Abstract
The invention discloses a pollution-resistant porcelain insulator which comprises a porcelain insulator body, and the porcelain insulator body comprises the following chemical compositions in percentage by weight: 40-50% of silica, 30-40% of aluminium oxide, 3-6% of potassium hydroxide, 5-10% of ferric oxide, 7-12% of magnesium oxide, and 5-8% of sodium oxide. Through the way, the pollution-resistant porcelain insulator disclosed by the invention is smooth in surface, pollutions are uneasily accumulated on the insulator, and the pollution-resistant porcelain insulator has stable and reliable mechanical load properties and pollution flashover resistance; the pollution-resistant porcelain insulator is low in cost, light in mass, and convenient to install.
Description
Technical field
The present invention relates to insulating part field, particularly relate to a kind of anti-pollution type porcelain insulator.
Background technology
The effect of insulator is fixing cord, play a part to support and hang wire and make wire and shaft tower insulation, insulator also bears vertical load and the horizontal loading of wire simultaneously, so it should have enough insulation strengths and physical strength, the erosion of chemical miscellaneous affair is had to enough resist abilities simultaneously, can also adapt to the variation of ambient atmosphere condition, as temperature and humidity changes the impact on itself, therefore, insulator must have good insulating property and mechanical property.
At present, porcelain insulator is most popular insulator in power system, the feature of porcelain insulator is that insulating property, mechanical property and electric property are good, but shortcoming is that insulator is made used time insulating property at power-frequency voltage and sharply declined the in the situation that of filthy humidity, the normal local arc that produces, when serious, can produce flashover, the spread voltage of insulator is inhomogeneous, and corona often occurs at the position concentrated at electric field, produce wireless interference, and easily cause porcelain body aging.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of anti-pollution type porcelain insulator, and smooth surface is difficult for contamination, has reliable and stable mechanical load performance and resistant and dodges performance.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of anti-pollution type porcelain insulator is provided, comprise porcelain insulating body, the chemical composition of described porcelain insulating body and weight percent are: silicon-dioxide 40-50%, aluminum oxide 30-40%, potassium oxide 3-6% ferric oxide 5-10%, magnesium oxide 7-12%, sodium oxide 5-8%; Described anti-pollution type porcelain insulator is the streamlined insulator of umbrella.
In a preferred embodiment of the present invention, the chemical composition of described porcelain insulating body 1 and weight percent are: silicon-dioxide 43-46%, aluminum oxide 34-36%, potassium oxide 2-4.5% ferric oxide 7-8%, magnesium oxide 7-9%, sodium oxide 5-7%.
In a preferred embodiment of the present invention, described porcelain insulating body adopts hot pressed sintering mode, and firing time is 8 hours, and firing temperature is 1200 ℃
The invention has the beneficial effects as follows: a kind of anti-pollution type porcelain insulator of the present invention, smooth surface is difficult for contamination, have reliable and stable mechanical load performance and resistant and dodge performance, and cost is low, and quality is light, convenient installation.
