Description

A kind of ground wire energy-saving safe attachment means
Technical field
The present invention relates to field of transmission equipment, and in particular to a kind of ground wire energy-saving safe attachment means.
Background technology
Transmission line of electricity is responsible for long distance delivery electric power in power system.Generally being set up in the top of wire has one to two Ground wire, playing a part of, which reduces thunder and lightning, attacks wire directly.In the process of running, ground wire line-outage contingency often occurs.Due to ground wire In the top of wire, break the easily wire below touching, further causes wire short circuit tripping operation, wire of burning, or even cause Conductor cord disconnection.The double loop transmission line of electricity that even multiloop is set up easily triggers multi circuit transmission lines simultaneously once ground wire broken string occurs Tripping operation, causes large area blackout.More serious situation be across railway, highway and oil-gas pipeline wire, Line broken string causes secondary disaster, property very severe.
According to operating experience, the significant portion break point of ground wire is in the junction with shaft tower.Common broken string reason is outstanding Vertical line presss from both sides or strain clamp hardware fitting has that contact resistance is excessive with ground wire, is produced in excessive lightning current or short-circuit current rush High temperature, fused ground wire.The technology of application number 2016101455658 and 2016208439098 of the applicant realizes increase thunder Electric current and the second channel of short circuit current shunting, greatly reduce the electric current for flowing through suspension clamp or strain clamp hardware fitting, from And play the risk for reducing ground wire broken string.
Because super-pressure and UHV transmission line ground wire are very big by the electromagnetic induction of wire, the ground wire of shaft tower directly connects Ground, a large amount of electric energy losses can be caused.Prior art is a piece of insulator of being connected in connection gold utensil string of the ground wire with shaft tower, and The insulator both ends are installed by discharging gap.The ground wire connection scheme of prior art has both mechanical fasteners power and conductive channel simultaneously, Ground wire or gold utensil are burnt out when heavy-current discharge be present, causes mechanical performance to decline, triggers broken string or the accident that goes offline.Prior art exists Safety conflicts with existing in terms of energy-conservation.
In the multiple area of sleet, it is a kind of effective measure that high current is connected to ground wire and carries out ice-melt.This needs Ground wire keeps state of insulation with most of shaft tower in normal operation.Shunt line short circuit ground wire and shaft tower meeting using prior art Cause that great current deicing measure can not be used.
The content of the invention
Present invention aims at a kind of ground wire energy-saving safe attachment means are provided, both ensure thunderbolt and short circuit current stream is greatly reduced Through wire clamp hardware string, fusing ground wire risk is reduced, and can keeps insulating to shaft tower in normal operation, realized in super-pressure, spy Obvious energy-saving effect on ultra-high-tension power transmission line, it can also further be realized when freezing disaster occurs and high current is applied to ground wire Ice-melt, reduce the broken string risk that freezes.
To achieve these goals, the invention provides a kind of ground wire energy-saving safe attachment means, including ground wire is gripped Wire clamp, insulator, hardware string, it is characterised in that also include the insulator arc-over gap for being installed on shaft tower top, through a shunting Line is electrically connected with ground wire.
Above-mentioned ground wire energy-saving safe attachment means, it is characterised in that described insulator arc-over gap is by two round steel one Terminal bolt is connected to insulator end, and the other end is bent to the discharging gap of bell shape.
Above-mentioned ground wire energy-saving safe attachment means, it is characterised in that described insulator arc-over gap is cut by two band steels The discharging gap for bell shape is cut into, is clamped and connected in insulator end.
Above-mentioned ground wire energy-saving safe attachment means, it is characterised in that described insulator arc-over gap is by two panels L-shaped Steel plate fixture is enclosed on shaft tower top angle and is fixedly mounted.
Above-mentioned ground wire energy-saving safe attachment means, it is characterised in that the insulator in described insulator arc-over gap is silicon Rubber or ceramics or glass.
Above-mentioned ground wire energy-saving safe attachment means, it is characterised in that at the top of straight line or strain rod tower, horn mouth It is opening up.
A kind of ground wire energy-saving safe attachment means of the present invention, it is possible to achieve following beneficial effect:1st, it is ground wire and bar Good interface channel is provided between tower, avoids lightning current and the accident of earth short circuit current fusing ground wire from occurring, economic benefit It is notable with social benefit.2nd, keep completely or graded insulation, avoiding induced-current from damaging during normal operation between ground wire and shaft tower Consumption, saves a large amount of electric energy.3rd, avoiding flowing through gold utensil during the induced-current normal operation on ground wire, junction produces fine discharge, Ablation of accumulating over a long period is broken the risk of gold utensil, is to hardware string infrared measurement of temperature detection at this so as to unnecessary holding normalization It is no the problem of electric discharge to be present, mitigate maintenance work amoun on the premise of safety is ensured.
Brief description of the drawings
Fig. 1 is a kind of structural representation of ground wire energy-saving safe attachment means of the present invention.
Embodiment
Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in figure 1, a kind of ground wire energy-saving safe attachment means of the present invention, including grip the wire clamp 5 of ground wire 4, insulation Son 7, hardware string 6, in addition to an insulator arc-over gap 1 on the top of shaft tower 8 is installed on, electrically connect with ground wire 4 through a shunt line 3 Connect.
Insulator arc-over gap 1 is to be bent to loudspeaker in the end of insulator 2, the other end by two round steel one end bolt connections The discharging gap of mouth-shaped.Insulator arc-over gap 1 is to be enclosed on the top angle of shaft tower 8 fixed peace by two panels L-shaped steel plate fixture 9 Dress.At the top of straight line pole, iiared port is upward.The insulator in insulator arc-over gap 1 is silicon rubber.
