Open-air optical cable welding construction in a kind of winter utility unit
Technical field
The present invention is applicable to that winter, open-air communication cable set up the optical cable welding in the work.
Background technology
In the handshaking procedure of optical fiber, receive the influence of external environment factor (temperature, moisture, air degree of purity, nuclear radiation and various electromagnetic environment) to some extent, the method for fibre junction has three kinds of weldings, flexible connection, mechanical connection.In engineering, mostly adopt burning-on method.Adopt the contact loss of welding process little, reflection loss is little, and reliability is high.But open-air welding optical cable causes heat sealing machine to start easily under the condition of low temperature, cold; Open-air welding optical cable very easily causes optical fiber to fracture and phenomenon such as welding degradation under low temperature, cold condition, has influenced in the transmission course of optical fiber problems such as signal loss greatly.
Summary of the invention
In order to overcome the deficiency of above-mentioned several respects problem, the present invention provides open-air optical cable welding construction in a kind of winter utility unit.
The technical solution adopted for the present invention to solve the technical problems is: use and be convenient to field construction and single tent easy to carry; Portable minitype gas dynamotor provides electric power for the bulb that is used to heat up and throw light on; The insulating board that is easy to carry and fixes constitutes lampshade two bulbs is combined into the intensification lighting apparatus, and the tent inner top is provided with hook, and the intensification lighting apparatus hangs over the tent inner top and uses, and in tent, carries out the optical cable welding.
Tent stops extraneous cold air with dustproof, and the single tent that places starts generating with gasoline engine generator, utilizes small-sized intensification, lighting apparatus heating, daylighting, in tent, carries out the optical cable welding, is easy to carry and fixes.
Open-air optical cable welding construction in this winter utility unit comprises and is convenient to field construction and the single tent that carries; Portable minitype gas dynamotor; The intensification lighting apparatus that is easy to carry and fixes, the tent inner top is provided with hook, and the intensification lighting apparatus hangs over the tent inner top; In tent, carry out the optical cable welding.The intensification lighting apparatus constitutes lampshade by insulating board and two bulbs combine.Bulb in the intensification lighting apparatus is a high power intensification lighting bulb.
The invention has the beneficial effects as follows that device volume is little, in light weight, be easy to carry, and convenient and flexible operation, only need two people just can safety operation: a people props up tent, operate generator, and a people is responsible for that the welding optical cable gets final product in tent.Open-air OPGW optical cable welding in winter experiment showed, respond well, and the welding attenuation meets technical stipulation index and requirement.In the open-air in the winter time optical cable welding construction; This invention has reduced workload, has saved the operating time, has solved under low temperature, cold condition open-air welding and has very easily caused optical fiber to fracture and phenomenon such as welding degradation; Improve operating efficiency greatly, created considerable economic.

The specific embodiment
The staff puts on work clothes, be with safety helmet, wear optical cable welding work uses gloves; Prop up good tent, it can not be swung, a people gets in the tent, in tent, is ready to workbench and optical cable butt fusion tool; Connect the generator wiring, fix intensification, lighting apparatus, start small generator; After treating that temperature reaches requirement, carry out optical cable welding work.
