Abstract
The invention relates to the high-voltage power transmission and transformation field, particularly to a particle capturing apparatus and power transmission and transformation equipment. The particle capturing apparatus comprises a shielding cover that 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.

Accompanying drawing explanation
Fig. 1 is the structure chart of power transmission and transforming equipment of the present invention;
Fig. 2 is the structure chart of particle capture device in Fig. 1.
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 particle capture device being positioned at cylindrical shell 1, particle capture device comprises the radome 2 that Open Side Down, radome 2 is umbrella hood, the inwall of cylindrical shell 1 is installed with pedestal 3, radome 2 is by bolt 4 detachably fixed pedestal 3, form the cavity of zero potential between radome 2 and cylindrical shell 1, between the edge of radome 2 and the inwall of cylindrical shell 1, form the gap 10 entering described cavity for particulate.The value of the width L in gap 10 according to electric Field Calculation need determine.In the present embodiment, bolt 4 is made up of nonconducting nonmetallic materials, to reduce the impact caused the electric field in cylindrical shell.
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.
In other embodiments, radome can also adopt the cover body of other arbitrary shapes, as long as and form zero potential cavity between cylindrical shell and play shielding action.The mode that fixed structure between radome and cylindrical shell also can not adopt bolt fixing, depression can be set respectively between radome and cylindrical shell with protruding, thus form removable plug-in structure, the non-disconnectable fixed form of directly to be welded with pedestal by radome or bonding together can also be adopted.In addition, also can not adopt pedestal, and radome is directly installed on cylindrical shell by stay bolt or other fixed structures.
