Description

technical field [0001] The invention relates to the technical field of power line fault detection, in particular to a low-voltage power line fault detection and positioning system and a fault detection method. Background technique [0002] Low-voltage power lines, also known as low-voltage cables, are conductors covered with insulating layers, protective layers, shielding layers, etc. used to transmit power or signal currents and signal voltages. According to the voltage, it can be divided into high-voltage cables and low-voltage cables. Compared with low-voltage overhead lines and low-voltage overhead insulated lines, although low-voltage cable lines are more expensive and difficult to lay and maintain, they are reliable in operation, do not erect poles, do not occupy the ground, are not unsightly, and are less affected by the outside world. characteristics, and are widely used in low-voltage power distribution systems; however, low-voltage power lines are easily affected ...

Problems solved by technology

Compared with low-voltage overhead lines and low-voltage overhead insulated lines, although low-voltage cable lines are more expensive and difficult to lay and maintain, they are reliable in operation, do not erect poles, do not occupy the ground, are not unsightly, and are less affected by the outside world. characteristics, and are widely used in low-voltage power distribution systems; however, low-voltage power lines are easily affected by voltage, such as excessive voltage, low voltage, or grounding of low-pressure lines will cause power lines to be faulty, thereby affecting work efficiency; therefore, the invention It is particularly important to develop a low-voltage power line fault detection and location system and fault detection method

[0003] Existing low-voltage power line fault detection is usually carried out by manual detection. This method is inefficient and cannot accurately locate the faulty low-voltage power line. The detection accuracy is not high. When the faulty low-voltage power line cannot be accurately detected, it may take Replacement or interception of the entire section results in waste of low-voltage power lines and high cost of use; for this reason, we propose a low-voltage power line fault detection and positioning system and fault detection method
