Abstract
The invention discloses a tightening insulator, which comprises a first lantern ring, a second lantern ring and an insulator, the two lantern rings are sleeved with each other, and the insulator is wrapped outside the lantern rings. The tensile strength of the tightening insulator is enhanced by being connected with a butterfly part through a ring rod, and the prepared tightening insulator can withstand voltage of 42kV and allow tension of 90kN.
Description
Technical field
The present invention relates to a kind of insulated connecting piece, relate in particular to a kind of strain insulator.
Background technology
When the backguy of securing electric lines bar is passed through alive circuit or is closed on alive circuit, guy insulator must be set, can prevent the generation of the unexpected charged phenomenon of hurting sb.'s feelings of pull-down line like this.In addition, when insulating capacity is provided, also to guarantee enough tension mechanical strengths.Phenomenon of rupture often takes place in the guy insulator that uses at present, this is because steel strand wire can not fit like a glove with the installation circular arc of existing guy insulator at the circular arc that installation insulator place bends, so backguy is in a single day stressed, will produce stress concentration point at the two ends of circular arc, with great pulling force and minimum stress surface effect, and make the insulator fracture.
Summary of the invention
The object of the present invention is to provide a kind of strain insulator, improve the withstand voltage and tensile strength of strain insulator.
A kind of strain insulator comprises first collar, second collar and insulator.
First collar comprises first handle, the first ring bar and the first butterfly part, and the first butterfly part is provided with two through holes, and the first ring bar is arranged in two through holes and fixedlys connected with the first butterfly part.
Second collar comprises second handle, the second ring bar and the second butterfly part, and the second butterfly part is provided with two through holes, and the second ring bar is arranged in two through holes and fixedlys connected with the second butterfly part.
First collar and second collar are sheathed mutually, and insulator is wrapped in outside the first ring bar, the first butterfly part, the second ring bar and the second butterfly part.
Preferably, first collar and second thimble structure are identical.
Preferably, first handle and the second handle inboard are provided with groove.
Preferably, the first cover plane of a loop is vertical with the second cover plane of a loop.
Preferably, antifouling shirt rim on the insulator.
The beneficial effect that technical solution of the present invention realizes:
A kind of strain insulator disclosed by the invention, sheathed mutually by two collars, and at collar outer wrapping insulator.The present invention is connected the tensile strength that has strengthened strain insulator by the ring bar with the butterfly part, and the withstand voltage 42kV of strain insulator energy that makes allows pulling force 90kN.
Description of drawings
Fig. 1 is the structural representation of strain insulator;
Fig. 2 is the structural representation of the collar;
Fig. 3 is the structural representation of butterfly part.
Embodiment
Describe technical scheme of the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1, strain insulator of the present invention comprises first collar 1, second collar 2 and insulator 3.
First collar 1 comprises first handle 11, the first ring bar 12 and the first butterfly part 13.Second collar 2 comprises second handle 21, the second ring bar 22 and the second butterfly part 23.In the present embodiment, first collar 1 and second collar, 2 each modular constructions are identical.
First collar 1 and second collar 2 are sheathed mutually, and insulator 3 is wrapped in outside the first ring bar 12, the first butterfly part 13, the second ring bar 21 and the second butterfly part 22.First collar, 1 plane is vertical with second collar, 2 planes.Insulator 3 is provided with antifouling shirt rim 31.
The present invention's first collar 1 is referring to Fig. 2 and shown in Figure 3, and it comprises first handle 11, the first ring bar 12 and the first butterfly part 13.The first butterfly part 13 is provided with through hole 131,132.The first ring bar 1 is arranged in two through holes 131,132 and fixedlys connected with the first butterfly part 13.
The ring bar is connected the tensile strength that has strengthened strain insulator with the butterfly part, and the withstand voltage 42kV of strain insulator energy that makes allows pulling force 90kN.
