What s the deal with the fact that home circuits are always muffled indirectly?

Friend, it is caused by the leakage of electricity in your line, and it must be checked and dealt with in time, otherwise it will lead to serious consequences.

There may be leakage in the circuit, and the discharge phenomenon will be accompanied by the moment of power-on. It is recommended to overhaul the circuit.

What is happiness? What is happiness? In fact, there is no absolute answer to happiness, the key lies in your attitude towards life.

Only those who are good at grasping happiness know what happiness is. I always thought that it was very difficult to feel happiness, and that was a state of light. After the passage of time, I realized that happiness is actually very simple, as long as the soul is satisfied and comforted, it is happiness.

In fact, happiness is not in the distance, nor in the dream, it is around me, in my daily efforts, in every minute of love, and in every second of anticipation. Happiness is sometimes like air, everywhere, just getting used to its presence without knowing it. Just as you are now happy to sit together as a family and eat dinner happily; It is happiness to see the person you like when you don't expect it; Work is smooth, family health is healthy, this is also a happy ......In fact, sometimes you are feeling happiness, you just don't know it.

Happiness is actually like old wine, which needs to be tasted slowly. When you turn off the TV, computer, and mobile phone, you sit quietly on the balcony and look out the window, thinking about the past over the years, and the scenes that come to your heart, although there is joy that makes you taste the taste of joy, there is sadness that makes you feel heartache so far, there is the regret of "Xinsong hates not a thousand feet", and there is a lament ...... "I can't throw tears for this".But in any case, it is enough to have walked without regrets, this is a faint happiness.

Happiness is actually all around us, but we often ignore the happiness that is within reach and take it for granted. When I didn't get into college, I thought that I would be happy if I was admitted, and when I was really admitted, I found out that it was the same thing. When I was in school, I thought that I would be able to get rid of my worries after graduation, but when I graduated, I found that I couldn't even find a job.

When I didn't have a job, I thought that everything would be fine if I got a job, but when I worked, I found that life was still so boring. When I didn't make money, I thought that if I could have 2,000 yuan a month, I would be satisfied, and I didn't feel very happy when I got a job of 3,000 yuan. Half of each month's salary is used to pay off the loan.

When you're not in love, you feel good to have someone by your side; When I'm in love, I don't seem to be so free. I want to get married, I want to get married, everything is stable, it's good; Get married, it turns out that marriage is just life. Life was originally firewood, rice, oil, salt, sauce, vinegar and tea.

So, if you want to feel happy, you will feel happy. Happiness is subjective, and happiness is to be felt. Cherish the happiness in front of you.

A short circuit in a circuit may be caused by the aging and wear of the insulators outside the live wire and neutral wire, resulting in a loop in which the live wire and neutral wire stick together. Since the resistance of the live and neutral wires is much smaller than that of the consumer, the current does not pass through the consumer, but directly through the new circuit, resulting in a short circuit.

Whether the electrical appliance is wet, or the high-power electrical appliance does not have a grounding wire.

Overload of electricity, line and electrical insulation aging.

1. Short circuit caused by aging of the line and damage of insulation; 2. The power supply is overvoltage, resulting in insulation breakdown; 3. Small animals (such as snakes, hares, cats, etc.) are crossed on bare wires; 4. Caused by a variety of man-made random pulling; 5. The line of the outdoor overhead line is slack, and it collides under the action of strong winds; 6. The line is installed too low, and it collides with various transportation items or metal objects, resulting in a short circuit.

Hehe, 1. Leakage of household appliances, 2. Water ingress or moisture in the junction box, 3. Serious aging of wires 4. Useful electrical appliances have been damaged, resulting in a short circuit. 5. The wire has a joint, and after a long time, the aging of the adhesive tape causes a short circuit. 6. Artificially caused a short circuit in the line.

1.There was thunder.

2.It's raining.

3.Here comes the rats.

4.A typhoon is coming.

5.**Finish.

6.The man was electrocuted.

Or not?

The "Technical Regulations for Electrical Installation" stipulates that the installation of lighting circuits must be "live wire into the switch, ground wire into the lamp head". Some people think that it doesn't matter, as long as it can play a control role, so many families have fan governors and light switches connected to the zero line. When the switch is disconnected.

However, there is a neutral line disconnection fault, and the live wire passes through the load so that the neutral line in the front section of the breakpoint has a phase voltage to the ground. An electric shock accident occurs when a person touches it.

In recent years, most of China's families have added air conditioners, refrigerators, electric water heaters, rice cookers, electric frying pans, electric kettles, etc., and the electricity load has increased dramatically, while the indoor power lines are still designed and installed in the late 60s, and the amount of wire ampacity is large. Due to severe overload operation, the blade fuse is often blown out, and some people use copper wire as a fuse once and for all. As a result, when the load exceeds the standard, the fuse does not blow, resulting in an aging and short circuit of the line insulation.

Grounding protection is to connect electrical equipment. The metal casing of the appliance is reliably connected to the earth. In the event of a leakage fault, the dangerous voltage of the shell is safely leaked into the earth to ensure personal safety.

The electrical grounding must be connected to a dedicated grounding wire. Some families use water pipes as ground wires to save trouble. This is dangerous because the water pipes are made of iron, and the joints between the pipes are sealed with hemp wire or raw tape.

The use of water pipe as the grounding wire, the grounding resistance is too large, can not meet the grounding requirements, and does not meet the safety regulations.

That's about it.

It may be the sound of thyristor and capacitor discharge, and the filtering is not done well.

The wires are connected to each other, that is, the wires are connected to each other, because the joints are not good enough, the effective cross-sectional area of the wires is relatively small, according to the determinants of resistance, the smaller the cross-sectional area, the greater the resistance, and then according to Q I2RT, when the current time is equal, the resistance is large, and the heat is generated, which is more likely to heat up than elsewhere and accelerate aging.

It must be caused by the high resistance.

Because the connection is conducted by the contact surface of the two wires, its resistance must be greater than the original.

Then the degree of heat generation is determined by power, power = the square of the current multiplied by the resistance, the current is basically fixed, so the resistance is large, the power is large, and the heat is also large.

1. The resistance of the wire connection must be less than that of the wire, which is easy to heat and age.

2. The contact surface of the wire will be loosened, oxidized, corroded, and caused by poor contact, which is more likely to heat up, and a vicious circle.

There are several possibilities for this:

1.These two live wires are two-phase electricity, then their voltage is 380V, which is the rated voltage of general household appliances.

It's 220v, so when you connect the appliance between these two wires, the appliance burns!

2.These two live wires are two wires drawn from one phase electricity, then the voltage between these two live wires is 0V, and the electrical appliances are connected between these two live wires, and the electrical appliances do not work.

3.These two live wires are a live wire and a ground wire, but with a test pen.

When the ground wire is measured, the voltage is induced to make the test pen shine, and when you connect the electrical appliance between these two live wires, the electrical appliance can work normally.

Some appliances with 220v may be burned.

There are two reasons, one is overload, and the other is a short circuit in the electrical appliance.

If the appliance is not connected incorrectly, there may be leakage.

One is a short circuit, and the other is an overload of the circuit.

Except for CCTV's ** station, which seems to be stereo, ordinary TV signals are mono. When it is good to use ***, it means that your connection is fine, and the amplifier can decode and promote the speaker to sound normally, which also means that your speaker is good. So what is the problem?

It's very simple, what you have to figure out now is that surround, center, subwoofer, etc. are all independent channels, and it only sounds when there is a signal, and it has no sound when there is no signal. Unless the sound field is set by the amplifier, the ambient mode can make all the speakers sound the same at the same time.

Then your TV can't be a multi-channel output,And you say that there is sound around the center when connecting to the TV,That means that there is a problem with the connection between your TV and the power amplifier,From the TV to the power amplifier, you should use the two-channel connection cable to access the two-channel input of the power amplifier to be OK。 When watching TV, you need to change the input on the amplifier to the corresponding interface to be correct.

Hello, simulated environment does not kill progesterone.

Swap the output and input cables of the left and right channels and try it.

You see if the wire that is output to the amplifier is broken If not, it is the amplifier A certain channel is broken Find a professional maintenance personnel to repair it Don't punch in and open it There is high voltage in it It is very dangerous.

The signal cables, plugs, and sockets of the right channel have poor contact.
