Abstract
An intelligent monitor type ultra-high voltage cable accessory is provided, which comprises a stress cone, a sleeve, a cable conductor, a connection hardware fitting, a seal ring, an upper flange and a lower flange. The stress cone is bushed in the sleeve. The utility model is characterized in that: a measuring optical fiber and an optical fiber sleeve are pre-embedded in the sleeve; the measuring optical fiber is wrapped around the surface of the stress cone; the optical fiber sleeve passes appropriate position of the lower flange and is sealed and fixed; the measuring optical fiber leads out a measuring signal via the optical fiber sleeve and connect the measuring signal with an external measuring equipment. The utility model can be adopted to automatically monitor the insulation status inside the cable accessory, which effectively ensures the safety and reliability for the operation of the cable accessory and creates conditions for the timely spotting of problem and advanced inspection and repair. Besides, by adopting conical surface in connection, the utility model effectively prevents the insufficient connection due to unqualified installation and enhances the reliability.
Description
Technical field
The utility model relates to a kind of ultrahigh voltage cable fittings, and particularly a kind of intelligent monitoring ultrahigh voltage cable fittings is applicable to 110kV-220kV electric pressure crosslinked cable.
Background technology
Widely used electric cable accessories has cable outdoor terminal, cable combination terminal, cable GIS terminal, cable insulation indirect first-class in electrical power trans mission/distribution system at present, for example: Chinese patent 200520045566.2 disclosed a kind of " 220kV crosslinked cable outdoor terminal ", mainly form by stress cone, sleeve pipe, spring assembly, tail pipe etc.This electric cable accessories can be electrically connected with cable easily and effectively, but all electric cable accessoriess are after energising puts into operation at present, and existing major issue can be monitored its reliability of operation without any method exactly.Because of there not being automatic monitoring means, people can't detect the state of insulation of electric cable accessories inside in real time, and the main cause of accident appears in go wrong cable line often of electric cable accessories built-in electrical insulation.Cable line operation least reliable position is an electric cable accessories, from the recent statistics result as can be known, the cable line fault rate be because electric cable accessories causes more than 95%.Simultaneously at present the IEC60859 interface that uses of GIS cable termination all adopts the mode of plane contact to be connected with pre-buried top electrode in the epoxy cover, if install improperly, will cause contact resistance bigger, and the phenomenon of bad connection takes place.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of intelligent monitoring ultrahigh voltage cable fittings is provided, and can monitor its inner state of insulation automatically, can avoid taking place the phenomenon of bad connection, is applicable to 110kV-220kV electric pressure crosslinked cable.
Technical solution of the present utility model is: a kind of intelligent monitoring ultrahigh voltage cable fittings, its composition comprises that stress cone 1, sleeve pipe 2, cable conductor connect gold utensil 3, sealing ring 4, upper flange 5, lower flange 6 compositions, stress cone 1 is in sleeve pipe 2, it is characterized in that: also be embedded with measuring optical fiber 7 and ferrule 8 in the sleeve pipe 2, measuring optical fiber 7 is wrapped on stress cone 1 surface, ferrule 8 is by the appropriate location and the sealing and fixing of lower flange 6, measuring optical fiber 7 is drawn measuring-signal by ferrule 8, and links to each other with external measurement devices.
Use the utility model, can monitor the state of insulation of electric cable accessories inside automatically, guaranteed the security reliability of electric cable accessories operation effectively, in time pinpointing the problems, overhaul in advance the condition of having created; The utility model adopts the conical surface to connect, and has reduced effectively because of the bad harm that causes bad connection is installed, and has improved reliability.
Description of drawings
Fig. 1 cutaway view of the present utility model;
Below in conjunction with accompanying drawing the utility model is described in further details.
Embodiment
In Fig. 1, the utility model is formed and is comprised that stress cone 1, sleeve pipe 2, cable conductor connect gold utensil 3, sealing ring 4, upper flange 5, lower flange 6 compositions, stress cone 1 is in sleeve pipe 2, be embedded with measuring optical fiber 7 and ferrule 8 in the sleeve pipe 2, measuring optical fiber 7 is wrapped on stress cone 1 surface, ferrule 8 is by the appropriate location and the sealing and fixing of lower flange 6, and measuring optical fiber 7 is drawn measuring-signal by ferrule 8, and links to each other with external measurement devices.The signal of electric cable accessories inside and cable body is transferred on the outside terminating machine, thus the on-line monitoring of realization cable line.The measuring optical fiber 7 of electric cable accessories inside is mainly used in to be measured internal temperature and electric property or is used for a part as the optical fiber communication of conducting cable body; Ferrule 8 is the transition bodies as measuring optical fiber outgoing cable annex, and it had both had the effect of infrared optical fiber in the conducting, and it also has the function that prevents that electric cable accessories built-in electrical insulation oil from leaking simultaneously.
