[ technical field ] A method for producing a semiconductor device

The invention relates to an oil leakage monitoring device 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.

[ summary of the invention ]

The invention aims to provide an oil leakage monitoring device of a transformer substation, so that the shaking degree of the monitoring device can be reduced when the liquid level floats.

In order to solve the technical problem, the preferable structure of the oil leakage monitoring device of the transformer substation comprises a monitor, the monitor is placed in a water seal well and/or an accident oil pool and/or a rainwater well, the monitor comprises a floating part and a sinking part, the floating part is located above the liquid level, the sinking part is located below the liquid level, a bilge keel is arranged on the outer surface of the sinking part, a height adjusting device is arranged on the floating part, a conductivity sensor is arranged on the height adjusting device and comprises a probe, the probe is located at the junction of the liquid level and air, the height adjusting device drives the conductivity sensor to move by adjusting the self-movement, a weight adjusting device is arranged in the sinking part, and the sinking part can float or sink through the weight adjustment of the weight adjusting device.
