[ technical field ] A method for producing a semiconductor device

The invention relates to a flow-resistant oil leakage detection rod and an accident oil pool structure of a transformer substation, and belongs to the field of transformer substation safety equipment.

[ background of the invention ]

After the transformer emergence accident leaked oil in the transformer substation, the oil leak flowed out and can lead to the fact oil pollution, for preventing that fluid from leaking outward, often adopted the mode that sets up the accident oil pool, through will leaking oil separation storage for the oil leak can not leak, can take place to catch fire when fluid leaked, often through with oil guide-in water seal well, the water in the utilization water seal well made it go out.

In order to prevent oil leakage from flowing out and polluting, a monitoring device is usually adopted in an accident oil pool structure for real-time monitoring, and a commonly used monitoring device is provided with a buoy monitor.
