Fig. 2 is becket schematic diagram；
Fig. 3 is scheme of installation；
Fig. 4 is insulator surface Potential distribution.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples.Following examples are only used for clearer
Ground illustrates the technical solution of the utility model, and can not limit the scope of protection of the utility model with this.
As shown in figure 1, a kind of antifouling creeping-increasing skirt of insulator, includes silicon rubber umbrella skirt 1 and becket 2；The silicon rubber
Full skirt 1 and becket 2 are bonded together by high temperature resistant moment glue；
As shown in figure 1, silicon rubber umbrella skirt 1 has bonding place 101, for installing fixed creeping-increasing skirt.The center of silicon rubber umbrella skirt 1 has
Centre bore 102, can be cut out according to insulator model makes creeping-increasing skirt be applied to different types of insulator.Becket 2 is bonded in silicon
The surface of rubber full skirt 1, there is an opening at bonding place 101.
As shown in Fig. 2 becket 2 has opening, connector 201 is installed thereon.Bolt hole 202 is provided with connector 201,
For fixing becket 2.Because becket 2 is connected with silicon rubber umbrella skirt 1, therefore becket 2 removes the function of playing grading ring, also may be used
To increase the mechanical strength of whole creeping-increasing skirt, make bonding place 101 difficult for drop-off.
Silicon rubber umbrella skirt 1 by increasing insulator creep distance to improve the pollution flashover voltage of insulator, and becket 2 play it is similar
In the effect of insulator equalizing ring.
It can improve insulator electric field distribution for checking this product, be climbed using finite element emulation software ANSYS to installing increasing additional
The porcelain long rod insulator of skirt carries out electromagnetic-field simulation, and research installs the utility model additional to porcelain long rod insulator current potential electric field point
The influence of cloth.During calculating, it is contemplated that insulator dielectric, arcing horn, grading ring, wire and steel tower are to voltage distribution of insulator
Influence, and assume that the electric charge on insulator metal cap keeps constant.It is more original-pack than less filling grading ring, installation during simulation calculation
Pressure ring, when head and end installs two panels this creeping-increasing skirt additional, installs three this creeping-increasing skirts additional insulator surface Potential distribution situation, with
Verify the equal pressure energy power of this creeping-increasing skirt, the installation site of creeping-increasing skirt is as shown in Figure 3.The installation site of creeping-increasing skirt is typically in insulator
The position such as head and the tail, with grading ring residing for locus it is more similar.
