Description

Technical Field

[0001] The utility model relates to the technical field of power lines, in particular to a power line with a cutting function. Background Art

[0002] Power cords are wires that transmit current. Usually, the current is transmitted point-to-point. Power cords can be divided into AC power cords and DC power cords according to their uses. Usually, AC power cords are wires that transmit higher voltage alternating current. Due to the higher voltage, this type of wire needs to obtain unified standards and safety certification before it can be officially produced.

[0003] The Chinese utility model application number CN202122710268.2 discloses a power cord with a temperature-controlled power-off indication function. Once the temperature-controlled switch is disconnected, the user will be prompted to handle it. A power cord with a temperature-controlled power-off indication function includes a temperature-controlled switch and a power cord body. The temperature-controlled switch is connected in series with the power cord body. The power cord body includes a metal wire and an outer protective skin that wraps the metal wire. The partial outer protective skin of the power cord body is made of a transparent material. The inner wall of the outer protective skin of the transparent material is provided with a reversible thermochromic material layer. The reversible thermochromic material layer senses the temperature of the metal wire to change color. Once the temperature-controlled switch is disconnected, the buzzer linked to the temperature-controlled switch will alarm the user and prompt the user to handle it. However, there are still some power outages in the use of the device: the device senses the temperature of the metal wire through the reversible thermochromic material layer to remind the staff of the abnormality of the power cord, but when the power cord is working in the outside world, the sun's irradiation easily causes the reversible thermochromic material layer to fade and fail, thereby causing the reminder effect for the staff to deteriorate.
