Abstract

The invention discloses a voltage transformer. The voltage transformer comprises a body with an inner cavity, a voltage mutual inductance portion arranged in the inner cavity, and a connection piece which is arranged at a first end of the body, located on the exterior of the inner cavity, and used to connect a bus cable of an objective air inflation cabinet. By using the voltage transformer, the problem that an existing voltage transformer is high in overhauling and replacement difficultly in the prior art, and achieves the effects of reducing the overhauling and replacement difficultly of the existing voltage transformer, enlarging an application range of the existing voltage transformer and improving popularizing rate of the existing voltage transformer.

Description

technical field [0001] The invention relates to the field of electronic devices, in particular to a voltage transformer. Background technique [0002] In the prior art, the traditional electromagnetic transformer is dominant, but its insulation structure is complex, and there are inherent defects such as magnetic saturation and ferromagnetic resonance, small dynamic range, large volume and weight. Miniaturized design is the main direction of development now, but at this stage there are only miniaturized current transformers, and miniaturized voltage transformers are rare. If you want to take the voltage signal, you have to use a large transformer, such as the elbow type and the pressure bar type, which is very inconvenient to install. [0003] In recent years, a transformer in the form of an insulator has appeared. This resistance-dividing electronic voltage transformer is quite different from the traditional voltage transformer in terms of working principle, structure and ...
