The present invention is a reactor design method which is realized by using a computer 80 in order to determine the parameters which are required for forming an air core reactor 70 comprising coils 72 which are disposed telescopically and which are connected in a parallel manner with respect to each other and accordingly where data is entered through a user interface 81, and where predetermined calculations are made by a processor 83 by means of software, provided in the memory of. This paper proposed optimal design of iron core shunt reactors with discretely distributed air gaps that can suppress overvoltages of high voltage transmission line in various situations, such as. They dont saturate, are virtually maintenance free and are light and easy to install. By continuing refinements, abb has learned to master critical operating parameters like vibrations and noise. Aircore reactors acr provide a linear response of impedance versus current which is essential for numerous applications. Since air core reactors do not have a magnetic core to constrain the magnetic field, the magnetic field is broadcast in and around the reactor. Dry type air core reactors are devices which are used at both distribution and. The peec model could also be helpful in design and diagnosis work for aircore reactors. Small nuclear power reactors world nuclear association. This interest in small nuclear power reactors is driven both by a desire to reduce capital. This specification outlines general requirements for design, manufacture, testing, supply and installation of air core reactors, applying to various reactor. In case of a fault in one feeding circuit, the fault current flows only.
The strength of this broadcasted field or more commonly referred to as stray field depends on the power rating of the reactor. Design algorithm of air core multilayer tapped reactor. Wo2016003376a1 multi layered air core reactor design. In general, the higher the kvar rating of the reactor, the higher the strength of the stray field. They are supported by mechanical structures and placed on standoff insulators that define the isolation systems strength against ground potential figure 1.
