Carry the fusing when failure and protect electrical equipment to cut off circuit, thermistor can change the big of resistance value according to temperature level
Small, when circuit overheats, thermistor can increase resistance value to reduce electric current, protect the electrical equipment in circuit, first resistor and the
Two resistance play the role of partial pressure, and excitation is exactly the meaning that excitation produces in magnet exciting coil, by the electric current of change in coil,
Just there is the magnetic line of force along hub of a spool by the way that current changing rate is bigger, and the magnetic line of force is also more, until saturation, turn-off current, the magnetic line of force
Disappear, the first capacitance and the second capacitance are acted on separated by direct communication, and three-phase electricity warp only can be left alternating current, the one or two pole later
Pipe, the second diode, the 3rd diode, the 4th diode have the function that rectification, will be upper by the unilateral conduction of diode
The alternating current of lower floating is converted to unidirectional direct current, and the 4th resistance, the 5th resistance, the 6th resistance, the 7th resistance can will be whole
Unidirectional direct current after stream is filtered processing, by the waveform stabilization of unidirectional direct current in the range of a very little, the
Eight resistance, the 9th resistance, the tenth resistance, the 11st resistance, the 3rd capacitance constitute an oscillating circuit, can produce sine
Ripple, reduces the frequency of vibration by increasing the resistance value of resistance, stablizes the waveform of sine wave, when logical in the primary coil of transformer
When having alternating current, exchange flux is just produced in iron core, makes to induce voltage in secondary coil(Or electric current).Transformer is by iron core
Formed with coil, coil has two or more windings, wherein connect the winding of power supply primary coil, remaining winding
Secondary coil, in generator, either coil movement by magnetic field or Movement in Magnetic Field by fixed coil, can be in coil
Induced potential, this two kinds of situations, the value of magnetic flux is constant, but has variation with the magnetic flux quantity of coil intersecting chain, this is mutual inductance
The principle answered, transformer are exactly inductance, the 4th electrolytic capacitor, the come voltage of transformation, electric current and impedance using undesirable mutual electromagnetic inductance effect
Five electrolytic capacitors, the 6th electrolytic capacitor, the 7th electrolytic capacitor form LC oscillating circuits, can produce high_frequency sine wave signal, LC
Oscillating circuit has used capacitance with the energy storage characteristic of inductance, allows two kinds of energy of electromagnetism alternately to convert, that is to say, that electric energy is with magnetic energy
As soon as there will be a maximin, also there is vibration, but this is ideal situation, actually all electronic components can all have
Loss, otherwise energy in capacitance with being depleted between inductance during mutual inversion of phases, or leak out outside, energy can constantly
Reduce, so actual LC oscillating circuits are required for an amplifier element, are exactly triode, using this triode, pass through
Various signal feedback methods cause the oscillator signal that this is constantly consumed by feedback amplify so that one amplitude of final output with
The more stable signal of frequency, triode is Current amplifier device, and in addition to it can coordinate LC oscillating circuits, it can also be
Faint electric signal becomes the signal of some strength.
Cathode one end of zener diode ZD1 tube bodies is planar shaped, and anode one end is semi circular surface shape, for overvoltage protection.
Triode Q1 is NPN type triode, and collector current is to flow to emitter from collector, and base current is from base stage
Flow into.
