Abstract

The utility model discloses a multipurpose mutual -inductor, including a magnetic core and wire winding, the wire winding is divided into wire winding of first group and the wire winding of second group, when secondary winding's output termination two wire -wound terminals in the first group or when two wire -wound terminals were organized to the second, this mutual -inductor was as 10001 current transformer, output termination as secondary winding a wire -wound terminal in the first group with a wire -wound terminal in the second group, when two other terminals were established ties, this mutual -inductor was as 20001 current transformer, when a set of wire winding winds when regarding as secondary winding as primary winding, another group, and this mutual -inductor is as voltage transformer. The utility model discloses simple structure, can be nimble be applicable to power industry, and the material is the material of selling on the market, low cost.

Description

A kind of multipurpose transformer

Technical field

This utility model relates to technical field of electronic components, especially a kind of current/voltage transformer.

Background technology

The transformer used on electric power at present is fixing no-load voltage ratio, or although the number of turn is variable but is only limited to as voltage transformer or current transformer, transformer type can not be realized and the number of turn is the most variable, along with the raising of hardware integration degree, reality more and more occurs the situation needing to use multiduty transformer.

Summary of the invention

For above-mentioned weak point of the prior art, this utility model provides a kind of multifunctional mutual-inductor, both can be used as voltage transformer, and can be used as again current transformer, variable as number of turn during current transformer.

A kind of multipurpose transformer, including a magnetic core and coiling thereof, described coiling is divided into first group of coiling and second group of coiling, first group of coiling and second group of coiling are the coil of 1000 circles, it is evenly distributed on described magnetic core, when the output of Secondary Winding terminates two terminals of two terminals of described first group of coiling or described second group of coiling, this transformer is as 1000/1 current transformer；When the output of Secondary Winding terminates a terminal and a terminal of described second group of coiling of described first group of coiling, and during two other terminal series-shunt, this transformer is as 2000/1 current transformer；When described one group of coiling is as a winding, when another group coiling is as Secondary Winding, this transformer is as voltage transformer.

It is surrounded by cabinet outside described magnetic core.

Described cabinet outer bottom draws four stitch, two stitch of Base top contact.

A through hole is had in the middle of described cabinet.When multipurpose transformer uses as current transformer, one time winding passes from through hole and is wound on the cabinet of magnetic core, and the number of turn is 1 circle.

This utility model can use as inductance transformer and voltage transformer according to actual needs, during as inductance transformer, can realize again 1000/1 and 200,0/1 two kind of no-load voltage ratio, its simple in construction, can be flexibly be applicable to power industry, and material is the material of commercial type, with low cost.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.

As it is shown in figure 1, the present embodiment internal threads is divided into two groups, it is first group of coiling between terminal 1,2, is 1000 circles, be second group of coiling between terminal 3,4, be also 1000 circles, rotating around on magnetic core.

When first group of coiling is as a winding, second group of coiling is as the second winding, and now transformer uses as voltage transformer.

When passing and be wrapped in wire through hole b from Fig. 2 on cabinet a, transformer uses as current sensor, the most again can be in two kinds of situation: with arbitrary group of coiling as Secondary Winding, i.e. terminal 1,2 or terminal 3,4 connects load, and transformer is the current transformer of 1000/1；If two groups of coilings are cascaded, other two terminal connects load, then transformer is the current transformer of 2000/1.

Cabinet a it is surrounded by outside magnetic core, the flame-proof environmental protection cabinet being made up of PBT material, magnetic core and enamel-covered wire effectively can be kept apart, isolate pressure effect obvious.

Drawing 4 stitch bottom cabinet a, terminal 1,2,3,4 can be connected to bottom stitch c by wire respectively, uses for flexible, and 2 stitch are also drawn at top.

Technological means disclosed in this utility model scheme is not limited only to the technological means disclosed in above-mentioned embodiment, also includes the technical scheme being made up of above technical characteristic combination in any.
