Abstract
The invention relates to an anti-ice coating optical fiber composite overhead earth wire based on optical fiber temperature measurement, which comprises an aluminum alloy wire, an aluminum-clad steel wire, an optical unit and an aluminum pipe. The optical unit is arranged in the aluminum pipe; and the aluminum pipe and the aluminum-clad steel wire are arranged on the inner side of the aluminum alloy wire. The overhead earth wire is characterized in that an anti-ice coating conducting wire arranged with the aluminum pipe and the aluminum-clad steel wire side by side is arranged on the inner side of the aluminum alloy wire; the anti-ice coating conducting wire also can be arranged in the cavity of the aluminum pipe; an insulating layer is arranged outside the anti-ice coating conducting wire; a temperature measurement fiber core is arranged in the aluminum pipe; and both the temperature measurement fiber core and the anti-ice coating conducting wire are connected with a temperature measurement heating control terminal. The anti-ice coating optical fiber composite overhead earth wire based on the optical fiber temperature measurement can basically solve OPGW ice coating and a series of problems such as broken lines, tower falling- down, tripping and the like caused by the OPGW ice coating, has strong applicability, can be used for various routines like extra high voltage, ultra high voltage, 220KV and below and maintain intellectualization, and not only can be controlled automatically through procedures, but also can accurately position the troubles.
Description
Technical field
The present invention relates to a kind of anti-ice cover Optical Fiber composite overhead Ground Wire based on optical fiber temperature-measurement.
Background technology
OPGW (optical fiber composite overhead ground wire) is the Optical Fiber composite overhead Ground Wire that is used for electric system, its have safe and reliable, be not subject to outside destroy, do not need to establish in addition advantages such as corridor, space.But under ice and snow disaster influence, often much all be that ground wire or OPGW interrupt earlier, cause wire electrical discharge, line tripping again, perhaps iron tower is subjected to unbalanced tensile force and causes that tower head fractures or fall tower.As everyone knows, lead has electric current to flow through under normal operating condition can produce certain heat, and OPGW is ground connection and belt current not under normal operating condition, does not produce heat, and this makes OPGW run into the easy icing of sleet diastrous weather.From the actual conditions of ice damage, the thickness of OPGW and ground wire icing obviously be thicker than lead and the ice-melt time more late, the icing of OPGW can cause pernicious consequence to power circuit.For example, from disaster-stricken 500KV in 2008 and the 220KV circuit situation of falling the tower, majority is earlier disconnected ground wire or OPGW, the broken string back is owing to tension imbalance, and tower head all can have tangible inclination distortion, and the serious tower head that caused fractures, and OPGW or ground wire broken string, the line tripping that causes has a power failure, and the wire icing aggravation then can make fault worsen, repair difficulty and increase.
Summary of the invention
Purpose of the present invention just provides a kind of anti-ice cover Optical Fiber composite overhead Ground Wire based on optical fiber temperature-measurement that can be applicable to harsh climate.
