Question:

Air conditioner outdoor unit copper leakage 25

Is it possible that as long as the inverter is not grounded, it will leak? Now there is no ground wire, leakage is not a problem on behalf of the machine, or ungrounded, it must leak? Holding the outdoor machine copper pipe, obviously numb feeling. The pen is also bright. I don't know how many V

Answer:

Household appliances should generally be protected earthing, especially with electrical machines, the coil will cause very high induction voltage,.
Check whether the air conditioning ground, the inverter must be grounded, otherwise there will be induction, such as grounding after the outdoor machine and copper tube, there is no induction on the line. Also check whether the air conditioning power switch is leakage switch, and then check the power line, circuit board whether leakage. (there are inverter appliances, I have tried not to ground, the results of the "ma hand" phenomenon, the electricity test written also has electricity, and then multimeter measurement, the voltage is still high! )AskHas the grounding line gone? Is there any leakage of copper wire in the copper pipe? Is there a reason why the machine is defective?Chasing the answerAfter grounding, if the power supply of the circuit board is not leakage, it is OK, so it is also necessary to check the power line, circuit board, starting capacitor, and whether the compressed motor is leakage or not.
[leakage analysis of copper pipe in outdoor unit of air conditioner]1, is not it, as long as the inverter is not grounded, will leak, and now there is no ground wire, leakage is not representative of the machine has a problem, or not the ground must leak, holding the outdoor machine, copper pipe, obviously numb feeling. The pen is also bright. I don't know how many VRelevant explanation: it is this copper tube to touch the hand to have electricity (not often, sometimes, sometimes), and after the hand touches the electricity, very hemp, immediately shrinks back.2, first of all, this leakage should be the switching power supply and the power input ripple capacitor, the voltage may have a one hundred or two hundred volts, but because the current is small, so it does not matter! In fact, many home appliances will also be leakage, such as desktop computer like air conditioning, so no problem, but the best to pick up the ground, in addition to really prevent leakage when the outside power to people but also can protect the electronic components are not static bad motherboard guarantee life, grounding is to prevent leakage of it let the air switch with leakage switch tripping to ensure personal safety.3, copper tube and so on will work as a result of inverter induction electricity, when there is no ground wire will feel. Frequency converter work will certainly produce induction, people feel there will feel. Induction is not electric leakage, as for the machine is not leakage, and now can not be determined, need on-site inspection. Check whether the air conditioning ground, the inverter must be grounded, otherwise there will be induction, such as grounding after the outdoor machine and copper tube, there is no induction on the line. Also check whether the air conditioning power switch is leakage switch, and then check the power line, circuit board whether leakage
In accordance with the state's provisions on the safe use of electricity, all household appliances need reliable grounding.When the frequency conversion air conditioning works, the air conditioner shell, the copper tube and so on will have the induction electricity because of the frequency converter work, when does not have the ground wire, the human body can have the feeling.Frequency converter work will certainly produce induction, people feel there will feel.Induction is not electrical leakage, as for your machine is not leakage, and now can not be determined, need on-site inspection.AskHow will I know if the machine is in question when they come to check it tomorrow? Afraid they do not say, afraid of trouble, do not want to change for me (just bought), just give me a ground wireChasing the answerThe ground wire is not random, you live, if it is in recent years, new buildings, should have the ground wire in line with the requirements.It is very simple to check whether the machine is leak or not. Use a shake meter to measure the resistance to the ground.
First of all, this leakage should be the power supply of the switching power supply and the input ripple capacitor! The voltage is likely to be one hundred or two hundred volts!! But because the current is small, it doesn't matter! In fact, many appliances will leak! Desktop computers, for example, do! So your air conditioner is ok! But you'd better take the ground wire, in addition to preventing leakage of electricity when the real time, the electricity to people, but also to protect the motherboard's electronic parts are not damaged by static electricity to ensure longevity!Right! Because there is no grounding, there is static electricity on the copper tube! This electricity is harmless to the human body! We are grounded in order to prevent leakage of real time, so that air switches and leakage switches are tripping, to ensure personal safety. You have no problem with the air conditioner.AskIf the ground wire is connected, or the leakage will occur, is that the problem of air conditioning?Chasing the answerThere's no electricity on the ground wire! If the leakage, then the leakage switch on the trip! No tripping, no leakage!
