Abstract

The invention provides a high-voltage cable insulation state on-line detection system based on self-induction energy taking and power supply. The insulation state on-line detection system comprises asignal acquisition unit, a signal conditioning unit, an A/D conversion unit, an energy taking and power supply unit, a central control processing unit, a communication unit, a key unit, a storage unit, a display unit, an alarm unit and a monitoring center. The insulation state on-line detection system obtains electric energy from a tested cable through the energy taking and power supply unit, andjudges the working state of the tested cable by analyzing and calculating the collected signal. The high-voltage cable insulation state on-line detection system based on self-induction energy taking and power supply has the advantages that electric energy needed by the detection system on site is obtained in an on-site self-induction energy taking mode, and the safety and reliability of the detection system are improved.

Description

technical field [0001] The invention belongs to the technical field of electric power detection, and in particular relates to an on-line detection system for the insulation state of high-voltage cables based on self-induction energy harvesting and power supply. Background technique [0002] With the continuous development of my country's economy, people's demand for electric energy is increasing, and the overall electricity consumption of the society is constantly rising. The increase in the overall electricity consumption of the society will lead to an increase in the pressure on the national transmission lines. In cities, due to the increasing shortage of land resources, overhead lines will pose a potential threat to the safety of citizens' electricity use, and messy overhead lines will affect the appearance of the city, so more and more overhead lines are replaced by underground cables. substitute. Cable lines are laid underground, unlike overhead lines, they are easily...
