Abstract

The utility model discloses a kind of mounting structure of current transformer, comprise housing, current transformer, cylinder; Described cylinder is vertically fixed on the base plate of housing, and current transformer to be socketed on cylinder and to be fixed on the base plate of housing; Described current transformer has three, and three current transformers are that isosceles triangle is arranged.Because the utility model three current transformers are that isosceles triangle is arranged, the mutual interference between three current transformers can be offset completely, and can share zero-sequence transformer as required, have compact conformation, volume little, disturb little advantage.

Description

The mounting structure of current transformer

Technical field

The utility model relates to a kind of switchgear, particularly relates to a kind of mounting structure of current transformer.

Background technology

In switchgear, relate to the assembling of many parts.As shown in Figure 1, at present, traditional current transformer 91,92,93 is installed, side-by-side is mostly adopted to install, this traditional mounting means cannot offset three current transformers 91,92,93 each other mutual inductance produce interference, and the shell (base and cover) that cannot realize current transformer and zero-sequence transformer shares, volume is larger.

Summary of the invention

The purpose of this utility model is to provide a kind of mounting structure disturbing the current transformer of little, compact conformation.

For achieving the above object, technical solution of the present utility model is:

The utility model is a kind of mounting structure of current transformer, comprises housing, current transformer, cylinder; Described cylinder is vertically fixed on the base plate of housing, and current transformer to be socketed on cylinder and to be fixed on the base plate of housing; Described current transformer has three, and three current transformers are that isosceles triangle is arranged and is separately fixed on the base plate of housing.

The utility model also comprises a circular zero-sequence transformer; Described circular zero-sequence transformer is circular, is fixed on the lid of housing.

After adopting such scheme, because the utility model three current transformers are that isosceles triangle is arranged, mutual interference between three current transformers can be offset completely, and can share zero-sequence transformer as required, have compact conformation, volume little, disturb little advantage.

Below in conjunction with the drawings and specific embodiments, the utility model is further described.

Embodiment

As shown in Figure 2, the utility model is a kind of mounting structure of current transformer, comprises housing 1, three current transformers 2, three cylinders 3, circular zero-sequence transformer 4, wiring board 5, lids 6.

Described three cylinders 3 are arranged in isosceles triangle and are vertically fixed on the base plate of housing 1.Described current transformer 2 is in circular (as shown in Figure 4), and three current transformers 2 are socketed on three cylinders 3 respectively, forms isosceles triangle and arranges and be fixed on the base plate of housing 1.

Described wiring board 5 to be fixed in housing 1 and near housing 1 madial wall.

As shown in Figure 3, cover lid 6 on housing 1.

As shown in Figure 6, described circular zero-sequence transformer 4 is circular (as shown in Figure 5).When needs time, described circular zero-sequence transformer 4 is fixed on the lid 6 of housing

Emphasis of the present utility model is just: three cylinders are that isosceles triangle is arranged.

The above, be only the utility model preferred embodiment, therefore can not limit with this scope that the utility model implements, the equivalence namely done according to the utility model claim and description change with modify, all should still belong in scope that the utility model patent contains.

Claims

1. a mounting structure for current transformer, comprises housing, current transformer, cylinder; Described cylinder is vertically fixed on the base plate of housing, and current transformer to be socketed on cylinder and to be fixed on the base plate of housing; It is characterized in that: described current transformer has three, three current transformers are that isosceles triangle is arranged and is separately fixed on the base plate of housing.
