<p>PURPOSE:To reduce an installed power source sharply and to simplify a temperature controller to be used for a fast breeder reactor by switching the power source and heater groups alternately to control temperature. CONSTITUTION:Plural electric heaters are divided into several heater groups 3-1 and 3-2 and an AC power source 1 and respective heaer groups 3-1 and 3-2 are connected through semiconductor switching elements 2-1 and 2-2. In addition, the AC power source 1 is also connected to a temperature controlling circuit 5 and a phase controlling circuit 4 to enter control signals 8-1 and 8-2 outputted from the temperaure controlling circuit 5 which has inputted signals from temperature sensors 7-1 and 7-2 for subjects 6-1 and 6-2 to be heated and phase controlling signals 9-1 and 9-2 from the pulse controlling circuit 4 in the semiconductor switching elements 2-1 and 2-2, switching over the hater groups 3-1 and 3-2 and controlling temperature through the temperature controlling circuit 5.</p> |
