The static contact is not only convenient in connection with the moving contact and large in contact area, but also convenient for manufacturing, and has the advantages of good insulation effect, large contact force, small resistance and strong electric conductivity.
Description
The utility model has been applied for patent of invention simultaneously.
Technical field
The utility model relates to the accessory that a kind of electric power is carried 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 purpose of this utility model is that the electric current at present cylindrical fixed contact is no more than 4000A, 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.
The technical solution of the utility model 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.
The beneficial effects of the utility model:
The utility model has overcome the constraint of traditional concept, adopted square structure double-row heat dissipation fixed contact first, not only reliable with contacting of moving contact, 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 utility model 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.
