Abstract
The utility model discloses a kind of wind-deviation insulator, comprise insulator, excellent core and T-shaped termination, described excellent core is inner at insulator, insulator and excellent core Joint, described excellent core one end of stretching out outside insulator is T-shaped termination, is stiff end, and the other end is terminals.T-shaped termination is connected by bolt with cross-arm, bolt is provided with nut, at described cross-arm and nut, directly disc spring is set, disc spring can absorb a part of deflecting force of wind, the radial stress that insulator post is born reduces, not fragile insulator, thus the useful life of wind-deviation insulator can be increased.Described insulator is the umbrella leaf of continuously spiral structure, and the umbrella leaf of continuously spiral structure is coiled in excellent core periphery, expands the bonded area of umbrella leaf and excellent core, thus obtain larger holding power, and it is high that helical structure has mechanical strength, the advantages such as self-cleaning ability is good, temperature rise balance.
Description
Technical field
The utility model relates to a kind of insulator, more specifically a kind of wind-deviation insulator.
Background technology
Along with developing rapidly of China's electric utility, in transmission line construction, transformation, except part transmission line changes into except cable laying, most transmission line still adopts built on stilts form.And frame is aerial in height, the power network line be exposed to the outside is very great by the impact of weather, is wherein one of principal mode of high ammonia syrings breaking by large wind-induced windage yaw discharge breaking phenomenon.General composite insulator is lightweight, self stable connection is not high, under large wind effect, wire is easily waved with the wind, tangent tower insulator string or strain tower jumper string easy angle of oscillation under wind effect is excessive, cause conduction to tower body electric discharge, line tripping, wire arc burn, the disconnected phenomenon such as stock, broken string occur.
Summary of the invention
The purpose of this utility model is to provide a kind of non-damageable, the wind-deviation insulator of the total quality had.
For achieving the above object, the utility model have employed following technical scheme: a kind of wind-deviation insulator, comprise insulator, excellent core and T-shaped termination, described excellent core is inner at insulator, insulator and excellent core Joint, described excellent core one end of stretching out outside insulator is T-shaped termination, is stiff end, and the other end is terminals; T-shaped termination is connected by bolt with cross-arm, and bolt is provided with nut, between described cross-arm and nut, arrange disc spring; Described insulator is the umbrella leaf of continuously spiral structure.
Improve as one, described disc spring is two, and lays respectively in two bolts on T-shaped termination, and between cross-arm and nut, described disc spring is circular cone disk like.Disc spring can absorb a part of deflecting force of wind, and the radial stress that insulator post is born reduces, not fragile insulator, thus can increase the useful life of wind-deviation insulator.
Improve as one, any two points on the umbrella edge line of the leaf one-tenth of umbrella of described continuously spiral structure is equal with the distance of described excellent core.It is peripheral that spiral helicine umbrella leaf is coiled in excellent core, expands the bonded area of umbrella leaf and excellent core, thus obtain larger holding power.
Improve as one, the umbrella leaf of described continuously spiral structure has the umbrella edge line of same diameter, revolving apart from equal from top to bottom.In use, pneumatic and rainwater blow brush under, there is particularly preferred self-cleaning dirt-removing power, overall temperature rise balance.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, a kind of wind-deviation insulator of the present embodiment, comprises insulator 1, excellent core 2 and T-shaped termination 3, described excellent core 2 is inner at insulator 1, insulator 1 and excellent core 2 Joint, and described excellent core 2 one end of stretching out outside insulator 1 is T-shaped termination 3, for stiff end, the other end is terminals; T-shaped termination 3 is connected by bolt 4 with cross-arm, and bolt 4 is provided with nut 5, arranges disc spring 6 between described cross-arm and nut 5; Described insulator 1 is the umbrella leaf of continuously spiral structure.
As a kind of embodiment of improvement, described disc spring 6 is two, and lays respectively in two bolts 4 on T-shaped termination 3, and between cross-arm and nut 5, described disc spring 6 is circular cone disk like.Disc spring 6 can absorb a part of deflecting force of wind, and the radial stress that insulator post is born reduces, not fragile insulator, thus can increase the useful life of wind-deviation insulator.
As a kind of embodiment of improvement, any two points on the umbrella edge line 7 of the leaf one-tenth of umbrella of described continuously spiral structure is equal with the distance of described excellent core 2.It is peripheral that spiral helicine umbrella leaf is coiled in excellent core 2, expands the bonded area of umbrella leaf and excellent core 2, thus obtain larger holding power.
As a kind of embodiment of improvement, the umbrella leaf of described continuously spiral structure has the umbrella edge line 7 of same diameter, revolving apart from equal from top to bottom.In use, pneumatic and rainwater blow brush under, there is particularly preferred self-cleaning dirt-removing power, overall temperature rise balance.
