Which transformer is used in microwave oven?
The high voltage transformer is essentially employed into home appliances such as a microwave oven which generates microwave to cook the foods, or the like, in order to supply the high voltage thereto. FIG. 1 is a perspective view showing a conventional high voltage transformer.
How many amps is a microwave transformer?
However, the primary current would be more like 20 amps (2300 watts / 120 volts) in normal operation so you may find the fuses in your variac blowing if you try to use that sort of power from the transformer.
What causes a microwave transformer to fail?
Most popular reason behind this issue is magnetron failure. … A burned magnetron has to be replaced as it cannot be repaired. Other probable causes behind this problem are faulty diodes, capacitor burn, defective door switch and transformer failure.
What are microwave transformers made of?
The microwave oven transformer has three windings, one of which is a primary winding, and AC 220V mains voltage is applied to this winding; a plurality of silicon steel sheets of a certain thickness are inserted between the primary and secondary windings, so that a high magnetic resistance is formed in the transformer.
How much voltage does a magnetron need?
For a microwave oven to operate, approximately Ϫ 4 kV should be applied to the magnetron cathode. The voltage is conventionally obtained by a high-voltage transformer and it is rectified by a half-wave rectification circuit.
How many volts are in a transformer?
Electric power leaves the distribution substation with voltage ranging typically between 4,000 and 36,000 volts.
How many amps does a typical microwave draw?
The microwave ovens consume power at a rate of 650– 1200 watt, which equates to a current of around 10 Amps.
Can I run a microwave on a 15 amp circuit?
A microwave plugged into a 15-amp circuit could cause the wires in the wall to overheat and present a fire hazard. More likely, however, the microwave will trip the 15-amp breaker and pose a regular nuissance. Note that you should never just replace a 15-amp breaker with a 20-amp breaker.
