Technical Field

[0001] The invention relates to the technical field of transformers, in particular to an outdoor anti-theft transformer. Background Art

[0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are primary coil, secondary coil and iron core (magnetic core). Its main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. Transformers can be divided into distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers, box-type transformer test transformers, corner transformers, high current transformers, excitation transformers, etc.

[0003] In recent years, transformer thefts have occurred frequently, which requires the anti-theft property of transformers to be taken seriously. In order to further improve the anti-theft function of outdoor transformers, an outdoor anti-theft transformer is proposed. The box-type transformer is semi-buried as a whole. The ground box is made of concrete. A waterproof layer is arranged inside to effectively prevent water seepage. A rain shelter is arranged on the top to effectively prevent external rainwater from entering. It has a good waterproof effect. The transformer is lifted and lowered by electric lifting, so that the transformer needs a specific motor controller to open, which makes the transformer have a good anti-theft effect and is convenient for staff to inspect and maintain.
