Abstract

A mutual inductor with an anti-electromagnetic interference insulating casing relates to a mutual inductor and comprises a mutual inductor main body and an anti-electromagnetic interference insulating casing, wherein the mutual inductor main body is composed of a sensing iron core and a coil wound on the sensing iron core. The mutual inductor is characterized in that an insulating threading device is further arranged on the mutual inductor main body, a wiring terminal is further arranged on the anti-electromagnetic interference insulating casing, and thread ends of a first winding and a second winding of the coil penetrate through the insulating threading device to be electrically connected with the wiring terminal. The mutual insulator has the advantages that the mutual inductor main body is arranged in the anti-electromagnetic interference insulating casing, so that electromagnetic interference on surrounding electric appliances caused by the mutual inductor can be effectively reduced, and the whole device is simple in structure, convenient in wiring and good in safety.

Description

A kind of instrument transformer with anti-electromagnetic interference insulation crust
Technical field
The utility model relates to the instrument transformer technical field, especially relates to a kind of instrument transformer with anti-electromagnetic interference insulation crust.
Background technology
Instrument transformer (instrument transformer) is the equipment of scaling transformation voltage or electric current.Its function mainly is that high voltage or big electric current scaling transformation are become standard low-voltage (100V) or the little electric current of standard (5A or 10A all refer to rated value), so that realize standardization, the miniaturization of measuring instrument, protection equipment and automatic control equipment.Instrument transformer also can be used to separate high-voltage system simultaneously, to guarantee the safety of the person and equipment, the equipment of scaling transformation voltage or electric current.
Instrument transformer on the market generally lacks electromagnetic interference equipment, and other electric equipments bring electromagnetic interference around often giving, thereby influence the work of other electric equipments.
