Abstract
An outside insulation cover of synthetic insulator and high-pressure synthetic insulator is umbrella skirt-shaped, the concave of umbrella skirt faces adown, a plurality of annular strengthening ribs are arranged at the brim and middle of the concave. The technology parting line of the outside insulation cover adopts transverse setup; the parting line of the high-pressure synthetic insulator is arranged at the strengthening ribs which are arranged at the fringe of the umbrella skirt. More than three supporting points used for fixing the core rod, which are in the fillet of the outside insulation cover, are evenly arranged at each segment of each umbrella set. Since the outside insulation cover and the insulator are provided with the capabilities such as a good water resistance, tracking resistance, electrical erosion resistant, anti-moisture flashover, anti-dirt flashover and so on, therefore the surface of the umbrella skirt is not easy to produce creepage flashover when the umbrella skirt is in a bad weather such as fog, humidity and freezing weather; moreover the utility model has other advantages of: high mechanical strength; without edge collapse; anti-aging; slitting-resistant; safe and reliable.
Description
Technical field
The utility model relates to the external insulation sleeve and the high-pressure synthetic isolator of high-pressure synthetic isolator, is meant electric locomotive roof organic composite material insulator external insulation sleeve and high-pressure synthetic isolator especially.
Background technology
Along with the development of modern electric power industry mesohigh technology of transmission of electricity, need the voltage of use more and more higher; Electric locomotive is also towards high-power, high-speed and stride developing by leaps and bounds of long-distance running technology in addition.Because the pollution grows worse of air environment, traditional ceramic insulator is more and more inapplicable aspect the reliability of electric insulating quality and mechanical strength.Freeze, rain, foggy weather is waited and the insulator surface laying dust after, accidents such as the fried bottle that often occurs, electric leakage punctures, fracture are very big to ultra-high-tension power transmission line and safety of railway transportation threat.Domestic in recent years ultra-high-tension power transmission line composite material insulator and the roof composite material insulator that occurs in succession, though improving that its anti-soil dodges and wet dodge technical has a very quantum jump, but existing insulation sleeve adopts simple umbrella skirt construction, its full skirt mechanical strength is low, after having used a period of time, because suffered external force is very big in the environment for use, environment is abominable, situation is worn out, tears on the easy limit of collapsing of existing external insulation umbrella cover, causes external insulation sleeve to lose efficacy.The external insulation sleeve technology parting line of existing composite material insulator vertically is provided with along full skirt simultaneously, the external insulation sleeve that adopts this mode to carry out the branch mould is easy to generate electric leakage flashover phenomenon along parting line, thereby the moisture-resistant of insulator is dodged and the pollution flashover reliability decrease, cause the insulator cisco unity malfunction, even insulator was lost efficacy.
Summary of the invention
The purpose of this utility model is to provide on a kind of structure mechanical strength good, and anti-soil dodges and wets that the sudden strain of a muscle ability is strong, creep distance is big, technology failure-free high-pressure synthetic isolator external insulation sleeve and high-pressure synthetic isolator.
The high-pressure synthetic isolator external insulation sleeve of realizing the utility model purpose adopts latericeous high-temperature silicon disulfide rubber to make the full skirt shape, and the full skirt concave surface is provided with ring stiffener down on concave surface.Adopt the intensity of the external insulation sleeve of reinforced rib to strengthen, but actv. prevents to collapse the limit, tear phenomenon.Increased the length of insulation path simultaneously, made the insulating power of external insulation sleeve better.
As improvement of the present utility model, the reinforced rib of external insulation umbrella cover concave surface is that the edge and the centre that are located at concave surface all have ring stiffener, has both guaranteed mechanical strength preferably, and is rational in infrastructure, makes the attractive in appearance of external insulation sleeve again.
In order to solve along the creepage shortcoming of parting line, the technology parting line of external insulation sleeve adopts horizontally set.
As improvement, the position of external insulation sleeve parting line is arranged on the reinforced rib at full skirt edge.Set up parting line at the edge, can effectively solve creepage problem, conveniently stripped again.
In order to make the external insulation sleeve stationary core rod reliable, guarantee between plug and the external insulation sleeve concentricity, make the perfusion space even, on the interior circle of external insulation sleeve, be provided with a plurality of strong points of stationary core rod.
As improvement, for the strong point of stationary core rod, every section of each umbrella cover all more than three or three, and the center of circle of plug is overlapped with the center of circle of external insulation sleeve, guarantee with one heart.
A kind of high-pressure synthetic isolator comprises formations such as interior insulation mandrel, external insulation sleeve, and external insulation sleeve adopts latericeous high-temperature silicon disulfide rubber to make the full skirt shape, and the full skirt concave surface is provided with ring stiffener down on concave surface.
As improvement, the reinforced rib of external insulation sleeve concave surface is that the edge and the centre that are located at concave surface all have ring stiffener.
As improvement, the technology parting line of external insulation sleeve adopts horizontally set.The position of external insulation sleeve parting line is arranged on the reinforced rib at full skirt edge.
As further improvement, every intersegmental several strong points that are provided with stationary core rod of each umbrella cover on the interior circle of external insulation sleeve, each umbrella cover of the strong point of stationary core rod is more than three or three.
Adopt insulator external insulation sleeve of the present utility model and insulator, have good hydrophobic nature, anti creepage trace, anti-galvanic corrosion, moisture-resistant sudden strain of a muscle and anti-soil and dodge ability, when dense fog, humidity, freezing weather, the full skirt surface is difficult for the electric leakage flashover, and the mechanical strength height, the good advantage of limit, antiageing and the anti tear of not collapsing.
Description of drawings
Fig. 1 is the generalized section of the external insulation sleeve and the insulator of composite insulator.
Specific embodiment
As shown in Figure 1, the external insulation sleeve 2 of high-pressure synthetic isolator makes the external shed shape for high-temperature silicon disulfide rubber, and the full skirt concave surface has reinforced rib 3 at the edge of concave surface down, and all there is ring stiffener 4 centre.The technology parting line 5 of the external insulation sleeve 2 of high-pressure synthetic isolator adopts horizontally set, is arranged on the reinforced rib 3 at full skirt edge.In order to make external insulation sleeve 2 stationary core rods 1 reliable, the concentricity of all even plug 1 in the space between assurance high-pressure synthetic isolator plug 1 and the external insulation sleeve 2 and external insulation sleeve 2, at the interior circle of external insulation sleeve 2, each umbrella cover layer is equipped with four strong points 6 of stationary core rod 1.Plug 1 is packed into behind the external insulation sleeve 2, middle perfusion silica gel seal bonding firmly.Adopt insulator external insulation sleeve of the present utility model and insulator, have good hydrophobic nature, anti creepage trace, anti-galvanic corrosion, moisture-resistant sudden strain of a muscle and anti-soil and dodge ability, when dense fog, humidity, freezing weather, the full skirt surface is difficult for the electric leakage flashover, and mechanical strength height, limit, antiageing and the anti tear of not collapsing is good, safe and reliable advantage.
