Description

Technical Field

[0002] Transformer cabinet is a device specially used to install and protect power transformers. Its main function is to provide a safe environment to ensure the normal operation of power transformers and prevent adverse effects of the external environment. This type of equipment is usually installed outdoors or indoors.

[0003] For transformer cabinets installed outdoors, due to the large temperature changes throughout the year, heat dissipation windows are usually designed to maintain good heat dissipation in other seasons. However, in the cold weather in winter, cold air enters through the heat dissipation windows, which can easily cause frost on electrical equipment, thereby causing some low-temperature failure problems and affecting the normal operation of electrical equipment.

[0004] In order to deal with this problem, measures such as closing the heat dissipation windows are usually taken in winter to protect the electrical equipment in the transformer cabinet. However, this practice easily causes condensation when the hot air generated by the electrical equipment at work contacts the cold cabinet wall. The generation of condensation easily causes problems such as leakage or short circuit, thereby affecting the normal operation of the electrical equipment. For this reason, an outdoor transformer cabinet is proposed. Utility Model Content
