The invention relates to the technical field of electrified railway power supply contact networks, in particular to a contact network tension automatic compensation device, which is characterized in that a supporting column is included, wherein a temperature sensing compensator is connected with the supporting column through a tension adjusting rope, the temperature sensing compensator is connected with an insulator through a rope, and the other end of the insulator is connected with a carrier cable or a contact line. The temperature sensing compensator includes a housing, wherein a hole is formed in the bottom of the shell, sealing ring arranged in hole, and a heat-sensitive material is arranged in the shell; a piston is arranged on the heat-sensitive material; the heat-sensitive materialis sealed in the shell by the piston through a sealing gasket and a sealing ring; the piston is provided with a hole, a sealing ring is arranged in the hole, a pull ring is arranged at the bottom ofthe outer shell, the pull ring penetrates through the outer shell hole, the heat-sensitive material and the piston hole, the pull ring penetrates through the piston and then is provided with a gasket,a nut is arranged on the gasket, a pull ring is arranged on the outer shell, and the pull ring and the outer shell are fixed. According to the invention, when the environment temperature is changed,the tension of the contact line is kept unchanged all the time, and transportation, installation and maintenance are facilitated.
