(1)When the capacitor explodes and catches fire, disconnect the power immediately and put out the fire with sand and dry fire extinguisher.
(2)Film capacitor manufacturer when the insurance of the capacitor is fused, it should report to the dispatch, and pull the circuit breaker of the capacitor after getting the consent. Cut off the power supply to discharge it, first external inspection, such as the external casing has no flashing traces, whether the shell is deformed, oil leakage and grounding device has no short circuit phenomenon, etc., and shake the insulation resistance value between the pole and pole to ground, check whether the capacitor group wiring is complete and solid, whether there is a lack of phase phenomenon, if no fault phenomenon is found, can be put in after changing the insurance. If the insurance is still fused after the power supply, the faulty capacitor should be withdrawn and the rest of the power supply should be resumed. If the insurance fuses at the same time, the circuit breaker also tripped, this time can not be strong to send. It should be put in after the above-mentioned inspection is finished and the insurance is changed.
(3)The circuit breaker of the capacitor trips, and the branch insurance is not broken, should first discharge the capacitor for three minutes, and then check the circuit breaker current transformer power cable and the outside of the capacitor. If no abnormality is found, it may be due to external fault bus voltage fluctuation. After inspection, you can try to cast; otherwise, should further the protection ** energized test. Through the above inspection and test, if the cause is still not found, it is necessary to act according to the system and test the capacitor gradually. No test throw before the cause is identified.
