Description
Technical field
The utility model relates to a kind of electric industry safeguard, relates in particular to a kind of shaft tower shunting backguy and copper ground structure.
Background technology
Shaft tower is one of basic equipment in the overhead distribution, because shaft tower is higher, therefore is very easy to cause thunderbolt.And thunderbolt is a main cause damaging power supply unit, usually adopts the mode of insulator string, overhead ground wire and the combination of wire jumper insulator string to carry out lightning protection in the shaft tower of the prior art.But at mountain area microclimate district transmission line, weather is complicated, and condition of power supply is poor, even therefore done many lightning protection measuress in the prior art, but the lock rate of being struck by lightning is also high.To this, we need to improve existing tower structure and find a kind of more effective lightning protection structure, and need to reduce the cost at this as far as possible.
The utility model content
The purpose of this utility model provides shaft tower shunting backguy and copper ground structure, and shaft tower shunting backguy and the integrated application of copper ground connection can effectively be lowered tripping rate with lightning strike, and cost is low, and mounting condition requires low, especially is fit to be installed in the meteorological complicated places such as mountain area.
For reaching described effect, the shunting backguy of the utility model shaft tower and copper ground structure, comprise the ground wire cross-arm that is installed in the shaft tower top and be embedded in shaft tower a plurality of copper earthing device on every side, described ground wire cross-arm is provided with a plurality of backguy hanging wires hole, be fixed with a good conductor shunting backguy in each backguy hanging wire hole, the other end of described good conductor shunting backguy is connected to a copper earthing device, is the angle of 55-75 degree between described good conductor shunting backguy and the ground.
Preferably, described copper earthing device quantity is 2, and described ground wire cross-arm is provided with 4 backguy hanging wire holes, and the both sides that are located at the ground wire cross-arm are divided in described backguy hanging wire hole, and many good conductor shunting backguys of every side be arranged in parallel, and are 60 degree angles with ground.Such structure is used for the less occasion that a large amount of copper earthing device can't be set in place.Because the place is less, so the copper earthing device is nearer apart from shaft tower, many good conductor shunting backguys be arranged in parallel and are 60 degree angles with ground and can reach optimum efficiency, shunt fast when being subject to being struck by lightning, and also are difficult at ordinary times damaging because of self tension force.
Preferably, described copper earthing device quantity is 4, and described ground wire cross-arm is provided with 16 backguy hanging wire holes, does not mutually contact between 16 good conductor shunting backguys between backguy hanging wire hole and the copper earthing device, and is 55 degree angles with ground.Such structure is applicable to the place broad, perhaps lightning protection is required very high occasion.Good conductor shunting backguy and ground are the copper earthing device layout that 55 degree angles are conducive to ground.
Preferably, described copper earthing device adopts the copper-plated ground rod, namely is that copper earthing device heart is rigid steel, and the steel skin is coated with layer of copper, and described copper-plated ground rod length is not less than 1.5 meters.Because it is durable in use that the copper earthing device needs, and need to minimize cost, therefore such structure is the most practical, is fit to large-scale production.
Preferably, cover has the erosion resisting insulation layer outside the described good conductor shunting backguy.Such structure guarantees to be arranged on open-air good conductor shunting backguy long enough in useful life.
Owing to adopted described technical scheme, the structure of shaft tower shunting backguy and copper ground connection can not only the Effective Raise shunting effect, reduce impedance, reduce shaft tower and wire shielding trip-out rate, can also reducing ground resistance, reduce the counterattack trip-out rate of shaft tower and wire, copper ground connection has the reliability that can effectively improve grounding system.
