Arc fault detection device based on POE technology

Abstract

The invention provides an arc fault detection device based on a POE technology. The device comprises a fault detection module, a data processing module, a POE power supply module, a CPU processor, an Ethernet communication module, a key module and a display module. The fault detection module is connected with the CPU processor through the data processing module, and the CPU processor is connected with the POE power supply module, the Ethernet communication module, the key module and the display module. The arc fault detection device has the advantages that firstly, the device can be obtained by improving a common Ethernet, needed cost is low, and the device is easy to build; secondly, compared with an arc fault detector scheme of a traditional 485 digital signal transmission mode, the device meets requirements of modern large-scale networking better; thirdly, the device can be suitable for different voltage levels and has good adaptability; fourthly, voltage in use is safe voltage, electric shock accidents of people can not occur, and on-site security is improved; fifthly, power consumption is low, and a lot of resources can be saved.

Description

Technical field [0001] The invention belongs to the technical field of low-voltage electrical appliances, and in particular relates to an arc fault detection device based on POE technology. Background technique [0002] With the development of existing technology, traditional miniature circuit breakers are becoming less and less able to meet the needs of various environments, especially the more and more complicated electrical equipment in modern buildings, leading to greater and greater danger of electrical fires. This led to the birth of the arc fault detector. [0003] The working power of the traditional arc fault detector is often taken from the line of the monitored point, but this kind of arc fault detector can often only detect several standard voltage levels and cannot meet the needs of the export market of different voltage levels. Summary of the invention [0004] In order to solve the above problems, the purpose of the present invention is to provide an arc fault detect...
