[0002] The waterproof transformer is a transformer with waterproof (moisture-proof / rain-proof) function. It has a special protective shell (cover), and the internal transformer is subjected to potting treatment (generally using heat-conducting epoxy resin as the potting material). It can cope with harsh environments such as high temperature, humidity, rain, and water immersion. It has a high IP protection level. The transformer can be divided into power transformers, test transformers, instrument transformers, and special-purpose transformers. The power transformer is a necessary device for power transmission and distribution and power user distribution. In the production of waterproof transformers, the waterproof performance of the transformer needs to be tested to determine its waterproof level and ensure the quality of the transformer.

The transformer to be detected is placed on the top of the placement plate, and the water is sprayed on the transformer through the spray head on the spray pipe to simulate the outdoor rain environment. The weighing sensor is set to weigh the change before and after the transformer is sprayed with water to detect the waterproof ability. The drive mechanism drives the rotating column to rotate to make the transformer rotate on the top of the placement plate, and the lifting mechanism makes the movable pipe reciprocatingly ascend and descend during spraying, so that the surrounding of the transformer can be fully sprayed, and the waterproof ability of the transformer in the outdoor environment can be more accurately detected.
