Ekukhanyeni kwesitalato, oku sele kubonakala kwizixeko ezininzi, kodwa imeko ikwenyuka kwimizi-mveliso nakwizibane zokwakha. Nangona kunjalo, nalapha kuyacaca ukuba kukho amacala omabini alula nawomthunzi.

Kwiminyaka yakutshanje, kuye kwabonakala ukuba i-voltages ezigqithisileyo ikakhulu zimele ingxaki enkulu kwi-elektroniki ethe-ethe. Ingxelo yokuqala evela ebaleni iyakuqinisekisa oku. Isixeko sase-Esbjerg, umzekelo, sixele ukusilela okukhulu ukuza kuthi ga ngoku kwizibane zasesitratweni ezingaphezu kwama-400 ngenxa yoqhankqalazo lombane. Oku kufanelekile ukukhankanywa njengeDenmark yenye yezona ndawo zihlwempuzeke kakhulu eYurophu.

Ukubetha kombane kunokufikelela kumaxabiso aphezulu kakhulu kuxhomekeke kumgama wendawo ekuyo impembelelo, umhlaba kunye neemeko zomhlaba kunye nokuqina kombane. Umzobo 1 ubonakalisa impembelelo esemgangathweni kwiindawo zokukhanya kwezibane zasesitratweni ezibangelwe kukwenziwa kwefaneli enokubakho kwisitrayikhi sombane.

Ngexesha lokutshintsha kwemisebenzi kwinethiwekhi, iincopho zeevolthi ezingamawaka aliqela ziveliswa, ezisasazeka kwinethiwekhi yamandla asezantsi kunye nokulayisha ezinye izixhobo.

Umzekelo oqhelekileyo kukukhubeka kweefyuzi okanye iinethiwekhi ezixubeneyo kunye ne-LED kunye nezibane eziqhelekileyo zokukhupha ezineebhalastri eziqhelekileyo, ezibonelela ngamawaka eetvts zombane.

Imirhumo ye-Electrostatic yinto eyenzeka ngokukodwa kwimeko yoKhuselo lodidi lwe-Luminaires apho ukwahlulwa kwentlawulo kwenzeka emva koko kubanevolthi ephezulu kwindlu yezikhanyiso okanye isinki yobushushu be-LED. Le nto ngumceli mngeni wokwenene kubo bonke abaqhubi bemoto. ngubani, xa ebamba imoto yakhe, ngamanye amaxesha unokufumana umothuko wombane.

Ukuchaphazeleka ngokukodwa zizikhanyiso ezisebenza zodwa zodwa emhlabeni.

Iimpazamo zeempuku zingakhokelela ekuthiwa kukugcwala okwethutyana. Ukuhla kwe conductor engathathi hlangothi, umzekelo, ngenxa yomonakalo, sesona sizathu siqhelekileyo apha. Ngale mpazamo, amandla ombane anokunyuka ukuya kuthi ga kwi-400 V kwizigaba ngenxa ye-asymmetries ezinkulu kwizigaba ezi-3. Ukukhuselwa kukungagqithisi okwethutyana kufuna ingqalelo ekhethekileyo.

Kodwa kukwakho neengxaki kulwakhiwo nakwizibane zeholo. Ngokukodwa apho i-overvoltages ayiveli ngaphandle, kodwa yonke imihla ivela kwisityalo sayo. Ngokukodwa, iimeko ziyaziwa ukusuka kumzi mveliso, apho zivelisa ukugqitha kwezixhobo zombane kwaye zibangelwa ziintambo zombane ezifikelela ekukhanyeni. Ukuqala kokungaphumeleli kokukhanya okukodwa okanye ii-LEDs luphawu oluqhelekileyo loku.

Ngokusekwe kula mava, nabo, abavelisi bezikhanyiso bazifezekisile iimfuno zabo kumandla ezikhanyiso ngokuchasene neevolvingi. Amandla okomelela kwezikhanyiso zesitalato ngokuchasene nokuqhekeka kweminyaka eliqela eyadlulayo. malunga. I-2,000 ukuya kwi-4,000 V, okwangoku imalunga ne-approx. 4,000 - 6,000 V.

La mava aye akhuthaza abavelisi be-luminaire ukuba baphakamise iimfuno zabo zamandla e-luminaire ngokuchasene ne-voltages. Ngelixa kwiminyaka embalwa edlulileyo amandla ezikhanyiso zesitalato ngokuchasene neevolvingi zazimalunga. 2,000 - 4,000 V, kungoku nje. 4,000-6,000 V ngokomndilili.

Ukuthatha oku kuthathelwa ingqalelo, abavelisi abaninzi bezikhanyiso banikezela ukhetho lweeLuminaires ezinesixhobo esinamandla sohlobo 2 + 3 isixhobo sokukhusela (SPD) ukukhusela umhlaba. Ukuba oku akunakwenzeka okanye kungenjongo, umzekelo, ngenxa yokunqongophala kwendawo okanye ngenxa yokuba izibane sele zifakiwe ebaleni, i-SPD inokufakwa nakwibhokisi yefestile. inokusetyenziswa. Oku kukwabonelela ngoncedo loLondolozo olulula kunye nokuphinda usebenze kwakhona. Ukugqiba umxholo wokhuseleko kunye nokunciphisa amanqaku okukhanya. Kufuneka isongezwe ngokudibanisa uhlobo lokubamba 1 + 2 kwisitrato esitshintshayo / esasaza umbindi ngokuchasene nokusasazwa kwemibane yombane kunye neevolivingi ezikhuselweyo.

Kwinkonzo zobunjineli bokwakha, ukhuseleko olusebenzayo lunokufezekiswa ngokuxhobisa ukufakwa kombane ngombane kunye nezixhobo zokukhusela. Umzekelo, ukudityaniswa kombane kunye nohlobo lokuvalelwa kokubanjwa okungu-1 + 2 kunokusetyenziselwa ukukhusela kwimibane yombane kunye nokuhamba kwexesha eliphambili ekwakheni iindlela zokutya, kunye nohlobo lwe-SPD 2 + 3 iibhokisi zokuhambisa ukukhanya kunye neebhokisi zokudibanisa zezibane zingasetyenziselwa ukukhusela Ukudibanisa intsimi kunye nokutshintsha kweevolivingi.

Ukukhuselwa kwamandla okukhuseleka

Kukho abavelisi abaninzi bokhuseleko lokunyuka kwintengiso. Ke ngoko kufuneka isekwe kula manqaku alandelayo xa ukhetha izixhobo zokukhusela ukuhlawulwa zihlawulwe ngokukodwa.

Ukukhuselwa kwe-overvoltage elungileyo kufuneka kuvavanywe ngokwe-IEC 61643-11 kunye neemfuno zeVDE 0100-534. Ukufezekisa oku, ezi mfuno zilandelayo ziphakathi kwezinye zidibene nokubonisa imeko kwaye izixhobo zokuqhawula izixhobo zidityanisiwe kwi-SPD.

Kuba i-SPD ihlala ifihliwe kwiindawo ezingafikelelekiyo, umzekelo, kwizikhanyisi ezifakiweyo, umqondiso ococekileyo wokukhanya awulunganga. I-SPD enokukwazi ukunqamla isikhanyiso kwisekethe xa kukho isiphoso, ezi zinto zilandelayo ziyafumaneka apha indlela elungileyo nelula yokubonisa ngokungangqalanga.
