The power in my bedroom suddenly went out, and I found someone to open the main gate, and then the p

There is a leakage or short circuit, such as an electric kettle connected to electricity, or someone is electrified, I hope it can help you.

There was some high-power electrical appliance in the dormitory, tripped.

There are many reasons for this, but the most likely circuit is leakage and wiring.

Wiring or overloading, these are the only two reasons.

The reason why the dormitory has lost power but has not tripped may be that part of the fuse has melted, and when you use the electrical appliances, the normal load can no longer bear it, so the power goes out.

The safe operation of the traction power supply system that supplies power to the electric locomotive should be ensured. In the event of an accident, the relay protection device installed in the traction substation (opening and closing station, partition pavilion) will be activated by the short-circuit current generated by the accident, and the circuit breaker that supplies power to the accident point will be automatically disconnected, so as to reduce the scope of the accident and ensure the safe operation of other equipment and the normal power supply to the non-accident line. This action of automatically disconnecting the circuit breaker due to an accident is customarily called "tripping".

Trip conceptThe main task of the traction substation (opening and closing station, partition pavilion) is to supply power to the catenary. In addition to the equipment failure of the traction substation (opening and closing station, partition pavilion) itself (the proportion of this situation is very small), the short-circuit current that causes the "tripping" mainly comes from the catenary.

It may be a power outage or a line problem, don't do it yourself, just find the dormitory manager and let them help solve it.

A "dormitory" is a house where you can live in a dormitory, including a dormitory, a bathroom, a bathroom, a balcony, etc. The number of people living in the dormitory varies, and there are single rooms, double rooms, and multi-person rooms. Different schools have dormitories of different specifications, and the dormitories support different equipment and electrical requirements.

In order to strengthen standardized management and do a good job in the building of the two civilizations, the special management system is as follows:

1. It is forbidden to smoke or litter cigarette butts in bed.

2. It is not allowed to pull and erect wires indiscriminately, and the bulb is limited to less than 60W.

3. It is forbidden to use electric frying pans, electric stoves, rice cookers and open flames for cooking.

Fourth, it is forbidden to spit or urinate or urinate.

5. It is not allowed to dump dirty water and all kinds of sundries, indoor living utensils are placed neatly, outdoor sanitation environment is done, indoor and outdoor disinfection is concentrated once a week, and the sanitation work is inspected by a special person.

The first thing that should be thought of should be where the circuit is broken or the contact is poor, because the air switch should be tripped in the normal configuration of the short circuit, and the air switch cannot all be broken together, only when the circuit is disconnected can there be no trip and no power, the most likely is the line problem from outside the house to the distribution box in the house, such as mice or other things touching the wire joints resulting in poor contact, and the power supply is unstable in the case of poor contact, and the load is slightly larger so that the weak connection is directly burned out.

It is mainly necessary to measure along the main line to determine the location of the fault, so it is better to ask an electrician to check it for safety.

Check with an electrician, the possibility is that the connector is loose and heated.

1. The reason for the sudden power outage: there is a power outage. The circuit is short-circuited and withered.

A short circuit can cause excessive current, causing the fuse to blow or the circuit breaker to trip. The circuit is overloaded. The new high-power electrical appliances are added, and the fuse and circuit breaker are not replaced in time, resulting in overload of the circuit, excessive electrical power and excessive current, which makes the fuse blown or the circuit breaker tripped.

There is a problem with the socket. This problem can lead to the temporary activation of the overcurrent protection device in the distribution box. There is a problem with the fan, which is extremely unlikely.

Overvoltage protection caused by sudden excessive fan current.

2. A sudden power outage may destroy electrical appliances and directly affect people's normal lives. A power outage, i.e., the cessation of power transmission, makes it impossible for electrical appliances to obtain external power. This can include man-made power outages (e.g

Maintenance of lines, off-peak power consumption, power rationing, arrears of electricity bills, etc.), protection against power outages (such as: lightning protection, prevention of electrical overload, etc.), accidental power outages (such as: man-made sabotage, bad weather, circuit short circuit, accidental disconnection of the road, etc.).

3. Emergency measures: In case of power failure, lighting tools such as flashlights should be used to first check whether the internal power distribution switch and leakage protector are not jumped. If there is a burning smell, smoke and discharge in the room, all power should be cut off immediately to avoid fire.

The fuse is blown and should be replaced in time, but it cannot be replaced by copper, iron and aluminum wires. The room should be equipped with candles, flashlights and other emergency lighting sources, and placed in a fixed location. Aging wires are easy to cause power outages, and should be reported to the relevant departments for replacement as soon as possible.

4. If there is a planned power outage, manufacturers and citizens are prepared, and backup generators, flashlights, etc. can be arranged. However, unplanned power outages can easily lead to fatal consequences, such as hospital operating theatres, airport customs and security screening systems, computer servers, lifts, factory assembly lines, etc. After a power outage, the sudden resumption of power transmission will cause accidents and damage electrical appliances, which must be prevented.

After the power outage, all production and living economies were paralyzed in an instant, with insufficient lighting and no electricity (**, computers, etc.) communication.

The whole building is out of power in my house, but what happened if it didn't trip?

Dear, I'm glad to answer for you: first observe whether there is electricity in the house next door or neighbors, on the street and other public areas. If there is none, there is a problem with the power supply line.

If only your home has a power outage, it means that there is a problem with the line at home, and the main gate should trip by itself. Look at the leakage of the home Sakura switch judgment section has tripped, if not, it means that there is no problem with the circuit and electrical appliances at home. At this time, we use an electric pen to measure the circuit on the light to see if it is still charged, and after confirming that there is no electricity, we will knock down the switch of the switch switch and completely cut off the power supply.

Precautions: When the power supply is restored and the nearby electricity consumption is normal, turn on the leakage switch at home. This is to protect the electrical appliances in the home from the sudden increase in current due to the power supply restoration, which is easy to damage the electrical appliances.

Most trips are short circuits. The air switch is generally one at home, and there is also one in the unit. You just go find the one in the unit.

1. Most of the trips are short circuits. The air switch is generally one at home, and there is also one in the unit. You just go find the one in the unit.

But you have to find the place where the circuit in your home is short-circuited. Generally, the air switch in the home is split. You first turn off the short-circuit and push the others up, and the room without the light is the short-circuit place, and then you find the short-circuit place of the line, fix it, and finally push the switch on it.

2. Your home may be a leakage switch, if it is, you should press the square button first and then close.

3. There is a small button on the leakage switch to see if it can be pushed up, if it still doesn't work, it may be a short circuit or leakage somewhere.

There is also a general gate, that is, there is a gate jump in front of the main gate!

The reason why the power in the university dormitory will be cut off at night is that these reasons are very important in its loose training:

1) Help students sleep regularly.

Although I went to university, we are still students, and we still have to focus on studying, and if we don't rest well at night, it will really affect the mental state of the next day, and the efficiency in class is not high.

The school disconnects the network and power to everyone at night, which is also to ensure everyone's sleep quality, and also help students develop a good habit of regular sleep, which is of great help to physical health and learning.

2) Avoid conflicts in the dormitory.
