Problems solved by technology

[0005] Some existing mature communities or old unit communities use simple fool-style SPDs. This kind of SPD usually uses diodes to display the working status. The green light is on when it is working normally, and the red light is on when it is abnormal. The staff can only know the SPD through on-site investigation. Therefore, some SPDs with alarm or upload function appeared. The new SPD itself has a detection circuit inside, which can judge the work of SPD according to the arc, temperature and fuse state. status, but the application of the new SPD in the existing mature communities requires a large amount of engineering. It is necessary to remove the old fool-style SPD and reinstall the new SPD. The cost of this method is very high, but for the SPD The demand for monitoring is increasing day by day, and people are looking for how to add a stable and reliable monitoring device without changing the original SPD through simple installation and other methods

Abstract

The invention discloses an SPD temperature alarm device. The device comprises a temperature acquisition module, a control analysis module, a communication transmission module and a shell, wherein thetemperature acquisition module, the control analysis module and the communication transmission module are all installed in the shell; the output of the temperature acquisition module is connected withthe input of the control analysis module; and the output of the control analysis module is connected with the input of the communication transmission module. The SPD identification alarm device is directly added on an existing SPD to realize identification alarm of the traditional fool-style SPD and has the high practicability and the important social significance.

Description

technical field [0001] The invention relates to the field of lightning protection devices, in particular to an SPD temperature alarm device. Background technique [0002] Lightning disasters are one of the most serious natural disasters, causing countless casualties and property losses worldwide every year. With the extensive application of electronic and microelectronic integrated equipment, the damage to systems and equipment caused by lightning overvoltage and lightning electromagnetic pulse is increasing. Therefore, it is very important to solve the lightning disaster protection problems of buildings and electronic information systems as soon as possible. [0003] With the increasingly stringent requirements for lightning protection of related equipment, it has become one of the important links of modern lightning protection technology to install surge protectors (Surge Protection Device, SPD) to suppress the surge and instantaneous overvoltage on the line, and to disch...
