    摘要: A surge absorbing device of composite construction comprising a high resistance element of metal oxide and a pair of electrodes connected to the high resistance element with a discharging gap formed between the electrodes. At a normal state, a fine current flows through the high resistance element, but when a surge voltage is transiently applied across the high resistance element, a triggering discharge is produced across the electrodes by a voltage drop of the product of the resistance value of the high resistance element and the value of surge current whereby it is immediately transferred to a main discharge of large current to absorb the surge current at a high velocity. A heat-proof and reduction-proof protective film is formed on the surface of the high resistance element to stabilize the characteristic of surge absorption. The protective film may be formed of a carbide of a carbon group element, of lead borosilicate glass or deleaded glass, or of a multi-layer of lead borosilicate glass or deleaded glass and metal oxide.
