How can there be induced electricity in the quilt Why is there induced electricity?

It is not inductive electricity, but static electricity, which is dry in winter, causing the quilt to rub and easily electrify.

It should be static electricity, not induction electricity.

The specific reason may be that your ** is not cotton, containing chemical fiber components** is easy to produce static electricity, or the room is too dry, and the air is dry and easy to produce static electricity, and you can use a humidifier to increase the air humidity °

In winter, it is dry, and there is static electricity in the quilt, which may be because the quilt material used is not pure cotton. We can choose some quilt materials with a relatively high degree of pure cotton, and to maintain the humidity of the air humidity, you can put a small basin of water indoors, or use some accelerators to keep the humidity in the room moderate, or you can sprinkle some water at home in the dry air, which can improve the indoor air humidity. In addition, the quilt is prone to static electricity, and it may also be because the quilt is not changed frequently, so it may be necessary to change the quilt frequently and put some fabric softener in the quilt, which can effectively prevent static electricity.

There is induced electricity in the quilt, and you are talking about static electricity.

In winter, the weather is dry, and the friction of objects is prone to static electricity. Especially chemical fiber items.

You can replace them all with cotton items, or use a humidifier in the house, and there won't be so much static electricity.

If there is electricity in the quilt, it should be dry** with the quilt fabric or quilt inner core is the static electricity generated by the chemical fiber material, not induced electricity.

Static electricity generated by hair or sweaters rubbing against the quilt.

It is not induction, it should be static electricity, and the chemical fiber fabric will be triggered, if you want to avoid it, you can replace it with a pure cotton fabric.

In winter, the friction of chemical fiber items will produce static electricity, such as down jackets, quilts, storm shirts, assault suits and other items.

This cotton picker has a good charged nature, so there will be a bit of an electrical illusion, the electrostatic ring is rubbed out, the good point of the cotton will be very few, and the second point is generally mixed with synthetic things.

That's not called induced electricity, it should be static electricity, it's static electricity generated by friction!

Choose cotton fabrics for clothing and home accessories, and avoid using chemical fiber carpets and furniture with plastic as the surface material to prevent frictional electricity. Stay away from electrical appliances such as televisions and refrigerators as much as possible to prevent inductive electricity.

Maintain a certain humidity indoors: when the relative humidity of the air exceeds 75%, it generally does not produce static electricity, and when it is lower than 40% and 50%, the static electricity is not easy to escape, and it is easy to form high potential. Therefore, it is necessary to mop the floor frequently, sprinkle water frequently, or humidify it with a humidifier.

Induced electricity is a type of electricity carried on the outside of a conductive device. General studies have shown that the human body is more sensitive to electrostatic induced currents under high-voltage electric fields, and when milliampere induced currents pass through the human body, even if the induced object is not touched, the person will have a significant pinprick sensation.

It is best to plug the computer directly into the wall power socket, because most of the multi-purpose socket strips are not connected to the ground wire, which can ensure that the induction is eliminated. The power plug of the DVD player is bipolar, and if the quality is not too high, it cannot be eliminated.

The induced electric voltage is very low, generally not exceeding the safe voltage of 36V, so it will not cause harm to the human body.

This is simple,Many people will notice,When adjusting the TV antenna,There will be a slight numb electric sensation in the hand,If you touch the antenna and the aluminized knob with the voltage tester,You can also see the neon bubble glow,This means that the antenna and knob are charged。

It doesn't matter, the induction is due to the induction of the voltage detector around the line of fire or other electrostatic fields. Because static electricity can generate electrostatic potential through the air and form an electrostatic field through the human body, this electrostatic field crosses the resistance of the voltage tester and passes directly through the neon bubble of the electric pen, causing the neon bubble to glow.

This electricity is very weak and basically harmless. If you rub it with a rubber rod to generate static electricity, you can also make the voltage tester glow.

"DVD player, computer host, etc., will have a little induction", that is, your home power socket is not grounded or not pulled ground, and the ground wire is connected to the metal shell of the electrical appliance through the plug. The solution is to re-draw the ground wire.

Induced electricity:

The essence of induced electricity is to change the distribution of electrostatic charges in space through certain methods.

A metal is introduced into the electric field (because the metal contains free electrons in it).Due to the action of the external electric field, the free electron movement that originally did thermal motion will have a tendency, and finally reach a new equilibrium state (of course, this equilibrium state is related to the external electric field), and the free electrons in the metal will change from the original uniform distribution to non-uniform distribution. So from the outside it seems that an electric charge is generated, but the positive and negative charges produced are always the same because the charge is conserved.

Static electricity: The nucleus of various substances has different binding ability to electrons, so the ability of substances to gain and lose electrons is also different, which causes various charged phenomena such as triboelectric conduction.

Answer: Induce electricity.

It cannot be eliminated for the time being, but there are several ways to reduce or absorb some of it.

At both ends of the relay coil, a diode is connected in parallel in reverse direction.

It can absorb induced electricity of about 8V. This method cannot induce electricity, but it can absorb most of it.

Connect a 1k resistor in parallel at both ends of the relay coil.

Ground the 0V of the switching power supply.

Check the control circuitry to avoid possible side-by-side routing with high-voltage cables.

Do a good job of grounding. and capacitance of about 1uf.

Introduction: Induced electricity is the electricity carried by the outside of a conductive device. Generally speaking, there is no harm to the human body. Induced electricity has a greater impact on more sensitive electronic devices, such as pacemakers.

Therefore, people equipped with such instruments must pay attention.

Explanation: Induced electricity is electricity that is commonly found on the outside of conductive devices. The essence of induced electricity is to change the distribution of electrostatic charges in space by certain methods, the biggest example of which is the introduction of a metal into an electric field (because the metal contains free electrons.

Due to the action of the external electric field, the free electron motion that was originally thermally moved will have a tendency, and finally reach a new equilibrium state (of course, this equilibrium state is related to the external electric field), and the free electrons in the metal will be evenly distributed from the original.

It becomes unevenly distributed. So from the outside it seems that an electric charge is generated, but a positive charge is generated.

And the negative charge is always the same because the charge is conserved. In general, there must be switching power supplies and filters in the control system, and they all have Y capacitors in them.

That is, a 220V to ground (enclosure) capacitor, if your system is not grounded, then the enclosure will have 110V AC voltage.

I've also encountered strong induction electricity, and it's no problem to do a good job of grounding! When I make machines now, I require the electrician to do a good job of grounding, so that both the safety and the operation of the machine will be much more assured!

I'm working on this as well. There is no ** way to do it at the moment. If it is a DC relay, several methods have a certain effect.

1. At both ends of the relay coil, a diode is connected in parallel (positive connection will be short-circuited), which can absorb about 8V induced electricity. This method cannot induce electricity, but it can absorb most of it.

2. Connect a 1k resistor in parallel at both ends of the relay coil.

3. Ground the 0V of the switching power supply.

There must be a switching power supply and a filter in the system? They all have a Y capacitor in them, which is a 220V capacitor to ground (case), and if your system is not grounded, then the case will have 110V AC, which is not surprising.

Put a capacitor of about 1UF on the coil of your indicator light, and you're good to go!

The control loop of the soft starter, the control loop looks fine.
