Abstract
The invention discloses a deicing ground wire with high-voltage heavy current. The deicing ground wire is manufactured by mixing at least two strands of steel strands (1) and two strands of insulated copper wires into a rope. The steel strands (1) uniformly distributed radially on the section of the ground wire form a Theta-shaped bead ring; and the insulated copper wires (2) are uniformly distributed on two sides of the steel strands (1) distributed on the radial line of the bead ring. The wire coated with ice can also be supplied with heavy-current for temperature rise and deicing by utilizing the characteristic of cold resistance of the insulated copper wires (2). The gravity of the overhead ground wire is supported by the steel strands (1) with tougher bearing capacity, and the normal operation of the transmission line is guaranteed. The deicing ground wire has the advantages that: 1) the ground wire maintains the normal functions of common ground wires and does not influence the work on the ground wire; 2) the ground wire is high voltage resistant and can be supplied with heavy current; 3) the ground wire is high temperature resistant and insulating layers are not damaged; and 4) the ground wire can be used for heavy-current deicing and greatly reduces the labor intensity of deicing.
Description
Technical field
The invention belongs to the electrical engineering equipment technical field, relate in particular to a kind of ice-melt ground wire by high-voltage great-current.
Background technology
In recent years, because of being subjected to the influence of freezing disaster, overhead ground wire broken string and remaining ground wire take place and drop and cause the lead short circuit to cause accidents such as line tripping on lead in transmission line repeatedly.After accident takes place, often need that overhead ground wire is carried out deicing and handle, and the ice-melting mode of being taked for a long time all is to carry out ice-melt by the big electric current that applies interchange or direct current to handle.But because overhead ground wire is formed uniqueness, mounting means is special, its insulation against ground insufficient strength, thereby it is limited to apply voltage, it is very big to add its resistance, so ice melting current is difficult to reach requirement, cause the overhead ground wire temperature to be difficult to raise, can't realize effective ice-melt all the time.
Summary of the invention
The technical problem to be solved in the present invention is at the backward situation of prior art facility, to provide a kind of ice-melt ground wire by high-voltage great-current, to satisfy the ice-melt demand at ice damage scene.
Technical solution of the present invention is, described a kind of ice-melt ground wire by high-voltage great-current, referring to Fig. 1, being rope form wire rod strand system by multiply steel strand wire 1 more than at least two strands and 2 mixing of the multiply insulated copper wire more than at least two strands forms, the cross section of this ground wire is " day " font pearl ring that equally distributed radially steel strand wire 1 are formed, and above-mentioned insulated copper wire 2 promptly is uniformly distributed in the radially both sides of the steel strand wire 1 that distribute on this pearl ring radial line.
Operation principle of the present invention is: utilize that insulated copper wire 2 is cold-resistant defies freezing characteristic, be used in after transmission line can guarantee the circuit icing as the part of ground wire, still can feed high-voltage great-current, heat up by integral body and realize ice-melt.And support the gravity of overhead ground wire with steel strand wire 1 more tough and tensile load function, guarantee the normal operation of transmission line conscientiously.
The invention has the beneficial effects as follows:
1), keep the normal function of common ground wire, do not influence the operation on the ground wire;
2), can be high pressure resistant by big electric current;
3), can be high temperature resistant and do not damage insulating barrier;
4), can be used to implement great current deicing, reduce the labour intensity of de-icing work greatly.
Description of drawings
Fig. 1 is the cross section structure schematic diagram of a specific embodiment of the present invention, is denoted as among the figure:
The 1-steel strand wire,
The 2-insulated copper wire.
Embodiment
A kind of like this ice-melt ground wire of this embodiment of the invention by high-voltage great-current, referring to Fig. 1, the GJ-70 type galvanized strand wires that its steel strand wire 1 adopt the BeiJing, China extra large electric power equipment of gold Co., Ltd to produce, area of section 70mm
2, diameter ￠ 11.0mm; Insulated copper wire 2 adopts the Chinese Shanghai friend to open up the QZY type plural layers high strength insulative cylinders shape copper cash that electromagnetism Co., Ltd produces.These two kinds of power transmission lines are by above-mentioned technical solution and with reference to shown in the accompanying drawing, get 15 strands with steel strand wire 1 and mix with 4 strand insulation copper cash 2 and to be the rope form wire rod and to twist to make and form.The cross section that makes this ground wire is " day " font pearl ring that equally distributed radially steel strand wire 1 are formed, and steel strand wire 1 are 12 strands on the ring, and steel strand wire 1 are 3 strands on the footpath.4 strand insulation copper cash 2 are uniformly distributed in the radially both sides of 3 strands of steel strand wire 1 on this radial line, and promptly radial line radially respectively distributes 2 strands in both sides.
How of the present invention a kind of ice-melt ground wire by high-voltage great-current of said structure through trial-production and repeatedly on probation through, all is proved to be respond well, and not only withstand voltage not only high temperature resistant but also safety reaches designing requirement fully.
