I don't know what power switch you are talking about, but under normal circumstances, the electric switch will not ring, if it rings, there may be a problem with the power switch, you should contact the after-sales service in time to find out the cause and avoid causing greater damage.
-
The power switch is for an hour, and the first time this is a fixed setting, because the system is set in this way, and it is relatively safe. This serves as a warning.
-
This is a normal set of audible alarms.
-
The power switch drops 1 time an hour, and some power switches have this function, right?
-
The power switch rings once an hour, it may be the power switch, and the fault caused by insufficient battery power is, of course, it is best to see if there is any other alarm fault information.
-
The reason for the tripping of the leakage switch is because of the leakage of a certain electrical appliance including the switch, the socket, or the line itself.
-
In this case, you look at the switch should be alarming, you look at the instructions on how to operate this situation, or you can ask the manufacturer directly.
-
There is a prompt sound for the power switch for an hour, maybe it is a reminder set for each hour.
-
It should be that your power supply is aging and the contact is poor. It is recommended to go to the after-sales service to take a look at it, if there is no warranty period on the repair, after the warranty period you can ask what the reason is, to other places for maintenance.
-
The power is turned on for an hour, the first time you look at it, is your power supply just set the alarm at that time?
-
What's going on with this switching power supply for an hour, this is generally uh yes yes yes it can do this one.
-
The first time the power switch is an hour, there should be a problem with the ballast inside, if so, which electrical appliance, you should see if the electrical appliance has a circuit problem.
-
Start in an hour ... How many years ago did your computer go?
It may also be that there is a problem with the motherboard, and it may have been used for too long.
-
Check whether the switch wiring is loose, causing the switch to heat up and trip, and tighten the wiring screws with a well-insulated taper.
-
There are many possibilities for this kind of problem,1It is caused by loose screws of the binding post and poor contact. Tighten it with a screwdriver.
2.It is too much power to use electricity, and now the total configuration of commercial housing is generally 40, and some are replaced with large ampere 63 when they are decorated, or larger, so it causes the home switchboard to be empty and not tripped, and the downstairs is tripped. If this is the case, it is more complicated to solve, and the electricity meter and the downstairs empty opening need to be replaced, or the electricity power will be reduced.
3.The humid air downstairs caused the leakage protection to trip.
-
It is estimated that the wiring of the air switch is loose, or the line connector has loose tape or leakage.
-
Wires can trip if they leak or are short-circuited.
-
If the gate is broken, go change it, or the electricity consumption of your house is too large, so it will be like this, call the electrician to see.
-
You can give it a try and unplug all the electrical appliances at home, and if you still jump, it is a fault with the wiring, and if you don't jump, it is a fault with the electrical appliances.
-
Maybe the wires are tied together, and once in my family, as long as the living room lights are turned on, all the lights are tripped, and it is more troublesome to find an electrician to check the wire.
-
The load is large, the overload is overloaded, the thermal protection is tripped, and the power is changed.
-
The total power is too large, and high-power electrical appliances should not be used at the same time.
-
It should be which socket is in poor contact.
-
If the gate is small or there is leakage, ask an electrician to see.
-
There is a leakage, so check it out thoroughly!
-
You've got some electrical appliances leaking.
-
It's okay to be normal, the buzzer of the air conditioner power supply is ticking, which means that the air conditioner has power supply, normal, don't worry about using it.
-
The air conditioner is just a beep, it's okay,
-
There is no danger, it is just a tone.
-
This is a common problem with switching power supplies.
The "sizzle" sound you hear is emitted by the high-frequency transformer in the transformer, this sound is called "whistling" in electronics, the winding of the electronic transformer will produce a high-frequency magnetic field, if the magnetic ring outside the winding is loose, the magnetic ring will move rapidly under the action of the high-frequency magnetic field, producing a high-frequency chirp. There are two main causes of this noise:
1. The enameled wire of the high-frequency transformer is not completely impregnated, resulting in coil vibration;
2. The silicon steel sheet in the middle of the high-frequency transformer is loose, resulting in vibration;
When I was in college, my first extracurricular production was the power amplifier, which involved a high-frequency transformer, and the "whistling sound" was obvious at that time, and it was unqualified, and a few drops of 502 or rosin were dropped into the high-frequency transformer under the guidance of the teacher, and this problem could be effectively solved in an instant.
After unplugging the mobile phone, the charger output is open, which is equivalent to no load. In order to reduce the loss at no load, the chip will reduce the operating frequency, which can be heard if the frequency is reduced to a frequency range that can be heard by the human ear (such as below 20kHz).
ps: I just took a look, the charger manufacturer has a "whistling" test item in the product factory sampling inspection project.
-
When the oscillation frequency is critical, a whistling sound is emitted. You can fine-tune the starting resistor to make it whine disappear.
-
That's because the frequency of its vibrations is in the hearing range of the human ear, and if the frequency is higher, it will not be heard. Therefore, this power supply itself is problematic, and some components of the circuit board should not be matched, resulting in the output vibration frequency of the IC not meeting the standard, making the switching transformer sizzle sound. Generally, it is sent out by the transformer.
If the frequency is very high, you can't hear it, more than 20000hz. Of course, there are also parasitic clutter, which can also cause the transformer to ring.

When you say tripping, is the leakage protector also called the leakage automatic switch tripping? You can connect one end of a light bulb to the live wire, and gently touch the other end to the water pipe (i.e. the ground), if the same trip occurs, it means that the fire wire and the ground are not well insulated somewhere when you are decorating. How to find the fault, only through the socket one by one to check, some sockets when there is electricity always does not cause tripping, it means that the place is fine, if a socket is easy to cause tripping when there is electricity, it is the place where the wire in the wall has a problem, mainly to check the wire has a joint.
As for sometimes being good and sometimes being bad, it means that the leakage is not serious and unstable. I wish you a happy Chinese New Year!
The above is the answer made in 2-7 23:44.
I just saw a message from you:
Hello, thank you very much. Please ask why it trips every 2-3 days, and it will take 1 to 2 days to use it normally.
As I said above, "As for sometimes being good and sometimes being bad, it means that the leakage is not serious and unstable." "That's it, the temperature, humidity, vibration and other factors in the house will have an impact, as for the length of the interval, it is uncertain, is it true that you say 2 days is exactly 48 hours? Is 3 days exactly 72 hours?
Not necessarily, there is no need to ask about this, there is no timer to start tripping accurately. The key is to find the fault in general and eliminate it. You tell me?
-
Check that there is a problem with that line, and since it appears in 2 or 3 days, it should be a problem on the line that is used more frequently. To 12 sockets (air switch??) Eliminate them one by one.
Also, know which socket or lighting circuit you are using when jumping turns, so it will be easier to find the problem.
-
During the renovation, the line in the wall was injured, the electricity leaked, and the protection tripped.
-
This should be the sound of the air conditioner powering on, and a beep indicates that the air conditioner is powered on normally; There is no danger.
-
The sound of the power drop just turned on means that it is in standby mode, which means that the power supply part is fine.
-
Your "main power switch" is a leakage current protector.
The button above is actually: the experiment button.
It allows you to press once a month, which is to let you test whether this leakage protector still has the effect of automatic protection action in the case of leakage current, overvoltage, overcurrent and overload!
The protection action is: when the current passing through the leakage current protector is short-circuited, over-voltage, overload, and over-current, it will automatically trip and disconnect the open circuit!
-
It's for testing. The test button of the leakage protector to test whether the leakage protection function of the leakage protector is normal.
-
It's for testing. Test button for leakage protector.
-
It is estimated that it is a circuit button to prevent overvoltage protection, but now it can be solved directly with an empty opening.
-
There are two possibilities: one is that the quality of your switch is not good, and you do not use silver alloy contacts, and the arc is relatively large at the moment of contact, resulting in a loud sound; The second is that the switch is aging and the contact is poor, and the switch will not last long in this case. It is recommended that you find a master electrician to help you check the repair.
-
The socket is reconnected, it may be that the distance between the two phases is too small, or there are several copper wires in multiple strands that are not compacted, and there is insulation breakdown at the moment of closing.
Rats are fast, how nice it would be for people to be like that.
The main purpose of early morning exercise is to move your muscles and bones, breathe fresh air, make you feel energetic all morning, I don't know what you exercise for an hour, it is recommended that you stretch, jog, don't do too intense exercise, and be sure to eat breakfast. According to Chinese health care, spring and autumn are suitable for going to bed early and getting up early, in summer, it is suitable for going to bed late and early, and in winter, it is best to go to bed late and get up late, day by day. Waking up early in the winter to exercise is not a good thing in that regard. >>>More
