Description
Technical Field
The invention relates to the technical field of cable monitoring, in particular to a cable sheath circulating current collecting device based on CT electricity taking.
Background
When current flows through a high-voltage cable in normal operation, induced voltage is generated on a cable sheath, so that one end of the cable sheath is grounded generally for the safety of personnel. Therefore, the cable sheath forms a passage with the ground, cable sheath circulation is generated, and the operation condition of the cable can be known by collecting the cable sheath circulation. CT power taking is also called induction power taking, and electric energy is generated by inducing the cable sheath circulation on the cable. The cable sheath circulating current collecting device used at present works by applying an external power supply, wind energy and solar energy, although the wind energy and the solar energy can be environment-friendly, the wind energy and the solar energy are greatly influenced by the surrounding environment and cannot meet the requirement, and the CT power taking utilizes the cable sheath circulating current induction electric energy generated by a high-voltage cable, so that more energy conservation, high efficiency and stability can be realized. The principle of CT electricity taking is the same as that of cable sheath circulation collection, wherein the CT electricity taking is used for converting sensed current into stably output voltage, and the cable sheath circulation collection is used for converting and recording the sensed current, transmitting the converted current to a computer and analyzing the current. At present, the cable is stolen occasionally, and the cable needs to be monitored in order to ensure the normal operation of the cable.
