What were you thinking about the moment of the sudden power outage?

At the moment of a sudden power outage, of course, I wonder, why is there a power outage at this moment? Could it be because of some natural disaster that the school has suffered? Or that there is something big wrong with the school's electricity, in fact, at that time I was more worried and afraid, because we all know that in this era, there is no TV, it is not possible at all, we go to class every day, and the basic verbal communication has to be through the Internet, mobile phones and other electricity-related things, so I am very desperate at the moment of power failure.

At the moment of the sudden power outage, the most thing I think about is when to call, after all, my mobile phone is almost out of battery, so I will keep thinking about these, I can't solve the problem at all, in addition, if my mobile phone is also out of power, I will think, people come from **?

When the power went out in high school, I was very happy in my heart, hoping that it would be out all the time, so that I didn't have to study at night, and I could have a good rest and relax my tense nerves. Maybe the power outage is too long, the canteen can't cook, and the school has to give a holiday.

At the moment of the sudden power outage, I think many people's first reaction is, ah, why is it so dark! Then the next moment you will think what to do if there is no power, is the battery of the phone enough? When will I call again? If I don't get a call, how long will my phone last?

At the moment of a sudden power outage, I will think about how the power suddenly goes out, I will be startled first, and then think about whether my mobile phone has power and how long it can support it, and then see if the power bank has electricity, and I will also think about what I can do when there is no electricity, and when will the electricity come.

When I was studying at night in high school, there was a sudden power outage, and I heard everyone in unison "Huh" in front of me, and some students shouted "power outage" in a cheerful tone, and I was thinking: Oh, I can finally rest, and if the dormitory building has a power outage, can I go back to the dormitory to sleep directly, don't call.

When there is a sudden power outage at home, you will think: will the things in the refrigerator melt away, how to play without wifi data is not enough, hurry up and call!

Suddenly the power went out my first reaction was to find the phone, and when I found the phone, I would go to find a candle, there must be a long time of light for me to see, otherwise I will feel very panicked in my heart, I am the most uncomfortable in the dark night, I must let myself see the light illuminated, such as my life in general, can not be a dark, even if it is dark, there is a light of its own.

When I was a child, because I was in the countryside, maybe the conditions couldn't keep up, I felt that there was always a power outage at home, and then every time there was a power outage, I would wonder if the world would be destroyed like this, if there was no electricity in the world in the future, would we return to the primitive society.

There are many reasons for sudden power outages, the most common being line repairs, arrears, and line breaks.

There are many reasons for a sudden power outage, such as:

1.Typhoons, torrential rains, thundershowers, etc., due to weather and climate issues, are the most common causes of power outages.

2.For example, if lightning strikes electrical equipment, transmission towers, power lines, and utility poles in your area, a power outage may occur.

3.Theft of a power line in operation can lead to power outage failures.

4.There is a possibility of power outages due to collisions between vehicles and power poles, as well as damage to underground cables due to construction excavations.

5.While electrical equipment is guardrailed to prevent animal vandalism, rats and other small animals can still cause short circuits in electrical wiring.

6.When some customers fail, if there is no fault isolation facility or the isolation facility fails, it may cause the entire line to lose power, and affect the power supply of this line to other users.

7.During high winds or if trees are not pruned in time, tree branches may come into contact with power lines, resulting in power outages.

8.In the hot summers, unusually high power demand due to unusually high heat can melt overloaded cables, transformers and other electrical equipment.

9.In mid-September this year, industrial enterprises in 20 provinces such as Jiangsu, Zhejiang, Liaoning, Guangxi, and Yunnan were required to stagger peak power consumption, and the scope of power restriction even exceeded the scope of industrial and commercial electricity consumption, resulting in daily electricity consumption and normal operation of residents.

Why blackouts.

Typhoons, heavy rains, etc. are the most common causes of power outages.

Power outages can occur if lightning strikes power equipment, transmission towers, power lines, and utility poles.

When a running power line is stolen, it causes a power outage.

Power outages may occur due to vehicles colliding with power poles or construction excavations damaging underground cables.

If it is not in arrears, it may be a line failure, it may be that the road section is detected or there is some obstacle that damages the power line, if you have electricity in your neighbor's house, it must be your home appliance arrears or your home appliance switch tripped, just include the switch.

A sudden power outage indicates that the power supply line is faulty, or the power outage is caused by line inspection and emergency repair.

The normal indoor voltage is 220V, if the voltage at home does not reach the normal 220V voltage, or install a voltage regulator to reach the normal voltage.

The causes of sudden power outages are: sudden power supply line failure, power outage in arrears, and low-voltage fault power outage.

1. Sudden power failure of power supply line.

Electricity from the power plant through the transmission line, substation to the user's home in many links, any link failure, damage by external forces, or irresistible natural disasters, will cause power outages. If there is a sudden large-scale power outage, it is likely that the power outage is caused by a sudden fault of the line.

2. Power outage in arrears.

If the customer fails to pay the bill in time within the specified payment period, the relevant part will take power outage measures against it according to the relevant basis, and the customer needs to go to the bank to settle the electricity bill in time and ask for the electricity invoice, and then inform the contact person according to the contact ** provided on the arrears notice, and the power supply can be restored only after completing the relevant procedures.

3. Power outage due to low-voltage fault.

Some people increase electrical equipment without permission, and the over-capacity use causes transformers, switches, watt-hour meters and other electrical components to burn out. Power outages will be caused by internal equipment failures such as main gates and opening gates, broken wires in the building, and tripping of air switches.

There is a sudden power outage, it may be that the electricity bill is gone, or it may be that the outside line is being repaired, so the power is out.

Either the bill is in arrears, or the air switch of the meter has tripped, or the power company is repairing it.

You smile the most beautifully, with two thin lips smiling, long eyes smiling, and two sunken dimples on your cheeks.

If there is a sudden power outage, it may be that your electricity bill is in arrears, there may be a problem with the line, or it may be a local power outage.

The reasons for the sudden power outage are as follows:

1. Only your own home has no power.

It may be that the power of household appliances is too large, exceeding the carrying capacity of household lines, causing tripping;It may also be a short circuit in household appliances, such as aging wiring, water ingress into electrical appliances, etc.;There may also be arrears, as long as you pay the bill, you can call. By the way, the anti-plug card can also advance 10 yuan for electricity. Tips:

After a power outage due to arrears, you should first reverse plug and recharge to avoid recharge failures.

2. There is a power outage in the neighborhood, or in the community.

This type of reason is generally the failure of the internal line equipment in the community. At this time, the property electrician needs to focus on inspecting key equipment such as power distribution rooms, transformers, and cable joints.

3. Multiple communities, or large power outages.

Power outages carried out by regular "medical check-ups" of power grid equipment. According to the operation cycle and status evaluation results of power grid equipment, the power supply company will carry out planned maintenance and overhaul of the equipment for power outage and maintenance.

For this type of power outage, the power outage construction plan will be reviewed and optimized in advance, the power outage time will be reduced, and the information will be notified in advance. The power supply company will also choose the residents' working hours for maintenance, or choose the trough of electricity consumption, such as starting the operation in the early morning, to avoid affecting the electricity consumption of residents as much as possible.

Other situations of power outages

Temporary suspension: If it is found that there are accidents such as disconnection of the line, it is necessary to immediately cut off the power and deal with it, or cooperate with the first to carry out unforeseen projects such as emergency rescue; During peak hours, there is a "stuck" phenomenon in the power supply, and an emergency power outage may also occur.

Fault tripping: such as hitting the bar, breaking the line, inverted rod, inverted tower, etc. caused by bad weather that need to be dealt with urgently; Or in the process of power generation and transmission, equipment failure, may lead to unplanned failure power outage.

at homeappearedThe cause of the partial power outage: grip the trouser skin

1. The load is too large, and the air switch trips

If the indoor power supply is restored after closing the gate, but after a few minutes there is a trip, you can turn off some high-power electrical appliances to see if there is still a tripping phenomenon, if it will not trip, it means that the power of the indoor load exceeds the range of the empty opening threshold. When this happens, it is necessary to replace the air switch with high current.

2. The zero line row burns out

If the indoor light has electricity, and the leakage protector has not tripped, the socket is out of power, it is likely that the indoor neutral line is faulty, and when this happens, replace the new zero wire row.

3. Circuit problems

If you can't push it up after tripping at home, you need to unplug all the sockets in the room, and check which electrical appliance is causing the short circuit one by one. First of all, all the empty open is closed, and push up one by one in order, if there is a certain empty open push up immediately after tripping, it means that the electrical appliance has a short circuit, and then the maintenance can be.

Optionally, the air switch can be replaced or the power cord can be repaired. Because the partial power failure at home is caused by the damage or tripping of the switch of a certain branch, it is necessary to check whether the switch of each branch has the above two phenomena and repair it in time.

Power Outage Emergency Measures:

1. In case of a power outage, you should use flashlights and other lighting tools to first check whether the internal power distribution switch and leakage protector are jumped.

2. If there is a burning smell, smoke and discharge in the room, all power should be cut off immediately to avoid fire.

3. If the fuse is blown, it should be replaced in time, but it cannot be replaced by copper, iron or pure aluminum wire.

4. The room should be equipped with candles, flashlights and other emergency lighting sources, and placed in a fixed position.

5. The aging of the wire is easy to cause power outages, and it should be reported to the relevant departments for replacement as soon as possible.

6. If it is found that the power outage is not caused by indoor reasons, you should contact the property management personnel in time.

The call at the moment of a power failure is called a power trip

The reason for the sudden power failure at home and the immediate call from the sail cover is because the heavy load exceeds the rated load, which is an overload protection trip. Some electrical appliances have grounding phenomena and trip due to leakage protection, and the electrical appliances can be gradually plugged in or turned on.

When a certain electrical appliance is turned on and trips, it is necessary to first check whether there is a suspicion of leakage, or a high-power electrical appliance that has accumulated to the point where the load exceeds the rated load and starts to make trouble. Inspection and analysis 1, check the leakage can turn off or unplug other electrical appliances, and turn on this one separately.
