Abstract

Duct for coming bus penetrating wall is made up of insulator, rectangular copper bar conductor, caulking gum packing ring, aluminium end cap, aluminium flange, felt paper packing ring, split pin, bolt, nut, spring washer.Two rubber gaskets are embedded in respectively in the two ends of insulator lumen pore, two aluminium lids are embedded at respectively in the caulking gum packing ring, article two, the copper bar conductor passes from two holes of aluminium end cap and insulator lumen pore respectively, with two rectangular copper bar conductor and aluminium end cap caulking gum packing ring, insulator is fixed together with split pin.Make liner with felt paper between two ZL that opens-102 type aluminium ring flanges and the insulator, fasten as one with M10 bolt, nut and spring washer.

Description

Duct for coming bus penetrating wall

The invention belongs to power station or electric substation power distribution equipment field.

Prior art for unification of the motherland designs the model of producing is: the CMD-10 series of products, form by porcelain tube, flange, copper bar etc.Its leakage distance is 150 millimeters, 1000 kilograms of machinery bending resistance, tensile strength, ambient temperature ± 40 ℃, use height above sea level to be no more than 1000 meters, place to use relative humidity is no more than percent 85, can not use in filthy area and the copper bar contact area is too little and to produce temperature rise too fast, too high, causes the joint scaling loss, thereby reduced the useful life of product, increased maintenance load and economic loss for power station or change, distribution.

The objective of the invention is to change at what the shortcoming and defect of prior art, improve the voltage gradation of bus casing, a kind of mechanical performance is provided, electric property, cold and hot performance are more good, applicability power station and power transformation more widely, power distribution unit.

Solution of the present invention is that two caulking gum packing rings are set respectively in the two ends of what insulator lumen pore, again two 2L-102 aluminium end caps are embedded at respectively in the fluid sealant packing ring, the two ends exposed parts is silver-plated or ward off two rectangular copper bar conductor that tin handles and pass from the lumen pore of two holes of aluminium end cap and insulator respectively, with split pin two rectangular copper bar conductor and aluminium end cap, caulking gum packing ring, insulator is fixed together.Make liner with felt paper in the middle of two 2L-102 aluminium ring flanges of opening and the insulator, use the N10 bolt, nut and spring washer fasten as one, the major part insulator is by clay first percent 55 by raw material, quartzy percent 20, feldspar percent 25 or glaze, clay percent 20, quartzy percent 28, feldspar percent 30, talcum percent 7, porcelain powder percent 10, the ratio of lime stone percent 5 is prepared burden, and in material: abrasive body: 1: 1: 0.8 ratio of whats such as water is carried out ball milling, ball milling gained mud carried out secondary sieves or multistage sieving, to remove de-iron and other impurity, guarantee moil fineness, further pure pug.Mud cake behind the press dewatering is put into the mud storehouse carry out oldly, the old time is no less than 5 hours, and temperature is not less than 10 ℃, to improve the plasticity and the mouldability of pug.Adopt the moulding of plastic type method again after vacuum pugging is minimized gas in the pug, the base substrate water content after the moulding is at percent 18-20, and plasticity is big, and intensity is low, need carry out dried.Base substrate after the dried is coated with last layer white or brown enamel people klining one-tenth on base substrate after the base inspection.In sintering process, the material generation series of physical of base substrate changes and chemical change, and particle combines securely.Obtain having the insulator of certain intensity and desired properties after burning till.Insulator is assembled together with other annex through after the quality inspection, promptly becomes a kind of novel outdoor bus insulator through walls.As stated above, by different each accessory sizes of instructions for use, can produce the series of products of this invention.

Compared with the prior art the present invention has the following advantages:

Rectangular copper bar conductor adopts two copper bars, has strengthened the contact area of copper bar conductor, prevents that temperature rise is too high, causes the phenomenon of joint scaling loss.Add that two ends expose partly silver-plated or ward off tin and handle, change the existing easy oxidative exfoliation shortcoming of plain edition, on the insulator structure, take all to press measure, strengthen, thickeied the umbrella and the porcelain wall at nearly flange position, and in the glazing of insulator inner chamber, changed Electric Field Distribution, improved the initial corona and the gliding spark discharge voltage of insulator, therefore prevented that the insulator inner chamber from discharging.Height above sea level is brought up to below 3000 meters, and leakage distance is increased to 220 millimeters, improves existing creepage distance deficiency, mechanical bending resistance, and tensile strength is increased to 2000 kilograms, changes anti-fouling type into by plain edition.But equal operate as normal under high temperature, high and cold, coastal, humidity and filthy environment no matter.

Accompanying drawing 1,2 is an assembling schematic diagram of the present invention

Most preferred embodiment of the present invention is with the ratio batching of raw material in clay percent 55, quartzy percent 20, feldspar percent 25 or glaze clay percent 20, quartzy 28.7 percent, feldspar percent 30, talcum percent 7, porcelain powder percent 10, lime stone percent 5, through sand in ball milling, the deironing of sieving, press filt, old, vacuum pugging, moulding, drying, base inspection, the glazing, burn till, after the working procedure processing such as porcelain inspection, make the major part insulator.Getting a qualified insulator (3) sets two caulking gum packing rings (6) respectively in the two ends of what insulator (3) lumen pore, again two ZL-102 type Al end caps (2) are put respectively in the what caulking gum packing ring (6), two ends are exposed partly silver-plated or are warded off two rectangular copper bar conductor (1) that tin handles and pass from the lumen pore of two holes of aluminium end cap (2) and insulator (3) respectively, with split pin (7) two rectangular copper bar conductor (1) and aluminium end cap (2), caulking gum packing ring (6), insulator (3) are fixed together.Be separated by with felt paper liner (4) between two ZL-102 aluminium ring flanges of opening (5) and the insulator (3), fasten as one with M10 bolt (8), nut (9) spring washer (10).
