Description

Technical Field

[0001] The invention relates to the technical field of transformer substation fire walls, in particular to a wall bushing fireproof partition wall structure for transformer substations. Background Art

[0002] The busbar is used to connect the outdoor transformer and the distribution device room, and the busbar is connected to the distribution device room using a wall bushing. Therefore, as one of the important equipment in the power transmission and transformation project, during the operation of the substation, overheating of the busbar may cause the wall bushing to fail or even cause a fire. At the same time, according to the "Code for Fire Protection Design of Thermal Power Plants and Substations" (GB50229-2019), the wall bushing passing through the distribution device room close to the outdoor substation needs to be sealed with fireproof sealing materials. According to the current research on wall bushings in existing substations, the wall bushing part usually adopts steel plate isolation and sealing technology, which has poor fire protection effect and is difficult to meet the fire resistance limit requirements.

[0003] According to Chinese patent CN216616558U, a wall bushing fireproof partition structure for substations is designed. The design of the wall bushing fireproof partition for substations shortens the distance between the main transformer and the distribution device room, meets the fire protection requirements of other material partition construction processes, and forms an economical and reasonable wall bushing fireproof technology for 35kV and 10kV substation distribution rooms, eliminating fire safety hazards and avoiding serious casualties and economic losses.

[0004] There are some shortcomings in the existing technology. In the existing technology, the connection between the wall sleeve and the fireproof partition is usually fixed by using angle steel and steel plate through bolts. At the same time, the wall sleeve's own stiffener and the inner steel plate are fixed by bolts. However, when the wall sleeve and the fireproof partition need to be disassembled and maintained, disassembly is difficult, which is inconvenient for operators to maintain the wall sleeve and the fireproof partition in time. For this reason, we propose a wall sleeve fireproof partition structure for substations. Summary of the Invention
