Description

technical field [0001] The invention belongs to the technical field of electric power inspection, and in particular relates to a high-voltage cable inspection instrument based on electric power safety. Background technique [0002] The cable is one of the most basic structures in the power industry. The cable is used for power transmission. The cable is generally made of one or more mutually insulated conductors and an outer insulating protective layer. The cable is different according to its application scenarios. It also has different classifications, mainly including power cables, control cables, compensation cables, shielded cables, etc. In order to ensure the safe use of cables, it is necessary to check the cables before they are put into use, so as to avoid bad cables being put into use. ACCIDENT. [0003] Today's high-voltage cable inspectors based on electrical safety generally use ultrasonic waves to inspect the inside of the cable. If it detects that there is dama...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that today’s high-voltage cable inspection instruments based on electric safety generally inspect the interior of the cable through ultrasonic waves, and if any damage or abnormality is detected inside the cable, the inspection instrument will give an alarm to complete the inspection. Using ultrasonic testing, if there are some magnetic substances on the outside of the cable, it will affect the detection accuracy and cause inaccurate inspection results. A high-voltage cable inspection instrument based on electric safety is proposed.
