Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] Such as figure 1 As shown, a kind of non-contact high-voltage line electroscope provided by the present invention includes: a capacitive sensor, which is used to monitor the electric field of the high-voltage line, and generates a voltage signal to send to the signal processing module; the signal processing module converts the received voltage signal into a digital The signal is sent to the single-chip microcomputer; the single-chip microcomputer processes the received digital signal, sends a power-on or power-off status indicator signal to the indicator module, sends a voice signal to the voice module, sends an alarm signal to the alarm module, and sends a transmission signal to the signal transmission module; The indicator module displays the state of electricity or no electricity through the light-emitting diode; the voice module sends out voice prompts accor...

Abstract

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.

Description

technical field [0001] The invention relates to the field of high-voltage line monitoring, in particular to a non-contact high-voltage line electroscope. Background technique [0002] Safety is the top priority in the production process, and it is especially important for ten dangerous operations. When the high-voltage line is powered off for maintenance, the regulations of power failure, power inspection, and hanging to the ground must be followed. The power inspection operation must be completed through an electroscope . The electroscope is one of the commonly used power safety tools used to detect whether there is voltage on the power equipment. Through the electroscope, it can be clearly verified whether there is no voltage in the power-off service equipment, and then other operations are performed to prevent the occurrence of electrified grounding wires (closing the grounding knife switch) ), mistakenly touching electrical equipment and other vicious accidents, therefo...
