Abstract
A synthetic silastic insulator as a substitute for existing high-voltage ceramic insulator is composed of internal and external insulating bodies and connecting part. Said internal insulating body is a high-strength glass steel rod. Said connecting part is metallic rod ends sleeving around the both end of internal insulating rod and fixed by pins. Said external insulating body is a protecting silastic cover with more skirt edges, which is one-pass formed and fully wraps the internal insulating body and connecting parts. Its advantages are high mechanical strength and insulating performance, not breaking easily, hydrophobic surface and high insulating voltage.
Description
The present invention relates to electric product, particularly is the insulator in the power transmission and transforming equipment.
The insulator that uses in the existing power transmission and transforming equipment is ceramic basically, is commonly called as porcelain vase, has occurred going here and there the toughened glass goods of dress in recent years.Because insulation property, the mechanical performance of insulator are directly connected to the normal operation of power circuit and equipment, personal safety.Therefore, the development of novel insulator just seems very necessary.
Purpose of the present invention is exactly that a kind of insulation property, mechanical performance is good, pollution flashover voltage is high insulator will be provided.
Form by interior insulator, outer insulator and connector for reaching the insulator that goal of the invention designs, interior insulator is a fiberglass extruding rod, connector for dowel fixes, be sleeved on fiberglass and push excellent two ends, end face has the metal caput that connects screw, and outer insulator is one-shot forming, wraps up the silicone rubber jacket of fiberglass extruding rod and the band full skirt of metal caput fully.
As the disc insulator of one of embodiment, the full skirt on the silicone rubber jacket of the utility model insulator can multiplely be provided with, and size is alternate, and two ends are the major diameter full skirt.The full skirt end face is preferably sphere, and the inside is that plane, full skirt edge section are circle.
Silicon rubber synthetic insulators of the present invention is born mechanical load with fiberglass extruding rod and metal caput, and intensity is very high, easy fracture not, and insulation property are also good; Silicone rubber jacket and multiple full skirt can provide necessary electricity to leak distance as outer insulator.Because silicon rubber has excellent hydrophobicity, even the thicker pollution layer of insulator surface deposition, filthy surface also can present good hydrophobicity.Under the atmospheric environment of mist, dew and drizzle humidity, the composite insulation sub-surface can only condense into the trickle globule, can not form continuous moisture film, thereby reduces leakage current, improves pollution flashover voltage.Through down test of the same terms, the pollution flashover voltage of synthetic insulator is higher more than 50% than porcelain vase, and breakdown strength is better than 4 times of porcelain vases, have need not zero value detection etc. premium properties.And the shaped design of full skirt and big or small full skirt are placed creep distance and the self-cleaning performance that has more improved insulator at interval.
Below in conjunction with accompanying drawing the present invention is described.
Fig. 1 is an embodiment of the invention anti-fouling type disc insulator schematic diagram.
As shown in Figure 1, insulator is interior insulator by high strength glass fiber reinforced plastic extruding rod 10.Connector is fixing with pin 3, is sleeved on fiberglass and pushes excellent 10 two ends, and end face has the metal caput 2 that connects screw 1.Outer insulator is the silicone rubber jacket 9 with large and small full skirt 8 and 4 that wraps up fiberglass extruding rod 10 and metal caput 2 fully.Big full skirt 8 is alternate with umbellule skirt 4, multiple setting.Large and small full skirt 8 and 4 end face 7 are sphere, and the inside 5 is the plane, and full skirt edge 6 sections are circle.
Claims (3)
1, a kind of insulator, it is characterized in that said insulator is made up of interior insulator, outer insulator and connector, interior insulator is a fiberglass extruding rod, connector for dowel fixes, be sleeved on fiberglass and push excellent two ends, end face has the metal caput that connects screw, and outer insulator is one-shot forming, wraps up the silicone rubber jacket of fiberglass extruding rod and the band full skirt of metal caput fully.
2, insulator according to claim 1 is characterized in that the multiple setting of full skirt on the said silicone rubber jacket, and size is alternate, and two ends are the major diameter full skirt.
