Abstract

The utility model relates to an anti-ice coating composite optical fiber overhead earth wire based on optical fiber temperature measurement. The overhead earth wire 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; the aluminum pipe and the aluminum-clad steel wire are arranged on the inner side of the aluminum alloy wire; the anti-ice coating composite optical fiber overhead earth wire is characterized in that an anti-ice coating lead 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 and also can be arranged in the inner cavity of the aluminum pipe; an insulating layer is arranged outside the anti-ice coating lead wire; a temperature measurement fiber core is arranged in the aluminum pipe; and the temperature measurement fiber core and the anti-ice coating lead wire are connected with a temperature measuring and heating control terminal. The anti-ice coating composite optical fiber overhead earth wire based on the optical fiber temperature measurement can basically solve OPGW ice coating and a series of problems such as wire broken, tower falling down, tripping and the like caused by the OPGW ice coating, has the advantages of strong applicability and intelligence maintenance, and can be used for various lines of extra high voltage, ultra high voltage, 220 KV and above, carry out automatic control through the procedure, and accurately positioning for faults.

Description

Anti-ice cover Optical Fiber composite overhead Ground Wire based on optical fiber temperature-measurement

Technical field

The utility model 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 power 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

The purpose of this utility model 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.

Anti-ice cover Optical Fiber composite overhead Ground Wire based on optical fiber temperature-measurement of the present utility model, comprise aluminium alloy wire, aluminium-clad steel wire, light unit and aluminum pipe, the light unit is in aluminum pipe, aluminum pipe and aluminium-clad steel wire are located at the aluminium alloy wire inboard, be characterized in that the aluminium alloy wire inboard is provided with an anti-ice cover lead that is arranged side by side with aluminum pipe and aluminium-clad steel wire, the anti-ice cover lead also can be arranged in the aluminum pipe inner chamber, anti-ice cover lead peripheral hardware insulating barrier, be provided with the thermometric fibre core in the aluminum pipe, thermometric fibre core and anti-ice cover lead all link to each other with thermometric heating control terminal.

Anti-ice cover Optical Fiber composite overhead Ground Wire based on optical fiber temperature-measurement of the present utility model compared with prior art has the following advantages:

1, can fundamentally solve OPGW icing and the broken string that causes by the OPGW icing, a series of problems such as tower, tripping operation of falling;

2, need not change on a large scale existing design standard;

3, applicability is strong, can be used for ultra high voltage, superhigh pressure, 220KV and following various circuits;

4, safeguard intellectuality, can control automatically, also can accurately locate fault by program.
