Leakage protector tripping is a common occurrence in the home. Many people do not know the cause of the leakage protector tripping, so they all want to understand. Leakage protectors are divided into normal trips and abnormal trips. Normal trips can effectively prevent a series of problems caused by leakage. Then let Xiaobian take everyone to look at the relevant introductions about the exciting content of the leakage protector tripping .
Leakage protector trip cause
The function of the leakage protector is to effectively control the disconnection of the home circuit and the occurrence of electric leakage and electrical accidents. Therefore, the reasons for tripping can be divided into two types, one is normal tripping and the other is abnormal tripping.
Normal trip
If the rated leakage current is 30MA, the leakage current will be more than 25MA in the load, and the leakage switch will trip. Since the current of the 25MA is safe to flow through the human body, there is no electric shock to death; the same is true for the line or electrical equipment, and the operation of the electrical equipment does not cause an abnormal phenomenon.
Abnormal trip
This kind of trip is caused by the unqualified quality of the leakage switch itself, which can be divided into two categories and sometimes no reason to trip. In the case that the leakage switch is connected to the power supply without being connected to the load, if it is not connected, it is definitely the quality problem of the leakage switch. Do not repair it yourself, because it must be tested after technical performance before being put into use. No test equipment is used. It is not safe to use after testing.
The second type is occasional tripping, especially when it is tripped in the middle of the night or when there is no one in the home. This trip indicates that the leakage resistance of the leakage switch is poor. The leakage switch with abnormal trip should be removed and replaced with a good leakage switch.
1. The leakage protector is installed at the outlet of the branch line, and the leakage protection socket is installed at each end of the electrical appliance, which belongs to the end installation. Installation and maintenance is more convenient.
2. Difference in leakage: Leakage protector When the line is leaking, because it is installed at the branch line exit, the terminal failure will cause the entire branch to be powered off, and the leakage protection socket, when the electrical circuit or line in the branch leaks, Only the single-branch line is not energized, and the appliance cannot work.
3. Wiring protection difference: The leakage protector only has the fire line protection, and the leakage protection socket has the fire line and the zero line protection.
4. Leakage current and leakage trip time difference: Leakage protector: Iâ–³n=30mA, action time 0.1S, leakage protection socket: Iâ–³n=6mA, action time 0.025S. Leakage protection socket, rated residual leakage current is smaller, safer, less damage to the human body, quick tripping. Protect people's lives and property.
5. Poor installation: If the leakage protector is not firmly connected during installation, the length of time will often cause the terminal to heat up and oxidize, causing the wire insulation to be burnt, accompanied by ignition and rubber and plastic burning. The odor caused the line undervoltage to trip the leakage protector.
6. The leakage protector itself has a problem: when purchasing the leakage protector, the user should try to buy it from a reputable manufacturer or store. Don't buy a “three no†leakage protector from some self-employed households at a time, which is often worth the loss. .
7. Leakage protector does not match the load: With the increasing popularity of household appliances, the load current of many households has far exceeded the rated current of the leakage protector on the line, causing the leakage protector to trip. This kind of situation generally occurs in the use of high-power appliances such as air conditioners and electric kettles. Generally, as long as a matching leakage protector is replaced, the problem can be solved.
8. Load or line leakage, short circuit: If the load leakage or short circuit of the appliance is such that the leakage protector trips, as long as the faulty appliance plug is unplugged, the power can be re-powered; if it is a line leakage or short circuit, relatively compare Tricky, you can solve some simple faults first, so that some lines temporarily resume power transmission.
The specific method is as follows: when the leakage protector trips, first disconnect each branch, and then send the leakage protector. When the leakage protector is tripped when a certain branch is sent, it can be concluded that the branch is faulty. As long as the branch is disconnected, the other branches can be restored. At this point, if the socket or fixture in a room is found to be out of power, the fault is often in this zone.
How about, I read the above introduction to the leakage protector tripping, and I have learned a lot about the leakage protector tripping. I hope that you can learn more about home improvement knowledge through this article, and you will be able to create a more perfect home environment. Thank you for reading this article and your support and love for Xiaobian. If you want to get more information about home improvement, please continue to pay attention to the decoration home network.
