Abstract

The utility model discloses a kind of composite rod insulators for having and resisting ablation and brittle failure ability, the outside that end metal fitting glass epoxy plug is set at the both ends of glass epoxy resin plug has silicon rubber cluster parachute housing, it is characterized in that there is the one layer of insulating materials of resistance to ablation liner with the umbrella wing between glass epoxy resin plug and silicon rubber cluster parachute housing, the insulating materials of the resistance to ablation liner with the umbrella wing wraps up the connecting portion of end metal fitting and glass epoxy resin plug to both ends extension, the both ends of silicon rubber cluster parachute housing, which also upwardly extend, wraps up the extension of the insulating materials of the resistance to ablation liner with the umbrella wing.Its advantage is to employ new structure, the gold utensil at insulator both ends and plug are set with, the protective layer of anti-brittle failure and ablation with the umbrella wing extends beyond gold utensil and plug connecting portion, connecting portion is fully wrapped around, so as to thoroughly prevent brittle failure and ablation failure caused by the problems such as micro-strain local caused by pulling force and other reasons and crackle.

Description

It is a kind of that there is the composite rod insulator for resisting ablation and brittle failure ability

Technical field

The utility model belongs to the parts used on electric power power transmission and transformation line, is specifically that one kind has resistance ablation With the composite rod insulator of brittle failure ability.

Background technology

For the stick or post insulator used at present, one kind as disclosed in Chinese patent 201320519578.9 With the bar-shaped composite insulator for being seamlessly connected protective layer.With the preferable ability for resisting ablation and brittle failure, still, at us Practical application in find, this structure is current when being used for major diameter, there is because stretching resistance is insufficient and both ends gold utensil with Local micro-strain and blind crack are generated between protective layer, and causes easily to generate brittle failure in cold season application, other Time easily generates the failures such as the ablation of part, in order to improve this situation, it is proposed that the goal of the invention of the utility model.

Invention content

The goal of the invention of the utility model is insufficient existing for above-mentioned stick or cylindricality composite insulator in order to overcome And put forward.A kind of composite rod insulator for having and resisting ablation and brittle failure ability is provided.

The technical solution of the utility model is achieved in that this has the compound bar for resisting ablation and brittle failure ability Shape insulator, the outside that end metal fitting (1) glass epoxy plug is set at the both ends of glass epoxy resin plug (2) have silicon Rubber cluster parachute housing (4), it is characterised in that there is one layer of band umbrella between glass epoxy resin plug and silicon rubber cluster parachute housing The insulating materials of the resistance to ablation liner (3) of the wing, the insulating materials of the resistance to ablation liner with the umbrella wing extend to both ends by end metal fitting It is wrapped up with the connecting portion of glass epoxy resin plug, the both ends of silicon rubber cluster parachute housing are also upwardly extended the resistance to burning with the umbrella wing Lose the extension package of insulating materials liner.

The beneficial of the utility model has the technical effect that：New structure is employed, by the gold utensil and plug at insulator both ends Suit, the protective layer for resisting brittle failure and ablation are more than and cover the connecting portion of gold utensil and plug, meanwhile, the extension of silicon rubber cluster parachute To being more than to resist brittle failure and the protective layer of ablation and the connecting portion of both ends gold utensil, and it is fully wrapped around to connect position, so as to Thoroughly prevented due to brittle failure caused by the problems such as micro-strain local caused by pulling force and other reasons and blind crack and Ablation failure.The insulating materials of resistance to ablation with the umbrella wing increases its rigidity using umbrella skirt construction, insulator strength can be made significantly to carry Height, compared to silicone rubber material full skirt more resistant to maintenance when the external impacts such as trample, in the insulating materials of the resistance to ablation umbrella with the umbrella wing One layer of silicon rubber of skirt outer wrapping makes it have good high- and low-temperature resistance, and hydrophobicity and migration of hydrophobicity make its resistance to pollution flashover It can greatly improve, many excellent properties such as anti creepage trace and anti-galvanic corrosion damage property make it have good application value.

Description of the drawings

Fig. 1 is the vertical section structure schematic diagram of the hollow plug structure composite insulator of the utility model, and Fig. 2 is this practicality The vertical section structure schematic diagram of novel solid mandrel structure composite insulator, Fig. 3 are that the amplification of structure at the A of Fig. 1 and Fig. 2 is shown It is intended to.Serial number in attached drawing：1st, end metal fitting, 2, glass epoxy resin plug, 3, in the insulating materials of resistance to ablation with the umbrella wing Lining, 4, silicon rubber cluster parachute housing.

Specific embodiment

The structure and use of the utility model is described in detail in the embodiment provided in below in conjunction with the accompanying drawings.Reference Attached drawing, Fig. 1 and Fig. 3 are a kind of embodiments of hollow core rod structure of the utility model, are suitble to larger diameter stick or cylindricality Insulator uses.Fig. 2 and Fig. 3 is the embodiment of another solid construction plug of the utility model.This kind, which has, resists ablation With the composite rod insulator of brittle failure ability, end metal fitting (1) glass ring is set at the both ends of glass epoxy resin plug (2) The outside of oxygen plug has silicon rubber cluster parachute housing (4), it is characterised in that outside glass epoxy resin plug and silicon rubber cluster parachute Between set have the one layer of insulating materials of resistance to ablation liner (3) with the umbrella wing, the insulating materials of the resistance to ablation liner with the umbrella wing to The connecting portion of end metal fitting and glass epoxy resin plug is wrapped up in both ends extension, and the both ends of silicon rubber cluster parachute housing are also prolonged upwards It stretches and wraps up the extension of the insulating materials of the resistance to ablation liner with the umbrella wing.The insulating materials of resistance to ablation can use such as：Quartz Sand (powder), ceramic powder, glass dust etc. have some strength and the material of insulation performance.

Such structure, it is local micro- when to generate between the gold utensil at both ends and plug by larger pulling force in use When small deformation or subtle crackle, the insulating materials of the resistance to ablation liner with the umbrella wing for being wrapped in outside can also generate therewith, but It is that the extension of external silicon rubber cluster parachute is fully wrapped around by its, without these crackles and deformation is made to be exposed in air, So as to avoid because crackle and deformation are exposed to the brittle failure and ablation that are generated under external environmental condition.It should with great promote With value.
