Abstract
A protection cover used for avoiding the influence brought about by the temperature effect of a varistor is proposed. The protection cover is made of ceramic or refractory material, and is used to bear high temperature generated when a metal oxide varistor breaks down to catch fire and to further cover the fire therein, thereby preventing the fire from burning out application components around the metal oxide varistor. Moreover, accommodation portions and grooves for receiving temperature breakers are disposed on the protection cover to provide a better contact surface between the protection cover and the temperature breakers so that the temperature breakers can more accurately detect the temperature on the protection cover, hence reducing the occurrence of the situation of erroneous actions.
