Please refer to FIG. 1, which shows a top view and a view of a known surge absorber. As shown in the figure, the conventional surge absorber includes:-an oxide J, which has a conductive layer 7 on each of the upper and lower sides, and is welded on the electrode surface 7 (generally tin-plated copper wire) 8 and is coated on the outer layer Epoxy powder is used for insulation, insulation, and moisture resistance. Its working principle is to use the grain boundary phenomenon of the zinc oxide ceramic sheet ^ to protect the instantaneous overvoltage that occurs at both ends, and use the wave energy in a thermal manner. It is necessary to generate electricity when it works, and it must flow through the body of the ceramic chip 6 to convert the surge energy into a heat form. Please refer to FIG. 2, which shows a schematic diagram of a conventional use of a surge absorber to protect the L-N-G two-wire power supply. As shown in the figure 'Traditionally, a surge absorber is used to protect the L-N_G three-wire power supply. For instantaneous overvoltage (surge energy) between L-N-G, three independent surges are usually required. The absorber 9 can be completely protected, in which each surge absorber 9 independently completes the protection between the two lines.
