TECHNICAL FIELD

[0001] The present application relates to the technical field of transformer, in particular to a low-temperature-proof transformer protection device. BACKGROUND

[0002] Transformer refers to a device that uses electromagnetic induction to change the voltage of alternating current. Transformers can be divided into power transformers and special transformers according to their uses. Power transformers are mainly used in power transmission and distribution lines to change the voltage to meet the needs of different users. Special transformers are used in smelting, electro-processing, electric drive, communication, automatic control and other special fields. The main components of a transformer are the primary coil, the secondary coil and the core (magnetic core). The main functions of a transformer include voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc. Transformers are basic equipment for power transmission and distribution and are widely used in industry, agriculture, transportation and urban communities. Low-temperature-proof transformer protection devices refer to a series of protective measures and equipment designed specifically for transformers operating in low-temperature environments. The purpose is to prevent problems such as insulation performance degradation, oil solidification and mechanical component damage caused by low temperature, thereby ensuring the safe and stable operation of the transformer.

[0003] The heat supply port position of the low-temperature-proof transformer protection device currently used is fixed. When supplying heat to the transformer, the heat supply port directly blows on a certain component of the transformer, resulting in uneven temperature of the entire transformer. This cannot effectively heat the core components of the transformer. Moreover, the component directly blown by the heat supply port will overheat. Over time, the component directly blown by the heat supply port will be damaged. In severe cases, it may cause the transformer to stop working. SUMMARY
