TV ignition coil
CRT electron gun capable of emitting a tail of hot electrons and accelerated by an electric field bombarding the screen, and smear on the screen of a fluorescent substance emits light. The faster the speed of the electron beam, the brightness becomes. To increase the speed of the electron, it is necessary to enhance the acceleration voltage of an electric field to the electron beam acceleration energy higher. AC output is rectified high voltage package, you can create the positive front of high voltage electric field, electrons are accelerated in the electric field, the image will have a sufficient brightness.
Line output transformer ignition coil is commonly known, high voltage DC output, is the role of the ignition coil. The role of television sets, is exactly the same. Used to accelerate electrons in a TV screen to achieve adequate brightness, also used in liquid crystal display computer, used to power the lamp so that the screen to achieve adequate brightness.
Of course each TV, the display in the ignition coil models are not the same, the maintenance personnel to recognize the changing TV ignition coil model. So as to avoid a series of unnecessary risks.
Early use of black and white TV discrete output transformer (commonly known as the ignition coil). Fault This output transformer is packaged silicon pillar high pressure cylinder ignition, arc, resulting in deterioration of the inner wall of the breakdown, but most are not necessarily damage the coils.
Motorcycle ignition coil
Also known motorcycle ignition coil ignition coil, the primary coil, the secondary coil and core components. When using give primary coil charging in a coil induces a voltage from 200 ~ 300 V; then, the mutual inductance and the secondary coil to produce a 18 ~ 20 kV high voltage, the voltage generated depends on the two coil turns number ratio; and finally delivered to the high-voltage spark plug ignition. [1]
Motorcycle ignition coil is a step-up transformer, the voltage of 6V or 12V motorcycle generators to generate increased to 12000V, to the spark plug ignition. Today, the ignition coil are closed, broken only new ones, and check the ignition coil is good or bad, as long as the spark plug Remove the spark plug put links, turn the ignition key, spark plug against the outer end of the engine, with the foot Start moving motorcycle rod, observe the spark plug ignition, the play of blue sparks, crackling sound clear and strong, indicating good ignition coil, ignition coil has burned no spark explanation, dark red sparks shot shows the inside of the ignition coil coil short circuit, it should be scrapped.
Working principle is by applying a DC to AC oscillator, boosted by the booster circuit and then rectified into DC high voltage, when the voltage to rise to a certain value to the igniter sparking power.
