Description
Technical field
The invention belongs to overhead power transmission line pole tower grounded screen Lightning protection field, particularly relate to a kind of graphite and be combined
Grounding body speed connects cartridge type and continues part and application thereof.
Background technology
Power system longtime running experience have shown that, transmission line lightning stroke trip accident causes transmission line of electricity stoppage in transit accident
Principal element.Although common lightning arrester such as lightning conducter, spark gap etc. play preferable lightning protection effect, but invest excessive,
Later maintenance work is heavy.From the point of view of actual lightning protection effect, the earth resistance reducing transmission line tower grounding network is warp the most
Help effective transmission line of electricity lightning protection means.The most existing tower grounding net still more uses metallic ground material, metallic ground material
The material distinct issues the most that are in operation are exactly etching problem, and common steel, galvanized steel even copper cover the steel capital sending out in various degree
Raw corrosion phenomenon, the area of some seriously corrodeds will be changed grounded screen every 5 to eight years, transport to transmission line of electricity safety and stability
Row causes a hidden trouble, and transmission line tower grounding network investment is multiplied with maintenance cost.
In recent years, soft graphite was combined earthing material as a kind of emerging non-metal grounding material, and it effectively prevent
The etching problem of metallic ground material, and in transmission line tower grounding network, obtain popularization and application progressively.But as one
Planting novel earthing material, soft graphite is combined earthing material and also runs into some problems, such as soft graphite in practice of construction
Compound earthing material is non-metal grounding material, and the connection in its cross point cannot use the conventional connection such as electric welding, gas welding, heat release weldering
Means are attached, and limit it to a certain extent and promote the use of.
Owing to the junction point of grounded screen is easily to occur the fracture key position with poor electric contact that comes off in grounded screen, adopt
With rationally, easily fastening means be solve soft graphite be combined the cross-coupled key point of earthing material.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction graphite bonded earth electrode speed easily of constructing to connect cartridge type and continue part
And application, can be used for soft graphite and be combined the interconnection of earthing material non-solder mode.
For reaching above-mentioned purpose, the present invention adopts the following technical scheme that
A kind of graphite bonded earth electrode speed connects cartridge type and continues part, including:
The upper semi-circle cylinder matched and lower half circle cylinder, and left annular fixing member and right annular fixing member；
Upper semi-circle cylinder and lower half circle cylinder all with axially through groove, are used for placing graphite bonded earth electrode axially through groove；
Upper semi-circle cylinder and lower half circle cylinder two ends outer surface are equipped with external screw thread；In the dual-side of upper semi-circle cylinder and lower half circle cylinder
Edge is the most equidistantly provided with some grooves；
Left annular fixing member and right annular fixing member inwall are equipped with female thread, radially offer two on the left of left annular fixing member
Individual draw-in groove, the most also offers two draw-in grooves on the right side of right annular fixing member；
Upper semi-circle cylinder is placed on lower half circle cylinder and constitutes an integral barrel body, and left annular fixing member and right annular fixing member are respectively
It is placed on left end and the right-hand member of described integral barrel body.
It is dimensioned such that graphite bonded earth electrode can just be inserted axially through groove.Axially through groove by some grades between
Concavo-convex non-smooth structure is obtained, so, when graphite bonded earth electrode is inserted, on the one hand, when graphite is combined ground connection away from groove
When body pressurized deforms upon, just can fill equidistant groove, beneficially graphite bonded earth electrode be positioned over smoothly axially through
In groove；On the other hand, equidistant groove can significantly increase graphite bonded earth electrode and the frictional force axially through groove inwall so that
The tensile strength of part of continuing greatly increases.
For ease of using tools to connect annular fixing member and semicylindrical body, at left annular fixing member and right annular fixing member
On draw-in groove is set.
The each parts of the present invention preferably use material corrosion-resistant, age inhibiting to prepare, such as the synthesis such as epoxy resin, fiberglass material
Expect or galvanized steel, copper cover the corrosion-resistant metal materials such as steel.
The present invention is applicable to the connection of soft graphite bonded earth electrode, such as, can be used for tower grounding downlead and level
The connection between connection, horizontal grounding objects and Grounding Grids between the connection of grounded screen, horizontal grounding objects.During use, the present invention
The part length that continues is to be advisable not less than 6 times of wall scroll grounding body diameter.
Compared to the prior art, the invention have the advantages that and beneficial effect:
(1) present invention is mainly made up of two semicylindrical body and two annular fixing members, and semicylindrical body inner chamber is compound with graphite to be connect
Terrain bonding strength is big, and closely, contact resistance is little for the electrical contact of graphite bonded earth electrode.
(2) present configuration is simple, constructs convenient, and easily transport is carried, it is not necessary to the Heavy-duty Tools such as welding, and motility is high, becomes
This is cheap, can realize batch production, and future in engineering applications is wide.
(3) present invention is applicable to the connection between tower grounding downlead and the connection of horizontal grounding net, horizontal grounding objects, water
Flush the junction point between terrain and Grounding Grids, can effectively strengthen graphite and be combined the bonding strength of grounded screen junction point, and suitable
Wide by property.
(4) each parts of the present invention use material corrosion-resistant, age inhibiting to prepare, reusable edible.
