Abstract

The utility model provides an energy -conserving connecting device of ground wire safety relates to the transmission facility field, including gripping fastener, insulator, the gold utensil cluster of ground wire, its characterized in that is still including installing in an insulator discharge gap on shaft tower top, through one fen streamline and ground wire electrical connection. Energy -conserving connecting device of ground wire safety had both guaranteed to reduce the thunderbolt by a wide margin and short -circuit current flows warp clamp gold utensil cluster, reduces fusing ground wire risk, can keep insulating to the shaft tower again when normal operating, realizes energy -conserving effect obvious on superhigh pressure, ultra -high voltage transmission line way, can also further realize exerting the heavy current ice -melt to the ground wire when the emergence freezes the calamity, reduces the broken string risk of freezing.

Description

A kind of ground wire energy-saving safe attachment means
Technical field
This utility model is related 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 setting up in the top of wire has one to two Ground wire, plays a part of to reduce thunder and lightning direct attack wire.In running, ground wire line-outage contingency often occurs.Due to ground wire In the top of wire, the wire below the easy touching of broken string further causes wire short circuit tripping operation, wire of burning, or even causes Conductor cord disconnection.The double loop transmission line of electricity that even multiloop sets up easily causes multi circuit transmission lines simultaneously once there is ground wire broken string Tripping operation, causes large area blackout.More serious situation be across railway, highway and oil and gas pipes 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 is pressed from both sides or strain clamp hardware fitting has that contact resistance is excessive with ground wire, the generation 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 playing reduces the risk of ground wire broken string.
Because supertension and UHV transmission line ground wire are very big by the electromagnetic induction of wire, the ground wire of shaft tower directly connects Ground, can cause a large amount of electric energy losses.Prior art is a piece of insulator of connecting in connection gold utensil string of the ground wire with shaft tower, and The insulator two 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 there is heavy-current discharge, causes mechanical performance to decline, cause broken string or the accident that goes offline.Prior art exists Safety conflicts with energy-conservation aspect presence.
In the multiple area of sleet, it is a kind of effective measure that ground wire connect high current to be carried 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.
Utility model content
This utility model purpose is to provide a kind of ground wire energy-saving safe attachment means, both guarantees to be greatly reduced and is struck by lightning and short Road electric current flows through wire clamp hardware string, reduces fusing ground wire risk, can keep insulating shaft tower in normal operation again, realizes super Obvious energy-saving effect on high pressure, UHV transmission line, can also further realize applying ground wire when there is freezing disaster High current ice-melt, reduces the broken string risk that freezes.
To achieve these goals, this utility model provides a kind of ground wire energy-saving safe attachment means, including grips ground The wire clamp of line, insulator, hardware string, it is characterised in that also including the insulator arc-over gap for being installed on shaft tower top, Jing mono- Shunt 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 within shaft tower top angle and fixedly mounts.
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 installed in straight line or strain rod tower top, horn mouth It is opening up.
A kind of ground wire energy-saving safe attachment means of the present utility model, it is possible to achieve following beneficial effect:1st, it is ground wire Good interface channel is provided between shaft tower, it is to avoid the accident of lightning current and earth short circuit current fusing ground wire occurs, economical Benefit is notable with social benefit.2nd, to keep all fronts or graded insulation between ground wire and shaft tower, during normal operation faradism is avoided Stream loss, saves a large amount of electric energy.3rd, avoid the faradic current on ground wire that gold utensil is flowed through when normally running, junction produces small putting Electricity, the risk of ablation of accumulating over a long period fracture gold utensil is examined such that it is able to unnecessary holding normalization to hardware string infrared measurement of temperature at this The problem with the presence or absence of electric discharge is surveyed, maintenance work amoun is mitigated on the premise of safety is guaranteed.
Description of the drawings
Fig. 1 is a kind of structural representation of ground wire energy-saving safe attachment means of the present utility model.
Specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments describing this utility model in detail.
As shown in figure 1, a kind of ground wire energy-saving safe attachment means of the present utility model, including grip ground wire 4 wire clamp 5, Insulator 7, hardware string 6, also including the insulator arc-over gap 1 for being installed on the top of shaft tower 8, the shunt lines 3 of Jing mono- are electric with ground wire 4 Gas connects.
Insulator arc-over gap 1 is that, in the end of insulator 2, the other end is bent to loudspeaker by two round steel one end bolt connections The discharging gap of mouth-shaped.Insulator arc-over gap 1 is to be enclosed within the top angle of shaft tower 8 fixed peace by two panels L-shaped steel plate fixture 9 Dress.Installed in straight line pole top, iiared port is upward.The insulator in insulator arc-over gap 1 is silicone rubber.
