content: I have safely removed an microwave transformer form the microwave for no reason. But would it be safe to use the microwave transformer as an paper weight/ornament on my desk just for decoration. ?

content: Well since this is a ridiculous question: the only problem i can think of potentially is fiberglass insulation in between the transformer winding and the magnetic circuit can possibly fray and leak bits of fiber glass particles, if you think of some mechanism to stress the material if its present. And they are kinda make cheap so you can get a fine diamond file or sand paper and debur the edges if you notice any sharp ones.I assume you are a teacher at a school or something.Putting it on a wooden or plastic plate might protect a nice desk too because its liable to scratch it.The main hazard is dropping it on your foot and breaking a toe. Some commercial offices might have a manager that gives you problems over this. No known cure for this. Harassment authority gets its game on and you end up fighting with hr over a paperweight. Retarded as fuck.

content: I think the risk you take by doing such thing is just as bad as having a spare tire on your desk.... You have to really work at it to get hurt.

content: If you cut off the primary input wires right where they enter the transformer no one is ever going to get high voltage out of it again.

content: this is actually "High Voltage transformer", this is not "Microwave transformer".Microwave is a wrong name for it.Because "microwave transformer" means that transformer is designed to work with microwave frequency, but this is not the case for transformer used in microwave oven. It works with low frequency 50/60 Hz and so, cannot be named "microwave".The transformer is safe. The main danger is High Voltage capacitor, because it can hold and accumulate high energy. So, you're need to make sure that it's contacts are shortened when you store it. But the High Voltage transformer is safe, if you will not connect it to AC power supply of courseThere is also possible danger if you try to disassemble these transformers or capacitors which contains oil. Because it may contains some chemicals, which may be very poison!For examle this 200 V, 6 uF soviet capacitor of type "КБГ-МН" contains "Sovol".this is biological hazard and poison substance. And this is dangerous to contact with it. It is also used in some kind of transformers.So, don't try to disassemble these things. And keep away from damaged one.This is dangerous for your health and for biological nature.Especially be careful if you deal with oil transformer or capacitor, which doesn't have possibility of draining or changing the oil. They especially designed in such way to avoid contact with poison substance. These substances known as "Sovol", "Sovtol", "ПХБ" (also known as "PCB" in english or polychlorinated biphenyl).For example, be very careful if you see sticker something like that:There is a high risk that High Voltage capacitor used in microwave oven contains polychlorinated biphenyl. So, never disassemble it. It may contains toxic chemical substance.
