Description

TECHNICAL FIELD

[0001] The utility model relates to lightning protection device security monitoring technical field especially relates to a general type intelligent lightning protection device deterioration detection device and intelligent lightning protection device. BACKGROUND

[0002] In low voltage power supply system, commonly use lightning protection device or called surge protection device, surge protection device. The traditional lightning protection device can only use remote signal interface to transmit lightning protection module disengagement (or called tripping) information to upper controller. When lightning protection module is invalid, due to the temperature of lightning protection device rises sharply and reaches a certain temperature, usually about 150 DEG C, the low temperature solder joint of lightning protection device starts to melt, the spring mechanical energy stored in the inside releases and disconnects or disengages the lightning protection device from the protection circuit. When the lightning protection module is disengaged, a micro switch on the base of lightning protection module is usually linked to release, from normally open state to normally closed state or reverse change. The change state of micro switch is transmitted to the host computer through remote signal interface. The general remote signal interface has three pins, respectively common pin, normally closed pin and normally open pin. Since the traditional lightning protection device only transmits the binary switch (0 or 1) information of whether tripping, the remote signal interface only needs two pins, common pin, normally open pin or normally closed pin, to represent the tripping state information completely. Therefore, the other pin is redundant and can be used for other purposes.

[0003] Since the traditional lightning protection device can only transmit the tripping information after the lightning protection device is invalid, the traditional lightning protection device has a great safety hazard. The main reason is that more and more lightning protection devices use pressure sensitive resistance to suppress instantaneous high voltage, and the pressure sensitive resistance has a gradual deterioration process. The leakage current (the leakage current of new pressure sensitive resistance is about 10uA) gradually increases with the increase of the time of using the access circuit, slowly reduces the pressure sensitive voltage, and increases to about 10mA when the deterioration reaches a certain degree. The stability of pressure sensitive resistance will rise to more than 150 DEG C, so as to drive the disengagement device to act. There are two big risks in this process. First, before the tripping device starts, the pressure sensitive resistance has actually decreased in performance and cannot play a good protection role. Second, the tripping device often fails, causing the pressure sensitive resistance to fire and posing a great threat to the safety of people and property. CONTENT OF THE UTILITY MODEL
