Home About Us Products Services References Download Contacts Languages Switchers Products More than a disconnector: the switcher The switcher is a device which can open and close a circuit in “on-load” condition. Each COELME-EGIC switcher has been designed to meet specific network-related needs, providing the ideal solution in terms of operation. Among them are, for example (and according to the type of switcher): connection/disconnection of capacitor banks to the network; connection/disconnection of shunt reactors to the network; protection. When provided with an “external” moving arm, switchers can perform the safety functions typical of a disconnector ensuring, in open position, the isolation required and providing, at the same time, “visual evidence” of circuit opening. Switchers differ from each other in their function, type of interrupting chamber (SF6 or vacuum) and in the mechanism driving them (electromagnetic actuator, motor or stored-energy spring mechanism). All COELME-EGIC switchers have been designed to ensure a regular and long service life and to work properly also under the most severe operating conditions (in coastal and/or industrial areas, geothermal areas, in the presence of ice, at extreme temperatures, in seismic areas...). They all share the following features: high versatility easy installation and adjustment low maintenance high reliability high performance Products Capacitor Switcher (CapSwitcher®) The CapSwitcher® has been specifically designed for the connection/disconnection of capacitor banks to the network. ... It is provided with a closing resistor and a “puffer type”, SF6 interrupting chamber, both operated by the same stored-energy spring Reactor Switcher (RLSwitcher®) The RLSwitcher® has been specifically designed for the connection/disconnection of shunt reactors to the network. I ... t is provided with a special, “puffer type”, SF6 interrupting chamber and with a stored-energy spring mechanism. The interrupting chamber, Circuit Switcher (CSH) The circuit switcher was born in the USA to switch and protect transformers and, more generally, loads (reactors, lines, ... cables...), as an alternative to dead tank circuit-breakers which are definitely more expensive. It is provided with a “puffer type”, Line Switcher (LSH) The line switcher has been specifically designed to switch transformers and, more generally, loads like lines and ... cables, in a cheap and reliable manner. It is provided with a “puffer type”, SF6 interrupting chamber and with an operating mechanism Load Switcher (LBS) It is a switch-disconnector combining the features of the SHD vertical-break disconnector with those of its vacuum inter ... rupting chamber. The interrupting chamber is operated by the arm of the disconnector, which prevents the risk of performing erroneous operation Load-break Switcher (VSD) It is a switch-disconnector combining the features of the SLOB vertical-break disconnector with those of its SF6 interru ... pting chamber. Compared to traditional solutions which, for rated voltages above 52 kV, use more than one vacuum chamber connected in series, the Quick Links Download Contact us Products + Disconnectors News 23.12.2014 Season's Greetings 23.12.2014 COELME holidays COELME offices are closed from Wednesday December 24th, 2014 to Tuesday 06th, 2015.
