Abstract
The utility model discloses a mutual inductor which comprises a mutual inductor main body. The mutual inductor main body comprises a magnetic core, a coil is wound around the magnetic core, the mutual inductor main body is located in a casing, the coil penetrates the casing to be connected with an external load through a wire, a primary terminal penetrates the magnetic core through a primary side wire through hole, and a wiring hole is formed in the primary terminal. The mutual inductor is simple in structure and convenient to use and has good electric performance.
Description
Technical field
The utility model relates to a kind of instrument transformer, belongs to the electric component field.
Background technology
Instrument transformer; especially current transformer is a kind of common electric component; the big current conversion that is used for primary side is flow through is the little electric current of secondary side; for measuring and the used for relay protection current device; therefore not only need to keep the good insulation performance ability between second siding ring and the primary side threading, also need to have good electric property to carry out current conversion.
Existing multiple instrument transformer all is absorbed in lifting electric insulation ability, has ignored the improvement to the electric conversion performance.
Summary of the invention
At the defective of prior art, the utility model discloses a kind of instrument transformer, by architecture advances, not only kept the good insulation performance performance, and good electric property.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of instrument transformer comprises current transformer body, and current transformer body comprises magnetic core, be surrounded with coil on the magnetic core, current transformer body is arranged in shell, and coil passes case body and is connected with external loading by lead-in wire, one time terminal passes magnetic core by the primary side through wires hole, and one time terminal is provided with wiring hole.
Further, for reinforced insulation, has the epoxide-resin glue sealant between described current transformer body and the case body.
By said structure, the insulation property of product have effectively been guaranteed.
In order to improve the current conversion performance, described magnetic core is the ultracrystallite magnetic core, includes but not limited to iron-base ultramicro-crystal magnetic core or cobalt-based ultracrystallite magnetic core.Compare with other materials, adopt characteristics such as the ultracrystallite magnetic core has high magnetic permeability, high squareness ratio, core loss is low, high-temperature stability is good.
Wherein, described case body is made by acrylonitrile-butadiene-styrene (ABS) plastics (ABS), has good ageing-resistant, insulation property.
Wherein, a described terminal is made by nickel plating oxygen-free copper, and performance is good, and electricity decreases low.
Description of drawings
Fig. 1 is the utility model instrument transformer profile;
Fig. 2 is the utility model instrument transformer front view.
Embodiment
With reference to the accompanying drawings 1,2, instrument transformer of the present utility model, current transformer body partly comprises ultracrystallite magnetic core 1, is surrounded with coil on the ultracrystallite magnetic core 1, coil passes ABS case body 2 and is connected with extraneous load by lead terminal 5; Has epoxide-resin glue sealant 7 between current transformer body and the case body.Terminal 3 of nickel plating oxygen-free copper passes magnetic core by primary side through wires hole 6, and one time terminal is provided with wiring hole 4.
Applicant's experiment confirm, above-mentioned instrument transformer has reached following technical indicator at least:
From as can be seen above-mentioned, instrument transformer of the present utility model has fabulous current conversion ability, and electricity decreases little.
