THT-XDL microcomputer small current grounding line selection device
The THT-XDL microcomputer small current system grounding selection device adopts new technology and advanced principles to develop a new intelligent selection device. It can quickly and accurately locate single-phase grounding lines in small current systems, with a focus on solving the problem of long-term reliable operation of the device in harsh environments. Its structure is more reasonable and lightweight, which can be used for the renovation of old power plants and substations, as well as for new power plants and substations, directly forming a comprehensive automation system.
This device is widely used in power supply systems for substations, power plants, hydropower stations, and large factories and mining enterprises such as petroleum, chemical, metallurgical, coal, railways, and construction.
Using Atmel's RISC single-chip microcontroller as the operation acquisition, logic judgment, and control center, and LCD display, signal indicator lights, touch buttons, and micro printers as the human-machine interface, it has the characteristics of simple operation, accurate line selection, and reliable operation. At the same time, it can memorize instantaneous grounding information, distinguish between busbar and outgoing line grounding, and can be equipped with communication interfaces, providing a basis for on-site analysis of relevant parts.
