Abstract
A high voltage dry-type reactor is series-connected via a first terminal to an AC supply voltage and via a second terminal to the AC phase terminal of a high voltage converter and includes a cylindrical coil of insulated wire. In order to protect the reactor from a damaging DC field, the reactor further includes a metallic or resistive electrostatic shield which is connected to a same DC potential as the converter.
Claims8
A high voltage dry-type reactor which is series-connected via a first terminal to an AC supply voltage and via a second terminal to an AC phase terminal of a high voltage converter being part of an asymmetric configuration of a high voltage direct current system, the reactor comprising:
- a cylindrical coil of insulated wire, and
- a metallic or resistive electrostatic shield which is connected to the first or second terminal of the reactor.
