Description
Technical field
The present invention relates to a kind of dry type hollow current-limiting reactor.
Background technology
Dry type hollow current-limiting reactor has only coil, there is not iron core, magnetic circuit is that the non-magnetizer magnetic resistance is very big, inductance value is very little, do not have saturated phenomenon, inductance value is a constant, because the good electrical characteristic of dry type hollow current-limiting reactor, being widely used in power engineering and each field of modern electrician, is the indispensable visual plant of electrical engineering.
Traditional dry type hollow current-limiting reactor has three kinds of patterns.One, be with concrete with the reactor winding that winds, water and dress up firm integral body and be referred to as cement reactor, this cement current limiting reactor volume is big, weight greatly, too heavy.Its two, be the wrapped reactor that is referred to as with modified line footpath (little line footpath) aluminum steel coiling, the easy oxidation of this current limiting reactor aluminum steel, bad mechanical strength, the life-span is low.Its three, with pressing plate and pull bar the reactor winding tension that winds is referred to as the clamping reactor, this current limiting reactor, humidity resistance is poor, supplementary load loss are big.More than three kinds of reactors in electric power system, move and all do not reach optimum efficiency.
Summary of the invention
For solving the deficiencies in the prior art, the invention provides a kind of 35 kv 3-phase dry type hollow current-limiting reactors, this reactor adopts brand new, and its loss is little, the mechanical strength height, limiting short-circuit current is big, insulation against ground level height, protective capacities is strong, and is easy to use.
For achieving the above object, the present invention adopts following technical scheme:
35 kv 3-phase dry type hollow current-limiting reactors, comprise coil, insulating cylinder, supporting plate up and down, it is characterized in that: the copper stranded conductor that the coil of reactor adopts many fine copper wires to form is wound on the insulating cylinder, and the copper stranded conductor outside is surrounded by insulating barrier, and every layer line circle outside all scribbles epoxy curing agent; Be provided with F class F insulation cold-drawn air channel bar between every layer line circle, its upper and lower end parts is provided with the end insulation, and the end insulation thickness is identical with diameter of wire; Wear bar by insulation and pass air channel bar and end insulation, air channel bar riveting is being held on insulation and the supporting plate.
Insulating cylinder adopts moulding epoxy fibreglass cloth tube, and its monolateral thickness is δ=3mm.
The insulating barrier of copper stranded conductor outside adopts polyvinyl chloride, and its monolateral thickness is δ=3mm.
The air channel bar is provided with ventilation ducts.
Hot-forming expoxy glass silk fabric board is adopted in the end insulation.
Supporting plate adopts the nonmagnetic steel supporting plate.
The outer netted glass fiber of multilayer that adopts of reactor winding does not have the binding of latitude band.
Reactor winding top is provided with flashing board.
The reactor winding bottom is supported with a plurality of porcelain insulators.
The invention has the beneficial effects as follows:
1) adopts the conductor of many copper stranded conductors as coil, its objective is and prevent that air core reactor operation under big electric current high voltage from producing highfield, make the lead generation kelvin effect of coil, thereby reduce the supplementary load loss of hollow current-limiting reactor, reach energy-conservation purpose, the copper stranded conductor dielectric voltage withstand is more than 3000 volts/layers.
2) coil of reactor is directly on the epoxy fibreglass cloth tube of moulding, every layer line circle is provided with the smooth air channel of F insulation cold-drawn bar, make coil air smoothness, the heat radiation of lead two sides, there is not dead corner, improve the heat-sinking capability of reactor winding greatly, make reactor current in wire density reach Δ=2.5a/mm
2More than, coil temperature rise is no more than 65 ℃.
3) reactor winding, every layer of end is provided with the end insulation of hot-forming expoxy glass silk fabric board, and the end insulation thickness is identical with diameter of wire, and density reaches 50mm.In winding process, all use insulation to wear the bar riveting in the end insulation especially, every layer conductor all firmly is pressed under the bar of air channel, add every layer line circle lead and all be coated with epoxy curing agent, every layer conductor is all firmly sticked together bar both sides, air channel.Thereby improve hollow current-limiting reactor Short Circuit withstand current capacity greatly, even reactor winding short circuit under 25 times of nominal current conditions, the electric power that short circuit current produces can not make the hollow current-limiting reactor winding wire be subjected to displacement yet, and causes damage.
4) the reactor skin does not have the latitude band around the netted glass fiber of multilayer, and the lead of coil is tied up effectively, and the current limiting reactor coil is by vacuumize, the vacuum pressed dipping lacquer makes the reactor lead, and insulating part all firmly sticks together, and the coil outer surface scribbles anti-ultraviolet, protection against the tide, the curing agent of anti-embrittlement.
5) the reactor winding bottom is being supported with a plurality of porcelain insulators, and the porcelain insulator bending stress reaches 10,000 newton.Reactor winding and porcelain insulator, flashing board reasonably connect together, thereby make reactor become a firmly integral body, improve the insulation against ground level and the stability of current limiting reactor greatly.
In sum, the present invention has that simple and reasonable, Short Circuit withstand current capacity is strong, good electric property, volume is little, in light weight, loss is little, low noise advantage.
