Description
Technical field
The present invention relates to transmission line composite insulator and detection method, particularly the detection method of the close value of the equivalent attached salt of a kind of composite insulator.
Background technology
Insulator refers to insulation between live wire and ground connection shaft tower and the fixing insulating component of machinery.Insulator conventional in overhead transmission line comprises: porcelain insulator, glass insulator, composite rod insulator (being also called composite insulator or composite insulator).
Composite insulator mainly comprises glass-epoxy leading-drawing rod (hereinafter referred to as plug), silicon rubber umbrella skirt and gold utensil three part, gold utensil is the metallic conductor being positioned at composite insulator upper/lower terminal, because composite insulator is the minimum stock insulation system of interelectrode capacity amount, its axial voltage's distribiuting is extremely uneven, especially there is the highest position of field intensity in conductor wire end.Along with the raising of voltage of system grade, the scantlings of the structure of composite insulator increases thereupon, and its axial voltage's distribiuting will be more and more uneven, and the as easy as rolling off a log conductor wire end that causes produces corona.Corona, by interfere with communications circuit, causes energy waste, also can produce nitrogen oxide and ozone, and corroding metal annex and pollution insulator surface, galvanic corrosion silicon rubber umbrella skirt sheath, reduces the insulating property of insulator, destroys composite insulator performance.So it is unallowed for producing corona under operating voltage.Along with improving constantly of China's transmission voltage grade, composite rod insulator obtains a large amount of use as electric transmission line isolator of new generation at China's electrical network, especially in heavy pollution area.The main product of composite rod insulator is with silicon rubber umbrella skirt sheath for external insulation, although manufacture and operation technique relatively ripe, but still continuous renewal and develop in.This is because composite insulator is possessing a large amount of advantage while, also there are some problems: one, the silicon rubber umbrella skirt sheath quality of current use is tenderer, run because insulator is in field for a long time, be subject to the impact of severe weather and environment, the silicon rubber umbrella skirt sheath of its outer surface, very easily damages and breakseal, causes decreasing insulating; Its two, the long rod-like structure of composite insulator makes yield rate lower, and packaging, transport, installation and operation is difficult in maintenance, and Potential distribution is uneven, damage if occur just must whole change maintenance cost increased.The problems referred to above are also not remarkable on general high voltage transmitting line, but for super, UHV transmission line, because the requirement of system insulation level is high, the structure height of composite insulator is general longer, and these problems must be resolved.Insulator is the critical elements of transmitting line and electric installation, and its development directly has influence on the development of transmitting line and electric installation, and will improve reliability and the work-ing life of composite insulator, just need conduct a research to its full skirt external insulator and full skirt shape.
Line insulator because of long-term exposure in atmosphere, easily at its surface deposition dunghill, containing electrolysed substance in dunghill, under the humid conditions such as mist, dew, drizzling rain, the electrical strength of insulator is reduced greatly, may make power system external insulation, under superpotential effect, flashover occur, cause power outage, the normal operation of power system is worked the mischief.
Summary of the invention
The invention provides a kind of quality good toughness, good insulation preformance, the composite insulator material of long service life and the detection method of the close value of equivalent attached salt, this insulator has excellent hydrophobic nature, migration of hydrophobicity, high mechanical strength, good wear resistance and external force resistance destructiveness, can meet insulator processing and operating requirement.
