Abstract
The utility model relates to a large-bore tube bus armour clamp, solving the problem that the tube bus armour in the prior art does not has the self-shielding action independently and does not satisfy the requirements of the hardware fittings of a supervoltage grade high-current power station. The utility model is characterized in that the bottom of slide hardware fittings and telescopic hardware fittings are provided with roller mechanisms; connecting leads on the telescopic hardware fittings are distributed in sector shapes; terminals adopt spherical shielding hardware fittings. The utility model has the advantages that the electric field is uniformly distributed, under the condition of not installing shield rings, the problems of the corona and the radio disturbance of supervoltage electric power hardware fittings are solved, and simultaneously the structures of the hardware fittings are more simple and more reliable.
Description
The utility model belongs to electricity field, particularly a kind of large-diameter pipe bus gold utensil that is used for outdoor power distribution unit.
The terminal of pipe bus gold utensil of the prior art adopts semicircle capping, also have and adopt spherical structure, but in the design of the radius of a ball, do not reach self anticorona requirement, slide construction is all adopted in the bottom of flexible gold utensil and slip gold utensil, vertical tension to post insulator is big, make the post insulator fracture easily, and the connection conductive wire cross-section of flexible gold utensil linearly distributes, can not play the worn-out effect of screen, can not shield at bus self under the situation of worn-out gold utensil, need guarantee that gold utensil does not produce corona under specified electro ultrafiltration by the worn-out ring of screen is installed, and because the worn-out ring of screen has been installed, make the complex structure of gold utensil, weight increases, the stressed increase of post insulator.Because the defective of said structure, pipe bus gold utensil of the prior art does not satisfy the needs of big electric current superhigh voltage distribution equipment.
The purpose of this utility model is to overcome the deficiencies in the prior art part, the needs that adapt to superhigh pressure grade large-current electric station gold utensil, a kind of large-diameter pipe bus gold utensil is provided, guarantee corona free under certain condition simultaneously, and make gold utensil under the effect of horizontal force, can freely stretch, thereby improve shock-resistant ability.
Concrete structure of the present utility model comprises that fixedly gold utensil, slip gold utensil, flexible gold utensil, end-blocking gold utensil, the worn-out gold utensil of spherical end panel, suspention gold utensil and horizontal and vertical T connect gold utensil, the bottom of said slip gold utensil and flexible gold utensil is an idler wheel mechanism, and the connection lead on the said flexible gold utensil is fan-shaped distribution.
Advantage of the present utility model is:
1, because idler wheel mechanism is adopted in the bottom of slip gold utensil and flexible gold utensil, reduced the stress of post insulator effectively, and, do not overlapped the phenomenon of rupture that occurs post insulator again owing to improved the stress of post insulator.
2, because the connection lead on the flexible gold utensil adopts fan-shaped distribution, played and improved heat radiation, reduce temperature rise and electric-field intensity distribution is acted on uniformly, and the corona that utilizes being evenly distributed with of its electric field to solve the chassis gold utensil produces with imitating, under the situation that the worn-out ring of screen need not be installed, the corona of ultrahigh voltage power gold utensil and the problem of radio interference have been solved preferably, together with the idler wheel mechanism of gold utensil bottom, make gold utensil have characteristics such as simple in structure, in light weight, impact resistance, antidetonation and windproof performance simultaneously.
3, because terminal adopts the worn-out gold utensil of spherical screen, not only satisfied the ultrahigh voltage power gold utensil 1.1 * 550
The KV effect is corona free down, and radio interference is less than 2500 microvolts, and is only high 30,000 volts than rated voltage by calculating and testing, and proves that the worn-out gold utensil of this end panel is not only reasonable but also most economical.
The utility model proves by experiment, terms and conditions all satisfies the needs of ultrahigh voltage power facility, be applicable to and send out power transformation engineering, be specially adapted to 500 kilovolts, the gold utensil requirement at large-current electric station, rated voltage is 500 kilovolts, the highest working voltage 550KV, maximum current 6000A, aluminum tube bus scale Φ 250/230mm, pipe bus distance to the ground 7.5m is 1.1 * 550
The 1HZ radio interference does not have visual corona fine night less than 2500 μ V under the effect of KV voltage.
