Abstract

The utility model relates to the field of transformer, in particular to a novel current transformer, which comprises a P1 connector terminal, an L-type filter plate, a primary winding, a voltage-equalizing net, a secondary outlet terminal, a secondary winding, a P2 connector terminal, an epoxy resin, a substrate and an inserted element, wherein the P1 connector terminal is welded with the L-type filter plate and is connected to the primary winding; the primary winding passes through the secondary winding and is welded on the P2 connector terminal after being wound for cored circles; an enamelled wire is uniformly wound on an iron core so as to form the secondary winding; the outlet wire of the secondary winding is respectively welded on the secondary outlet terminal according to the polarity and the identification of the secondary outlet terminal is confirmed according to the winding number and the ratio of transformation; the shielding layers of the secondary winding and voltage-equalizing net are both connected to the substrate through the inserted element; and the epoxy resin is once poured in the current transformer.

Description

A kind of New type of current instrument transformer
Technical field
The utility model relates to the power transformation field, relates to a kind of New type of current instrument transformer specifically.
Background technology
Similar current transformer product width up and down is the same substantially, and cluster parachute is concentrated, and instrument transformer is installed in the cabinet, and the spacing between phase and phase is shorter, has certain potential safety hazard during use.In order to overcome the above problems, need a kind of new bigger current transformer of alternate creepage distance of development to use safely with assurance.
Summary of the invention
In view of the defective that prior art exists, the purpose of this utility model is that a kind of New type of current instrument transformer will be provided.Solve the partial discharge problem of current transformer, improve the useful life of current transformer.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of New type of current instrument transformer comprises P1 binding post, L type rebound, winding, equalizing lattice, secondary outlet terminal, secondary winding, P2 binding post, epoxy resin, base plate, inserts.The P1 binding post welding L type rebound of described New type of current instrument transformer connects a winding, and one time winding passes secondary winding, and after meeting the punching number of turn, is welded on the P2 binding post; The enamelled wire uniform winding constitutes secondary winding on iron core, the outlet of secondary winding is welded on the secondary outlet terminal respectively according to polarity and according to winding quantity and no-load voltage ratio situation, determines secondary outlet terminal sign; The screen of secondary winding all links to each other with base plate by inserts with the screen of equalizing lattice; The inner once-cast epoxy resin of current transformer.
The profile of described current transformer is designed to trapezium structure from top to bottom, and cluster parachute evenly distributes.
The inside of described current transformer is added with screening arrangement.
Described current transformer is a full-closed structure.
Secondary winding in the described current transformer is circular.
Be provided with equalizing lattice in the described current transformer.
The beneficial effects of the utility model are a kind of New type of current instrument transformers, comprise P1 binding post, L type rebound, winding, equalizing lattice, secondary outlet terminal, secondary winding, P2 binding post, epoxy resin, base plate, inserts.The P1 binding post welding L type rebound of described New type of current instrument transformer connects a winding, and one time winding passes secondary winding, and after meeting the punching number of turn, is welded on the P2 binding post; The enamelled wire uniform winding constitutes secondary winding on iron core, the outlet of secondary winding is welded on the secondary outlet terminal respectively according to polarity and according to winding quantity and no-load voltage ratio situation, determines secondary outlet terminal sign; The screen of secondary winding all links to each other with base plate by inserts with the screen of equalizing lattice; The inner once-cast epoxy resin of current transformer.The instrument transformer appearance is designed to trapezium structure from top to bottom, and cluster parachute evenly distributes, and has increased alternate creepage distance, even external electric field.Inside is added with screening arrangement simultaneously, has optimized properties of product, has solved the partial discharge problem.
