Problems solved by technology

Because the cable needs to be touched manually when clamping the cable, personal safety cannot be effectively guaranteed when the cable is running live. In addition, various complicated reasons such as the installation position of the cable make it impossible to monitor the cable grounding current signal quickly and safely. Therefore, daily monitoring Cable monitoring needs to bear a lot of workload and safety risks, which greatly reduces the reliable monitoring of safe and stable operation of cables

Abstract

The invention discloses a high-voltage power transmission cable earth current automatic detection device. The device comprises a sampler (13) and a receiver (16). The sampler (13) comprises an upper shell (2), a middle shell (3) and a lower shell (1). A PCB panel (4) is arranged on the upper shell (2). A first induction coil (10) is arranged in a first chamber (9) of the left part (21) of the middle shell. A second induction coil (12) is arranged in a second chamber (11) of the right part (22) of the middle shell. The first induction coil (10) and the second induction coil (12) are connected with a control circuit of the PCB panel (4). A supporting bar (7) is arranged between two bulges (6) on the left part (21) of the middle shell and a supporting bar (7) is arranged between two bulges (6) on the right part (22) of the middle shell. The two supporting bars (7) are connected by a spring (8). The device is simple in structure and convenient for installation, has strong environmental endurance, is low in safe risk, and can do monitoring in real time.

Description

Technical field: [0001] The invention relates to the field of high-voltage cable detection, in particular to an automatic detection device for grounding current of high-voltage transmission cables. Background technique: [0002] Ground current is an important parameter in cable detection. At present, ground current detection mainly uses clamp meters to manually clamp the caliper on the cable to collect and observe current signals. Because the cable needs to be touched manually when clamping the cable, personal safety cannot be effectively guaranteed when the cable is running live. In addition, various complicated reasons such as the installation position of the cable make it impossible to monitor the cable grounding current signal quickly and safely. Therefore, daily monitoring Cable monitoring needs to bear a lot of workload and safety risks, which greatly reduces the reliable monitoring of the safe and stable operation of cables. Invention content: [0003] The purpose ...
