This text with the low-pressure of the airport goes together with to give or get an electric shock the system as research object,going into detail the low-pressure electricity station in the emergence power factor lead low reason,definitely put forward understanding of method,and analyzed two kinds of in expiation of ways,after merge the capacitor repair power factor the problem that may appear.

Introduction was made to intellectualization technology of high and low voltage pre-assembled substation: with real-time high and low voltage electrical parameter measurement, calculation, analysis and memory technology; real-time monitoring fuse and load switch composition electrical apparatus operation state technology; real-time measurement for temperature in transformer chamber and t.

In this paper,the principle and composition of the boat is introduced,and the key technique that high pressure water mist,high pressure water cut,hydraulic electric station and multifunction integration are described.
