Magnetic Clearances Around Reactor Banks
Magnetic Clearances Around Reactor Banks
(OP)
Question?
Manufactures of air core reactors show magnetic clearance boundry lines for their reactors. Some show a boundry for metal not forming a continous loop and one for those forming continous loops. Some also show the boundry lines as they extend underground. I have seen designs where the reactors are situated within each others magnetic boundry while others are not within the boundry lines.
My question is how do you handle these requirement?

RE: Magnetic Clearances Around Reactor Banks
If the reactors are air-core, the mutual coupling between the reactors shouldn't cause any major heating effect, but it might have some impact on the reactance, although I wouldn't expect it to be major. But I'm basically guessing about that.

these are air core reactors and they are operating at 17kV and have a fault duty of 65KA.

On the reactor drawing, there should be a dimension of the minim distance between center-lines of adjacent reactors. It is very important to maintain this clearance. Heating can be a concetn, but more importantly the mechanical forces that the reactor sees during a fault is affected by this clearance.
Certainly for a reactor with a rating of 65 kA, this clearance is critical. The reactor and the insulator configuration has been designed with this clearance in mind. Putting the reactors too close together could cause the reactors to fail mechanically and electrically during a fault (which of course is when you need them the most!).
