Abstract

In order to analyze the difference between temperature rise and the current carrying capacity of cable lines in pipe and tunnel, this paper first analyzes the temperature rise under the laying condition of tunnel and pipe and the calculation method of load flow, and applied the same test current on a 220kV cable test circuit in pipe and in tunnel under laboratory conditions, by measuring the cable conductor temperature rise with thermocouple measurement technology. The applied current is the 24h steady state current and the 24h transient current, and the difference of the temperature rise of the cable is compared under the conditions of the tunnel and the pipe under the two current conditions. The temperature rise of the cable is compared with the two different ways of laying, and the influence of the steady state current and the time varying current on the temperature rise of the cable conductor is also compared.
