product overview

The KGQ5W series automatic transfer switch is a PC level power automatic transfer device independently developed and researched by our company using patented technology. The product is suitable for power conversion systems in distribution or motor networks with AC frequency of 50Hz-60Hz, rated working voltage of 440V and below, and rated current up to 800A. It is used for isolating circuits and lines that are not frequently connected or disconnected.

The product is widely used in the transmission, distribution, and automation systems of important power supply places such as fire protection, hospitals, banks, and high-rise buildings that do not allow power outages. Update and upgrade products for similar domestic products. The product has a novel design, beautiful appearance, small size, and comprehensive functions, making it the best choice for similar products.

Model and meaning

The product meets the standards

GB/T14048.11-2008 "Low voltage switchgear and control equipment, Part 6: Multifunctional electrical appliances, Part 1: Automatic transfer switchgear"

Normal working conditions of the product

The ambient air temperature does not exceed+40 ℃, and the average temperature value within 24 hours does not exceed+35 ℃; The lower limit of ambient air temperature is -5 ℃;

Structural performance characteristics

◎ The product is novel, beautiful, and practical; Small size, with the same phase spacing as most low-voltage electrical components at home and abroad, easy to install; The execution components adopt independent isolation switches, which are safe and reliable to use; The isolation switch conversion is driven by an AC motor, which is reliable, smooth, noiseless, and has low impact force;

The operator drives the motor to only pass current at the moment of executing the isolation switch conversion, and there is no need to provide working current for steady-state operation, which significantly saves energy. No temperature rise, node welding, or coil burning phenomenon; The isolation switch is equipped with electromechanical interlocking to ensure reliable and non interfering operation of the common and backup power sources;

According to user needs, terminal controllers with voltage loss and phase failure control and basic controllers with voltage loss, phase failure control, undervoltage, and delay control can be provided separately. At the same time, multiple optional functions such as generator control, fire reset, and feedback signals can be added, and the anti-interference ability is strong;

◎ It has a common power supply and a backup power supply; Common power supply and backup power supply combined; There are three stable working states for commonly used power sources and backup power sources;

Easy to install, the control circuit adopts plug-in terminal connection; Manual conversion can be performed using a dedicated handle in manual mode.

Controller function

B basic type: mainly for mains mains mains type, suitable for two mains main and backup systems. When the main power supply circuit loses voltage or experiences under voltage or phase failure, the switch automatically switches into each power supply circuit (with adjustable delay); In the self switching and self restoring working state, when the power supply of the main power supply circuit returns to normal, the switch will automatically switch the load to the main power supply circuit (with adjustable delay). The controller can be set with self switching, non self resetting, and mutual backup functions.
