Description

CHARGING AND DISCHARGING EDUCATIONAL FIXTURE UTILIZING TRIBOELECTRICITY}

The present invention relates to a charging and discharging fixture for education using triboelectric electricity, and more specifically, by directly identifying and recognizing the electrostatic discharge phenomenon caused by the generation and accumulation of triboelectric electricity. The present invention relates to an educational charging / discharging jig using triboelectricity, which can lead to a natural consideration of the problem and the countermeasures against the discharge phenomenon caused by the generation and accumulation of static electricity in the industrial field and life.

Static electricity can be defined as electricity with little spatial movement of charge, so that the magnetic field effect caused by two currents is negligible compared to the electric field effect. Occurs due to adhesion, radiation, transformation, chemical changes, etc. Static electricity leaks at the same time as it occurs, which is called 'relaxing', and the accumulation of static electricity on an object subjected to friction is called 'charging'. The slowness is caused by the flow of electricity, and when the amount of loosening is large, it is not a problem when the charging amount is small. On the contrary, when the amount of loosening is small and the charging amount is large, a momentary discharge phenomenon occurs. .

The voltage during the momentary discharge of static electricity in daily life is typically in the range of several thousand V to tens of thousands of V, but the current of static electricity is only 1,000 to one millionth of the current used in daily life. It does not cause

Static electricity is most severe in dry seasons with 20-30% humidity or in winter. In summer, when static humidity is 60% or higher, the static electricity tends to be lowered by the slowing of the static electricity into the air.

About 25% of the total population complains of static electricity discomfort during the transitional season or winter, and in severe cases among people or elderly people with dry skin, physical contact with objects as well as physical contact with others Sometimes it's enough to avoid it.

Most of the damage caused by static electricity in everyday life is not intense enough to lead to lightning strikes, but it is also a cause of secondary disasters such as falling or falling from heights due to shocks from lightning strikes. It may also cause a decrease in productivity due to the back. On the other hand, in people with dry skin, people suffering from skin diseases or diabetes, elderly people, weak or overworked people, static electricity has been reported to irritate the skin to cause inflammation or worsen to adversely affect health.

On the other hand, in the industrial field, the electrostatic phenomenon is used in various fields, for example, the electrostatic painting field, the printing and copying field such as the electrostatic magnetic roller of the copier, the food packaging wrap field that is easily adhered by static electricity when drawing out. have.

However, even in the industry, the damage of static electricity can be very serious, for example, in the storage and transport of flammable materials, static electricity can cause explosion, entanglement of the thread by the attraction force or repulsive force of static electricity, clogging by dust, It is the main cause of mechanical production failures such as printing stains, product contamination, etc., and the discharge current generated during electrostatic discharge can cause serious problems such as destruction or malfunction of electronic components such as semiconductor devices. Electromagnetic waves cause malfunction or noise of electronic devices or devices, and light emission generated during discharge causes damage such as photosensitive photographic films.

Since the negative charges of the first electrode 10 and the positive charges of the second electrode 20 are close to each other, the suction force acts, so that the positive and negative charges are discharged even if the battery (not shown) is removed or the friction is stopped. 2 electrodes 10 and 20 (or the first and second electrode plates) remain as they are and are charged.

The capacitance (C) of the capacitor increases as the area of the opposing first and second electrodes 10 and 20 increases, and as the separation distance approaches, the dielectric between the first and second electrodes 10 and 20 increases. When the plate 30 is interposed, the electrostatic induction action (in an electric field state, the electric dipoles in the dielectric are randomly distributed and exhibit the same properties as an insulator, but when an electric field is generated by applying a voltage to an electrode, The positive and negative charges are induced by the polarization action aligned in the direction), and thus the charges of + and-are generated in the dielectric plate 30, resulting in the first and second electrodes 10 and 20 approaching each other.
