The correct name of high voltage 你從coil is circuit output transformer, al上用so known as circuit coil or circuit t車個ransformer. The working pr生木inciple of the display and藍紅 TV high voltage coil is ba員鐘sically the same. Due to the 歌做high temperature, high freq老科uency, high voltage and h下綠igh current status of high-volta是術ge coil, as well as 喝月the impact of external environmental外明 humidity or dust, the pro男音bability of high-voltage coil da鐘電mage is very high. Now 高劇let's take a look at the classification玩離 of high voltage coi外生ls.

1. TV high voltage coi快很l

The electron gun at the rear of the 她近picture tube emits ther理文mionic electrons. As the electr朋為ic field accelerates and bombard去腦s the screen, the phosphor現知 coated on the screen will glow.大房 The faster the electron beam moves一笑, the brighter it will be. In order吧他 to improve the electron speed, it is n兵老ecessary to increase 筆志the voltage of the accelerating腦用 electric field, so that the electron就子 beam can obtain higher accelerating草在 energy. After rectification, the A外很C output in the high voltage b做理ag first generates a high voltage e問兒lectric field with the p關雨ositive pole. The electron 都老accelerates in this ele在司ctric field, and the image線來 has enough brightness.

The high-voltage coil is comm內現only known as the cir城師cuit output transformer, and冷資 the output of high-voltage DC is t場好he function of the high-voltage coil. T店你his function is exactly t吧河he same as the high-vol花光tage coil in the TV. When used in TV相車, it is used to acceler就們ate the electronic screen to achie林話ve sufficient brightness. When好內 used for computer LCD好問 screen, it can supply pow船就er to the lamp to make the s放我creen reach enough brig作要htness. Of course, each TV and m店很onitor has different types of high放數-voltage coil. The maintenance p志得ersonnel should pay attention to the 家外model when replacing the 弟她TV high voltage coil. In this way, a紅資 series of unnecessary dan問小gers can be avoided.

2. Motorcycle high-pressure coil

Motorcycle high-volta線車ge coil, also known a有海s ignition coil, is composed of prima們金ry coil, secondary coil高了 and iron core. When using, first c哥吧harge the primary coil, and induce什但 200-300V voltage in the primary c樂線oil; Then a high volt白紙age of 18-20kV is gen水理erated by mutual indu下低ctance with the secondary coil, and唱術 the generated voltage depends on the t可民urn ratio of the two coils; Then send通那 the high-voltage power t爸身o the spark plug for站腦 ignition.

The working principle of the 這河high voltage coil is to c唱視onvert DC to AC through the o機街scillator, boost the西到 voltage through the boost circuit, and公謝 then rectify it to DC high voltage討購. When the voltage rises to 都我a certain value, energize the ignit信呢er to ignite it.
