Abstract
The utility model discloses a temperature sensing optical cable comprising optical fibers (1), fiber ointment (2), optical fiber loose sleeves (3), and an outer sheath (5), wherein, the optical fibers (1) are coated by the optical fiber loose sleeves (3), the optical fiber loose sleeves (3) are filled with the fiber ointment (2), the utility model is characterized in that two sides of the optical fiber loose sleeves (3) are respectively parallel arrayed with nonmetal reinforcements (4), and a layer of PE outer sheath (5) is coated on the external of the nonmetal reinforcements (4) which are parallel-arrayed with the optical fiber loose sleeves (3). The utility model provides an optical fiber temperature sensing measurement system which is assembled with a light sense temperature controller, when it is applied to a power circuit, the temperature changing of the whole circuit can be monitored, the precision is higher, the recovery service is convenient, no induced voltage is generated in running, and the tensile strength and the resist side-compression ability can be strengthened.
Description
Affiliated technical field
The utility model relates to a kind of improvement of cable configuration, is a kind of optical cable that can detect the temperature variation of whole cable line specifically.
Background technology
Traditionally, be the position that places cable to break down easily temperature sensor or thermopair to the temperature monitoring system of cable, as cable intermediate joint, cable termination, cable near the place of thermal source or the place of cable improper ventilation.Adopt the said temperature supervisory system, local temperature that can only the detection streamer circuit changes.A kind of complex structure of employing, the high temperature-sensitive optical fiber of cost are also arranged, the variation that comes the detection streamer line temperature.This temperature-sensitive optical fiber is wrapped on the cable sheath, perhaps is placed on the inside of cable.The temperature-sensitive optical cable of this structure adopts stainless steel sleeve pipe or metal tape armour, makes in the temperature-sensitive optical cable to have induced voltage, to the security presence hidden danger of the person.The optical cable of this structure adopts non-ferrous metal to make in addition, the cost height, and weight is big, and the xsect of product structure adopts circular, is vulnerable to the damage of external force.Before the utility model design is finished, not seeing the temperature-sensitive optical cable identical with the utility model structure uses in people's routine work, not seeing the temperature-sensitive optical cable identical with the utility model structure has sale, and it is on the books in the literature also not see the temperature-sensitive optical cable identical with the utility model structure.
Summary of the invention
The purpose of this utility model is to provide a kind of temperature-sensitive optical cable, the temperature detected by optical fiber formula measuring system that this optical cable and light sensation temperature controller are formed, be applied to power circuit and can monitor the situation of the temperature variation of whole circuit, the degree of accuracy of measuring is high, but also be convenient to repairing, in addition, it does not adopt metal material, there is not the potential safety hazard to the person in the induced voltage that do not produce in service.
For achieving the above object, the utility model adopts following technical proposals:
A kind of temperature-sensitive optical cable, comprise optical fiber, fine cream, optical fiber loose tube and oversheath, the optical fiber loose tube clad optical fiber, fill fine cream in the optical fiber loose tube, the non-metal reinforcement member that respectively is arranged in parallel in the optical fiber loose tube both sides coats one deck PE oversheath in the non-metal reinforcement member outside that is arranged in parallel with optical fiber loose tube then.
In technique scheme, said optical fiber is Ala type multimode optical fiber.
In technique scheme, said non-metal reinforcement member is made for the FRP material.
In technique scheme, said optical fiber loose tube is made for the PBT material.
The utility model has more following effects and good effect:
The utility model provides a kind of temperature-sensitive optical cable, the temperature detected by optical fiber formula measuring system that this optical cable and light sensation temperature controller are formed, be applied to power circuit and can monitor the situation of the temperature variation of whole circuit, the degree of accuracy of measuring is high, but also be convenient to repairing, it does not adopt metal material, and there is not the potential safety hazard to the person in the induced voltage that do not produce in service.In addition, because the employing of non-metal reinforcement member neither produces induced voltage, tensile strength and lateral pressure resistant ability have been strengthened again.
