Description
Affiliated technical field:
The present invention relates to power transmission and transformation protection equipment technical field, be specifically related to a kind of combined coat lightning arrester.
Background technology:
At present, both at home and abroad lightning arrester is common two kinds of full porcelain coat lightning arrester and full polymeric housed metal oxide arresters, and these two kinds of lightning arresters all exist shortcoming separately: full porcelain coat lightning arrester exists that volume is big, weight is big, installation and transportation are inconvenient and the problem of the dirty poor performance of resistant; And full polymeric housed metal oxide arrester exists the dissatisfactory problem of mechanical strength.These two problems also are not very outstanding under the inferior grade voltage conditions, but use can have a strong impact on its serviceability under the voltage conditions of higher level, to the raising formation restriction of electric pressure.
Summary of the invention:
The present invention will provide a kind of combined coat lightning arrester, the volume that not only will overcome full porcelain coat lightning arrester existence is big, weight is big, installation and transportation are inconvenient and the problem of the dirty poor performance of resistant, also will overcome the dissatisfactory problem of mechanical strength that full polymeric housed metal oxide arrester exists simultaneously.
For overcoming the problem that prior art exists, technical solution of the present invention is: a kind of combined coat lightning arrester, comprise a joint or number joint lightning arrester unit, comprise insulating coating and flange 4 on the lightning arrester unit, its special character is: described insulating coating is two-layer, and internal layer is the insulating cylinder 3 of ceramic material, and skin is the umbrella cover 1 of organic composite material, described insulating cylinder 3 outer walls are matsurface, are adhesive linkage 2 between the matsurface of insulating cylinder 3 outer walls and the umbrella cover 1 of organic composite material.
Adopt mucilage binding to connect between above-mentioned insulating cylinder 3 and the flange 4.
The present invention is not simply both to be superposeed when overcoming the problem that full porcelain coat lightning arrester and full polymeric housed metal oxide arrester exist separately, shows that by various data this is invented on every performance and all improves a lot.Compared with prior art, advantage of the present utility model is mainly reflected in following several aspect:
1, volume is little, in light weight: adopt porcelain insulating cylinder and organic composite material umbrella cover to synthesize the insulating coating of lightning arrester, with full porcelain coat lightning arrester mutually specific volume reduce weight saving, in height also decrease simultaneously, than the easier assembling of full porcelain coat lightning arrester, transportation and installation.Product of the present invention is under equal electric pressure condition, and for example the lightning arrester of 1000kV grade adopts the present invention, low about 1 meter of the full porcelain coat lightning arrester of its aspect ratio, and weight saving is about 10%～15%, and installation and transportation are more convenient.
2, mechanical strength is good: at first made full use of the high mechanical properties of ceramic material among the present invention and the material of insulating cylinder is decided to be porcelain, secondly adopted the mucilage binding to connect between insulating cylinder and the flange, further guaranteed the lightning arrester overall mechanical strength.For example, the lightning arrester of 1000kV grade, the bending strength of lightning arrester porcelain shell can reach 150kN.m, and is suitable with the intensity of the full porcelain coat lightning arrester of ad eundem.
3, hydrophobicity performance is good, anti-pollution characteristic is strong: made full use of the advantage that the organic composite material hydrophobicity performance is good, anti-pollution characteristic is strong, gradation for surface pollution can reach 0.06mg/cm
2
4, the insulating coating of lightning arrester has good external insulation performance in this structure: experimental data shows that the external insulation performance of lightning arrester can reach: lightning impulse withstand voltage 2400kV (peak value); Switching impulse withstand voltage 1800kV (peak value).Specified 1min power-frequency withstand voltage 1100kV (effective value), the security reliability of product is greatly improved.
4, the good stability of electrical property: reach intimate-association state by adhesive linkage between the matsurface of insulating cylinder outer wall and the umbrella cover of organic composite material, guaranteed the stability of the electrical property of product in running.Experiment shows that this product is the energy reliably working in the lifetime of product, can not occur along the problem of bonding plane flashover.
5, the scope of application is wide: the present invention is applicable to the power transmission and transforming equipment of the various AC and DC electric pressures of protection, is particularly suitable for the strong area of the dirty performance of requirement of mechanical strength height, resistant of lightning arrester is being used.Use under the condition of voltage levels, advantage of the present invention is bigger, and experiment shows that electric pressure is high more, and advantage of the present invention is outstanding more.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
Description of reference numerals, 1-umbrella cover, 2-adhesive linkage, 3-insulating cylinder, 4-flange.
Embodiment:
Below in conjunction with accompanying drawing the present invention is explained.
Referring to accompanying drawing, the present invention includes number joint lightning arrester unit.Every joint lightning arrester unit comprises insulating coating and two end flanges 4, described insulating case is two-layer, internal layer is the insulating cylinder 3 of ceramic material, skin is the umbrella cover 1 of silicon rubber composite material, insulating cylinder 3 outer walls are matsurface, are adhesive linkage 2 between the matsurface of insulating cylinder 3 outer walls and the umbrella cover 1 of silicon rubber composite material.Adopt mucilage binding to connect between insulating cylinder 3 and the flange 4, the mucilage binding technology of employing is identical with the mucilage binding technology of full porcelain.
During manufacturing, can process the insulating cylinder 3 of ceramic material earlier, the surface of insulating cylinder 3 is a matsurface, brushing bonding agent on matsurface then, form adhesive linkage 2, umbrella cover 1 with silicon rubber composite material is crimped on its outside at last, the insulating cylinder 3 that makes the internal layer ceramic material and the umbrella cover 1 of the outer silicon rubber composite material formation insulating coating of combining closely, and mucilage binding connects between insulating cylinder 3 two ends and the flange 4; After also can be earlier mucilage binding between insulating cylinder 3 two ends and the flange 4 being connected, the umbrella cover 1 of crimping silicon rubber composite material again.
