Even more on the E's at the ruins
I'm sorry to say I dont get it.
a)the ruins were a building, most likely a farm house, yes?
b) These E's, were 'transformer laminations' (both Shades and the master concur) yes?
c) The E's are 'transformer laminations'... what does that mean?
d) And if so, and if the ruins are an ancient farmhouse why would they be there in their hundreds... in great piles like in this image...?
It might have been a light industrial unit, of course. Or the farmer rented out the barn. They wouldn't be hard to make, just being stampings out of a zinc sheet. An easy cottage industry in the olden days with a large hand press. (They might have just stamped them out as piece work for a transformer supplier).
ReplyDeleteTechy explanation-
Transformers have two coils wound around a former. Let us take an example of a Mamod model railway controller, the sort that had a red knob and a pop-up from when you overloaded it.
The mains went in one coil. This induced a voltage in the second coil in direct ratio to the number of turns.
Without a former, there is no voltage induced as it has to behave like an electromagnet. However, if it is a solid core eddy currents are induced as well, making it get overly hot and wasteful. The laminations dramatically reduce the eddy currents provided that the E's are coated to insulate them. The bit that turns the E into an 8 has to complete the circuit for it to work properly and it is arranged so that the windings can be slid in without having to lace them through holes.
I appreciate and get the first paragraph, but the 'techy' explanation is beyond my understanding, me being just a cook, a lowly lowly cook...master can you simply Shades's explanation even further for me?
ReplyDeleteThe 'e's were probably out of old TV sets. We used to find thousands of them behind Riverside Rentals TV shop in Forest Hall where they fitted new transformers to the cathode ray tubes. Great for chucking, stuck in concrete too.
