Description

Protective rings that can be disconnected while live

technical field

The utility model belongs to the technical field of electric wires connected between high-voltage electric wires and transformers, and in particular relates to a protective ring that can be connected with high-voltage electric wires and can be charged and disassembled.

Background technique

At present, the connecting wires between the high-voltage wires and the transformer include connecting wires, live wire clamps and protective rings, wherein the protective rings are wound on the high-voltage wires (10KV) at both ends and in the middle by broken wires and form two hanging rings , when in use, clip the live wire clip onto one of the hanging rings. The existing protective rings have the following disadvantages: First, the overlapping protective rings must be operated in a power failure, or professional live work construction, and insulation rods cannot be used for operation, which is very inconvenient, and the construction cost of professional live work is high, and professional vehicles are required. It needs more than 1 million yuan, and due to the influence of the geographical environment, cars cannot enter in some places; the second is made of broken wire turns, which are not standardized and have poor conductivity; the third is that the protective ring is wider, with 30 cm intervals. When a live wire clip is damaged and the live wire clip is installed again on another hanging ring, it is easy to cause a contact accident between the connecting wire of the live wire clip and the connecting wire of the other high-voltage wire; the fourth is that the protective ring is made of ordinary steel-cored aluminum It is made of twisted wires, and the contact with the live wire clamp is not good and not tight; fifth, the protective ring needs a large cover during insulation treatment, which is costly; sixth, when the live wire clamp is suspended, it is affected by the distance between the wire and the protective ring, which is inconvenient suspension.

Contents of the invention

The purpose of this utility model is to provide a protection ring with simple structure, novel concept, good conduction effect, very convenient operation, and detachable when live.

The technical solution of the utility model is: a protective ring that can be built and disassembled with electricity, which is characterized in that: it includes a ring frame and wire clips arranged side by side on the ring frame; The ring frame beam and the wire clamp rings arranged on both sides of the ring frame beam; the upper clamp of the wire clamp is fixedly connected with the ring frame beam, and the lower clamp is connected with the screw passing through the ring frame beam, and the outer end of the screw rod is provided with a ring.

Soft copper connecting wires are provided between the lower clamp of the wire clamp described in the technical solution of the utility model and the ring frame beam.

The screw rod passing through the ring frame beam described in the technical solution of the utility model is composed of upper and lower two sections of screw rods, the upper section screw rod passes through the ring frame beam and is connected with the lower clip of the clamp, and the lower section screw rod is threadedly connected with the upper section screw rod.

Because the utility model adopts a protective ring that can be taken and disassembled when charged, the ring frame is composed of a ring frame beam and a wire clip ring arranged on both sides of the ring frame beam. Fixed connection, the lower clamp is connected with the screw rod passing through the ring frame beam, the outer end of the screw rod is provided with a ring, and a hanging ring is provided between the clamps, so when the lap protection ring is operated, the wire can be directly hung with an insulating rod The hanging ring between the clamps, hang the upper clamp of the protective ring on the high-voltage wire (10KV), and then use the insulating rod to cover the outer end of the screw and rotate the ring, so that the lower clamp and the upper clamp are closed, and the high-voltage wire Hang it firmly and make close contact, and finally use the insulating rod to clamp the live wire clamp to the wire clamp ring, that is, complete the operation of the entire overlapping protection ring without power failure. Because the utility model is made of cast aluminum, the connection with the high-voltage wire and the live wire clamp is tighter and more reliable. Because the utility model adopts two wire clip rings, it has four installation positions of live wire clips, which not only has two more installation positions than the existing protective ring, but also avoids the gap between the live wire clip connecting wires when replacing the live wire clips. touch accidents. Because the utility model has a compact structure and is relatively short, a large cover is not needed, thereby reducing the cost. Compared with the traditional protective ring, the utility model has the characteristics of simple structure, novel concept, good electric conduction effect, very convenient operation, and can be assembled and disassembled under electrification. The utility model is mainly used for a protective ring that can be built and disassembled when connected with high-voltage electric wires.
