Application of Ankerui Power Management System in Baicheng Mobile-Yang Junjun
Introduce the Ankerui Power Management System, which uses intelligent power meters to collect various electrical parameters in the substation. The system adopts the on-site local networking mode. After the network is connected, it is transmitted to the monitoring background through fieldbus communication. Through the power management system, real-time monitoring and management of the power distribution circuit of the substation is realized.
Diesel nozzle tester is a basic tool for a diesel injection service lab.
Manual nozzle tester is also know as pop tester, used to test mechanical injector, or test common rail electronic injector by cooperate with a simulator.
Diesel injector nozzle tester is used to calibrate the injection nozzle opening pressure, check leakage, check fuel spray pattern etc.

0 Overview
Baicheng Mobile Communications Branch was established in July 1999 and is affiliated to China Mobile Communications Group Jilin Co., Ltd. The company has 251 formal employees, 381 social workers, 550 million yuan in fixed assets, 281 base stations, nearly one million online users, more than 300 million business revenues, and a market share of 71.44%.
A total of 34 0.4KV circuits in the power distribution cabinets in the substation of this project need to be monitored.
1 Customer needs
According to its actual situation, the following requirements are proposed:
1.1 The main purpose of this design and integration is to centrally manage the distribution circuit and realize data sharing.
1.2 When the current of each loop exceeds the limit, it cannot be known by the management personnel in real time. There is a hidden danger in the safe use of electricity, and the system needs to realize the sound and light alarm function.
1.3 Real-time monitoring of real-time current, voltage, and power fluctuations of each loop.
1.4 can view the daily electricity consumption of a specific loop or several loops, and can be compared through the report.
According to the needs of users, it is necessary to network the power distribution cabinets in the substation and establish a power management system (mainly real-time monitoring of data), set up a monitoring platform in the control center duty room, and monitor, count and analyze 34 0.4KV loops in real time. To ensure safe, reliable and efficient use of electricity.
Ankerui Power Management System makes full use of the latest developments in modern electronic technology, computer technology, network technology and fieldbus technology, and performs distributed data collection and centralized monitoring and management of variable power distribution systems. The secondary equipment of the power distribution system is networked, and the field devices of the distributed power distribution stations are connected as an organic whole through the computer and the communication network to realize remote monitoring and centralized management of the power grid operation.
