x-ray circuit

QuestionAnswer
Primary/Low voltage circuit * main switch * fuses *autotransformer * prereading kV meter * exposure circuit/switch
Main breaker/switch double blade, single throw
Fuses overload of circuit with excessive amps causes the metal strips within the fuse to melt breaking the circuit
Autotransformer changes voltage supplied to the primary of the transformer thereby providing various kv for x-ray tube
prereading kv meter indicates kv before the exposure is made
Timer and xray exposure switch control the current to the primary coil of the transformer ( duration of time)
Low Voltage/ Filament circuit Supplies the heating current for the filament of the x-ray tube **rheostat ** filament ammeter ** filament transformer
Rheostat Also called a variable resistor, the greater the resistance, the smaller the current
Filament Ammeter (lets you know the exposure is made) connected in a series, measures filament current
Filament transformer (low voltage side) step down transformer reduces current & voltage to the xray tube
Secondary/ High Voltage Circuit This is the portion where the voltage is stepped up by 500:0 or 1000:1 --step up transformer --rectifiers --mA meter --x-ray tube
step up transformer steps up the voltage
rectifiers changes AC supplied to the transformers to DC
mA meter connected in a series, measures the mA in the x-ray tube during exposure
x-ray tube where the x-rays are produced
