Safety monitoring and protection of switchgear

Through a series of sensor test researches on a variety of light sources, the characteristics of the internal arc arc arc are determined. On this basis, the optical fiber sensor and an economical and practical distributed multi-point internal arc arc are developed using the arc single criterion rule. Detection and protection device. The device is not only simple in structure, low in cost, but also has fast action time and strong anti-interference ability; it can not only be used alone, but also can be integrated with various relay protection devices, so that the switchgear is not much more expensive The technical level and added value have been greatly improved.
