Description
Technical field
The present invention relates to transmission of electricity fitting field more particularly to a kind of ground wire guard systems.
Background technique
One to two ground wire, also known as lightning conducter are usually provided in transmission line of electricity above conducting wire, plays reduction thunder and lightning
Attack the effect of conducting wire directly.In the process of running, it often will appear ground wire line-outage contingency.Since ground wire is in the top of conducting wire, broken string
It is easy the conducting wire of touching lower section, further causes conducting wire short circuit tripping, conducting wire of burning, or even cause conductor cord disconnection.Double loop is very
Once ground wire broken string occurs, the easy multi circuit transmission lines that cause trip the transmission line of electricity set up to multiloop simultaneously, and large area is caused to stop
Electrification.
The reason of wherein most broken string happens at the pendency hanging point of straight line pole, causes ground wire to break through analysis
Predominantly it is stranded in hitch point to be easiest to vibrating fatigue for ground wire.
Transmission line of electricity O&M company common practice is the slightly long ground wire of the timely replacement operation time limit.Ground wire is replaced to need
Crossing frame is set up along the line, and project cost is very high, and multi-circuit lines on the same tower has a power failure for a long time simultaneously, very to power grid and social influence
Greatly.Only because hitch point defect seldom partially occurs and whole ground wire is shortened service life replacement, will cause largely to provide
Produce Value Loss.
Summary of the invention
The main object of the present invention is to provide a kind of ground wire guard system, which aims to solve the problem that ground wire may
Fatigue fracture is led to the problem of to cause multiloop short circuit.
To achieve the above object, a kind of ground wire guard system provided by the invention includes ground wire, and the ground wire passes through pendency
Fitting is hung on steel tower cross-arm, the ground wire guard system further include:
Metal wire cluster, the metal wire cluster are helically wound around the hitch point on the ground wire and close to the ground wire；
Clamping piece, the clamping piece include the clamping head being installed on the steel tower cross-arm and connect with the clamping head
Metal wire, the metal wire connect the metal wire cluster.
Preferably, the arch gap passed through for the metal wire is formed between the metal wire cluster and the ground wire.
Preferably, the clamping head includes substrate and is fixed on the pressing plate on the substrate by threaded fastener, described
The mounting hole for being fixed on the steel tower cross-arm is formed between substrate and pressing plate.
Preferably, the metal wire is coated in isolating shrinkable tube
Preferably, the metal wire cluster is formed by the aluminium alloy wire adhesion of 3~5mm of multiply diameter.
Preferably, the clamping piece and metal wire cluster are conductive material.
In technical solution of the present invention, the distribution line overall structure the characteristics of and due to wind direction etc., conducting wire office
Portion place is easier fatigue broken string occur, and wherein fatigue fracture occurs mainly in ground wire at suspension.Therefore, for these danger
Break region winding metal wire cluster, and metal wire cluster can play reinforcement effect to conducting wire, increase mechanical strength.In addition, clamping piece
It is clamped on steel tower cross-arm, and metal wire cluster is connected by metal wire, even if dangerous section breaks, metal wire can also holds two
Side ground wire avoids falling and hurt sb.'s feelings, and reduces and gives electric power first-aid bring trouble.

Within enclosing.
Referring to attached drawing 1, a kind of ground wire guard system includes ground wire 100, and ground wire 100 hangs on iron by overhanging golden tool 200
On tower cross-arm 300, ground wire guard system further include: metal wire cluster 410, metal wire cluster 410 are helically wound around on ground wire 100 simultaneously
Close to the hitch point of ground wire 100；Clamping piece, clamping piece include the clamping head 420 being installed on steel tower cross-arm and with clamping head 420
The metal wire 430 of connection, metal wire 430 connect metal wire cluster 410.
In technical solution of the present invention, the distribution line overall structure the characteristics of and due to wind direction etc., conducting wire office
Portion place is easier fatigue broken string occur, and wherein fatigue fracture occurs mainly in ground wire at suspension.Therefore, for these danger
Break region winding metal wire cluster 410, and metal wire cluster 410 can play reinforcement effect to ground wire 100, increase mechanical strength.Separately
Outside, clamping piece is clamped on steel tower cross-arm 300, and connects metal wire cluster 410 by metal wire 430, even if dangerous section is broken
Line, metal wire 430 can also hold two sides ground wire, avoid falling and hurt sb.'s feelings, and reduce and give electric power first-aid bring trouble.
Preferably, the arch gap passed through for metal wire 430 is formed between metal wire cluster 410 and ground wire 100.To facilitate gold
Belong to after line 430 passes through the arch gap and being fixed on metal wire cluster 410.Metal wire 430 can form knot or pass through mechanical clasps
Part is fixed on metal wire cluster 410.
Further, clamping head 420 includes substrate and is fixed on the pressing plate on substrate by threaded fastener, substrate and
The mounting hole for being fixed on steel tower cross-arm 300 is formed between pressing plate.Mounting hole is preferably rectangular opening, with steel tower cross-arm 300
Section be adapted.
