Abstract

The invention provides a ground transformer spraying and cooling system which comprises a transformer, a base supporting the transformer and a frame platform arranged on the surrounding ground of thetransformer. A circle of pressure pipeline is arranged on the frame platform and located on the periphery of the transformer and is communicated with a water supply mechanism, a walking mechanism corresponding to the pressure pipeline is arranged on the frame platform, an atomizing and spraying mechanism is arranged on the walking mechanism, a plurality of L-shaped connecting pipelines are vertically arranged on the pressure pipeline, the atomizing and spraying mechanism is matched with the connecting pipelines, a temperature monitoring mechanism corresponding to the transformer is arranged onthe pressure pipeline, and a solar power generating mechanism and an environment cooling mechanism are arranged on the frame platform. The ground transformer spraying and cooling system can automatically detect the temperature of the transformer and conduct atomizing and spraying cooling on a high-temperature area, can also increase the surrounding humidity of the transformer and indirectly reduce the temperature of the transformer, the safety of the transformer in a transformer substation in operation is improved, and stable power supply is ensured.

Description

technical field [0001] The invention relates to the technical field of transformer cooling protection, in particular to a spray cooling system and method for an above-ground transformer. Background technique [0002] The heat dissipation and cooling of power transformers during operation plays an important role in the safe operation of transformers. Common power transformers are mainly oil-immersed transformers, and the main heat dissipation components are radiators composed of multiple groups of fins connected by sheet-like heat sinks, which use air convection to naturally cool down and install fans at the bottom of the heat sinks. Cool down the heat sink by blowing air to speed up the air circulation, which can meet the operation requirements of the transformer under normal circumstances; In the case of load operation, the oil temperature in the transformer is high, and the original heat dissipation method cannot meet the requirements. In order to ensure the safe operatio...
