20151120 Daily Question: The rewards are as follows: 1-3 points for participation, 5 points for a correct answer, and 8-10 points for a correct answer accompanied by an analysis. The equipment power of a welding machine refers to the active power when the rated power is converted to a load duty cycle of (). A. 15% B. 25% C. 50% D. 100% The answer is D
The equipment power of a welding machine refers to the active power obtained by converting the rated power to a load duty cycle of (D). Calculation of welding machine power: The calculation of welding machine power refers to the conversion of the rated power into the active power at a load duty cycle of 100%. (4-2) Pe = PN * √(Jcn/JC100) = √(Jcn) * SN * C0Sφ. Here, Pe represents the power of the welding machine when converted to JC100 units (in kW) ； PN — Rated power of the welding machine as indicated on its nameplate before conversion (kW) ； SN — Rated apparent power (kVA) on the welder’s nameplate before conversion ； C0Sφ —— Power factor of the welding machine
Answer: D (100%) Section 2, Chapter 1, Part 1, Article 3 of the third edition of the \"Manual for Industrial and Civil Power Distribution Design\" states that the equipment power of a welding machine refers to the active power obtained by converting the rated power to a load duty cycle of ε equal to 100%. Pe = Sr * COSΦ * √ε￣ Where Sr is the rated capacity of the welding machine in KVA; COSΦ is the rated power factor (please refer to the values in Table 1-2, Section 3, Chapter 1 of the third edition of the \"Handbook on Industrial and Civil Power Distribution Design\"); ε is the load duty cycle
I’m very sorry; I didn’t check carefully while typing and made a mistake. Now, I will correct the mistakes. Sr: The rated capacity of the welding machine, in KVA (*): Indicates multiplication
. . . . . Still wrong. :'(:L:dizzy: Change “large capacity” to “rated capacity”, change “large capacity” to “rated capacity”, change “large capacity” to “rated capacity”. Say the wrong thing three times.
Don’t emphasize the problem too much; it’s not a mistake – it’s probably just a typo on your part. Hehe, humility helps one to improve; let’s all work together.
