Abstract
The invention relates to the high-voltage power transmission and transformation field, particularly to a flat plate type particle capturing apparatus and power transmission and transformation equipment. The flat plate type particle capturing apparatus comprises a shielding cover containing a flat plate part. The shielding cover is fixed at the inner wall of a cylinder based on a fixation structure; a zero-potential cavity is formed between the shielding cover and the cylinder; and a gap for particle entrance into the cavity is formed between the edge of the shielding cover and the inner wall of the cylinder. A particle can enter the cavity inside the shielding cover through the gap; an electric-field acting force of the particle is eliminated under the shielding effect of the shielding cover. Besides, the shielding cover can be used for preventing particle floating inside the cavity and thus the particle can not escape to a high-electric-field area, thereby avoiding an insulation breakdown caused by electric field distortion due to the particle and reducing the influence on the insulation performance of the power transmission and transformation equipment by the particle. The shielding cover is arranged inside the cylinder to capture particles. The shielding cover uses a flat plate structure; and the structure is simple and processing is convenient.

The Chinese patent document that Authorization Notice No. is CN101529679B, authorized announcement date is on October 22nd, 2014 discloses a kind of power transmission and transforming equipment, comprise cylindrical shell and the particle capture device being positioned at cylindrical shell lowest part, particle capture device is electrically connected with cylindrical shell by welding, particle capture device comprises corrugated plating and is arranged on the wavy end of corrugated plating and the metal round rod be electrically connected with corrugated plating, and the surface of corrugated plating and metal round rod is implemented insulating wrapped.In use, the recess of corrugated plating becomes low electric field portion, and particulate is owing to being subject to electrostatic force and gravity moves down and enters the recess of corrugated plating, and the particle capture device after insulating wrapped can suppress charged to metal particle, thus suppresses particulate to float.Although this particle capture device can reduce the impact of particulate on power transmission and transforming equipment insulation property to a certain extent, be subject to the restriction of its operation principle, the complicated structure of device.
Summary of the invention
The object of the present invention is to provide the simple flat particle capture device of a kind of structure and power transmission and transforming equipment.
For achieving the above object, the technical scheme of power transmission and transforming equipment of the present invention is:
A kind of power transmission and transforming equipment, comprise cylindrical shell and the flat particle capture device being positioned at cylindrical shell, flat particle capture device comprises radome, radome comprises flat part, radome is fixed on the inwall of cylindrical shell by fixed structure, form the cavity of zero potential between radome and cylindrical shell, between the edge of radome and cylinder inboard wall, form the gap entering described cavity for particulate.
Described radome also comprises the curled portion curling to cover being positioned at radome edge.
Described fixed structure comprises the pedestal be fixed on cylindrical shell.
Described fixed structure comprises the counterbore be arranged on radome and the bolt being arranged on counterbore base, and the head of bolt is arranged in counterbore.
The technical scheme of the flat particle capture device of the present invention is:
A kind of flat particle capture device, comprise radome, radome comprises flat part, radome is provided with the fixed structure for being fixed on by radome on the cylinder inboard wall of power transmission and transforming equipment, when on the cylinder inboard wall being fixed on power transmission and transforming equipment by described fixed structure, form the cavity of zero potential between radome and the cylindrical shell of power transmission and transforming equipment, between the edge of radome and cylinder inboard wall, form the gap entering described cavity for particulate.

The invention has the beneficial effects as follows: particulate enters in the cavity in radome by gap, particulate is subject to the shielding action of radome, lose the active force of electric field, on the other hand radome can float by the particulate in block cavity, make particulate cannot escape into high electric field region, avoid particulate and cause electric field distortion thus the insulation breakdown caused, reduce the impact of particulate on power transmission and transforming equipment insulation property.In cylindrical shell, set up radome realize catching particulate, radome adopts slab construction, and structure is simple, is convenient to processing.The curled portion curling in cover that radome edge is arranged can strengthen shielding action.Make the head of bolt in fixed structure be arranged in counterbore, bolt can be avoided to protrude radome and affect neighbouring electric field, thus reduce the impact of particle capture device on power transmission and transforming equipment insulation property.
Accompanying drawing explanation
Fig. 1 is the structure chart of power transmission and transforming equipment of the present invention;
Fig. 2 is that Fig. 1 middle plateform declines the structure chart of an acquisition equipment.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are described further.
The specific embodiment of power transmission and transforming equipment of the present invention, as shown in Figure 1 to Figure 2, comprise the cylindrical shell 1 that axis extends along the longitudinal direction and the flat particle capture device being positioned at cylindrical shell 1, flat particle capture device comprises the radome 2 that Open Side Down, radome 2 comprises flat part 21 and is positioned at the curled portion 22 curling to cover of covers edge, flat part 21 offers counterbore 23, the inwall of cylindrical shell 1 is installed with pedestal 3, radome 2 is by being positioned on bolt 4 fixed pedestal 3 bottom counterbore 23, the head of bolt 4 is arranged in counterbore 23, the cavity of zero potential is formed between radome 2 and cylindrical shell 1, the gap 10 entering described cavity for particulate is formed between the curled portion 22 of radome 2 and the inwall of cylindrical shell 1, wherein the width L in gap 10 value according to electric Field Calculation need determine.
In the process of power transmission and transforming equipment on-line operation, the particulate produced in cylindrical shell falls into the cavity in radome 2 by gap 10, particulate is subject to the shielding action of radome 2 and loses the active force of electric field, on the other hand radome 2 can float by the particulate in block cavity, make particulate cannot escape into high electric field region, avoid particulate and cause electric field distortion and the insulation breakdown caused, reduce the impact of particulate on power transmission and transforming equipment insulation property.The head of bolt is arranged in the counterbore of radome, bolt can be avoided to protrude radome and affect neighbouring electric field, thus reduce flat particle capture device to the impact of power transmission and transforming equipment insulation property.
