Abstract

A small mutual inductor comprises a supporting base, a connecting groove is formed in the upper surface of the supporting base, a damping rotating shaft is connected into the connecting groove, a rotating disc is in key connection with the outer side of the damping rotating shaft, and a clamping block is fixedly connected to the rotating disc. The clamping block is clamped in groove, the groove isformed in the corner of a connecting ring, the connecting ring is fixedly connected to the lower surface of an outer cover, and a cover ring is embedded in the outer side of the outer cover. According to the small-sized mutual inductor, the turn ratio of the first coil to the second coil can be conveniently adjusted; therefore, the small mutual inductor can be suitable for various conditions; thelimitation of use caused by the constant turn ratio of the first coil to the second coil in the conventional small-sized mutual inductor is avoided; the mutual inductor is convenient to disassemble and assemble, so that the mutual inductor is convenient to overhaul and maintain, and the problem that bolts are corroded and inconvenient to disassemble and assemble after an existing small mutual inductor is used for a long time due to the fact that the existing small mutual inductor is fixed through the bolts is solved.

Description

Technical field [0001] The invention relates to the technical field of transformers, in particular to a small-sized transformer. Background technique [0002] A transformer is a type of transformer, which includes a current transformer and a voltage transformer. The transformer can turn high voltage into low voltage or large current into small current, which is used for measurement or protection system. The high voltage is turned into a low voltage to facilitate the connection with the measuring instrument and equipment, so as to prevent the excessive voltage from burning the measuring instrument and equipment, and the transformer can isolate the high voltage, which helps to protect the personal safety of the user. [0003] However, the existing small-scale transformer is not convenient to adjust the ratio between the coils. Because the coil ratio of the existing small-scale transformer is constant, it can only convert a constant high voltage into a constant low voltage. The high ...
