overview

Equipped with integrated remote control, telemetry and remote signaling automation modules, GJS-12 inflatable type realizes the intelligent application of ring network switchgear. The communication is used to connect each unit with the higher-level dispatching center, which can realize the comprehensive automation of the power distribution system. Distribution network automation enables dispatching and operation personnel to understand the operation of the entire distribution network without leaving home, quickly realize fault location, and automatically or manually realize fault isolation and network reconstruction, thereby greatly shortening the power outage area and time, and reducing the loss caused by failure. In addition, load monitoring and deployment can be easily carried out, which is conducive to the rational utilization of the network.

Matching the switchgear is the distribution network automation system. The system is open in design. It includes two parts: substation and automation terminal module. The modular design of the automation terminals offers high reliability and at the same time, their compact form factor facilitates installation in compact switchgear.
