Abstract
The utility model discloses a kind of binodal Combined high-strength post composite insulator, the plug comprising upper bracket and undersetting and be fixed between upper bracket and undersetting, described plug sidewall is provided with full skirt, and described plug is upper and lower two, and described upper and lower two plugs are connected by ring flange.The utility model has the advantages that mechanical strength is high, lightweight, manufacture craft simple, anti-soil sudden strain of a muscle ability is high, can be widely used in electric power electric field.
Description
Technical field
The utility model relates to electric power electric field, particularly relates to a kind of binodal Combined high-strength post composite insulator.
Background technology
Along with day by day increasing the weight of of environmental pollution, station insulator pollution flashover accident increases gradually, especially solid core post insulator.A lot of transformer station selects little due to original post insulator creepage distance, is difficult to meet existing requirement.Meanwhile, along with the raising of transmission voltage grade, the electric discharge problem of staining of circuit external insulation is more and more serious, uses high voltage withstanding, high mechanical properties, resistance to filth, ageing-resistant high-performance post insulator to become a kind of trend.But voltage levels post insulator height is long, mechanical bend insufficient strength can be caused large.The existing porcelain insulator adopted is difficult to meeting the market requirement because its weight is large, anti-pollution characteristic is poor, price is high.
Utility model content
The purpose of this utility model is the deficiency in order to overcome above-mentioned background technology, provides a kind of binodal Combined high-strength post composite insulator, has the advantages that mechanical strength is high, lightweight, manufacture craft simple, anti-soil sudden strain of a muscle ability is high.
A kind of binodal Combined high-strength post composite insulator that the utility model provides, the plug comprising upper bracket and undersetting and be fixed between upper bracket and undersetting, described plug sidewall is provided with full skirt, described plug comprises plug and lower plug, and described upper plug is connected by ring flange with lower plug.
In technique scheme, described upper plug is less than lower plug size, and the full skirt of described upper plug is less than the full skirt size of lower plug.
In technique scheme, the ring flange be connected between described upper plug and lower plug is connected by bolt, and described bolt is provided with sheath.
In technique scheme, described full skirt adopts the structure of size interlaced arrangement.
The utility model binodal Combined high-strength post composite insulator, has following beneficial effect: after two joint plugs difference are shaping, plug injects full skirt, assembled by the ring flanges on two joint plugs by bolt.The overall dimension of a joint plug and full skirt is less above, and a grade can fall in diameter of mandrel, can meet larger mechanical bend requirement of strength.
Binodal Combined high-strength post composite insulator has and reduces composite insulator height, improve composite insulator mechanical strength, technique simpler, lightweight, the non-homogeneous advantages such as flashover of drenching with rain can be solved.When same structure height, the mechanical strength of binodal Combined high-strength post composite insulator is larger, be more convenient for dismounting and transport.
Simultaneously, binodal Combined high-strength post composite insulator surface also has good hydrophobicity and molecular migration, the anti-soil that can significantly improve insulator dodges ability, thus improve the reliability of system cloud gray model, be the preferred plan solving electric power system antifouling work problem, possess skills and clear superiority economically.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model binodal Combined high-strength post composite insulator.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.
See Fig. 1, the utility model binodal Combined high-strength post composite insulator, the plug 2 comprising upper bracket 1 and undersetting 7 and be fixed between upper bracket 1 and undersetting 7, described plug 2 sidewall is provided with full skirt 3, described plug 2 comprises plug 2.1 and lower plug 2.2, described in comprise plug 2.1 and be connected by ring flange 4 with lower plug 2.2.
Described upper plug 2.1 is less than lower plug 2.2 size, and the full skirt 3 of described upper plug 2.1 is less than full skirt 3 size of lower plug 2.2.
The ring flange 4 be connected between described upper plug 2.1 and lower plug 2.2 is connected by bolt 5, and described bolt 5 is provided with sheath 6.
Described full skirt 3 adopts the structure of size interlaced arrangement.
Composite insulator adopts silicon rubber to make, and also comprises lower flange 4, upper bracket 1, undersetting 7, plug 2, full skirt 3 and sheath 6 and forms.
The epoxy glass fiber of plug 2 material employing high temperature-resistant acid-resistant pulls out and draws rod.Full skirt 3 adopts high temperature vulcanized glue.Consider product electric pressure, structure height, full skirt 3 arranges that the room for maneuver is less, and therefore to adopt open size to replace umbellate form comparatively suitable for full skirt 3 structure.
In order to improve the adhesive property at interface, plug 2 is polished and is adopted sand blasting process, and coupling agent adopts YGO1401 coupling agent.Post composite insulator with electric pressure product its height and flange size and profile variation many, for adapting to various flange, be convenient to injection moulding, this product joins annex technique after adopting and first injecting umbrella cover, umbrella cover is general injection, press-connection machine crimping controlled while of the bigbore displacement of crimping employing DJY6000 model and pressure, last end high temperature silicone rubber seals.
After two joint products difference are shaping, assembled by bolt 5.During transport, two joints can separately transport, and in-site installation combines.A general joint overall dimension is above less, and a grade can fall in plug 2 diameter, just can meet identical mechanical bend requirement of strength.
Obviously, those skilled in the art can carry out various change and modification to the utility model and not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of the utility model claim and equivalent technologies thereof, then the utility model is also intended to comprise these change and modification.
The content be not described in detail in this specification belongs to the known prior art of professional and technical personnel in the field.
