Example Embodiment
[0021] The present invention will be described in detail below with reference to the drawings and embodiments.
[0022] Please refer to figure 1 , figure 1 It shows the composition block diagram of the arc monitoring and protection system based on pressure protection provided by the embodiment of the present invention.
[0023] The system is set in a closed power distribution cabinet; the device includes: an arc sensor, a pressure sensor, a fast grounding switch and a central processing module.
[0024] The arc sensor is a fiber optic cable, and the arc sensor is laid in a serpentine shape in the power distribution cabinet; in the embodiment of the present invention, POF (Polymer Optical Fiber) is generally selected for the fiber optic cable to meet the arc monitoring needs. If the cost is not considered, SOF (Quartz Optical fiber) can achieve a light transmittance of more than 99% and an attenuation rate of less than 20Db\km.
[0025] The pressure sensor is a single crystal silicon...
