Description

Technical Field

[0001] This utility model relates to the field of transformer cooling technology, specifically a rapid cooling spray device for transformers. Background Technology

[0002] When the ambient temperature is high or the load is heavy, the heat generated by the transformer can easily lead to high oil temperature if the heat is dissipated by the heat sink alone, resulting in insufficient output capacity of the transformer. In order to reduce the transformer oil temperature, many transformers now use spray equipment to assist in cooling the transformer.

[0003] For example, announcement number CN211099645U, entitled "A Transformer Cooling Spray Device for Easy Assembly," includes a second transmission pipe and a first transmission pipe arranged sequentially from top to bottom. Multiple spray nozzles are evenly distributed on the surfaces of the second and first transmission pipes. The surface of the second transmission pipe is disconnected relative to the top of the spray nozzles, and a movable sleeve is embedded in the inner side of the disconnection. Annular grooves are symmetrically formed at both ends of the movable sleeve. Through the designed movable sleeve, the angle of the drain outlet can be directly adjusted, with a 360° adjustment range, thus greatly reducing its limitations. Furthermore, it eliminates the need for multi-angle adjustable spray nozzles, reducing production costs. The designed sealing ring and rubber ring ensure a tight connection, preventing leakage and guaranteeing stable operation.

[0004] The existing transformer cooling spray structure has a large nozzle spacing between the pipes, which limits the spray range and makes it impossible to cool the transformer quickly. Therefore, it does not meet the current requirements, and a transformer rapid cooling spray device is proposed. Utility Model Content
