Abstract
The utility model discloses a kind of composite rod insulators that can resist ablation and brittle failure, 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 between glass epoxy resin plug and silicon rubber cluster parachute housing, the insulating materials of the resistance to ablation liner wraps up the connecting portion of end metal fitting and glass epoxy resin plug to both ends extension, and 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.Its advantage is to be set with the gold utensil at insulator both ends and plug, resist brittle failure and the protective layer covering gold utensil of ablation and the connecting portion of plug, silicon rubber cluster parachute extends beyond the connecting portion, and it is fully wrapped around to connect position, so as to thoroughly prevent due to brittle failure and ablation failure caused by the problems such as micro-strain local caused by pulling force and other reasons and blind crack.
Description
Technical field
The utility model belongs to the parts used on electric power power transmission and transformation line, is specifically that one kind can resist ablation
With the composite rod insulator of brittle failure.
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 that can resist ablation and brittle failure is provided.
The technical solution of the utility model is achieved in that this can resist ablation and the composite rod of brittle failure is exhausted
Edge, 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 exhausted with one layer of resistance to ablation between glass epoxy resin plug and silicon rubber cluster parachute housing
Edge material liner (3), the insulating materials of the resistance to ablation liner to both ends extension by end metal fitting and glass epoxy resin plug
Connecting portion wraps up, and 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.
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 the connecting portion of protective layer with both ends gold utensil of resisting brittle failure and ablation, 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.
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, the insulating materials of resistance to ablation liner, 4, silicon rubber
Glue 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 can resist ablation
With the composite rod insulator of brittle failure, end metal fitting (1) glass epoxy core is set at the both ends of glass epoxy resin plug (2)
The outside of stick has silicon rubber cluster parachute housing (4), it is characterised in that glass epoxy resin plug and silicon rubber cluster parachute housing it
Between there is the one layer of insulating materials of resistance to ablation liner (3), the insulating materials of the resistance to ablation liner to both ends extension by end metal fitting and
The connecting portion package of glass epoxy resin plug, the both ends of silicon rubber cluster parachute housing are also upwardly extended the insulating materials of resistance to ablation
The extension package of liner.The insulating materials of resistance to ablation can use such as：Quartz sand (powder), ceramic powder, glass dust etc. have one
Determine the material of intensity and 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, being wrapped in the insulating materials of the resistance to ablation liner of outside can also generate therewith, still, outside
Silicon rubber cluster parachute extension its is fully wrapped around, 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 generated under external environmental condition.With great application value.
