Common trip reason and treatment method of electric leakage protector
1. Poor installation
If the leakage protector in the installation of the terminal column is not firmly connected, for a long time, often will lead to the terminal heating, oxidation, so that the wire insulation layer is burned, and accompanied by fire and rubber, plastic combustion smell, resulting in the line underpressure makes the leakage protector trip.
2. There are problems with the leakage protector itself
When the user is buying leakage protection device, should be as far as possible to the good reputation fixed-point manufacturer or shop to buy, do not figure temporarily cheap to some self-employed to buy “three no” leakage protection device, so often the gain outweighs the loss.
3. The leakage protection device does not match with the load
With the continuous popularity of household appliances, the load current of many homes has far exceeded the rated current of the leakage protector on the line, causing the leakage protector to trip. This kind of situation generally happens more in the use of air conditioning, electric kettle and other high-power home appliances, generally as long as a matching leakage protector, the problem can be solved.
4. Load or line leakage, short circuit
If it is home appliances and other load leakage or short circuit and leakage protection device trip, as long as the fault of the home power plug, you can re-power; if it is a circuit leakage or short circuit, relatively difficult, can first solve some simple faults, let some lines temporarily restore power.
The specific practices are:
When the leakage protector trip, the first disconnected from the branch, and then the leakage protector, when sent to a branch of the leakage protection device is tripping, it can be concluded that the branch has a fault. As long as this branch is disconnected, the other branches can resume electricity. At this point, if the socket or lamp in a room is found dead, the fault is often in this area.
5. The power supply incoming line voltage is too high
This situation is rare, but very dangerous, generally occurs in the three-phase four-line system of power supply of residential buildings (now the residential buildings are generally so power supply). Due to the three-phase imbalance or mice and other small animals disturbance, the power supply total zero circuit break voltage drift, phase voltage can be changed from 220V to 380V, will make the leakage protector trip.
To discern this kind of fault, one is to test whether the incoming line is live;
The second is to see if the neighbors also have a trip phenomenon, if there is, most of them belong to this fault;
Three is to use the multimeter to measure the incoming line voltage.
At this time, please do not force to close the leakage protector switch, otherwise easy to cause home appliances burned out, serious will also lead to fire and other adverse consequences. In addition, the incoming line suffered from lightning will also cause overvoltage caused by leakage protector trip.
In short, once the household leakage protector trip, the inspection should follow the principle of the first simple after complex. First of all, check whether the installation is good, and then check whether the power supply incoming line voltage is high (see the neighbors) and the leakage protector itself has a problem (discharge the outgoing power transmission), and then it is to see whether the leakage protector can bear the load of home appliances, and finally check whether the load, line leakage or short circuit.
If you really can not find out the reason, do not blindly move, should ask the professional personnel to check. Otherwise, the line of chaos is not conducive to troubleshooting.
