Non-contact high-voltage line electroscope
2013
The invention discloses a non-contact high-voltage line electroscope, comprising a capacitance-type sensor, a signal processing module, a singlechip, an indication module, a voice module, a signal transmission module and an alarm. The capacitance-type sensor is used for monitoring a high-voltage line electric field, generating a voltage signal and transmitting the voltage signal to the signal processing module; the signal processing module converts the received voltage signal into a digital signal and transmits the digital signal to the singlechip; the singlechip processes the received digital signal, transmits a charged or uncharged state indication signal to the indication module, transmits a voice signal to the voice module, transmits an alarm signal to an alarm module and transmits a transmission signal to the signal transmission module; the indication module displays the charged or uncharged state through a light-emitting diode; the voice module gives voice prompt according to the voice signal; the signal transmission module transmits the received transmission signal to a console; the alarm gives an alarm after receiving the alarm signal. The non-contact high-voltage line electroscope uses the singlechip as a detection and control core, provides both vision and voice prompts when giving electricity checking caution, and has steady system signal and high reliability.
