The sudden fire explosion fault for a 35 kV shunt capacitor bank in operation is investigated and analyzed. The reason for the fault generation and development is analyzed and summarized by way of inspection of the equipment after the fault, fault record with combination of both structure and operation status of the faulty capacitor bank as well as simulation calculation. The measure to be taken to avoid the fault is pointed out. And the analysis result has important significance for the improving the operation reliability of the capacitor bank.
