Abstract
The utility model relates to the low-voltage apparatus field, in particular to a nano-crystalline mutual inductor, which comprises an iron core, a coil, a shell and a lead, wherein the iron core is wrapped on the coil; the iron core and the coil are both installed inside the shell; the lead is connected with the coil and extends to the bottom of the shell; the outer part of the coil is wrapped by potting adhesive; and the material of the potting adhesive is epoxy resin. The material of the iron core adopts nano-crystalline, and the outer part of the coil is sealed and insulated by the epoxy resin, thereby obtaining better sealing property and insulativity as well as higher magnetic conductivity and sensitivity.
Description
Technical field
The utility model relates to the low-voltage electrical apparatus field, especially a kind of nanocrystalline instrument transformer.
Background technology
To be big electric current that primary side is flow through be converted to the little electric current of certain ratio at secondary side with instrument transformer, for measuring and the electric device of used for relay protection; The iron core of existing instrument transformer is common iron and steel, between coil and the shell is to adopt insulating case to isolate, and connects insecurely, and sealing is poor, causes that magnetic permeability is low, sensitivity is low.
Summary of the invention
For the coil that overcomes existing instrument transformer be connected with shell insecure, the deficiency that magnetic permeability is low, sensitivity is low, the utility model provides a kind of nanocrystalline instrument transformer.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of nanocrystalline instrument transformer, comprise iron core, coil, shell and lead-in wire, coil is rolled on the iron core, and iron core and coil are all installed in the enclosure, lead-in wire is connected on the coil, extends to the bottom of shell.
The external packets of coil is wrapped with casting glue.
The material of casting glue is an epoxy resin.
The beneficial effects of the utility model are, the iron core material adopts nanocrystalline, and coil is outside to adopt the epoxy sealing insulation, not only has better sealing and insulating properties, and makes magnetic permeability higher, and sensitivity is higher.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a schematic diagram of the present utility model.
1. iron cores among the figure, 2. coil, 3. shell, 4. lead-in wire, 5. casting glue.
Embodiment
As Fig. 1 is schematic diagram of the present utility model, a kind of nanocrystalline instrument transformer, comprise iron core 1, coil 2, shell 3 and go between 4, coil 2 is rolled on the iron core 1, iron core 1 and coil 2 all are installed in the shell 3, lead-in wire 4 is connected on the coil 2, and lead-in wire 4 extends to the bottom of shell 4, and iron core 1 material is nanocrystalline.The external packets of coil 2 is wrapped with casting glue 5.The material of casting glue 5 is an epoxy resin.
Evenly coiling of 360 degree on iron core 1 earlier forms coil 2; Two the end of a thread with coil 2 are fixed on two lead-in wires 4 then, and add tin; The coil 2 that will contain two lead-in wires 4 again is contained in the transformer casing 3; Final online circle 2 surface parcel casting glues 5 separate coil 2 and shell 3.
