Description

Technical Field

[0001] The present invention relates to the technical field of voltage transformers, and in particular to an electromagnetic voltage transformer device. Background Art

[0002] An electromagnetic voltage transformer is a high-voltage device that converts high voltage in the power grid into low voltage for easy monitoring and measurement. Structurally, a voltage transformer is a small-capacity, small-volume, high-voltage-ratio step-down transformer. Its basic principle is the same as that of a transformer, and it is also composed of a primary winding, a secondary winding, an iron core, lead wires, and an insulation structure. The working principle, structure, and connection method of an electromagnetic voltage transformer are the same as those of a transformer. The main difference is that the capacity of the voltage transformer is very small, usually only tens to hundreds of volt-amperes.

[0003] Existing voltage transformers use electromagnetic induction to achieve voltage change regulation, thereby achieving the purpose of circuit voltage control. However, they have the disadvantage of difficulty in heat dissipation. Moreover, since voltage transformers often adopt a wrapped structure, the coil is wrapped around the outer periphery of the iron core, which cannot achieve efficient connection and heat dissipation.
