Description

The switching unit UAZ3037-A (Automatic Transfer Switch) is the new network-group switching device offered by ABB SACE. It is based on microprocessor technology in compliance with the leading electromagnetic compatibility and environmental standards (EN 50178, EN 50081-2, EN 50082-2,IEC 60068-2-1, IEC 60068-2-2, IEC 60068-2-3).

The device is able to manage the entire switching procedure between the normal line and emergency line circuit breakers automatically, allowing great flexibility of settings.
In case of an error in the normal line voltage, in accordance with the delays set, the normal line circuit breaker is opened, the generator started and the emergency line circuit breaker closed. Similarly,when the normal line returns to range, the reverse switching procedure is automatically controlled.
It is especially suited for use in all emergency power supply systems requiring a solution that is ready to install, easy to use and reliable.
Some of the main applications include: power supply for UPS (Uninterrupted Power Supply) units,operating rooms and primary hospital services, emergency power supply for civilian buildings, airports, hotels, data banks and telecommunications systems, power supply of industrial lines for continuous processes.

The switching system consists of the ATS010 unit connected to two motor-driven and mechanically interlocked circuit breakers. SACE Isomax S3, S4, S5, S6 and S7 circuit breakers can be used. The built-in mains sensor of the SACE ATS010 device makes it possible to detect errors in the mains voltage. The three inputs may be directly connected to the three phases of the normal power supply line for networks with rated voltage up to 500V AC. Networks with a higher voltage require the insertion of voltage transformers (TV), setting a rated voltage for the device that matches their secondary voltage (typically 100V).
Two change-over contacts for each circuit breaker connect directly to the motor operator. The circuit breaker connection is completed by wiring the status contacts: Open/Closed, Relay tripped, Rackedin (for draw-out/plug-in circuit-breakers).That is why on every circuit breaker connected to the ATS010 unit, the following are included in addition to the mechanical interlock accessories:
– motor operator from 48 V to 110 V DC or up to 250 V AC
– open/closed contact
– relay tripped contact
– racked-in contact (for draw-out versions)
– signal and mechanical lock for protection relay tripped.
On the motor operator for S6 and S7, the key lock is needed.
The ATS010 device is designed to ensure extremely high reliability for the system it controls. It contains various safety systems intrinsically related to software and hardware operation.
For software safety, a special logic prevents unwarranted operations, while a constantly operative watchdog system points out any microprocessor malfunctions via a LED on the front of the device.Hardware safety allows integration of an electrical interlock via power relay, so that there is no need to use an external electrical interlock system. The manual selector on the front of the device can also control the entire switching procedure, even in the event of a microprocessor fault, by working electromechanically on the control relays.
