product overview

KGQ5 Automatic Transfer Switch (ATSE) is an automatic transfer switch that integrates switch and logic control without the need for an external controller, truly realizing mechatronics integration. It is suitable for industrial distribution equipment with rated AC voltage of 50Hz, 440V, and agreed heating current up to 1600A. It has functions such as voltage detection, communication interface, and electrical mechanical interlock, and can realize automatic, electric remote, and forced "0" emergency manual operation. It is widely used for automatic transfer of main power supply and backup or automatic transfer and safety isolation of two load devices in power supply systems. The switch is managed by various logical commands issued by the control circuit board to control the motor. The motor drives the operating mechanism of the switch body to quickly connect and disconnect the circuit or perform circuit conversion, achieving safe isolation through obvious visible states.

Model and meaning

Switch structure description

1. Electrical key lock: controls the power supply of the internal control circuit of the switch. When the electrical lock is turned on, the switch can achieve full movement and strong "0". Operation: When the electrical lock is turned off, the switch can only be manually operated.

2. Operating handle: When manually operating with the operating handle, the electrical lock must be turned off first.

3. Cabinet padlock: maintenance specific, which means first use the operating handle to place the switch in the "0" position, then connect the padlock mechanism and lock it before maintenance can be carried out (connecting the padlock will cut off the internal control power supply of the switch, and the switch cannot be automatic or manually operated).

4. Indicator: Indicate the working status position of the switch (I, 0, II)

Usage

SWITCH

1. Fully automatic function: When the common power supply is cut off, the switch automatically switches to the backup power supply; When the common power supply returns to normal, the switch automatically switches back to the common power supply.

2. Strong "0" function: Activate the strong "0" button, and the switch will cut off the dual power supply.

3. Remote control function: that is, remote control, press the "I" button; The commonly used power supply works; Press the "II" ammonium button to activate the backup power supply; Press the "0" button to cut off the dual power supply.

4. Please select the switch function as needed and wire according to the corresponding function.

5. Please specify the switch model, current specifications, and required functions when placing an order

Performance and characteristics

◎ Adopting double row composite contacts, transverse pull mechanism micro motor pre energy storage and microelectronic control technology, basically achieving zero arcing (without arc extinguishing hood);

◎ Adopting reliable mechanical and electrical interlocks, with independent load isolation switches for executing components, ensuring safe and reliable use;

◎ Adopting zero crossing technology, it can be forcibly zeroed in emergency situations (while cutting off two power sources) to meet the needs of fire linkage;

The load isolation switch switching is driven by a single motor, which is reliable, smooth, noiseless, and has low impact force;

The operator drives the motor to only pass current at the moment of switching the load isolation switch, and no working current is required for steady-state operation, resulting in significant energy savings.

◎ The load isolation switch is equipped with a mechanical interlocking device to ensure the reliable and non interfering operation of the common and backup power sources;

◎ It has obvious on/off position indication, padlock and other functions, reliably achieving isolation between power supply and load;

Good safety performance, high degree of automation, and high reliability;

Integrated electromechanical design, accurate, flexible, and smooth switch conversion, using internationally advanced logic control technology, strong anti-interference ability, and no external interference;

◎ It has a main power supply and a backup power supply; Main power supply split and backup power supply combined; Both the main and backup power sources are disconnected for three stable operations (I-0-II);

Easy to install, the control circuit adopts plug-in terminal connection;

Four operational functions; Emergency manual operation, electric remote control operation, emergency disconnection operation in automatic control state, automatic control operation.

Appearance and installation dimensions

KGQ5-100~1600A Automatic Transfer Switch Control and Operation

◎ The logic control board manages the operation of the motor and gearbox directly installed in the switch through different logic programs to ensure the position of the switch.

The motor is a wet heat type motor insulated with polycarbonate rubber and equipped with a safety device, which trips when the temperature exceeds 110 ℃ and overcurrent occurs. Automatically put into operation after the fault disappears, the reversible reduction gear adopts spur gear.
