beskyttelse – til problemfrie forløb på hospitaler.
Et omhyggeligt planlagt overspændingsbeskyttelseskoncept er en central del af lynbeskyttelsen og især af stor betydning for medicinske faciliteter som hospitaler. Især skal der tages hensyn til påvirkningen fra direkte og indirekte lynnedslag. Fordi elektriske og elektroniske systemer på hospitalet er livsnødvendige for patienterne. Da de samtidig er en del af de stadigt mere avancerede digitaliseringsprocesser, er det afgørende, at disse systemer fungerer pålideligt. Med overspændingsbeskyttelse sikrer du, at farlige interferensenergier reduceres til et acceptabelt niveau, så de ikke længere udgør en fare.

Sådan planlægger du den korrekte overspændingsbeskyttelse til hospitaler.
Lynbeskyttelsespotentialudligningen spiller en særlig vigtig rolle i bygninger med udvendigt lynbeskyttelsessystem. Dette skal udføres for alle ledende systemer, der kommer ind i bygningen udefra, iht. EN 62305-3. Endvidere skal et EMC-baseret lynbeskyttelseszonekoncept iht. EN 62305-4 til beskyttelse af følsomme komponenter tages i betragtning.
Overspændingsbeskyttelsesenheder underinddeles i lynstrømsafledere, overspændingsafledere og kombiafledere. Der stilles de højeste krav til afledningsevnen på lynstrøms- og kombiafledere, der realiserer overgangen fra lynbeskyttelseszone 0A til 1 eller 0A til 2. Disse afledere skal være i stand til at føre lyndelstrømme i bølgeformen 10/350 μs uden problemer for at forhindre, at ødelæggende lyndelstrømme trænger ind i en bygnings elektriske anlæg.
Ved overgangen fra lynbeskyttelseszone 0B til 1 (eller nedstrøms for lynstrømsaflederen ved overgangen fra lynbeskyttelseszone 1 til 2 og derover) anvendes der overspændingsafledere til beskyttelse mod overspændinger. Det er deres opgave yderligere at reducere de foranliggende beskyttelsestrins restspænding samt at begrænse de overspændinger, der induceres i anlægget eller genereres der.
