Abstract
The invention discloses a lightening protection module and a lightening protection device comprising the lightening protection module. The lightening protection module comprises a voltage dependent resistor (10) and a discharge tube (20). The voltage dependent resistor (10) and the discharge tube (20) are connected in series. The lightening protection module further comprises a first thermal fuse (30) which is connected with the voltage dependent resistor (10) and the discharge tube (20) in series and is arranged adjacent to the voltage dependent resistor (10) and the discharge tube (20). The first thermal fuse (30) is fused when the temperature is beyond a preset value. After the lightening protection module is connected with the first thermal fuse in series, when the temperature of the voltage dependent resistor or the discharge tube is too high, the first thermal fuse is also too high in temperature and fused to disconnect a circuit to avoid a fire hazard. The first thermal fuse allows large currents to pass through, so that it is guaranteed that the lightening protection module can normally work under the condition that the voltage dependent resistor and the discharge tube are at a normal working temperature.
