Description

A kind of integrated high pressure current transformer
Technical field
This utility model belongs to the technical field of electric measurement, specifically, relates to a kind of integrated high pressure current transformer.
Background technology
Current transformer is an electrical equipment critically important in power system; the effect of current transformer is that the high voltage in system, big electric current are changed into low-voltage, normalized current, is widely used the current measurement in AC electric power systems electrical equipment, electric energy metrical, signal sampling and Microcomputer Protection etc..During the use of current transformer, magnetic core coil can generate heat, but the coefficient of expansion of magnetic core coil is different from shell, seals according to gapless encapsulation type, then be unfavorable for the heat radiation of magnetic core coil and expand with heat and contract with cold.
Utility model content
For deficiency above-mentioned in prior art, this utility model provides a kind of integrated high pressure current transformer.
In order to achieve the above object, the solution that this utility model uses is: a kind of integrated high pressure current transformer, including 3 magnetic core coils and integral type insulation crust, 3 magnetic core coils are independently positioned in integral type insulation crust, integral type insulation crust includes the insulated vias running through magnetic core coil centre bore, the inner ring of magnetic core coil arranges inner ring space, the outer ring of magnetic core coil is provided with space, outer ring, inner ring space is provided with inner ring limited step, space, outer ring is provided with outer ring limited step;Being provided with the penetration pipe the most corresponding with magnetic core coil on integral type insulation crust, the external connection of magnetic core coil is drawn from penetration pipe.
Further, the end of penetration pipe is fixedly connected with coupling, and coupling includes connecting tube and nut, and nut is rotatably connected to connecting tube end.
Further, integral type insulation crust is provided with isolation projection.
Further, penetration pipe is provided with full skirt.
The beneficial effects of the utility model are; space, outer ring and inner ring space can be for the heat radiation of magnetic core coil and the offer headspaces that expands with heat and contract with cold; integral type insulation crust is internal to be connected with outside air by penetration pipe; improve radiating effect further; thus protect magnetic core coil, in the service life of swelling current transformer, integral type insulation crust can reduce the volume and weight of whole device; and easy to use, measure reliable.
