Abstract
The utility model discloses a stain-resistant disk-shaped suspension insulator for a high-tension line, and relates to a suspension insulator. The stain-resistant disk-shaped suspension insulator comprises an iron cap (1), an insulation ceramic piece (3), a steel foot (5), a metal ring (6) and a stain-resistant coating (7); the iron cap (1) is adhered with the head of the insulation ceramic piece (3) through cement gel; the inner diameter of the insulation ceramic piece (3) is adhered with the steel foot (5) through the cement gel; the inner diameter of the metal ring (6) is matched with the outer diameter of the bottom of the iron cap (1); and the outer surface of an upper umbrella skirt (2) of the insulation ceramic piece (3) is coated with the stain-resistant coating (7). The stain-resistant disk-shaped suspension insulator can increase the creepage distance, improve flashover voltage, and guarantee that the high-tension line runs normally.
Description
Technical field
The utility model relates to a kind of suspension insulator, is specifically related to a kind of high-tension line resistant cap and pin insulator.
Background technology
Insulator is widely used in power distribution equipment, transformer and the device for switching of power plant and transformer station and on the transmission line; Be used for supporting and fixing naked current; And make naked current and ground insulation, or make mutual insulating between the current that is in different potentials in the device.Mainly be divided three classes: station insulator, apparatus insulator and line insulator, wherein line insulator is used for supporting, hanging or the fixedly lead of overhead transmission line and the soft bus of switchyard, and makes they and grounded part insulation.At present the insulator on the high-tension line have that creepage distance is short, the husky erosion of the easy wind and rain dirt of insulator and cause the pollution flashover phenomenon to take place, bring very big harm to high-tension line.
Summary of the invention
The purpose of the utility model provides a kind of high-tension line resistant cap and pin insulator, and it can increase creepage distance, improves pollution flashover voltage, has guaranteed the normal operation of high-tension line.
In order to solve the existing problem of background technology; The utility model is taked following technical scheme: it comprises chapeau de fer 1, insulating porcelain piece 3, steel pin 5, metal ring plate 6 and anti-pollution layer 7; Chapeau de fer 1 is bonding through cement gel and insulating porcelain piece 3 heads; Insulating porcelain piece 3 internal diameters are bonding through cement gel and steel pin 5, and metal ring plate 6 internal diameters match with chapeau de fer 1 bottom external diameter, and last full skirt 2 outer surfaces of insulating porcelain piece 3 scribble anti-pollution layer 7.
Described metal ring plate 6 upper and lower surfaces and lateral surface are provided with silicon rubber.
Last full skirt 2 external diameters of the insulating porcelain piece 3 in the utility model can increase creepage distances through metal ring plate 6 greater than following full skirt 4 external diameters, and anti-pollution layer 7 has good anti-soil effect.
The utility model can increase creepage distance, improves pollution flashover voltage, has guaranteed the normal operation of high-tension line.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
With reference to Fig. 1; This embodiment is taked following technical scheme: it comprises chapeau de fer 1, insulating porcelain piece 3, steel pin 5, metal ring plate 6 and anti-pollution layer 7; Chapeau de fer 1 is bonding through cement gel and insulating porcelain piece 3 heads; Insulating porcelain piece 3 internal diameters are bonding through cement gel and steel pin 5, and metal ring plate 6 internal diameters match with chapeau de fer 1 bottom external diameter, and last full skirt 2 outer surfaces of insulating porcelain piece 3 scribble anti-pollution layer 7.
Described metal ring plate 6 upper and lower surfaces and lateral surface are provided with silicon rubber.
Last full skirt 2 external diameters of the insulating porcelain piece 3 in this embodiment can increase creepage distances through metal ring plate 6 greater than following full skirt 4 external diameters, and anti-pollution layer 7 has good anti-soil effect.
This embodiment can increase creepage distance, improves pollution flashover voltage, has guaranteed the normal operation of high-tension line.
