Wherein, described shell is divided into upper end cover and the bottom end cover that links together, and is filled with polyurethane and/or anti-seismic material and/or sound-absorbing material in the described upper and lower cover, thereby fills described coil, iron core and last fin and following fin and water pipe fixing.
Wherein, the two ends of described coil respectively are welded with a copper bar that is used for connection bus.
Wherein, described coil is a hollow form, is cast with epoxy resin layer at the coil skin that turns to annular.
Wherein, described coil is behind coil surface-coated insulating barrier, turns to annular again.This kind structure need not casting epoxy resin layer outside loop coil, and described material that is coated with insulating layer coating and thickness and the number of plies all can be regulated according to the requirement of coil insulation.
Wherein, the described fin of going up all has stainless water pipe head and waterpipe jointing with following fin on the inside and outside wall direction of coil; Waterpipe jointing water pipe perpendicular to side direction in the coil of the last fin of the coil inwall of coil straightway direction connects, and the corresponding position of corresponding following fin also water pipe connects.
The thickness of logarithm of iron core described in the utility model reactor and iron core air gap pad can be regulated according to the actual parameter of reactor; The described logarithm of going up fin and following fin can be regulated according to the actual parameter of reactor; The shape that is shaped as circle, ellipse or other arbitrarily suitable hollow form structures of described hollow form coil.
The beneficial effects of the utility model are:
1, kept a kind of number of turn relative fixed, adjust the advantage of the logarithm of iron core according to a reactor needs of different electric pressures and different parameters requirement, make when not changing the coil shape size, the overall dimension of every pair of iron core does not change yet, need not be its other design and installation size, manufacturing process is simple.
Though 2 coils and iron core have water pipe line design separately, but the design of the water route of iron core is very simple, also can realize modularization, overall dimension for fin also can change, only need get final product according to the logarithm that the logarithm of iron core is regulated fin, the fin that is placed between iron core directly dispels the heat to iron core, and radiating effect is very desirable; And several water routes to the fin between iron core are connected in parallel, and radiating effect is even; According to the coiling shape of winding, be connected in series perpendicular to the fin of winding straightway direction, symmetry is placed, and satisfies modular design concept.
3, the outlet terminal of coil is in the coil both sides, and electric capacity is little between end.Make that so again the coupling number of turn of coil and iron core is a fractional turns, strengthened and regulated the flexibility of inductance aspect the number of turn.
4, coil or need not the epoxy resin casting via epoxy resin casting or at coil surface-coated insulating barrier, the iron core fin of final and coil assembling be connected water pipe and clamping structure and cast via polyurethane again, further strengthen integrally-built stability.When last above bottom end cover is in package shape, can fill anti-seismic material and deadener, polyurethane has certain elasticity simultaneously, can reduce vibration and the reduction noise of reactor at run duration.
