    • A heat protection device for overvoltage terminal block arrester magazines having with two-way arresters or with button arresters. According to the present invention, an S-shaped clip spring or an L-shaped clip spring is inserted in a button arrester of the 6.times.6-type or the 6.times.8-type. The clip provides one leg of the protection device having a solder preform and a switch contact to complete the circuit. In case of an overvoltage, the arc developed in the arrester causes the solder preform to melt off during an extended application of heat arising from the arrester, activating the switch contact and short-circuiting the leg of the arrester.
    • 具有双向避雷器或按钮式避雷器的过电压端子排避雷器杂志的保护装置。 根据本发明,将S形夹子弹簧或L形夹子弹簧插入6×6型或6×8型的按钮式避雷器中。 夹子提供具有焊料预制件和开关触头的保护装置的一条腿,以完成电路。 在过电压的情况下,在避雷器中产生的电弧导致焊料预成型件在延长施加由避雷器产生的热量期间熔化,激活开关触点并使避雷器的腿短路。
