Abstract

The invention belongs to the machinery technical field and relates to a temporary connection system of aerial cables. With the temporary connection system adopted, technical problems such as inconvenient temporary connection of existing aerial cables can be solved. The temporary connection system comprises a positive-pole cable and a negative-pole cable; the positive-pole cable includes a positive-pole conductor and two sections of positive-pole sheaths, wherein the positive-pole conductor is sleeved with a corrugated tube A and a corrugated tube B; the negative-pole cable includes a negative-pole conductor and two sections of negative-pole sheaths, wherein the negative-pole conductor is sleeved with a corrugated tube C and a corrugated tube D; the temporary connection system also comprises a connection bracket; the connection bracket is provided with a positive-pole contact and a negative-pole contact; one end of the positive-pole contact is in contact with the positive-pole conductor, and the other end of the positive-pole contact is connected with a positive-pole external connection wire; and one end of the negative-pole contact is in contact with the negative-pole conductor, and the other end of the negative-pole contact is connected with a negative-pole external connection wire. The temporary connection system of the invention has the advantages of convenient connection and the like.

Description

technical field

[0001] The invention belongs to the technical field of machinery and relates to a temporary connection system for overhead cables. Background technique

[0002] In the construction of the power system, overhead cables are used for long-distance transmission, medium-voltage power cables are used for transmission and distribution in the middle part, and low-voltage power cables are used for power transmission to households. Aerial cables have the characteristics of less investment and simple construction and laying. Among them, the single-core insulated overhead cable is composed of aluminum stranded wires, insulation wrapped around the aluminum stranded wires, and possibly a sheath wrapped outside the insulation. The multi-core stranded insulated overhead cable is made of multiple single-core insulated overhead cables and steel-cored aluminum stranded wires. These two cables are common overhead cables with good power transmission performance.
