Abstract
The utility model relates to a voltage-sensitive module device which comprises a voltage-sensitive resistor component and an elastic electrode. Because a heat-sensitive tripping device is arranged on a protruding arm of the voltage-sensitive resistor component, an alarm system is arranged on the periphery of the heat-sensitive tripping device and comprises an interlock switch and an alarm port device. When a current passing through a voltage-sensitive resistor increases, the voltage-sensitive resistor is heated, and heat is transferred to the heat-sensitive tripping device through a heat-collecting electrode; when a set temperature is reached, the heat-sensitive tripping device acts, and the elastic electrode is separated from the heat-collecting electrode under the function of the elastic stress of the elastic electrode so as to cut off a current and prevent the voltage-sensitive resistor from being continuously heated to cause a fire; and simultaneously, the elastic electrode triggers a dynamic-off switch to switch off and triggers a dynamic-on switch to switch on and output two groups of alarm signals. When a short circuit fault of the voltage-sensitive resistor occurs or an impact current exceeds the bearing capability of the voltage-sensitive resistor, the heat-sensitive tripping device arranged on the elastic electrode switches off so as to prevent the voltage-sensitive resistor from burning out the device and due to short circuit and exploding due to overload, and simultaneously, the elastic electrode triggers the dynamic-off switch to switch off and triggers the dynamic-on switch to switch on and output two groups of alarm signals.
