Izi zalimbikitsanso opanga ma luminaire kuti akweze zofunikira pazowunikira pamagetsi. Pomwe zaka zingapo zapitazo mphamvu ya magetsi oyenda mumsewu motsutsana ndi ma overvoltages anali pafupifupi. 2,000 - 4,000 V, pakadali pano pafupifupi. 4,000 - 6,000 V pafupifupi.

Pofuna kukumbukira izi, opanga ma luminaire ambiri amapereka ma Luminaires okhala ndi chida champhamvu cha Type 2 + 3 (SPD) choteteza dziko. Ngati izi sizingatheke kapena mwadala, mwachitsanzo chifukwa chakuchepa kwa malo kapena chifukwa zowunikira zili kale m'munda, SPD itha kukhazikitsidwanso mu bokosi la mast fuse. angagwiritsidwe ntchito. Izi zimapindulitsanso mwayi wa Kukonzanso kosavuta komanso kupanganso zina. Kuti mumalize lingaliro lachitetezo ndikuchotsa zowunikira. Iyeneranso kukhala ndi zida zogwirizira zophatikizira 1 + 2 mu switchgear / Central distributor motsutsana ndi kufalikira kwa mphezi ndi zotuluka zotetezedwa.

Pakumanga zomangamanga, chitetezo chokwanira chitha kupezeka mwakukhazikitsa makina amagetsi ndi mphezi ndi zida zotetezera. Mwachitsanzo, mphezi ndi mafunde omwe amamangirira amtundu wa 1 + 2 atha kugwiritsidwa ntchito poteteza mafunde amagetsi ndi maimidwe apansi pakumanga chakudya, ndipo SPD yamtundu wa 2 + 3 mabokosi opatsira magetsi ndi mabokosi olumikizirana amagetsi angagwiritsidwe ntchito poteteza kuphatikiza kwam'munda ndikusintha kwazinthu zambiri.

Chitetezo chokwanira chokwanira

Pali opanga ambiri omwe amateteza chitetezo pamsika. Chifukwa chake ziyenera kukhazikitsidwa ndi mfundo zotsatirazi posankha zida zodzitetezera zizisamalidwa mwapadera.

Chitetezo chabwino chobisalira chiyenera kuyesedwa malinga ndi IEC 61643-11 ndi zofunikira za VDE 0100-534. Kuti izi zitheke, zofunikira izi ndi zina mwazomwe zidakwaniritsidwa ndikuwonetsa zida zophatikizika zimaphatikizidwa mu SPD.

Popeza SPD nthawi zambiri imabisidwa m'malo osafikika, mwachitsanzo, ma luminaires amaikidwa, kuwonetsa kopanda tanthauzo sikokwanira. SPD yomwe imatha kutsegulanso zowunikira kuchokera mdera likakhala ndi vuto, zotsatirazi zikupezeka apa njira yabwino komanso yosavuta yosonyezera molunjika.

Tekinoloje ya LED ikukhala yofunika kwambiri pakuunikira. Ukadaulo wowonjezera umatsimikizira mayankho odalirika. Zoyeserera, zolimbitsa thupi zomwe zimasungidwa ndi malingaliro otetezera zimasokoneza zamagetsi zomwe sizingachitike. Zowonjezerapo za lingaliro loyenera la chitetezo chokwanira pamayendedwe owunikira pakadali pano ndi ochepera gawo limodzi la ndalama zonse. Njira zotetezera kupitilira muyeso ndizofunikira kwa aliyense wogulitsa mbewu. zosavuta komanso nthawi zambiri njira zofunikira pakuonetsetsa kuti moyo wautali utha kukhala wodalirika komanso kuwunika kwa magetsi ndikupewa mtengo wotsatira.

Mfundo zowonjezera zowonjezera zamagetsi oyatsa mumsewu a LED

Ukadaulo wa LED wokhalitsa umatanthawuza ntchito zosamalira zochepa komanso zotsika mtengo

Magetsi akuwunika m'misewu pakadali pano akuchotsedwa ndi anthu ambiri komanso zogwiritsa ntchito mumatauni. Zowunikira wamba zimasinthidwa makamaka ndi ma LED. Chifukwa chiyani kutembenuka uku kukuchitika tsopano? Pali zifukwa zambiri: mapulogalamu othandizira ndalama, kugwiritsa ntchito mphamvu zamagetsi, kuletsa ukadaulo wina wowunikira, komanso, kukonza pang'ono pazowunikira za LED.

Chitetezo chabwino chaukadaulo wokwera mtengo

Teknoloji ya LED ili ndi zabwino zambiri. Komabe, imakhalanso ndi chitetezo chochepa kwambiri kuposa matekinoloje wamba owala. Kuphatikiza apo, zowunikira za LED ndizokwera mtengo m'malo mwake. Mwachizolowezi, kuwunika kowonongeka kwawonetsa kuti ma surges nthawi zambiri amawononga magetsi opitilira XNUMX mumsewu nthawi imodzi.

• Pewani kulephera
• Phatikizani Chitetezo Chokwera

Zowonongeka zomwe zimachitika chifukwa cha ma surges atha kukhala kulephera pang'ono kapena kwathunthu kwa gawo la LED, kuwonongeka kwa driver wa LED, kutaya kuwala kapena kulephera kwamagetsi onse.

Ngakhale nyali ya LED ikupitilizabe kugwira ntchito, ma surges nthawi zambiri amakhala ndi vuto pa moyo wake wothandizira.

Pewani ntchito zosamalira zosafunikira ndikusamala kupezeka ndi lingaliro lachitetezo cha bespoke surge.
