ものであり、避雷器ではサージの侵入の際に装置を保護
する上で小さいことが望ましい。By the way, a nonlinear index and a limiting voltage ratio are generally used as indicators for evaluating the characteristics of a voltage nonlinear resistor. The non-linear index α is a value such that I=(V/C)', where ■ is the applied voltage, ■ is the current, and C is the amount directly equivalent to the resistance of a normal resistor (non-linear resistance). It is desirable that this nonlinear index has a large value in order to reduce the flow of current flowing through the resistor, and the limiting voltage ratio is
This is the ratio of the voltage between the terminals at the current value of the pond to the voltage VIHA between the terminals when 1 mA flows through the resistor. This limiting voltage ratio includes voltage non-linearity in a large current region, and in a lightning arrester, it is desirable that it be small in order to protect the device in the event of a surge.

招く危険がある。D0 Problems to be Solved by the Invention When used in voltage nonlinear resistors and lightning arresters manufactured by the above-mentioned conventional method, a small amount of leakage current always flows. For this reason, the resistor generates heat, and the temperature remains constant at a level that is in balance with the heat radiation. However, this type of resistor has a negative temperature coefficient in the small current range, so if it handles large energy such as continuous switching surges or lightning surges in a short period of time, or if the element itself deteriorates. In this case, the heat generated exceeds the heat dissipation capacity, the temperature rises significantly, and the leakage current flowing therein becomes excessive. If this happens, not only will power loss increase, but there will also be a condition called thermal runaway, which may lead to a short-circuit accident.

A mixed slurry is prepared by adding 0.001 to 0.05io1% of A I 2 O, which is granulated, pressure molded, and then sintered at 1100 to 1300°C. The resistor thus obtained has a large nonlinear index and a small leakage current.
従って、電力損失が少なく、戸な温度上昇が抑制される
ので、熱暴走を生じない。しかも制限電圧比が小さいの
で、サージ吸収性に優れる。Therefore, power loss is small and temperature rise is suppressed, so thermal runaway does not occur. Moreover, since the limiting voltage ratio is small, it has excellent surge absorption properties.
