Description
Technical field
The present invention relates to insulation cable splice closure, particularly a kind of 500kV transmission line of electricity OPGW(Optical Fiber composite overhead Ground Wire that a kind of transmission line of electricity uses) ground wire ice melting graded insulation cable joint box.
Background technology
Along with the fast development of electrical networks at different levels, as the OPGW(Optical Fiber composite overhead Ground Wire of lightning conducter and communication port dual-use function) bringing into play more and more important effect in power communication system at home and abroad.China since twentyth century the eighties introduce the OPGW(Optical Fiber composite overhead Ground Wire) use since, the OPGW(Optical Fiber composite overhead Ground Wire) all adopt the method for operation by tower ground connection always.But research is thought, the OPGW(Optical Fiber composite overhead Ground Wire) adopt the method for operation by tower ground connection, ground wire employing single-point grounding will cause very large energy consumption, do not meet the trend of current national development resource-conserving electrical network, and this method of operation still causes the OPGW(Optical Fiber composite overhead Ground Wire) one of disconnected strand the reason of being struck by lightning repeatedly.
The ground wire insulator arrangement is had higher requirement, mainly have the problem of following three aspects: during insulation: 1) when the OPGW(Optical Fiber composite overhead Ground Wire) charged after, requirement is in the place's photoelectricity reliable separation that continues, because OPGW is that whole dish is installed, may all must change by whole dish optical cable in case break down, therefore high to the security requirement of equipment; 2) this equipment as a kind of protective device that continues, must have good mechanical property, environmental performance, electric property; 3) must reliably insulate with connecting portion, guarantee safe distance.
Summary of the invention
The objective of the invention is provides a kind of ground wire ice melting graded insulation cable joint box for above-mentioned weak point, reasonable in design, good seal performance, and it is convenient to open.Facilitate welding and maintenance, realize optical signal transmission; When the thunderbolt optical cable, connector box guarantees the line security reliability service by insulator and tower insulation.
ground wire ice melting graded insulation cable joint box takes following technical scheme to realize: ground wire ice melting graded insulation cable joint box comprises optical cable fixing device, the optical fiber memory storage, composite hollow insulator and seal, be separately installed with composite hollow insulator and optical cable fixing device at optical fiber memory storage two ends, the two ends of optical fiber memory storage are respectively arranged with internal thread, composite hollow insulator one end is provided with external thread, composite hollow insulator one end matches by the internal thread of external thread with the optical fiber memory storage, two composite hollow insulators are separately fixed at optical fiber memory storage two ends, the composite hollow insulator other end and optical cable fixing device crimping secure fit, optical fiber memory storage bottom is provided with internal thread, seal comprises solid insulator and mounting seat, solid insulator is arranged on mounting seat, solid insulator top is provided with external thread and matches with the internal thread of optical fiber memory storage bottom setting, and solid insulator is fixed on bottom the optical fiber memory storage.
Described optical fiber memory storage is provided with fiber storage tray.
Described optical cable fixing device comprises fixedly fixture block, geometrical clamp body and fixed screw, is provided with optical fiber on the geometrical clamp body and advances the cable mouth, is provided with fixedly fixture block on geometrical clamp body top, clamps optical cable by fixed screw.
Ground wire ice melting graded insulation cable joint box is applicable to 500kV transmission line of electricity OPGW(Optical Fiber composite overhead Ground Wire) ground wire deicing graded insulation cable connection, during use, the OPGW optical cable passes through composite hollow insulator, enter into the optical fiber memory storage and continue, and the geometrical clamp body by optical cable fixing device adopts, and fixedly fixture block and fixed screw are fixed.
Advantage of the present invention: ground wire ice melting graded insulation cable joint box is reasonable in design, good seal performance, and it is convenient to open.Be applicable to 500kV transmission line of electricity OPGW(Optical Fiber composite overhead Ground Wire) ground wire deicing graded insulation cable connection, facilitate welding and maintenance, realize optical signal transmission; When the thunderbolt optical cable, connector box guarantees the line security reliability service by insulator and tower insulation.
When the OPGW(Optical Fiber composite overhead Ground Wire) charged after, in the place's photoelectricity reliable separation that continues; This equipment has good mechanical property as a kind of protective device that continues, environmental performance, electric property; Reliably insulate with connecting portion, guarantee safe distance.
