Description

 The role of microwave oven high-voltage diodes

1. There are two high-voltage diodes in the microwave oven. Their effects are rectifier high-voltage diodes; high-voltage maintenance effects; if the reverse voltage is too high, the diodes will reversely breakdown to form a path and maintain the circuit.

2. The effect of rectifying high-voltage diodes When the rectifying effect of the high-voltage diode is broken down, the high-voltage fuse will be blown, and the high-voltage diode will be blown internally. Only the high voltage is communicated, and there is no DC high voltage.

3. Add a certain DC voltage between the anode and the cathode. The electrons emitted from the cathode will fly to the anode under the influence of the positive potential of the anode. And the effect of electric field force to make wheel pendulum motion.

4. Because there is a high-frequency electric field in the anode resonant cavity, it will form an electron cloud that rotates around the anode; when the rotation speed is synchronized with the high-frequency magnetic field, the electrons transfer all energy to the high-frequency magnetic field, and then maintain high-frequency vibration.

Measurement methods

It is normal to measure with a digital multimeter. This diode is damped. It is broken if the heat is short-circuited.

General-purpose high-voltage diodes for microwave ovens, this tube is damaged, the

microwave oven does not heat, can replace HVM10, CL01-12, HVR-1×3, T3512, T4512, etc.

High voltage diodes for microwave ovens, withstand voltage of 12000 volts, 350mA.

It is best to make some tin at the two ends of the wiring before using the machine to prevent ignition.
