MICROWAVE OVEN POWER SUPPLY UNIT AND HIGH- VOLTAGE FUSE FOR SAID POWER SUPPLY UNIT Russian patent published in 2000 - IPC

FIELD: microwave ovens. SUBSTANCE: device has high-voltage transformer, which converts alternating current voltage, which is received by first winding, into high voltage which is output by second winding. High-voltage fuse is connected to ground and terminal of second winding of high-voltage transformer, which is connected to ground. High-voltage diode absorbs pulse voltage, which is applied to ground and is connected in parallel to high- voltage capacitor. Magnetron is connected to output of high-voltage capacitor and produces electromagnetic microwave radiation. High- voltage fuse has insulator. First holder is located in insulator. Second holder has ring terminal for connection to ground on end which is opposite to first holder. Fuse housing is located between first and second holders. Wire terminal of fuse is connected to first holder. Clip is attached to another end of wire terminal by means of its pressing to welding. EFFECT: increased reliability of protection. 3 cl, 2 dwg
