Counter adopts zinc oxide resistance sheet, and described zinc oxide resistance sheet is the resistor disc of high tolerance, low gradient, and through-current capability is strong, and residual voltage is low.
Described detection data comprise time and number of times.
Described remote monitoring center arranges counter automatic clear module.
Described counter automatic clear module manually can arrange the clearing time or reset number of times.
Described signal transmission unit adopts Optical Fiber Transmission.
Owing to adopting technique scheme, the present invention has following superiority:
1, the present invention can realize long-rangely monitoring lightning arrester discharge, staff is not needed to read the thunderbolt number of pick-up unit display one by one, audio-switch can thunder arrive when opening detecting device, ensure the continuation of the journey of device, save the energy, Optical Fiber Transmission is adopted to ensure the fast transport of signal, and also ensured the stability of Signal transmissions at thunderstorm weather, counter is highly sensitive, misoperation is little, record accurately and reliably, show clear obviously, light structure, good looking appearance, easy to install, sealing is reliable, long service life
2, the present invention is owing to have employed high tolerance, low gradient zinc oxide resistance card, and the discharge capacity of counter of the present invention is large, thus can ensure the discharge capacity being not less than lightning arrester.
3, detection data can be sent to remote monitoring center and be stored detection data by storer by monitoring system of the present invention, the action comprehensively long-term monitoring being kept away to device serves certain reference role, and recording time and the number of times of lightning arrester, record is accurate, recording interval is wide.
4, counter of the present invention arranges the consistance that automatic clear module ensure that the detection action of action on counter and Surveillance center.
