Isivikeli se-SPD sokusekela T1 uchungechunge
Ukuhlolisisa umkhiqizo
Ngokuya ngamazinga we-GB18802.1, GB50057 kanye ne-Q/THQBOO1-2013, umkhawulo wangaphambili we-SPD loop kufanele uhlanganiswe ngokulandelana namathulusi wokuvikela ama-overcurrent atlhogwa mkhiqizi we-surge protector.
Ngombana i-fuse yamanje kanye ne-scuit breaker encani angeze yakghona ukusebenzisana ne-SPD, lokha umthombo wamandla ungakajayeleki nofana i-SPD nayiwohloka begodu yehluleka, umlilo nemitjhini ilinyazwa ngumbani, okuthinte khulu ukusebenza okujayelekileko kokukhiqiza!
Njenganje, inani elikhulu lama-breakers amancani asetjenziswa ngokubambisana ne-SPD angeze alinganiswa emaphuzwini amane alandelako:
1.I-shock yombane yamanje kulula khulu ukuyilimaza-ukuvikelwa kombane kuyabhalelwa;
2.High residual voltage umbane umfutho zamanje-ukuthembeka umbani ukuvikelwa imishini kwehliswa;
3.Ifrikhwensi yamandla yamahhala ayikhubeki-umthombo wamandla awukajayeleki begodu i-SPD ivutha umlilo;
4.Umbane utjhabalala ngephutha-ukuvikelwa kombani kuyabhalelwa.
Ngokuya ngobujamo bamanje bokuthi ayikho i-SPD-ekhethekileko esekela isivikelo sokuvikela umbani, ngemva kweminyaka emithathu yokurhubhulula nokuthuthukisa kanye neminyaka engaphezu kweyodwa yokulinga okuhlukahlukeneko kokulingisa ibhoduluko elabhorethri, kufakazelwe bona i-SPD backup protector (SCB)
1.SPD amandla wefrikhwensi yokutjhaphuluka inani lokukhamba 4A
2.Non-trip impulse current mkhulu kune-40kA(8/20);
3.Ukugandeleleka okusaleleko. Rarulula ngokupheleleko ubujamo bamanje bokuthi i-SPD ayinawo amathulusi akhethekileko wokuvikela ngamandla amakhulu; Umphumela oqondileko wokubambisana hlangana ne-SCB ne-SPD kuqinisekisa bona i-SPD ayibambi umlilo begodu umthelela wombane awukhubeki.
Umsebenzi nobubanzi bokusetjenziswa
I-SPD ekhethekileko yangaphandle yokukhipha ixhunywe ngochungechunge ku-SPD iluphu, begodu idivayisi yangaphakathi yokuhlunga isiteshi samanje isetjenziselwa ukufezekisa amandla wefrikhwensi encani yamanje yokuphumula okurhabako; Umbane omkhulu wamanje awukhubeki. Ukufezekisa umsebenzi wamandla wefrikhwensi encani yamanje SPD ukuvikelwa komlilo kanye nombani umthelela SPD ukuvikelwa okuragela phambili; Imikhiqizo ye-SCB isetjenziselwa ukuvikela i-SPD loop, nofana ukuvikela i-backup yamanje. Sibawa ungazisebenzisi kezinye iinkhathi.
Isici somkhiqizos
1. Indlela yokukhubeka elawulwa yipharamitha, engenza ukuphuka okukhethiweko kwamanje;
2. Ivoltheji eseleko ye-impulse current iphasi, engafaniswa neyefuzi;
3. Ukuthintana kwamandla amakhulu, okunesikhathi eside sokuphila;
4. Ijamo eliphukileko elincani, ivolumu encani, elungele ukwehluleka kwamandla ukuthola i-SPD;
5.Imininingwana epheleleko, ukuhlangabezana neemfuneko zokusekela i-SPD emazingeni we-T1, T2 kanye ne-T3.
Ukufakwa kwe-clamp rail ye-6.35mm kuhlangabezana neendingo zokufakwa ephasini loke.
