System overview

The system is a distributed monitoring, centralized management and instant notification mode with long-distance transmission capability. The background fault location software cooperates with the on-site fault detection and indication device. Within a few minutes after the fault occurs, the fault location and time can be displayed on the background interface. At the same time, the fault location results can be forwarded to the designated person's mobile phone number to help the maintenance personnel rush to the site quickly to remove the fault and restore the normal power supply.

Scope of application

■Automation construction mode of distribution network in small and medium-sized cities and counties；

■Reconstruction of automatic cable line of urban distribution network；

■Application area: Class C / D / E power supply area。

system function

Realize fast fault finding and locating, reduce fault inspection and fault handling time。

System characteristics

■ Fast fault location: accurate fault location within 2-5 minutes

■ Accurate fault location: the accuracy of short-circuit fault can reach 99%, and the accuracy of ground fault can reach 90%；

■ High cost performance of investment: more than 90% less than the traditional automation construction scheme, and the same investment amount covers a wider range；

■ The project construction is convenient: no need to transform the primary equipment, special tools are used for installation and disassembly, no need to cut off power for the transformation of American ring network cabinet and other equipment, and only a short cut of power for the transformation of European ring network cabinet；

■ Flexible operation mode: it can be used as an independent platform for rapid repair of distribution network faults, or as a "remote" module in distribution network automation system, with good scalability and compatibility；

■ Simple communication mode: optical fiber communication mode is adopted from short-circuit ground fault indicator to panel indicator; wireless communication mode is adopted from panel indicator to data forwarding station, and GPRS / SMS communication mode is adopted for data forwarding station。
