The utility model discloses lead to under same structrual height parameter, has not only practiced thrift manufacturing cost, adopt mutually unidimensional full skirt design time in addition, the utility model discloses the creepage distance who obtains than present composite insulator will grow, therefore, excellent insulating properties more has, and the price / performance ratio is higher.

Description

A kind of Novel combined insulator

Technical field

The utility model relates to a kind of composite insulator.

Background technology

Pillar (pin type) composite insulator (as shown in Figure 5, needle type composite insulator as shown in Figure 6 for post composite insulator) is used in electric power system the basic insulating part playing supporting and isolated insulation effect.Its traditional structure is generally such: two ends are metal support connector (in 2, Fig. 6 in Fig. 52,4), rises and connects and fixation; There is an insulation mandrel 1 inside, provides enough interior dielectric strengths and transmits external force and bear the effect of opposing insulator outside destroy; Outside is designed to resist the silicon rubber insulation umbrella cover 3 of the insulation breakdown from electric power system fluctuation voltage and nature lightning surge voltage, protects insulation mandrel unlikely inefficacy from atmospheric corrosion simultaneously.

In the manufacturing cost forming conventional column (pin type) composite insulator, the purchase cost of the metal support connector at two ends generally will account for about 1/3 to 1/2 of whole insulator manufacturing cost.For reducing insulator production cost, to metal support stud connector design, ensureing to adopt the structure reducing metal consumption under insulator bonding strength prerequisite as far as possible.But under structures shape cost conditions, its cost reduce also have one very large restricted.

Utility model content

Technical problem to be solved in the utility model is, a kind of new composite insulator is provided, the supporting connecting piece of this composite insulator at least one end adopts SMC or DMC rolled-up stock, with alternative metals supporting connecting piece, and be fixed on insulation mandrel by specific metal transfer adapter sleeve, under the prerequisite that intensity ensures, greatly reduce the cost of composite insulator.

Novel combined insulator of the present utility model, comprise the skeleton be made up of with the supporting connecting piece being positioned at insulation mandrel two ends insulation mandrel, silicon rubber umbrella is pressed with at this skeleton external mold, this composite insulator has at least the supporting connecting piece of one end to be SMC or DMC rolled-up stock, and the metal transfer adapter sleeve that this SMC or DMC rolled-up stock is provided with some grooves by surface is fixedly connected with insulation mandrel.

Further, the metal transfer adapter sleeve that described surface is provided with some grooves is fixed in the termination of insulation mandrel through crimping, SMC or DMC rolled-up stock by raw material through hot melt curing mold pressing in the surface of metal transfer adapter sleeve and the termination of coated insulation plug.

Further, described SMC or DMC rolled-up stock entirety is coated in silicon rubber umbrella.

Wherein, described SMC or DMC rolled-up stock is SMC or DMC flange, and is respectively provided with one at insulation mandrel two ends.

Further, described SMC or DMC flange is also embedded with metal nuts inserts.

Described SMC or DMC rolled-up stock can also be SMC or DMC pin cap, and this SMC or DMC pin cap is arranged at one end of insulation mandrel, is arranged with iron pin at the other end of insulation mandrel.

Further, described iron pin front end is coated in silicon rubber umbrella.

SMC(sheet molding compound, Sheetmoldingcompound), and DMC(BMC, Doughmoldingcompounds), all there are excellent electrical insulation capability, mechanical performance, thermal endurance and resistance to chemical corrosion etc., the requirement of insulator to performance can be met, and easy-formation.

Given this, the utility model, by the metal support connector of composite insulator at least one end is replaced with SMC or DMC rolled-up stock, at utmost reduces the consumption of metal material, greatly reduces the manufacturing cost of composite insulator.The metal transfer adapter sleeve that SMC or DMC rolled-up stock is provided with some grooves by surface is fixedly connected with insulation mandrel, ensure that the bonding strength of insulation mandrel and SMC or DMC rolled-up stock.Under same structure height parameter, not only saved manufacturing cost, and when adopting the full skirt of same size to design, the creepage distance that the utility model obtains than existing composite insulator is long, thus, have more excellent insulation property, cost performance is higher.
