Abstract
The invention provides a kind of current transformer structure, it includes the body of rectangular parallelepiped structure, formed with accommodating chamber in the body, connection guide rail is respectively equipped with the both sides of the edge of the upper surface of the body, rear boss is formed respectively on the left side wall and right side wall of the body, wavy shirt rim is respectively formed with the front side wall and rear wall of the body, the installing plate of rectangle is connected with the lower surface of the body, the edge of the installing plate is provided with several connecting screw holes.Compared with prior art, the present invention is on the premise of the length of no change current transformer, and it in the sidewall surfaces of current transformer by setting the structures such as boss, shirt rim to extend the creep age distance of side wall, so as to improve electrical safety.
Description
Technical field
The present invention relates to field of electrical equipment, more particularly to a kind of current transformer structure.
Background technology
Current transformer is a kind of common electric device.Current transformer includes housing and installation made of insulating materials
In the electrical equipment of enclosure interior.Although housing is made up of insulator, in order to reduce the space shared by current transformer,
The housing of current transformer is general shorter, and the creep age distance on so its surface is also shorter, so as to cause certain potential safety hazard.
The content of the invention
It is an object of the invention to provide a kind of current transformer structure, it passes through the side wall of the body to current transformer
Surface texture is improved, with the creep age distance of the side wall of motor current transformer.
To reach above-mentioned technique effect, concrete technical scheme of the invention is as follows：
A kind of current transformer structure, it includes the body of rectangular parallelepiped structure, and the body is interior formed with accommodating chamber, institute
State and connection guide rail is respectively equipped with the both sides of the edge of the upper surface of body, formed respectively on the left side wall and right side wall of the body
Rear boss, wavy shirt rim is respectively formed with the front side wall and rear wall of the body, is connected on the lower surface of the body
The installing plate of rectangle is connected to, the edge of the installing plate is provided with several connecting screw holes.
In a specific embodiment, it is described to connect baffle plate shape of the guide rail by two pieces of upper surfaces for protruding from the body
Into,
In a specific embodiment, the lower end of the front side wall is formed with the first outward-dipping inclined-plane, the rear side
The lower end of wall is formed with intilted second inclined-plane.
In a specific embodiment, first inclined-plane is provided with the wiring hole that several are connected with the accommodating chamber.
In a specific embodiment, the upper surface of the body is provided with several bus bars.
Compared with prior art, on the premise of the length of no change current transformer, it passes through in electric current the present invention
The sidewall surfaces of transformer set the structures such as boss, shirt rim to extend the creep age distance of side wall, so as to improve electrical safety.
Brief description of the drawings
In order to illustrate the technical solution of the embodiments of the present invention more clearly, below by required practical attached in embodiment
Figure is briefly described, it should be evident that drawings in the following description are only some embodiments of the present invention, for this area
For those of ordinary skill, on the premise of not paying creative work, other accompanying drawings can also be obtained according to these accompanying drawings.
Wherein,
Fig. 1 is the structural representation of current transformer provided by the invention in a specific embodiment.
Embodiment
To make the above objects, features and advantages of the present invention, can be more obvious understandable, it is below in conjunction with the accompanying drawings and specific real
Applying mode, the present invention is further detailed explanation.
It refer to shown in Fig. 1, in a specific embodiment, current transformer provided by the invention includes cuboid knot
The body of structure, formed with accommodating chamber in the body, connection guide rail is respectively equipped with the both sides of the edge of the upper surface of the body
1, it is respectively formed with boss 3 on the left side wall and right side wall of the body, shape respectively on the front side wall and rear wall of the body
Into there is wavy shirt rim 4, the installing plate 2 of rectangle is connected with the lower surface of the body, the edge of the installing plate 2 is set
There are several connecting screw holes.Wherein：The accommodating chamber is used for the electric components for installing current transformer, the connection guide rail 1
Plate is dielectrically separated from for connecting, to reduce electromagnetic interference of the surrounding environment to current transformer, the boss 3, the shirt rim 4 are then
The creep age distance of the side wall of current transformer can be extended.
In the present embodiment, the connection guide rail 1 is formed by the baffle plate of two pieces of upper surfaces for protruding from the body.Described
The upper surface of body is provided with two bus bars 6, and the connection guide rail 1 is located at the both sides of the bus bar 6.
For the front side wall of further motor current transformer and the creep age distance of rear wall, in the present embodiment, before described
The lower end of side wall is formed with the first outward-dipping inclined-plane, and the lower end of the rear wall is formed with intilted second inclined-plane.
In the present embodiment, first inclined-plane is provided with several wiring holes 5 connected with the accommodating chamber.Connect through described
String holes 5, current transformer can be connected with other electrical equipments of outside.
The description with certain particularity detailed enough has been carried out to the present invention above.Ordinary skill in art
Personnel are it should be understood that what the description in embodiment was merely exemplary, before without departing from true spirit and scope of the present invention
Put make it is all change should all belong to protection scope of the present invention.Scope of the present invention is by described power
What sharp claim was defined, rather than limited by foregoing description in embodiment.
