Abstract
The utility model discloses a mutual inductor which comprises varnished wires, a shell body and silicon steel sheets. The varnished wires are twined on a coils frame and by insulated rubber tapes. The shell body is of a circle structure and paralleled with the coils frame in an axial direction, multilayer silicon steel sheets are arranged in the shell body, the outsides of the silicon steel sheets are covered by the insulated rubber tapes, the coils frame is arranged on a base and the bottom of the base is provided with pins. The mutual inductor is simple in structure, small in size, high in output accuracy, convenient to install and can be directly plugged on the circuit board.
Description
Technical field
The utility model relates to a kind of instrument transformer, belongs to the instrument transformer technical field.
Background technology
Instrument transformer is the equipment of scaling transformation voltage or electric current.Its function mainly is that high voltage or large electric current scaling transformation are become standard low-voltage (100V) or the little electric current of standard (5A or 1A all refer to rated value), in order to 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.General instrument transformer volume is larger, and output accuracy is low, installs simultaneously inconvenient.
Summary of the invention
The utility model proposes a kind of instrument transformer, in order to address the above problem, this instrument transformer volume is little, and output accuracy is high, the circuit board of can directly pegging graft.
For realizing this purpose, the structure that the utility model adopts is: a kind of instrument transformer comprises enamelled wire, silicon steel sheet and housing, enamelled wire is wrapped on the bobbin, and described housing is annular, and bobbin is positioned at housing central authorities, axially parallel with bobbin, be provided with silicon steel sheet in the housing.
Described enamelled wire and the silicon steel sheet outside all are enclosed with insulating tape.
Described insulating tape is polyester film adhesive tape.
Described bobbin is arranged on the base, and the base bottom is provided with many stitch.
Its beneficial effect is: this kind instrument transformer small volume simple in structure, output accuracy is high, and can directly be inserted on the circuit board, and is easy for installation.
