1 термическая неустойчивость ОПН
термическая неустойчивость ОПН
Состояние, при котором выделяющаяся в ОПН мощность превышает его способность рассеивания тепла, что приводит к росту температуры ограничителя, потере его тепловой стабильности и разрушению.

thermal runaway of an arrester
situation when the sustained power loss of an arrester exceeds the thermal dissipation capability of the housing and connections, leading to a cumulative increase in the temperature of the resistor elements culminating in failure

emballement thermique d'un parafoudre
situation où la puissance absorbée de façon prolongée par un parafoudre dépasse la capacité de dissipation de l'enveloppe et des connexions, et conduit à une augmentation cumulative de la température des varistances qui se termine par une défaillance du parafoudre
