<p><P>PROBLEM TO BE SOLVED: To provide a transformer for magnetron drive which exhibits a high heat resistance and is small-sized as a whole by improving the heat resistance of heater windings and enabling to reduce their size. <P>SOLUTION: Since the heater windings 5 are formed of aluminum conductor which exhibits a higher heat resistance than copper, the heat resistance of the heater windings 5 can be improved. Also, since it exhibits a higher workability than copper, the lamination factor of the windings can be easily improved, and the size of the heater windings 5 can be reduced. In this way, the transformer 1 for magnetron drive can be obtained which exhibits a high heat resistance and is small-sized as a whole. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
