Abstract
The utility model relates to a cable, and especially relates to an optical fiber composite copper wire shielding type high-voltage and direct-current crosslinked cable having a nominal voltage of 30kV-500kV. The optical fiber composite copper wire shielding type high-voltage and direct-current crosslinked cable having a nominal voltage of 30kV-500kV comprises a conductor and an insulating layer. The optical fiber composite copper wire shielding type high-voltage and direct-current crosslinked cable is characterized in that the insulating layer is sleeved with a semiconductive buffer strip or a semiconductive buffer and water-blocking strip, the semiconductive buffer strip or the semiconductive buffer and water-blocking strip is sleeved with a copper wire shielding layer, an aluminium-plastic composite strip is wrapped around the copper wire shielding layer, and a temperature measuring optical cable is embedded into the aluminium-plastic composite strip. The optical fiber composite copper wire shielding type high-voltage and direct-current crosslinked cable of the utility model has advantages of cable operation maintenance free, convenient cable laying, no drop restriction, good operation reliability, etc., and has the on-line temperature measuring function.
Description
Technical field
The utility model relates to a kind of cable, especially relates to a kind of rated voltage 30kV ~ compound brass wire shielding high voltage direct current of 500kV optical fiber crosslinked cable.
Background technology
As everyone knows, HVDC Transmission Technology is to adopt voltage source converter and PWM technology based on cut-offfing the type device to carry out direct current transportation.The very applicable regenerative resource of this technology is grid-connected, the fields such as distributed power generation is grid-connected, isolated island power transmission, urban distribution network power supply, Asynchronous Communication Power System Interconnection.30kV ~ 500kV high voltage direct current cable traditional structure is to adopt oil-impregnated paper insulation structure or oil-filled paper insulation structure, and adopts plumbous cover as watertight composition, without the temperature measurement on-line function.
The defect of prior art and deficiency have following 4 points.1, oil-impregnated paper insulation direct current cables inside has a large amount of fluid insulation oil to exist, high to the running environment requirement, must carry out fire prevention and processing; 2, in running, oil pressure varies with temperature and changes, and must monitor in real time; 3, due to the existence of oil pressure, cable is limited by drop.4. without the temperature measurement on-line function, operational reliability is poor.
Summary of the invention
The utility model is mainly for the existing above-mentioned technical problem of prior art, the rated voltage 30kV that provide that the operation of a kind of cable is non-maintaining, cable laying convenient, be not subject to the drop restriction, possess the temperature measurement on-line function, operational reliability the is high ~ compound brass wire shielding high voltage direct current of 500kV optical fiber crosslinked cable.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of rated voltage 30kV ~ compound brass wire shielding high voltage direct current of 500kV optical fiber crosslinked cable, comprise conductor and insulating barrier, it is characterized in that described insulating barrier is arranged with Semi-conductive buffer band or semi-conductive buffer water-blocking band outward, described Semi-conductive buffer band or semi-conductive buffer water-blocking band are arranged with shielding layer of copper wires outward, described shielding layer of copper wires is surrounded with aluminium-plastic tape outward, also is embedded with temperature measuring optical cable in described aluminium-plastic tape.Rated voltage 30kV ~ compound brass wire shielding the high voltage direct current of 500kV optical fiber crosslinked cable is to using the insulation of crosslinked polyethylene (XLPE) as cable, temperature-measuring optical fiber is placed on to the insulated wire cores surface, can on-line monitoring cable insulation temperature, and then whether operating temperature that can monitoring cable exceed standard, improved the security reliability of cable line.
As preferably, described aluminium-plastic tape is arranged with oversheath outward.
Therefore, the utlity model has that cable operation is non-maintaining, cable laying convenient, be not subject to the drop restriction, possess temperature measurement on-line function, operational reliability high.
The accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
As shown in Figure of description 1, a kind of rated voltage 30kV ~ compound brass wire shielding high voltage direct current of 500kV optical fiber crosslinked cable, comprise conductor 1 and insulating barrier 2, the outer semi-conductive buffer water-blocking band 3 that is arranged with of insulating barrier 2, the outer shielding layer of copper wires 4 that is arranged with of Semi-conductive buffer band or semi-conductive buffer water-blocking band 3, shielding layer of copper wires 4 is outer is surrounded with aluminium-plastic tape 5, also is embedded with temperature measuring optical cable 6 in aluminium-plastic tape 5.The outer oversheath 7 that is arranged with of aluminium-plastic tape 5.
The utility model efficiently solves XLPE problems with space charge under the direct current field intensity, adopt special construction to adapt to special employing XLPE as high-voltage DC cable insulating simultaneously, replace oil-paper and oil-filled paper insulated cable, the cable operation can be non-maintaining, and cable laying is convenient, not limited by drop, key is to have possessed the temperature measurement on-line function, operating temperature that can the on-line monitoring cable insulation, can prevent the cable line overlond running, and operational reliability is high.
Should be understood that this embodiment only is not used in restriction scope of the present utility model for the utility model is described.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
