Description
Technical field
The present invention relates to the self cooling smoothing reactor of a kind of dry-type hollow, be widely used in the direct current major loop.
Background technology
Traditional self cooling smoothing reactor of dry-type hollow adopts copper cash or aluminum steel coiling at present, and the general class of insulation is the B level, and coil has only axial ducts, does not have the width of cloth to the air channel, perhaps has only the width of cloth not have axial ducts to the air channel.Reactor winding heat radiation difficulty, current density Δ=1.6a/mm
2Below, the self cooling smoothing reactor of these old dry-type hollows is many with material, and weight is big, and volume is big, and the cost height is not so reach optimum efficiency in electrical operation.
Summary of the invention
The purpose of this invention is to provide a kind of copper strips around the self cooling smoothing reactor of H grade insulation dry-type hollow, this reactor has overcome the technical deficiency of the self cooling smoothing reactor of traditional dry-type hollow, has class of insulation height, perfect heat-dissipating, temperature rise is low, volume is little, in light weight, advantage that overload capacity is strong.
For achieving the above object, the present invention is achieved through the following technical solutions:
Copper strips around the self cooling smoothing reactor of H grade insulation dry-type hollow, comprise coil, insulating press boards, pull bar, it is characterized in that: coil adopts single cake formula, layer is provided with interior insulating stay in coil, the outside lead that twines of interior insulating stay is a bare copper strip, is provided with insulation air channel bar between every circle coil, is provided with cross-over block between adjacent cake, insulating press boards clamped with pull bar about coil adopted, and was provided with insulating stay in the outside of coil; Described inside and outside insulating stay, insulation air channel bar, cross-over block all adopt the H class F insulating material F.
Described bare copper strip is every circle with 3 bare copper strip parallel connections, adjacent two cakes butt joint, 3 bare copper strips of every cake coil by circumference respectively 120 ° draw joint.
Described cross-over block is the high frequency glass fibre block.
Bar inside, described insulation air channel is provided with the ventilation groove.
Described pull bar adopts the non-magnetic rustproof reinforcing pull rod.
Described cross-over block two ends are provided with groove, match with inside and outside insulating stay.
The present invention's beneficial effect compared with prior art is:
1) this product adopts the H class F insulating material F, and reactor winding can bear temperature rise 125T, and temperature rise can reach 145T during overload, 180 ℃ of maximum temperatures, the H class F insulating material F is all not combustion-supporting, and burning capacity is low, in 800 ℃ of burnings of high temperature, not having has toxic smoke, good springiness, be difficult for aging, service life is high.
2) the reactor winding load current is big, need the heavy in section to amass lead, select bare copper strip very suitable, particularly reactor winding is to adopt single cake formula, every circle is with 3 bare copper strip parallel connections, 3 bare copper strips of the every cake of coil respectively 120 ° lift one's head adjacent two cakes butt joint, thereby realize that many copper strips parallel connections do not replace, thereby significantly reduce the supplementary load loss of coil.
3) the every circle of reactor winding is provided with H class F insulation air channel bar, is provided with smooth ventilation groove in the bar of air channel, and air flows is unimpeded; Be provided with the high frequency glass fibre block between the coil cake, temperature influence is not indeformable 800 ℃ of high temperature, does not ftracture, and does not damage, and resistance to compression, anti-seismic performance are good, has improved reactor winding heat dispersion and insulation thermal endurance class greatly.
4) reactor winding adopts the high heat dispersion coil, axial ducts and the width of cloth have been formed to the air channel by the high frequency glass fibre block between the every circle H of coil class F insulation air channel bar and coil cake, the coil dead angle of not dispelling the heat, heat distribution is even, avoid reactor winding local temperature rise too high, cause that reactor winding burns out.
5) reactor winding, current in wire density can reach 2.5a/mm
2More than.General drum type brake, continous way, helical winding current density are at 1.6a/mm
2Below, thereby coil of the present invention can be saved a large amount of raw material.
6) coil adopts insulating press boards nonmagnetic steel pull bar clamping up and down, and interior outer stay arranged, by the vacuum pressed dipping lacquer, make coil become as a whole, guarantee that the reactor winding lead is when overload, and 25 times of rated current short circuits, the electric power that is produced can not make hollow smoothing reactor lead be subjected to displacement and damage.
In sum, copper strips around the self cooling smoothing reactor of H grade insulation dry-type hollow simple and reasonable, good electric property, the mechanical strength height, perfect heat-dissipating, coil temperature rise is low, volume is little, and is in light weight, low noise is the self cooling smoothing reactor of dry-type hollow of new generation.
