Abstract
The utility model discloses an aerodynamic disk hanging insulator, which comprises an iron cap, a steel foot and an umbrella disk, and is characterized in that one or a plurality of ridges are arranged below the umbrella disk, and the diameter of the umbrella disk is larger or equal to 330mm. The insulating part is made of glass, ceramics or other insulating materials. Even though the aerodynamic disk hanging insulator provided by the utility model can weaken the aerodynamics characteristics, the operating characteristic is easier to be matched with other types of insulators, and the creeping distance can be easily increased or reduced according to the insulation design requirements so as to enhance the operating electrical characteristic of insulator string.
Description
Technical field
The utility model relates to a kind of cap and pin insulator, especially relates to a kind of aerodynamic type cap and pin insulator, belongs to technical field of electricity.
Background technology
The aerodynamic type cap and pin insulator claims the straw hat type insulator again.Fig. 1 is existing aerodynamic type cap and pin insulator structural representation, and its design feature is that disk track is big, and lower surface is aerodynamic structures, because the said structure characteristics are difficult for forming eddy current, reduce contamination, but creepage distance is less.
The appearance of this product is placed hope on the circuit bunchiness and is used, and reduces contamination, improves operational reliability.But because disk track is big, creepage distance is little, does not reach the market prospective purpose.Yet at many birds area circuit, the normal topmost employing one of insulator string is product thus much, to block birds droppings, avoids the filthy whole insulator string of birds droppings surface.In the recent period, seriously regional at ice damage, begin to attempt in string, to use this product at interval, with the blocking-up icing, increase and protect creep distance.
Traditional structure aerodynamic type cap and pin insulator is connected with other structure insulator when using, and is less because of its creep distance, makes the voltage of insulator string distribute more inhomogeneous.When greasy weather or drizzle, its smooth upper and lower surface can be moistening fast, and voltage distributes and can concentrate to the insulator of other pattern, reduces the operation electric property of insulator string.
The utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes existing aerodynamic type cap and pin insulator, and a kind of aerodynamic type cap and pin insulator of operation electric property of reinforced insulation substring is provided.
For solving the problems of the technologies described above, the utility model provides a kind of aerodynamic type cap and pin insulator, comprises chapeau de fer, steel pin and insulating part, and described insulating part comprises umbrella disk, it is characterized in that: have one or more umbrella ribs at described umbrella disk, described umbrella disk diameter is more than or equal to 330mm.
Aforesaid aerodynamic type cap and pin insulator is characterized in that: its insulating part material is glass, pottery or other insulating material.
What the utility model reached produces effect:
Though aerodynamic type cap and pin insulator of the present utility model can weaken air dynamic behaviour, but its operation characteristic is easier to mate the insulator of other pattern, and can easily increase or reduce creep distance, the operation electrical characteristic of reinforced insulation substring by the insulating Design requirement.
Description of drawings
Fig. 1 is existing aerodynamic type cap and pin insulator structural representation;
Fig. 2 is an aerodynamic type cap and pin insulator structural representation of the present utility model.
Embodiment
Fig. 2 is an aerodynamic type cap and pin insulator structural representation of the present utility model.Can be with one or more umbrella ribs under its umbrella disk, the umbrella disk diameter is more than or equal to 330mm, and its insulating part material comprises glass, porcelain or other insulating material.Though can weaken air dynamic behaviour, its operation characteristic is easier to mate the insulator of other pattern, and can easily increase or reduce creep distance, the operation electrical characteristic of reinforced insulation substring by the insulating Design requirement.
Below disclose the utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within the protection range of the present utility model.
Claims (2)
1. an aerodynamic type cap and pin insulator comprises chapeau de fer, steel pin and insulating part, and described insulating part comprises umbrella disk, it is characterized in that: have one or more umbrella ribs at described umbrella disk, described umbrella disk diameter is more than or equal to 330mm.
2. aerodynamic type cap and pin insulator according to claim 1 is characterized in that: its insulating part material is glass, pottery.
