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.     
Langsongkeli has developed an uninterrupted remote transmission upgrade and renovation plan based on its load characteristics. The entire station adopts LoRa wireless remote transmission method to upload the insulation gas status of the equipment to the online monitoring platform, saving a lot of labor costs for operation and maintenance.
