    8.1 Protezione contro le correnti di cortocircuito

    Le condutture devono essere protette contro le sovracorrenti.

    Gli interruttori automatici TemBreak, magnetotermici o con dispositivo di protezione a microproces-sore, assicurano sia la protezione contro il sovraccarico che la protezione contro il cortocircuito.

    Le grandezze da considerare per coordinare conduttura e interruttore automatico sono:

    - corrente di impiego del circuito IB,- portata della conduttura Iz,- corrente nominale dell'interruttore (o di regolazione) In,- potere di interruzione dell'interruttore Icu/Ics,- integrale di Joule dell'interruttore I2t,- integrale di Joule del cavo K2S2.

    La protezione contro le correnti di cortocircuito è assicurata quando l'interruttore ha un potere di interruzione non inferiore alla corrente di cortocircuito presunta nel punto di installazione e interviene in un tempo non superiore a quello che porta i conduttori (il loro isolante) alla temperatura limite ammissibile.

    E' quindi indispensabile calcolare la corrente di cortocircuito. Nel seguito sarà supposta nota perchè il suo calcolo esula dallo scopo del presente documento.

    Nel seguito è analizzata la seconda delle condizioni sopra riportate a cui deve rispondere l'interruttore automatico affinchè assicuri la protezione del cavo (il suo isolante) contro il cortocircuito:

    I2t < K2S2

    cioè, il valore dell'energia termica lasciata passare dall'interruttore durante un cortocircuito deve essereminore del valore che puo sopportare l'isolamento del cavo affinchè non si danneggi.

    I è la corrente effettiva di cortocircuito (A),t è la durata del cortocircuito (s),K è la costante dell'isolamento del cavo,S è la sezione del conduttore (mm˝).

    Oltre alla riduzione degli effetti termici della corrente di cortocircuito, nel seguito è analizzata lacondizione affinchè siano ridotti anche gli effetti elettrodinamici.

    8.2 Integrale di Joule del cavo - K2S2

    Valori della costante K per conduttori in rame:

    - 115 isolamento in PVC,- 143 isolamento in gomma etilenpropilenica e propilene reticolato.

    I valori massimi ammissibili dell'integrale di Joule (K2S2, in 106A2s), per correnti di cortocircuito maggiori di 1kA, risultano:

    185 452,625 699,867

    240 761,760 1.177,862

    I valori sopra riportati devono risultare maggiori dell'energia specifica passante (Let-trough energy) lasciata passare dall'interruttore.

    8.3 Integrale di Joule dell'interruttore - I2t2

    Al presente documento sono allegate le curve dell'integrale di Joule (I2t, in 106A2s) degli interruttori scatolati TemBreak in funzione della corrente di cortocircuito (Icc, in kA).

    Per una data corrente di cortocircuito, il valore (I2t) letto sul grafico deve essere confrontato con il valore (K2S2) riportato nella precedente tabella, per una data sezione e per un dato isolante.

    Se risulta minore il cavo è protetto per quel valore di corrente di cortocircuito.

    Se risulta maggiore è necessario aumentare la sezione del cavo.

    8.4 Corrente di picco - Ip

    Gli effetti elettrodinamici delle correnti di cortocircuito sono particolarmente pericolosi per i condottisbarre, ma possono arrecare danni anche ai cavi.

    In assenza di interruzione il valore di picco Ip della corrente di cortocircuito dipende dalla corrente dicortocircuito Icc, dal fattore di potenza di cortocircuito cosϕcc, dall'angolo di inserzione del cortocircuitoψ. Nel caso peggiore il rapporto Ip/Icc vale circa 2,2. Cioè, per effetto della componente unidirezionaleil valore di picco della prima semionda è circa il 56% maggiore del valore di picco della componentesimmetrica.

    L'interruttore automatico TemBreak introduce, dopo il tempo di prearco, una resistenza d'arco cheimpedisce, fin dalla prima semionda, il raggiungimento del valore di picco sopra considerato (inassenza di interruzione), limitandolo. L'effetto di limitazione è dovuto al ridotto tempo di prearco eall'elevata tensione d'arco grazie al Fast Break Mechanism basato su speciali camere spegniarco,contatti a doppia repulsione e conduttori a U.

    Al presente documento sono allegate le curve di limitazione del valore di picco della corrente dicortocircuito (Ip, in kA) degli interruttori scatolati TemBreak in funzione della corrente di cortocircuitostessa (Icc, in kA).

    Per una data corrente di cortocircuito, è il valore della corrente di picco letto sul grafico che deve essereutilizzato per i calcoli delle sollecitazioni elettrodinamiche di una conduttura protetta da un interruttoreautomatico TemBreak.
