Capacitor failure, how to eliminate

In daily life, about the axial capacitor common fault mainly has the following three, to master relevant knowledge and in a timely manner to eliminate the fault, can effectively increase the service life of the axial capacity.

the first case, the axial capacitance spark by overheating, fire wait for a phenomenon, should immediately cut off the power supply, quickly with sand or dry out the firearms to extinguish the flame, general this kind of problem is due to the voltage problem caused by the fault within the system. So once this happens we will strictly check fuse fuse must ensure that the specifications of the fuse to match, avoid repeated such accident.

the second case, the axial capacitance of the circuit breaker tripping, but fuse fuse didn't burn out. After this time should be first on the axial electric discharge in three minutes, and then carries on the circuit breaker, current sympathetic and axial capacitor appearance inspection, if found no obvious different often, the general is the failure or voltage fluctuation due to external causes, after further inspection, if the normal can be Fielding drills, to do a full power test conversely, if these method checks are not infested axial capacity, that is about to open to check each before check the correct reason should not be put into operation.

the third case, the axial capacity suddenly tripped, and fuse fuse was burned, it shall promptly report to the dispatcher on duty, after consultation of the disconnection of the breaker. And after the cut off power supply to check external structure, see if there was lightning traces or shell deformation, leakage after short circuit to wait for a phenomenon, with a shaking table test of the insulation resistance of the insulation, if haven't found the cause of the accident, will replace the fuse in the field, if change will continue to appear the phenomenon of fuse, will first quit the axial capacity, electricity check on other parts.
