Abstract: The distribution control cabinet of a power plant has been operation for a long time, it been seriously burnt by the short circuit fault during the operation of the equipment. According to the faults and existing problems of the equipment, the possible problems are studied first from the defects in the design of the distribution board, and the working environment conditions around the equipment then the daily management of the equipment, the cause of the short circuit fault of the electrical equipment is finally determined.Take into account the aspects of technology, environment and management, and combined the site operation condition of controlled equipment, the upgrading and improvement of the original thermal power distribution board is realized, and the safety, reliabiliy and stability of the distribution equipment are further improved.
Key words: thermal distribution panel; relay; electrical short circuit; electrical arrangement
