Background technology
Insulator is a kind of special insulation control, can play an important role in overhead transmission line.In one's early years, insulator is used for electric pole, and slowly develop and hung the insulator of a lot of plate-like in one end of high type high-tension bus-bar connection tower, it is made up of glass or pottery usually in order to increase creepage distance.Insulator should not to change the various dynamo-electric stress that causes and losing efficacy due to environment and electric loading condition, otherwise insulator would not produce great effect, will damage use and the service life of whole piece circuit.
The most simplicity of design of insulator common at present, and electric pole often needs to support a more than power transmission line, traditional insulator is merely able to erect a power transmission line, thus causes great waste.
Summary of the invention
The technical problem that the utility model mainly solves is to provide a kind of disc insulator, erecting two power transmission lines simultaneously, solving the defect that existing insulator stringing is less by designing disc insulator.
For solving the problems of the technologies described above, the utility model relates to the electric apparatus field of conveying, relate to a kind of disc insulator in particular, this disc insulator comprises a discoidal insulator, the upper and lower surface of insulator is protruding cone cylinder body shape, the side of insulator has two cylindrical through wires holes be parallel to each other, and through wires hole is equal to the distance at insulator center, the inside of two through wires holes is equipped with an insulated tube manufactured by rubber, the heart portion of insulated tube has a columniform centre bore, center-hole diameter equals the diameter of power transmission line, the center, both ends open place of two through wires holes is equipped with the wrapping post of a column, wrapping post and insulator are monolithic construction, wrapping post is provided with two circle helical grooves.
Insulator bottom is provided with a cylindrical erection column, is provided with a bolt column below erection column, and the diameter of bolt column is less than the diameter of erection column, and bolt column is furnished with a nut.
As the further optimization of the technical program, described in a kind of disc insulator of the utility model, insulator and erection column are by insulating ceramic materials manufacture.
As the further optimization of the technical program, described in a kind of disc insulator of the utility model, the length of insulated tube is less than the length 6-8 ㎜ of through wires hole, and insulated tube and through wires hole interference fit.
As the further optimization of the technical program, the cross section of helical groove described in a kind of disc insulator of the utility model is semicircle, and diameter of section is greater than the diameter of power transmission line.
As the further optimization of the technical program, insulator described in a kind of disc insulator of the utility model and erection column and bolt column all coaxial.
The beneficial effect of a kind of disc insulator of the utility model is: the upper and lower surface of this disc insulator is protruding cone cylinder body shape, rainwater dirt all can smooth and easyly flow away, the side of insulator has two cylindrical through wires holes be parallel to each other, the inside of two through wires holes is equipped with an insulated tube manufactured by rubber, the center, both ends open place of two through wires holes is equipped with the wrapping post of a column, wrapping post is provided with two circle helical grooves, this disc insulator can fix two transmission pressures simultaneously, substantially increase operating efficiency, and by insulator and the isolation of insulated tube bilayer, insulation effect is good, during installation by wire round the helical groove of wrapping post around Liang Quan, more transmission pressure can be fixed, can effectively prevent wind wire to shake accidents such as causing short circuit, be suitable for being applied in various transmission of electricity occasion.
