Application of composite power cable GIS terminal with optical fiber arranged in center of conductor

Abstract

The invention relates to an application of a composite power cable GIS terminal with an optical fiber arranged in the center of a conductor. The application comprises the following operation steps of: setting the reserved length of a cable, exposing the core of the cable, splitting a round cable split conductor and leading out the optical fiber with a stainless steel jacket from a gap between two fan-shaped conductor units; after cutting off a part of the round cable split conductor, crimping the optical fiber with a cable conductor lead-out bar; sleeving a corresponding terminal component and penetrating the led-out bare optical fiber into a small reserved hole of an insulating sleeve; leading the optical fiber out of a terminal from a lower reserved sealing armour clamp hole and then sealing the reserved hole; and finally, carrying out other mounting works of the terminal. The invention solves the problems that the traditional temperature measuring optical fiber cannot monitor the operation temperature of the terminal, binding posts of the traditional cable terminals are complicated to process and troublesome to operate, and the like; in addition, the invention has simple and convenient process and easy operation, meets the automatic monitoring requirements on on-line real-time temperature detection, aging monitoring, real-time fault monitoring and early warning of the safe operation of a power cable line, obviously improves the reliability and the efficiency of construction works and reduces the construction cost.

Description

technical field [0001] The invention relates to a connection method of a GIS (Gas Insulated Switch Station) terminal for cross-linked polyethylene insulated power cable lines, in particular to the application of a GIS terminal for a composite power cable in which an optical fiber is arranged in the conductor center, which is mainly used for connecting The temperature-measuring optical fiber is directly set in the composite power cable in the center of the twisted circular split conductor, and is connected to the optical fiber of the temperature control box of the GIS equipment through a dedicated GIS terminal. Background technique [0002] With the development and application of distributed optical fiber sensing technology, in order to ensure the safe operation of the transmission of strong electric energy in the power cable line, the power department requires the use of temperature measuring optical fiber to carry out the following automatic monitoring of the safe operation ...
