8.5 million degrees. The electricity production of a 10,000 kilowatt hydroelectric plant is 10,000 kilowatt hours per hour, and the electricity production is 240,000 kilowatt hours 24 hours a day, 365 days a year. Excluding the dry season and maintenance period, the annual electricity production is 10,000 kilowatt hours per hour. at least 8.5 million kilowatt hours. A kilowatt is a unit of power equal to 1,000 watts. Initially, kilowatts were mainly used in electricity, but today there is a trend towards wider application.
| Solution: |
| Analysis of test questions: Solution: Loss of electrical energy on the transmission line Then the flow on the transmission line is? Then the output voltage of the step-up transformer is ? The voltage lost on the transmission line La step-down transformer input voltage Then
Comments: The key to solving this problem is knowing the voltage rise. The relationship between the output voltage, loss voltage and input voltage of the step-down transformer, as well as the relationship between the output power, output current and output voltage. . |
