The inductive reactance damage that cable generates, stable structure is durable, and maintenance is few.
The consumable electrode vacuum furnace power bus of the utility model switchs, in design, it is known that design condition:
Due to being melting under vacuum, consumable electrode vacuum furnace is low-voltage dc power supply, maximum current 20000A, due to
Connecting copper block is extremely short, therefore by practice and theoretical calculation, in the case where there is water cooling, current-carrying capacity is up to 24~25A/mm2.If
Meter process is as follows:
Water conservancy diversion area between two bus gripping blocks 9 (conducting block) of power bus switch is 800mm2, briquetting length
254mm, the contact width needed are at least 3.14mm, and conducting area and good is contacted to guarantee bus gripping block with burner copper bar
Good contact situation uses the shape of inverted trapezoidal in the pressure head of bus gripping block 9, seal face width 3.2mm leads in order to avoid beating arc
It crosses material and compresses plastic deformation, realize the good contact of conducting area and conducting surface.
It is clamping cylinder two of 200mm that driving clamping device, which selects cylinder diameter, left and right sides each one, calculates each clamping gas
(compressed air pressure is set in 6Kg/cm to chucking power caused by cylinder2), according to cylinder thrust computing formula:
F=P*A*9.8
F is that cylinder is contributed (N), and A is sectional area (cm2), P is the pressure (kg/cm used2)
F=6* (0.785*20*20) * 9.8=18463N
The power that two clamping cylinders are exported is 2*18463=36926N
Elastic modulus E is 109Gpa.
(unit is dynes/cm to E=o '/ε2)
E is young's modulus in formula, and o ' is stress, and ε is strain.
σ=F/A=36926/ (0.254*2*0.003)=24229659Pa=0.0242Gpa
ε=o '/E=0.0242/109=0.000222=0.0222% < 0.2%
Deformation coefficient is much smaller than the yield limit of 0.2% residual deformation of copper product, so being safe and reliable.
8 built-in water-cooling of bus gripping block changes away the thermal energy generated when melting.
In conclusion the consumable electrode vacuum furnace power bus of the utility model switchs, realize that gripping block is steady by guide rod
Operation is clamped, so that more compact structure, and the thermal energy generated when melting can be changed away in time.
