Abstract
The invention provides a big current square-shaped double-row heat dissipation static contact. The static contact comprises an outer insulating shell (1) and a copper conductor (2), and is characterized in that: the outer insulating shell (1) consists of an incoming line row cavity (3) and an outgoing line row cavity (4); the copper conductor (2) consists of a square-shaped incoming line row (5) connected with an incoming line and a square-shaped outgoing line row (6) connected with a moving contact (8), wherein an inclination angle between the square-shaped incoming line row (5) and the square-shaped outgoing line row (6) is nearly 90 degrees, the main body of the outgoing line row (6) is arranged in the incoming line row cavity (3), and the incoming line row (5), connected with the outgoing line row (6) in the inclination angle of nearly 90 degrees, is extended out of the incoming line row cavity (3); and one surface of the outgoing line row (6) is connected with a square-shaped line row (7) connected with the moving contact (8), the square-shaped line row (7) passes through the bottom wall of the incoming line row cavity (3) and is inserted in the outgoing line row cavity (4), and the other surface of the outgoing line row (6) is provided with cooling fins (9). The big current square-shaped double-row heat dissipation static contact has the advantages of convenient connection with the moving contact, big contact area, convenient manufacturing, good insulating effect, big contact force, small resistance and strong electric conducting ability.
Description
The present invention has applied for utility model patent simultaneously.
Technical field
The present invention relates to a kind of electric power and carry the accessory of distribution, especially a kind of fixed contact in withdraw-type switch cabinet, specifically a kind of big current square-shaped double-row heat dissipation static contact.
Background technology
As everyone knows, needs in service are to fixed contact moving contact moving with movable contact, the high-tension current on the transmission line in switch cubicle.
Present employed fixed contact mostly is cylindrical structural greatly, its maximum current is for being no more than 4000A, and the temperature effect that produces during equipment operation the equipment normal power supply, because cylindrical fixed contact diameter reaches 109, therefore contact area is restricted, and current value can't further improve, and only way has only the volume that enlarges fixed contact, and the real volume of switch cubicle that certainly will cause strengthens, and increases floor space and equipment investment.Present surge along with power load, the 4000A electric current consumption of most of sub-district power distribution station can not satisfy the productive life needs, and therefore designing fixed contact more jumbo, that volume is little, area of passage is big, resistance is little becomes one of key factor of present cell capacity-enlarging.
Summary of the invention
The objective of the invention is to be no more than 4000A at the electric current of present cylindrical fixed contact, can not satisfy the problem of power supply needs, a heat radiation difficult problem designs the big current square-shaped double-row heat dissipation static contact that a kind of resistance is little, conductive capability is strong when solving the high-current equipment operation.
Technical scheme of the present invention is:
A kind of big current square-shaped double-row heat dissipation static contact, comprise main body be square the external insulation housing 1 and the copper electric conductor 2 of structure, the described external insulation housing 1 of its feature is made up of square lead-in line row chamber 3 and square outlet row chamber 4, described copper electric conductor 2 is made up of with the square outlet row 6 who links to each other with moving contact 8 the square lead-in line row 5 that links to each other with inlet wire, square lead-in line row 5 and outlet row 6 are about 90 degree angles, outlet row 6 main body is arranged in lead-in line row chamber 3, with outlet row 6 be lead-in line row 5 that about an angle of 90 degrees links to each other from the lead-in line row chamber 3 extroversions stretch out outside the lead-in line row chamber 3; Be connected with the square line bank 7 that links to each other with moving contact 8 on outlet row 6 the one side, the diapire that square line bank 7 passes lead-in line row chamber 3 stretches in the outlet row chamber 4 so that link to each other with moving contact 8 in inserting outlet row chamber 4, and outlet is arranged 6 another side and is provided with fin 9.
The quantity of described square line bank 7 is 2.
Described fin 9 be shaped as zigzag, the peak of its sawtooth is positioned at outside the lead-in line row chamber 3.
Beneficial effect of the present invention:
The present invention has overcome the constraint of traditional concept, has adopted square structure double-row heat dissipation fixed contact first, and is not only reliable with contacting of moving contact, and contact area realizes the big current requirements of 6300A, and manufacturing process is simple, and it is good to have the exterior insulation security performance simultaneously.
The present invention has adopted heat radiating fin structure first on fixed contact, make to solve a heating difficult problem in the equipment operation, has guaranteed the equipment normal power supply.
