Description
Technical field
The utility model relates to high pressure/ultrahigh voltage power electric cable accessories, particularly a kind of high voltage power cable terminal of conductor built-in optical cable.This terminal comprised conductor binding post, high-pressure side, hold and the unit that insulate, the insulation unit is set between described high-pressure side and the ground end, the conductor binding post is arranged on high-pressure side.
Background technology
For guaranteeing the safe operation of high pressure underground cable system, power department carries out on-line monitoring to it.The main contents of on-line monitoring comprise load monitoring and two aspects of malfunction monitoring.
The operating temperature limit that the constraints of the load-bearing capacity of cable mainly allows from cable and electric cable accessories manufactured materials.For example, for XLPE cable, the temperature of cable conductor, the temperature of the XLPE of adjacent conductors just, regulation can not surpass 85 degree usually.When cable and cable system design, mainly limit and finish the load-bearing capacity design according to conductor temperature.The load-bearing capacity of cable system is usually according to IEC60287 and IEC853 standard design.These standards hypothesis load currents are constant or substantially according to a daily load curve modal shift, and the hypothesis ambient environmental conditions is determined.For guaranteeing design safety, the condition of being supposed is often got extreme case, causes the possibility that the load of cable system actual motion is low, assets utilization is not enough.In fact, because cable electric influences each other and thermal conduction study the complex nature of the problem, above-mentioned standard can not provide reliably and accurately and separate for the cable of (particularly multiloop) that lays in the environment of more complicated.Cable temperature is carried out online detection, an approach that addresses this problem is provided, conductor temperature is very important, can be directly as the key index of load monitoring.
Environmental condition around the actual motion cable system is complicated, and its state might move, and is very uncertain, and therefore the Temperature Distribution of detection streamer total length can't not judged the peak of whole cable temperature reliably.The cable temperature peak is actual load bottleneck point.More complicated situation is, the position of the load bottleneck point on same cable changes, and in a period of time, a plurality of bottleneck point may appear in same cable.
Distributed fiber temperature sensing (Distributed Temperature Sensor is hereinafter to be referred as DTS) technology provides secure solution for the online load monitoring of cable.Utilize the DTS technology, can detect a Temperature Distribution that reaches several kms to tens km optical fiber, the sampled point distance can reach 1 to 2 meter.This thermometric optical fiber is axial arranged along cable, and the axial temperature that then can obtain cable distributes.
Up to the present, it has been generally acknowledged that,, do not allow the insulating barrier parcel that destroys by integrality because the conductor of high-tension cable is in high-voltage potential, can't be on conductor or inner and be drawn out to the outside that is in earth potential with fiber arrangement.So it is infeasible utilizing the DTS technology directly to measure conductor temperature.Common way has two kinds at present:
1, external: the optical cable that will hold thermometric optical fiber is arranged in cable surface;
2, built-in: in the cables manufacturing stage, with thermometric optical fiber or optical cable join certain outer layer of cable insulation or certain two-layer between, typically outside the semiconducting insulation shielding, in the metallic sheath.
At this moment, though the temperature of measurement is not the temperature of cable conductor, but still has important value.And, be external boundary with thermometric optical fiber, cable is set up heat transfer partial differential equation model, continue real-time load current of input and real-time fiber optic temperature, can calculate the cable conductor temperature.Korean Patent Publication No. 2003-45864 has disclosed a kind of system that a temperature survey optical fiber is used to calculate the underground power cable conductor temperature that is provided with in cable.
About external:, can optical cable be fixed on cable surface by artificial employing colligation or bonding method for cable in the cable tunnel and the direct-buried cable before the backfill earthwork.But for the cable that the comb mode is laid, optical cable draws in the comb usually after cable pipe finishes again.At this moment, unlikely as closely contacting cable surface in the above-mentioned situation, the part optical cable may contact cable surface to optical cable, and part then may not touch cable and in the unsettled medium in comb.This will make model introduce uncertain factor, cause the bigger error of calculation.
About built-in: Chinese patent publication number CN1624812A, Japanese patent application publication No. 1990-144810,1994-148001,1994-181013,1994-181014 and 1994-181015 have disclosed multiple fiber composite power cable.They all are arranged in optical cable between cable insulation and the sheath, belong to built-in.In built-in fiber composite power cable, optical cable very as one man is in certain outer one deck of cable insulation, has solved the problem of above-mentioned external, but must handle the connectivity problem of cable joint place optical fiber, and this makes the cable joint installation process become complicated.Usually will adopt a wire jumper optical cable, two welding points are respectively with the fiber optic tap welding of two cables.That is to say that in order to monitor the Temperature Distribution of a cable, the quantity of the welding point on the thermometric optical fiber is the twice of cable joint quantity at least.For long cable, the quantity of fused fiber splice point may be too many.The fused fiber splice point has certain loss and unreliability, and the DTS thermometric is caused negative effect.Another built-in significant disadvantage is, because the residing position of optical fiber in cables manufacturing, is coiled, transports, and the installation and operation stage might be subjected to tension force.And the mechanical strength of optical fiber is very low, can't keep in repair again in case damage.Therefore protection design, manufacturing and the construction to optical fiber all proposed higher requirement.
Except being subjected to outside destroy, the workmanship defective of cable and annex thereof, installation quality defective and ageing of insulation all can cause cable fault.These faults have an insulation degradation usually and produce the process of partial discharge before causing that cable is final and destroying.Detection to partial discharge is an important means of fault monitoring.Optical fiber sensing technology can be used for the detection of partial discharge.As method, can detect ultrasonic wave and other unusual mechanical oscillation that cable local discharge produces by interfering.Need there be the problems referred to above in this equally along arranging detecting optical cable on the cable length direction.And, because hyperacoustic propagation has directivity and decay rapidly, occur in the partial discharge of the same intensity on the same cross section, the detection optical fiber that is arranged in an eccentric side may provide different detection limits because the residing angle of partial discharge position is different, in addition may detect less than.
In addition, statistics shows that cable intermediate joint and cable termination put into operation several years ago at cable system, and its failure rate is far longer than the failure rate of cable body.Fault type had both comprised because the bad connection of the connector of cable conductor or binding post causes overheatedly, had also comprised cable intermediate joint and cable termination because the insulation fault that defective that design, manufacturing and erection stage are introduced or bad point cause.And in above-mentioned optical cable arrangement, detection optical fiber is positioned at the cable insulation outside of earth potential, and the physical dimension of this insulation is all greater than the insulation of cable body, in more situation, optical fiber even have to be arranged in outside the cable metal shielding or cable joint waterproof jacket with bigger physical dimension.At this moment, the position at detection optical fiber place is compared the temperature response of conductor heating and the situation of cable body, not only a little less than but also lag behind.Just inapplicable for the calculating conductor mathematic model of temperature that cable body is set up, the temperature anomaly of cable also is not easy to be detected.Similarly, the local discharge signal that its built-in electrical insulation fault is produced is also decayed comparatively seriously because will penetrate thicker insulation and other sheaths, is difficult for being detected optical fiber and detects.
In the utility model, optical fiber refers to mainly bare fiber that is made of quartz or the bare fiber with coat, and it can not bear, and fractures easily; Optical cable comprises optical fiber and the protection structure that bears and/or radial pressure cushions.Typically, optical cable has plastics or metallic sheath or sheath.
In the utility model, high end finger 35kV and above exchanging or direct voltage comprise high pressure, superhigh pressure and ultra high voltage.
Fig. 6 is the terminal structure schematic diagram of conventional high voltage power cable.This terminal is used in Cable Transformer or overhead wire connects.This terminal has mainly comprised conductor binding post 20, insulation unit 21 and radome 22.Binding post 20 is done by copper, is used for connecting and fixing high-tension cable center conductor 19.The insulation unit is used to prevent the electric field gathering and prevents that external contamination from entering.Radome is a rounded profile, prevents that high pressure from causing the possibility of corona.
Optical fiber or optical cable all are the outsides that is placed on cable insulation in the conventional fiber composite power cable, when cable termination is made, at first optical cable are drawn from cable, respectively electric part are connected with opticator then.
In order to solve the deficiency of prior art, need a kind of cable center conductor inside to have the high voltage power cable of detection optical fiber and supporting with it electric cable accessories, thereby optical fiber can directly detect the conductor temperature of cable, and can detect the ultrasonic signal that cable office puts effectively.And present terminal can't solve the problem of drawing of conductor inner fiber.
