\u010caute chlapi, vitajte na blogu MJM Automation, s.r.o.<\/p>\n\n\n\n

Ak ma u\u017e trochu pozn\u00e1te, viete, \u017ee elektrika<\/strong> pre m\u0148a nie je len o tom natiahnu\u0165 k\u00e1bel od bodu A do bodu B a \u00eds\u0165 domov.<\/p>\n\n\n\n

Bav\u00ed ma, kam sa technol\u00f3gie pos\u00favaj\u00fa, a komer\u010dn\u00e1 fotovoltika (FVE) v priemysle je presne to miesto, kde sa dnes l\u00e1me chlieb. Ke\u010f rob\u00ed\u0161 na z\u00e1kazk\u00e1ch vonku, najm\u00e4 v Nemecku alebo Beneluxe, r\u00fdchlo zist\u00ed\u0161, \u017ee priemyseln\u00e9 in\u0161tal\u00e1cie nad 500 kWp s\u00fa \u00faplne in\u00fd vesm\u00edr.<\/p>\n\n\n\n

Dnes chcem vypichn\u00fa\u0165 jednu absol\u00fatne k\u013e\u00fa\u010dov\u00fa vec, ktor\u00e1 odli\u0161uje majstrov od za\u010diato\u010dn\u00edkov pri obrovsk\u00fdch stre\u0161n\u00fdch a parkoviskov\u00fdch FVE: Po\u017eiarno-bezpe\u010dnostn\u00e9 odp\u00e1ja\u010de a kritick\u00fd mana\u017ement sp\u00e1jania stringov<\/a>.<\/strong><\/p>\n\n\n\n

Ke\u010f ti na streche le\u017eia stovky stringov<\/h2>\n\n\n\n

Pri in\u0161tal\u00e1ci\u00e1ch na rodinn\u00fdch domoch (ni\u010d proti „dom\u010dek\u00e1rom“, ka\u017ed\u00fd nejako za\u010d\u00ednal) zvedie\u0161 dva-tri stringy do strieda\u010da a m\u00e1\u0161 hotovo. Ale predstav si logistick\u00e9 centrum s obrovskou rovnou strechou a v\u00fdkonom 1 MWp. Tu u\u017e operujeme s mas\u00edvnymi pr\u00fadmi a obrovsk\u00fdmi d\u013a\u017ekami DC tr\u00e1s.<\/p>\n\n\n\n

Spr\u00e1vne dimenzovanie DC k\u00e1blov<\/a> a sp\u00e1janie stringov tu u\u017e nie je len o tom, aby „to fungovalo“, ale aby si predi\u0161iel obrovsk\u00fdm \u00fabytkom nap\u00e4tia a, \u010do je najd\u00f4le\u017eitej\u0161ie, riziku po\u017eiaru. Pri tak\u00fdchto v\u00fdkonoch sa ak\u00e1ko\u013evek chyba v prechodovom odpore na DC strane prejav\u00ed extr\u00e9mne r\u00fdchlo a brut\u00e1lne.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Po\u017eiarnici na z\u00e1pade ti neodpustia ani milimeter<\/h2>\n\n\n\n

To, na \u010dom mnoh\u00e9 partie pri prechode na ve\u013ek\u00e9 komer\u010dn\u00e9 projekty pohoria, s\u00fa po\u017eiarno-bezpe\u010dnostn\u00e9 odp\u00e1ja\u010de (tzv. Fireman Switches<\/a>). Ke\u010f m\u00e1\u0161 na hale obrovsk\u00e9 strieda\u010de s v\u00fdkonom 100 kW a viac, po\u017eiarna bezpe\u010dnos\u0165 je na prvom mieste<\/a>.<\/p>\n\n\n\n

Z\u00e1padn\u00e9 normy (ku ktor\u00fdm sa dostaneme v \u010fal\u0161\u00edch \u010dl\u00e1nkoch) s\u00fa v tomto nekompromisn\u00e9. Akon\u00e1hle vypukne v hale po\u017eiar, hasi\u010di musia ma\u0165 istotu, \u017ee po zhoden\u00ed hlavn\u00e9ho isti\u010da nezostane na DC vedeniach vo vn\u00fatri budovy smrtiace nap\u00e4tie.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Ako k tomu pristupujeme v praxi?<\/h2>\n\n\n\n

Odp\u00e1ja\u010de sa musia strategicky in\u0161talova\u0165 v tesnej bl\u00edzkosti panelov<\/strong>, ide\u00e1lne hne\u010f pri vstupe DC trasy do budovy alebo priamo pod strechou, e\u0161te predt\u00fdm, ne\u017e trasa prejde cez po\u017eiarne \u00faseky<\/a>. Tieto zariadenia automaticky preru\u0161ia DC obvod, akon\u00e1hle stratia AC nap\u00e1janie zo siete.<\/p>\n\n\n\n

Ich mont\u00e1\u017e a zapojenie si vy\u017eaduje absol\u00fatnu presnos\u0165. Mus\u00ed\u0161 presne vedie\u0165, ako rozvrhn\u00fa\u0165 stringy, aby si neprekro\u010dil maxim\u00e1lne povolen\u00e9 nap\u00e4tie a pr\u00fad samotn\u00e9ho odp\u00e1ja\u010da, a z\u00e1rove\u0148 mus\u00ed\u0161 dokonale zvl\u00e1dnu\u0165 k\u00e1blov\u00fd mana\u017ement. Trasy k odp\u00e1ja\u010dom musia by\u0165 veden\u00e9 v \u0161peci\u00e1lnych chr\u00e1ni\u010dk\u00e1ch, \u010dasto s vysokou po\u017eiarnou odolnos\u0165ou.<\/p>\n\n\n\n

Je to pr\u00e1ca, ktor\u00e1 \u0165a n\u00fati prem\u00fd\u0161\u013ea\u0165 dopredu. Mus\u00ed\u0161 ma\u0165 v hlave nielen sch\u00e9mu zapojenia, ale aj fyzick\u00e9 rozlo\u017eenie na tej obrovskej ploche, aby \u0165a potom na konci d\u0148a neprekvapilo, \u017ee ti ch\u00fdba 50 metrov \u0161peci\u00e1lneho k\u00e1bla, alebo \u017ee si odp\u00e1ja\u010d umiestnil do z\u00f3ny, kam hasi\u010di v Nemecku pod\u013ea noriem v\u00f4bec nebud\u00fa chcie\u0165 \u00eds\u0165.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Si pripraven\u00fd na vy\u0161\u0161iu ligu?<\/h2>\n\n\n\n

Prechod z mal\u00fdch striech na tieto priemyseln\u00e9 giganty je to najlep\u0161ie, \u010do m\u00f4\u017ee\u0161 pre svoju kari\u00e9ru elektrik\u00e1ra urobi\u0165. Je to pr\u00e1ca, kde sa skuto\u010dne cen\u00ed odbornos\u0165, kde prich\u00e1dza\u0161 do styku s top technol\u00f3giami a mas\u00edvnymi syst\u00e9mami.<\/p>\n\n\n\n

Ak \u0165a tak\u00e1to v\u00fdzva l\u00e1ka a m\u00e1\u0161 u\u017e pln\u00e9 zuby sk\u00e1kania po mal\u00fdch \u0161ikm\u00fdch strech\u00e1ch rodinn\u00fdch domov, v MJM Automation neust\u00e1le h\u013ead\u00e1me \u0161ikovn\u00fdch chlapov \u2013 \u017eivnostn\u00edkov<\/a>, ktor\u00ed chc\u00fa robi\u0165 na stabiln\u00fdch a profi projektoch v zahrani\u010d\u00ed.
