The intelligent demarcation switch is an important device in the intelligent distribution network. The access to the main station of the demarcation switch helps the company to monitor the customer's power usage, isolate the customer equipment faults in time, avoid large-scale power outages, and automatically report the fault information to the main The station system helps the equipment management unit to determine the cause of the fault and the point of failure, improve the correct rate of FA action, and improve the level of distribution automation and power supply reliability. Qingdao Power Supply Company started the demarcation switch to access the main station in June this year.

During the implementation of the project, the company formed a team that was the main force of the industry's experts and technical backbones, and coordinated the technical personnel of the relevant units to overcome the transformation problems. After pre-technical training, on-site testing, etc., confirming that the system equipment is working well and the technical conditions are mature, on August 20, the intelligent demarcation switch access to the main station is fully operational.

The task was tight and the task was heavy. The company dispatched 9 working groups and distributed them to the urban areas, Lushan and Huangdao. Due to the large number of demarcation switches, wide distribution range and harsh working environment, it is difficult for technicians to find equipment on site, especially cable-type demarcation switches, which are installed on the ground and are small in size, often blocked by green belts or in factories. The search is very difficult; the overhead type demarcation switch also needs to be put on the pole. The on-site technicians go up and down more than 20 times a day. When the work place is remote, in order to save time, lunch is solved at the work site.
