Detection method of microwave oven magnetron:<\/strong><\/div>\n
\u00a0<\/div>\n
<\/div>\n
The magnetron is a key component of the microwave oven. It is mainly composed of a tube core and a magnet. The tube core is<\/div>\n
composed of a cathode, a filament, an anode, and an antenna (waveguide). Its working principle is: after the power is turned<\/div>\n
on, the 3.3V alternating current generated at both ends of the secondary filament coil of the high-voltage transformer<\/div>\n
supplies power to the magnetron filament. At the same time, the about 2000V AC high voltage generated by the high voltage<\/div>\n
winding is limited by the high voltage capacitor. After the diode rectifies, about 2000V DC high voltage is added to the<\/div>\n
anode of the magnetron to form an accelerating electric field (the anode is grounded, and the cathode is actually negative<\/div>\n
2000V). The electrons emitted from the cathode (direct heating and indirect heating, in Figure 2) are accelerated to the<\/div>\n
anode. In the process of accelerating the electron to the anode, it is also affected by the strong magnetic field in the<\/div>\n
vertical direction formed by the permanent magnet. Therefore, the electron is rotating and accelerating toward the anode<\/div>\n
(just like the movement of a bullet in a barrel). It also keeps getting faster. The anode is made into an internal gear<\/div>\n
shape, forming an even number of cavities, called resonant cavities. Each resonant cavity is a microwave resonator, and its<\/div>\n
resonant frequency depends on the size of the resonant cavity. The electrons oscillate when they pass through the fan-shaped<\/div>\n
cavity. And the frequency keeps increasing. When the frequency reaches 2400MHz, microwaves are formed, emitted from the<\/div>\n
waveguide port, and then transmitted to the furnace to heat the food.<\/div>\n
The quality of the magnetron is mainly to measure the filament (for the direct heating type is the cathode, most of which<\/div>\n
are currently the direct heating type). Including whether the inductance coil with the magnetic rod as the iron core is<\/div>\n
open, that is, the lead ends of the filament on the magnetron should be connected (but the resistance of the shell should be<\/div>\n
infinite), and the normal resistance should be less than 1\u03a9. This is also a sign of judging whether it is aging. The smaller<\/div>\n
the value, the better. If it is greater than 1\u03a9, it means aging. It is best to pay attention to the power and mounting pin<\/div>\n
position consistent with the original tube when replacing. If the power is too small, the original heating effect cannot be<\/div>\n
achieved (although the magnetron power has some room for adjustment); if the power is too large, it may damage the<\/div>\n
high-voltage converter or high-voltage rectifier diode. In addition, for the characteristics of the high-pressure fuse.<\/div>\n
Mainly it has a longer shape (4cm) and has a time-delay feature. It is installed in a special insulated fuse box and cannot<\/div>\n
be replaced by an ordinary fuse. Some people use the 3.15A time-delay fuse used in color TVs instead. Not only the fusing<\/div>\n
current is too large, it does not provide insurance, and its short length does not meet the high-voltage requirements.<\/div>\n
Filament cold resistance: use a multimeter, the same below. R\u00d71k block test, normally less than 1 Q (usually tens of m\u03a9, the<\/div>\n
resistance between the filament and the tube case is measured with R\u00d710k block, and it is normally infinite.<\/div>\n
\u00a0<\/div>\n
<\/div>\n
<\/div>\n
Large filament resistance is one of the common reasons for the low output power of the magnetron If the measured filament <\/strong><\/div>\n
resistance is large, do not easily judge that the magnetron is broken or aging. Practice shows that most of this situation <\/strong><\/div>\n
is the contact resistance formed after the magnetron filament pin or socket is oxidized and fouled.<\/strong><\/div>\n
\u00a0<\/div>\n
It is also the measurement error. It is usually caused by the contact resistance between the test lead of the multimeter and the measuring<\/div>\n
point, or the test lead and the socket. The problems of the magnetron itself are rare. Generally, only the service life has<\/div>\n
expired, long-term overload work or a few magnetic products with quality defects. This kind of failure can happen to the<\/div>\n
control tube. Therefore, when testing, the multimeter should be normal and the measurement method should be correct. Second,<\/div>\n
the magnetron pin should be sanded or scraped, and the dirt and oxide should be removed before measuring. If measuring the<\/div>\n
resistance If it is still large, it can be judged that the magnetron is bad.<\/div>\n
The open circuit of the filament is mostly caused by the damage of the magnetron itself. Generally speaking, it has to be<\/div>\n
replaced with a new tube. However, a few open circuit of the magnetron filament is caused by the lead wire unsoldering. When<\/div>\n
repairing, you can pry off the filament base, then use wire pliers to clamp the lead and the connecting piece, and then use<\/div>\n
a soldering iron to solder firmly.<\/div>\n
