Abstract

The thermal environment of the pipe gallery employing the gas-insulated metal-enclosed transmission lines (GIL) has a direct influence on the safe operation and service life of the line, so effectively eliminate the heat dissipation of the line can ensure the reasonable temperature distribution of the pipe gallery. The paper takes a underground GIL pipe gallery of Qingdao City as the research object and then the corresponding simulation analysis is conducted. The FLUENT software is employed to establish the physical model of GIL pipe gallery, and the ventilation mode adopting both mechanical air intake and mechanical exhaust air is set. Accordingly, the rules of indoor temperature distribution can be investigated for both normal and abnormal working conditions in winter or summer, The simulation results show that the inlet air temperature has a great influence on the temperature distribution of pipe gallery, the indoor overall temperature of the pipe gallery increases with the air supply temperature; in addition, the surrounding local temperature of GIL is too high under abnormal conditions in summer, and cannot meet the specification requirements because the temperature cannot be higher than 40°. Therefore, the timely maintenance should be conducted to avoid the occurrence of such conditions as far as possible. The research results of the paper can provide theoretical basis and technical guidance for the application of ventilation of GIL pipe gallery.
