Abstract

The invention discloses a transformer substation transformer noise radiation control platform. The transformer substation noise radiation control platform comprises a transformer arranged on a substrate, a steel frame platform arranged on the periphery of the transformer, and a shielding device arranged on the steel frame platform in a lifting manner, wherein a circular lifting groove is formed in the steel frame platform around the transformer, a bottom frame matched with the shape of the lifting groove is arranged below the lifting groove, an electromagnetic shielding mechanism and a noise shielding mechanism are arranged on the bottom frame, and a lifting mechanism is arranged on the bottom frame. According to the transformer substation transformer noise radiation control platform, noise and radiation shielding absorption for the transformer is realized by lifting the encircling type shielding device, the control platform is flexible and convenient to use, circuits above the transformer and the operation for workers on the steel frame platform cannot be influenced, the structure is simple, complicated and expensive equipment is not needed, the control platform is easy to popularize, and the affected environmental influence of transformer substation workers and nearby residents can be reduced effectively.

Description

technical field [0001] The invention relates to the technical field of electromagnetic radiation and noise suppression, in particular to a substation transformer noise radiation control platform. Background technique [0002] At present, there are common problems in substations such as high electromagnetic radiation, weak fire and impact resistance, and high noise. Among them, the electromagnetic radiation pollution produced by the high alternating power frequency electromagnetic field can interfere with the bioelectricity of the human body, and even seriously affect the normal function of the human brain and heart activity. The magnetostrictive vibration of the silicon steel sheet of the transformer core and the electromagnetic and mechanical noise generated by the reactor vibration will affect the working performance of the equipment and interfere with the normal life of the surrounding residents. Especially with the acceleration of urbanization, the demand for electricit...
