Power supply diagram of the shaft resistance furnace

A schematic single-line diagram of the power supply of a 5,5x6,5 m resistance shaft furnace is presented. The kit also includes a schematic diagram of the furnace control. The entire oven space is divided into 3 heating zones. Each zone is independently controlled by the TPM power regulator. The commands for regulation are given by PID-regulators included in the set of TPM power regulators.
