Description
Technical field
A kind of soft graphite bonded earth electrode fast splicing device, belongs to power system transmission line grounding apparatus field.
Background technology
Since electric system grounded screen is started using various problems, existing metallic ground material existing for metallic ground body
Gradually seek substitute, graphite starts gradually to be received by electric system as a kind of natural non-metallic conducting material.From
Since 2012, with graphite be main conductive material earthing material of new generation --- the compound earthing material of soft graphite start by
Gradually in electric system especially transmission line tower grounding network large area popularization and application, thoroughly solve the corrosion of grounded screen
Problem provides new technical thought and solution for the reliable ground of electric system.
Often exist since grounded screen is often formed by a plurality of grounding body according to certain combination of shapes, in grounded screen more
The connecting node of a grounding body.Traditional metallic ground material is frequently with electric welding, gas welding or puts heat weldable connection method.Tradition
The advantages of welding method, is：Connection method is that chemistry welds, and is connected firmly；Disadvantage is：Soldering appliance is heavy, is not easy to family
Outer construction, operating expenses are high, in addition, pad is often the centrostigma of electrochemical corrosion so that often formed at pad
Primary battery is learned, the corrosion of grounding body is accelerated.
Compared to the welding manner of conventional metals grounding body, the compound earthing material of soft graphite is non-metal grounding material,
It chemical can not weld, physics can only be used to crimp mode.The compound earthing material of previous soft graphite connects part and deposits when in use
In problems with：（1）It is inconvenient to connect part construction, need grounding body pass through connect part and cannot from any point of grounded screen into
Row connection.（2）It is low to connect part bonding strength, often uses Bolt Tightening Force dead earth body, is easy to happen loosening.（3）It is only suitable
For the connection between the compound earthing material of soft graphite, it is not applied for the compound earthing material of soft graphite and metallic ground body
Connection, narrow application range.（4）The cost for connecting part is high, and the construction cost of single point of attachment is high.
Therefore, it when practical transmission line tower grounding network is constructed using the compound earthing material of soft graphite, needs to use
It is connected firmly, connecting part easy to use.Connect part bonding strength be directly related to entire grounded screen grounding resistance and
Long Service Life.Therefore, it designs and Implements to have and is reliably connected performance, convenient, strong applicability, low cost the flexible stone of construction
Black bonded earth electrode, which connects part, has engineering significance.
