Как к использовать а мультиметр к проверить если холодильник есть утечка или короткое замыкание замыкание
1. There is a phenomenon of "soft breakdown" in the "socket" circuit in your home. The method of judgment is to use a 500V tramegger (megohmmeter) to check the insulation between the "zero line" and the "live line" after the power outage, and the minimum insulation resistance should not be less than 0.5 megohms,
2. There is a slight leakage phenomenon in the "socket" circuit in your home. The inspection method is to remove the "zero line" and "live line" of the "socket" circuit in your home, and then connect it to any other switch with the same capacity in the distribution box. If this switch no longer trips after closing, then there is a slight leakage phenomenon in the "socket" circuit in your home. If this switch still trips after closing, it means there is a "soft breakdown" phenomenon in the "socket" circuit in your home.
3. There is a problem with the leakage protection switch of the "socket" circuit in your home. You can try replacing it.
Наконец, I give you a piece of advice; Do not listen to those who do not understand electricity and blindly increase the switch capacity, else there is danger. Is there an electrical appliance with a high load?
If not, then something must have a short circuit It's a problem with the wiring. There may be a short circuit somewhere in your home. Please have an electrician check it at home. That's because there's a short circuit somewhere!!! Check carefully if the switch is broken, short circuited, or leaking. I don't know if you have changed the circuit during renovation. If the cable is laid without a protective tube, this problem may occur. There are two possibilities for this problem: overload of the load; There is a short circuit in the circuit Personally, the biggest possibility is that there is a problem with the leakage switch, as you mentioned that the main switch also jumps. The reason for the main switch to jump is due to excessive current. If it is an electrical leakage, it will not jump for a few minutes. It should be in an instant: between 20ms and 40ms. I replaced the leakage switch and gave it a try. It may be due to poor internal insulation^_^
The key fault area is in the kitchen and bathroom. Equipment: washing machine, refrigerator, air conditioning, water pump. It is very likely that the wire was skinned, grounded, or short-circuited by mice and cockroaches. Then you need to carefully check and seek help from the power supply bureau to replace a thicker fuse if necessary
