INTRODUCTION
|
New developments and applications in electrical and electronic
technology during recent years have resulted in a substantial
increase in the type and number of chokes and reactors being used.
Olsun Electrics Corporation has wide experience in the design
and manufacture of single phase and three phase, air core or iron
core reactors to meet the requirements of specific applications.
Reactors can be designed to meet size and temperature rise limitations
and/or termination requirements.

CHOKE
AND REACTOR DEFINITIONS
|
Current
Limiting Reactors
Intended for series
connection in the supply lines of a system for limiting the current
under system fault conditions. During normal operation of
the system, the nominal line current flows through the reactor.
Line Reactors
Intended for series
connection if the supply lines of variable speed drive systems
to operate as a filter for electrical disturbances, to protect
the system from current surges, and to match the total load impedance
to the variable speed drive.
D.C. Link Reactors
Reactors connected
in the D.C. link between two convertors of differing phase to
limit circulating currents due to instantaneous voltage differences
between the two convertor outputs, and to divide the currents
equally between the two convertors.
D.C. Smoothing Chokes
Intended for series
connection in the D.C. output lines of a rectifier system to attenuate
the ripple in the direct voltage waveform. |
