for UniGear ZS1 switchgear (24 kV)DescriptioniVS1 series medium voltage vacuum circuit-breakers with lateral operating mechanism feature the separate pole construction technique.The operating mechanism is the EL trip-free stored energy type with independent opening and closing regardless of the operator's action. The EL operating mechanism is widely used in all VS1 series circuit-breakers with frontal control.The circuit-breaker can be remote controlled when fitted with dedicated electrical accessories (gearmotor, opening and closing release).The operating mechanism, the three poles and the current sensors (if installed) are assembled on a metal frame without wheels. The construction is extremely compact, strongly built and low in weight. VS1 series circuit-breakers with lateral operating mechanisms are life-long sealed pressure devices (Standards IEC 62271-100 and CEI EN 62271-100). Additionally, VS1 series circuit-breakers have been type tested for low temperature and marine applications (Germanischer Lloyd).VS1 vacuum circuit breakers have been designed for indoor use and air insulated switchboards. AdvantagesVacuum circuit-breakers have particular advantages for use in networks where there is a high switching frequency in the working current range and/ or where a certain number of short- circuit breaking operations are expected. VS1 vacuum circuit- breakers are suitable for auto reclosing and have exceptionally high operating reliability and long life. The circuit- breakers are notable for their compact design, small dimensions together with high capacity. The operating mechanisms have a low maintenance requirement and the interrupters are maintenance- free throughout their service lives. They are well suited to all load breaking operations which occur in practice, and in particular:- Short-circuit currents;
- Overhead lines under load and, no-load conditions;
- Cables under load and no-load conditions;
- Transformers under load and no-load conditions;
- Generators under load and no-load conditions;
- Ripple control system;
- Capacitor banks(also parallel switching) and Motors with starting currents above 600A;
Fields of applicationBelow is the list of SM6 range units used in MV/LV transformer substations and industrial distribution substations:- Cable control and protection
- Overhead control and protection
- Transformers and distribution substations
- Motor and transformer control and protection
- Generator control and protection
- Capacitor bank control and protection
