Abstract

The utility model relates to a kind of polyethylene umbrella-type insulator.Mainly solve that existing insulator dielectric effect is bad, mechanical strength is poor, the yielding problem of insulator umbrella.It is characterized in that: described main body (1) comprises inner core (4) and outer layer sleeve (5), described outer layer sleeve (5) is placed in the outside in inner core (4) stage casing, and described outer layer sleeve (5) external stability has 2 umbrella leaves (3); The right-hand member of described inner core (4) is internally connected with screw rod (2), the end face of left end has metallic channel (7), and the end face of metallic channel (7) both sides has screwed hole (6).This polyethylene umbrella-type insulator has that insulation effect is good, mechanical strength is good, the on-deformable feature of insulator umbrella.

Description

Polyethylene umbrella-type insulator
Technical field
The utility model relates to electricity field, specifically a kind of polyethylene umbrella-type insulator.
Background technology
Insulator is commonly called as porcelain vase, is used to the insulator of support wire.Insulator can ensure that wire and cross-arm, shaft tower have enough insulation.It is in operation and should be able to bears the loading of wire vertical direction and the pulling force of horizontal direction.It also undergos Exposure to Sunlight, drench with rain, the corrosion of climate change and chemical substance, and the safe operation of quality to circuit of insulator is very important.Therefore, insulator should have good electric property, has enough mechanical strengths again.At present, the medium voltage distribution network of China is substantially based on 10kV, but along with rapid economic development, existing 10kV distribution system capacity is little, the problem days such as loss is large are aobvious outstanding, and 20kV distribution line by comparison power supply capacity is large, and electric energy loss can reduce by 75%, meet national low charcoal energy-saving square umbrella, 20kV electrical network is imperative.Insulator is the main element of distribution line, and existing insulator, generally based on silica gel composite insulator, exists the problems such as insulation effect is not good, mechanical strength is poor, insulator umbrella is yielding, improper for 20kV electrical network.
Summary of the invention
In order to overcome, existing insulator dielectric effect is bad, mechanical strength is poor, the yielding deficiency of insulator umbrella, the utility model provides a kind of polyethylene umbrella-type insulator, and this polyethylene umbrella-type insulator has that insulation effect is good, mechanical strength is good, the on-deformable feature of insulator umbrella.
The technical solution of the utility model is: a kind of polyethylene umbrella-type insulator, and comprise main body, described main body comprises inner core and outer layer sleeve, and described outer layer sleeve is placed in the outside in inner core stage casing, and described outer layer sleeve external stability has 2 umbrella leaves; The right-hand member of described inner core is internally connected with screw rod, and the end face of left end has metallic channel, and the end face of metallic channel both sides has screwed hole.
The utility model has following beneficial effect: owing to taking such scheme, and main body is made up of inner core and outer layer sleeve, and inner core adopts high-intensity resin to make, and enhances the ability that this insulator bears voltage and mechanical load; Outer layer sleeve adopts polyethylene injection molded, and meanwhile, outer layer sleeve external stability has 2 umbrella leaves, adds creepage distance.This insulator has the advantages such as good insulating effect, mechanical strength is good, insulator umbrella is indeformable, goes for 20kv distribution line, and this insulator is easy to processing, and production cost is also lower.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-main body in figure, 2-screw rod, 3-umbrella leaf, 4-inner core, 5-outer layer sleeve, 6-screwed hole, 7-metallic channel.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of polyethylene umbrella-type insulator, comprises main body 1, and described main body 1 comprises inner core 4 and outer layer sleeve 5, and described outer layer sleeve 5 is placed in the outside in inner core 4 stage casing, and adapter sleeve is contained on inner core 4, and the two ends of inner core 4 are all exposed on the external.Inner core 4 adopts high-intensity resin to make, and enhances the ability that this insulator bears voltage and mechanical load; Outer layer sleeve adopts polyethylene injection molded, and described outer layer sleeve 5 external stability has 2 umbrella leaves 3, and 2 umbrella leaves are separately positioned on left end and the middle part of outer layer sleeve 5, and umbrella leaf 3 adopts polyethylene injection moulding equally, adds creepage distance.Wherein umbrella leaf 3 and outer layer sleeve 5 can make one, are convenient to processing and assembling like this.The right-hand member of described inner core 4 is internally connected with screw rod 2, the end face of left end has metallic channel 7, and the end face of metallic channel 7 both sides has screwed hole 6, and screwed hole 6 can be connected by screw gland, is compressed by the wire in metallic channel 7 by gland.
Described on end, this insulator has the advantages such as good insulating effect, mechanical strength is good, insulator umbrella is indeformable, goes for 20kv distribution line, and this insulator is easy to processing, and production cost is also lower.
Embodiment one: the entire length of this insulator is 282mm, the diameter of two panels umbrella leaf 3 is 190mm, and the distance between two umbrella leaves 3 is 80mm.
