Problems solved by technology

However, the existing cable connection and temperature measurement system connection technologies are all single-function extension accessories.
Instead of comprehensively considering the two systems together, the mutual influence and function
The built-in temperature measurement unit of common ultra-high voltage smart cables, or the type with copper wire shielding, or the temperature measurement unit is placed between the aluminum sheath and the cable core, and the optical fiber of the temperature measurement unit is easily broken and damaged. The unit is composed of optical fiber, loose sleeve, filler, reinforcement and metal sheath. The metal sheath will form a floating potential under the high-voltage electric field of the cable. If it is not handled properly, it will cause distortion to the electric field at the cable terminal. influences

Abstract

The invention relates to an intelligent cable connector. The intelligent cable connector has functions of a cable extending connector and an insulated connector. Besides, the intelligent cable connector is provided with a photoelectric extending connector which comprises semiconductive photoelectric separation fingerstalls, optical fiber protective jackets, an optical fiber connector, and heat-insulation binding belts, wherein the semiconductive photoelectric separation fingerstalls are both cylindrical heat shrinking tubes which are prefabricated with selective semiconductive material and are of one-in and two-out structure or one-in and multi-out structure, and are fastened to a metal shielding layer through the heat-insulation binding belts, the optical fiber protective jackets are metal jackets replacing a temperature measuring unit, and are matched with the photoelectric separation fingerstalls to protect temperature measuring fibers from being damaged, the number of the photoelectric separation fingerstalls is two, and the photoelectric separation fingerstalls ensure photoelectric separation. According to the intelligent cable connector, an original insulator structure and an original electric field structure are not damaged, photoelectric performance of an original product is not reduced, and meanwhile a function of on-line accurate monitoring of cable temperature is achieved.

Description

technical field [0001] The invention relates to a cable connector, in particular to an intelligent cable connector capable of ensuring insulation and electric field structure and realizing online accurate monitoring of cable temperature. Background technique [0002] With the rapid development of my country's national economy, the demand for electricity has increased significantly. The State Grid announced the preliminary construction plan of the smart grid, proposing to establish a unified and strong smart grid, based on the principles of unified planning, unified standards, and unified construction. The backbone grid structure, the coordinated development of power grids at all levels, and the construction of a national grid featuring informatization, automation, and interaction. Among them, "unity" is the premise, "strength" is the foundation, and "intelligence" is the key. The high degree of integration of unity, strong grid structure and intelligence determines the futur...
