This invention discloses a safety assessment and practical design method for transformer emergency oil drainage, belonging to the field of power safety. Based on the dynamic analysis of emergency oil drainage in oil-immersed transformers, and considering the flow balance conditions of the transformer tank and emergency oil pit, this invention proposes a novel graphical method.

It analyzes the flow balance time when the leakage and drainage flows are equal, and directly calculates the minimum required volume of the emergency oil pit using the area method of the flow diagram. Based on the ratio of the actual volume to the necessary volume of the emergency oil pit, the safety factor for emergency oil drainage is determined, thereby evaluating the drainage capacity of the emergency oil drainage system and the improvement design of the emergency oil pit. This invention avoids the tedious process of solving complex differential equations simultaneously in traditional methods, significantly reducing computational complexity and facilitating rapid mastery and application by engineering designers.

This invention provides a three-dimensional flow field effect condensate trap, comprising: a housing with a storage chamber inside; a nozzle disc dividing the storage chamber into an upper separation chamber and a lower drainage chamber; a Venturi nozzle, the straight end of which connects to the separation chamber, and the tapered end of which connects to the drainage chamber; and an auxiliary drainage component configured to increase the drainage flow rate when the water level in the separation chamber exceeds a set threshold. The beneficial effects of this invention are: steam mixed with condensate enters the separation chamber from the inlet pipe, and the condensate enters the drainage chamber through the Venturi nozzle.

This invention discloses a method for calculating water volume in hilly irrigation areas, relating to the field of irrigation technology. It addresses the problems of large calculation errors and high implementation costs caused by complex terrain and dispersed water sources in hilly irrigation areas. The method first collects basic parameters such as terrain, water sources, meteorology, crops, and monitoring data.

Substituting water source parameters, the total input water volume is calculated. Combined with monitoring data from the beginning and end of ditches, water loss is calculated to obtain the net input water volume. The total return water volume and reuse volume are quantified based on field drainage flow, and then superimposed on the net input water volume to obtain the effective irrigation water volume. Finally, the total irrigation water volume, water source contribution ratio, and return water reuse rate are integrated and output.
