switchgear automatic standby input switchboard (ATS)

The ATS is designed to restore power supply to consumers with nominal switching currents up to 630 A by automatic connection of a backup power source in case of disconnection of the main (working) power source resulting in de-energisation of electrical installations of the consumer.
The ATS design includes logical part - makes decisions and switching part - switches inputs. Metrological equipment is located on the latter, which monitors the operating voltage characteristics and allows setting the operating voltage limits.
The first unit includes a logic controller - allows you to set the response time and relay single switch-on. The signalling part or indicators - informs the operator about the status of the sources. Mechanics or switching part is performed on circuit breakers or contactors, which exclude simultaneous connection of the consumer to two outputs due to mechanical and electronic interlocks.
