Abstract
The utility model provides a guard ring allowing live line connection and disconnection, belongs to the technical field of wire connection between a high-voltage line and a transformer, and mainly solves the problems that the prior guard ring needs to be lapped when the power is off, the electrical conductivity is worse, and the contact accidents between connecting wires of electrified wire clipsare caused easily. The guard ring allowing the live line connection and disconnection is mainly characterized in that the guard ring comprises a ring stand and wire clips arranged on the ring stand side by side; a hanging ring is arranged between the wire clips; the ring stand comprises a ring stand beam and a wire clip ring which is arranged on both sides of the ring stand beam; upper clips of the wire clips are fixedly connected with the ring stand beam; lower clips are connected with screws passing through the ring stand beam; and circular rings are arranged at the outer ends of the screws.The utility model is characterized by simple structure, original conception, good electric conduction effect, very convenient operation and live line connection and disconnection, and is mainly usedfor the guard rings that are connected with the high-voltage line and can allow the live line connection and disconnection.
Description
Technical field
The utility model belongs between high-tension bus-bar and the transformer and is connected the Power-line technology field, be specifically related to a kind of be used for being connected with high-tension bus-bar can chargedly take the guard ring of tearing open.
Background technology
At present; high-tension bus-bar comprises connecting line, hot line clamp and guard ring with the electric wire that is connected between the transformer, wherein, guard ring by broken skin circle line at two ends and the centre be wrapped in high-tension bus-bar (10KV) and go up and form two links; during use, hot line clamp is installed on one of them link.There is following weak point in existing guard ring: the one, and the overlap joint guard ring is the operation that must have a power failure, perhaps professional live line working construction, and can not adopt insulating rod to operate, very inconvenient, and professional live line working construction cost height, specialty needs more than 100 ten thousand with car, and influenced by geographical environment, and some local car advances not go; The 2nd, become by broken rubber-insulated wire circle, lack of standardization, conductivity is relatively poor; The 3rd, the guard ring broad has 30 centimeters intervals, like this, when certain hot line clamp damages, and when adorning hot line clamp once more on another link, easily causes this hot line clamp connecting line and other the touching accident of the connecting line of high-voltage line mutually; The 4th, guard ring is made with the ordinary steel core aluminum stranded wire, contact with hot line clamp bad, imprecision; The 5th, when handling, the guard ring insulating needs bigger cover, cost height; The 6th, be subjected to the influence of lead and guard ring spacing when hanging hot line clamp, inconvenience is hung.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure at above-mentioned weak point exactly, and novel, conductive effect is good, operation is very convenient, can chargedly take the guard ring of tearing open.
Technical solution of the present utility model is: a kind ofly can chargedly take the guard ring of tearing open, it is characterized in that: comprise ring stand and be arranged side by side wire clamp on this ring stand; Be provided with link between the wire clamp; Ring stand comprises the ring stand beam and is arranged on the wire clamp ring of ring stand beam both sides; The folder of going up of wire clamp is fixedlyed connected with the ring stand beam, and following folder is connected with the screw rod that passes the ring stand beam, and the outer end of screw rod is provided with annulus.
Be provided with the soft copper connecting line between the following folder of the wire clamp described in the utility model technical solution and the ring stand beam.
The screw rod that passes the ring stand beam described in the utility model technical solution is made of upper and lower two sections screw rods, and the epimere screw rod passes the ring stand beam and is connected with the following folder of wire clamp, and the hypomere screw rod is connected with the epimere screw flight.
The utility model is because employing can chargedly be taken the guard ring of tearing open by what ring stand and wire clamp constituted; ring stand is made of ring stand beam and the wire clamp ring that is arranged on ring stand beam both sides; the folder of going up of wire clamp is fixedlyed connected with the ring stand beam; following folder is connected with the screw rod that passes the ring stand beam; the outer end of screw rod is provided with annulus; be provided with link between the wire clamp; thereby when the operation of overlap joint guard ring; can be directly tangle link between the wire clamp with insulating rod; folder on the wire clamp of guard ring is hung on the high-tension bus-bar (10KV); and then the outer end annulus rotation of entangling screw rod with insulating rod; folder and last clamping are held together, high-tension bus-bar is hung jail and closely contact, with insulating rod hot line clamp is installed on the wire clamp ring more at last; promptly finish whole overlap joint guard ring operation, and need not to have a power failure.The utility model is owing to adopt cast aluminium to make, thereby tightr with being connected of high-voltage line and hot line clamp, more reliable.The utility model has the installation site of four hot line clamps owing to adopt two wire clamp rings, not only manys two installation sites than existing guard ring, and also avoids the touching accident between the hot line clamp connecting line when changing hot line clamp.The utility model need not bigger cover, thereby has reduced cost because compact conformation is shorter relatively.Compare traditional guard ring, the utlity model has simple in structurely, novel, conductive effect is good, operation is very convenient, can chargedly take the characteristics of tearing open.The utility model be mainly used in be connected with high-tension bus-bar can chargedly take the guard ring of tearing open.
