The invention relates to a self-coupling transformer, which consists of an iron core, a coil and a shell, is simple, practical, low in cost and adaptable to the service range thereof and overcomes the defects of existing self-coupling transformers. Since temperature controlling devices are added, the self-coupling transformer can avoid and reduce overload, overcurrent caused by various reasons and various accidents caused by improper maintenance and use.
Description
1. Technical field [0001] The invention relates to a transformer, in particular to an autotransformer. 2. Background technology [0002] Autotransformer is a commonly used electrical equipment, and its safety is particularly important. At present, autotransformers have defects such as overload, overcurrent and improper use and maintenance in use, causing various accidents. 3. Contents of the invention [0003] In order to overcome the deficiencies and defects of the prior art, the present invention provides an autotransformer, which can effectively prevent accidents caused by overload and overcurrent of the autotransformer due to various reasons. [0004] The purpose of the present invention is achieved like this: [0005] An autotransformer of the present invention is composed of an iron core, a coil and a shell, and is characterized in that a temperature control device is installed between turns of the coil, and an alarm device is installed on a control board. It is ch...
