Online monitoring renovation cases

Tai'an Zhongtianmen Substation is located in Mount Taishan Scenic Area. Its 10kV high-voltage room is equipped with Tianjin Pinggao gas insulated metal enclosed switchgear. The pressure status of the original equipment depends on regular manual inspection, and the dial pointer of the density meter can only be observed by opening the cabinet door.     

The Shandong Quancheng 1000kV substation is a hub substation of Shandong Province's super grid and the receiving substation of the Ximeng Shandong ultra-high voltage AC project. The original 110kV area of the substation was equipped with ordinary density relays for switchgear such as Xidian and ABB. Langsongkeli upgraded the equipment pressure status through digitization and uploaded it to the four party comprehensive automation monitoring platform in the station through the IEC61850 protocol, providing real-time, intuitive, and effective equipment condition judgment for operators.

Lianyungang 220kV Liangqiu Station is a green and smart substation of Subei Power Grid, located in Ganyu District, Lianyungang City. Langsongkeli has developed an online monitoring plan for SF6 gas status of Taikai and Pinggao GIS equipment based on the customer's smart station needs.
