Short circuit of wires is one of the main causes of household fires, so we must pay attention to the problem of short circuit of wires when using electricity at home. So next, we will invite teachers from Zhangjiakou Wenhua Electric Power Vocational School to explain the causes of wire short circuits and the methods to prevent wire short circuits, hoping to help everyone.
The reasons for short circuits in electrical wires
Short circuit refers to the direct connection of the two ends of a wire without the use of electrical appliances, which can cause the wire to heat up, explode slightly, and even ignite. There are many reasons for short circuits in daily life, such as frequent entanglement of wires and aging of insulation glue. There are usually two thin wires in a wire, one is a neutral wire and the other is a live wire. Each thin wire is composed of many copper wires, and some wires used in electrical appliances are often wrapped or squeezed. Over time, this can cause the internal copper wires to become chaotic, even breaking through insulation paint and touching the copper wires inside a thin wire. The current is connected to another wire before it is used, forming a circuit and causing a short circuit.
Methods for preventing short circuits in electrical wires
1. Choose the correct electrical circuit. Do not use overly thin or inferior wires for the sake of small gains. When selecting wires, attention should be paid to checking whether they are qualified products.
2. Safe use of electrical circuits. The installed electrical circuit should not be pulled, connected, or equipped with electrical devices randomly to increase the electrical load of the entire circuit, otherwise it is easy to cause accidents.
3. Use safe electrical switches. Knife switch can generate electric sparks during switching, which can easily create danger. The use of an air switch can provide power outage protection. When using a fuse, it is important to choose a suitable fuse to avoid malfunctions. When the current increases, it can be cut off in a timely manner.
4. Regularly inspect electrical circuits. We should insist on regular inspections and hire specialized electricians to help inspect electrical circuits at regular intervals. If insulation layer damage is found, it should be repaired in a timely manner.
5. Install the wiring according to the requirements. The installation of electrical circuits must strictly follow the electrical installation regulations, and specialized electricians must be hired to lay the circuits. Electricians must hold their work permit.
After reading the above content, do you also have a certain understanding of wire short circuits? If you want to learn more about electricity, we recommend everyone to register and study at Zhangjiakou Wenhua Electric Power Vocational School. Zhangjiakou Wenhua Electric Power Vocational School is looking forward to your arrival.
