3)Electrical Technique Instruction
Electrical parts of the equipment include rectification transformer, low-voltage switch cabinet, medium frequency power cabinet, filter reactor, and compensation capacitor bank and water tank.
3.1 Rectifying transformer
This equipment uses special-purpose rectification transformer, which transforms 35KV or 10KV high voltage of the electrical network to 950V, which is suitable for the solid state power.
There is a no- load manual changer at the high voltage side of transformer, output voltage can be adjusted at -5%, 0, +5%. It is used to suit the deviation of grid. In order to ensure the safety of silicon-controlled rectifier and avoid to impact on the grid, this transformer request the big short circuit resistance value 10%, simultaneously adds the shielding layer between the primary and secondary-coils. There are a gas relay and the oil thermometer on the power transformer, its output is interlock with high-voltage switch cabinet, when there appears the gas alarm or higher oil temperature, it will automatically turn off the power.
Cooling of the Transformer uses the oil-filled self-cooling.
3.2 Low-voltage switch cabinet
The low voltage switch-automatic air circuit breaker(DW15_1000V) is installed between the transformer output and the medium frequency power input, it is used in the make-and-break and isolates the overhaul of power source for maintenance.
The air circuit breaker has fast broken for overload protection and the no voltage release protection.
3.3 Medium frequency power source
Controllable medium frequency power supply is AC_DC_AC equipment. It uses silicon-controlled rectifier to change there-phase DC to single-phase AC. The equipment is strongly adoptive to any load, and is widely used in metal melting, heat treatment, and crystal's growth. The medium frequency source made by our company has some special feature list below:
