Electricity larceny prevention voltage transformer

The utility model relates to the technical field of mutual inductors, in particular to an electricity larceny prevention voltage transformer which comprises a base, mutual inductor bodies and supporting frames, a plurality of cushion blocks are fixedly installed above the base, the mutual inductor bodies are fixedly installed at the top ends of the cushion blocks, and the supporting frames are fixedly connected to the outer sides of the mutual inductor bodies. The top ends of the mutual inductor bodies are fixedly connected with iron cores, and the outer sides of the iron cores are fixedly sleeved with insulators. According to the electricity larceny prevention voltage transformer, the baffle and the lower through hole can be driven by the upper through hole to be folded, then the baffle is fixed between the lower through hole and the upper through hole through the lock catch of the anti-theft lock, and when the anti-theft lock needs to be used, the baffle can be opened to use an internal connecting wire afte
