Abstract
The utility model relates to a transformer station optical cable terminal leading-down clamping base fastening device which is used for fixing an overhead ground wire composite optical cable in an electric power system transformer station on a steel plate flange. The transformer station optical cable terminal leading-down clamping base fastening device is characterized in that a cable-pressing device an anti-creepage insulator are fixed on a spacing pillar which is fixed on a U-shaped clamping base. A problem of optical cable loosening caused by aging of a rubber gasket is eliminated, discharge and strand breakage are ensured not to be performed by a leading-down optical cable in the transformer station on a rod body framework and safe operation rate of the leading-down optical cable in the transformer station is enhanced so that the transformer station optical cable terminal leading-down clamping base fastening device is convenient to use and safe and reliable in operation, and thus power supply enterprise operation and maintenance cost are reduced.
Description
Technical field
the utility model relates to and a kind ofly draws lower deck fastener for transformer station's optical fiber cable termination that aerial earth wire composite cable in power system transformer substation is fixed on steel plate flange.
Background technology
at present, domestic power system transformer substation aerial earth wire composite cable is continuity circuit lightning conducter erection mode, enter after the door type framework top lightning conducter terminal shaft tower tension-resistant porcelain bottle in transformer station, under drawing again, to door type framework one side lever body, fix, and to downward-extension, after several point of fixity, arrive equipment place.Lightning conducter terminal pole bottom is to adopt steel plate flange technique to be connected with door type truss bar top, flange has limit to prolong, optical cable draws after lower fixing, time one is long, there will be looseningly, can receive tactilely with steel plate flange limit, produce disconnected strand of galvanic corrosion, cause substantial equipment defect hidden danger to lightguide cable link, threaten the safe operation of optical cable.
Summary of the invention
goal of the invention of the present utility model, will solve exactly aerial earth wire composite cable draws lower time and flange and receives tactile, the galvanic corrosion strand broking occurring, provide the spacing under a kind of can drawing according to the lightning-arrest body of rod and aerial earth wire composite cable on each transformer station's door type truss bar to carry out field conduct adjustment and installation, can stop the aerial earth wire composite cable terminal of equipment deficiency hidden danger and draw lower deck fastener.Technical solution of the present invention is such; A kind of transformer station optical fiber cable termination draws lower deck fastener, it is characterized in that pressing cable device and anti-tracking insulator to be fixed on spacing pillar, and spacing pillar is fixed on U-shaped deck.When use, U-shaped deck is fixed on steel plate flange, optical cable is fixed on and presses the steady job that just can complete optical cable on cable device.Use the beneficial effects of the utility model are; U-shaped deck can very convenient and firmly be fixed on steel plate flange, presses cable device by very convenient optical cable and firmly fix, to be difficult for deviating from.
anti-tracking insulator on spacing pillar makes optical cable and steel plate flange produce certain distance, and the electric discharge of optical cable is deadened by anti-tracking insulator and the thigh phenomenon that is difficult to occur break.Stop the aging optical cable that causes of former rubber blanket and deviate from problem.Ensured to draw in transformer station lower optical cable body of rod framework is not discharged, constantly strand, improved the safe operation rate of drawing lower optical cable in transformer station, it is easy to use, safe and reliable to operation, has reduced power supply enterprise's O&M cost.
Brief description of the drawings
accompanying drawing 1 is schematic diagram of the present utility model.
Embodiment
in Fig. 1, pressure cable device 1 and the anti-tracking insulator 3 made with metal material are fixed on spacing pillar 4. and press on cable device 1 and set bolt 2 is installed and presses cable hinge 7, spacing pillar 4 is connected and fixed with U-shaped deck 5, and horizontal adjusting bolt 8 and deck fastening bolt 6 are installed on U-shaped deck 5.When use, U-shaped deck 5 is stuck on steel plate flange, U-shaped deck 5 is fastening by horizontal adjusting bolt 8 and deck fastening bolt 6, firmly be fixed on steel plate flange, the aerial earth wire composite cable drawing under needs is fixed on and is pressed on cable device 1, press cable device 1 by set bolt 2 and press cable hinge 7, aerial earth wire composite cable is firmly fixed.
