Not long ago, my friend said that there was a problem with his circuit. Let me see what the cause was. After measuring with an electric pen, it was found that the neutral line was charged. We know that under normal circumstances, the neutral line is not live, so my friend What’s wrong with the electricity at home?
Usually the neutral line is charged for the following reasons:
- When the home was connected to the power grid, some people grounded the neutral wire to protect the electrical appliances; 2. The three-phase load was not balanced, resulting in unstable neutral potential, so there was voltage;
- Connect the neutral wire Put together.
Analyzed the situation of a friend’s house. Generally speaking, the neutral wire is basically a poor grounding. The more common reason is that the neutral wire is not connected well or broken. There are also some other rare reasons that open the socket of a friend’s house. It was later confirmed that the circuit problem at my friend’s house was caused by the break of the neutral wire.
But how can we solve the problem of zero line electrification? In fact, it is not difficult.
- Based on the zero line, expand and strengthen the inspection of the connection method and effect of the connecting line,
- All wires of the live wire will pass through the neutral wire, so the area of the neutral wire must be large enough, or a neutral wire can be connected from the main switch box.
- Eliminate wire breakage caused by external force.
- If the neutral wire flickers when turning on the light, you should first check whether there is a short circuit at the lamp head and the quality of the light switch; if the neutral wire on all parts of diangon.com is live, you need to check the total The neutral line of the switch.
Based on the above points, no matter what is caused by the neutral line, it will lead to unsafe electricity consumption. Therefore, we must pay great attention to it. If it is not handled properly, it will bring unimaginable harm to life. Therefore, when installing wiring, Be sure to buy good quality and guaranteed regular wires. Secondly, look for a skilled and responsible electrician. Be sure not to sloppy when wiring and pay attention to the details. After all, the responsibility for safety is heavy, and the safe use of electricity is important.
