530kW motor checks? !!

Former Community Member over 4 years ago

Hello to all, and I do hope that people can advise me on this?

Firstly: what checks can I best do for a possible purchase of a single ABB - AMB 630 LC16 ABA C 530kW pump unit, which is unable to be properly tested (powered up) as the plant it was operating in has been decommissioned, and is currently being scrapped.

The unit appears to be mostly self contained, with a separate 'powercap' capacitor cabinet.

There are 8 in total, in various conditions and all look like this:

Secondly: No switching gear is 'included', however I could always ask the company (who's pulling the site apart) if it's possible to obtain the original starter systems maybe???

But would this be a good idea, considering again it's in an unknown condition.

From the 8 available, I've selected 2 that appear to be the most suitable for hopefully reusing again (not bashed about, leaking oil etc) and thus generally look ok, so possibly from that can choose the final one.... but it would be great to know how best to maybe pick the best from any testing that could be done where they stand now, without any power.

Obviously with big industrial machine as this, it's not your average consumer second-hand electrical goods....

....that one just plugs in, and then hopes it works when power is applied!

(Thanks in advance to any replies)

Those lifting eyes will have a lot of margin in terms of ultimate failure loading, but I agree lifting it as an unbalanced load is not at all wise, really it needs to be done in the way that removal is the reverse of assembly. And that is before worrying about transport locks and so on.

The 11kV lines wont be that thick - you are only looking at about 20A or so per phase, so more insulation than copper - the copper core could be a few mm2, with half an inch of insulation - that is the joy of HV.

Glad you got good intel from the makers, pity the dismantlers do not have this rigour of approach.

Yes I noticed the variation in current on the tigertek rig - I presume that is why the motor is there to be fixed, it may mean there is a winding or an alignment fault, or the calibration on the rig is bit off, or less sinsister, perhaps there are unequal resitances in the hook-up wiring. (though the secondary currents will be pro-rata less, the odd ohm astray could be problematic.)
