When the dual power switch device to "Auto (AUTO)" position, the system will be automatically switched state: 1.0 Under normal conditions, (U1 and U2 supply voltages are normal) dual power automatic switch manufacturers, the mother of the circuit breaker Q3 is turned off, the circuit breaker is closed Q1 and Q2; 2.0 when the supply voltage loss U1, U2 supply voltage is normal, and the tie breaker Q3 is off, then disconnect breaker Q1 delayed by t1, the tie breaker Q3 After disconnecting circuit breaker Q1 closed by t2 delay, the two-way power provided by the power supply U2; 3.0 U1 when power returns to normal after the tie breaker Q3 disconnect delay after t3, the circuit breaker Q1 in the master After the tie breaker Q3 is turned off by t4 delay closure; 4.0 U2 when the power loss of pressure, the power supply voltage is normal U1 and the tie breaker Q3 is off, then disconnect breaker Q2 delayed by t1, the tie breaker After Q2 Q3 breaker is closed off by the delay t2 dual power automatic transfer switch, the two-way power provided by the power supply U1; U2 5.0 When the power returns to normal, the tie breaker Q3 disconnect delay after t3 breaker Q2 Q3 after the tie breaker is closed off by the delay t4. 6.0 In shutdown mode, the system does not consider the U1 and U2 supply voltage is normal, the breaker Q1 / Q2 and Q3 will be the tie breaker in the OFF state. t1: from the power U1 (or U2) loss of pressure to the breaker Q1 (or Q2) off delay time t2: disconnected from the circuit-breaker Q1 (or Q2), power supply U2 (or U1) normal to the tie breaker Q3 closed delay time t3: Recovering from power U1 (or U2) normal to the tie breaker Q3 off delay time t4: Disconnect from the tie breaker to breaker Q3 Q1 (or Q2) closed extension When the time delay in the time range, DPT / TE has to return properties. Dual power automatic transfer switch, what does the main application areas, following Xiaobian carefully explain to you: We all know the power of dual-use is very extensive, can be applied to civil construction, financial systems, the military, schools, telecommunications systems, securities systems, medical systems, coal, cement, petroleum, chemical, mining, real estate, heating companies, Heating users, industrial automation systems and other fields. Dual power supply system applications currently houses the power supply system, for emergency load a majority of two-way power with the case of a prepared ATS dual power automatic switch, but there are three of a power supply system with two devices. For this system, you can not rely on a ATSE to complete the conversion. Its solution is: a combination of two ATSE to complete, or three circuit breakers (note whether mechanical linkage) external control and electrical chain to complete. Dual power switch production to perform in accordance with those of national policy standards to national standards GB / T14048.11 just developed for ATSE, production, design, and use of a common standard minimum requirement. The actual design and use will encounter other problems Schneider dual power automatic switch, there ATSE controller and logic problems. I hope the above introduction, allowing readers ATSE technical indicators have a general understanding, combined with their actual engineering situation, more convenient and flexible options and use ATSE equipment, while consistent with the proposed national standard technical specifications.
