10kV Dry-Type Air Core Reactorr,Current Limiting Reactors
1. Overview of 10kV Dry-Type Air Core Reactorr,Current
Limiting Reactors
Compared with traditional oil immersion iron core reactor,dry-type
air core reactors have advantages of light weight,good
linearity,stable reactance,small loss ,low noise ,etc.The epoxy is
adopted for envelopment,with high mechanical strength and
super-high short-time current resistance ability .It is simple in
structure and compact without oil.The star bracket and lead wire
are welded by adopting the argon arc welding to greatly improve
reliabiility of operation;Coverd with ultraviolet resistant paint
on surface,it can be used for indoor and outdoor longtime
running.Whereas the above-mentioned reason,dry-type air core
reactors gradually supersede traditional oil immersion iron core
reactors.
2. Main features of 10kV Dry-Type Air Core Reactorr,Current Limiting Reactors
- The reactor is enclosed by epoxy resin impregnated long glass
fiber.The reactor is composed of several enclosures of coils.
- The coil is insulated by polyester film ,which has good capability
of insulation.
- The reactor is painted with resisit aging ,ultraviolet-proof
insulation coatings,and has fine performance operating outdoors.
- Between enclosure of coils,supports made of polyester glass fiber
are used for axial heat radiator, this construction has abetter
property of heat radiation.
- When making calculation of temperature rise,we consider of the
highest temperature of the hottest spot and keep a preferable
margin.it can guarantee the long term safe operation of reactors.
- The whole reactors is integrated in high temperature heating
room,the leading-out ends of each winding layer are welded to upper
and lower spider arms ,all these make the reactors have many
advantages,such as high strength,low noise,better ability against
short-circuit.
- The reactor adopts small round section aluminum wires(Φ1.9~Φ4.5)as coil condutor ,thus effectively reduce vortex losses of
coils under harmonic waves.
- The structure is simple and compact.The reactor can operate
outdoors with convenient maintenance.
