The interpolar heat dissipation device comprises connecting plates, a heat dissipation plate, a mounting hole 1 and a mounting holes 2; the connecting plates are fixed at the positive pole and the negative pole of the direct current molded case circuit breaker through bolts; the heat dissipation plate is located on the connecting plates and is fixed to the connecting plates through bolts; the whole heat dissipation plate is of a rectangular grid-type structure; the mounting hole 1 and the mounting holes 2 are formed at two corresponding corners of the heat dissipation plate; six to ten grids on the heat dissipation plate exist; and the whole heat radiating plate is made of aluminum alloy. The interpolar heat dissipation device of the utility model has the advantages of simple structure, good heat dissipation performance and low cost. With the interpolar heat dissipation device adopted, product performance can fully meet temperature rise requirements of direct current molded case circuit breaker interpolar connection and a circuit breaker.
Description
Technical field
The utility model belongs to dynamo-electric manufacture field, particularly a kind of interpolar heat abstractor of direct current breaker of plastic casing.
Technical background
On market, the general basic structure of direct current breaker of plastic casing is identical with AC circuit breaker, just extinguishes considering that direct-current arc is more difficult, and arc control device internal structure has difference.The mode of connection is positive and negative terminals because direct current only has, therefore DC circuit breaker interpolar need to have gusset piece to be first connected in series.Like this, two-stage is serially connected in gusset piece two terminated lines place has contact resistance and produces fever phenomenon.Depend merely on gusset piece heat radiation, because length is short, the area of dissipation temperature rise requirement that causes temperature rise not reach national regulation less than normal, and sometimes also can be because of the too high initiating failure of temperature rise.
Utility model content
for overcoming above-mentioned defect, the technical problems to be solved in the utility model is to provide a kind of simple in structure, direct current breaker of plastic casing interpolar heat abstractor that heat dispersion is good.
An interpolar heat abstractor for direct current breaker of plastic casing, this heat abstractor comprises gusset piece, heating panel, installing hole one, installing hole two; Described gusset piece is bolted on positive and negative the two poles of the earth of direct current breaker of plastic casing; Heating panel is positioned at gusset piece top, by bolted on gusset piece; Described whole heating panel is rectangle grid slice structures, is provided with installing hole one, installing hole two at its corresponding two jiaos; On heating panel, the quantity of grid sheet is 6～10.
Described whole heating panel is made up of aluminium alloy.
When on described heating panel, the quantity of grid sheet is 9, radiating effect is best.
The utility model heat abstractor is not only simple in structure, and heat dispersion is good, but also with low cost, makes properties of product fully meet the temperature rise requirement of the connection of DC circuit breaker interpolar and circuit breaker.
Brief description of the drawings
Fig. 1 is the connection diagram of the utility model heat abstractor and direct current breaker of plastic casing;
Fig. 2 is the structural representation of the utility model heat abstractor.
Embodiment
?below in conjunction with accompanying drawing, the utility model is described in further detail.
The positive pole of direct current breaker of plastic casing taps into line end, and negative pole picks out line end, and electric current is flow to by end of incoming cables, and leading-out terminal flows out.The gusset piece at positive and negative the two poles of the earth of existing direct current breaker of plastic casing is to be fixed by screws on the positive and negative electrode of circuit breaker, therefore has larger contact resistance at wiring point, produces fever phenomenon, affects product quality.
As shown in Figure 1 and Figure 2, the situation that the utility model in use produces according to product, has designed a kind of interpolar heat abstractor of direct current breaker of plastic casing, and this heat abstractor comprises gusset piece 1, heating panel 2, installing hole 1, installing hole 24.Gusset piece 1 is bolted on positive and negative the two poles of the earth of direct current breaker of plastic casing; Heating panel 2 is positioned at gusset piece 1 top, by bolted on gusset piece 1.Whole heating panel 2 is rectangle grid slice structures, is provided with installing hole 1, installing hole 24, for heating panel 2 is fixed on to gusset piece 1 at its corresponding two jiaos.On heating panel 2, the quantity of grid sheet is 6～10.Whole heating panel 2 is made up of aluminium alloy.The utility model heat abstractor is applicable to positive and negative the two poles of the earth of direct current breaker of plastic casing.
The utility model has filled aluminium alloy heating panel 2 on gusset piece 1, can increasing heat radiation area, and rapidly by the grid sheet heat radiation on heating panel 2.After heat balance, the temperature rise of the gusset piece 1 that DC circuit breaker exposes can meet GB requirement, and product quality is guaranteed.
