22kV 200A Dry-Type Air Core Reactor,Current Limiting Reactors
1. Overview of 22kV 200A Dry-Type Air Core Reactor,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 22kV 200A Dry-Type Air Core Reactor,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.
- Dry-type semi-iron core reactor puts the iron core column in the
hollow core of the hollow reactor, without enclosing the entire
coil, and the iron core consumption is small;
- The core column is made of high-quality low-loss imported
cold-rolled silicon steel sheet, which has high magnetic
permeability, small coil diameter, low loss and low energy
consumption;
- The core column adopts integral vacuum epoxy casting molding, which
is dense and strong as a whole, with high mechanical strength and
low noise. The reactor can be directly used outdoors after being
treated with special protective measures, without being restricted
by any environmental conditions;
