SMGQ1-Z dual power automatic transfer switch is our company organized by the scientific and technological elite after two years of painstaking research and development of a new product, launched in late 2014, completely subvert the traditional double power automatic transfer switch shape design style, the design process into the international Industrial design concept, from the product structure, visual appearance, ergonomics, control circuits, etc., to enhance the traditional double-molded plastic automatic dual-switch, so that it has with the international first-class products comparable to the quality and high cost. SMGQ1-Z series dual power automatic transfer switch (referred to as ATS) for rated voltage AC 400V, frequency 50 / 60Hz emergency power supply system. When a power failure occurs, you can automatically switch between the common power supply and standby power, without manual operation to protect the continuity of power supply important equipment. Mainly used for hospitals, shopping malls, banks, chemical industry, metallurgy, high-rise buildings, military facilities and fire power is not allowed to place an important. This product complies with GB / T14048.11 standard, IEC60947-6-1 "automatic transfer switch electrical appliances" standard, "high-rise civil building fire prevention standard", "building design fire prevention standard", "civil building electrical design specification". SMGQ2 series of automatic transfer switch is mainly used for AC 50Hz, rated voltage 400V, rated current 16A to 3200A of the distribution network or a master or standby power switch system and the mains and generator load switching. At the same time can be used for less frequently connected and breaking circuit isolation. Products are widely used in fire, hospitals, banks, high-rise buildings do not allow power to the important places of power transmission, distribution systems and automation systems.

Model and meaning

Main feature

○ Adopting double-column compound contact lateral pull mechanism micro-motor pre-energy storage and micro-electronic control technology, the basic realization of zero arc (no arc hood);

○ The use of reliable mechanical interlock and electrical interlock, the implementation of components using a separate load isolation switch, the use of safe and reliable;

○ Adopting the zero-crossing technology, it can be forced to set zero in case of emergency (cut off two power sources at the same time) to meet the need of fire linkage;

○ Switching load isolation switch using a single motor-driven, reliable and stable switching, no voice, the impact of small;

○ Operators drive the motor only in the implementation of load isolation switch switching instantaneous current, steady-state work without the need to provide operating current, energy-saving significantly;

○ the implementation of load isolation switch with a mechanical interlock device to ensure that commonly used, standby power and reliable non-interference;

○ Has the obvious on-off position instruction, the padlock and so on function, reliably realizes the power source and the load is isolated;

○ safety performance, high degree of automation, high reliability, service life of more than 8000 times;

○ Mechatronic design, the switch conversion accuracy, flexibility, smooth, the use of international advanced logic control technology, anti-interference ability, external interference;

Main power supply, standby power supply; main and standby power are off three kinds of stability (| -o- | |);

○ Easy to install, the control loop using plug-in terminal connection;

 

○ Four operating functions: emergency manual operation, electric remote control operation, automatic control state emergency disconnect operation, automatic control operation.

Working conditions

○ Ambient air temperature: -5 ℃ ~ +40 ℃, and 24h average does not exceed +35 ℃;

○ Atmospheric conditions: the relative humidity of the atmosphere in the surrounding maximum temperature +40 ℃ not more than 50%, at a lower temperature can have a high humidity, in the wettest month on average minimum temperature +25 ℃, the month Of the average maximum relative humidity of 90%, and taking into account the temperature changes due to condensation on the surface.

○ Altitude: The altitude of the installation site should not exceed 2000m.

 

○ Pollution Degree: The environmental pollution level of the installation site is Grade 3.

Basic switching control characteristics

○ Two-way power supply for the main system, since the cast from the complex

○ Can be expanded with external function.

○ Automatic, remote control, manual control function;

○ 0.5s delay detection signal to prevent malfunction;

○ Automatic state with remote control "O" bit;

○ key switch to select the mode of operation;

 

○ Can be equipped with RS-485 communication interface (optional), can be configured according to user needs.
