Abstract
The utility model belongs to a female device of arranging, concretely relates to improve female device of arranging of conductor current distribution for current distribution including mother row body, mother arranges the body and is the female row of rectangle, and rectangle mother row both ends head is seted up flutedly along length direction, the width of recess is 3 millimeters, and recess length is greater than the spaced apart fixed orifices of being connected with electrical components or female row that is equipped with in both sides of the female faying surface length of arranging of rectangle, recess. The utility model discloses a female both ends first faying surface department of arranging sets up flutedly along length direction at the rectangle for female surface area increase of arranging faying surface department, the event has reduced the current density of female row of faying surface department, thereby reaches and improve the current -carrying ability, that is to say under the unchangeable condition of current -carrying, has reduced the temperature rise of conductor connecting position, has solved female current -carrying of arranging in using of rectangle and the problem of generating heat.
Description
Technical field
This utility model belongs to the bus-bar device for CURRENT DISTRIBUTION, is specifically related to a kind of bus-bar device improving conductor current distribution.
Background technology
In ac metal closing switch gear, use is bolted to connection between rectangle busbar and electric elements, busbar and busbar more at present, is inevitably present the phenomenon of electric conductor connecting portion heating.Principle according to CURRENT DISTRIBUTION kelvin effect, conductor current is distributed in conductive surface, so, recessing at the busbar faying surface that this patent relates to, increase surface area during busbar overlap joint, improve current carrying area and the area of dissipation of busbar, reduce the electric current density at busbar faying surface, thus effectively reduce the purpose of electric conductor connecting portion heating.
Summary of the invention
The purpose of this utility model seeks to provide a kind of current carrying area that improve busbar and area of dissipation, solves the bus-bar device of electric conductor connecting portion heating problem.
This utility model is achieved through the following technical solutions:
A kind of bus-bar device improving conductor current distribution, including busbar body, busbar body is rectangle busbar 1, rectangle busbar 1 two ends offers groove 2 along its length, the width of described groove 2 is 3 millimeters, groove 2 length is more than the faying surface length of rectangle busbar 1, and the both sides of groove 2 are spaced apart is provided with the fixing hole 3 being connected with electric elements or busbar.
Compared with prior art, the beneficial effects of the utility model are:
The purpose of this utility model is for existing bus-bar device, a kind of current carrying area improving busbar and the bus-bar device of area of dissipation are provided, by offering groove along its length at rectangle busbar two ends faying surface, surface area at busbar faying surface is increased, therefore reduce the electric current density at busbar faying surface, thus reach to improve current capacity, that is in the case of current-carrying is constant, reduce electric conductor connecting portion temperature rise, solve the current-carrying during rectangle busbar uses and heating problem.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1. rectangle busbar, 2. groove, 3. fixing hole.
Detailed description of the invention
Below this utility model is described further:
As shown in Figure 1, a kind of bus-bar device improving conductor current distribution, including busbar body, busbar body is rectangle busbar 1, rectangle busbar 1 two ends offers groove 2 along its length, the width of described groove 2 is 3 millimeters, and groove 2 length is more than the faying surface length of rectangle busbar 1, and the both sides of groove 2 are spaced apart is provided with the fixing hole 3 being connected with electric elements or busbar.
This utility model is by offering groove 2 along its length at rectangle busbar 1 two ends faying surface, surface area at rectangle busbar 1 faying surface is increased, therefore reduce the electric current density at rectangle busbar 1 faying surface, thus reach to improve current capacity, that is, in the case of current-carrying is constant, electric conductor connecting portion temperature rise is reduced.
