Embodiment 1

[0026] refer to Figure 1-4 , an oil-immersed transformer bushing protective cover, including a base 1, a transformer 2 is welded on the top of the base 1, an incoming line bushing 4 and an outgoing line bushing 5 are respectively provided on the top of the transformer 2, and the top of the transformer 2 is welded with The protective cover 3 has rectangular openings on both sides of the protective cover 3. The protective cover 3 is welded with a heat dissipation box 20 at the rectangular opening. One side of the net plate 15 is provided with a dust-proof net 6, the inner wall of the bottom end of the protective cover 3 is welded with a bracket 8, the top of the bracket 8 is welded with a connecting pipe 9, and the two ends of the connecting pipe 9 are respectively connected with a first rotating shaft through a rotating shaft. Rod 10 and second rotating rod 17, the first fan blade 11 is welded on one end of the first rotating rod 10, the second fan blade 18 is welded on one en...

Embodiment 2

[0035] refer to Figure 5 , an oil-immersed transformer bushing protective cover. Compared with Embodiment 1, in order to make the dust-proof net shake dust better, the top of the transformer 2 is welded with a connecting plate 29, and the top of the connecting plate 29 is provided with Several springs 30 are welded with a protective cover 3 at the top of the spring 30, and the protective cover 3 is slidably connected with the incoming line sleeve 4 and the outgoing line sleeve 5. When the ground vibrates, the spring 30 at the top of the connecting plate 29 amplifies the vibration, so that The vibration of the dust-proof net 6 improves the vibration amplitude of the dust-proof net 6 and prevents dust from accumulating on the dust-proof net 6, which affects heat dissipation.

[0036] During use, when the device encounters the wind that blows, the first fan blade 11 rotates to drive the soft brush, and the soft brush brushes the dustproof net 6, and the dustproof net 6 is cleane...

Abstract

The invention belongs to the technical field of electrical equipment, in particular to an oil-immersed transformer bushing protective cover. The invention aims to solve the problem that an long-used existing oil-immersed transformer with a protective cover is poor in heat dissipation performance of a dust screen due to dust extrusion. The technical scheme is proposed in that the cover comprises abase, a transformer is fixedly connected to the top of the base; the top end of the transformer is provided with a wire inlet sleeve and a wire outlet sleeve; the top of the transformer is fixedly connected with a protective cover; rectangular openings are formed in the two sides of the protective cover, a heat dissipation box is fixedly connected to the rectangular openings of the protective cover, a metal net plate is fixedly connected to the outer portion of one side of the heat dissipation box, a dustproof net is arranged on one side of the metal net plate of the heat dissipation box, a support is fixedly connected to the inner wall of the bottom end of the protective cover, and a connecting pipe is fixedly connected to the top end. Fan blades and banister brushes are arranged to rotate to clean the dustproof net, so that dust accumulation is prevented, airflow movement in the protective cover is accelerated, and the heat dissipation capability is improved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment design, in particular to an oil-immersed transformer bushing protective cover. Background technique [0002] In our daily life, we often see many high-voltage oil-immersed transformers standing in the streets and alleys. Because there are no protective measures for the inlet and outlet bushings of these transformers, they may Electric creepage will occur, and arcing will occur, which will affect the life of the equipment and may touch people's lives and property. However, some existing oil-immersed transformers with protective covers can well isolate the dust from the outside, but The heat dissipation performance is very poor, which affects the normal operation of the transformer. [0003] After searching, the Chinese patent application number is CN201420373071.1, which discloses an oil-immersed transformer bushing antifouling cover, which includes a sealed antifouling cover and a co...
