The member that the first runs a guarder should record the moving case of dc screen everyday, voltage, electric current is worth, discover the problem is handled in time;

The 2nd is safeguarded daily

1, it is normal to check each signal lamp to work;

2, carry storage battery exterior cleanness;

3, accumulator group moves state examination:

(The fluid face of 1) batteries should is close to on fluid cover line, if  discovers electro-hydraulic on the low side should fill in time add distilled water, if discover accumulator leakage fluid to answer instantly fish reason gives processing, lest affect the insulation of whole group accumulator;

(2) runs temperature rise: Accumulator is not calorific when float fills position, if discover individual batteries has calorific phenomenon to should examine a reason instantly, handle in time, if discover whole group batteries is calorific, the moving status that  should check batteries above all (be filled by force or discharge all has certain temperature rise) ,  whether float fills electric current too big or batteries group produces the phenomenon such as exterior small short circuit, discover the problem should be handled in time. Accumulator is common breakdown consults please accumulator part;

(3) checks the join of accumulator group to nod, the contact is close, have without oxidation, besmear with petrolatum;

Screen of the 3rd dc is common the processing technique of breakdown:

1, commutator of silicon closing gate or control silicon commutator break phone:

(1) communication breaks phone into line power source, will produce commutator of silicon closing gate, control silicon commutator, charge power source is given out at the same time miss telegraphic mark, after waiting for power source to return to normal, eliminate naturally;

(Output of dc of 2) silicon commutator carries fast frit fusing, or dc output carries air switch to take off buckle, send single signal, change the fast frit that is the same as norms or in the sky add up to gas switch, breakdown is eliminated; Origin: HTtp://tede.cn

(Alternating current source is short of 3) , dc outputs voltage to be able to achieve the 60%-70% of rating only, with avometer input of the commutator that measure silicon carries three-phase voltage can, fish breaks photograph reason  , after processing, can return to normal;

2, charge the processing that power source breaks phone:

(Alternating current source breaks 1) report;

(2) controls silicon commutate to break phone,  charges the ability when it is normal that power source can work in control silicon commutator only works, if control silicon commutator to break report or breakdown, charge power source cuts off accumulator group automatically to be filled by float turn to work for discharge condition, wait for control silicon commutate to return to normal, can start charge power source;
