Description
Technical field
The present invention relates to transmission line of electricity O&M technical fields, more particularly to a kind of secondary guarantor of power line tension drainage string
Protection unit.
Background technique
Transmission line of electricity is chronically exposed to field, leads, the components such as ground wire, insulator, connection gold utensil are for a long time by the work of wind-force
With especially strain rod tower drains wire jumper insulator chain, since stress is different from strain insulator-string and straight line insulator string, in wind-force
Effect, be more easier dancing occur, wire jumper insulator at cross-arm be bolted, in the process of running, insulator by
Wind-force is flapped generated vibration, and connection bolt is passed to, and is caused shaft tower bolt nut to loosen, fall off, is eventually led to drainage
Wire jumper insulator falls off, and causes line fault.Preventing strain rod tower drainage wire jumper insulator chain from falling the main means of string at present is
Periodically step on bar inspection by personnel, fastening bolt is completed, and workload and security risk are increased.Invention power line tension draws
Stream string secondary protector can disposably solve drainage wire jumper insulator and fall off, fall the risk of string, it is reliable to improve line powering
Property.
Summary of the invention
In view of the above existing problems in the prior art, the present invention provides a kind of power line tensions to drain string second protection dress
Set, structure are as follows: cross-arm connector (1) is a U-board, is provided with screw hole on a face of U-board, inside there is fixing bolt A(8),
It is fixed on another face semicircle ring connector (2), is installed with intermediate connecting ring (3), intermediate connecting ring in semicircle ring connector (2)
(3) lower part is fixed with fixinig plate (4), and fixinig plate is provided with long hole A(5 on (4)), insulator clips (6) are symmetrical Ω shape,
The both ends of insulator clips (6) are provided with long hole B(7), two insulator clips (6) pass through long hole B by bolt B (10)
(7) and long hole A(5) connect with fixinig plate (4).The insulator clips (6) are porcelain insulator clips or compound inslation
Sub- clips, wherein porcelain insulator clips both ends are short conjunction plane, and composite insulator clips both ends are long conjunction plane.Institute
The cross section for stating insulator clips (6) is that lower end has a salient point (11).
Application method of the invention: power line tension drainage string secondary protector drains string cross-arm interconnecting piece by wire jumper
Point, the three parts composition such as the middle interconnecting piece of adjustable Zhang Changdu, width point and insulator clips, wherein insulator clips
For porcelain insulator clips or composite insulator clips.Two cross-arm coupling parts upper end is caught in wire jumper cross-arm when use
Tower material, tightens upper end bolt, and cross-arm coupling part lower end is fixed with semicircle ring connector, is installed with centre in semicircle ring connector and connects
Ring is connect, the lower part of intermediate connecting ring is fixed with fixinig plate, and long hole A is provided on fixinig plate, and insulator clips are symmetrical Ω shape,
The both ends of insulator clips are provided with long hole B, and two insulator clips pass through long hole B and long hole A and fixinig plate by bolt B
Connection.It is installed additional by livewire work, strain rod tower drainage jumper string can be effectively prevent to fall to go here and there the generation of accident.Middle interconnecting piece point
It is applicable in different length porcelain insulator, composite insulator, which has the long hole up and down for bolt, can root
It is adjusted according to cross-arm coupling part to length between the fixed device of insulator.Insulator clips are used to fix wire jumper insulator,
Middle circle diameter is less than steel insulator pin bowl diameter, tightens bolts at two ends, can play the fixed effect of insulator, and insulator is solid
Surely hoop cross section lower circumferential is to a salient point is equipped with, for more securely fixing insulator.
The beneficial effects of the present invention are: through the invention, the connection of insulator chain and steel tower is further enhanced, it can be with
It is installed additional under route not power-off condition, reduces line outage number；The apparatus structure is simple, light；The device is applicable in
In all kinds of 35-110kV route towers；The device length is short, does not influence line insulation, during transmission line of electricity O&M, repairing,
It effectively prevents power line tension drainage jumper string and falls the accidents such as string, fault trip.
