Description

A theft-proof and noise-reducing high-frequency transformer

Technical Field

The invention belongs to the technical field of transformers, and in particular relates to an anti-theft and noise-reducing high-frequency transformer.

Background Art

A transformer is an electrical device used to change AC voltage. It consists of two or more coils and works on the principle of electromagnetic induction. Transformers are widely used in power transmission and distribution in power systems, power supply in various electronic equipment, and power regulation in industrial production. A high-frequency transformer refers to a transformer with a higher operating frequency, usually in the range of tens of kilohertz to hundreds of kilohertz. Due to the high operating frequency, high-frequency transformers adopt a more miniaturized design with small size and light weight, which is suitable for some occasions with high requirements on space and weight.

Existing transformers usually do not have anti-theft functions. If the transformer is placed outdoors, non-staff may forcibly steal the transformer, and the alarm cannot be sounded in time to remind the staff that the transformer has been stolen. At the same time, the transformer will generate mechanical vibrations and certain noise when working. The existing transformers do not have good sound insulation effects, causing noise pollution in the surrounding environment. The noise generated will have a negative impact on the quality of life of residents, causing complaints and dissatisfaction.
