2026-09-14
With the constant development of new energy systems and intelligent modernization of distribution networks, increasingly higher demands are placed on the switching equipment of 10 kV overhead distribution lines in terms of: reliability; degree of integration; level of intellectualization. Increasing the reliability of power supply and operating efficiency of distribution networks is one of the key tasks of modern modernization and automation of power systems.
Anhui Longpo Electric Co., Ltd., with nearly 30 years of experience in the electrical equipment industry, actively responds to market needs, focusing on high degree of integration, reliability, ease of operation and maintenance, and intelligent functions. With its deeply integrated integrated design, the company launched a new product, “ZW-12 Type Complete Pole Switch with Deep Integration of Primary and Secondary Systems.”
This product has a completely sealed and insulated structure, and is mainly used to realize the segmentation and interconnection functions of 10kV distribution network trunk lines. It adopts advanced technologies such as current sensors, voltage sensors, capacitor energy acquisition modules and line loss acquisition modules to realize adaptive, comprehensive on-site feeder control automation function. This feature allows it to adapt to distribution networks with multiple branches and connections, independent of the main station and communications, through short-circuit/ground detection and multi-level protection, providing selective line fault protection. In the event of a short circuit and single-phase grounding, the device can quickly locate the fault and automatically isolate it in place without affecting the power supply to undamaged areas, which greatly improves the reliability of power supply. In addition, this device has functions for calculating active and reactive power, power factor, frequency and amount of electricity, which allows you to monitor the state of the power grid in real time, promptly identify possible problems and, thus, more effectively manage and maintain the power grid.
