu anamandla amancane, ngokubhekisele kwi-IEC 62305 standard standard protection protection kanye ne-IEC 60364 Electrical ukufaka izakhiwo
  • Izici ezibalulekile ze-SPD (isb. Izinga lokuvikelwa kwamandla) ngokuhlangana nezidingo zokuvikela imishini (isb. Umfutho wayo ukumelana noma ukuzivikela komzimba)
  • Ukukhethwa kwama-SPD kucatshangelwa yonke imvelo yokufaka, kufaka phakathi ukuhlukaniswa kwabo, ukusebenza nokusebenza
  • Ukudidiyelwa kwama-SPD kukho konke ukufakwa (kwamandla nolayini bedatha) naphakathi kwama-SPD nama-RCD noma amadivayisi wokuvikela angaphezulu kwamanje

Ngokulandela ukuqondiswa okukule mibhalo, ukucaciswa okufanele kwama-SPD ukuhlangabezana nezidingo zokufaka kungafinyelelwa.

Thayipha i-1, 2, noma i-3 SPDs ku-BS EN / EN 61643-11 ifana ne-Class I, Class II kanye ne-Class III SPDs ne-IEC 61643-11 ngokulandelana.

Ukuqwashisa, ukuthi ama-surges esikhathi esidlule angumthelela omkhulu we-MTBF (Isikhathi Esiphakathi Kokwehluleka) kwezinhlelo nemishini, kushayela bonke abakhiqizi endaweni yokuvikelwa kokuqhuma ukuthi baqhubeke ngokuqhubekayo nokwakha amadivayisi amasha wokuvikela ukuvota anezici ezandayo futhi ngokuhambisana nalokho amazinga omhlaba nawaseYurophu.
