Intelligent dual power automatic switch range of use and product characteristics: STQ1 series intelligent dual power automatic switch (the ATS) for AC 50HZ, 380V dual power supply system that can be used to complete the power (N) and standby power ( automatic switching R) between, in order to ensure reliability and safety of the power supply. Intelligent dual power automatic transfer switch consists of two molded case circuit breakers and accessories, electrical transmission, mechanical interlocking mechanism, automatic controller and other components, all devices mounted on a metal plate. Intelligent dual power automatic switch controlled by the internal use of intelligent automatic control circuit MOTOROLA microcontroller and advanced, reliable electronic components thereof. Dual power switch works briefly automatic controller is as follows: automatic control of three-phase voltage power supply and standby power used simultaneously detect 120% higher than the rating that ruled over-voltage, lower than the 60-85% ( Specific parameters set by the user) press undervoltage treatment. The internal circuitry of the test results of six voltage amplitude and phase of the judge, and the results after the adoption of the delay WATSGB-32 dual power, driving the corresponding relay instructions issued to electric operation opening and closing instructions. Simultaneously with the detection results of 10 light-emitting diode display on the panel. Through four buttons on the front panel switches, two delay adjustment potentiometer, a voltage adjustment potentiometer can be set to four operating modes ("Auto - Manual", "common power", "standby power", "power failure (re-buckle) ") when the dual power switch device to" Auto (AUTO) "dual power position, the system will automatically switch in the state: 1.0 Under normal conditions WATSGB-400 dual power (mains voltage U1 and U2 are normal ), then disconnect the tie breaker Q3, Q1 and Q2 breaker is closed; 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 in the breaker Q1 Q3 disconnect delay after t2 is closed, 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 breaker Q1 Q3 after the tie breaker disconnect delay after t4 closed; 4.0 U2 when the power loss of pressure WATSGB-200 dual power supply voltage is normal U1 Q3 and the tie breaker in the off state, the circuit breaker Q2 After t1 delay off, the tie breaker in the breaker Q2 Q3 disconnect delay after t2 is closed, the two-way power provided by the power supply U1; U2 5.0 When the power returns to normal, the tie breaker after Q3 t3 delay after disconnecting circuit 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.
