Abstract
High-strength thermosetting resin mixed with material of high dielectric constant is passed through thermocompression to produce insulator of different capacitance. The said insulator has excellent electrical and mechanical properties and it can resist electrostatic contaminant accumulation and climatic ageing. When constituted into insulator string, insulators of different capacitance are configurated properly so as to improve the voltage distribution in insulator string and raise the whole insulation level.
Description
The present invention relates to the ultra-high-tension power transmission line cap and pin insulator.
At present, ultra-high-tension power transmission line is mainly porcelain insulator with cap and pin insulator.The easily laying dust dirt of glaze surface of its porcelain insulating full skirt causes pollution flashover accident.And along with the raising of transmission line electric pressure, the increase of insulator string insulator sheet number, the spread voltage of insulator string is inhomogeneous more, and the effective rate of utilization of insulator is reduced, and influences the safe operation of electric power system.And porcelain insulator spare at high temperature roasting forms, and rate of finished products is lower.When producing disc insulator, also exist the second pouring cement industry, the production cycle is long, the cost height.
Purpose of the present invention is at the problems referred to above, and a kind of electric, satisfactory mechanical property is provided, and is antifouling, ageing-resistant, production technology is simple, and cost is low, has different capacitances, can improve the Discal suspended large capacity synthetic insulator of insulator string spread voltage.
The present invention realizes as follows, the insulating part of insulator is selected the good high-strength hot solid synthetic resin of electric property for use, as 100 parts of epoxy resin or vinylite, alkyd resins etc., add high dielectric constant material barium titanate 0-70 part and titanium dioxide 0-30 part of increasing the insulator capacitance, making its dielectric constant is that 3-50 mediates evenly.The chapeau de fer and the steel pin of insulator are placed insulating part mould relevant position, and above-mentioned raw materials injects mould, and is once hot-forming.Cover one deck organosilicon or organic fluorine material protective layer the insulated umbrella skirt section of insulating part part, a male seal platform is arranged on the steel pin.
Advantage of the present invention is to adopt the polyester synthetic material to replace ceramic material, makes insulator have excellent electrical insulation capability and mechanical performance.On the insulation full skirt, apply organosilicon or organic fluorine material protective layer, further improved antistatic contamination, weather-resistant and the hydrophobicity performance of insulator.In thermoset synthetic resin, add high dielectric constant material, increase the capacitance of insulator, according to the position of insulator in insulator string, the reasonable configuration insulator of different capacitance, improve the spread voltage of insulator string, improve the integral insulation level, guarantee the line security reliability service.The present invention adopts heat pressure forming process one time, and production process is simple and convenient, has reduced production equipment significantly, and cost is significantly reduced.Male seal platform on the electric insulator steel foot plays sealed mold during production, can improve the Electric Field Distribution at this place during use, plays the sliding effect of dodging that suppresses.Chapeau de fer used in the present invention and steel pin can with the chapeau de fer and the steel pin compatibility of porcelain insulator, thereby made things convenient for of the present invention promoting the use of and the replacing of insulator.
Accompanying drawing 1 structural representation of the present invention
Among the figure: 1-insulation full skirt 2-protective layer 3-steel pin
4-chapeau de fer 5-male seal platform 6-insulating part
The present invention implements as follows, and with organosilicon material such as silicones, silicon rubber or organic fluorine material such as fluororesin, fluorubber etc. are as the protective layer of insulation full skirt, and brushing earlier is in the inwall insulation full skirt position of mould.The steel pin that chapeau de fer that malleable cast iron is made and No. 45 steel that a male seal platform is arranged are made is placed in relevant position in the mould, the prescription of insulating part is: 100 parts in thermoset synthetic resin such as epoxy resin or vinyl resin or mylar, high dielectric constant material barium titanate 0-70 part, titanium dioxide 0-30 part, add filler such as silicon dioxide 30-300 part, reinforcing material such as polyester fiber or glass fibre 30-70 part, inject mould after kneading evenly, to mould electric heating or oil heating, heating-up temperature is no more than 200 ℃, applying the mechanical pressure of 150-200kg/cm with hydraulic press or other machinery, make its moulding, promptly is finished product after the demoulding.
The present invention can be by changing the ratio of high dielectric constant material in the insulation full skirt prescription, making its dielectric constant is 3-50, change the capacitance of insulator, when forming insulator string, the insulator that capacitance is big places the two ends of insulator string, the insulator that capacitance is little places the middle part of insulator string, makes the insulator string spread voltage even, guarantees the safe operation of transmission line.
