Fire protection and noise reduction device of indoor transformer substation

Abstract

The invention relates to the technical field of electric power engineering, in particular to a fire protection and noise reduction device of an indoor transformer substation. The fire protection and noise reduction device comprises a transformer room which is provided with an opening in the top, and a fire-fighting noise reduction box which covers the top of the transformer room; a transformer isarranged in the transformer room; the interior of the fire-fighting noise reduction box is divided into a plurality of cavities arranged side by side, and the cavities comprise the noise reduction cavity and the fire-fighting cavity; a noise reduction film sheet is arranged in the noise reduction cavity, and a sound radiation inlet hole used for being communicated with the interior of the transformer room is formed in the bottom of the noise reduction cavity; and a transmission mechanism used for driving the fire-fighting noise reduction box to fall off from the top of the transformer room isarranged in the fire-fighting cavity, and a smoke sensing hole used for being communicated with the interior of the transformer chamber is formed in the bottom of the fire-fighting cavity. Compared with the prior art, the device provided by the invention can simultaneously realize fire protection and noise reduction functions.

Description

technical field [0001] The invention relates to the technical field of electric power engineering, in particular to a fire-fighting and noise-reducing device for an indoor substation. Background technique [0002] With the rapid development of urban construction, the number of new substations in cities is increasing. In order to reduce the impact of substation noise on the surrounding environment and coordinate with urban environmental planning, new substations are generally required to be designed with an all-indoor layout plan. Compared with outdoor stations, indoor stations occupy a smaller area and are more economical, but at the same time put forward higher requirements for equipment layout. Due to the particularity of the structure of the indoor substation building and the operating characteristics of related equipment, the substation has strict requirements on fire prevention work, and at the same time, it is necessary to strictly control the impact of noise on the st...

AI Technical Summary

Problems solved by technology

[0003] However, the existing indoor substation is located in a basically airtight indoor space, and fire alarms often use linear temperature-sensing cables, aspirating smoke and infrared radiation detectors. After being put into operation, once a failure occurs, it is difficult to maintain and repair

Sometimes a power outage is required for maintenance, which brings great inconvenience to the reliability of power supply and the electricity consumption of residents
