Description
Technical field
The utility model relates to a kind of filter condenser, particularly a kind of self diagnosis filter condenser.
Background technology
Progress along with science and technology; power system uses the equipment such as rectification, frequency conversion, heavy-duty motor and electricity-saving lamp inferior in large quantities; the thing followed is that the pollution of electrical network is increasingly severe; 5,7,11, the 13 inferior higher hamonic waves that capacitor impact is huge are exaggerated again by compensating electricity container; make the serious overcurrent of capacitor; heavy then at once damage capacitor; light then make capacitor be greatly shortened service life; and existing frequently-used filter capacitor; only protected fuse on filter circuit; once capacitor is damaged, investigation difficulty.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of structure optimization, fault self-checking, the convenient filter condenser of maintenance.
For solving above-mentioned technical problem, the utility model realizes as follows: a kind of self diagnosis filter condenser of design, it is made up of capacitor, capacitor protection fuse, normally closed relay, filter circuit and alarm sounds unit；Capacitor protection fuse electrically connects with capacitor pin composition；Normally closed relay electrically connects with capacitor protection fuse, filter circuit composition；Normally closed relay electrically connects with alarm sounds unit composition.
Further, the control circuit of described normally closed relay is connected on capacitor protection fuse, filter circuit.
Further, the switching circuit in series of described normally closed relay is on alarm sounds unit.
Further, described normally closed relay switches off when energising, switch Guan Bi during power-off, it is achieved fault self-diagnosis.
Good effect of the present utility model: a kind of self diagnosis filter condenser, quickly positions fault, simplifies repair process, shortening troubleshooting time, substantially increase the overhaul efficiency of capacitor.
