Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses a high-voltage power supply of a device with a built-in high-voltage power supply and connects one or two or more high-voltage electric wires to one or more high-voltage electric wires directly or through a high-resistance output terminal.
The present invention relates to a high-voltage application type static eliminator which is provided with at least 10 needle-like discharge electrodes or linear discharge electrodes, is installed at a position about 10 cm away from each of the charged objects through a space, and removes the charge of the charged objects at each charged portion.

[0002]

2. Description of the Related Art A conventional self-discharge type static eliminator is installed in contact with or in close proximity to a charged object at each charging site independently of the built-in high voltage power supply to remove static electricity from a charged site of a device with a built-in high voltage power source. Remove static electricity.

[0003]

Conventionally, the static elimination method for a device with a built-in high-voltage power supply uses a self-discharge type static eliminator, so that static elimination is performed only on a charged object on a flat surface. Damage to the charged object or damage to the conductive fibers of the self-discharge static eliminator when the charged object is in contact with or close to the conductive object of the self-discharge static eliminator during sudden or abnormal contact with the moving charged object. There is.

When a metal or conductive object is installed in the vicinity of the self-discharge static eliminator, or when the distance between the moving charged object and the self-discharge static eliminator changes suddenly, the static elimination effect is greatly deteriorated. It should be noted that the static elimination of the three-dimensionally charged object is not suitable, and a part of the conductive fiber of the static eliminator may be cut off and moved to another place to cause various accidents.

[0005] The present invention, despite the fact that the charged object is placed about 10 cm away from the needle-shaped discharge electrode through the space to the charged object irrespective of the three-dimensional shape of the charged object, sudden movement during movement, etc. An object is to provide a static eliminator having a good static elimination effect.

[0006]

In order to achieve the above object, the present invention uses a high-voltage power supply of a device having a built-in high-voltage power supply, and directly outputs a needle-like discharge electrode or a high-voltage electric wire to a high-voltage electric wire through a high resistor. A linear discharge electrode is attached, and a needle-like discharge electrode or a linear discharge electrode is installed at a place where the linear discharge electrode passes through a space and becomes a charged object. The structure of the linear discharge electrode discharges from the side of the thin metal wire.

The needle or linear discharge electrode is attached at a position about 10 cm away from the needle or linear discharge electrode through a space to a charged object.

The above high voltage power supply is used in combination, and one or more circuits for attaching high voltage wires are connected in series or in parallel to the output terminal directly or through a high resistor.

[0009] One or more needle-like discharge electrodes or linear discharge electrodes attached to each circuit of the high-voltage electric wire are connected in series or in parallel.

The distance between the needle-shaped discharge electrodes or the linear discharge electrodes is preferably about 30 cm.

[0011] In order to mount the needle-shaped discharge electrode or the linear discharge electrode, at least the needle-shaped tip portion or the linear discharge electrode is easily opened and installed in an insulating case. It is convenient to have a structure that can change the direction of the tip or the linear discharge electrode.

Preferably, a plurality of needle-like discharge electrodes or linear discharge electrodes are attached to one needle-like discharge electrode or linear discharge electrode mounting case, and the shape is adapted to the shape of the charged object.

[0013]

The electric circuit of the high-voltage power supply according to the present invention is composed of one pole of a high-voltage power supply, a high-resistance, a high-voltage electric wire, a needle-like discharge electrode or a linear discharge electrode, a space, a charged object, and another electrode of a high-voltage power supply. It is a circuit, a high resistance and a space (air electric resistance value is infinite) in the circuit is a series circuit, the electric resistance value of this circuit is infinite, and the circuit current cannot be measured. Since it is very weak, the power consumed by this circuit is also very weak, so it is clear from experiments that even if several circuits of the present invention are used in parallel, the high voltage power supply of the device with a built-in high voltage power supply is hardly overpowered. It became.

Since there is no spark discharge circuit in the electric circuit of the present invention and the circuit current is very weak, no energy causing spark discharge is generated, so that the safety against flammable gas and the like is high.

The electric circuit current of the present invention is very weak and has no energy to ozonize air, so that it is hygienic and safe.

In the present invention, since no ozone is generated, the tip of the needle-like discharge electrode or the linear discharge electrode is oxidized and the tip of the needle-like discharge electrode is not blunted, so that the static elimination effect is maintained for a long time.

The purpose of inserting a high resistance in one pole on the output side of the high voltage power supply is that the continuous time T during which high voltage is discharged is determined by the time constant T due to the capacitance C and the high resistance R of the high voltage power supply itself. = CR
As a result, the continuous discharge time becomes longer, and the time during which the continuous discharge acts on the charged object is also longer, and accordingly, the charge eliminating effect is improved.

When the internal resistance of the high voltage power supply is considerably large, the same effect can be obtained by replacing the internal resistance with the high resistance of the present invention.

Since the present invention is configured as described above, it has the following effects.

According to the present invention, the needle-like discharge electrodes or the linear discharge electrodes can be separately provided, and can be fixed at a position corresponding to the form or charged portion of the charged object, so that effective static elimination can be performed.

Since there is a space between the needle-like discharge electrode or the linear discharge electrode and the charged object, the circuit current is very weak, so that the energy of this current is very weak, so that no spark discharge occurs and the spark discharge is generated. Eliminate fire and explosion accidents.

Since there is no generation of ozone, it is safe in terms of worker hygiene.

Since no ozone is generated, the tip of the needle-shaped discharge electrode or the linear discharge electrode is oxidized, so that the oxide does not adhere or the tip of the discharge electrode portion is not blunted.

Since the static elimination is performed by using the high-voltage power supply in the high-voltage power supply built-in device of the present invention, a high-resistance, a high-voltage electric wire and a needle-shaped discharge electrode (a general needle may be used) as necessary.
Or, only the linear parts of the linear discharge electrode, etc., are much cheaper and more efficient than the self-discharge type static eliminator attached to the place where the conventional self-discharge type static eliminator is charged. It is possible to eliminate electricity at various places about 10 cm away from the object.
