Abstract
The utility model relates to a kind of overhead transmission line limit for height Sign Board, it is characterized in that: this limit for height Sign Board is provided with front insulator (1) and rear insulator (2), the outside surface of front insulator (1) and rear insulator (2) arranges reflectorized material marking plate (6) respectively; Front insulator (1) is relative with on rear insulator (2) is provided with cable duct (3), the corner of front insulator (1) and rear insulator (2) and reflectorized material marking plate (6) is respectively equipped with screw (4), by screw (4) utilize bolt (5) by front insulator (1) and rear insulator (2) structure in aggregates, described reflectorized material marking plate (6) is marked with caveat and limit for height number (7).The utility model is that a kind of 10kV or 0.4kV power overhead network limit for height indicates, and uses this nameplate to substantially increase the safe reliability of power circuit.
Description
Technical field
The utility model belongs to power circuit facility technology field, particularly relates to that a kind of crossing highway etc. is convenient to pedestrian on overhead power line, the limit for height of vehicle identification indicates.
Background technology
To places such as overhead line conductor crossing highway, passageways, for preventing vehicle, pedestrian touches wire, causes danger, and arranges overhead transmission line limit for height Sign Board through the obvious place that is everlasting.And be not easy to hang as a kind of line identification board, and bare conductor can make Sign Board charged.Therefore the Sign Board be directly suspended on overhead transmission line is seldom had.
Summary of the invention
The purpose of this utility model is the deficiency that cannot hang Sign Board for aerial condutor, provides a kind of 10kV or 0.4kV power overhead network limit for height nameplate.Realizing the technical scheme that the purpose of this utility model takes is: a kind of overhead transmission line limit for height Sign Board, it is characterized in that: this limit for height Sign Board is provided with front insulator and rear insulator, the outside surface of front insulator and rear insulator arranges reflectorized material marking plate respectively; Front insulator is relative with on rear insulator is provided with cable duct, the corner of front insulator and rear insulator and reflectorized material marking plate is respectively equipped with screw, by screw utilize bolt by front insulator and rear insulator structure in aggregates, described reflectorized material marking plate is marked with caveat and limit for height number.
The utility model is that a kind of 10kV or 0.4kV power overhead network limit for height indicates, and uses this nameplate to improve safe reliability greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of insulator in the utility model.
In figure, 1, front insulator, 2, rear insulator, 3, cable duct, 4, screw, 5, bolt, 6, reflectorized material marking plate, 7, caveat and limit for height number, 8, electric power overhead wire.
Embodiment
With reference to accompanying drawing, a kind of overhead transmission line limit for height Sign Board, is characterized in that: this limit for height Sign Board is provided with front insulator 1 and rear insulator 2, and the outside surface of front insulator 1 and rear insulator 2 arranges reflectorized material marking plate 6 respectively; Front insulator 1 is relative with on rear insulator 2 is provided with cable duct 3, the corner of front insulator 1 and rear insulator 2 and reflectorized material marking plate 6 is respectively equipped with screw 4, by screw 4 utilize bolt 5 by front insulator 1 and rear insulator 2 structure in aggregates, described reflectorized material marking plate 6 is marked with caveat and limit for height number 7.
During use, front insulator 1 and rear insulator 2 are separated, electric power overhead wire 7 is located in cable duct 3, utilizes bolt 5 to be fixed on electric power overhead wire 8 by screw 4.
