The principle of high voltage package 200, the principle and structure of high voltage package of co

The working principle of the high-voltage package and the TV is basically the same, and its main function is to generate high voltage at the anode, and provide various voltages such as focusing, acceleration, and gate. Due to the high voltage package working in the state of high temperature, high frequency, high voltage and high current, coupled with the influence of factors such as humidity or dust in the external environment, the probability of damage to the high voltage package is high.

The high-voltage package is commonly known as the line output transformer, which outputs high-voltage direct current.

It's the role of the high-pressure pack. This is exactly the same as the high-voltage pack in a TV. When used in televisions, it is used to accelerate electronic screens to achieve sufficient brightness, and when used in computer LCD screens.

, you can supply power to the lamp to make the screen reach enough brightness.

The number of turns of the primary coil of the AC transformer is directly proportional to the transformer ratio of the number of secondary turns. Use 555 to form an oscillation circuit, and then use the power tube to drive to the high-voltage pack.

The ignition coil is mainly composed of a primary coil, a secondary coil and an iron core, which is actually a transformer. The iron core is made of dozens of steel sheets or steel wires superimposed, and the secondary coil is made of copper wire with the thickness of a hair around the iron core for more than 10,000 turns, one end of which is connected to a capacitor (high-voltage terminal), and the other end is connected to a primary coil; The primary coil is a thick layer of insulating paper wrapped around the secondary coil, and then hundreds of turns of copper wire are wound on it. Its working principle is to supply power to the primary coil by the igniter, and the voltage of 200 300 volts is induced in the primary coil, and it is mutually induced with the secondary coil to produce 10000 20000V high-voltage electricity, and the voltage generated depends on the ratio of turns of the two coils, and then the high-voltage electricity is transmitted to the spark plug ignition.

The high-voltage package works in the switch state, and the line excitation tube amplifies the line signal and drives the line tube to make the high-voltage package work, and the high-voltage package is equivalent to a transformer. It outputs several different voltages, high and low. <>

The high-voltage package is the voltage required to increase the counter-path impulse voltage to the anode of the picture tube through the principle of mutual inductance.

The high-voltage package is the most important component of the electrical appliance of the display device, which provides various voltages required by the picture tube, and some also provide pulse signals required by other circuits.

The line frequency current is boosted, and then rectified into a high-voltage direct current of about 20000V through multiple diodes and capacitors, and the structure diagram is used to attract the electron beam emitted by the picture tube electron gun to ensure that the electron beam can be effectively hit on the screen for imaging. The reason why such a high voltage is generated is because the screen must have enough brightness, the faster the electronic movement, the higher the brightness, so the larger the screen, the higher the voltage.

The working principle of the high-voltage package and the TV is basically the same, and its main function is to generate the high voltage of the anode god, and provide various voltages such as focusing, acceleration, and gate. Due to the high voltage package working in the state of high temperature, high frequency, high voltage and high current, coupled with the influence of factors such as humidity or dust in the external environment, the probability of damage to the high-voltage package is high.

2. The high-voltage package is commonly known as the output transformer, and the output of high-voltage direct current is the role of the high-voltage package. This is exactly the same as the high-voltage pack in a TV.
