Description

TECHNICAL FIELD

[0001] The utility model relates to line protection technical field especially relates to a line protection device. BACKGROUND

[0002] When too many electrical equipment are accessed in the line or the voltage suddenly rises, the line will bear excessive current and voltage, which can easily cause problems such as line overheating and accelerated insulation aging. The line protection device can monitor the current and voltage of the line in real time, automatically cut off the power supply when overload or overvoltage occurs, prevent the line from being damaged due to overheating, and prolong the service life of the line.

[0003] Traditional line protection devices usually use fixed-size clamping components. When clamping lines of different thicknesses is needed, the fixed-size clamping components cannot closely fit the surface of the line, which can cause the line to loosen at the clamping part. During the operation of the equipment, the line may shake due to factors such as vibration and external force pulling, which can further cause poor contact, affect the stability of power transmission or signal transmission, and even cause the line to fall off, resulting in equipment failure or safety accidents. Traditional line protection devices are mostly installed independently, and each device is a relatively independent individual, lacking effective connection mechanisms between them. In complex electrical systems, multiple line protection devices are often needed to protect different lines or lines in different areas. Due to the inability to connect between devices, the overall line protection system lacks overallity and coordination. Traditional line protection devices lack unified standardized connection interfaces, and devices produced by different manufacturers differ in size, shape, and connection method, making it difficult to achieve interchangeability and compatibility.
