More Information
Summary:The invention discloses a intelligent power source arrester, it is a trip protecting device with physical and intelligent method, it includes intelligentized embedded control system and temperature sensor, the temperature sensor is embedded into the surface of the zincite piezoresistance of the power source arrester, and insulated with the zincite piezoresistance, another temperature sensor is used to detect the temperature of entironment; the embedded CPU system can detect the parameters of power source arrester module on line, and break the poor power source arrester, the current mutual-inductor is in the trip device, it can feed back the drain current parameter of the piezoresistance to the CPU to realize the online detection of power source arrester, and judging whether the power source arrester is bad according to the set data. The cost of the invention is low, performance is reliable, the danger of self-ignite induced by bad power source arrester can be stopped, the action of trip is precise and quick, protection is in time.
