Can 170 volts of direct current directly electrocute people?

Not necessarily. Static electricity can be as high as tens of thousands of volts, but because of the short time, people do not die.

But not necessarily if it's a long time.

The safe voltage of the human body is not higher than 36 volts.

The current allowed by the human body is 9 mA for men and 6 mA for women; The human body can get rid of the current of 76 mA for men and 51 mA for women; The current that causes ventricular fibrillation is about 1300 mA when energized for seconds and about 500 mA when energized for 3 seconds.

**When dry, the body resistance is about 6 10k

i=u/r=170v/10000ω=

But if the body surface is not dry after sweating, the tissue is only 100 i=u r=170v 100=

Enough to choke. It depends on the situation, so it's hard for anyone to say.

In fact, electric shock is a mixed relationship between voltage and current. It is not right to talk about voltage alone, and it is not right to talk about current alone. Generally speaking, we think that a voltage below 36V is a safe voltage, but if the voltage below 36V passes through a large current, it will also electrocute people.

In fact, electric shock is a matter of power. As long as the energy is less than the value that our human body can bear, the voltage of 170V will not electrocute people. I have often been charged by 220V household circuits, as long as the time is very short, it will be retracted quickly, and it will not be life-threatening.

Standard of safety voltage: When electrical equipment needs to use safety voltage to prevent electric shock accidents, different levels of safety voltage ratings listed in this standard should be selected according to factors such as the use environment, personnel and usage methods.

This standard is not applicable to special places such as underwater, nor is it applicable to medical equipment with live parts that can extend into the human body.

The "Safe Voltage" in this standard is equivalent to the "Safety Extralow Voltage" in the International Electrotechnical Commission publication

A safe voltage is a series of voltages powered by a specific power supply to prevent electric shock accidents. The upper limit of this voltage series, in any case, between two conductors or between either conductor and ground shall not exceed the AC (50-500Hz) RMS value of 50V.

Note: In addition to the use of independent power supply, the input circuit and output circuit of the power supply of safety voltage must be isolated from the circuit. Circuits operating at safe voltages must be electrically isolated from other electrical systems and any unrelated conductive parts. The upper limit of direct current will be supplemented at a later date.

Direct bodily injury.

Injuries to persons caused by the action of the electric current itself.

The safety voltage ratings are 42, 36, 24, 12, 6V.

When electrical equipment uses a safe voltage of more than 24V, protective measures must be taken against direct contact with live bodies.

Additional note: This standard is proposed by the Ministry of Labor and Personnel.

This standard is drafted by the Beijing Institute of Labor Protection.

The main drafters of this standard are Zhao Luzhen, ** Ji, Liu Xiuzhen and Cui Guozhang.

Above 36V is dangerousIt doesn't matter if it's DC or AC.

By the way, do DC and AC landlords know?

If it's not clear, just take a look at the following, and if it's clear, I'll be okay if I didn't say it.

Alternating current, abbreviated as "alternating current". Generally refers to a voltage or current whose magnitude and direction change periodically over time. Its most basic form is a sinusoidal current.

The standard frequency of AC power supply in China is 50 Hz. The form in which alternating current changes over time can be varied. Different variations of alternating current have different application ranges and effects.

Sinusoidal alternating current is the most widely used, and other non-sinusoidal alternating current can generally be mathematically processed into the superposition of sinusoidal alternating current. "

Direct current flows in a straight line"

If you grab the charged body and can't get out of it within tens of seconds, you will die, women should be faster, if you are only hit by electricity, it will not hurt, you are afraid that you can't get rid of it, 36v electricity doesn't kill people, who doesn't believe that you can try it with your teeth, someone in our unit moved the bar, and the result was a human life, and it was still fatal after a long time, remember.

Exceeding 36v is a bit dangerous.

It is not absolute, some old electricians have a great resistance in their hands, and they say that they do not need to pull the switch to repair electrical appliances. It's rare to be charged by 220V alternating current, but it's just a little numb!

170 is dangerous! It can be said that it is not much different from 220, it is more than 36V a lot.

36 volts is a safe voltage, and there is danger if you exceed this. The usual dry battery is yes, and the electricity used for lighting is 220, which is dangerous to people.

Yes. The safe voltage for the human body is less than or equal to 36 volts.

The safe voltage is 36 volts for sure

You can give it a try!

The safe voltage for people is not higher than 36V!

It depends on where the electricity is.

220V household electricity electrocuts people.

The industry stipulates that the safety voltage is not higher than 36V, the continuous contact safety voltage is 24V, and the safety current is 10mA. The degree of harm to the human body of electric shock mainly depends on the size of the current passing through the human body and the length of the power on time.

The greater the current intensity, the greater the fatal danger; The longer it lasts, the more likely it is to die.

The minimum value of current that can be perceived by a person is called the perceived current, which is 1 mA for AC and 5 mA for DC; The maximum current that a person can get rid of after an electric shock is called getting rid of the current, which is 10mA for AC and 50mA for DC; The current that is life-threatening in a relatively short period of time is called a lethal current, such as a current of 100mA passing through the human body for 1s, which can be enough to make a person fatal, so the lethal current is 50mA.

In the case of protection against electric shock, the current allowed by the human body can generally be considered as 30mA.

DC and AC are the same, both can electrocute people. It's just that DC can only be electrocuted by connecting the positive and negative electrodes, while AC only needs to be in contact with the earth to be electrocuted. Direct current cannot form a circuit with the earth, so it is relatively less likely to cause electric shock accidents.

How to Prevent Electric Shock Accidents:

1. Install leakage protectors:

The leakage protector is a safety device that can automatically cut off the power supply when the current leaks to prevent the occurrence of electric shock accidents.

2. Avoid using electrical appliances in a humid environment: A humid environment can easily lead to electrical leakage, which increases the risk of electric shock.

3. Do not use electrical appliances in water: water is a conductor of electricity, and contact with water should be avoided when using electrical appliances.

4. Do not use when the electrical appliance fails: If the electrical appliance fails, stop using it immediately and ask a professional to overhaul it.

5. Avoid using damaged wires and plugs: Damaged wires and plugs can easily lead to current leakage and increase the risk of electric shock.

6. Do not use electrical appliances in thunderstorms: thunderstorms are easy to cause lightning strikes and increase the risk of electric shock.

7. Learn how to use electrical appliances correctly: Correct use of electrical appliances can reduce the risk of electric shock, and you should learn the correct way to use them.

8. Regular inspection of electrical appliances: Regular inspection of electrical appliances can find potential safety hazards and repair and replace them in time. <>
