Nebudeme sa tu bavi\u0165 o legislat\u00edve, certifik\u00e1toch na mediplyny, farb\u00e1ch trubiek, ani o tom, pre\u010do mus\u00edte ma\u0165 \u0161peci\u00e1lne BOZP. To s\u00fa otrepan\u00e9 t\u00e9my, ktor\u00e9 u\u017e m\u00e1 ka\u017ed\u00fd zrel\u00fd \u017eivnostn\u00edk v mal\u00ed\u010dku (a ak n\u00e1hodou nie, u n\u00e1s v MJM-AUTOMATION v\u00e1m s tou byrokraciou radi helfneme).<\/p>\n\n\n\n

Jasn\u00e9, pri in\u0161tal\u00e1cii mediplynov mus\u00edme natiahnu\u0165 aj klasick\u00fd silnopr\u00fad pre kompresorovne<\/a>, zapoji\u0165 v\u00e1kuov\u00e9 pumpy, rie\u0161i\u0165 k\u00e1blov\u00e9 trasy v \u0161acht\u00e1ch a d\u00e1va\u0165 si bacha na to, aby sme netrasovali silov\u00e9 k\u00e1ble hne\u010f ved\u013ea meden\u00fdch rozvodov kysl\u00edka. Ale to spom\u00ednam len na okraj, lebo pre n\u00e1s, vyjazden\u00fdch elektrik\u00e1rov, je toto len be\u017en\u00e1 dr\u00f4tova\u010dka.<\/p>\n\n\n\n

Dnes si vezmeme pod lupu nie\u010do, z \u010doho maj\u00fa mnoh\u00ed re\u0161pekt, no ak to zvl\u00e1dne\u0161, si na stavbe za frajera: Elektrick\u00e1 integr\u00e1cia a zbernicov\u00e9 zapojenie z\u00f3nov\u00fdch uzatv\u00e1rac\u00edch ventilov (AVSU) a ich signaliza\u010dn\u00fdch panelov v priestoroch kateg\u00f3rie 2.<\/a><\/strong><\/p>\n\n\n\n

Pre\u010do sa do tohto detailu v\u0155tam tak hlboko?<\/h3>\n\n\n\n

Zd\u00f4vodn\u00edm ti to \u00faplne jednoducho. Presne tu sa toti\u017e l\u00e1me chlieb medzi „be\u017en\u00fdm \u0165aha\u010dom k\u00e1blov“ a top \u0161pecialistom, ak\u00fdch v MJM-AUTOMATION sprostredk\u00favame. Zatia\u013e \u010do obrovsk\u00fd kompresor medzistienkou je v podstate len hl\u00fapy motor, AVSU panel priamo pred opera\u010dnou s\u00e1lou<\/a> (alebo na JISke) je ten najkritickej\u0161\u00ed uzol. Je to bod, kde sa stret\u00e1va na\u0161a elektrika s absol\u00fatne kritickou pneumatikou. Ak tu, ako elektrik\u00e1r na \u017eivnos\u0165, sprav\u00ed\u0161 chybu v tienen\u00ed, zbernici alebo v posp\u00e1jan\u00ed, pri commissioning-u (o\u017eivovan\u00ed) bude syst\u00e9m h\u00e1dza\u0165 chybov\u00e9 hl\u00e1\u0161ky, ktor\u00e9 bude\u0161 h\u013eada\u0165 t\u00fd\u017ede\u0148. Alebo e\u0161te hor\u0161ie \u2013 priamo ohroz\u00ed\u0161 pacienta na s\u00e1le.<\/p>\n\n\n\n

Tak\u017ee, ako na to, aby to klaplo na prv\u00fdkr\u00e1t?<\/p>\n\n\n\n

1. Anal\u00f3gov\u00e9 slu\u010dky a ru\u0161enie od meni\u010dov<\/h3>\n\n\n\n

Tlak v syst\u00e9moch (kysl\u00edk, stla\u010den\u00fd vzduch, rajsk\u00fd plyn) sa z potrubia meria tlakov\u00fdmi prevodn\u00edkmi, ktor\u00e9 id\u00fa do alarmov\u00e9ho panela. Naj\u010dastej\u0161ie sa stretne\u0161 s pr\u00fadov\u00fdmi slu\u010dkami 4-20 mA. Tieto k\u00e1ble (\u010dasto typu J-Y(St)Y alebo lep\u0161ie LiYCY<\/a>) musia by\u0165 pr\u00edsne tienen\u00e9. Zlat\u00e9 pravidlo:<\/strong> Tienenie uzem\u0148ujeme z\u00e1sadne len na jednom konci<\/em> (ide\u00e1lne na strane panelu\/centr\u00e1ly). Ak to ukostr\u00ed\u0161 aj na paneli, aj na kostre potrubia, vytvor\u00ed\u0161 par\u00e1dnu zemn\u00fa slu\u010dku. Indukovan\u00e9 bludn\u00e9 pr\u00fady z okolit\u00fdch pr\u00edstrojov ti rozhasia hodnoty a panel za\u010dne nezmyselne p\u00edska\u0165, \u017ee pad\u00e1 tlak kysl\u00edka, hoci je potrubie natlakovan\u00e9.<\/p>\n\n\n\n

2. D\u00e1tov\u00e9 zbernice (RS-485 \/ CAN) a topol\u00f3gia<\/h3>\n\n\n\n

AVSU panely nie s\u00fa ostrovy \u2013 musia komunikova\u0165 s centr\u00e1lnym vel\u00ednom a technikmi \u00fadr\u017eby. V 90 % pr\u00edpadov tu \u0165ah\u00e1me RS-485 alebo Modbus RTU<\/a>. Zabudni na hviezdu, \u0165ah\u00e1\u0161 striktn\u00fa „daisy-chain“ (re\u0165az) od panelu k panelu. A \u010do je najd\u00f4le\u017eitej\u0161ie? Impedan\u010dn\u00e9 prisp\u00f4sobenie. Na posledn\u00fd panel v l\u00ednii mus\u00ed\u0161 nahodi\u0165 termina\u010dn\u00fd odpor (naj\u010dastej\u0161ie 120 ohmov). \u010eal\u0161ia vec, ktor\u00fa si ako prof\u00edk mus\u00ed\u0161 ustr\u00e1\u017ei\u0165: udr\u017euj minim\u00e1lne 20 a\u017e 30 cm odstup od silov\u00fdch tr\u00e1s (najm\u00e4 od k\u00e1blov k frekven\u010dn\u00fdm meni\u010dom vzduchotechniky). Ak mus\u00ed\u0161 kri\u017eova\u0165 silnopr\u00fad, tak v\u00fdhradne v 90\u00b0 uhle. Zaru\u0161en\u00e1 zbernica na mediplynoch je no\u010dn\u00e1 mora na odstra\u0148ovanie.<\/p>\n\n\n\n

3. Doplnkov\u00e9 ochrann\u00e9 posp\u00e1janie (VDE 0100-710 \/ STN 33 2000-7-710<\/a>)<\/h3>\n\n\n\n

Toto je t\u00e1 absol\u00fatne najd\u00f4le\u017eitej\u0161ia vec v priestoroch kateg\u00f3rie 2 (s\u00e1ly, ARO). Ka\u017ed\u00e1 jedna meden\u00e1 trubka mediplynu, ktor\u00e1 vstupuje do AVSU boxu alebo do stropn\u00e9ho zdrojov\u00e9ho mosta (pendantu) nad opera\u010dn\u00fdm stolom, mus\u00ed by\u0165 galvanicky spojen\u00e1 s lok\u00e1lnou uzem\u0148ovacou zbernicou (PA svorkovnicou) danej miestnosti. Ako elektrik\u00e1r tu nap\u00e1ja\u0161 meden\u00e9 k\u00e1ble s prierezom min. 4 mm\u00b2 (mnoh\u00e9 nemocnice v DACH regi\u00f3ne trvaj\u00fa na 6 mm\u00b2). Odpor medzi akouko\u013evek kovovou \u010das\u0165ou panelu mediplynu a PA zbernicou miestnosti mus\u00ed by\u0165 po zmeran\u00ed pod 0,2 ohmu<\/strong>.<\/p>\n\n\n\n

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

Pre\u010do je ten odpor tak\u00fd kritick\u00fd? Kv\u00f4li tzv. mikro\u0161okom. Ak m\u00e1 pacient zaveden\u00fd kat\u00e9ter priamo do srdca, vonkaj\u0161ia izol\u00e1cia ko\u017ee (ktor\u00e1 be\u017ene br\u00e1ni \u00farazu) je premosten\u00e1. V takom stave ho m\u00f4\u017ee zabi\u0165 aj pr\u00fad o ve\u013ekosti zlomkov miliamp\u00e9ra. Ak by potrubie mediplynu malo in\u00fd potenci\u00e1l ako opera\u010dn\u00fd st\u00f4l a doktor sa dotkne oboch, ten zostatkov\u00fd pr\u00fad prejde cez pacienta. My ako elektrik\u00e1ri tomu t\u00fdmto brut\u00e1lne pr\u00edsnym posp\u00e1jan\u00edm br\u00e1nime.<\/p>\n\n\n\n
