 Three-step d.c. switching device (patented SCI principle)  | The modular DEHNguard modular (Y)PV SCI ... (FM) surge arresters were specifically designed for protecting equipment in photovoltaic systems. The innovative patented three-step d.c. switching device (SCI principle) makes these arresters particularly safe so that they fulfil requirements in modern photovoltaic systems. The devices are available as 150 V, 600 V, 1000 V and 1200 V versions for all common voltage levels. The application features of the modular Red/Line family design are similarly unique as the three-step d.c. switching device. The module locking system firmly fixes the protection modules in the base part. Neither shock nor vibration nor the enormous forces of discharge affect the safe connection to the protection module. Nevertheless, the protection modules can be easily replaced without tools by simply pressing the user-friendly module release button of the protection modules. Every protective circuit and every protection module of the DEHNguard modular (Y)PV SCI ... (FM) is mechanically coded to ensure against installing the incorrect module. To fulfil the special requirements in photovoltaic systems, a fault-resistant Y circuit consisting of three varistor protective circuits and a combined disconnection and short-circuiting device are integrated in a single device. This synergy further reduces the probability of an arrester failure in case of operating and fault states which have to be considered in photovoltaic systems. This ensures that the arrester is protected in case of overload without presenting a risk of fire to the system. Even in case of voltages up to 1200 V d.c. a switching arc, which is likely to occur when a conventional disconnector of a surge protective device is triggered, is quenched immediately and above all without risk. Fire protection is the top priority for DEHNguard modular (Y)PV SCI ... (FM). A fuse which was particularly developed for photovoltaic systems was integrated into the short-circuit path. This ensures safe electrical isolation in case of a faulty surge protection module, allowing de-energised replacement of the protection module without arc formation. This unique design combines surge, fire and personal protection. Due to this innovative and unique design, DEHNguard modular (Y)PV SCI ... (FM) can be used in all low, medium and high-performance photovoltaic systems with no need for an additional backup fuse. DG S PV SCI ... (FM) arresters are specifically designed for systems rigidly earthed on the d.c. side; this type of earthing is meanwhile required among others by manufacturers of special thin-film modules or also for legal or normative reasons in some regions. Since either the positive or the negative pole of the PV generator is solidly earthed, the space-saving and thus cost-effective DG S PV SCI ... (FM) arresters (protection module was removed from the Y circuit) may be used if the distance from the earthing point does not exceed 5 m. The green and red indicator flags show the availability of every protective circuit. Apart from this visual indication, DEHNguard modular (Y)PV SCI ... (FM) arresters also feature a three-pole remote signalling terminal. With its floating changeover contact, the remote signal can be used as make or break contact according to the particular circuit concept. As with all surge arresters of the modular DEHNguard modular family, DEHNguard modular (Y)PV SCI ... (FM) arresters incorporate multifunctional terminals on a standardised spacing of 1 module for connecting conductors and busbars, allowing easy wiring with other DIN rail mounted devices. |
