Description
Technical field
The utility model relates to a kind of copper bar of two edges and grooves, belongs to electric power facility technical field.
Background technology
Copper bar is a kind of conducting heavy current product, in circuit, play a part carry electric current and be connected electric equipment, be applicable to the electro-engineerings such as high and low voltage electrical equipment, switch contact, controller switching equipment, bus duct, be also widely used in the super-large current electrolysis for production engineerings such as metal smelt, electrification plating, chemical industry caustic soda.
The long conductor that common copper bar cross section is rectangle, the copper bar of this structure can only meet general electric equipment products, has the occasion of special shape requirement can not be suitable for for some, can not meet the demand of electrical apparatus industry model change, the copper bar of square-section simultaneously, its installing space is limited; Existing copper bar junction structure is simple, and conductive area is little and there is no coating, therefore a poor electric conductivity; Copper bar is along with the increase of electric current, and temperature is more and more higher, and caloric value is increasing, and equipment and environment have been produced to bad impact.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency; a kind of copper bar of two edges and grooves is provided; it is high that this copper bar is applicable to the occasion of special shape requirement and conductivity and antiseptic property; and copper bar temperature while lowering the temperature to reduce large electric current by water flowing; make copper bar in large electric current in low-temperature condition; with protection equipment, improve the useful life of electric equipment.
The purpose of this utility model is achieved in that
A kind of copper bar of two edges and grooves, be characterized in: described copper bar comprises upper and lower, described upper and lower is rectangular slab, the width of bottom is little compared with top, described top is symmetrically arranged taking its vertical center line as symmetry axis, the right and left on top is inwardly provided with groove, the top and bottom of the outside of described groove are plane, the face of cylinder that inner edge is, the left part on top and right part are respectively arranged with the first through hole and the second through hole along its length, described the first through hole is inlet at the opening of a side on top, the second through hole is liquid outlet at the opening of top and the first through hole homonymy, the first through hole and the second through hole are tightly connected by bend pipe at the opening of another side on top.
The copper bar of a kind of two edges and grooves of the utility model, the outer surface of its upper and lower is all coated with layer of metal tin.
Compared with prior art, the beneficial effects of the utility model are:
1. the copper bar of the utility model two edges and grooves, the right and left on top is inwardly provided with groove, and groove effectively increases conductive area, thereby has improved the electric conductivity of copper bar, and groove has expanded workmen's installing space simultaneously, makes copper installation convenient; 2. the inner side of transverse slat and the surface in outside are all coated with layer of metal tin, because the chemical property of tin is very stable, and discord water, various acids and bases generation chemical reaction, therefore copper bar can be anticorrosive, again can gas defence; 3. the opening of two of upper side through holes is respectively inlet and liquid outlet; the opening of two through holes of opposite side is tightly connected by bend pipe; copper bar temperature while lowering the temperature to reduce large electric current by water flowing; make copper bar in large electric current in low-temperature condition; to obtain protection equipment and environment, normal good result of producing.

Embodiment
Referring to Fig. 1, the copper bar of the utility model two edges and grooves, comprise top 1 and bottom 2, described top 1 and bottom 2 are rectangular slab, the height on top 1 is 12mm, width is 37mm, the height of bottom 2 is 3mm, width is 30mm, the width of bottom 2 is little compared with top 1, described top 1 is symmetrically arranged taking its vertical center line as symmetry axis, the right and left on top 1 is inwardly provided with groove 3, groove 3 increases conductive area, thereby improve the electric conductivity of copper bar, groove 3 has expanded workmen's installing space simultaneously, make copper installation convenient, the top and bottom of the outside 3.1 of described groove 3 are plane, inner edge 3.2 be 90 ° of arc chord angles the face of cylinder, the degree of depth of groove 3 is 5.2mm, the top and bottom distance of the outside 3.1 of groove 3 is 5.2mm, the left part on top 1 and right part are respectively arranged with the first through hole 4 and the second through hole 5 along its length, the opening of the side of described the first through hole 4 on top 1 is inlet 6, the second through hole 5 is liquid outlet 7 with the opening of the first through hole 4 homonymies on top 1, the first through hole 4 and the second through hole 5 are tightly connected by bend pipe 8 at the opening of another side on top 1, water after filtering is entered to the first through hole 4 and discharges from the liquid outlet 7 of the second through hole 5 by bend pipe 8 from inlet 6, form a circulation circuit.
When this device is produced at maximum current, can make the temperature of copper bar drop to present 40 DEG C of left and right from 130 DEG C of left and right before.Reduce energy consumption, improved environment, protected the normal operation of equipment.
Embodiment mono-: the outer surface of top 1 and bottom 2 is all coated with layer of metal tin, this tin coating can effectively prevent that copper bar is in use oxidized, and can improve the contact-making surface that copper bar connects simultaneously, has strengthened the electric conductivity of copper bar, and can prevent by acid and alkali corrosion.
