Overview
Microwave energy produces by microwave generator, microwave generator includes microwave canal and microwave canal power supply two parts. Among them microwave provides power source (abbreviation power source or microwave source) action is can turn commonly used alternating current into dc electric energy, the job that provides for microwave creates a condition. Microwave is in charge of the core that is microwave generator, it becomes change of dc electric energy microwave can.
Microwave canal has microwave transistor and microwave valve two kinds big. Power of microwave transistor output is lesser, use at measuring to wait for a domain with communication commonly. Microwave valve is a lot of more phyletic, commonly usedly magnetism accuses canal of canal, klystron, travelling wave to wait. Their working principle different, structure different, function each different, defy in radar, navigation, communication, electron and heat, the respect such as scientific research receives wide application. Because magnetism controls tubal construction,depress of report of tall, job, power source mixes simple, efficiency simply the capability that gets used to laden change is strong, consequently special apply to microwave to heat with microwave can other application. Because work,magnetism accuses a canal of condition different can divide accuse canal and successive wave magnetism to accuse to be in charge of two kinds for pulse magnetism. Microwave heating installation basically works at successive wave condition, so magnetism of multi-purpose and successive wave accuses a canal.
Magnetism accuses a canal is one kind uses generation microwave can electrovacuum parts of an apparatus. It is a park essentially constant the diode in magnetic field. The electron inside the canal is in mutual and perpendicular constant magnetic field and constant below the control of electric field, produce interaction with field of high frequency electromagnetism, from constant energy change is obtained to become microwave energy in electric field, achieve generation microwave thereby can purpose.
Magnetism accuses to provide sort a lot of, much antrum basically introduces here successive wave magnetism accuses a canal.
Magnetism accuses a canal to be mixed by tubal core magnet steel (or electro-magnet) composition. The construction that manages core includes zincous, cathode, energy out-put implement wait for 4 parts with magnetic circuit system. Pipe interior holds high vacuum position. The structure that departmental cent introduces respectively below reachs its action.
1 positive pole
Positive pole is one of main composition that magnetism accuses to be in charge of, it and cathode make the vacuum of electron and interaction of magnetic field of high frequency report together. Be in constant magnetic field and constant below the action of electric field, the electron finishs the job that energy changes inside this space. The positive pole that magnetism accuses to be in charge of is divided outside collecting an electron like the positive pole of common diode, the oscillation frequency that returns magnetic field of pair of high frequency report is having conclusive effect.
