Abstract

The utility model relates to the field of power transformation, in particular to a totally-enclosed type medium voltage current transformer. A P1 connecting terminal 1 is welded on an L-shaped connecting plate and connected with a primary coil; the primary coil passes through a secondary coil; after the number of center passing turns is satisfied, the primary coil is welded on a P2 connecting terminal; the secondary coil is formed by uniformly winding an enamel covered wire on an iron core; lead-out wires of the secondary coil are respectively welded on the secondary terminal according to polarities; marks of the secondary terminal 4 are defined according to the quantity of coils and transformation ratio conditions; epoxide resin is cast inside the current transformer; a current transformer body is fixed on a bottom plate; two plate-shaped lateral wings are arranged at the upper part of the current transformer; and the current transformer adopts a totally-enclosed structure. When the totally-enclosed type medium voltage current transformer is installed in a switch cabinet, baffles are not required to be installed, so that the installation steps are greatly simplified, and the work efficiency and the use safety are improved.

Description

Piezoelectricity current transformer in a kind of totally enclosed type
Technical field
The utility model relates to the power transformation field, relates to piezoelectricity current transformer in a kind of totally enclosed type specifically.
Background technology
Current transformer is the main electric component in the switch cubicle.Based on Electrical Safety, when present employed current transformer is installed side by side, between current transformer, dividing plate to be installed in switch cubicle.It is more loaded down with trivial details to make that like this installation of switch cubicle becomes.Install for convenience, developed a kind of current transformer that has flank.When this current transformer is installed in switch cubicle, do not need to install dividing plate, thereby simplified installation steps greatly, increase work efficiency and safe in utilization.
Summary of the invention
In view of the defective that prior art exists, the purpose of this utility model is that piezoelectricity current transformer in a kind of totally enclosed type will be provided, and improves the fail safe of current transformer use and the simplification of installation.
The technical scheme that its technical problem that solves the utility model adopts is: piezoelectricity current transformer in a kind of totally enclosed type comprises P1 binding post, primary winding, secondary coil, secondary terminal, base plate, epoxy resin, P2 binding post, L type connecting plate and flank.The P1 binding post 1 of piezoelectricity current transformer welding L type connecting plate connects primary winding in the described totally enclosed type, and primary winding passes secondary coil, meet the punching number of turn after, be welded on the P2 binding post; Secondary coil is made of on iron core the enamelled wire uniform winding, and the outlet of secondary coil is welded on the secondary terminal respectively according to polarity and according to winding quantity and no-load voltage ratio situation, determines secondary terminal 4 signs; The inner casting epoxy resin of current transformer; The device body is fixed on the base plate; Be provided with two template flanks on the top of described current transformer; Described current transformer is a full-closed structure.
Described secondary coil is a circular ring.
The height of described two template flanks is higher than 150mm.
The beneficial effects of the utility model are: the P1 binding post 1 of piezoelectricity current transformer welding L type connecting plate connects primary winding in the described totally enclosed type, and primary winding passes secondary coil, meet the punching number of turn after, be welded on the P2 binding post; Secondary coil is made of on iron core the enamelled wire uniform winding, and the outlet of secondary coil is welded on the secondary terminal respectively according to polarity and according to winding quantity and no-load voltage ratio situation, determines secondary terminal 4 signs; The inner casting epoxy resin of current transformer; The device body is fixed on the base plate; Be provided with two template flanks on the top of described current transformer; Described current transformer is a full-closed structure.When the utility model is installed, do not need to install dividing plate in switch cubicle, thereby simplified installation steps greatly, increase work efficiency and safe in utilization.
