Now we apply these formulations on an example. Vn DETERMINATION (see page 4) HOT SPOT TEMPERATURE CALCULATION (see page 4) C = 6000 F DC voltage = 1850 V f = 300 Hz Irms = 208 A According to data: Vr = 52 V peak-to-peak Vw = 1850 + 52/2 = 1876 V Example: Cn = 6120 F (page 13) Vn = 2000 V H = 640mm Using the previous example: Cn = 6120 F Vn = 2000 V Vw = 1876 V f = 300 Hz Irms = 208 A The cooling air temperature: amb = 50C From the tables find the following constants: (find in the table) S = 70.5 dm2 Rs = 0.66 m The hot spot temperature in this example is therefore: HS = 56.8C 2200 2100 2000 1900 VN VW Vr 1800 1700 Vdc 1600 f = 300 Hz 1500 MTBF CALCULATION (see page 5) For a train application (4) in favorable conditions (1) in accordance to IEC 61071 (2) Vw = 0.9 Vn (400,000 h of expected lifetime) HS = 56.8C = Bx2x4x1 = 9x10-9 failures/hour MTBF = 111 x 106 hours 16 CALORIFIC VALUE L W H N = = = = (see page 8) 340 (13.386) 165 (6.496) 640 (25.197) 2 millimeters (inches) CV#1506MJ P/N TO ORDER DKTFM2K006127 TRAFIM Products Standard LIFETIME EXPECTANCY DESIGN V W/V N 1.1 1.05 CURVE 1 Vw/Vn vs Hot spot temperature 1 0.95 (Lifetime expectancy : 100,000 hours) 0.9 0.85 0.8 0 10 20 30 40 50 60 70 80 (C) V W/V N The highest Vw/Vn ratio (= max) for a lifetime of 100,000 hours can be deduced from Curve 1. max = Vwmax/Vn = 1.040 so VWmax = 2080 V (= 1.040 x 2000) (for HS = 56.8C and 100,000 hours) 1.6 1.5 1.4 ( hot spot temperature of 70C) 1.3 CURVE 2 Vw/Vn vs Lifetime expectancy 1.2 ( hot spot temperature of 56.4C) 1.1 max 1 0.9 0.8 1 10 100 1,000 10,000 100,000 1,000,000 Lifetime expectancy (hours) According to Curve 2, theoretical lifetime expectancy at Vw = 1876 V and HS = 56.8C can be determined. This gives a lifetime of 400,000 hours for this capacitor under working conditions. This value is explained by the choice of Vn >> Vw. 17 TRAFIM Products Custom APPLICATIONS DC voltage filtering for: DC link Resonant filtering Active correction (FACTS, UPFC, DVR...)

22 TRAFIM Products Custom DESIGN EXAMPLE Previously, we gave all the basic information to design a capacitor. Now we apply these formulations on an example.

They are shown on page 25. LOW INDUCTANCE OPTION This inductance can be reduced by approximately 75nH by using 4 terminals instead of 2 (see mechanical design chapter). If this solution does not reduce the inductance sufficiently, we suggest taking the low inductance option (down to 40nH). Please note that the low inductance option will increase width as well as weight: W + 10mm Weight +10% (approximately) Terminals 4 terminals will be used instead of 2. TERMINALS AND CONNECTIONS millimeters (inches) Epoxide terminals, mechanically assembled by O-ring. 9 solutions of terminals are offered, the most standard is type 2. On specific requirements we can propose other solutions depending on the waited function. 1 2 Body Creepage distance Air distance 52 (2.047) 78 (3.071) 30 (1.181) 50 (1.969) 2 waves 4 waves M12 (0.472) 3 M12 (0.472) 30 (1.181) 1 (0.039) 23 (0.906) 1 (0.039) 40 (1.575) 1 (0.039) 23 (0.906) 1 (0.039) 23 (0.906) 1 (0.039) o60 (2.362) o60 (2.362) 4 o60 (2.362) 5 6 33 (1.299) 1 (0.039) M16 (0.630) 30 (1.181) 1 (0.039) o13 (0.512) 0.5 (0.020) 32 (1.260) 1 (0.039) 40 (1.575) 1 (0.039) 23 (0.906) 1 (0.039) o60 (2.362) o60 (2.362) 7 8 12 (0.472) 1 (0.039) o13 (0.512) 0.5 (0.020) 32 (1.260) 1 (0.039) 40 (1.575) 1 (0.039) o10.2 (0.402) -0 +0.5 (0.020) M16 (0.630) 30 (1.181) 1 (0.039) o10.2 (0.402) -0 +0.5 (0.020) o60 (2.362) 12 (0.472) 1 (0.039) 9 41 (1.614) 1 (0.039) M8 (0.315) 41 (1.614) 1 (0.039) 40 (1.575) 1 (0.039) 23 (0.906) 1 (0.039) o60 (2.362) 24 o60 (2.362) 17.0 (0.669) 23 (0.906) 1 (0.039) o60 (2.362) TRAFIM Products Custom MECHANICAL DESIGN Low Inductance Option 80 80 80 (3.150) (3.150) (3.150) 50 (1.969) 4 Terminals Option M8 (0.315) x 25 (0.984) 80 80 80 (3.150) (3.150) (3.150) 50 (1.969) Standard Design M8 (0.315) x 25 (0.984) 80 (3.150) 180 (7.087) 114 (4.488) M8 (0.315) x 25 (0.984) H H H 340 (13.39) 30 (1.181) W + 10 (0.394) 340 (13.39) 340 (13.39) 20 (0.787) 30 (1.181) W W 30 (1.181) 30 (1.181) 20 (0.787) Mounting Brackets (M) (suggested) Lower Brackets Removed for H < 500 mm Bolts M (B) (possible) Bed Plate (P) (possible) 50 (1.969) 80 (3.150) H-100 (3.937) H-210 (8.268) 13 (0.512) 90 (3.543) 30 (1.181) 18 (0.709) 22 (0.866) W + 27 (1.063) 100 (3.937) 10 (0.394) M8 (0.315) 366 (14.41) 385 (15.16) 430 (16.93) 25 TRAFIM Products Custom MECHANICAL DESIGN SMALL BASE TRAFIMS 166 x 152 (6.535 x 5.984) These capacitors can only be equipped with two terminals and therefore are not available in low inductance four terminals version.
