Technical field
The utility model relates to the insulation cable splice closure that a kind of transmission line of electricity uses, particularly a kind of 500kV transmission line of electricity OPGW (OPGW) ground wire deicing graded insulation cable splice closure.
Background technology
Along with the fast development of electrical networks at different levels, bringing into play more and more important effect in the power communication system at home and abroad as the OPGW (OPGW) of lightning conducter and communication port dual-use function.China is since twentyth century, the eighties was introduced OPGW (OPGW) application, and OPGW (OPGW) all adopts the method for operation by tower ground connection always.But research is thought; OPGW (OPGW) adopts by tower ground connection, ground wire and adopts the method for operation of 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 OPGW (OPGW) one of disconnected strand the reason of being struck by lightning repeatedly.
The ground wire insulator arrangement is had higher requirement; The problem that mainly has following three aspects during insulation: 1) after OPGW (OPGW) is charged; Requirement is in the place's photoelectricity reliable separation that continues; Install because OPGW is whole dish, possibly put in order the dish optical cable and all must change in case break down, therefore high to the security requirement of equipment; 2) this equipment must have the favorable mechanical performance as a kind of protective device that continues, environmental performance, electric property; 3) must reliably insulate with connecting portion, guarantee safe distance.
Summary of the invention
The purpose of the utility model is to above-mentioned weak point a kind of ground wire deicing graded insulation cable splice closure to be provided, and is reasonable in design, good seal performance, and it is convenient to open.Make things convenient for welding and maintenance, realize optical signal transmission; When the thunderbolt optical cable, connector box guarantees the line security reliability service through insulator and tower insulation.
Ground wire deicing graded insulation cable splice closure takes following technical scheme to realize: ground wire deicing graded insulation cable splice closure comprises optical cable fixing device, 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 through the internal thread of external thread with the optical fiber memory storage, and 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 installed on the mounting seat; Solid insulator top is provided with external thread and matches with the internal thread that optical fiber memory storage bottom is provided with, and solid insulator is fixed on optical fiber memory storage bottom.
Said optical fiber memory storage is provided with the fine dish of storage.
Said optical cable fixing device comprises fixedly fixture block, geometrical clamp body and fixed screw, and the geometrical clamp body is provided with optical fiber and advances the cable mouth, is provided with fixedly fixture block on geometrical clamp body top, clamps optical cable through fixed screw.
Ground wire deicing graded insulation cable splice closure is applicable to 500kV transmission line of electricity OPGW (OPGW) ground wire deicing graded insulation cable connection; The OPGW optical cable passes through composite hollow insulator during use; Enter into the optical fiber memory storage and continue, and the geometrical clamp body through optical cable fixing device adopts, and fixedly fixture block and fixed screw are fixed.
The advantage of the utility model: ground wire deicing graded insulation cable splice closure is reasonable in design, good seal performance, and it is convenient to open.Be applicable to 500kV transmission line of electricity OPGW (OPGW) ground wire deicing graded insulation cable connection, make things convenient for welding and maintenance, realize optical signal transmission; When the thunderbolt optical cable, connector box guarantees the line security reliability service through insulator and tower insulation.
After OPGW (OPGW) is charged, in the place's photoelectricity reliable separation that continues; This equipment has the favorable mechanical performance as a kind of protective device that continues, environmental performance, electric property; Reliably insulate with connecting portion, guarantee safe distance.
