Research on Discharging Detection Technology Based on UV Sensor

摘要

Under the coal mine, 10 kv high-voltage electrical equipment is prone to discharging. The discharging can lead to electrical equipment malfunction, reduction of service life, interference for radio communication network, to impact on safety production of coal mine. This paper analyzes the production mechanism of discharge phenomenon and spectral characteristics of ultraviolet radiation, adopts semiconductor UV sensor for ultraviolet signal collection and photoelectric conversion, uses MCU for data fitting processing, and designs a discharging detection system of high-voltage electrical equipment. The experimental results show that the system can detect the discharging degree of 10 kv high-voltage electrical equipment under the coal mine in the conditions of no electricity and non-contacting the charged body.
