The invention is further described with reference to the accompanying drawings and specific embodiments.
The embodiment is a bushing insulator, which is one of insulators and comprises a wall bushing for a power station, a transformer bushing for electrical equipment, an oil switch bushing and the like; the outdoor bushing insulator is used for connecting a current-carrying conductor of an indoor power distribution device with an outdoor current-carrying conductor and is greatly influenced by outdoor environment.
As shown in fig. 1, fig. 1 is a schematic structural diagram of a bushing insulator according to a preferred embodiment of the present invention.
The sleeve insulator includes sleeve pipe 1 a plurality of first full sheds 2 and the cover that the interval set up on the sleeve pipe 1 are located at least one second full shed 3 on the sleeve pipe 1, adjacent two are located to second full shed 3 between the first full shed 2, be equipped with ripple 31 on the second full shed 3, ripple 31 makes liquid on the second full shed 3 is the pearl and drips.
The application provides a bushing insulator is equipped with second full skirt 3, increase creepage distance improves bushing insulator's antifouling ability, and be equipped with on the second full skirt 3 ripple 31 utilizes ripple 31 makes liquid on the second full skirt 3 is the pearl drippage, even there is salt dirt on the second full skirt 31, and the salt solution that forms when raining also can not form the water film, is the pearl drippage and is difficult for constituting electrically conductive channel and cause creepage, reduces discharge even ground fault, avoids taking place the power failure accident, ensures the production steady operation.
The sleeve 1 is a main body of the sleeve insulator, is hollow inside and is used for placing a current-carrying conductor.
The first umbrella skirt 2 plays a certain degree of protection for the current-carrying conductor in the sleeve 1, avoids the influence of weather or electric corrosion, and provides a certain creepage distance.
Further, sleeve pipe 1 with first full skirt 2 is structure as an organic whole, guarantees the gas tightness, prevents that filth or steam from getting into.
Furthermore, the first umbrella skirt 2 is a porcelain umbrella skirt or a glass umbrella skirt, and has good insulation property.
The second umbrella skirt 3 further increases the creepage distance and improves the antifouling capacity of the bushing insulator. The number of the second sheds 3 is at least one, and of course, the number of the second sheds 3 may also be multiple, and is determined according to the voltage class of the bushing insulator.
Further, the second shed 3 comprises a proximal end 32 close to the sleeve 1 and a distal end 33 remote from the sleeve 1, and the corrugations 31 extend from the proximal end 32 in the direction of the distal end 33. Ripple 31 will the surface separation of second full skirt 3 is a plurality of regions, makes liquid on the second full skirt 3 is the pearl and drips, even there is salt dirt on the second full skirt 31, and the salt water that forms when raining also can not form the water film, is the pearl and drips and is difficult for constituting conducting channel and causes the creepage, reduces and discharges even ground fault.
Further, the corrugation 31 may be a straight line or a curved line; when the number of the corrugations 31 is large, the corrugations 31 may be all the same lines or may be different lines; or may be partially identical.
