Abstract
The utility model discloses an overhead line wire fixed structure, including a tower and an insulator strings, the insulator strings can fix the wire to a supporting frame of the tower top which can is detachably provides with two insulated boards, and two insulated boards after fixing the wire is arranged on both sides of the B-term wire. According to the utility model can effectively prevent bird damage caused by a power outage of in-phase short circuit, thereby avoiding the electric power accident.
Description
Technical field
The utility model relates to a kind of power equipment, particularly relates to a kind of overhead transmission line wire fixing structure.
Background technology
Overhead transmission line, English name is overhead line, refers to the transmission line with insulator, transmission pressure being fixed on the shaft tower that stands on ground with electric energy transmitting.It is comprised of wire, overhead ground wire, insulator string, shaft tower, earthing device etc. conventionally.Wire is made by conducting electricity good metal, has enough thick cross section (to keep suitable current density) and compared with larger radius of curvature (to reduce corona discharge).EHV transmission is the bundle conductors that adopt more.Overhead ground wire (claiming again lightning conducter) is arranged at the top of transmission pressure, for the protection of circuit, exempts from thunderbolt.Important transmission line is conventionally with two overhead ground wires.Insulator string is formed by single suspension type (or bar type) insulator serial connection, need meet the requirement of dielectric strength and mechanical strength.
Every insulator string number is determined by transmission voltage grade.Shaft tower is many to be made by steel or armored concrete, is the main support structure of overhead transmission line.The impact of the various natural conditions such as overhead transmission line will be considered in when design temperature Change, strong storm invasion and attack, lightning that it is subject to, drenches with rain, freezes, flood, wet fog, also will consider electromagnetic environment interference problem.Overhead transmission line through path, also to have enough ground width and a headroom corridor.
Overhead transmission line often has the phenomenon of birds nest to occur, and causes power distribution circuit to have a power failure, and causes the destruction of power equipment, serious may initiation fire, cause very large loss.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of overhead transmission line wire fixing structure.
The overhead transmission line wire fixing structure that the utility model provides, comprise shaft tower and insulator string, described insulator string can be fixed on electric wire on the bracing frame on described shaft tower top, on the bracing frame on described shaft tower top, removably be provided with two insulation boards, the fixing rear two described insulation boards of electric wire are arranged at the both sides of B item electric wire.
According to the utility model, can effectively prevent that the phase fault causing because of bird pest from having a power failure, and avoided the electric power accident bringing thus.
