Abstract
The utility model provides an unbreakable type suspension insulator for a high-voltage line. The utility model is composed of a mandrel, insulating umbrella covers which are arranged at the outer side of the mandrel, and accessories which are arranged at the two end parts of the mandrel. The utility model is characterized in that spacer sleeves are arranged among insulating umbrella covers or between the insulating umbrella covers and the accessories, and sheaths are arranged between the mandrel and the insulating umbrella covers or the spacer sleeves. The utility model fully utilizes and effectively combines the characteristics of difficult damage, good toughness, light weight, etc. of the mandrel of an organic composite insulator, and the properties of superior ageing resistant performance, and low cost of a porcelain umbrella cover, and the sealing performance of products can be ensured. Therefore, the insulator has the characteristics of portability, no aging, easy installation, etc., and is not easy to damage. The utility model is a new generation ideal suspension insulator.
Description
The utility model relates to a kind of high-tension line insulator, particularly a kind of high-tension line suspension insulator that can not puncture.
High-tension line is broadly divided into two classes with the insulation component of the suspension insulator amount of being to use maximum, existing this series products, and a class is the glass insulation substring, its Heavy Weight, and can increase or reduce string length according to the needs of electric pressure; Another kind of is that it is in light weight at the organic composite insulator of the outer rim socket silicon rubber umbrella cover of fiber reinforced plastics rod, and is once made the length of regulation by producer by the difference of electric pressure.Though the former is adjustable length in installing and using process, but glass insulator is frangible, explosive element, its useful life is shorter, and weight is heavier, the utilance that the former latter in recent years is the lighter organic composite insulator of weight is higher, but because its price is higher relatively, and length is nonadjustable in installing and using process, still bring many inconvenience to the user, therefore, in the urban distribution network or upgrade of rural power grids of low-voltage grade, still select for use price low, electrical property is unsettled can puncture type porcelain insulator, existing in addition insulator is can the puncture type, needs regularly or aperiodically detect its null value, and it is frequent to cause power failure etc., therefore, be necessary further improvement is done in existing insulation.
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of stable performance is provided, and is simple in structure, adjustable length, the puncture-proof suspension insulator of long service life.
The utility model is realized by following technical proposal: it is by plug, the annex formation of being located at the insulation umbrella cover of mandrel outer and being located at both ends, it is characterized in that being provided with separation sleeve between the insulation umbrella cover or between insulation umbrella cover and the annex, and between plug and insulation umbrella cover or separation sleeve, be provided with sheath.The perimeter wall of the shape of described separation sleeve and silicon rubber plug adapts, and is placed on the plug perimeter wall, makes it alternate setting with the porcelain insulating umbrella cover, so that according to any length that extends or shorten insulator string of on-the-spot needs.Described sheath shape and plug outer rim adapt, and directly are placed on the plug, are used to remedy the deficiencies such as sealing effectiveness difference that separation sleeve brings with the insulation alternate setting of umbrella cover, to guarantee the sealing property of product.
The utility model compared with prior art has following advantage and effect: owing to be provided with the separation sleeve alternate with the porcelain insulating umbrella cover in the plug outer rim; and the protective sleeve that between plug and separation sleeve and porcelain insulating umbrella cover, is provided with again; it is not perishable to have made full use of core rod of organic composite insulator; good toughness; characteristics such as in light weight; and ageing-resistant performance is superior; the porcelain umbrella cover that cost is low; effective comprehensively both characteristics; and the sealing property of assurance product; therefore; it is light that this insulator is had; not aging; not fragile; characteristics such as easy for installation; use is in high-grade voltage and extra-high pressure occasion; the insulator string that can extend arbitrarily as required, real be of new generation comparatively desirable suspension insulator.
Fig. 1 is the structural representation of the utility model.
Below in conjunction with accompanying drawing the utility model is described further, is not limited to this but hold within the utility model.
Among the figure, 1 is the ball-and-socket annex, is arranged at the insulator two ends, and 2 is separation sleeve, makes with rubber, and 3 is the porcelain insulating umbrella cover, and 4 is sheath, makes with silicon rubber, and 5 is the silicon rubber plug, and 6 is the bulb metal-ware.
Claims (3)
1, a kind of puncture-proof high-tension line suspension insulator, by plug, the annex formation of being located at the insulation umbrella cover of mandrel outer and being located at both ends, it is characterized in that being provided with separation sleeve between the insulation umbrella cover or between insulation umbrella cover and the annex, and between plug and insulation umbrella cover or separation sleeve, be provided with sheath.
2, insulator according to claim 1 is characterized in that the shape of described separation sleeve and the perimeter wall of silicon rubber plug adapt, and is placed on the plug perimeter wall.
3, insulator according to claim 1 is characterized in that described sheath shape and plug outer rim adapt, and directly are placed on the plug.
