Description
Technical field
The present invention relates to a kind of Optical Fiber composite overhead Ground Wire (OPGW) reliable ground device, is a kind of for reliably insulation after line ice coating, direct current list insulator ice-melt grounding switch.
Background technology
China is one of comparatively serious country of powerline ice-covering.The harm of line ice coating is mainly manifested in the aspects such as the broken string of falling tower, insulator arc-over, conductor galloping, tripping operation, even may cause electrical network paralysis when serious, and national product and people's lives are caused to heavy losses.
But for a long time because technical merit is limited, OPGW optical cable can not insulate completely and between steel tower, therefore be difficult to realize ice-melt.At present still adopt the mode by tower ground connection, after icing, cause overhead ground wire generation slippage, cause line tripping to stop transport, and the serious time broken string of ice and snow, the situation of the faults such as tower of falling, the safe operation of electrical network can not get reliable guarantee.
Summary of the invention
The object of the invention is provides a kind of single insulator ice-melt grounding switch for above-mentioned weak point, it is the grounding switch for ice-melt, ensureing under the prerequisite of OPGW properties of optical fiber cable, utilize the closure state of grounding switch, realize the single-point grounding mode of circuit, thereby reduce the induced current loss that OPGW produces by tower ground connection.In the time being struck by lightning, by disconnecting link, large electric current is directed to shaft tower, play lightning protection function.Utilizing the open mode of grounding switch, make whole piece circuit in all insulation state, by transmission current or adopt short circuit current, is heat energy by electric energy conversion, reaches ice-melt heat balance and realizes ice-melt.
The present invention takes following technical scheme to realize:
A kind of single insulator ice-melt grounding switch, comprises train wheel bridge, upper fixture, device clamp, insulator, disconnecting link, base plate, connection bearing, C type geometrical clamp and fishbolt;
On one end of base plate, insulator is installed, connection bearing is installed on the other end of base plate, top at insulator is provided with train wheel bridge, device clamp is housed on train wheel bridge, on the top of train wheel bridge, fixture is housed, disconnecting link one end is movably hinged with being connected bearing by pivot pin, and the disconnecting link other end and upper fixture are connected, C type geometrical clamp is fixedly mounted on base plate, on C type geometrical clamp, fishbolt is installed.
Further, described C type geometrical clamp is at least provided with 2.
Further, in described insulator, insulation mandrel is housed.
When list insulator ice-melt grounding switch of the present invention uses, it is fixed on iron tower main material by C type geometrical clamp, fishbolt, and OPGW optical cable is connected with single insulator ice-melt grounding switch by device clamp.Conventionally ensureing, under the prerequisite of OPGW properties of optical fiber cable, to utilize the closure state of disconnecting link to realize the single-point grounding mode of circuit, thereby reducing the induced current loss that OPGW produces by tower ground connection.In the time being struck by lightning, by disconnecting link, large electric current is directed to steel tower, play lightning protection function.In the time that electrical network has suffered serious line ice coating disaster, after being OPGW optical cable (Optical Fiber composite overhead Ground Wire) icing, utilize the open mode of disconnecting link, make whole piece circuit in all insulation state, by transmission current or employing short circuit current, be heat energy by electric energy conversion, OPGW optical cable (Optical Fiber composite overhead Ground Wire) bulk temperature is raise, melt the surperficial icing of OPGW optical cable (Optical Fiber composite overhead Ground Wire), reach ice-melt heat balance and realize ice-melt.
List insulator ice-melt grounding switch modern design of the present invention, simple in structure, conduct electricity very well, decay resistance is superior, operation, easy to maintenance.
