Abstract
The utility model discloses a rubber creepage extender disc type suspension insulator. The suspension insulator comprises an umbrella slot located on an upper part and the creepage extender located on a lower part. The umbrella slot is a ceramic or glass material. The creepage extender located on the lower part is partially or completely made of a rubber material. By using the rubber creepage extender disc type suspension insulator provided in the utility model, the ceramic/glass and rubber materials are complexly used; a mechanical property of the insulator is guaranteed and simultaneously a stain resistance of the insulator is guaranteed too.
Description
Technical field
The utility model relates to cap and pin insulator, relates in particular to the cap and pin insulator that a kind of creeping-increasing skirt adopts the rubber material.
Background technology
The plate-shaped suspension type insulator is mainly used in the insulation and the fixing cord that supply in the high voltage overhead electric line and uses.Traditional cap and pin insulator adopts pottery or glass material to process; Its quality is heavier; Anti-pollution characteristic is also poor, and to the insulator that the composite material of this proposition is processed, its anti-pollution characteristic has obtained bigger improvement; But the mechanical endurance of composite insulator is far away from the ceramic/glass insulator, and also suffers damage easily in the operation operation or when safeguarding.
The utility model content
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the cap and pin insulator that the utility model provides a kind of creeping-increasing skirt to adopt the rubber material when guaranteeing the insulator mechanical performance, improves the resistance to soiling of insulator, and reduces its weight.
Technical scheme: for solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
Rubber creeping-increasing skirt cap and pin insulator comprises superposed umbrella disk and the creeping-increasing skirt that is positioned at the bottom, and said umbrella disk is pottery or glass material, and the bottom creeping-increasing skirt partly or entirely is rubber material or other insulation material.
Said structure has been avoided traditional cap and pin insulator all to adopt the ceramic/glass material or has all been adopted the deficiency of composite material, compound ceramic/glass and the elastomeric material of having used.Because the top umbrella disk still uses the ceramic/glass material, has guaranteed its mechanical performance and ageing-resistant performance; Simultaneously, when the cap and pin insulator transportation, installation, maintenance, the people that can on umbrella disk, stand, similar with traditional ceramics/glass insulator, safeguard very convenient.Because creeping-increasing skirt adopts elastomeric material, has guaranteed its anti-pollution characteristic; Simultaneously, the elastomeric material light weight makes the relative traditional ceramics of product quality/glass insulator descend (can up to 30%), reduces the cost of shaft tower.
For make ceramic/glass surface hydrophobicity performance and rubber-like seemingly, can be coated with room temperature or high temperature vulcanizate in the outside of umbrella disk, improve its resistance to soiling.
This cap and pin insulator can be bell jar type beveled structure, and its outside umbrella cover structure constitutes umbrella disk, and inboard umbrella rib structure constitutes creeping-increasing skirt; Can umbrella rib structure all be adopted the rubber material; Can also be provided with the outward extending umbrella wing in the end of umbrella rib structure, the umbrella wing is all adopted the rubber material.
This cap and pin insulator can be two umbrella disk beveled structures, and its upper strata umbrella cover structure constitutes umbrella disk, and lower floor's umbrella cover structure constitutes creeping-increasing skirt; Can lower floor's umbrella cover structure all be adopted the rubber material.
Beneficial effect: the rubber creeping-increasing skirt cap and pin insulator that the utility model provides, compound ceramic/glass and the elastomeric material of having used guaranteed the resistance to soiling of insulator when having guaranteed the insulator mechanical performance.

Fig. 2 is second kind of structural representation of the utility model;
Fig. 3 is the third structural representation of the utility model;
Fig. 4 is the 4th kind of structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
Rubber creeping-increasing skirt cap and pin insulator comprises superposed umbrella disk and the creeping-increasing skirt that is positioned at the bottom, and said umbrella disk is pottery or glass material, and the bottom creeping-increasing skirt partly or entirely is the rubber material; In order to increase the resistance to soiling of umbrella disk, can be coated with room temperature or high temperature vulcanizate in the umbrella disk outside.
This cap and pin insulator also goes for two umbrella disk beveled structures as shown in Figure 4 applicable to like Fig. 1, Fig. 2, bell jar type beveled structure shown in Figure 3.
For bell jar type beveled structure, its outside umbrella cover structure 1 constitutes umbrella disk, and inboard umbrella rib structure 2 constitutes creeping-increasing skirt; For two umbrella disk beveled structures, its upper strata umbrella cover structure 4 constitutes umbrella disk, and lower floor's umbrella cover structure 5 constitutes creeping-increasing skirt.
Bell jar type beveled structure as shown in Figure 1, its inboard umbrella rib structure 2 adopts the rubber material; Like Fig. 2, bell jar type beveled structure shown in Figure 3, be provided with the outward extending umbrella wing 3 in the end of umbrella rib structure 2, the said umbrella wing 3 adopts the rubber materials; Two umbrella disk beveled structures as shown in Figure 4, its lower floor's umbrella cover structure 5 adopts the rubber material.
The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.
