卵石层的不同铺设方式对变压器集油池的排泄能力影响研究

Research on the influence of different laying methods of pebble layer in oil-immersed transformer oil collection pool on drainage capacity

大型油浸式变压器套管炸裂故障起火后,变压器排油以及消防水喷淋抑制电气火灾时,大量油水混合物排入集油池,若卵石层排泄能力存在问题,将进一步扩大火势。通过试验研究卵石层的不同铺设方式对变压器集油池的排泄能力影响,为油浸式变压器集油池排泄能力设计、卵石层铺设方式及电气火灾救火方式提供指导意见。

In the case of a large oil-immersed transformer casing blows up and a fire starts, the transformer drains oil and the fire sprinklers suppress the electrical fire, and a large amount of the oil-water mixture is discharged into the oil catchment, which will further expand the fire if there are problems with the drainage capacity of the pebble layer. This paper investigates the effect of different ways of laying the pebble layer on the drainage capacity of the transformer sumps. Guidance is provided for the design of the drainage capacity of oil-immersed transformer sumps, the way in which the pebble layer is laid and the way in which electrical fires are put out.oil-immersed transformer;pebble layer;oil pool;drainage capacity.
