VARISTOR WITH FAST THERMAL PROTECTION

The invention refers to a varistor featuring a fast shutdown of source voltage when the heating of the varistor reaches the critical overheating level and consequentially destruction. The varistor with fast thermal protection which includes the flat-shaped varistor body (1), an upper electrode (6), a lower electrode (2), a varistor enclosure (18) and a varistor enclosure cover (3) differs from any state of the art applications by the fact that the thermal disconnector is attached to the varistor body by way of conductive glue, which creates a link reacting extremely fast to any elevated temperature of the varistor body and use of pouring mass with an improved heat transmission compared to the currently applied pouring masses and is non inflammable thus providing a secondary protection against excessive heating, burning and destruction of the varistor. The thermal protection according to the invention enables a faster disconnection in the case of exceeding the critical body temperature of the varistor compared to state of the art solutions providing an excellent link between the varistor body which is warming up and the thermal disconnector. The varistor with fast thermal protection can also switch the signalisation for emergency situation signalling made with the signalisation connector (24) consisting of a signalization connector bearing (4) and plug of the signalization connector (5). Predmetni izum razkriva varistor z lastnostjo hitrega odklopa izvora napetosti, ko segrevanje telesa varistorja doseže kritično mejo pregrevanja in posledično uničenja. Varistor s hitro termično zaščito. ki vključuje telo varistorja ploščate oblike (1), zgornjo elektrodo (6), spodnjo elektrodo (2), ohišje varistorja (18) in pokrov ohišja varistorja (3), se od izvedb po stanju tehnike razlikuje v tem, da je termični odklopnik na telo varistorja. pritrjen s pomočjo termično prevodnega lepila, kar ustvarjapovezavo, ki izjemno hitro reagira na povišanje temperature telesa varistorja in uporabo zalivne mase, ki bolje odvaja toploto od do sedaj uporabljenih zalivnih mas in je negorljiva in s tem zagotavlja sekundarno zaščito pred pretiranim segrevanjem, gorenjem in uničenjem varistorja. Termična zaščita po izumu omogoča hitrejši odklop v primeru prekoračitve kritične temperature telesa varistorja glede na stanje tehnike z izvirno povezavo med telesom varistorja, ki se segreva in termičnim odklopnikom. Varistors hitro termično zaščito lahko vključuje tudi signalizacijo za javljanj
