Abstract
The invention provides a fiber composite high voltage power cable which comprises a conductor unit and a sheath unit. A buffer water blocking layer is provided outside the conductor unit. The buffer water blocking layer is provided with a fiber unit and two soft wires inside. The fiber unit and the two soft wires are parallel with a distance. Compared with a traditional fiber temperature measurement system, the invention provides the fiber composite high voltage power cable of which the fiber unit is directly embedded into a cable structure. The fiber composite high voltage power cable has the following advantages that: 1. manufacture of a temperature measurement optical cable protection layer is saved, a stainless steel sleeve pipe is directly employed, a metal sheath and an oversheath of the cable are taken as a protection layer, and manufacture cost of a temperature measurement optical cable is reduced; 2. all cost of temperature measurement optical cable laying and installation are saved, and cost of a high voltage power transmission system is reduced. A corrugated aluminum sheath employed in the invention has a certain cushioning effect on extraneous impact, and destruction of a fiber structure by the extraneous impact can be substantially reduced.
Description
Technical field
The present invention relates to a kind of high voltage power cable, be specifically related to a kind of adopt fiber unit dredge around mode introduce the optical fiber composite high pressure power cable of thermometric optical fiber.
Background technology
At present, in the high-tension electricity transmission line, often adopt optical fiber temperature measurement system to come the temperature of Monitoring High Voltage Cable each point.Optical fiber temperature measurement system is along the cable laying temperature measuring optical cable, and what temperature measuring optical cable can be continuous obtains along the temperature of high-tension cable every bit.
A large amount of expense of wanting is installed, lays and is safeguarded in the manufacturing of temperature measuring optical cable.
Summary of the invention
Technical problem to be solved by this invention provides a kind of optical fiber composite high pressure power cable, can embed the normal operation that the optical cable unit also can guarantee fiber unit.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of optical fiber composite high pressure power cable, comprise conductor element and sheath unit, outside conductor element, be provided with the buffering water blocking layer, be provided with fiber unit and two soft threads for thermometric in the buffering water blocking layer.
Described fiber unit and be positioned at two soft threads of fiber unit both sides parallel dredge around.
In the described fiber unit, optical fiber places in the stainless steel sleeve pipe, and becomes matched in clearance.
The slightly larger in diameter of described soft thread (5) is in the external diameter 0.5-2mm of stainless steel sleeve pipe.
Described soft thread is annealed aluminum wire or paper string.
Described annealed aluminum wire is connected to each other and ground connection.
Described buffering water blocking layer is made up of semi-conductive buffer water-blocking band and semiconductive tinned copper wire mask tape.
In the described sheath unit, be provided with corrugated aluminum sheath in the oversheath.
In the described conductor element, conductor is provided with conductor shield, insulating barrier and insulation screen outward.
A kind of optical fiber composite high pressure power cable provided by the invention is compared with the conventional optical fibers temp measuring system, fiber unit is directly embedded in the construction of cable have the following advantages:
1, saves the manufacturing of temperature measuring optical cable protective layer, directly adopted the stainless steel sleeve pipe, as protective layer, reduced the manufacturing cost of temperature measuring optical cable with the metallic sheath of cable and oversheath.
2, save all expenses that temperature measuring optical cable lays and installs, reduced the expense of high-tension electricity transmission system.
The corrugated aluminum sheath that adopts among the present invention impacts to external world certain cushioning effect, can reduce it greatly to the destruction of fiber unit.
Select for use two slightly larger in diameter in the annealed aluminum wire (or paper string) of stainless steel sleeve pipe parallel dredge around advantage be: annealed aluminum wire (or paper string) is more docile first, dredge around the time with stainless loose to overlap tube pitch less.When cable is subjected to the footpath outward force, can avoid occurring prior to stainless pipe pine sleeve stress:
1), overlaps the situation of the stainless steel sleeve pipe that breaks in the embossing process at aluminium;
2), distortion or bending appear in the stainless steel sleeve pipe when cable carrying and laying installation.
And thin winding technologe is simple, and equipment investment is little.The thin journey of walking around of optical cable of the present invention unit and soft thread only needs a steel wire armouring machine to finish, and production technology is simple, and equipment investment is little; Thermometric optical fiber and electric power transfer are used identical carrier, make ultra-high-tension power transmission line monitor the insulation working temperature in transferring electric power, understand the insulation operating state at any time; Greatly reduce the laying installation cost, the amount of reduction is equal to the expense that fiber cable laying is installed basically.
