Transformer, protection device and fire control assisting module

Abstract

The invention relates to a transformer, a protection device and a fire control assisting module. The transformer comprises a transformer main body and a protection structure; at least one side wall of a protection cavity is enclosed by a protection device; the protection device comprises a plurality of fire control assisting modules; mounting frames of the plurality of fire control assisting modules can be mutually spliced with each other; covering parts of all the fire control assisting modules are located on the same plane in a closed state; each fire control assisting module comprises a covering part, a mounting frame and a switch part; a communicating hole is formed in each mounting frame; an outer opening and an inner opening are formed in the two sides, penetrating through each mounting frame, of each communicating hole respectively; each covering part is connected to each mounting frame, is covered on each outer opening in a turning mode and is used for covering the outer opening; each switch part is arranged at each outer opening; and the switch parts can be fused in a high-temperature environment so as to release the limit of the covering parts. The protection device can be repeatedly used, so that the usage cost of the protection device is reduced.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a transformer, a protective device and a fire-fighting auxiliary module. Background technique [0002] At present, most of the protective shells of converter transformers are installed in a closed manner. After the converter transformer catches fire, firefighters must first break the closed shell of the converter transformer to carry out fire extinguishing operations. This will further intensify the fire, making it difficult to control and posing a huge safety risk. At the same time, due to the emergency of the fire, firefighters will use violent means to break the closed casing, which will inevitably be severely damaged and cannot be reused after the fire, resulting in an increase in protection costs. Contents of the invention [0003] Based on this, it is necessary to address the above-mentioned problems and provide a reusable transformer, a protective devic...
