Soft start maintenance master wechat
ID: ctcr123 simple work
13908182700 engaged in the research and development of motor soft
start control algorithm after-sales maintenance for nearly ten
years, is committed to the soft start control board drive board
maintenance of imported brands for more than 6 years, accumulated
countless maintenance cases and experience, basically can do not
limit the fault, not to change the board maintenance, there is a
fault in this can
contact. You can also
send emails to consult and
exchange. 13908182700@163.com
In the second semester of grade six, the child was a
little busy, and there was almost no time to record
maintenance. A customer in Shijiazhuang, Hebei
Province sent two Siemens soft start, one corner phase fault, one
can not start the thyristor temperature is too high.
Are used on the compressor of the gas station, the fault is
more difficult to get.
Check as follows
Brand: Siemens
Model number: 3RW4445-6BC44
Current :313A
Power: 160KW
Voltage: 400v
Fault phenomenon: start the alarm phase Angle control
fault, can not start the motor.
Maintenance idea: The main host SCR is basically normal,
the drive board is normal, and most of the faults can be repaired
when the control board moves to part.
This fault has been encountered several times before,
according to previous experience to repair not done, boot no longer
alarm, repeated automatic restart, do not know where there is a
problem. Don't be too embarrassed
There are two cases when the phase Angle control error
occurs in the 3RW44 soft starter:
1. Possible causes of failure when the motor does not
start:
a. Motor connection is incorrect;
b. The internal loop is incorrectly configured.
c. The ground fault occurs.
Solution: Check the cable connection.
2. Possible causes of motor startup failure:
a. The starting voltage is too high.
b. Trip pulse setting error.
Solution: Check parameter Settings and extend buffer time
appropriately.
A week later, the problem was finally solved and started
normally. It was sent to the site in Shijiazhuang and started
normally, and there was no alarm. The fault was repaired
successfully.
