Description
Technical field
The utility model relates to a kind of terminal connection box for optical phase conductor, is a kind of 220KV of being used for OPPC (OPPC) cable splice closure.
Background technology
Conventional OPPC (OPPC) no-go sub box is that leading in cable is directly passed composite hollow insulator, easily at hollow formation discharge path; OPPC adopts parallel groove clamp with being connected of connector box, and suitable cable footpath scope is little, and there is point discharge in angular place; Simultaneously, in high-voltage circuit, the insulator sheet number of insulator chain is a lot, voltage skewness on every insulator, first insulator near lead born very high voltage, and therefore, the deterioration rate of first insulator is very high, for the voltage that improves insulator in the insulator chain distributes, grading ring need be installed on composite insulator.
Summary of the invention
The purpose of this utility model is to provide a kind of terminal connection box for optical phase conductor at above-mentioned weak point, be applicable to OPPC (OPPC) the no-go sub box of 220kV electric pressure, the centre wears the hollow parts filled silicon rubber of light unit, whole wire clamp replaces parallel groove clamp, between box body and insulator, increase grading ring, alleviate the deterioration of insulator, increase anti-sealing access to plant in cover rim.Compare with ordinary optic fibre composition phase conductor (OPPC) connector box, have reliable in mechanical performance, electric property excellence, sealing property is good, material is corrosion-resistant, inner structure is more suitable in the connection of optical cable and installation.
Terminal connection box for optical phase conductor is to take following technical scheme to realize:
Terminal connection box for optical phase conductor has upper cartridge body and lower box body, between upper cartridge body and lower box body composite hollow insulator is installed, and between upper cartridge body and composite hollow insulator grading ring is installed; OPPC (OPPC) wire clamp is housed on upper cartridge body, enters place, cable hole skirt, rubber ring I and nut are housed; Entering inside, cable hole, rubber cone I and little pressure ring I are being housed; In the bottom of upper cartridge body, big pressure ring 8, little pressure ring I I and rubber cone II are housed; Support screw I, the fine plate I of dish are installed on big pressure ring and coil fine plate lid I; On the top of upper cartridge body gasket seal and loam cake are installed; Inside at composite hollow insulator penetrates fiber unit, all the other space filling gels; Lower box body adopts with composite hollow insulator and is threaded, and lower box body is equipped with the packoff of fiber unit, and the packoff of fiber unit comprises rubber cone II I and little pressure ring I II; At the introducing cable place of lower box body, be equipped with and introduce cable clip tool, rubber ring II and nut II; In lower box body inside optical fiber storage device is housed, optical fiber storage device comprises fine plate II of dish and the fine cover plate II of dish; In the lower box body bottom surface mounting seat is housed.
When terminal connection box for optical phase conductor (220kVOPPC no-go sub box) uses, can install leading in cable earlier, and with the fiber unit welding of centre; Again whole connector box is installed on the mounting platform of shaft tower, OPPC (OPPC) is fixed on OPPC (OPPC) wire clamp, finish sealing and install, fused fiber splice, last, gasket seal is installed, build loam cake.
Terminal connection box for optical phase conductor is simple in structure, and integral sealing is reliable, the mechanical property height, decay resistance is superior, the inner installing space of box body is big, to fiber reel around or other operations, safeguard and bring convenience.
The terminal connection box for optical phase conductor structure has upper and lower box body, middle connection composite hollow insulator, OPPC advances cable and packoff, introducing cable advance cable and seal element and mounting seat, and is reasonable in design, compact conformation.Because OPPC (OPPC) wire clamp adopts whole parallel groove clamp, suitable cable footpath scope is big, does not have wedge angle, reduces point discharge; Grading ring is installed on composite hollow insulator, and the voltage that improves insulator in the insulator chain distributes; The space of fiber unit does not need to irritate at the scene oil, and filling gel is installed in advance in factory, alleviates on-the-spot workload, and sealing is reliable.Owing between loam cake and the upper cartridge body gasket seal is housed, have waterproof construction, reduce the possibility that water enters the upper cartridge body sealing surface.
