How to use an electrostatic generator? What is the principle of an electrostatic generator?

Summary of the application of electrostatic generators;

1. The steel plate is laminated and paper-covered, and the Fraser7360 electrostatic generator can be equipped with the corresponding electrostatic generator.

2. For in-film labeling, the Fraser7360 electrostatic generator and the 7090 single-point electrostatic generator can be used.

3. Cast film edge positioning, using FRASER 7360 electrostatic generator and claw type electrostatic generator, etc.

The most commonly used electrostatic generator should be good Yatong, first of all, it is necessary to rub the electrostatic gun grounding wire in the electrostatic discharge generator firmly and fix it with the subway board, if the connection is not firm, the danger is very large; The second is that the test is placed on a table covered with a white insulating board, and it must not come into contact with a metal conductive object.

Once the device is in place, the next step is to set the parameters of the ESD generator. First of all, you need to turn on the power supply of the electrostatic discharge generator, start the boot screen at the same time, and set the parameters, the discharge mode of the electrostatic discharge generator is divided into contact discharge or air gap discharge, and before the polarity switching, you need to select no in the menu of high voltage power-on, and then you can switch between positive and negative voltage; There are four discharge modes to choose from, as well as other parameters such as voltage setting, number of discharges, time intervals, and discharge standards.

When a negative voltage is applied to the discharge electrode via DC high voltage, an electrostatic generator (also known as a meltblown cloth electrostatic electret device) produces a corona discharge, at which time the resulting negative ions (-) fill the dust particles in the gas and apply a positive voltage through electricity. It uses the principle of electrostatics, which is collected by moving to the dust collection bar.

Ionization and discharge.

In order to use the electrostatic principle of an electrostatic generator, it is necessary to understand the basic concepts of ionization and discharge.

1) Ionization. Electrons far away from the nucleus receive energy such as heat and light from the outside, and the energy increases (excitation) and may soon escape from the nucleus. This separation of the electron from the nucleus is called ionization and acts as a conductive electron as a free electron. Conductive electrons move freely between metal atoms.

2) Discharge. Discharge is a phenomenon in which an insulator loses its insulation under a strong electric field and an electric current flows through. The discharge is divided into unsustainable discharge with the current between the electrodes is "0" and discontinuous discharge without external ionization, continuous discharge is partial destruction, corona discharge and spark are obtained, positive corona and negative corona are obtained. It is divided into flame discharge, glow discharge, and arc discharge, among which the converter can be damaged.

Corona discharge. Unlike metal conductors, the electrons that can move freely in the gas are very small, so they usually remain insulated and barely charged.

However, if a high voltage is applied to the dust collector electrode and the discharge electrode, a potential difference occurs between the two poles and ionization, in which free electrons are generated and a fine current flows.

If the electric field is strengthened by continuously applying voltage, the insulation breakdown strength that can destroy the insulation state is reached, and if only the majority of the electric field emits light and sound through a sharp shape such as a bed, the insulation state will be partially destroyed. This is called a corona discharge.

1) Return corona.

When the resistivity of dust adherence to the surface of the dust collector electrode is very high (above 10q-cm), the collector electric field is strengthened by the current flowing through the dust layer, and the electric field of the discharge electrode is weakened, and the discharge electrode field is weakened. This refers to a phenomenon in which a large number of ions are generated from the breakdown point of the insulation through a fine dust gap to neutralize the negative ions, thus reducing the efficiency of collection.

2) Entrainment again.

On the other hand, re-entrainment, on the contrary, if the specific resistance of the dust is too low, below 10q-cm, then the electrons are easily discharged even if they are lost by the power collection in the dust collection plate and the binding force between the particles and the collection plate, resulting in the polarization of the dust particles. Re-entrainment occurs in the return space, which also reduces the efficiency of dust collection.

The basic principle of all kinds of electrostatic generators is the same: by a stable DC power supply (composed of a step-down circuit, a rectifier filter circuit, a voltage stabilization circuit) to provide energy, through self-excited oscillation (generated by an oscillating coil or integrated circuit), it is converted into a frequency of 5kHz 20kHz, and boosted to 6kV 10kV alternating power, and then through multi-stage (generally 10 levels, there are also 12 levels) pressure rectification, you can obtain a 60kV 100kV high-voltage DC source - high-voltage electrostatic.

The electrostatic generator is composed of an electrostatic emission rod and a DC high-voltage power supply. The DC high-voltage power supply is supplied to the electrostatic emitter with negative (or positive) high voltage, so that the electrostatic emitter rod emits negative ions (or positive ions) and then imparts an electric charge (artificial charge) to the object (workpiece). The higher the voltage, the greater the effective range.
