Description
Technical field
What the energy-conservation connector box of OPGW of the present invention related to is the energy-conservation connector box of a kind of OPGW, is a kind of OPGW (OPGW) cable splice closure that is used for.
Background technology
Along with the continuous development of electrical network, the OPGW optical cable at home and abroad is widely used in the power communication system, and is developed rapidly.The OPGW optical cable is used for transmission of Information as optical cable on the one hand in application on power system; On the other hand, as the ground wire of circuit, play lightning-arrest effect.When transmission line of electricity normally moves, can generate an electromagnetic field around the lead, can produce electromagnetism and electrostatic field coupling between ground wire and the lead, because the distance of ground wire to each phase conductor is generally unequal, the mutual inductance between them just has difference.Therefore, induction produces longitudinal induction electromotive force and the electrostatic induction voltage that distributes along the line on ground wire.When OPGW and common ground wire during, will between OPGW, common ground wire and the earth, form electric current, thereby produce certain electric energy loss all by tower ground connection.
Because technical merit is limited, and the OPGW optical cable is difficult to realize graded insulation,, still cause the electric energy loss of transmission line of electricity to a certain extent for a long time so still adopt mode by tower ground connection.Simultaneously, different because of common lightning conducter on the same tower and OPGW earthing mode make OPGW increased by lightning strike probability, and OPGW is easy to generate a disconnected burst of damage problem.
Summary of the invention
The objective of the invention is provides a kind of OPGW energy-conservation connector box to above-mentioned weak point, under the prerequisite that guarantees the OPGW optical cable performance, adopts the graded insulation single-point grounding; Reduce the induction current loss that OPGW optical produces by tower ground connection; When being struck by lightning, through upper/lower electrode striking conducting electric current; Through tower ground connection, play lightning protection function.
The energy-conservation connector box of OPGW is to take following technical scheme to realize:
The energy-conservation connector box of OPGW has upper cartridge body and lower box body; Between upper cartridge body and lower box body, composite hollow insulator is installed; Between the upper flange at composite hollow insulator two ends and lower flange, the discharging gap device is installed; The discharging gap device comprises top electrode and bottom electrode, and bottom electrode is provided with the striking convexity, and distance is 5～7mm between the striking convexity of top electrode and bottom electrode; OPGW optical cable fixing clamper one is housed on upper cartridge body, enters place, cable hole at upper cartridge body skirt one, rubber blanket one and hold-down nut one are housed; It is inner to enter the cable hole at upper cartridge body, and rubber cone one and nut one are housed.In upper cartridge body inside optical fiber memory storage one is housed, optical fiber memory storage one comprises fine plate of dish and the fine cover plate of dish; On the top of upper cartridge body O-ring seal one and loam cake are installed; Inner at composite hollow insulator, be coated with fiber unit, insulating medium is filled in all the other spaces.O-ring seal three is installed between the upper flanges of upper cartridge body and composite hollow insulator.
At lower box body OPGW optical cable fixing clamper two is housed, enters place, cable hole at lower box body skirt two, rubber blanket two and hold-down nut two are housed; It is inner to enter the cable hole at lower box body, and rubber cone two and nut two are housed.In lower box body inside optical fiber memory storage two is housed, the optical fiber memory storage comprises fine plate of dish and the fine cover plate of dish; In the lower box body bottom surface O-ring seal two and mounting seat are housed.Between the following end flanges of lower box body and composite hollow insulator, O-ring seal four is installed.
When the energy-conservation connector box of OPGW uses, can install the lower box body leading in cable earlier, and with the fiber unit welding of centre; Again the upper cartridge body leading in cable is fixed, accomplished sealing and install, fused fiber splice, last, O-ring seal is installed, build loam cake.
OPGW penetrates into cable conduit; And with one clamping of OPGW optical cable fixing clamper; In the upper cartridge body on top, continue, leave in the optical fiber memory storage one with the pre-buried fiber unit that is applied in the energy-conservation connector box of OPGW; The other end continues with identical method, and leaves in the lower end optical fiber memory storage two.OPGW optical is to the insulation of all fronts road during operate as normal, and when be struck by lightning OPGW or line fault caused occurring the transient state high pressure on the OPGW, OPGW then passed through top electrode, bottom electrode, the protruding striking conducting of striking electric current ground connection.Top electrode, bottom electrode clearance distance can be according to the electric pressure adjustment of transmission line of electricity.When transmission line of electricity normally moves, can generate an electromagnetic field around the lead, can not form backflow between OPGW, shaft tower and the earth, significantly reduce the electric energy loss that transmission line of electricity produces.Can reduce OPGW greatly and suffer lightning strike probability,, and then have positive effect building " energy-saving, environment-friendly type " transmission line of electricity for electric system brings huge economic benefit.
The energy-conservation connector box of OPGW is simple in structure, and integral sealing is reliable, and mechanical property is high, and decay resistance is superior, operation, easy to maintenance.
The energy-conservation connector box structure of OPGW has upper and lower box body, middle connection composite hollow insulator, enters the cable hole, goes out cable hole, packoff, seal element and mounting seat.The space of fiber unit does not need to irritate at the scene oil, fills medium and installs in advance in factory, alleviates on-the-spot workload, and sealing is reliable.Under the prerequisite that guarantees the OPGW properties of optical fiber cable, adopt the graded insulation single-point grounding, reduce the induction current loss that OPGW produces by tower ground connection, when being struck by lightning, through top electrode, bottom electrode, the protruding striking conducting of striking electric current through tower ground connection, plays lightning protection function.
The present invention to reduce the ground wire electric energy loss, reaches energy-conservation purpose owing to adopt graded insulation single-point grounding mode.Because adopt the energy-conservation connector box of OPGW of the present invention, OPGW optical plays the double action of lightning conducter and communication port.
