Intelligent cold shrinkage temperature measurement positioning cable joint

Abstract

The invention discloses an intelligent cold shrinkage temperature measurement positioning cable joint. Through directly embedding the stable sensor in the cable core, the cable joint performs stable detection and positioning cooperating with an identification code. The cable joint is characterized by comprising an outer protective layer, a net cover, a shielding cover, a connector body, a temperature sensor, a crimping pipe, an identification sticker and a sealing structure. The outer protective layer is composed of an outer waterproof layer and an armor tape, a rope core is arranged in the outer insulating layer, the outer protective layer shrinks after the rope core is pulled, the net cover is a copper net cover, the temperature sensor is a wireless sensor and can form data feedback withthe data server, and the identification sticker can emit a high-frequency signal.

Description

technical field [0001] The invention relates to an intelligent cold-shrinkage temperature measurement and positioning cable joint, relates to a joint product used for temperature detection and positioning of a cable joint, and belongs to the field of power cables. In particular, it relates to a cable joint for stable detection and positioning by directly embedding a stable sensor in a cable core and cooperating with an identification code. Background technique [0002] At present, as the country develops clean energy faster and faster, most of my country's wind power and photovoltaic power generation projects are built in remote areas such as mountains and deserts. The wires are relatively long, and cable trenches are usually not built. The positioning and maintenance of the intermediate joint is a difficult point; [0003] The existing technologies related to cable intermediate joints mainly have the following forms: [0004] (1) Directly buried connector, directly connect...

Problems solved by technology

[0004] (1) Directly buried connector, directly connect the cable, has no temperature measurement function, and cannot be found when the temperature exceeds the allowable value;

[0005] (2) For the laying of the cable trench, infrared temperature measuring equipment is used to measure the temperature, and the manhole cover needs to be opened to enter the cable trench, but the operation is inconvenient, and the real temperature inside the cable joint cannot be measured, and the measurement error is large;

[0007] The temperature measurement and positioning of the cable joints cannot be carried out in any of the above structures;

[0008] It is impossible to predict the use of cables and perform maintenance in advance, which is prone to unexpected shutdowns and economic losses
