I-SPD yokusekela umvikeli we-T2 uchungechunge

Ukuhlolisisa umkhiqizo

Ngokuya ngamazinga we-GB18802.1, GB50057 kanye ne-Q/THQBOO1-2013, umkhawulo wangaphambili we-SPD loop kufanele uhlanganiswe ngokulandelana namathulusi wokuvikela amandla aphezulu atlhogwa mkhiqizi we-surge protector. Ngombana i-fuse yamanje ne-miniature circuit breaker angeze yakwazi ukusebenzisana ne-SPD, lokha i-powerpp ihluleka ngokungakajayeleki, i-SPD umlilo nemitjhini ilinyazwe ngumbane, okuthinte khulu ukusebenza okujayelekileko kokukhiqiza!

Njenganje, inani elikhulu lama-breakers amancani asetjenziswa ngokubambisana ne-SPD angeze alinganiswa emaphuzwini amane alandelako:

 

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 bokusetjenziswan

 

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.

 

Iimfanelo zomkhiqizo

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.
