Rainproof type transformer

Abstract

The invention provides a rainproof type transformer. The rainproof type transformer comprises a transformer box, a transformer body, a top cover, a humidity sensor and a telescopic plate; the top cover is arranged above the transformer box at a preset angle in an inclined manner; the humidity sensor used for sensing the external air humidity is arranged on the top cover; the telescopic plate, which is mounted in parallel to the top cover and is retractable, is arranged on the lower surface of the top cover; baffles for baffling rainwater are arranged above each radiating hole; when the humidity sensor detects that the external air humidity is greater than a preset value, the telescopic plate stretches to a preset position, and the baffles are inclined to a preset angle. According to the rainproof type transformer, when the humidity sensor detects that the external air humidity is greater than the preset value, the telescopic plate stretches to better perform a rainproof function so as to prevent the transformer box from being affected with damp; and meanwhile, the baffles with adjustable angles are arranged above the radiating holes, so that a relatively good radiation performance is ensured, and rainwater is prevented from entering the interior of the transformer box from the radiating holes as well.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular, the invention relates to a rainproof transformer. Background technique [0002] Outdoor transformers have high requirements for rainproof performance. The existing transformers are usually placed in the transformer box. However, if the transformer needs to be repaired in rainy days, the box needs to be opened. After the box is opened, it cannot effectively block the rain. If the maintenance personnel do not use an umbrella, rainwater will enter the transformer from above or through the cooling holes, causing equipment damage and accidents, and it is very inconvenient for the maintenance personnel to open an umbrella. Therefore, those skilled in the art urgently need to provide a rainproof transformer with a reasonable structure, which can prevent the transformer in the transformer box from getting wet due to rainwater, and at the same time ensure better heat dissipation perfor...
