The housing of current transformer is generally shorter, and the creepage distance on so its surface is also shorter, so as to cause some potential safety problems.
Utility model content
The purpose of this utility model is to provide a kind of current transformer structure, passes through the side of the body to current transformer
The surface texture of wall is improved, to promote the creepage distance of the side wall of current transformer.
To reach above-mentioned technique effect, the specific technical solution of the utility model is as follows：
A kind of current transformer structure includes the body of rectangular parallelepiped structure, and accommodating chamber, institute are formed in the body
It states and connection guide rail is respectively equipped at the both sides of the edge of the upper surface of body, be respectively formed on the left side wall and right side wall of the body
Rear boss is respectively formed with wavy shirt rim on the front side wall and rear wall of the body, connects on the lower surface of the body
The installing plate of rectangle is connected to, the edge of the installing plate is equipped with several connecting screw holes.
In a specific embodiment, the baffle shape for the upper surface that the connection guide rail protrudes from the body by two pieces
Into,
In a specific embodiment, the lower end of the front side wall is formed with the first inclined-plane being inclined outwardly, the rear side
The lower end of wall is formed with intilted second inclined-plane.
In a specific embodiment, first inclined-plane is equipped with the wiring hole that several are connected with the accommodating chamber.
In a specific embodiment, the upper surface of the body is equipped with several bus bars.
Compared with prior art, the utility model it is no change current transformer length on the premise of, by
The sidewall surfaces of current transformer set the structures such as boss, shirt rim to extend the creepage distance of side wall, so as to improve electricity consumption peace
Quan Xing.
Description of the drawings
It, below will be to required practicality in embodiment in order to illustrate more clearly of the technical solution of the utility model embodiment

Body embodiment is described in further detail the utility model.
Shown in please referring to Fig.1, in a specific embodiment, current transformer provided by the utility model includes rectangular
The body of body structure is formed with accommodating chamber in the body, connection is respectively equipped at the both sides of the edge of the upper surface of the body
Guide rail 1, is respectively formed with boss 3 on the left side wall and right side wall of the body, on the front side wall and rear wall of the body point
Wavy shirt rim 4 is not formed with, and the installing plate 2 of rectangle, the edge of the installing plate 2 are connected on the lower surface of the body
Place is equipped with several connecting screw holes.Wherein：The accommodating chamber is used to install the electric components of current transformer, and the connection is led
Rail 1 is dielectrically separated from plate for connecting, to reduce electromagnetic interference of the ambient enviroment to current transformer, the boss 3, the shirt rim
The creepage distance of 4 side walls that can extend current transformer.
In the present embodiment, the baffle for the upper surface that the connection guide rail 1 protrudes from the body by two pieces is formed.Described
The upper surface of body is set there are two bus bar 6, and the connection guide rail 1 is located at the both sides of the bus bar 6.
In order to further enhance the front side wall of current transformer and the creepage distance of rear wall, in the present embodiment, before described
The lower end of side wall is formed with the first inclined-plane being inclined outwardly, and the lower end of the rear wall is formed with intilted second inclined-plane.
In the present embodiment, first inclined-plane is equipped with several wiring holes 5 connected with the accommodating chamber.It is connect through described
Current transformer can be connected by string holes 5 with other external electrical equipments.
The description with certain particularity detailed enough has been carried out to the utility model above.It is common in fields
It is to be understood by the skilled artisans that the description in embodiment was merely exemplary, in the true spirit without departing from the utility model and
All changes are made on the premise of scope should all belong to the scope of protection of the utility model.The utility model is claimed
Scope is defined by described claims rather than is limited by the foregoing description in embodiment.
