The Chemical Engineering Theory section is launching a \"One Question per Day\" activity starting today, aimed at helping everyone reinforce their basic knowledge in chemical engineering. Subsequent series will include those on \"Principles of Chemical Engineering\", \"Mass Transfer and Separation\", \"Thermodynamics in Chemical Engineering\", and \"Chemical Process Engineering\". We hope you will give it your active support! Wishing everyone a happy Christmas! Answers to the questions in the \"One Question per Day\" activity can be viewed directly; the thread will be closed after 1 day ! To encourage everyone’s continued participation this year! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ Short answer question: What are the reasons for failures in the rectifier power supply of hydrogen stations? Answer: 1) Tripping is caused by a disruption in the cooling water supply or insufficient flow and pressure. 2) A sudden increase in current causes overcurrent, or a short circuit leads to tripping. 3) The fast fuse burns out, resulting in tripping. 4) Groove pressure, groove temperature, oxygen level, alkali solution circulation rate, level exceeding limits, and interlock actions causing the power supply to be disconnected in the rectifier cabinet
1) Tripping caused by a disruption in cooling water supply or insufficient flow and low pressure； 2) A sudden increase in current causes overcurrent, or a short circuit leads to tripping ； 3) The fast fuse burns out and triggers tripping ； 4) Groove pressure, groove temperature, oxygen level, alkali solution circulation rate, level exceeding limits, and interlock actions causing the power supply to be disconnected in the rectifier cabinet ；
