A pressure relief, fireproof, detachable sound insulation door structure for the main transformer room of an indoor substation

Abstract

The invention provides a pressure relief, fireproof and detachable sound insulation door structure for the main transformer room of an indoor substation, comprising: an installation frame and a sound insulation board, the installation frame includes a steel column, a connecting beam, and a transverse installation frame; the steel The column and the concrete frame of the substation main transformer room opening are fixed by bolts, and the transformer can be dismantled when the transformer needs overhaul; the connecting beam and the steel column are fixed by bolts and can be disassembled; the horizontal installation frame and the steel column are fixed by bolts , can be disassembled; the sound insulation board is installed on the transverse installation bone. When the transformer in the main transformer room explodes first, the sound insulation board on the sound insulation door of the main transformer can quickly dissipate the explosive force and reduce the internal and external damage caused by the explosive force. During the transformer explosion process, along with the fire, when the internal temperature of the sound insulation board reaches 200 ℃ ~ 250 ℃, as the ambient temperature continues to rise, the sound insulation board loses its rigidity, breaks off under the action of its own weight and falls into pieces Down.

Description

technical field [0001] The invention relates to the fields of noise reduction and fire protection in substations, in particular to a pressure relief, fire prevention and detachable sound insulation door structure for a main transformer room of an indoor substation. Background technique [0002] With the increase of urban scale brought about by the development of urbanization in recent years, accompanied by the transformation and expansion of urban infrastructure projects, the increase of residents' electricity demand and the increase of power load density, the substation must go deep into the urban load center. In order to maximize the control of land use, substations in cities generally adopt comprehensive buildings. According to their location and load conditions, power distribution equipment buildings are generally divided into full-indoor substations and semi-indoor substations. [0003] At present, the technology of indoor substations in terms of door, window and wall s...

AI Technical Summary

Problems solved by technology

Once the transformer in the main transformer room of the substation explodes or fires, the sound insulation doors in the prior art documents 1-4 and the double metal doors in the current engineering practice will not effectively release the pressure, and the maintenance of the personnel through the main transformer sound insulation door is small. The door enters the main transformer room to open the soundproof door for fire extinguishing. The safety risk is extremely high, which is not conducive to timely fire extinguishing and fire control on site.
