AI Technical Summary
Existing magnetically controlled FTU devices are installed on outdoor utility poles, making internal operation difficult. Furthermore, the high voltage and short time required for closing and opening operations make on-site commissioning and maintenance challenging.
A magnetically controlled FTU online commissioning system for closing and opening circuits was designed, including signal input/output circuits, signal processing circuits, closing/opening indicator circuits, closing/opening position indicator circuits, and charging circuits. It is powered by a lithium battery and connected to the FTU control port through an SP10W interface to realize simulated opening and closing function testing and remote signal reading.
It enables safe and reliable online commissioning and maintenance, eliminates the danger of high voltage, can quickly determine the functional status of FTU, has a long battery life, and is convenient for outdoor workers to use.
