Dc generatrix volmeter does not have voltage, “ accumulator has processing of apparent breakdown “ :
1) discover dc generatrix volmeter not to have voltage, dc disappears. After via checking discovery accumulator has bigger trouble, ying Xun fast to attemper reach unripe ability division to report accumulator breakdown case.
2) exit silicon commutate.
3) fill what shed screen to go up continuously switch knife to swing to bus side up.
A) starts silicon commutate.
B) pulls open accumulator and knife of brake of join of straight on-line drifting a mother.
C) gets off accumulator enters on-line of dc screen mother, negative pole is safe.
D) adjusts the potentiometer that fills electric screen to go up till bus voltage is 220V.
E) exits the coincide brake pressing plate of all switch.
F) pulls open knives of all brake of power source closing gate on dc screen.
G) processing is backward attemper report of the division that reach ability already renewed dc power supply, make the detailed record of good processing
H) awaits substation to be overhauled to accumulator.
