Impact-resistant mutual inductor

Technical Field

The utility model relates to a current transformer technical field specifically is an impact-resistant mutual-inductor.

Background

The theoretical basis of the current transformer is electromagnetic induction, the current transformer generally comprises a closed iron core and a winding, rated current is used as a main parameter of the current transformer, the maximum current value which can be borne by the current transformer in an allowable working environment is meant, the traditional current transformer is poor in heat dissipation, and facilities for avoiding accidental short circuit between terminals are not arranged under the condition that a wiring terminal is exposed, so that the application range of the current transformer is limited. When the mutual inductor is installed on a vertical bus bar, the mutual inductor is easy to slide away from the bus bar and cannot be fastened after high temperature, low temperature and vibration caused by severe weather, thereby possibly causing current breakdown,
