Overload protection is one of the important functions of cigarette plug extension cable. When the current exceeds the rated current of the extension cord, the overload protection device will start. For example, when the power of the device we connect is too large and exceeds the range that the extension cord can withstand, it will automatically cut off the circuit to prevent the wire from heating up or even catching fire due to excessive current.
Short circuit protection is also indispensable. Short circuit refers to the formation of a loop in the circuit without passing through the load. Once a short circuit occurs, a huge current will be generated instantly. The short circuit protection mechanism of the extension cord can quickly detect the short circuit and cut off the circuit in time to avoid sparks and dangers caused by the short circuit.
In order to ensure safety in use, first of all, you must choose an extension cord of qualified quality. High-quality extension cords have strict standards in materials and processes, which can effectively prevent overload and short circuit. For example, some brands of extension cords use high-temperature resistant and flame-retardant materials, which greatly reduces safety risks.
When using an extension cord, pay attention to the correct connection method. Make sure that the plug and the socket are tightly connected to avoid looseness. At the same time, do not place heavy objects on the extension cord to prevent squeezing and damage to the wires.
It is also very important to check the condition of the extension cord regularly. Check for signs of wear and aging, and replace them in time if any problems are found. Especially after long-term use, pay more attention to checking its performance.
In addition, it is also critical to use the extension cord reasonably. Do not connect multiple high-power devices to the same extension cord at the same time to avoid exceeding the carrying capacity of the extension cord.
In short, the cigarette plug extension cable has functions such as overload protection and short-circuit protection. By choosing high-quality products, using them correctly and checking them regularly, it can effectively ensure the safety of use. We must always pay attention to the safety of extension cords to ensure their stable and reliable operation.
