Definitions

  • the present invention relates to cables, and more particularly to a high voltage power cable in which a probe fiber is disposed within a cable. Background technique
  • the power sector needs to conduct on-line monitoring.
  • the main contents of online monitoring include load monitoring and fault monitoring.
  • Cable load capacity constraints are primarily derived from the allowable operating temperature limits for cable and cable accessory manufacturing materials.
  • the temperature of the cable conductor that is, the temperature of the XLPE adjacent to the conductor, is usually not specified to exceed 85 ° C or 90 ° C.
  • the load capacity is designed primarily in accordance with the conductor temperature limits.
  • the load capacity of cable systems is usually designed in accordance with IEC60287 and IEC853 standards. These standards assume that the load current is constant or varies substantially according to a daily load curve pattern and assumes that ambient environmental conditions are determined.
  • the ambient conditions of the actual running cable system are complex, and its state may migrate, with a high degree of uncertainty. Therefore, it is impossible to reliably determine the highest temperature of the cable without detecting the temperature distribution of the entire cable.
  • the highest point of cable temperature is also the de facto load bottleneck.
  • a more complicated reality is that the position of the bottleneck point on the same cable changes, and multiple bottlenecks may occur in the same cable over a period of time.
  • the online load monitoring of the cable usually adopts the method of distributed temperature sensor (DTS).
  • DTS distributed temperature sensor
  • the technology can detect a temperature distribution of several kilometers to several tens of kilometers of fiber, and the sampling point distance can reach 1 to 2 meters.
  • the axial temperature distribution of the cable can be obtained. It is generally believed that since the conductor of the high voltage cable is at a high voltage potential, it is wrapped by an insulating layer that is not damaged by integrity, and the optical fiber cannot be placed on or in the conductor and drawn out to the outside of the ground potential. Therefore, it is not feasible to directly measure the conductor temperature using DTS technology.
  • the optical cable containing the temperature measuring fiber is arranged on the surface of the cable;
  • the temperature measuring fiber or fiber optic cable is added to a layer or a layer outside the cable insulation layer, typically outside the semiconductor insulation shield and in the metal sleeve.
  • Korean Patent Publication No. 2003-45864 discloses a system for setting a temperature measuring fiber in a cable for calculating the temperature of an underground power cable conductor.
  • the external temperature measuring fiber can be used to fix the cable to the surface of the cable by manually tying or bonding the cable in the cable tunnel and the direct buried cable in front of the backfill.
  • the cable is usually pulled into the pipe after the cable is piped.
  • the cable is unlikely to be in close contact with the cable surface as in the above case, some of the cables may be in contact with the cable surface, and some may not be in contact with the cable and suspended in the medium in the tube. This will introduce the model into uncertain factors, resulting in larger calculation errors.

Between the layer and the sheath, it is built-in. In the built-in method, the cable is very consistently located in a layer outside the cable insulation, which solves the above-mentioned external problem, but must deal with the problem of the connection of the fiber at the cable connector, which complicates the cable connector installation process. Usually use a jumper The optical cable, two welding points, are respectively welded to the optical fiber taps of the two cables.
  • the number of fusion points on the temperature measuring fiber is at least twice the number of cable joints.
  • the number of fiber splices may be too large.
  • the fiber fusion splice has a certain loss and unreliability, which has a negative impact on DTS temperature measurement.
  • Another significant disadvantage of the built-in type is that it is subject to tension during the manufacturing, coiling, transport, installation, and operation phases of the cable due to the location of the fiber.
  • the mechanical strength of the fiber is very low and cannot be repaired once it is damaged. Therefore, high requirements are placed on the design, manufacture and construction of optical fiber protection.
  • Optical fiber sensing technology can be used for the detection of partial discharges, such as ultrasonic waves and other abnormal mechanical vibrations generated by partial discharge of cables. This requires the placement of the probe cable along the length of the cable, as well as the problems associated with the placement of the cable described above.
  • the propagation of the ultrasonic waves is directional and rapidly decays, partial discharges of the same intensity occur on the same cross section, and the detection fibers disposed on the eccentric side may give different detection amounts due to different angles of the partial discharge positions. , may not even detect it.
  • the cable joints and cable terminals have a failure rate far greater than the failure rate of the cable body in the years before the cable system was put into operation.
  • Types of failure include both overheating due to poor connections of the cable conductors or the poor connection of the terminals, as well as insulation faults caused by defects or defective points introduced in the cable intermediate joints and cable terminations during the design, manufacturing and installation phases.
