Abstract
The utility model discloses a long-service life grounding net of a high-voltage cable. A net rack is provided with a conductive outgoing line and a conductive earth electrode; the net rack is connected by a ring-shaped edge frame and a grid-shaped middle frame; the ring-shaped edge frame is surrounded and connected by a copper strip; the interrupted head of the ring-shaped edge frame is inserted into a pipe joint and is fixed in a welding way; the grid-shaped middle frame is crosswise connected by a copper strip; the interrupted head of the intersection of the copper strip is inserted into the pipe joint and is fixed in a welding way; and the grid-shaped middle frame and the ring-shaped edge frame are inserted with each other by the pipe joint and are fixed in a welding way. The cross section of the copper strip is circular or quadrate. The long-service life grounding net of the high-voltage cable is made from the copper strip, thereby leading the service life to reach 30-60 years, completely meeting the requirement of the operating time of a converting station, greatly guaranteeing the safe and reliable operation of the power grid, and achieving the maintenance-free requirement.
Description
One, technical field: the utility model relates to a kind of cable grounding net, particularly relates to a kind of high-tension cable long-life ground network.
Two. background technology: along with rapid economy development, people more and more pay attention to the living environment of self, the application of various electrical equipment is more and more wider, thereby network load increases year by year, in addition, in order to improve the degree of beautifying in city, the overhead transmission line in city is progressively replaced by underground cable, forms concealed wire and arranges.In order to guarantee cable running safety; avoid harm that cable is struck by lightning and the people's life safety in the protection circuit zone; high-tension cable all will be provided with earthing device; but in the operation maintenance of cable, find; when the high-tension cable in the bustling downtown area that is laid in is carried out regular ground connection excavation and measures junction resistance; because it is many to examine the government department of agreeing excavation; the time of examining is long; and digging process to influence the city attractive in appearance; also may cause road traffic to block; the feasible defective that can not in time find ground network; threaten for the safe operation of electrical network; while is also caused the certain social economic loss, therefore improves the useful life of ground network and reach non-maintaining to be of great practical significance.
Three. the utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide that a kind of simple in structure, grounding safety is reliable, long service life and non-maintaining high-tension cable long-life ground network.
The technical solution of the utility model is: a kind of high-tension cable long-life ground network, contain rack, described rack is provided with the conduction lead-out wire and the conductive earthing utmost point, described rack is formed by connecting by annular peripheral frame and latticed central frame, described annular peripheral frame by copper bar around being formed by connecting, its broken end place is plugged in the pipe joint and welding is fixed, described latticed central frame is formed by the copper bar interconnection, the broken end of copper bar infall is plugged in the pipe joint and welding is fixed, and described latticed central frame and described annular peripheral frame are pegged graft by pipe joint and welded fixing.
The cross sectional shape of described copper bar is circle or rectangle.Described pipe joint is two pass joints, or is three-way connection, or is geneva cross.
The beneficial effects of the utility model are:
1, the utility model adopts copper bar to make ground network, its long service life, the one, because copper is not the active metal, be difficult for being corroded, the 2nd, copper can produce the very strong oxide of a kind of adhesive force---verdigris, the formation that this oxide plays blocking-up and delays to corrode on the surface of copper in by the process of soil corrosion, can reach 30-60 its useful life, satisfy the requirement of substation operation time fully, guaranteed the safe and reliable operation of electrical network greatly, reach non-maintaining requirement simultaneously.
2, the utility model is made of annular peripheral frame and latticed central frame, and its broken end place adopts elbow, three-way connection or geneva cross to peg graft, and welding is fixing, is connected firmly, and ground connection is effective.
3, the utility model is chosen circle or rectangle copper bar making ground network according to the voltage height and the diameter of cable, and amount just is suitable for, and controls cost.
4, the utility model is simple in structure, grounding safety is reliable, long service life and non-maintaining, and it is applied widely, has good economic benefit after the popularization.
Four. description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is one of cross sectional shape of copper bar among Fig. 1;
Fig. 3 be copper bar among Fig. 1 cross sectional shape two.
Five. embodiment:
Embodiment: referring to Fig. 1-Fig. 3, among the figure, 1-copper bar, 2-pipe joint, the 3-conductive earthing utmost point, 4-conduct electricity lead-out wire.
High-tension cable long-life ground network contains rack, rack is provided with the conduction lead-out wire 4 and the conductive earthing utmost point 3, conduction lead-out wire 4 is connected with high-tension cable, the conductive earthing utmost point 3 contacts with the earth, rack is formed by connecting by annular peripheral frame and latticed central frame, annular peripheral frame by copper bar 1 around being formed by connecting, its broken end place is plugged in the pipe joint 2 and welding is fixed, latticed central frame is formed by copper bar 1 interconnection, the broken end of copper bar 1 infall is plugged in the pipe joint 2 and welding is fixed, and latticed central frame and annular peripheral frame are fixing by pipe joint 2 grafting and welding.
The cross sectional shape of copper bar 1 is circle or rectangle, determines as required.Pipe joint 2 is two pass joints, or is three-way connection, or is geneva cross, and it specifically is provided with referring to Fig. 1.
