Abstract
An intelligent monitor super-high voltage cable accessory includes a stress cone, a sleeve, connecting tools of cable conductors, sealing coils, upper flange and a lower flange, and the stress cone is in the sleeve characterizing: a measurement fiber and a fiber sleeve are pre-buried in the sleeve, and the measurement fiber is winded on the surface of the stress cone, the fiber sleeve is sealed and fixed through a suitable place of the lower flange, the measurement fiber leads out measurement signals by the fiber sleeve and connected to outside measurement devices, which can monitor the insulation state inside of cable accessories.
Description
Technical field
The present invention relates to a kind of ultrahigh voltage cable fittings, 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 objective of the invention is to overcome the deficiencies in the prior art, a kind of intelligent monitoring ultrahigh voltage cable fittings is provided, can monitor its inner state of insulation automatically, can avoid taking place the phenomenon of bad connection, be applicable to 110kV-220kV electric pressure crosslinked cable.
Technical solution of the present invention 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 present invention, 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 present invention 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 invention;
Below in conjunction with accompanying drawing the present invention is described in further details.
Embodiment
In Fig. 1, the present invention forms and 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, 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.
