Description

A kind of ground wire deicing insulation suspension string
Technical field
The utility model belongs to ground wire deicing technical field, and in particular to a kind of ground wire deicing insulation suspension string.
Background technology
Air is abnormal, and natural calamity takes place frequently, and lead wire and earth wire in transmission line icing is serious, causes down tower, line-outage contingency, gives power grid Bring very big destruction.To solve grounded-line icing disaster, need to carry out ice-melt to grounded-line.
Conducting wire ice-melt at present has had mature experience, solves the problems, such as wire icing.And ground wire due to the mode of connection with Conducting wire has essential distinction, and (i.e. conducting wire needs to convey electric current, is designed as insulation against ground;And ground wire is to protect conducting wire from being struck by lightning, one As be designed as ground connection or single-point grounding), ground wire will realize ice-melt, it is necessary to first by all fronts ground wire insulation get up, ground wire suspension string And strain insulator-string is intended to install insulator additional, forms ground wire insulator string.
Due to ground wire deicing generally use DC current ice-melt, ground wire string is subjected to ± 10kV~± 20kV ice-melt voltages, Meanwhile when ground wire is by being struck by lightning, need to make ground wire transient earthing, does not influence the lightning protection effect of ground wire, the insulation of conventional ground wire String is unsatisfactory for requiring.
The suspension string therefore it provides a kind of flexible ground wire deicing of connection insulate, can bear ice-melt voltage and influence ground Line lightning protection effect becomes those skilled in the art's urgent problem to be solved.
Utility model content
The utility model solve the technical issues of be:A kind of flexible ground wire deicing insulation suspension string of connection is provided, is solved existing The problem of ice-melt voltage can be born and influence ground wire lightning protection effect by having in technology ground wire insulation that cannot meet simultaneously.
The technical solution adopted in the utility model is as follows:
A kind of ground wire deicing insulation suspension string, including hardware, U-shaped link, duplex plate, connection gold utensil, ground wire deicing The upper end of composite insulator and ground wire suspension clamp, hardware is connect with engineering steel tower, the lower end centre position of hardware Duplex plate is connected by U-shaped link, it is compound absolutely that duplex plate lower part both ends are connected with a string of ground wire deicings by connection gold utensil respectively Edge, often go here and there ground wire deicing composite insulator bottom end connection there are one ground wire suspension clamp, connection gold utensil is hanging plate or link, Ground wire suspension clamp is connect with ground wire.
Further, connection gold utensil is PS hanging plates or U-shaped link (according to composite insulator hanging point moulder moisture).
Further, ground wire deicing composite insulator is the ground wire deicing composite insulator in tape insulation gap.
Further, two string ground wire deicing composite insulators are symmetrical.
Compared with prior art, the utility model has the advantages that:
The utility model is simple in structure, and design is scientific and reasonable, connected between each part of serial type it is reliable, flexibly, do not suppress and do not block, should String can bear ice-melt voltage, when ground wire is by being struck by lightning, and can make ground wire transient earthing, not influence the lightning protection effect of ground wire, And composite insulator will not block suppress it is disconnected.
The insulation suspension string of the utility model is single hanging point duplex string, connects steel tower and ground wire.The utility model duplex plate Connection gold utensil between ground wire deicing composite insulator is PS hanging plates or U-shaped link, to adapt to the ground wire of different hanging point patterns Ice-melt composite insulator, the connection gold utensil make duplex plate and ground wire deicing composite insulator energy flexible rotating, and connection is reliably, no It suppresses and does not block, ensure that hardware and ground wire deicing composite insulator fair line road, horizontal path direction can flexibly be swung.It solves When ground wire string both sides vertical loads is different or ice-shedding, ground wire deicing composite insulator and connection gold utensil relatively rotate When, ground wire deicing composite insulator leads to disconnected the problem of joining because card is suppressed.
Ground wire deicing composite insulator tape insulation gap in the utility model, in ground wire deicing, ground wire is advised by designing When fixed ground wire deicing electric current, insulator is not breakdown, ensures effective insulation of ground wire;When ground wire is by being struck by lightning, ground wire is exhausted The presence of intermarginal gap can make ground wire deicing composite insulator gap breakdown that suspension string be made to be grounded, between having ensured that lightning current passes through Gap smoothly flows into the earth, does not interfere with the lightning protection effect of ground wire.
