Automatic Transfer switch
Definition and role: automatic transfer switch is a power circuit for detection, and will be one or more load circuit from one power supply to another power supply automatic transfer of electrical appliances. It is mainly used in emergency power supply system. When the main power supply fails (such as power failure, abnormal voltage, etc.) , it can quickly switch the load to the standby power supply to ensure the continuous and reliable operation of important loads.
Structure and principle: usually by the transfer switch electrical appliances, mechanical interlocking transmission mechanism, intelligent controller, etc. . By detecting the voltage, frequency, phase and other parameters of the main power supply and the standby power supply, the state of the power supply is judged in real time. When the main power supply is abnormal, under the control of the intelligent controller, through the mechanical interlocking transmission mechanism to drive the transfer switch electrical action, power switching is realized.
Performance characteristics: using double row compound contact, transverse connection mechanism, micro-motor pre-storage energy and micro-electronic control technology, basically zero arc; reliable mechanical interlocking and electrical interlocking technology, ensure that two circuit breakers will not close at the same time; using zero-crossing technology, switch conversion is accurate, flexible and reliable; electromechanical design, electromagnetic compatibility, strong anti-interference ability, no interference to the outside world, a high degree of automation.
Application scenarios: widely used in data centers, communication base stations, hospitals, financial institutions, shopping malls, hotels and other places with high requirements for power supply reliability, provide seamless power switching for critical equipment such as servers, medical equipment, fire fighting systems, elevators, etc. to ensure continuous operation of the equipment.
ATS controller
Definition and function: ATS controller is the core control unit of automatic transfer switch. With microprocessor as the core, it can accurately detect the voltage, frequency and other parameters of two power supplies, the abnormal voltage (power loss, over-voltage, under-voltage, over-frequency, under-frequency) is accurately judged, and the ATS switch is controlled after time delay. It also has the function of starting electric generator signal and controlling electric generator stop after abnormal delay of mains power.
Features: wide power supply range, can adapt to different electric generator starting battery voltage environment, mains or generation voltage threshold, various normal delay and abnormal delay parameters can be set; The panel has LED display various operation and alarm status, so that users can intuitively understand the operation of the equipment, switching relays and electric generator relays have large contact capacity, can directly drive the switch to switch on and control the electric generator.
Communication and monitoring functions: some ATS controllers support a variety of communication protocols, such as Modbus, SNMP, etc. , and can be remotely monitored and configured through PCS, intelligent terminals, etc. , it can realize four remote functions such as remote measurement, remote control, remote signal and remote adjustment. Can also send notification alerts through SMS, e-mail and other ways to facilitate the timely handling of abnormal staff.
Working Environment Requirements: usually in a wide temperature range (e. g. -30 °Cー + 70 °C) and humidity range (e. g. 20%ー95%) stable work to adapt to different application scenarios and environmental conditions.
