Abstract
The utility model discloses a pillar insulator of a composite core rod, which is provided with a flange (1), an epoxy glass fiber resin rod (2) and a composite silicon rubber umbrella skirt (3) at the outer layer. The pillar insulator is characterized in that a steel core rod (4) which is solidified with the epoxy glass fiber resin rod (2) into a whole is arranged at the inner part of the epoxy glass fiber resin rod (2). The advantages of the pillar insulator are as follows: the steel core rod is adopted as an inner core material of the pillar insulator; when in use, the bending resisting intensity and rigidity of the pillar insulator can be greatly improved, so as to solve the problem that the epoxy glass fiber resin rod can be easily deformed in the using process due to low bending resisting intensity and rigidity.
Description
Technical field
The utility model belongs to the insulator in the electric power power transmission and transforming equipment, and definite saying is a kind of composite core rod post insulator.
Background technology
For the post insulator that uses in the present power transmission and transformation line, except traditional ceramic leg insulator, relatively more novel is the silicon rubber composite post insulator.And the silicon rubber composite post insulator is because its inner core is an epoxy resin glass rod, has good electric property and tensile strength, but, when being applied to use as the switch post insulator, because the relatively poor easy diastrophic problem of himself rigidity, in the process of switch combination and disengagement, there is very big operate miss, causes operating barrier even operation failure.Designer of the present utility model has done research in earnest, has proposed goal of the invention of the present utility model.
Summary of the invention
Easy diastrophic defective of poor rigidity and not enough putting forward that goal of the invention of the present utility model exists in order to overcome present switch post insulator.A kind of composite core rod post insulator promptly is provided.
Technical solution of the present utility model is to realize like this, this kind composite core rod post insulator, has flange, epoxy glass fiber resin rodlet and outer field composite silicone rubber full skirt is characterized in that having the steel core bar that is cured as one with this epoxy glass fiber resin rodlet in the inside of epoxy glass fiber resin rodlet.Steel core bar can be with hollow steel pipe as plug.
Beneficial technical effects of the present utility model is: the steel plug is as the heart material of post insulator, in use, can greatly improve the flexural strength and the rigidity of post insulator, the flexural strength and the rigidity that have solved the existence of epoxy resin fiberglass rod are less, the problem that in use deforms.Can make post insulator, rod insulator.
Description of drawings
Accompanying drawing 1 is the structural profile schematic views of an embodiment of the utility model, and accompanying drawing 2 is structural profile schematic views of another embodiment.Sequence number in the accompanying drawings is described as 1, flange, and 2, the epoxy glass fiber resin rodlet, 3, the compound full skirt of silicon rubber, 4, steel core bar.
Embodiment
Below in conjunction with the embodiment that provides in the accompanying drawing, structure of the present utility model and use are elaborated.
Embodiment 1, with reference to accompanying drawing 1, this composite core rod post insulator has flange 1, epoxy glass fiber resin rodlet 2 and outer field composite silicone rubber full skirt 3 have the steel core bar 4 that is cured as one with this epoxy glass fiber resin rodlet 2 in the inside of epoxy glass fiber resin rodlet.This steel core bar also can adopt the structure of truncated cone section.
Claims (2)
