Rural power grid distribution transformer

Abstract

The invention discloses a rural power grid distribution transformer. The rural power grid distribution transformer structurally comprises a case, a heat dissipation panel, a bottom plate and an installation rod, the bottom of the case is connected to the upper surface of the bottom plate in a welded mode, the heat dissipation panel is fixedly embedded in the outer surface of the case, and the bottom of the bottom plate is connected with the installation rod through bolts. The transformer has the beneficial effects that swing blocks in through holes in positioning rods temporarily store fallingrainwater, the positioning rods and a cooling fin are driven by the gravity of the rainwater to move downwards, the rainwater can flow downwards conveniently, the situation that the cooling fin rustdue to the fact that the rainwater remains on the cooling fin is avoided, a drainage plate is stressed to move downwards along with a supporting plate in the pressing process of the cooling fin, the drainage plate shakes up and down under the elastic force of the rubber spring, the cooling fin shakes up and down to shake rainwater down to the surface of the drainage plate, meanwhile, an air bag isextruded to blow air into a through pipe, and the air is blown into the air blowing hole to enable a baffle to be opened to blow the rainwater on the drainage plate, so rainwater drainage is accelerated, and rusting of the heat dissipation panel caused by rainwater remaining in the heat dissipation panel is avoided.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a rural power distribution transformer. Background technique [0002] Distribution transformer refers to a kind of electrical equipment used to transform AC voltage and current in the power distribution system to transmit AC power. For the safe installation of distribution transformers, it is usually installed on the pole or in the open. Transformers enable every household to use stable voltage and current. [0003] At present, there is an existing distribution transformer for rural power grids. In order to avoid harm to people’s lives, the transformer is usually installed in an outdoor location in a remote corner with relatively little traffic. The heat dissipation panel on the surface of the transformer is convenient for heat dissipation of the transformer. In the seasons of alternating sunny and rainy seasons, raindrops remain on the heat dissipation panel, causing the rainwater t...

[0003] At present, there is an existing distribution transformer for rural power grids. In order to avoid harm to people’s lives, the transformer is usually installed in an outdoor location in a remote corner with relatively little traffic. The heat dissipation panel on the surface of the transformer is convenient for heat dissipation of the transformer. In the seasons of alternating sunny and rainy seasons, raindrops will remain on the heat dissipation panel, causing the rainwater to corrode the heat dissipation panel under the sun's exposure, resulting in rust and damage to the heat dissipation panel, which will affect the heat dissipation of the transformer.
