Embodiment

[0021] Such as figure 1 , 2 As shown, a submarine cable pressure monitoring system of the present invention includes a protective layer 2 arranged on the outside of the cable body 1, there is a gap between the cable body 1 and the protective layer 2, and the protective layer 2 passes through the isolation plate 3 every 1 km For protective partitioning, one end of the isolation plate 3 is connected to the inner wall of the protective layer 2, and the other end is connected to the outer wall of the cable body 1. Each partitioned protective layer 2 is provided with different alarm modules 21 and detection modules 22, and the control center receives the alarm. The signals sent by the module 21 and the detection module 22 are used to monitor the operation of the cable. The various detection modules and alarm modules installed in the gap between the cable body and the protective layer can detect the cable condition in time, and send the detected data to the control center in real t...

Abstract

The invention discloses a submarine cable pressure monitoring system; a protection layer is arranged outside the cable body; a gap is formed between the cable body and the protection layer; the protection layer is protected and isolated by isolation plates at an interval of 1km; one end of the isolation plate is connected with the protection layer inner wall, and the other end is connected with the cable body outer wall; different alarm modules and detection modules are arranged in the protection layer of each section; the control center receives signals sent by the alarm modules and the detection modules, thus monitoring the cable operation conditions. Various detection modules and alarm modules are arranged in the gap between the cable body and the protection layer, thus timely detectingthe cable conditions, sending the detection data to the control center in real time, and allowing control center work personnel to know the work conditions of each section cables. The protection isolation can be realized through the isolation plates arranged in the protection layer, thus clearly determining the problems of a specific section of the protection layer.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a submarine cable pressure monitoring system. Background technique [0002] The development of offshore energy such as offshore wind power has promoted the formation of offshore transmission networks, and high-voltage submarine power cables have increasingly broad application space, mainly including offshore wind power transmission, power supply for offshore oil and gas platforms, island networking, and coastal country networking. As the most important equipment in the offshore transmission network, the safe operation of submarine cables is very important to the power system. [0003] The quality of cable insulation is a key factor affecting the safe and reliable operation of cables. In the past, the widely used preventive measure was to use periodic power outages for detection, which belonged to offline detection. This preventive detection of insulation is obviously unreasonable: first, ...
