The RLSwitcher® has been specifically designed for the connection/disconnection of shunt reactors to the network.
It is provided with a special, “puffer type”, SF6 interrupting chamber and with a stored-energy spring mechanism.
The interrupting chamber, in particular, unlike that of traditional circuit-breakers, has been designed to limit the high transient recovery voltage (TRV) values which normally appear when breaking inductive currents.
Thanks to its special chamber, the RLSwitcher® reduces the chances of re-ignition as well as the magnitude of the arc, thus increasing the average service life not only of shunt reactors, but also of the oil-insulated surrounding equipment (power, current or voltage transformers...).
