Description
Technical field
The utility model is related to field of transmission equipment, and in particular to a kind of extra-high voltage lightning conducter anti-off device.
Background technology
Generally being set up in transmission line of electricity in the top of wire has one to two lightning conducter, also known as ground wire, plays reduction thunder and lightning
Attack the effect of wire directly.In the process of running, lightning conducter line-outage contingency often occurs.Because lightning conducter is in the top of wire,
Wire below the easy touching of broken string, further causes wire short circuit tripping operation, wire of burning, or even cause conductor cord disconnection.Double back
The road transmission line of electricity that even multiloop is set up easily triggers multi circuit transmission lines to trip simultaneously once occurring lightning conducter broken string, causes big
Area power outage.
Wherein most broken string situation occurs at the pendency hanging point of straight line pole, and the original that lightning conducter breaks is caused through analysis
Because being mainly:1st, mechanical aspects：It is stranded that lightning conducter is easiest to vibrating fatigue in hitch point.2nd, the Suspension Technique side of current lightning conducter
The mechanically stressed problem of solution is overweighted, it is inconsiderate for being conductively connected.The contact resistance of lightning conducter and suspension clamp is larger, online
When road is struck by lightning or is short-circuit, moment tens to the electric current of kiloamperes up to a hundred fuses lightning conducter.
Through understanding, also for above-mentioned problem integrate the technical scheme of solution in existing technology.It is defeated
Electric line O＆M company common practice is timely to change the operation time limit slightly long lightning conducter.Changing lightning conducter needs to take along
If crossing frame, construction costs is very high, multi-circuit lines on the same tower has a power failure for a long time simultaneously, very big to power network and social influence.Only
Merely due to the few of hitch point defect partly occurs and overall lightning conducter is shortened service life and changed, a large amount of assets valencys will be caused
Value loss.
Utility model content
The utility model aims to provide a kind of extra-high voltage lightning conducter anti-off device, and this is mounted directly on the basis of available circuit
Device, on the one hand can be that good conductive channel is provided between lightning conducter and shaft tower, it is to avoid lightning current and earth short circuit current are molten
Disconnected lightning conducter；On the other hand mechanical strength can be reinforced there is provided breaking line preventive guarantee close at suspension clamp to lightning conducter, reduction is lightning-arrest
The O＆M cost of line.
To reach above-mentioned purpose, the utility model proposes technical scheme it is as follows：
Extra-high voltage lightning conducter anti-off device, between cross arm of tower and lightning conducter, including wire breakage preventing device, two it is pre-
Hank knotting, shunt conductor；The two ends of wire breakage preventing device are all connected with a preformed armor rods, and one end of shunt conductor is connected to wire breakage preventing device
On；Wire breakage preventing device is located at the lower section of cross arm of tower, the lightning conducter of the free ends of two preformed armor rodses respectively with cross arm of tower both sides
Connection, wire breakage preventing device and lightning conducter turned in parallel；The free end of shunt conductor is connected with cross arm of tower.
As the improvement of scheme one, two preformed armor rodses are connected and turned on inside wire breakage preventing device.
As the improvement of scheme one, preformed armor rods is connected with lightning conducter by way of winding.
As the improvement of scheme one, shunt conductor is connected on cross arm of tower by shunting wire clamp.
As the improvement of scheme one, the material of preformed armor rods and shunt conductor is aluminium alloy.
As the improvement of scheme one, the material of wire breakage preventing device is aluminium alloy.
The utility model has the advantages that：
1st, using preformed armor rods technology, meet water conservancy diversion and reinforce double effect.
2nd, shunt conductor causes the one part of current on lightning conducter to be flowed directly into through preformed armor rods, shunt conductor and shunting wire clamp
Cross arm of tower, it is to avoid short circuit blows lightning conducter by immediate current when being struck by lightning is excessive.
3rd, the present apparatus is convenient adjusts and the shunt conductor length in wire clamp, is flexibly directed to the different turriforms in extra high voltage line
The problem of lightning conducter is different from the distance of shaft tower gold utensil.
The 4th, the lightning conducter wire breakage preventing device is installed very convenient, does not change original hardware fitting structure, and saving every year may be used
Substantial amounts of maintenance cost is saved, social effect is great.
