Abstract
The utility model discloses a feed -through current transformer, it includes shell, inner shell, iron core, locating hole, participates in, and the iron core is located the shell, and the inner shell is located between iron core and the shell, the locating hole, participates in the bottom that all is located the shell. The utility model discloses a fully enclosed shell and inner shell do not have the exerted problem of iron core, put forward the high insulating ability.
Description
Technical field
The utility model relates to a kind of instrument transformer, particularly relates to a kind of straight-through current transformer.
Background technology
The effect of current transformer converts big current to small area analysis, to realize the functions such as measurement, system protection and Systematical control.The structure of ordinary electric current mutual-inductor is comparatively simple, is made up of winding, secondary winding, skeleton, iron core and a housing etc. of mutually insulated.Its operation principle and transformer are substantially identical, the number of turn of a winding is less to be directly series in power circuit, when a load current is by a winding, create alternating flux induction, the secondary current reduced in proportion is created in secondary winding, the number of turn of secondary winding is more, and connecting with secondary loads such as instrument, relay, transmitters forms closed-loop path.The structure of straight-through current transformer is slightly different from ordinary electric current mutual-inductor, a winding do not established by straight-through current transformer, by the current carrying conductor through current transformer core window as a winding, in secondary winding, produce the secondary current reduced in proportion, connecting with secondary load forms closed-loop path.
There is following problem in existing current transformer, and one, the problem of insulation property relative mistake, iron core exposure is only by adopting the method for adhesive tape parcel to reach insulating requirements.Two, there is the problem that production efficiency is low, the mode that encapsulate band can only be walked by hand on the iron core arm closed carries out the operation of encapsulate band, and cannot use automation equipment, therefore production efficiency is low.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of straight-through current transformer, its problem not having iron core to expose, and improves insulation property.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of straight-through current transformer, it is characterized in that, it comprises shell, inner casing, iron core, location hole, pin, iron core is positioned at shell, inner casing is between iron core and shell, and location hole, pin are all positioned on the bottom of shell.
Preferably, the top of described shell is provided with a projection.
Positive progressive effect of the present utility model is: the utility model adopts totally enclosed shell and inner casing, does not have the problem that iron core exposes, and improves insulation property.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model straight-through current transformer.
Embodiment
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model straight-through current transformer comprises shell 1, inner casing 2, iron core 3, location hole 4, pin 5, and iron core 3 is positioned at shell 1, and inner casing 2 is between iron core 3 and shell 1, and location hole 4, pin 5 are all positioned on the bottom of shell 1.The top of shell 1 is provided with a projection 6, and projection is convenient to be engaged with other elements.
The utility model adopts totally enclosed shell and inner casing, does not have the problem that iron core exposes, and improves insulation property.The utility model is without the need to encapsulate band on iron core, as long as simply buckle shell, produce not only simple but also speed is fast, improved efficiency clearly.Location hole conveniently positions.
Above-described specific embodiment; the technical problem of solution of the present utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
Claims (2)
